Description
Technical field
The utility model belongs to spring and its molding machine technical field, and in particular to a kind of half drag hook spring forming mould
Tool.
Background technique
Currently, spring using more and more, in order to make spring that there is widely application and better service performance,
The type model of spring is more and more, gradually tends to diversity, and half drag hook spring is in order to meet wanting for installation dimension and performance
It asks, setting drag hook length is less than the half of spring body outer diameter, is designed in this way and increases difficulty of processing, and production efficiency is low, high rejection rate,
Springback capacity is big, and accuracy to size is low.
Summary of the invention
In order to overcome above-mentioned technical problem existing for prior art, the purpose of the utility model is to provide one kind
Half drag hook spring forming mold, shaping efficiency is high, and precision is high.
A kind of half drag hook spring forming mold provided by the utility model, it includes upper trimming die, lower punch, fixed spring mould
Lower punch is arranged in tool, rear fixed spring mold, the fixed spring die nose, and fixed spring mold after the setting of rear end is described
The surface of lower punch is arranged in upper trimming die, and the upper trimming die includes interconnecting piece, fixing seat, pressing part, and the interconnecting piece is equipped with
Screw thread, the fixing seat are cylinder, and the pressing part includes plane side and hemispherical side, the bottom setting of the pressing part
Lug boss.
The prominent bevel angle 12-15 degree of the lug boss, lug boss are designed as the angle R.
The side working face of the lower punch is plane, and upper working face is inclined-plane, and side working face is set with the upper working face place of comparing
There is arc-shaped transitional surface, the side working face and upper working face are equipped with shaping groove, and shaping groove is equipped with forming angle.
Through-hole, the through-hole 0.2-0.4mm big compared with spring outer diameter are equipped in the middle part of fixed spring mold, through-hole wall is provided with U
Shape slot, groove depth are 1 line footpath.
A kind of half drag hook spring, it includes the drag hook of straight tube spring body and straight tube spring body both ends, and the length L of the drag hook is less than
The half of straight tube spring body outer diameter Φ.
A kind of half drag hook spring forming mold provided by the utility model, the beneficial effect is that, structure is simple, user
Just, molding is not easy to spring back, it is ensured that Product Precision and use installation, the prominent bevel angle 12-15 degree of lug boss, in order to open
End circle drag hook position；Lug boss is designed as the angle R, effectively ensures the stabilization and opening size of forming process drag hook size；If
It is 0.2-0.4mm bigger than spring outer diameter to count through-hole diameter, because of change in size at drag hook after molding, opens U-lag, groove depth in middle position
For a line footpath, it is ensured that smoothly take out finished product after molding.
