Abstract

The invention discloses thin-wall corrugated pipe machining equipment. The equipment comprises a base; a frame is installed above the base; a guide rod is installed on the inner side of the frame; a sliding die and a fixed die are connected to the guide rod in a sleeving mode, and are each provided with a second hydraulic cylinder; and a front die piece and a rear die piece are arranged in each ofthe sliding die and the fixed die, and the front die piece and the rear die piece are connected with a mounting block. The equipment is simple in structure; a blank tube is sleeved with one end of ahigh-pressure water pipe, the two front die pieces and the two rear die pieces clamp the blank tube under the action of the second hydraulic cylinders, a first hydraulic cylinder drives the sliding die to slide towards the fixed die, and the blank tube is wrinkled; meanwhile, the water pump injects water into the high-pressure water pipe and sprays the water out from a water outlet hole, so that the folds of the blank tube are stressed uniformly, the surface of the expansion position of the blank tube is round, the front die pieces are separated, the sliding die is retracted, the front die pieces clamp the blank tube again, the sliding die moves forward, and through repeatedly carrying out the operation, the corrugated pipe can be continuously machined.

Description

technical field [0001] The invention relates to the technical field of corrugated pipes, in particular to a thin-walled corrugated pipe processing equipment. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. Bellows are widely used in instruments and meters, and their main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. [0003] When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end driv...
