Bellows Forming Mechanism

Abstract

The invention discloses a corrugated pipe forming mechanism, which is arranged behind the discharge end of the corrugated pipe mould. unit, the water cooling assembly is located inside the module assembly, the bellows is formed between the inner wall of the module assembly and the outer wall of the water cooling assembly, the air blowing assembly includes a gas splitter, an air outlet space formed between the bellows mold and the water cooling assembly, and the air outlet space There are gas outlets in the circumferential direction. The gas distributor has an air inlet joint and a plurality of air outlet joints connected with the air inlet joint. Each air outlet joint is provided with an air pressure regulating valve, and each air outlet joint is connected to the air outlet space. The air pressure can be adjusted independently through each air pressure regulating valve, so that the circumferential air blowing air pressure is the same, ensuring the regularity of the shape of the bellows flared part, improving the performance of the product, simple in structure, easy to install, and suitable for popularization and use.

Description

technical field [0001] The invention relates to a bellows forming mechanism. Background technique [0002] The bellows forming mechanism generally includes three parts: module assembly, water-cooling assembly and air blowing assembly. The bellows includes a normal corrugated part and a flared part for insertion. During the forming process of the flared part, only the vacuum in the module The function cannot make the material stick to the inner wall of the module component well, so the assistance of the blowing component is needed. The original blowing component only has one air outlet joint, so that the air pressure corresponding to the position of the air outlet joint is relatively large, and other parts The air pressure is small, the air pressure of each part in the circumferential direction is not equal, and the flaring part is formed irregularly, which makes the subsequent plug-in installation difficult and seriously affects the performance of the product.

Problems solved by technology

[0002]The bellows forming mechanism generally includes three parts: module assembly, water cooling assembly and air blowing assembly. In the molding process of the mouth part, the vacuum effect in the module component alone cannot make the material adhere to the inner wall of the module component well, so the assistance of the blowing component is needed. The original blowing component only has one outlet The air pressure at the position corresponding to the air outlet joint is relatively large, the air pressure in other parts is small, the air pressure in various parts in the circumferential direction is not equal, and the flaring part is formed irregularly, which makes it difficult to insert and install later, which seriously affects the performance of the product.
