4th step, puts into square rod pickling tube and carries out pickling processes；
5th step, by square rod by drawing the equipment of dialling to carry out cold drawn process；
6th step, repeats the technique of the second to five step at least one times；
7th step, is stretched to the size of drawing requirement by square rod, then carry out just examining, polishing, through after the assay was approved, bag
Dress is transported to subsequent processing or factory carries out part cutting process.
In second step, the temperature of annealing furnace is maintained at 950～1100 DEG C, and temperature retention time is 1～1.5 hour.
In 3rd step, the temperature of solution treatment is maintained at 1000～1150 DEG C, and temperature retention time is 1～1.5 hour；At cooling
During reason, the temperature of coolant is less than 60 DEG C.
In 4th step, before cold drawn process, square rod is carried out drying and processing.
Before at square rod drying, at the surface smear protective layer of square rod.
For the first time after pickling processes, welding welding pull head on pole, after last cold drawn process, on excision square rod
Welding pull head.
After pickling, square rod is carried out reconditioning process by angle grinding machine every time.
In the 6th step, the technique number of times repeating the second to five step is four times.
Beneficial effects of the present invention: after using the technique of the present invention, because in manufacturing process at pickling repeatedly
Reason, the billet surface of pull-out is highly polished；Owing to through annealing repeatedly, solution treatment, the bar of pull-out has the most anti-
Compressive Strength and higher hardness.Therefore, it is good that the mounting bracket using the technique of the present invention to make has outward appearance, and comprcssive strength is with hard
Spend high advantage.
