Pipe diameter adjustable PVC pipeline flaring machine

Abstract

The invention provides a pipe-diameter-adjustable PVC pipeline flaring machine, and relates to the technical field of PVC, the pipe-diameter-adjustable PVC pipeline flaring machine comprises a box body, a moving block and a heating assembly arranged on the moving block and used for heating a PVC pipeline, a workbench is fixedly installed in the box body, the moving block is arranged at the top of the workbench, an extrusion block is fixedly connected to one side of the moving block, and the extrusion block is fixedly connected to the other side of the moving block; an adjusting plate is arranged at the top of the workbench, and a pressing assembly used for fixing the PVC pipe is arranged in the box body. According to the flaring machine, through cooperative use of a heater, an electric heating coil, an air blower, a heat dissipation pipe and a heat conduction piece, the extrusion block can be heated while the pipe opening part of a PVC pipeline is heated and softened, the situation that flaring operation is affected due to cold shrinkage of the PVC pipeline is avoided, and through cooperative use of an adjusting plate, an adjusting block, a check block and the extrusion block, the PVC pipeline is not prone to falling off. The relative position of the PVC pipeline and the extrusion block can be adjusted according to the diameter of a pipe opening needing to be expanded, and adjustment of pipe diameters of different sizes is completed.

Description

technical field [0001] The invention relates to the technical field of PVC, in particular to a PVC pipe belling machine with adjustable pipe diameter. Background technique [0002] PVC is the abbreviation of PVC, the main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, and ductility. PVC pipes have strong corrosion resistance, easy bonding, low price, hard texture, etc. Features Commonly used in drainage, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. [0003] When PVC pipes are connected to extension pipes, they are generally connected by sockets. Therefore, the diameters of the two ends of the PVC pipes are different, and one end of the PVC pipes needs to be flared so that one end of the PVC pipes can be connected with the other PVC pipes are socketed, so it is necessary to use a PVC pipe flaring machine to perform flaring operatio...

AI Technical Summary

Problems solved by technology

[0004] When performing flaring processing on PVC pipes, it is necessary to heat up the PVC pipe first to soften the mouth of the pipe, and then pass the softened mouth of the pipe through the flaring machine for flaring operations, and due to the extrusion of the flaring machine The temperature of the block is low, which leads to the high temperature PVC pipe nozzle being in contact with it, which is easy to shrink due to cold and affects the flaring efficiency. Nowadays, PVC pipes are used in various fields, which leads to the need to sleeve PVC pipes of different sizes. At this time, it is necessary to expand the nozzle of the PVC pipe to different sizes according to the different use environments, and the existing flaring machine can only expand the PVC pipe to a single size during the process of flaring the PVC pipe. If you need to change the expanded size, you need to replace the extrusion block, which is very troublesome and cannot meet the diverse needs of today
