Abstract

The invention discloses a plastic pipe broaching device. The plastic pipe broaching device comprises a machine frame, a front sleeve, a rear sleeve, a fixing barrel, a connecting disk, a connecting frame, first broaching petal bodies and second broaching petal bodies. The front sleeve and the rear sleeve are connected through the fixing barrel. The rear sleeve is fixed to the machine frame. The two side faces of the connecting disk are connected with first racks and four first sliding bars separately. The two sides of the connecting frame are connected with a guide pillar and four second sliding bars correspondingly. The four first sliding bars and the four second sliding bars are alternately arranged at intervals and are further evenly distributed in the circumferential direction. The first sliding bars and the second sliding bars are arranged in all sliding chutes of the outer circumferential face of the fixing barrel in a sliding mode. According to the plastic pipe broaching device,a driving shaft is used for driving the first racks and a second rack to move step by step, and the first broaching petal bodies and the second broaching petal bodies can form a whole broaching bodyafter being unfolded completely. The structural design is novel, working efficiency is high and practicability can be achieved.
