Cooling equipment for PVC pipeline punching

Abstract

The invention discloses cooling equipment for PVC pipeline punching. The cooling equipment comprises a worktable, cooling water tanks are fixedly connected to the two sides of the worktable correspondingly, water pumps are fixedly connected to the tops of the cooling water tanks, the water outlet ends of the water pumps communicate with Y-shaped hoses, and water outlets of the Y-shaped hoses communicate with a hard guiding pipe; the water outlet end of the hard guiding pipe is fixedly connected with a spraying head, wherein the spraying head comprises a pipe seat, a fixing sleeve, a spraying pipe and a water spraying cover plate; the pipe seat is detachably connected to the water outlet end of the hard guiding pipe through a plurality of clamping-connection assemblies, the fixing sleeve isarranged on the periphery of a spherical shell of the pipe seat in a sleeving mode, the spraying pipe is fixedly connected with the fixing sleeve to form an external spraying piece, and the sprayingpipe is limited on the periphery of the spherical shell by the fixing sleeve; and the water spraying cover plate is arranged at the water outlet end of the spraying pipe. By adopting the structure, the cooling equipment can effectively cool a PVC pipeline, and the quality of the PVC pipeline is improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a cooling device for punching PVC pipes. Background technique [0002] Among non-metallic pipelines, plastic pipes are the most widely used. There are many types of plastic pipes, which are divided into two categories: thermoplastic pipes and thermosetting plastic pipes. There are thermoplastic pipes, such as polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, polyoxymethylene pipes, etc.; there are phenol plastic pipes that are thermosetting. Plastic pipes have the advantages of good corrosion resistance, light weight, convenient molding, and easy processing. Therefore, plastic pipes have been more and more widely used in construction projects. During the processing of plastic pipes, sometimes it is necessary to punch plastic pipes. Hole processing, due to the low melting point of plastic pipes, the temperature is too high during the drilling process,...

Problems solved by technology

[0004] The water sprayed by the nozzle in the above-mentioned patent documents cannot be fully sprayed to the incision between the drill bit and the punched workpiece, so the cooling effect is not good. In addition, the nozzle is fixedly connected to the hard conduit. When the nozzle is damaged, the nozzle cannot be sprayed. Replacement separately wastes resources and shortens the service life of the entire device
