A rotary punching device for automobile seals

Abstract

The invention relates to a rotary punching device for automobile seals, which comprises a fixed bottom plate, a rotating fixed block is installed at both ends of the upper surface of the fixed bottom plate, a rotating arm is installed on the top of the fixed bottom plate through a rotating shaft, and a power mechanism is arranged above the fixed bottom plate. The power mechanism is connected with a Y-shaped double-knuckle joint and a connecting arm. The Y-shaped double-knuckle joint is hinged to one of the rotating arms, and the connecting arm is hinged to the other rotating arm. A cutter is installed at the bottom of the inner surface of the rotating arm. A die is detachably installed on the side under the cutter. The present invention is driven by a single power mechanism, and uses a plurality of rotating arm structures to convert the horizontal telescopic movement of the power mechanism into the rotating motion of the left and right rotating arms, respectively driving the respective cutting knives to rotate in the direction of the die, so as to achieve relatively accurate positioning. The punching of deep glass edge lip notch has compact structure and good power balance, which increases the selection range of power mechanism stroke, reduces the time of assembly and debugging, and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile seal processing, in particular to a rotary punching device for automobile seals. Background technique [0002] For the incision processing of the automotive roof strip seal with complex glass edge lip shape and deep incision position, the existing structure needs to use two power units to drive, each power unit mechanism is equipped with corresponding parts such as cutter and die, and The various electrical components matched with it are punched on the left and right sides of the edge glass lip of the top strip respectively. The structure is not compact, it is inconvenient to arrange the cutter die, and the punching at the specified incision position cannot be realized. Scrap is hard to drop. SUMMARY OF THE INVENTION [0003] The invention aims to solve the deficiencies of the prior art, and provides a rotary punching device for automobile seals. [0004] The present invention adopts the fo...
