Winding tube cutting apparatus and method

Abstract

The invention discloses a cutter device of a winding pipe and a cutting method. The cutter device comprises a frame, a support frame of the winding pipe, a cutter device and a moving apparatus; wherein, the frame comprises a fixation frame and a movable frame; the support frame of the winding pipe is connected with the two sides of the movable frame along the direction of the axes of the winding pipe; the cutter device is connected with the movable frame; the moving apparatus is connected with the fixation frame and the movable frame respectively; the moving apparatus drives the moving stand to move in the same speed with the winding pipe; the cutter device comprises a band saw which is transversely arranged under the winding pipe along the direction of the axes of the winding pipe, a lifting guiding element which is vertically connected with the movable frame, a fixation frame of the band saw which is connected with the lifting guiding element in a guiding way and a lifting device which is connected with the fixation frame of the band saw ; the band saw is connected with the fixation frame of the band saw and the terminal surface is arranged in an oblique way. The method comprises the steps of laying out pipes, aligning, starting the moving apparatus, adjusting the cutting side of the band saw, advancing tool step by step to cut until finishing cutting and withdrawing saw, etc. The cutter device of the invention solves the problem about the cutting of the band winding pipes with thick steel bands and satisfies the demand of online pipe cutting.

Description

Technical field [0001] The invention relates to a pipe cutting device, and also to a pipe cutting method, and more specifically, to a winding pipe cutting device and a cutting method. Background technique [0002] The steel-plastic composite winding pipe has been widely used due to its excellent pipe strength, high rigidity and light weight. Due to the complicated structure of the outer wall of the wound tube, it is difficult to realize the horizontal flat cutting. [0003] The existing winding pipe cutting method is to use a circular saw to cut a circle along the helix angle of the pipe during the production process, and then manually cut from the cross section of the strip. This cutting method cannot obtain a flat pipe cutting end surface, the pipe is difficult to use and connect, and the cutting needs to be manually assisted to complete the online automatic pipe cutting. [0004] In order to overcome the shortcomings of the above-mentioned winding pipe cutting method, a circul...
