Abstract
Disclosed is a method for producing high intensity nuts. The producing method comprises steps as follows: (1) blanking and preprocessing; (2) cold heading and piercing; (3) quenching; (4) galvanizing; (5) tapping and obtaining the high intensity nuts. The invention provides a method that can enhance the intensity and quality of nuts for producing high intensity nuts.
Description
Technical field
The present invention relates to a kind of production method of the high strength nut of making by carbon steel.
Background technique
In high strength carbon steel nut production process, the Chang Yinwei technological problems causes the nut Material Strength to reduce, and sliding tooth takes place nut in use destroys.
Summary of the invention
For the deficiency that nut strength is lower, nut is second-rate of the production method that overcomes existing high strength nut, the invention provides a kind of production method that can strengthen nut strength, improve the high strength nut of nut quality.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of production method of high strength nut, described production method may further comprise the steps: (1), blanking and pretreatment; (2), cold-heading, punching; (3), quench; (4), galvanizing by dipping; (5), tapping, make high strength nut.
As preferred a kind of scheme: in described step (3), described heat treatment is 860～870 ℃ of quenchings, cools off in the CL-1 quenching medium.
As preferred another scheme: in described step (4), described galvanizing by dipping is the low temperature galvanizing by dipping, and its temperature range is 455～480 ℃.
Beneficial effect of the present invention mainly shows: compare with existing plain nut production technology, have the cost increase less, characteristics that nut strength is high.
Description of drawings
Fig. 1 is the flow chart of the production method of high strength nut.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1, a kind of production method of high strength nut, described production method may further comprise the steps: (1), blanking and pretreatment; (2), cold-heading, punching; (3), quench; (4), galvanizing by dipping; (5), tapping, make high strength nut.
In described step (3), described heat treatment is 860～870 ℃ of quenchings, cools off in the CL-1 quenching medium.
In described step (4), described galvanizing by dipping is the low temperature galvanizing by dipping, and its temperature range is 455～480 ℃.
Compare with existing plain nut production technology, have the cost increase less, the nut strength height Advantage.
Claims (3)
1, a kind of production method of high strength nut is characterized in that: described production method may further comprise the steps: (1), blanking and pretreatment; (2), cold-heading, punching; (3), quench; (4), galvanizing by dipping; (5), tapping, make high strength nut.
