Blowing device of multi-station pressure machine

Abstract

The invention relates to the technical field of blowing devices, in particular to a blowing device for a multi-station pressure machine, which comprises a die shank, a cylindrical blowing convex die, two clamping blocks, a material withdrawing core, a cushion block with inner holes and an air supply device used for providing an air source. The lower end of the die shank is fixedly connected with the top of the blowing convex die, an air inlet hole is arranged in the middle of the blowing convex die, a plurality of air outlet holes which are circumferentially uniformly distributed are disposed on the outer wall of the lower portion of the blowing convex die, the air supply device is communicated with the air inlet hole by a pipeline, the two clamping blocks are oppositely disposed on two sides of the bottom end of the blowing convex die, the top of the cushion block contacts with bottom surfaces of the two clamping blocks, and the material withdrawing core is inserted in an inner hole of the cushion block. An airflow method is adopted, the air supply device is used for the blowing device of the multi-station pressure machine, accordingly, strong airflow is conveniently used for blowing impurities away from the surface of a workpiece, simultaneously, the workpiece can be clamped due to the design of the clamping blocks while a correction effect can be realized, and the workpiece can be stably conveyed to a next station.

Description

Technical field [0001] The invention relates to the technical field of blowing devices, in particular to a blowing device for a multi-station press. Background technique [0002] Multi-station press is a fast-developing advanced forging machine. It has the advantages of high automation, high productivity, fewer people, less floor space, safe operation, short production cycle of stamping parts and low overall cost. The transportation and stacking area of ​​semi-finished products are required; the mold is simplified for manufacturing, and has a long service life. The multi-station press is an advanced press equipment, which is an integration of multiple presses, generally composed of a thread head unit, a feeding mechanism, a press and a thread tail part. [0003] When using a multi-station press to process a workpiece, because there are often residues from the previous process on the workpiece, such as small iron filings from the blanking, if these impurities are not removed, they ...
