Embodiment Construction

[0025] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] like figure 1 , image 3 As shown, the high-efficiency cooling device used for pipeline production includes a sizing sleeve 1 and a die 2 coaxially arranged at intervals along the horizontal direction. There is an annular air knife-3 for sheathing on the periphery of the tube embryo. The annular air knife-3 can be fixed to a specified height through the support structure on the ground. The air outlet of the annular air knife-3 is set on the side where the sizing sleeve 1 is located. , that is, the annular conical airflow formed by the annular air knife-3 flows toward the side where the sizing sleeve 1 is located. The material forms a tube embryo after passing through the die 2. The tube embryo is drawn and pre-coo...

Abstract

The invention provides an efficient cooling device for pipeline production, and belongs to the technical field of pipe fitting production equipment. The technical problem that an existing pipeline cooling device possibly affects the pipe fitting forming effect is solved. The efficient cooling device for pipeline production comprises a sizing sleeve and a mouth mold which are coaxially arranged at intervals in the horizontal direction, a first annular air knife used for being arranged on the periphery of a pipe blank in a sleeving mode is arranged between the sizing sleeve and the mouth mold, and an air outlet of the first annular air knife faces the side where the sizing sleeve is located. Deformation of the pipe blank can be controlled, and the forming effect of the pipe blank is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pipe fitting production equipment, and relates to a high-efficiency cooling device for pipe production. Background technique [0002] Due to the viscoelasticity of polymers, under the action of force, there will be relative slippage between the molecular chains, that is to say, the tube embryo will be deformed when it is subjected to gravity, so the tube embryo should be cooled and shaped immediately after leaving the die. The cooling and setting effect of the pipe directly affects the production efficiency of the pipe. [0003] The Chinese patent application publication number CN108394082A discloses a polyethylene pipe extrusion cooling device, which includes a water tank and a cooling calibrating sleeve. A spray cooling ring is installed in the middle, and the spray cooling ring is connected with the water inlet pipe, and a booster pump is arranged on the water inlet pipe, and an annular air cooling ri...
