Description
Technical field
The present invention relates to rectangular wire spring, especially provides a kind of production work of rectangular wire cluster spring
Skill.
Background technology
Rectangular Section Spring, its making material rectangular cross-section, it has, and installation volume is little, elasticity is good,
Rigidity big (bearing capacity is big), the advantages of precision is high, be highly suitable for that load is high and installing space very
Limited occasion, single-piece Rectangular Spring are currently used primarily in stamping die, die cast metal mould, plastic injection
Plant equipment of mould and precise structure etc..Convex-concave combination Rectangular Spring involved in the present invention, application
In petroleum recovering machinery, external advanced oil production equipment part is still fallen within present.Domestic machinery is to such product
The production and application of product is still in blank, therefore the production technology of the product is necessary to apply for patent of invention.
The content of the invention
It is an object of the invention to provide a kind of rectangular wire cluster spring production technology, concrete technology step
It is rapid as follows：
(1) using mandrel coiling Rectangular Spring (special core shaft structure refers to accompanying drawing 1), it is ensured that rectangle bullet
After spring coiling, steel wire angle of inclination is uniform and be α ± 1 ° (a, steel wire tilt angle alpha value of the present invention
For 14 °, b, spring, can a more than one piece coilings according to mandrel length)；
(2) sizing tempering：280±10℃；
(3) circle, shaping are cut by drawing；
(4) two pieces is carried into same tilt angle and the identical unitary rectangular steel wire bullet of geometric parameter
Spring, convex-concave interlock and spin together, and the termination of two springs is in 180 ° (see accompanying drawing 3) after combining；
(5) it is ground end face, it is ensured that the free height of spring is more than finished product free height 1mm after combination
More than, and ensure the perpendicularity of spring；
(6) swirling flows：Cluster spring punching axle vertical display on forcing press is pressed and processed
(i.e. swirling flows), it is minimum reciprocal 3 times, finally make product reach finished product height, ensureing that spring is vertical
Under conditions of straight degree, it is allowed to which reconditioning end face is to finished product height.
Wherein, using mandrel coiling Rectangular Spring, the mandrel is by around core spindle 2, location-plate for step (1)
3rd, other 4 composition is fixed by location-plate 3 around core spindle 2 (see accompanying drawing 1), and other 4 passes perpendicularly through
Location-plate 3, for fixing Rectangular Spring 1, Rectangular Spring 1 is wrapped on core spindle 2, it is ensured that square
After 1 coiling of shape spring, steel wire angle of inclination is uniform and be certain angle α ± 1 °
Using the rectangular wire cluster spring of technique productions of the present invention, small volume can be met, held
Carry the big technical requirements of power.
Find through test of many times in production：Spring forming angle of inclination directly affects the rigidity of spring,
It is more than 14 ° ± 1 ° when front spring angle of inclination angle is suppressed, and swirling flows rear-inclined angle is changed into
When 13 ° ± 1 °, the physical dimension and mechanical index of spring comply fully with the standard of tolerance model of original product
Enclose, otherwise spring rate can be low, mechanics detection is unqualified.
