The metal thin-walled double-layer pipe impact hydraulic bulging device of the present invention includes a mold base device consisting of a positioning mold base and a lower mold installed in the positioning mold base located on the lower mold base of the press, and the positioning mold base includes a sliding mechanism, The lower mold base and the upper mold base; the sliding mechanism includes a sliding seat, a horizontal slider, a horizontal guide column and a screw rod, and the non-threaded section of the screw rod passes out of the two ends of the lower mold base, and cooperates with the driving mechanism of the screw rod , the upper mold base is placed on the lower mold base to form the shape of the liquid storage container, the lower mold is placed on the bottom of the liquid storage container, the horizontal guide post on the horizontal slider passes through the two ends of the upper mold base and is connected with the thin-walled metal to be processed. The tube axes are coaxial, and are used to seal the liquid in the inner tube of the double-layer tube. Using the bulging device of the present invention to perform impact hydraulic bulging of metal thin-walled double-layer pipes is simple and easy, and the hydraulic bulging efficiency is high and the quality is 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...
