Problems solved by technology
[0002] Internal high pressure forming is a technology for high-pressure forming of complex characteristic curved surfaces of pipe and plate parts through high-pressure liquid in the mold cavity; when in use, the cylinders on the left and right sides of the hydraulic press push the push heads to the left and right ends of the mold for sealing Liquid-filled forming, so the internal high-pressure forming process cannot be realized in the processing of large-diameter pipes, but there is currently a lack of internal high-pressure forming devices for processing stainless steel pipe fittings

The invention discloses a thin pipe forming device and method. The thin pipe forming device comprises a die body and floating cylinders, the die body is divided into an upper die and a lower die, the upper die and the lower die are each provided with a forming cavity, and the upper forming cavity corresponds to the lower forming cavity; the two floating cylinders are arranged at the left end and the right end of the forming cavity in a sliding mode respectively, a liquid filling exhaust channel is arranged in one floating cylinder, a pipe is arranged in the forming cavity of the lower die, the upper die and the lower die are combined, the floating cylinders abut against the two ends of the pipe, the floating cylinders exert constant force on the pipe, and the pipe is kept static and does not deform. And high-pressure liquid is filled into the pipe, so that the pipe expands and deforms, and the expansion rate is increased.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a thin pipe forming device Background technique [0002] Internal high pressure forming is a technology for high-pressure forming of complex characteristic curved surfaces of pipe and plate parts through high-pressure liquid in the mold cavity; when in use, the cylinders on the left and right sides of the hydraulic press push the push heads to the left and right ends of the mold for sealing Liquid-filled forming, so the internal high-pressure forming process cannot be realized in the processing of large-diameter pipes, but there is currently a lack of internal high-pressure forming devices for processing stainless steel pipe fittings. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, according to the embodiment of the first aspect of the present invention, a th...
