In using, above-mentioned pressure regulation cushion block has following shortcoming:
(1) drawing die is in debug process, often can be because product is wrinkling and the reason such as cracking need to repeatedly be adjusted the charging resistance, and the charging resistance is subject to the tightness between drawbead, pull and stretch groove.If logical adjustment to drawbead, groove is very difficult, the height of normally exchanging the pressure pad piece carries out reconditioning and adjusts, and in the pressure regulation cushion block quantity that a width stretching die uses, often reach tens, charging resistance when the uniformity decision drawbead of its height, the tightness of pull and stretch groove and product draw, so the contour of pressure regulation cushion block is strict, be subjected to the existence of even repeatedly reconditioning mismachining tolerance of secondary, often cause the contour of many equal height cushion blocks to be affected, thereby produce the inconsistent of binder surface distance, the inhomogeneities of pressure-plate-force produces thereupon; (2) for guaranteeing the contour strict conformance of several pressure regulation cushion blocks, exchange reconditioning or the padded necessary cross reference technology that adopts of pressure pad piece, it is very difficult that the secondary maintenance of single pressure regulation cushion block becomes, reconditioning quality or the padded amount of its height must, through adaptive guarantee, not meet the productivity requirement of interchangeability and quick detach, quick change equally; (3) adjustment of reconditioning repeatedly of pressure regulation cushion block, dismantle and assemble also very trouble to it, wastes time and energy, and maintenance cost is high, has had a strong impact on the raising of production efficiency.
The utility model content:
The technical problems to be solved in the utility model is that the cushion block of the pressure regulation in a kind of drawing die is provided.The use of this pressure regulation cushion block, can overcome that above-mentioned prior art exists need to repeatedly adjust the charging resistance time must repeatedly exchange the pressure pad piece and carry out reconditioning, cause repeatedly reconditioning mismachining tolerance and the loaded down with trivial details complexity of reconditioning processing, and dismounting, install, adjust very trouble, waste time and energy, the defect that maintenance cost is high.
Technical solution of the present utility model is:
Pressure regulation cushion block in a kind of drawing die, it is characterized in that, described pressure regulation cushion block is set to raise the pressure pad piece and lowers the pressure pad piece, be provided with multistage descending step on described rise pressure pad piece, be provided with multistage up step on described downward pressure pad piece, the engagement that can mutually be shifted of described descending step and up step.
After adopting above structure, compared with prior art, the utility model is arranged to two of up and down owing to adopting with the pressure regulation cushion block, and at the opposite face of the two pressure regulation cushion blocks in up and down, be provided with multi-stage stairs, the engagement that can mutually be shifted of each step, while adjusting, as long as upper cushion block is moved left and right, the step on upper cushion block will superior displacement or lower displacement be meshed with the corresponding step on lower cushion block.Changing the height of cushion block by the displacement of upper and lower cushion block, is the elasticity of adjusting between drawbead and groove to reach the resistance of adjusting on binder surface.This adjustment structure and adjustment mode, loaded down with trivial details, complicated adjustment structure and the adjustment mode of prior art have been avoided, easy to adjust, quick, the pressure-plate-force good uniformity of transferring, and install, dismantle also very convenient, easy maintenance again, maintenance cost is low, thereby reach, significantly promotes such and draws product mold production and service efficiency.
