Abstract
The invention discloses a kind of manufacturing methods of high yield spring, comprising the following steps: Step 1: selection, SWOSL-VHV steel wire；Step 2: roll, by wire rod on coiling machine roll-forming；Step 3: tempering, stress relief annealing, rolled spring are heated to 420 ± 10 in tempering furnaceoC keeps the temperature 1 hour；Step 4: ball blast, is thrown 25 minutes using the shot of 0.8 diameter；Step 5: double tempering, stress relief annealing is heated to 300 ± 10 in tempering furnaceoC keeps the temperature 1 hour；Step 6: hot pressing, at 300 DEG C of pressures simultaneously 5 times.A kind of manufacturing method of high yield spring of the present invention, this method process is simple, and has good high yield performance by the high yield spring that this method obtains.
Description
Technical field
The present invention relates to a kind of manufacturing methods of high yield spring.
Background technique
Existing spring for automobile is higher to the surrender Capability Requirement of spring, and it is difficult that the manufacture of existing high yield spring exists
Degree.
Summary of the invention
The purpose of the present invention is to provide a kind of manufacturing methods of high yield spring, it is intended to be manufactured by this method a kind of high
Surrender spring.
To achieve the goals above, the technical scheme is to design a kind of manufacturing methods of high yield spring, including
Following steps:
Step 1: selection, SWOSL-VHV steel wire；
Step 2: roll, by wire rod on coiling machine roll-forming；
Step 3: tempering, stress relief annealing, rolled spring are heated to 420 ± 10 in tempering furnaceoC keeps the temperature 1 hour；
Step 4: ball blast, is thrown 25 minutes using the shot of 0.8 diameter；
Step 5: double tempering, stress relief annealing is heated to 300 ± 10 in tempering furnaceoC keeps the temperature 1 hour；
Step 6: hot pressing, at 300 DEG C of pressures simultaneously 5 times.
The advantages and beneficial effects of the present invention are: a kind of manufacturing method of high yield spring of the present invention, this method process
Simply, and by the high yield spring that this method obtains there is good high yield performance.
