Description

Cold heading blank of automobile seat part

Technical Field

The utility model relates to the technical field of automobile part production, in particular to a cold heading blank of automobile seat parts, which is used for conveniently and rapidly producing the automobile parts in a large scale.

Background

The parts related in the project are important parts in the automobile seat and are used for various automobile types under the flag of a certain international well-known automobile company, and the parts are made of low-carbon steel and have relatively complex tooth shapes and meshed with other parts. The function of the device is to adjust and maintain the height, angle, front and back positions and other postures of the automobile seat. The design life of the piece is equal to the life of the whole automobile, and the piece is not replaced in the service cycle of the automobile. Moreover, the part has high use frequency due to frequent adjustment. Therefore, the requirements on the external dimension of the product and the mechanical strength of the whole part are high in the technical aspect. The defects such as cracks, internal looseness, air holes and the like are not allowed to exist, and the wear resistance and corrosion resistance are required to be higher, so that the long-time practical use is met.

In the use process of the part, once the part fails and breaks, the seat part can be separated, the state of the whole seat can be out of control, and if the part runs at a high speed, serious consequences can be caused, so that the quality of the product is very important, and the personal safety of a person is concerned.

The manufacturing process adopted before the part is to use a solid round steel bar as a raw material, adopt machining equipment and processes such as drilling, turning, gear milling, gear grinding and the like to produce, the machining amount in the part production process is quite large, the production flow is complex, the material waste is serious, the machining efficiency is quite low, and the part can meet the production requirement of small batches. For the production of tens of thousands of products, the operator repeatedly performs mechanical labor for a long time, and the parts such as eyes, hands, shoulders and the like are extremely tired; and the production efficiency is low, and each person can finish the production of less than 100 products every day. For tens of thousands of automobile brands in a month, the product needs to be supplied with more than 5 tens of thousands of goods per month, and the conventional machining method needs a large number of lathes in a large scale to meet the production quantity, so that the production investment is huge.

And the utilization rate of the metal raw materials is only about 30% by adopting the mode of the method, a large amount of precious raw materials are changed into scrap waste residues, the production cost is increased, the environment is polluted, and the method does not accord with the energy-saving and low-carbon manufacturing concept proposed by the current country.

In view of this situation, there is an urgent need for a production method that can be efficiently and quickly performed on the production site.
