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.
