Do You Know How the Car License Plates Manufactured?

How To Make Car License Plate With Metal Stamping Machines? Because of the developing of the car industry and the growing of the demands for the cars, the car license plates pruduction is rising accordingly. But seldom pepole know how the car license plate manufactured. Now, we would like to show you the process to help you know well. Step 1: We need to decoil the metal material. Then straighten it. In this process, we use the “decoiler straightener 2 in 1” machine from HONGER Machine. Step 2: We will apply a preprinted sheet to the metal sheet. This preprinted sheet has the main color of the plate. It also has reflective material in the coating on the sheet. In this process, we use a “lamination machine”. Step 3: The covered coil sheet is fed into press machine, which is mounted with dies. Then we get a covered metal blank that has the required outline shape. In this process, a feeder, press machine and a pair of dies from HONGER Machine are used. Step 4: We stamp the metal blank to create the raised characters, and the characters are colored with ink. In this process, an engraving machine and a heat pressing machine are used, as well as the heat printing films. After these 4 steps, a car license plate is finished. The reflective sheeting makes license plates easier for law enforcement officials to read by the light of headlights or flashlights, and it is more effective as a safety device on the highway. We HongEr installed many car license plate stamping lines, and the following video showing the machines working in our customer's factory in Sudan.

Overview of TD surface coating treatment technologyTD surface coating treatment technology is short for Thermal Diffusion Coating Process.      Developed in 1972 by the Toyota Central Research Institute of Japan.      In 1973, Japan's TOYOTA and other American auto companies began to apply this technology to automotive molds.      TD surface coating treatment technology is a general term for surface hardening treatment by molten salt immersion plating, electrolysis and powder method (someone in China: molten metal plating). The principle is: The workpiece is placed in a mixture of borax (or other) molten salt, and a layer of metal carbide coating of several micrometers to several tens of micrometers is formed on the surface of the workpiece by high temperature thermal diffusion. At present, the most widely used at home and abroad is vanadium carbide (VC) coating. Due to the high hardness (HV=2800~3200) and tighter structure of these carbides, the performance of TD-treated automotive molds has been greatly improved. Extremely high wear resistance, seizure resistance (strain), corrosion resistance; according to statistics: More than 85% of the molds produced in large quantities in Japan are processed by TD.2. Process flow of TD surface coating treatment technologyAppearance and size inspection (with or without defects in appearance, measuring the size of the insert for easy lifting) → Grinding, polishing (polishing defects, polishing when special) → Degreasing and loading (removing the surface grease of the workpiece, loading the workpiece onto the workpiece holder) →Part preheating (changing the matrix structure and reducing the deformation of the workpiece)→TD coating treatment (treatment temperature 850 °C - 1100 °C, using borax salt bath) → quenching (improving the mechanical properties of the matrix, obtaining the necessary hardness) → back Fire (eliminate the stress of the workpiece) → clean (wash) (remove the borax salt on the surface of the workpiece) → polish (removal of oxides and adherends on the surface of the workpiece) → inspection.3, the advantages of TD processing technology(1) The surface of the automobile mold after TD treatment has high hardness and low friction coefficient;(2) The coating treated by TD is metallurgical bonding and has excellent anti-seizure and anti-strain properties;(3) The life of automobile molds after TD treatment is increased several times, even dozens of times;(4) The corrosion resistance and oxidation resistance of automobile molds after TD treatment are also greatly improved;

What Are The Basics Of Mechanical Press Machine?

