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 great inconvenience

[0021] Embodiment of metal thin-walled pipe impact hydraulic bulging device
[0022] Examples of the metal thin-walled tube impact hydraulic bulging device Figures 1 to 3 As shown, the outer diameter of the liquid supply bolt 9 is smaller than the metal thin-walled tube 7 to be formed, and the length is longer than that of the metal thin-walled tube 7. The diameter of the middle section of the liquid supply bolt 9 is greater than the diameter of the left and right sections, and its outer wall forms a step. The two ends of the liquid supply bolt 9 have external threads, each of which has a central blind hole, and the bottom end of the blind hole communicates with the outer wall of the liquid supply bolt 9 through a radial hole, and the radial hole opening is on the outer wall of the middle section. The liquid supply bolt 9 passes through the metal thin-walled tube 7, and both ends extend out of the metal thin-walled tube 7. The radial hole of the blind hole at one end connecti...

The invention relates to an impact hydraulic bulging device for thin-walled metal tubes and a method for using the same. The bottom ends of the central blind holes at both ends of the liquid supply bolt communicate with the outer wall through radial holes. The liquid supply bolt passes through the metal thin-walled pipe and protrudes from both ends, and the sealing plug sleeve is inserted into the nozzle of the metal thin-walled pipe at both ends of the liquid supply bolt. The large hole in the stepped hole in the center of the positioning cover is set on the nozzle of the metal thin-walled pipe, the liquid supply bolt protrudes from the small hole, the nuts are screwed into both ends of the liquid supply bolt, and the positioning cover squeezes the sealing plug to fit the metal thin-walled pipe and the liquid supply bolt. One end of the liquid supply bolt is connected to the L-shaped pipe through the control valve, and the other end is sealed to the liquid container through another control valve. The upper and lower templates of the formwork respectively fix the upper and lower molds, and the metal thin-walled tube is placed between the upper and lower molds. The method of use is to open the left and right control valves, pour into the liquid container to fill the metal thin-walled tube with liquid, close the control valve, press the punch head down, and close the upper and lower molds to realize hydraulic bulging. The invention is simple and easy to implement, high in efficiency, simple in structure and low in cost.
Description
technical field [0001] The invention relates to a metal tube hydraulic bulging technology, in particular to a metal thin-walled tube impact hydraulic bulging device and a use method thereof. 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 G...
