Zhongshan Precision Sheet Metal Manufacturer: Let's talk about the process flow of sheet metal processing.

　　Zhongshan Precision Sheet Metal Manufacturer: Precision sheet metal processing process flow

　　1. Design and draw the part drawings of the sheet metal parts, also called three views, whose function is to express the structure of the sheet metal parts through drawings.

　　2. Draw the unfolded drawing, which is to unfold a complex part into a plane part.

　　3. There are many ways of blanking.

　　4. Zhongshan Precision Sheet Metal Manufacturer: Flanging and tapping. Flanging, also called drawing, is to draw a slightly larger hole from a smaller bottom hole, and then tap the hole. This can increase its strength and avoid tooth slippage.

　　5. Hole punching processing. Punching processing generally includes punching chamfering, punching blanking, punching convex packaging, punching tearing, and drawing, etc., to achieve the processing purpose.

　　6. Riveting. As far as our factory is concerned, riveting studs, riveting nuts, and riveting screws are frequently used. Their riveting methods are generally completed through a punch press or a hydraulic riveting machine, riveted to sheet metal parts.

　　7. Zhongshan Precision Sheet Metal Manufacturer: Bending. Bending is to fold a 2D flat part into a 3D part. Its processing requires a folding bed and a corresponding bending mold to complete the operation. It also has a certain bending order. The principle is to fold the one that does not interfere with the next knife first, and fold the one that will interfere later.

　　8. Welding. Welding is to weld multiple parts together to achieve the processing purpose or weld single parts at the edges to increase their strength.

　　9. Surface treatment. Surface treatment generally includes phosphating film, electroplating colorful zinc, chromate, baking paint, oxidation, etc.

　　Zhongshan Precision Sheet Metal Manufacturer: How to improve the quality of sheet metal processing?

　　1. Operator factors

　　Controllable measures to prevent defects caused by processes dominated by operators include:

　　(1) Strengthen the quality awareness education of "quality first, customer first", and establish and improve the quality responsibility system.

　　(2) Compile clear and detailed operation procedures, strengthen professional training in procedures, and issue operation certificates.

　　(3) Strengthen the "three inspections", and appropriately increase the inspection frequency (including self-inspection).

　　2. Machine factors

　　The main control measures are:

　　(1) Strengthen the maintenance of equipment, regularly check the key precision and performance items of the equipment, establish a daily inspection system for key parts of the equipment, and control the equipment at the process quality control points.

　　(2) Zhongshan Precision Sheet Metal Manufacturer: First-piece inspection system, verify the adjustment amount of positioning or quantitative devices (such as the one-time positioning accuracy compensation of the rear baffle BG of the bending machine).

　　(3) Use CNC machine tools as much as possible to reduce reliance on the reliability of worker operation.

　　(4) Gradually establish a TPM management system, that is, establish a production and maintenance activity involving all employees of the system, so that the equipment performance can be optimized.

　　 Zhongshan Precision Sheet Metal Manufacturer: I hope the above explanation is helpful to you. Well, I wish you a happy life, and see you next time.
