Description
Technical field
The invention belongs to automotive parts manufacturing technologies, and in particular to a kind of flat-plate compressed circular arc technique and half versatility
Mould structure and its application method.
Background technique
Clutch is the key component of car transmissions, and diaphragm spring is the key that the member that exerts a force in clutch pack again
The quality requirement of part, the cutting surface that liquidates is very high.The especially punching press section of rivet window, needing to design has destressing circular arc.By
Dynamic model is belonged in general fillet shaping dies, therefore when carrying out the destressing arc machining of diaphragm spring rivet window,
It needs first to carry out clamping to workpiece, the location of workpiece is put and is fixed, and just can be carried out after making Working position face shaping dies
The punch process of fillet;Also need to remove a upper mold when processing the diaphragm spring of different size model numbers, replacement is corresponding new
Mold.However since diaphragm spring rivet number of windows is more, the type of diaphragm spring is also very abundant, industrial to be added using tradition
Construction equipment and method carry out that a large amount of time will be consumed on clamping workpiece and more mold exchange when the processing of high-volume fillet;And often
Scale lamps structure positioning accuracy is difficult to stablize, and if clamping is not in place, then will be greatly reduced yields;While conventional dedicated mold is not
Can a mould it is general, a set of conventional dedicated mould development cost is higher, increases production cost.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to propose a kind of flat-plate compressed circular arc technique and half versatility mould
