A two-way stamping tube expander

Abstract

The invention discloses a bidirectional stamping tube expander. The bidirectional stamping tube expander comprises a machine frame body, an upper sliding rail and lower sliding rails, wherein horizontal supporting frames used for fixing a tube expanding tool are arranged on the left side and right side of the machine frame body respectively, traveling mechanisms are arranged at the left end and right end of the upper sliding rail respectively, the horizontal supporting frame on the left side of the machine frame body is movably connected with the lower end of the traveling mechanism at the left end of the upper sliding rail, and the horizontal supporting frame on the right side of the machine frame body is movably connected with the lower end of the traveling mechanism at the right end of the upper sliding rail; two working tables used for fixing a tube are arranged at the lower ends of the traveling mechanisms at the left end and right end of the upper sliding rail respectively, and each lower sliding rail is connected to the lower side of the corresponding working table. In this way, tube stamping and expanding can be achieved quickly, working efficiency is improved, and machining precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a bidirectional stamping tube expander. Background technique [0002] In the prior art, for the metal pipe parts with thin middle and thick structure at both ends, one of the processing methods is welding, which is directly connected with the small pipe and the large pipe; Metal pipe parts with thin middle and thick structures at both ends have a long manufacturing process. Usually, after expanding the pipe at one end manually, the other side is completed. Multiple positioning of the parts will cause a very large coaxiality error, which cannot meet the accuracy requirements. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a two-way punching tube expander, which can quickly punch and expand tubes, improve work efficiency, and ensure processing accuracy. [0004] In order to solve the above technical ...
