An ultra-slender bellows forming device

Abstract

The invention discloses an ultra-slender corrugated pipe forming device, comprising a workbench, a hydraulic drive mechanism, a lower pressing plate and a forming die are arranged on the workbench, and die side pushing cylinders are arranged on both sides of the forming die. The forming die includes an upper die and a lower die; the upper die and the lower die form a bellows forming die channel with a number of forming areas in the middle after the upper and lower dies are attached, and two sides of the bellows forming die channel are respectively set. There is a hydraulic side cylinder, and the hydraulic side cylinder is connected with a plunger rod that can be inserted into the bellows forming die channel. One side of the outer end is provided with a plug connected to the liquid injection mandrel. The invention has the advantages that the ultra-slender stainless steel bellows required by the water distribution system can be manufactured in large quantities and efficiently, and the customized processing of the stainless steel bellows can be realized.

Description

technical field [0001] The invention relates to the technical field of bellows forming, in particular to an ultra-slender bellows forming device. Background technique [0002] At present, the vast majority of water distribution systems in my country are mostly connected by plastic pipes or carbon steel pipes. In some developed countries and regions, stainless steel bellows have been gradually used to replace the original plastic pipe or carbon steel pipe connection in the water distribution system. Because the stainless steel corrugated pipe has the characteristics of corrugated vibration reduction and easy bending, replacing plastic pipes with corrugated pipes can reduce a large number of joints, which is more convenient and reduces the risk of dripping. In addition, the stainless steel bellows has a good resistance to external forces, can effectively prevent damage from external forces, and has a longer service life. [0003] The stainless steel bellows in the water dist...

Problems solved by technology

Due to the thin, long, and multi-corrugated stainless steel bellows in the water distribution system, these characteristics are not found in conventional bellows products. In actual production, the position and number of corrugated sections often need to be flexibly changed to meet different environments. The processing of stainless steel bellows of this size is very difficult. If a conventional bellows hydraulic forming machine is used, even if the hydraulic forming machine is reduced in proportion, it will encounter obstacles in the length of the bellows. The internal high-pressure hydraulic press is especially It will face the serious problem of high oil temperature in the hydraulic system, and it cannot be used to manufacture the stainless steel bellows required in the water distribution system
