What are the manufacturing process steps for precision Metal Stamping parts? Yiwei Precision Editor will introduce you from the following aspects.

1. Stamping part design

(1) The result of stamping part design and implementation is a three-dimensional entity with relevant concepts, such as color, material, hardness, shape, size, position, related parts, and manufacturing process. (2) The emergence of computer technology directly stems from the concept of three-dimensional design, which can more intuitively and accurately express all geometric parameters of design ideas, and can fully discuss the entire design process on a three-dimensional model. (3) Computer technology can help stamping engineers rationalize the design process from a design perspective and gradually create stamped parts from the production of sheet metal and the completion of each process. (4) It can be regarded as a virtual environment for stamping parts. Engineers can design and assemble parts directly on computer screens.

2. Stamping component development

After the design of stamped 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 operation volume of CAD is small, and the development process is fully controlled. (2) Computer aided design has high efficiency, avoiding errors that engineers are prone to make during the development process. (3) Computer aided design has high accuracy, and the extended data is completely calculated by the computer; This avoids the significant food cost of materials.

3. Choose stamping oil

Stamping oil plays a crucial role in the stamping process. Good cooling performance and extreme pressure wear resistance have made a qualitative leap in the service life of molds and improving workpiece accuracy. The selection should be based on the raw materials of the workpiece to match: (1) The selection of carbon steel plate stamping oil should determine a better viscosity based on the process and degreasing conditions. (2) Due to the chemical reaction with chlorine additives, when selecting stamping oil for galvanized steel plates, attention should be paid to the possible white rust caused by chlorine type stamping oil, and the use of Yida Borun sulfur stamping oil can avoid the problem of rust, but degreasing should be done as soon as possible after stamping. (3) Stainless steel is a material that is prone to hardening and requires the use of oil film strength,

4. Blanking board cutting (1) The cutting machine uses scissors to cut the shape of the shape into length and width. If there is punching, corner cutting is performed, and then the punching machine is combined with the punching die to form the corner cutting. Its advantage is high time efficiency and it is often used for mass production. (3) Firstly, CNC programming is used for CNC punching, and the pattern is written into the content of the CNC machine tool to identify it. Based on the content, the shape of the flat part is sequentially molded. (4) Laser cutting is a method of cutting flat structures off a board using laser cutting.

5. The general punching processes for machine tool boards include angle cutting, punching and material dropping, convex bag punching, punching and tearing, hole extraction, etc. In order to meet the requirements of each process, corresponding molds are required to complete the operation, such as convex molds and tearing forming molds.

6. Flat tapping and riveting

Flipping is drawing a slightly larger hole on the smaller bottom hole and then tapping it to increase its strength and avoid slipping teeth. Riveting usually uses riveting bolts, riveting nuts, and riveting bolts. The riveting method is usually operated by a stamping machine or hydraulic riveting machine, which can be riveted to the stamped parts.

7. Three dimensional bending of flat plates

Bending is the process of cutting flat parts into three-dimensional parts, which requires a bending machine and corresponding bending molds to complete the operation. It also has a certain bending sequence, and the principle of cutting will not interfere with the initial bending, which will produce eight. The surface treatment of the workpiece generally involves phosphating, zinc plating, chromate plating, paint, oxidation, etc. Phosphating film is generally used for cold-rolled and electrolytic plates, and its main function is to prevent oxidation on a protective film on the worktable; Electroplating multi-color zinc is commonly used for surface treatment of cold-rolled sheets; Chromate and oxidation are generally used for surface treatment of aluminum plates and profiles.
