What is the standard screw manufacturing process?

The screw is the use of the object’s beveled circular rotation and friction of physics and mathematical principles, step by step fastening tools.

Screw is the general term of fasteners, the daily colloquial language.

Screw for the daily life of the indispensable industrial necessities: such as cameras, glasses, clocks, electronics and other use of small screws; TV, electrical products, Musical Instruments, furniture, etc

General screw; As for engineering, construction and bridge, large screws and nuts are used.

Transportation equipment, aircraft, trams, cars and so on for the size of the screw.

Screws have an important role in industry, and as long as there is industry on the earth, the function of screws will always be important.

Screw is a common invention in people’s production and life for thousands of years.

In terms of application field, it is the first great invention of human beings.

The main role of the screw is to connect the two workpiece together, play the role of fastening.

1,The sharp head should be sharp. The screw produced by the screw manufacturer does not make prefabricated holes.

And screws are screwed directly, so the sharp head bears the function of drilling through.

Therefore, according to the national standard, the screw should be inserted into the corresponding machine, or the bad sharp head will lead to drilling.

2, a good screw production process can meet customer requirements and the beauty of the product, so it is necessary to electroplate the screws.

3,In order to heat the screws to the appropriate temperature, it is necessary to keep the time for slowly cooling.

Which is to adjust the crystalline structure, reduce the hardness and improve the normal temperature processing of the wire.

4,The screw manufacturer tells you that the screw can reach the shape and length (or thickness) of the semi-finished product by cold forging (or hot forging).

5,In order to reduce the processing stress caused by cold drawing and ensure the machinability of the screw, the cold drawing of the wire is divided into two stages.

First, the coil is coarsened to a certain wire diameter by using the continuous wire extension machine.

And then annealed to eliminate the processing stress caused by rough drawing.
