A kind of plastic bellows forming processing method

Abstract

The invention relates to a plastic corrugated pipe forming machining method. The method mainly comprises the following steps: mixing and stirring, heating and drying, forming treatment, cooling forming, grain cutting, cutting operation and the like; and used corrugated pipe grain cutting equipment comprises a bottom plate, a rotating device, a clamping device and an abutting device. The followingproblems that during existing in existing corrugated pipe grain cutting, a, a production technology of traditional corrugated pipe manufacturing equipment is not mature enough, the operation is not stable enough, the grain quality of a corrugated pipe is seriously influenced, the corrugated pipe can only be manufactured through turning, but the wall thickness of the manufactured corrugated pipe isnot uniform easily due to the existing turning mode, and the service life of the corrugated pipe is shortened; and b, a traditional corrugated pipe forming machine is single in forming specification,the depth of corrugations on a pipe is low in the forming process, and the requirements in actual work cannot be met can be solved, corrugated pipe grains can be evenly and stably cut, and the production quality of the corrugated pipe is improved.

Description

technical field [0001] The invention relates to the technical field of corrugated pipe manufacturing and processing, in particular to a plastic corrugated pipe forming and processing method. 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, the wall of the bellows is thinner, the sensitivity is higher, and the measurement range is tens of Pa to tens of MPa. When the plastic bellows are manufactured, the lines of the bellows need to be refined. [0003] However, the following problems exist in the existing corrugated pipe pattern cutting, a. The structure of the traditional corrugated pipe manufacturing equipment is too complicated, and its operation is to...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the existing corrugated pipe pattern cutting, a. The structure of the traditional corrugated pipe manufacturing equipment is too complicated, and its operation is too complicated during the production process, and it is difficult for employees to accurately control it The production technology of the existing equipment is not mature enough, and its operation is not stable enough, which seriously affects the texture quality of the bellows. It can only be made by turning, but the current turning method is easy to cause the wall thickness of the bellows to be uneven, shortening the corrugation. The service life of the pipe; b, the traditional corrugated pipe forming machine has a relatively single forming specification, and the depth of the corrugation on the pipe is low during forming, which cannot meet the needs of actual work, and can uniformly and stably cut the corrugated pipe lines operation, improving the production quality of bellows
