An inclined plastic bellows extrusion inner forming device

Abstract

The invention relates to the technical field of plastic corrugated pipes, in particular to an inclined plastic corrugated pipe extruding inner forming device. The technical problem to be solved by the present invention is to provide an inclined plastic bellows extruding inner forming device. An inclined plastic bellows extruding inner molding device, including a support frame and a fixed base, etc., the left and right parts of the bottom end of the support frame are welded to the fixed base; Carry out separate synchronous addition, and then indirectly link the inclined corrugated inner forming mechanism pipe to perform inclined rotary extrusion and closed corrugated extrusion to make the extrusion more balanced, and then through the omni-directional rotating cooling mechanism to cool the corrugated plastic pipe Carry out all-round rotation cooling to form a spiral airflow on the surface, accelerate the cooling of the plastic pipe, and realize the effects of full pre-mixing of plastic raw materials, inclined extrusion, internal corrugation rotation forming, and omni-directional rotation cooling.

Description

technical field [0001] The invention relates to the technical field of plastic corrugated pipes, in particular to an inclined plastic corrugated pipe extruding inner forming device. Background technique [0002] Plastic bellows refers to a tubular elastic sensitive element made of foldable corrugated sheets made of plastic connected along the direction of folding and expansion. Bellows are widely used in instruments and meters. The main purpose is as a measuring element for pressure measuring instruments to convert pressure into Displacement or force, although the wall of the bellows is thin, the sensitivity of the bellows is high, the measuring range of the bellows is tens of Pa to tens of MPa, the open end of the bellows is fixed, the sealed end is in a free state, and the The auxiliary coil spring or reed increases the elasticity. When working, it will elongate along the length of the pipe under the action of internal pressure, so that the movable end will have a displace...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the problems in the prior art that the plastic raw materials cannot be fed at the same time when adding, the mixing time is long, the stirring is uneven, the heating and smelting is not thorough, the horizontal extrusion causes too many bubbles on the wall of the bellows, and the internal structure is not tight. Due to the shortcomings of shortened life, large amount of water consumption for cooling, and environmental pollution, the technical problem to be solved by the present invention is to provide an inclined plastic bellows extrusion inner forming device
