As a stable performance and simple structure of the product, spring is very common in our life.
So spring is how to make?
Torsion spring in the process of production need to meet what are the basic requirements?
the production of
torsion spring are need to pass through the following steps:
(
1)
Ends requirements:
on both ends of the free die forging or upsetting recommended bar top upsetting process, so as to get continuous streams of uniform fibers.
The streamline fiber grain along the torsion bar spring axis direction towards him, and make the shaft to the spline tooth transition metal crystal fiber flow not be disconnected.
（
2)
Surface processing requirements:
the surface of the spring need to have enough machining allowance, guarantee ultimate grinding quantity, also need to ensure the machining accuracy in grinding, grinding is not a mark or marks, etc.
If you don't carry on the processing of torsion bar spring is surface, should put forward table and degree of decarbonization, surface defect and surface size tolerance limit requirements.
（
3)
Spring heat treatment requirements:
heat treatment is the key to improve the strength of spring, the working stress of heat treatment can make spring peak.
（
4)
Surface protection treatment:
to prevent corrosion and mechanical damage on the surface, surface treatment can be used (
Such as phosphating, paint treatment)
And with a rubber belt, nylon fabric, such as epoxy resin paint layer method to protect it.
（
5)
On the material requirements:
raw materials shall comply with the requirements of technical regulations on steel.
Material generally can not have shrinkage cavity, white, hot crack and other defects influence the applicability of the material.
Because the sulfur and phosphorus content of torsion bar spring has great influence on material properties, so their content should be controlled in 0.
Less than 04%, the other is better hardenability.
