Stamping and Automotive

In order to let everyone understand better, first of all, let us briefly understand the process of making four major crafts in a few words. The first step: steel coils and plates are processed into sheet metal parts in the stamping shop and sent to the welding shop. The second step: the welding shop welds each sheet metal piece into a five-door, one-cover, floor, side panel and other assembly parts, and then welds each assembly piece into a body-in-white. The third step: the welded white body is sent to the painting workshop for electrophoresis, spraying and so on. Step 4: Bring the beautiful color of the body to the assembly shop and other parts for the final assembly of the whole vehicle. Below we focus on stamping, from the “stamping” literally can be very simple to understand the use of a press to punch out the product. In fact, the punching is performed by using a press (press) and a mold, and applying an external force by a press, and using the mold to restrict the deformation, the raw materials such as the fresh coil and the rigid sheet are deformed and sheared, thereby becoming The process of designing the shape and size of the product should be designed by the designer. Explain here why, in response to the designer’s request, some other articles on the Internet did not mention the requirements of the designer. I have been working in the manufacturing industry for several years. I deeply feel that the manufacture and processing of products can guarantee the final quality of the products according to the requirements of the designers (personally think that this is the spirit of artisans, I do not know whether the readers agree). Everyone knows that the car is made up of thousands of large and small parts, and the sheet metal parts of the car body are stamped out under the punch of the press shop. Let’s focus on the following. Stamping product flow and stamping process. Stamping product flow chart: Raw materials such as fresh coils and rigid sheets are processed through processes such as cleaning, feeding, processing, and receiving, and the raw materials are processed into products that meet the shape and size of the designer’s design requirements. Stamping product flow, the picture comes from the network. Stamping process: Bending: A method of plastic forming a material such as a rigid web or a rigid sheet which is bent into a certain angle, curvature and shape according to the designer’s requirements. Deep drawing: A stamping processing method in which a raw material such as a coiled material and a rigid sheet is turned into a hollow hollow part by using a mold to form a flat blank obtained by punching. Pull shape: according to the designer’s requirements, the raw materials such as fresh coil and rigid sheet are applied with tensile force to the sheet by the drawing die, so that the sheet material generates uneven tensile stress and tensile strain, and the sheet is then fitted with the pull mold. The surface gradually expands until it is completely conformable to the drawing surface. Spinning: Raw materials such as fresh coils and rigid sheets are used according to the designer’s requirements. The blanks are actively rotated with the spinning mold or the spinning head is wound around the blank and the spinning mold. The spinning head is fed with respect to the core mold and the blank. A method of producing a desired hollow rotor part by continuously deforming the blank. Plastic surgery: The processing method of secondary trimming of the shape of the product by using a plastic mold according to the designer’s requirements. Bulging shape: The raw materials such as fresh coil and rigid sheet are processed according to the designer’s requirements, and the sheet is stretched and thinned to increase the partial surface area to obtain the processing method of the part. Flanging: A plastic processing method in which raw materials such as fresh coils and rigid sheets are bent into vertical sides by bending or straightening the material of the edge of the thin plate blank or the pre-formed narrow edge of the blank according to the designer’s requirements. Shrinking: A method of reducing the diameter of the open end of the flangeless hollow member or the blank of the tube blank, such as the raw material of the coil and the rigid sheet, according to the designer’s requirements. Stamping equipment: The main equipment in the stamping workshop is the punching machine and the mold. Other auxiliary equipments such as: automatic uncoiler, automatic washing machine, automatic feeding machine, etc.
