Description

Roll shaft type reverse inclined wedge device Technical Field The invention relates to the technical field of stamping die manufacturing, in particular to a roll shaft type reverse inclined wedge device. Background In the field of automobile stamping die manufacturing, upward flanging, upward hole flanging and upward shaping of stamping parts are core processing procedures, accurate shaping is needed to be realized by relying on a special upward-turning wedge mechanism, and as the requirements of the automobile industry on stamping part precision, production efficiency and die service life are continuously improved, the technical evolution trend of low friction, high bearing, long service life and stable shaping of the upward-turning wedge mechanism is increasingly prominent, the performance quality of the upward-turning wedge mechanism directly influences the qualification rate and the production comprehensive cost of stamping products, and becomes a key bottleneck for restricting the high-efficiency application of high-end automobile stamping dies. On one hand, the stamping process is mostly high-frequency and high-load continuous operation, and extremely high requirements are put on the wear resistance and bearing capacity of the wedge mechanism, on the other hand, the tolerance control of modern automobile stamping parts on the forming precision is increasingly strict, and the wedge mechanism is required to maintain stable transmission clearance and action precision in long-term use, so that the problems of incomplete forming, dimensional deviation and the like of the stamping parts caused by the clamping and uneven wear of the mechanism are avoided, and the whole automobile assembly quality is further influenced, and therefore, the development of the upturned wedge mechanism which is adaptive to high-frequency heavy-load working conditions and has the characteristics of accurate transmission and long-term stability is the core requirement in the field of automobile stamping dies. At present, the technical field of the upward turning wedge of the automobile stamping die still has the following defects in the prior art when the upward turning wedge is specifically used, namely the upward turning wedge driven by inclined surface contact friction is driven by inclined surface contact friction, the inclined surface contact friction wedge is driven by sliding friction, the friction force of a contact surface is large, the abrasion resistance is poor, the driving gap is increased after long-term use, the service life of a mechanism is shortened, the blocking failure is easily caused, the production continuity is influenced, frequent shutdown maintenance and adjustment are needed, and the die debugging period and the production interruption time are prolonged.

Therefore, the whole flip structure is short in service life and insufficient in reliability, the problem of fracture repair is required to be processed subsequently, the replacement cost and the labor cost of parts are increased, the production period is prolonged due to shutdown maintenance, the whole production efficiency is affected, and the maintenance cost and the production risk of the die are increased.
