Problems solved by technology

[0002] The traditional bellows expansion processing technology is complex, requires many workers, and has a low level of automation; in the production process of bellows, there are: the corrugation of the bellows is of different depths, the corrugation surface of the bellows is rough, and the corrugations on the bellows often appear Potholes not only affect the appearance of the product, but also make it difficult to guarantee the quality of the product; in the prior art, when the corrugated pipe is processed, the corrugated slope will appear, resulting in the production of waste corrugated pipe, which not only wastes social resources, but also increases the cost of enterprises. The production cost hinders the development of the enterprise

Abstract

The invention discloses a corrugated pipe expander which comprises a loading pressing head, a mold piece pressing plate, a forming mold piece, a mold piece base plate, a supporting seat, a drive rod, a loading oil cylinder, a rotating mechanism and a lifting workbench. The bottom of the loading pressing head is fixedly connected with one end of the drive rod, and the other end of the drive rod is fixedly connected with the output end of the loading oil cylinder. The rotating mechanism is arranged below the loading oil cylinder, and the loading oil cylinder penetrates through the face of the lifting workbench. The forming mold piece and the mold piece base plate are sequentially arranged below the mold piece pressing plate, and the mold piece pressing plate and the mold piece base plate are fixedly connected. The forming mold piece is connected with the loading pressing head through a connector. Operation of the whole machining process of the corrugated pipe expander is simple, and the reliability is good. Meanwhile, the loading pressing head drives the forming mold piece to rotate through the connector, corrugations on corrugated pipes are optimized, it is ensured that formed tube blanks are horizontally lifted through the lifting workbench, and the corrugations on the corrugation pipes do not tilt, so that the rate of finished corrugated pipes is improved.

Description

technical field [0001] The invention relates to the technical field of expanders, in particular to a bellows expander. Background technique [0002] The traditional bellows expansion processing technology is complex, requires many workers, and has a low level of automation; in the production process of bellows, there are: the corrugation of the bellows is of different depths, the corrugation surface of the bellows is rough, and the corrugations on the bellows often appear Potholes not only affect the appearance of the product, but also make it difficult to guarantee the quality of the product; in the prior art, when the corrugated pipe is processed, the corrugated slope will appear, resulting in the production of waste corrugated pipe, which not only wastes social resources, but also increases the cost of enterprises. The production cost hinders the development of the enterprise. Contents of the invention [0003] The object of the present invention is to provide a bellow...
