Abstract

The invention discloses a double-station corrugated pipe hydraulic forming machine. The double-station corrugated pipe hydraulic forming machine comprises a machine frame. A left die frame, a right die frame, a lower die head dragging plate, two die heads, an oil feeding pipe, a left die piece, a left spiral insertion piece, a right die piece, and a right spiral insertion piece are arranged on the machine frame. The left spiral insertion piece and the right spiral insertion piece are arranged oppositely. A die disassembly and assembly hydraulic cylinder and a die separation piece hydraulic cylinder are arranged behind the machine frame from top to bottom. The die disassembly and assembly hydraulic cylinder is connected with the left die frame and the right die frame through connecting rods. The die separation piece hydraulic cylinder is connected with the left spiral insertion piece and the right spiral insertion piece. A pressing hydraulic cylinder is arranged above the left die piece and the right die piece. A pressing column is arranged below the pressing hydraulic cylinder. A pressing block is arranged at the bottom of the pressing column. A latch hook device is arranged on the left die frame, and the latch hook device is connected with the right die piece. The invention further discloses a realizing method of the double-station corrugated pipe hydraulic forming machine. The double-station corrugated pipe hydraulic forming machine and the realizing method of the double-station corrugated pipe hydraulic forming machine have the characteristics that the structure is simple, the manufacturing cost is low, the labor intensity is low, the production efficiency is high, the product quality is good, and the qualified rate is high.

Description

technical field [0001] The invention relates to the production technology of corrugated pipes, in particular to a double-station corrugated pipe hydraulic forming machine and its realization method. 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. [0003] In the prior art, when the corrugated pipe is pressed and formed, single-head hydroforming is used, and only one product can be completed at a time of hydraulic pressure, and the same-direction mold splitting technology is adopted, so the following technical problems exist in the prior art: [0004] (1) High labo...
