The invention discloses a metal thin-wall pipe impact hydraulic bulging system. The system includes an upper workbench and a lower workbench. An upper mold is installed in the middle of the lower part of the upper workbench, and both sides of the upper mold have oblique sliders fixed on both ends of the upper workbench. A positioning formwork is fixed above the lower workbench. A liquid container is arranged in the middle of the positioning formwork. Side doors are provided on the side of the liquid container. There is a lower mold for axially installing the metal thin-walled tube in the liquid container. The two sides of the lower mold are useful. To withstand the horizontal guide pillars at the two ends of the metal thin-walled pipe. The outer end of the horizontal guide column is provided with an anti-rotation slide block, a linear bearing and a return spring. The system does not need a special internal pressure source, is simple and easy to operate, and has high hydraulic bulging efficiency. During the impact bulging process, automatic axial feeding of metal thin-walled tubes can be realized to prevent local thinning of metal thin-walled tubes. In order to form metal thin-walled tubes of different shapes, it can be realized only by changing the upper and lower molds, and the operation is simple, the structure is simple, and the cost is low.
Description
technical field [0001] The invention relates to the hydraulic bulging technology of metal thin-walled pipes, in particular to an impact hydraulic bulging system of metal thin-walled pipes. Background technique [0002] Hydraulic bulging of thin-walled metal pipes is a forming technology that plastically deforms thin-walled metal pipes through internal pressure and fits them with molds. Metal thin-walled 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 industries such as automobile, aerospace, aviation, home appliances and construction. [0003] At present, the hydraulic bulging of metal thin-walled tubes can be achieved by using a special internal pressure source to provide high pressure inside the tube, but the equipment is relatively large and the cost is high. It can also be filled with liquid containers, such as the patented [...
