PVC (polyvinyl chloride) pipeline cut-off equipment

Abstract

The invention belongs to the technical field of cut-off equipment, and particularly relates to PVC pipeline cut-off equipment which comprises a machine body. A supporting opening is formed in one side of the machine body, a cutting knife is connected to the top end of the supporting opening, a threaded column is rotatably connected to the bottom end of the supporting opening, a top plate and a rubber plate are arranged at the top end of the threaded column, a pair of sliding columns is slidably connected into the pipe body, the side walls of the sliding columns are in interference fit with the inner wall of the pipe body, and the two sliding columns are connected through a connecting rod. A magnetic plate is connected to the connecting rod, a marking block is arranged on the pipe body, through grooves are formed in the end faces of the two sliding columns, arc-shaped grooves are formed in the sliding columns, arc-shaped plates are slidably connected to the interiors of the arc-shaped grooves, and electromagnets are installed at the inner ends of the arc-shaped grooves; according to the pipe body cutting-off device, a notch of a pipe body can be smoother, meanwhile, the situation that the pipe body is damaged during cutting is reduced, the effect of cooling the pipe body during cutting can be achieved, and the using effect of the cutting-off device is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cutting equipment, in particular to a cutting equipment for PVC pipes. Background technique [0002] PVC pipe rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. It is the earliest plastic pipe developed and applied. PVC-U pipe has strong corrosion resistance and is easy to use. Adhesion, low price and hard texture, but due to the exudation of PVC-U monomer and additives, it is only suitable for water supply systems with a conveying temperature not exceeding 45 °C, plastic pipes are used for drainage, waste water, chemicals, heating liquid and In the application of cooling liquid, food, ultra-pure liquid, mud, gas, compressed air and vacuum system, in the existing PVC pipe installation process, the construction personnel need to use tools to cut the length of the PVC pipe to facilitate the installation of the PVC pipe, but now ...
