Technical field
The present invention relates to a kind of torsion spring processing unit (plant), particularly a kind of spring pin apparatus for bending of deformed spring.
Background technology
Making for special-shaped spring is now Machine automated is not also very universal, and some also need by manual coiling.Process as shown in Figure 3 deformed spring time, need successively through pressing blank, around spring, cut off and the steps such as integer, integer is last one technique of this deformed spring of processing processing, namely be around spring by upper track, the inside symmetrical bending of spring pin of the company's spring after cutting off, the material of torsion spring is light diaphragm flexures steel wire, its hardness is large but elasticity is better, because its hardness is large, intensity is high when bending, present great majority adopt manual coiling to complete, this processing mode is comparatively wasted time and energy, efficiency is also quite low, affect the quality after part final molding, present stage is not also around the specific purpose tool of spring, through extensively retrieval, not yet find ideal technical scheme.
Summary of the invention
The object of the invention is to solve present stage when the spring pin of bending deformed spring, the processing time consuming effort of existence, the shortcomings such as efficiency is low, and the spring pin apparatus for bending of a kind of deformed spring proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of spring pin apparatus for bending of deformed spring, it is characterized in that: comprise fixed head, the sidewall of described fixed head is provided with two mutual corresponding draw-in grooves, fixed head is also provided with a mounting hole, a bending plate is connected by jointed shaft in the side of fixed head, bending plate and described jointed shaft are rotatably assorted, bending plate is fixedly connected with a gear pin, gear pin to be arranged in described mounting hole and to coordinate with its gear, a locating piece is fixedly connected with at the opposite side of fixed head, described locating piece is fixedly connected with an alignment pin, alignment pin and described draw-in groove corresponding matching, bending plate is at least provided with one with the bending groove of described draw-in groove corresponding matching.
On the basis of technique scheme, following further technical scheme can be had:
Described fixed head is also fixedly connected with a support plate.
Described bending plate is fixedly connected with a handle.
Described handle is a platy structure, and the side of handle is socketed on described jointed shaft to be fixed by nut gear, and handle is also connected and fixed by connector and described bending plate.
The preferred screw of described connector, bolt or screw rod.
The side that described bending plate coordinates with described fixed head is provided with an annular boss.
When carrying out the bending of spring pin to spring, the spiral coil of the spring of upper operation coiling is socketed on described alignment pin, herein general by the acute angle of spring down, then the bipod of spring is placed on respectively in two draw-in grooves of fixed head, two pin of spring extend in the bending groove of bending plate always, because fixed head is fixed motionless, during left-right rotation bending plate, the spring pin of spring is under the effect of spring groove and respective card slot, be bent into required angle, then take off spring, then do local shaping with nipper plier.
The invention has the advantages that: this apparatus structure is simple, rotates by fixed head is relative with bending plate, curved for spring go out required shape, its rapid operation, process velocity is fast, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present invention;
Fig. 2 is A-A sectional view of Fig. 1;
The structural representation of Fig. 3 deformed spring.
