Description

A kind of scrollwork spring mould
Technical field
The present invention relates to the processing and manufacturing technical field of spring, be specifically related to a kind of scrollwork spring mould.
Background technology
Scroll spring, has another name called clockwork spring, and its one end is fixed and other end effect has moment of torsion, and in the elastic deformation of torsional interaction lower spring material develops curvature, make spring planar produce torsion, the size of its deformation angle is directly proportional to moment of torsion.
Scrollwork spring range of application is comparatively wide, and the knuckle of scrollwork spring effectively can ensure the stability of product, how to control knuckle, ensures the major issue that product quality has become scrollwork spring and produces when therefore producing scrollwork spring.
Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of production efficiency and product with stable quality is high, cost is low scrollwork spring mould.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of scrollwork spring mould, comprise upper die and lower die, patrix described in it comprises curling cover, described upper curling cover end face arranges forming blocks, and described counterdie comprises lower curling cover, and described lower curling cover top arranges lower winding shaft core, cylindrical surface and the axis being parallel of lower winding shaft core arrange groove, groove is while be right-angle side, and another side begins through arc surface and cylindrical tangent rounding off from bottom portion of groove, and the width of groove is the diameter of scrollwork spring silk.
Above-mentioned scrollwork spring mould; counterdie described in it also comprises lower winding shaft core fixed block and last volume axle sleeve top fixed block; lower winding shaft core is placed in lower winding shaft core fixed block, and lower winding shaft core fixed block is placed in the fixed block of last volume axle sleeve top, and last volume axle sleeve top fixed block is placed in lower curling cover top.
Above-mentioned scrollwork spring mould, the lower curling cover described in it is convex shape.
Above-mentioned scrollwork spring mould, the patrix described in it also comprises curling core, and upper curling core is column structure, and an one end face arranges forming blocks, and forming blocks and upper curling core are for removably connecting.
Above-mentioned scrollwork spring mould, the upper curling cover described in it is boss shape, arranges through hole in the middle of it, and described upper curling core inserts in through hole, makes forming blocks higher than upper curling cover, arranges a wire hole with through hole is tangent, and upper curling cover bottom arranges installing hole.
Above-mentioned scrollwork spring mould, the forming blocks described in it comprises two curved surface forming bars, and two curved surface forming bars are insert molded in block, and exceed forming blocks plane, and the gap between two curved surface forming bars is greater than wire diameter.
Beneficial effect:
Can be rotated by the lower winding shaft core in the middle of programme-control after counterdie of the present invention improves on original spool basis, once the knuckle of centre and internal diameter are curled up shaping, internal diameter is little, there is middle angle centre, interference is not had time shaping on axle core, adopt cans can ensure the uniformity of knuckle, be conducive to the stability that rear end external diameter is produced.Its patrix at ± 1 ° by the shaping knuckle angle that can control of forming blocks, is controlled the knuckle of product, effectively can ensure the stability of product by the R angle of forming blocks, ensure to follow the trail of carbon brush stress point consistent with contact surface, reduce the percent defective of product, improve work efficiency, reduce costs.
