Scrap-free planetary cutting machine for PE (polyethylene) tubes

Abstract

The invention discloses a scrap-free planetary cutting machine for PE (polyethylene) tubes. The planetary cutting machine comprises a frame. A servo follower and a cutting device are sequentially arranged on the frame. The cutting device comprises a mounting plate, a turnplate, a clamping mechanism, a cutting mechanism and a power source guide device. The turnplate is arranged coaxially with the mounting plate, the clamping mechanism is arranged on the mounting plate, and the cutting mechanism is arranged on the turnplate. The scrap-free planetary cutting machine is reliable in cutting, cuts are free of protruding edges, quality of the tubes can be improved on the premise of speed synchronization of a cutting trolley and a tube production line, and mechanical failure rate is reduced.

Description

technical field [0001] The present invention relates to the related technical field of pipe cutting equipment, and more specifically, relates to a chipless cutting machine for PE pipes. Background technique [0002] At present, there are generally two problems in the cutting of PE pipes in the plastic pipe industry at home and abroad. One is that the cutting method used is unreasonable and the cutting force is uneven, which leads to the incision of the cut pipes. On the one hand, in the pipe production line, it is required that the speed of the cutting trolley and the production line of the pipe must be kept in absolute synchronization during the pipe cutting process. However, the commonly used method in China is to clamp the pipe through the clamping device of the trolley, and the trolley is driven by the pipe to passively synchronize. However, when producing smaller and thinner pipes, the thrust of the pipe is difficult to overcome the weight of the trolley, which causes t...

[0002] At present, there are generally two problems in the cutting of PE pipes in the plastic pipe industry at home and abroad. One is that the cutting method used is unreasonable and the cutting force is uneven, which leads to the incision of the cut pipes. On the one hand, in the pipe production line, it is required to keep absolute synchronization between the speed of the cutting car and the pipe production line during the pipe cutting process. However, the commonly used method in China is to clamp the pipe through the clamping device of the car, and the car is driven by the pipe to passively synchronize. When producing smaller and thinner pipes, the thrust of the pipe is difficult to overcome the weight of the trolley, which causes the pipe to bend or the cutter to break during the passive advancement process, which affects product quality and has a high failure rate
