The invention discloses a metal thin wall double-layered tube impact hydro-bugling device. The device comprises a die holder device which is located on a lower die seat of a press machine and is composed of a positioning die holder and a lower die which is installed in the positioning die holder; the positioning die holder comprises a sliding mechanism, a lower die holder and an upper die holder; the sliding mechanism comprises a sliding seat, a horizontal sliding block, a horizontal guide column and a lead screw, a non-threaded segment of the lead screw penetrates out of two ends of the lower die holder and is fit with a lead screw driving mechanism in a transmission mode, the upper die holder is arranged on the lower die holder and is in a liquid storage container shape, the lower die is arranged on the bottom of a liquid storage container, the horizontal guide column arranged on the horizontal sliding block penetrates through two ends of the upper die holder, the horizontal guide column and the axis of a metal thin wall double-layered tube to be machined are coaxial, and liquid of the double-layered tube is sealed. By means of the device, metal thin wall double-layered tube impact hydro-bugling expansion is simple, convenient and easy to conduct, the hydraulic expansion efficiency is high, and the quality is reliable and guaranteed.
Description
technical field [0001] The invention relates to a metal pipe hydraulic bulging technology, in particular to a metal thin-walled double-layer pipe impact hydraulic bulging method and device. Background technique [0002] Metal tube hydraulic bulging is a forming technology that plastically deforms metal tubes through internal pressure and fits them with molds. Metal tube hydraulic bulging technology has the advantages of simple process, less process, high material utilization rate, high part rigidity and light weight. It has been more and more widely used in automobile, aerospace, aviation, home appliance and construction industries. However, at present, to achieve hydraulic bulging of metal tubes, a special internal pressure source must be used to provide high pressure inside the tube. Therefore, the equipment for hydraulic bulging of metal tubes is relatively large and costly. The popularization and application of hydraulic bulging technology for metal tubes has brought Gr...
