Abstract

A kind of screw production technology, it is characterised in that:Include the following steps:(1) it anneals:Wire rod is heated to 900 1000 DEG C, keeps 20 30min, then slowly cool down, to adjust crystalline structure, hardness is reduced, improves wire rod room temperature processability;(2) pickling:The oxidation film of wire surface is removed, and one layer of phosphate film is formed in metal surface, is taken out in line and the process such as cold pier or forming with reducing wire rod, the scratch to tool and mould;(3) line is taken out:Disk member is cold drawn to required line footpath;(4) it is molded:Wire rod is forged through cold, to reach the shape and length (or thickness) of semi-finished product;(5) tooth is rolled over:Molded semi-finished product are rolled over into system or tapping to reach required screw thread;(6) it is heat-treated:High tempering after quenching, 500 650 DEG C of temperature.The invention has the advantages that:Easy to operate, easy high-volume production, screw service life produced by the invention is long.

Description

A kind of screw production technology
Technical field
The present invention relates to Mechanical processing of casting technical fields, and in particular to a kind of screw production technology.
Background technology
Screw is fastened by easy stages using the physics and mathematical principle of the inclined-plane circular rotating and frictional force of object The tool of implements parts.Screw is industrial necessity indispensable in daily life.Screw industrially bears vital task, As long as there is industry on the earth, then the function of screw is forever important.Screw is common in people's production and living over the past thousands of years Invention, from the point of view of application field, it is the first major invention of the mankind.The service life of existing screw is shorter.
Invention content
Technical problem to be solved by the invention is to provide a kind of screw production technologies.
In order to solve the above technical problems, technical solution provided by the invention is:A kind of screw production technology, feature exist In:Include the following steps:
