Description
Technical field
The utility model is related to a kind of automobile dies, and in particular to a kind of material pressing body position limiting structure of mold.
Background technology
It is complex-shaped due to automobile panel, need multistage manufacturing processes to complete, these processes will be pushed down using material pressing body
It is processed again after product.Currently, the working method that the structure of material pressing body is widely used on automobile coverage forming mold is:When
After manufacturing procedure, upper mold is with lathe sliding block uplink, and material pressing body is remained stationary as in the case where being acted on by elastic force, due to spacer pin
It being fixed on upper die holder, with sliding block together uplink, spacer pin can be increasingly closer at a distance from material pressing body for spacer pin and upper die holder,
After lathe sliding block uplink certain distance, spacer pin is contacted with material pressing body, since spacer pin and material pressing body are all made of metal, limit
Position pin is contacted with material pressing body as rigid contact, and when contact generates collision noise, and spacer pin takes up material pressing body after shock, material pressing body
It is detached from molded items.Since each process processing content is different, the size that pressure needed for product is pushed down to material pressing body is also different, pressure
Expect that the reaction force of the bigger release of body pressure is also bigger, for reaction force acts in material pressing body, moment hits the noise generated also just
Bigger, noise is that the most important factor of worker's occupational health is endangered in automobile stamping workshop, if pressing existing punching press condition, especially
It is the continuous application with automatic technology, the rhythm of production of stamping line is getting faster, and the noise of generation is also closer and closer
Collection.Therefore, noise abatement must be carried out from protection employee's hearing and the angle of structure gueen factory, press workshop.Also,
The interaction force that rigid impact generates is bigger, also seriously affects the service life of binder mould.
