Petrol Car stamping parts for Geely Car are becoming more and more sophisticated, with more and more varieties, and the market size continues to expand. How to ensure quality has become a key factor for various industries to have increasingly higher quality and precision requirements. There are many reasons for the failure of Petrol Car stamping parts. The selection and operation of Petrol Car stamping parts during the Petrol Car stamping process may also have a negative impact on Geely Car. Stamping parts cause damage, such as clamping, removal and removal of work station equipment, etc. Therefore, details should be fully considered in every aspect of the entire manufacturing process to avoid quality problems as much as possible.
1. Causes
① The quality of purchased steel does not meet national standards, such as unstable materials, out-of-tolerance dimensions, substandard surface accuracy, etc.; iron powder is produced when cutting steel coils; there are burrs on the cross-section after cutting; dirt is attached to the plates when being hosted or transported.
② The Petrol Car stamping die is not installed and used correctly;
③ During the operation of Petrol Car stamping workers, the positioning device for feeding materials was not strictly installed;
④ After long-term use of the mold, due to uneven stress, poor matching of draw beads, or poor control of the press slider, the gap in the mold accessories becomes larger or wears out resulting in scrap;
⑤Loose bolts or other accessories will affect the normal production of the entire mold, because the mold needs to withstand huge impact during the stamping process of Geely Car;
2. Solutions to countermeasures
① When purchasing raw materials, Petrol Car stamping factories must make selections in strict accordance with national standards. When factory conditions permit, steel composition, surface roughness, and dimensional accuracy should be tested. Qualified raw materials are a prerequisite to ensure the quality of Petrol Car stamping parts. When purchasing raw materials, try to choose products from regular steel dealers or large steel factories;
②After the design of the Petrol Car stamping process is completed, the Petrol Car stamping workers must strictly follow the process rules during the operation. Each Petrol Car stamping product has a different Petrol Car stamping process, which requires managers to formulate the process before processing the product. rule;
③ The Petrol Car stamping dies used in the factory must always be in a stable operating state, and periodic maintenance and maintenance of the Petrol Car stamping dies and Petrol Car stamping dies must be carried out; inspection and correction of the drawing molds Periodic inspections and maintenance are required to reduce the occurrence of bumps and maintain a stable condition. The usual approach is to use a sample to check the bonding scratches of the pressure edge ring and the condition of the machined surface (concave mold corner, punch mold).
④ Develop a complete quality inspection company charter. Before formal production, the first batch of products must be fully tested and tested regularly during the production process; problems with the surface of parts in the stamping production of Geely Car are usually uneven problems, mainly due to dust or iron filings adhering to the material or caused by the mold surface. It reduces the surface quality of parts and reduces production performance.
⑤ Appropriate tools must be used for feeding and picking up to avoid scratches on the product;