What Are The Basics Of Mechanical Press Machine? Mechanical press basicsStamping machine press is the most important and most common in the four major processes of automobile manufacturing.One of the commonly used devices. It mainly relies on the pressing energy of the press to work on the die.The steel plate in the middle is shaped to become the casing of the automobile body.Basic components of the pressThe power energy system includes an electric motor and a flywheel. The electric motor provides a power source and the flywheel acts to store and release energy.The drive train transfers the motion and energy of the motor to the working mechanism. It consists of a belt drive and a gear drive.Working mechanism The working actuator of the press. Generally, it is a crank slider mechanism composed of a crankshaft, a connecting rod, a slider and the like.Support parts such as the body. Connect and secure components to ensure their relative position and motion. The body must withstand all the craftsmanship when working.Operation and control system mainly includes clutches, brakes, electronic and electrical detection and control devices.Auxiliary systems and accessories include pneumatic systems, hydraulics, lubrication systems, air cushions, and quick die changers.Press driveThe main drive system of the press is placed inside the beam:1. The first-class transmission is the “M” type multi-strap belt drive.The main motor transmits energy to the flywheel through multiple zones2. The secondary transmission is a herringbone gear transmissionFlywheel rotation transfers energy to the high speed shaft and then to the herringbone gear3. Three-stage transmission is herringbone or spur gear transmissionThe herringbone gear is transmitted to the straight or herringbone teeth, so that the eccentric wheel is transmitted to the slipper through the connecting rodBlock reciprocatingMain parameters of the pressThe technical parameters of the press reflect the process capability, application range and life of the press.Indicators such as yield are the main basis for the correct selection of presses.  1. Nominal pressure and nominal pressure stroke:    The maximum allowable punching capacity of the press that can be fully absorbed by the structure; that is,The maximum allowable action of the slider when the slider is at a certain distance from the bottom dead centerforce. This specific distance is called the nominal pressure stroke.2, slider stroke      The distance the slider passes from top dead center to bottom dead center. Its size varies with process use and nominal pressure.3, the number of slider strokes     The number of slider strokes means that the slider goes from top dead center to bottom dead point every minute, and then backThe number of times to go to the top dead center. The unit is: spm, the number of strokes per minute.Clutch   The press clutch and brake are used to move or stop the press crank linkage when the motor and the flywheel are continuously rotating. Therefore, the clutches and brakes are transmission components that are indispensable for the normal operation of the press, and the two must work closely and cooperatively.SliderThe mold upper mold is fixed on the slider. During the stamping stroke, the slider moves smoothly up and down.There is an upper air cushion in the slider of some presses.There are also mold clamping devices in the slider of some presses.Some presses also have a quick clamping of the upper die.There is a hydraulic protection device inside the slider. Hydraulic protection is an important protection device for the equipment. The hydraulic protection device consists of a hydraulic pad, a fuel tank, a pipeline, a pressure regulating valve, and a pressure gauge.The guide rail is in contact between the slider and the column, and the contact surface is cooled and lubricated by lubricating oil. There is an oil tank on the column below each rail, and the oil tank is returned to the main tank.There is a balancer between the slider and the beam and the column.It can prevent the slider from falling rapidly due to its own weight when the slider moves downward, causing the gear in the transmission system to be subjected to the force in the reverse direction to cause impact and noise;The gap between the connecting rod and the slider can be eliminated, and the impact and wear of the stressed parts can be reduced;The power consumption of the mold height adjusting mechanism can be reduced;It can prevent accidents caused by the falling of the slider when the brake is broken or the connecting rod is broken.WorkbenchThe lower die of the mold is fixed on the workbench. The press table can be moved for easy and quick mold change.In order to ensure the accuracy of the stamping part, the parallelism of the work surface and the lower plane of the slider is required to be high.The table has a clamping device fixed to the base of the press.electricMost of the electric cabinets of the press are placed on the platform of the electric cabinet. The electrical cabinet is the core part of the press control, and the operator does not allow any components in the power cabinet. But the panel of the electric cabinet must be kept clean.

How To Ensure The Quality Of Cold Punching Production?

How To Ensure The Quality Of Cold Punching Production? Measures to ensure the quality of cold-punching productionIn cold stamping production, there are many factors that cause quality problems, such as failure of stamping equipment or improper maintenance, problems with die installation and adjustment, violation of operating procedures, poor quality of raw materials, and improper process arrangement, which may cause quality problems and even cause waste. In order to prevent the quality of stamping production, the following measures should be taken:1) The raw materials must conform to the technical requirements stipulated by the parts. For parts with relatively high blank size and surface quality, inspection should be carried out. The substitute materials must be approved by the product department or the use department, and must not be claimed.2) All the links specified in the technical regulations must be strictly observed. It is not allowed to arbitrarily change the sequence of operations and omit some auxiliary processes to strictly enforce the process discipline;3) All process equipment should be guaranteed to work in a normal and normal state. In particular, the wear and installation of the die should be observed frequently. A timely repair and maintenance system should be established according to the production batch size and production experience.4) Strict inspection system should be established in production. Generally, there are three aspects: self-inspection, mutual inspection and special inspection.5) Adhere to the implementation of civilized production systems, such as the transfer of workpieces and blanks, should have suitable station equipment to avoid pressing against the surface of the parts, thus ensuring the surface quality of the parts and maintaining the required manufacturing precision. In addition, the interior of the mold should always be kept clean during the stamping process.In short, quality problems often occur in stamping production, and the principle of prevention should be strictly followed. In order to ensure the quality of cold stamping production, it can be summarized as follows: the structure of the workpiece is reasonable, the material properties, size and shape are qualified; the mold design is reasonable; the manufacturing is excellent, the process design is reasonable and the parameters are suitable; the press equipment is intact and the operation is reasonable.

What Is Stamping Process?

