Release time:2023-07-17
Precision metal stamping is an important processing method that is widely used in the automotive, electronics, electrical appliances, and communication industries. The main process of precision metal stamping involves rapidly cutting and shaping metal sheets according to the required pattern. Throughout the entire processing process, it offers advantages such as being pollution-free, wear-resistant, burr-free, high precision, and high efficiency. The main process flow of precision metal stamping includes the following stages: cutting stage, stamping stage, bending stage, and surface treatment stage. The editor from a precision metal stamping factory will now provide a detailed introduction, as follows:
1. Cutting stage
Before cutting, it is necessary to sample the sheet material and measure its dimensions, thickness, and mechanical properties. Generally, ordinary sheet materials can be directly processed by punching machines. However, some complex products require multiple stages of processing, such as sheet metal processing. During the cutting process of sheet materials, equipment such as steel shears, hydraulic cutting machines, wire cutting machines, and plasma cutting machines are used.
2. Precision metal stamping stage
The precision metal stamping stage includes processes such as blanking, bending, drawing, and forming. Blanking involves using a press to process the sheet metal into the desired shape; bending involves using a press to bend the blanked sheet metal into the required shape; drawing involves using a press to deep-draw the sheet metal into the desired shape; and forming involves using a press to shape the sheet metal into the required form. The equipment used in the precision metal stamping stage is a press, whose working principle is to utilize the cooperation between the press and the mold to perform precision metal stamping on the sheet metal.
3. Precision metal stamping and bending stage
The bending stage includes processes such as bending, flanging, and leveling. Bending involves using a bending machine to fold the sheet metal into the desired shape; flanging involves using a bending machine to flange the sheet metal into the required shape; leveling involves using a leveling machine to flatten the bent sheet metal. The equipment used in the bending stage is a bending machine and a leveling machine. The working principle of the bending machine is to utilize the cooperation of pressure and molds to perform bending processing on the sheet metal.
4. Surface treatment stage
The surface treatment stage includes processes such as degreasing, derusting, phosphating, and powder coating. Degreasing involves using a degreaser to remove oil and grease from the surface of the sheet metal; derusting involves using a rust remover to remove rust from the surface of the sheet metal; phosphating involves using a phosphating agent to treat the sheet metal with a phosphate coating; and powder coating involves using a powder coating machine to spray and color the sheet metal. The equipment used in the surface treatment stage includes degreasing, derusting, phosphating, and powder coating equipment. The working principle of these devices is to treat the sheet metal through chemical reactions, achieving the desired cleanliness and color on its surface.

The following principles should be adhered to when formulating the sequence for precision metal stamping:
1. Ensure that the mold has sufficient strength and rigidity to prevent deformation or damage during precision metal stamping;
2. Ensure that the workpiece can smoothly enter and be removed from the mold during the precision metal stamping process, while reducing the number of operational steps and operational difficulty;
3. Avoid interference or friction between the workpiece and the mold during precision metal stamping to reduce workpiece damage and mold wear;
4. Ensure convenient positioning and clamping during precision metal stamping to improve processing accuracy and consistency;
5. Consider the safety of operators and avoid interference or friction between their hands or bodies and the workpieces or molds during precision metal stamping processes.
The process flow of precision metal stamping and bending includes the following steps:
1. Cutting: Use a plate shearing machine to cut the plate material to the desired length and width;
2. Bending: Use a bending machine to bend the sheet material into the desired angle and shape;
3. Leveling: Use a leveling machine to level the bent sheet material to ensure flatness and precision;
4. Surface treatment: The plate undergoes processes such as degreasing, rust removal, phosphating, and powder coating to enhance its corrosion resistance and aesthetic appeal.
The equipment used in precision metal stamping and bending processes are bending machines and leveling machines. The working principle of the bending machine is to utilize the cooperation of pressure and molds to perform bending processing on sheet materials. The working principle of the leveling machine is to achieve the required flatness and precision of the sheet materials through the extrusion and bending of rollers.
