Cars have been called "the machine that changed the world." Because the automobile industry has strong industrial correlation, it is regarded as an important symbol of a country's economic development level. There are four major automobile processes. The stamping process is the top priority and the first of the four major processes.

1. Stamping concept
Stamping is a forming processing method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stamping parts) of the required shape and size. Stamping and forging both belong to plastic processing (or pressure processing), and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60 to 70% of the world's steel products are plates, most of which are stamped into finished products.
The body, chassis, fuel tank, radiator fins of automobiles, boiler drums, container casings, iron core silicon steel sheets of motors and electrical appliances, etc. are all stamped. There are also a large number of stamped parts in products such as instruments and meters, household appliances, bicycles, office machinery, and living utensils.
2. Stamping process characteristics
A. Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of larger batches of parts and products, facilitates mechanization and automation, and has high production efficiency. At the same time, stamping production can not only strive to achieve less waste and no waste production, but also even if there are edges in some cases The leftover materials can also be fully utilized.
B. The operation process is convenient and does not require the operator to have a high level of skills.
C. Stamped parts generally do not require mechanical processing and have high dimensional accuracy.
D. Stamping parts have good interchangeability. Stamping processing stability is good, the same batch of stamping parts. Can be used interchangeably without affecting assembly and product performance.
E. Since stamping parts are made of sheet metal, their surface quality is good, which provides convenient conditions for subsequent surface treatment processes (such as electroplating and spray painting).
F. Stamping processing can obtain parts with high strength, high rigidity and light weight.
G. The cost of stamping parts produced in batches with molds is low.
H. Stamping can produce parts with complex shapes that are difficult to process with other metal processing methods.
Introduction to stamping process
The mechanical steering system uses the driver's physical strength as the source of steering power, and all mechanical transmission structures are mechanical. The mechanical steering system consists of three major parts: steering control mechanism, steering gear and steering transmission mechanism.