What Is Stamping Process? Stamping process introduction1. Cold stamping: refers to a pressure processing method that obtains the required parts by applying pressure to the material at a normal temperature by using a die mounted on the press to cause separation or plastic deformation.2. Features of cold stamping:        Stable product size, high precision, light weight, good rigidity, good interchangeability, high efficiency, low consumption, easy operation, easy automationCold stamping is generally divided into two categories: separation process and forming process1. The separation process is to form a stamping of a certain shape, size and cut surface quality by separating the sheets according to a certain contour line.2. The forming process is a stamping in which the blank is plastically deformed without breaking, thereby obtaining a certain shape and size.Process supplementThe process supplement section should consider the following three requirements:1. Delayed feed conditions2. The shape and position of the binder surface.3. The position of the trimming line and the way of trimming.There are two types of binder surfaces:1. It consists of the flange surface of the workpiece itself;2. It consists of a supplement to the process;Formulate the basic principles of the binder surface:1. In order to reduce the depth of drawing, the pressing surface can be designed into a certain curved shape to bend the blank into a certain shape before drawing. However, the shape of the pressing surface should be as simple and smooth as possible to prevent the blank from wrinkling during the pressing process, and to facilitate the flow of the material into the concave mold during the drawing.2. Between the shape of the pressing surface and the shape of the punch, a certain geometric relationship should be maintained - to ensure that the blank is in tension during the drawing process, and can smoothly and gradually adhere to the punch to prevent wrinkles. To this end, the following relationship must be satisfied: the length of the binder surface The difference between drawing and forming1. When the forming depth of the part is greater than 10MM, it is better to use the drawing method to avoid the phenomenon of extrusion.For less than 10, it can be considered to be used for molding. At the same time, in order to avoid stacking, the process gap is usually added.2. Drawing generally requires a complete process replenishment surface and a binder surface, and is a closed geometry.But molding can only be made locally, not all closed3. The same material grade of the same part, the product obtained by drawing or forming process, the former in terms of rigidityStronger than the latter.4. Parts are close to closed parts, preferably drawn, and open can be molded.Reasons for adding blanking processA. When the difference between the widths of different parts of the same part is more than 30%, consider adding the blanking die, otherwise it will be difficult to form.B, improve material utilizationC. The sheet before molding has a large area without forming part of the formed part.The difference between unwinding and blankingA. The parts of the product are large, and the manual operation of the parts with high labor intensity is as close as possible.material.B. Compared with the ordinary blanking die, the parts that can improve the material utilization rate are unrolled.Blanking.C. The width of the coil required for the blank is too small or too wide to be used for unwinding and blanking.A common blanking mode is required.D, parts routing planning parts produced on the automation line, the best blanking dieUse unwinding and blanking.

What Are Basic Process And Arrangement Of Stamping Process For Automotive Cover Parts?

What Are Basic Process And Arrangement Of Stamping Process For Automotive Cover Parts? Basic process and arrangement of stamping process for cover parts     The basic processes of the stamping process of the cover are: blanking, drawing, shaping, trimming, flanging and punching.     In actual production, some processes can be combined: blanking, trimming, trimming, trimming, and punching.     The shape of the cover is mostly formed mainly in the drawing process.The blanking process is mainly to obtain the shape and size of the blank required for the drawing process.     The main content of the shaping process is the shape of the cover that has not been formed in the drawing process.     The main content of the trimming process is to cut off the process replenishment on the deep drawing. These process supplements are only required for the drawing process and are cut off after the drawing is completed.     The flanging process is located after the trimming process, and the main task is to form the edge of the cover.     The punching process is used to machine various holes in the cover. It is usually carried out after the drawing or flanging process.

What are characteristics of automobile body panel stamping forming?

What are characteristics of automobile body panel stamping forming? Body panel stamping forming characteristics1. One-time deep drawing    The current theoretical analysis and technical level are not as analytical and computational as the cylindrical axisymmetric parts. Therefore, the design of the cover product is required to be combined with the stamping process to ensure a one-time deep drawing on the basis of small deformation and shallow drawing.    Therefore, it is required to realize stamping of the cover with a minimum depth of drawing, a minimum of stamping steps, and a mold structure as simple as possible.2. Incremental composite molding    The shape of the cover is complicated, and the deformation of the blank is generally not a simple deep drawing deformation, but a composite molding in which both drawing and bulging are present.3. Partial molding    When a part having a partial shape (protrusion or recessed) inside the contour is press-formed, the partial forming starts to be formed when the punch is lowered to a certain depth due to the function of the blanking force, and is completely pasted at the end of the molding.4. Deformation path change5. Deformation trend control    The main measures to control the deformation tendency of the stamping forming of the cover are to determine the reasonable punching direction, determine the pressing surface, and rationally design and set the drawing rib.    The drawing direction, the process replenishment and the shape of the pressing surface are prerequisites for determining whether or not to deepen the covering member, and the rational laying of the drawing ribs for controlling the entire drawing blank is a necessary condition for ensuring the drawing of the qualified covering member.
