Corrugation pipe cutting machine

Abstract

The invention discloses a corrugation pipe cutting machine, which comprises a frame which is provided with a cutting mechanism, a feed mechanism, a feed wheel gap adjusting mechanism and a control mechanism. The feed mechanism comprises an upper belt wheel group, a lower belt wheel group, a first driving mechanism and a first transmission mechanism connected with the power output end of the first driving mechanism. The upper belt wheel group and the lower belt wheel group are connected with the first transmission mechanism, a gap between the upper belt wheel group and the lower belt wheel group can be adjusted through the feed wheel gap adjusting mechanism, and the control mechanism is electrically connected with the feed mechanism, the cutting mechanism and the feed wheel gap adjusting mechanism. The cutting mechanism comprises a lower cutter arranged on the frame and a second driving mechanism, the power output end of the second driving mechanism is connected with a connecting rod mechanism, an upper cutter seat is connected onto the connecting rod mechanism, the upper cutter seat is arranged on the frame through a guiding mechanism, and an upper cutter is arranged on the upper cutter seat which can drive the upper cutter and the lower cutter to cut through guide of the guiding mechanism.

Description

technical field [0001] The invention relates to a pipe cutting machine, in particular to a corrugated pipe cutting machine. Background technique [0002] Corrugated pipes are widely used in industry today, and can be used in drainage and ventilation pipes of mines and buildings; chemical ventilation pipes and chemical and mine fluid delivery pipes; high-voltage cables, post and telecommunications cable protection casings, etc. A special machine (corrugated pipe cutting machine) cuts it into a certain length. The feeding mechanism of the traditional corrugated pipe cutting machine mainly adopts the structure of several feeding wheels that are in rolling friction contact with the pipe fittings. The friction generated by the pipe makes the pipe move forward to complete the feeding process. During the above feeding process, the feeding wheel and the pipe are in tangential contact, which leads to large errors in feeding length, inaccurate feeding, and instability. [0003] The c...

[0002] Corrugated pipes are widely used in industry today, and can be used in drainage and ventilation pipes of mines and buildings; chemical ventilation pipes and chemical and mine fluid delivery pipes; high-voltage cables, post and telecommunications cable protection casings, etc. A special machine (corrugated pipe cutting machine) cuts it into a certain length. The feeding mechanism of the traditional corrugated pipe cutting machine mainly adopts the structure of several feeding wheels that are in rolling friction contact with the pipe fittings. The friction generated by the pipe makes the pipe move forward to complete the feeding process. During the above feeding process, the feeding wheel is in contact with the pipe at a tangential point, which leads to problems such as large feeding length error, inaccurate feeding, and instability.

[0003] The cutter mechanism of the traditional corrugated pipe cutting machine adopts a cylinder structure, which needs to be distributed with compressed air source, so the cost is high; and its cutting force is small, the action is slow, so the efficiency is low; the knife of the cutter mechanism of the traditional corrugated pipe cutting machine Rack guidance, inaccurate positioning and other issues
