A planetary cutting machine for large-diameter pvc pipes

Abstract

The invention discloses a large-caliber PVC pipe planet cutting machine which comprises a rack, a following mechanism, a clamping mechanism, a cutting mechanism, a lifting supporting feeding mechanism, a rotation mechanism and a dust-extraction device, wherein the following mechanism, the clamping mechanism, the cutting mechanism, the lifting supporting feeding mechanism, the rotation mechanism and the dust-extraction device are arranged on the rack. The rotation mechanism comprises a driving gear and a gear rotation disc meshed with the driving gear, and the driving gear is driven by a main driving motor; the cutting mechanism comprises a cutting motor, a cutting swing arm, a cutting shaft and a transmission device, the cutting motor, the cutting swing arm, the cutting shaft and the transmission device are arranged on the gear rotation disc, the cutting motor is arranged on the cutting swing arm, a cutting saw web and a chamfer cutter are arranged on the cutting shaft, the cutting motor drives the cutting shaft through the transmission device to rotate to further enable the cutting saw web and the chamfer cutter to rotate, and an eccentric mechanism for controlling the feeding amount of the chamfer cutter is further arranged on the cutting shaft. The large-caliber PVC pipe planet cutting machine is stable in cutting and attractive, smooth and even in chamfering, and the on-line cutting dust-extraction effect of the cutting machine is good.

Description

technical field [0001] The invention relates to the technical field of cutting machines for PVC pipe production lines, and more specifically, relates to a planetary cutting machine for large-diameter PVC pipes. Background technique [0002] At present, domestic PVC solid-wall large-diameter pipes above Ø630 are rarely produced, and basically produced below Ø630. Since the solid wall pipe needs to be flared at one end and chamfered at one end to facilitate installation and sealing of the pipe, it is necessary to cut the pipe during production and pour out the outer circle of the other end of the cut into a slope of a certain width, and the surface is smooth and even. It is easy to use, install, connect and seal, so the cutting is very strict, not only the cutting speed, but also the cutting accuracy requirements. On the other hand, since the chamfering of PVC pipes requires high-speed cutting and chamfering, saw blade cutting is currently used, but the pipe material is hard ...

AI Technical Summary

Problems solved by technology

On the other hand, since the chamfering of PVC pipes requires high-speed cutting and chamfering, saw blade cutting is currently used, but the pipe material is hard and brittle, and a large amount of dust will be generated during cutting, which cannot be collected well, which is harmful to the environment and the health of the operator; With the improvement of environmental protection awareness, the requirements for dust collection effect are getting higher and higher. Now most of the dust collection device and the cutting machine are separated, and the flexible plastic hose is used for installation and connection. When cutting and vacuuming, the hose starts to pull with the movement of the cutting box. Stretching and being dragged, due to frequent telescopic movements, the plastic tube has poor strength, is easy to be damaged, and leaks air, which makes the vacuum cleaner unusable, and the sealing of the machine is also poor. The chip collection effect is poor during cutting, which is harmful to the operator and the environment.

In addition, the rotary structure of most machine cutting rotary discs uses chain transmission to drive the rotary disc to rotate, and the rotary support of the rotary disc is a small section of arc track composed of bearings, which is difficult to adjust, the rotation is not accurate, and the noise is large; The center cannot be adjusted, once the front and rear clamps are not concentric, it will affect the chamfering quality
