A planetary chipless double-knife cutting machine for large-diameter thick-walled PE pipes

Abstract

The invention discloses a planetary chip-less double-blade cutter for large-diameter thick-wall PE pipes. The planetary chip-less double-blade cutter comprises a frame. Power elements, a servo follow-up mechanism, a clamping mechanism and a cutting device are arranged on the frame. The cutting device comprises a mounting board, a power supply device, a turntable coaxial with the mounting board, and a cutting mechanism, and both the mounting board and the turntable are provided with through holes for accommodating pipes. By the planetary chip-less double-blade cutter, the large-diameter and thick-wall PE pipes can be cut effectively, waste of raw materials is reduced, and on the premise of keeping speeds of a cutting trolley and a pipe production line synchronous, pipe quality can be improved while mechanical failure rate is reduced.

Description

technical field [0001] The present invention relates to the relevant technical field of pipe cutting equipment, and more specifically, relates to a planetary chipless double-knife cutting machine for PE pipes with large diameter and thick wall. Background technique [0002] At present, the plastic pipe industry at home and abroad generally uses saw blades to cut large-diameter and thick-walled PE pipes, and it is difficult to realize a chip-free cutting machine. And saw blade cutting will produce the following unsatisfactory state: saw blade cutting is a cutting method for removing materials, so a large amount of sawdust is generated during cutting, and multiple high-power chip suction devices are required for collection and recovery. A large number of production sites and large noises will cause confusion and pollution to the production environment, and it is also not conducive to the health of operators; at the same time, because it is a way to remove materials, it is also...

Problems solved by technology

[0002] At present, the plastic pipe industry at home and abroad generally uses saw blades to cut large-diameter and thick-walled PE pipes, and it is difficult to realize a chip-free cutting machine.

The saw blade cutting will produce the following unsatisfactory state: because the saw blade cutting is a cutting method for removing materials, a large amount of sawdust is generated during cutting, and multiple high-power chip suction devices are required for collection and recycling. A large number of production sites and large noises will cause confusion and pollution to the production environment, and it is also not conducive to the health of operators; at the same time, because it is a way of removing materials, it is also a waste of raw materials, which is accumulated over the years. Neglected Economic Loss

In this cutting method, the incision is not smooth enough, and it needs to be reprocessed when actually laying the pipeline; The method is to clamp the pipe through the clamping device of the trolley, and the trolley is pushed by the pipe to passively synchronize. When producing smaller pipes and thinner pipes, the thrust of the pipe is difficult to overcome the weight of the trolley, which makes the process of passive advancement. The bending of the pipe or the breakage of the cutter affects the product quality and has a high failure rate
