As the name suggests, automotive stampings refer to metal stampings composed of automotive parts. In automobile precision metal stamping parts, one part is directly stamped into automobile parts, and the other part needs to be welded, machined or painted to become automobile parts after stamping. There are many kinds of automotive stamping parts, let's discuss them together.

Types of stamping parts

Such as spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, ear, bracket, etc. of automobile shock absorber stamping parts belong to automobiles Stamping. In the selection of materials, first of all, according to the type and use characteristics of automobile stamping, metal materials with different mechanical properties should be selected to achieve the purpose of product quality and material saving.

The selected material should first meet the performance requirements of auto parts; the selected material should have better technical performance; the selected material should have better economy; a large number of cold stamping processes are used in the production of automotive stamping parts, which can meet the automotive stamping parts industry needs a variety of varieties and mass production needs. In medium and heavy vehicles, most of the cover parts such as body panels, the bearings and supports such as frames, and auto parts such as frames are mostly automotive stamping parts. part.

The main steel grades used for cold stamping steel plates and strips account for 72.6% of the total steel consumption of automobiles. Cold stamping materials are closely related to the production of automobile stamping parts. The process design affects the product quality, cost, service life, and production organization, so the reasonable selection of materials is important and complicated work.

The processing materials, equipment, process equipment, and process flow required for the processing of metal stamping parts will be used optimally, in order to ensure that the processing of metal stamping parts can reasonably calculate the product size under normal conditions, and the part size, Accuracy is the best, because customer satisfaction is our recognition.

The selection of stamping parts should meet the following requirements

1. The blanking material should have sufficient plasticity and low hardness to improve the quality and dimensional accuracy of the blanking section. Among them, soft materials (such as brass) have good punching performance, hard materials (such as stainless steel, high carbon steel) have poor punching section quality, and brittle materials are easy to tear during the punching process.

1. The material used for bending should have sufficient plasticity, low yield strength and high elastic modulus. Among them, materials with good plasticity are not easy to crack, and materials with low yield strength and high elastic modulus have small rebounds.

1. The tensile material should have good plasticity, lower yield strength and hardness, and a larger thickness directionality coefficient. Materials with high hardness are not easy to be drawn; materials with a yield strength greater than small plate thickness and directivity coefficient are easy to be drawn.
