Description

Automobile hardware processing method
Technical Field
The invention relates to the field of automobile hardware, in particular to a method for machining automobile hardware.
Background
With the development of scientific technology, the living standard of people is higher and higher, and the requirements on products are higher and higher. In the field of automobiles, the types of automobiles are various, various technologies are more and more mature in application, and related hardware is more and more endless. Automobiles are used as vehicles, and the related hardware is required to have high performance and high safety. At present, the steps for preparing automobile hardware in the market are still required to be further improved so as to meet the increasingly developed automobile technology. Therefore, a hardware processing method needs to be designed to ensure the quality and safety of the hardware and meet the requirements of modern automobile development.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the automobile hardware processing method which is simple in process, ensures the quality and can meet the requirements of modern automobiles.
The technical scheme adopted by the invention is as follows: the method is characterized by comprising the following steps of:
(1) installing the first main die, the second main die and the third main die on a cold forging machine, and adjusting the highest point of the wire rod to pass through;
(2) adjusting the verticality between the scissors and the center line of the hardware wire rod to ensure that the end surface of the hardware wire rod cut by the scissors is as flat as possible;
(3) adjusting the wire pressing wheel and the wire feeding wheel to smoothly feed the hardware wire into the cold forging machine;
(4) installing the first stamping die, adjusting the contact ratio of the first stamping die and the central hole of the first main die, and performing primary cold forging;
(5) adjusting the contact ratio of the wire clamping jaw and the center line of the die to enable the machining size to be within the required tolerance range, installing the second stamping die, adjusting the contact ratio of the second stamping die and the center hole of the second main die, and performing secondary cold forging;
(6) and adjusting the contact ratio of the wire clamping jaw and the center line of the die to enable the machining size to be within the required tolerance range, installing the third punching die, adjusting the contact ratio of the third punching die and the center hole of the third main die, performing cold forging for the third time, and finally obtaining a finished product.
Further, after the step (3), the method further comprises the following steps: adjusting the feeding length of the wire feeding wheel to enable the feeding length to be 1-2 m longer than the actually required length, and adjusting the size of the required wire by using the material ejecting rod. Therefore, the allowance of the supplied materials is reserved in the machining process, the quality is guaranteed, and the phenomenon that the machine is suddenly stopped due to the lack of the supplied materials, so that the cold forging quality is influenced is avoided.
And (3) in the step (2), adjusting the verticality between the scissors and the central line of the hardware wire by using a test needle with the aperture smaller than that of the die by 0.02 mm. Thereby ensuring the processing accuracy of the subsequent cold forging process.
The invention has the beneficial effects that: according to the invention, the wire is subjected to three times of cold forging through the matching of the first main die and the first stamping die, the second main die and the second stamping die, and the third main die and the third stamping die, and after each time of cold forging, the precision of product processing is ensured by adjusting the contact ratio of the wire clamping jaw and the center line of the die, so that quality assurance is provided for the final hardware product.
