What are the manufacturing process steps of precision metal stamping parts?

What are the manufacturing process steps of precision metal stamping parts? The precise author will introduce to you from the following aspects. 1. Stamping design (1) The result of stamping design and implementation is a three-dimensional entity with related concepts, such as color, material, hardness, shape, size, location, related parts and manufacturing process. (2) The emergence of computer technology is directly derived from the concept of three-dimensional design, which can more intuitively and accurately express all geometric parameters of the design idea, and can fully discuss the entire design process on the three-dimensional model. (3) Computer technology can help stamping engineers rationalize the design process from a design perspective and gradually create stamping parts from the production of plates and the completion of each process. (4) It can be regarded as the virtual environment of stamping parts. Engineers can design and assemble parts directly on the computer screen. 2. Stamping parts development After the design of stamping parts is completed, it is necessary to convert them into unfolded drawings to determine the size and shape of the required sheet metal. (1) The amount of cad operation is small, and the development process is fully controlled. (2) The computer-aided design is highly efficient and avoids the mistakes that engineers make during the development process. (3) The computer-aided design has high precision, and the extended data is completely calculated by the computer; thereby avoiding a large amount of food cost of materials. 3. Choose stamping oil Stamping oil plays a key role in the stamping process. Good cooling performance and extreme pressure wear resistance are a qualitative leap in the service life of the mold and the improvement of the accuracy of the workpiece. The selection should be made according to the raw materials of the workpiece to match: (1) The choice of carbon steel plate The stamping oil should be determined according to the process and degreasing conditions to determine a better viscosity. (2) Due to the chemical reaction with chlorine additives, when selecting stamping oil for galvanized steel sheets, attention should be paid to the white rust that may be produced by chlorine-based stamping oil, and the use of Edaborun sulfur stamping oil can avoid rust problems, but after stamping It should be degreased as soon as possible. (3) Stainless steel is a material that is easy to harden, and the strength of the oil film needs to be used. 4. Blanking of the blanking board (1) The blanking of the cutting machine is to use scissors to cut the shape of the figure into length and width. If there are punching holes, perform corner cutting, and then rotate the punch and die to perform corner cutting forming. Its advantage is high time efficiency, and it is often used in mass production. (3) First, NC programming and NC punching can be recognized by writing the atlas into the content of the NC machine tool, so that it can mold the shape of the flat part step by step according to the content. (4) Laser cutting is to use laser cutting to cut off the flat structure on the board. 5. The general punching process of machine plate punching includes punching angle cutting, punching blanking, convex bag punching, punching tearing, hole extraction, etc. In order to meet the requirements of each process, a corresponding mold is required. Complete operations, such as punches, tear forming molds. 6. Flat tapping and riveting. Flanging is to draw a slightly larger hole on the smaller bottom hole, and then tap on it. This can increase its strength and avoid slippage. Riveting usually uses riveting bolts, riveting nuts and riveting bolts. The riveting method is usually operated by a punching machine or a hydraulic riveting machine, which can be riveted to the stamped part. 7. Three-dimensional bending of flat plate Bending is to cut flat parts into three-dimensional parts, which requires a folding machine and corresponding bending molds to complete the operation. It also has a certain bending sequence. The principle of lowering the knife will not interfere with the initial bending, and it will produce 8. The surface treatment of the workpiece is generally phosphating treatment, color zinc plating, chromate, paint, oxidation, etc. Phosphating film is generally used for cold-rolled plates and electrolytic plates, and its function is mainly on the material on a protective film on the workbench to prevent oxidation; electroplated multi-color zinc is usually used for surface treatment of cold-rolled plates; chromic acid Salt and oxidation are generally used for surface treatment of aluminum plates and aluminum profiles.
