Pipe pressing cutting device for cutting PVC pipe

Abstract

The invention discloses a pipe pressing cutting device for cutting a PVC pipe. The pipe pressing cutting device comprises a machine frame, wherein a plurality of supporting rollers are arranged inside the machine frame at intervals in a supported mode, all the supporting rollers form a pipe placing plane together, at least two guide sleeves are arranged on a position, between any two adjacent supporting rollers, of the top of the machine frame, a guide column is movably arranged inside each guide sleeve, the upper ends of all the guide columns are fixed with an upper support which is vertically provided with a telescopic air cylinder, and a clamping block is fixed on a piston rod of the telescopic air cylinder. The lower ends of all the guide columns are all fixed with a lower support, a cutting piece is movably arranged inside the lower support in a supported mode, and the cutting piece is driven by a driving mechanism to rotate. When the piston rod of the telescopic air cylinder stretches out, and after the clamping block downward presses the pipe, the surplus route length of the piston rod inside the telescopic air cylinder guarantees that along with continuous stretching-out of the piston rod, the upper support is pushed to move upward, and the cutting piece of the lower support is driven to cut the pipe from bottom to top. The pipe pressing cutting device has the advantages of being capable of improving cutting quality of the pipe.

Description

technical field [0001] The invention relates to a PVC pipe cutting device, in particular to a pipe compression cutting device for cutting PVC pipes with a caliber of 16-32 mm. Background technique [0002] At present, the cutting device used to cut PVC pipes in the market mainly adopts the single motor and pneumatic feed cutting method. The disadvantage of this cutting device is: before cutting the pipe, it must first pass through a pipe clamp that can clamp and fix the pipe. The tightening device fixes the pipe, thereby increasing the production cost of the enterprise, and this cutting device will cause the fracture of the pipe when cutting the pipe with higher calcium content, which affects the cutting quality of the pipe. Contents of the invention [0003] The object of the present invention is to provide a pipe compression cutting device for cutting PVC pipes which can improve the pipe cutting quality. [0004] In order to achieve the above object, the present inventi...
