Automatic slitting equipment for pipes

Abstract

The invention discloses automatic slitting equipment for pipes, and relates to the technical field of pipe processing. The automatic slitting equipment comprises a control system and a rack and further comprises a feeding mechanism, a bearing roller mechanism, a clamping roller mechanism, a conveying mechanism, a cutting mechanism and a discharging mechanism which are arranged on the rack; the bearing roller mechanism is used for bearing and driving pipes to synchronously rotate; the bearing roller mechanism is sequentially provided with a feeding station and a cutting station in the length direction of the bearing roller mechanism; the feeding mechanism is used for conveying the pipes to the feeding station; the conveying mechanism is used for conveying the pipes from the feeding stationto the cutting station; the clamping roller mechanism is used for being matched with the bearing roller mechanism to jointly clamp the pipes; the cutting mechanism is used for cutting off the pipes; the discharging mechanism is used for moving the cut-off pipes out of the cutting station; and a control system is used for controlling operation of all the mechanisms. The pipes are synchronously rotated during tool feeding of a tool, so that the pipes are stressed uniformly, the edge breakage probability is greatly reduced, the rejection rate is decreased, the processing efficiency is improved, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to an automatic cutting device for pipes. Background technique [0002] Pipe slitting is one of the processes of pipe processing. Specifically, the pipe is cut into pipe sections of various lengths according to processing requirements. In the prior art, this process is usually completed with equipment such as a slitting machine. The pipe is fixed on the slitting machine, the knife is approached and cut off the pipe, the knife is retracted after cutting, and the pipe is cut into required lengths of pipe sections repeatedly. [0003] In the prior art, when the slitting machine cuts the pipe, it feeds the knife along the radial direction of the pipe. Since the pipe is in a fixed state, the cutting force exerted by the cutter on the feeding position is relatively large and concentrated in the local area when the pipe is in a fixed state. . Due to the concentration of force, th...

AI Technical Summary

Problems solved by technology

Due to the concentration of force, this cutting method is prone to chipping on the cross section of the pipe. The chipping phenomenon refers to the phenomenon that grooves or notches are formed on the cross section of the pipe due to the concentration of force, resulting in damage to the pipe.

In particular, for some paper tubes with high hardness, their toughness is relatively low. When the above-mentioned slitting machine is used for slitting, edge chipping occurs more frequently, resulting in a higher scrap rate of slitting

On the other hand, the slitting machine in the prior art has simple structure, low degree of automation and processing efficiency
