Abstract

The invention discloses a stub bar punching device. A rack is provided with an upper die seat and a lower die seat. The bottom face of the upper die seat is provided with multiple punching dies annularly arranged. The top face of the lower die seat is provided with workpiece grooves corresponding to the punching dies. The portion, above the upper die seat, of the rack is provided with a punching air cylinder connected with the upper die seat. The portion, below the lower die seat, of the rack is provided with an ejection air cylinder. The ejection air cylinder is connected with ejector rods arranged in the workpiece grooves. By means of the stub bar punching device, the problems that the manner in which a single workpiece is punched multiple times is adopted and production efficiency is very low in the prior art are solved effectively; and multiple workpieces can be separated through one-time punching, production efficiency is high, the uniformity of products is good, and the stub bar punching device has very high practical value.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a chip punching device capable of cutting multiple plastic or elastic body workpieces at one time. Background technique [0002] In the prior art, a single plastic or elastomer workpiece is cut and separated from the whole mold part, and most of them adopt a single multiple punching processing method, that is, each time the next workpiece is punched from the whole mold part, and the whole mold part is integrally connected. Many workpieces need to go through multiple punching to complete. The production efficiency of this punching method is very low, and the punching surface of each workpiece has certain differences, and the consistency of the workpieces is poor, which affects the quality of the workpieces. The publication date is September 26, 2012, and the patent document with the publication number CN202447479U discloses a cantilever vibrator head cutting device,...
