Small-pore-diameter pipeline cutter capable of achieving automatic feeding

Abstract

The invention relates to the technical field of pipeline cutting equipment, and discloses a small-pore-diameter pipeline cutter capable of achieving automatic feeding. The small-pore-diameter pipelinecutter capable of achieving automatic feeding comprises an outer ratchet wheel mechanism, the interior of the outer ratchet wheel mechanism is in engaged transmission with an inner ratchet wheel transmission block, the interior of the inner ratchet wheel transmission block is movably clamped with a cutting mechanism, and a cutting sample pipe is clamped in the cutting mechanism. According to thesmall-pore-diameter pipeline cutter capable of achieving automatic feeding, due to arranging of an eccentric structure between an inner ratchet wheel transmission block and the cutting mechanism, theinner ratchet wheel transmission block drives the cutting mechanism to rotate and meanwhile exerts inward pressure on the cutting mechanism, through pressure fed back by the cutting sample pipe, the feeding amount of a cutting cutter disc is regulated automatically, the phenomenon that after rotating by a circle, the feeding amount of the cutting cutter disc is manually adjusted each time is avoided, operation is convenient, cutting efficiency is higher, and the phenomenon that during manual adjusting of the feeding amount of the cutting cutter disc, the feeding amount suddenly changes, and the damage to the cutter disc is large can be avoided.

Description

technical field [0001] The invention relates to the technical field of pipe cutting equipment, in particular to an automatic feeding small-diameter pipe cutter. Background technique [0002] The pipe cutter is mainly a portable cutting tool for maintenance, modification and cutting of the installed pipeline. It can flexibly and effectively adjust the cutting diameter according to the diameter of the pipeline within the effective cutting range, and then complete the cutting operation of the pipeline. . [0003] At present, when the existing pipe cutter is working, it can only be driven to perform circular cutting operations. When it needs to adjust the feed rate of the cutter head, it is necessary to artificially force the cutter head to squeeze the pipe inward through external force. Then complete the adjustment and control of the feed rate of the cutter head, the control is more cumbersome, which affects the cutting efficiency of the cutter for the pipe, and when the feed ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a small-diameter pipeline cutter capable of automatic feeding, which can automatically adjust and control the feeding amount of the cutterhead through the feedback pressure of the pipeline, is convenient to control, has high cutting efficiency, and has less damage to the cutterhead. It solves the problem that when the existing pipe cutter needs to adjust the feed rate of the cutter head when it is working, it is necessary to artificially force the cutter head to squeeze the pipe inward through external force, and then complete the adjustment of the feed rate of the cutter head The control and manipulation are cumbersome, which affects the cutting efficiency of the cutter for the pipe, and when the feed rate of the cutter head is adjusted in this way, the feed amount of the cutter head is suddenly changed by external force extrusion, which is very difficult for the cutter head. The damage of the disc is relatively large, which greatly shortens the service life of the cutter disc
