Abstract

The invention provides an expansion pipe clamping mechanism and a pipe expander provided with the same. The expansion pipe clamping mechanism is arranged below an expansion rod hanging mechanism whichis used for conducting pipe expansion operation on metal pipes of heat exchangers, and the expansion pipe clamping mechanism is used for clamping heat exchange pipes. The expansion pipe clamping mechanism comprises a clamping transverse beam, a pipe body clamping assembly and a clamping driving assembly, wherein the clamping transverse beam can go up and down and is arranged below the expansion rod hanging mechanism; the pipe body clamping assembly is installed on the clamping transverse beam, goes up and down along with the clamping transverse beam, has a pipe body clamping state used for clamping the heat exchange pipes and a pipe body release state used for release the heat exchange pipes so that when the heat exchange pipes are clamped, expansion rods can penetrate through the pipe body clamping assembly and then stretch into the heat exchange pipes to conduct pipe expansion operation on the heat exchange pipes; and the clamping driving assembly is connected with the pipe body clamping assembly, so that at least part of the pipe body clamping assembly is driven to move, and the pipe body clamping assembly is in the pipe body clamping state or the pipe body release state. According to the expansion pipe clamping mechanism and the pipe expander provided with the same, the problem that in the prior art, the mode for machining metal pipes of heat exchangers is low in efficiency is solved.

Description

technical field [0001] The invention relates to the field of heat exchanger processing, in particular to a tube expander clamping mechanism and a tube expander with the same. Background technique [0002] In the production process of the heat exchanger, it is necessary to closely combine the metal tube and the fins fitted on it, so as to ensure good heat transfer and conduction, and it is light in weight and has a long service life. [0003] At present, the method that people adopt is to manually insert the expansion rod with the ball head into the metal pipe to expand the metal pipe, and then draw out the expansion rod. Only one pipe can be expanded at a time, which is labor-intensive and low in production efficiency. And it is very difficult to expand the metal tubes of large-scale heat exchangers, and there is an urgent need for a tube expander that can have multiple metal tubes at one time and is convenient for expanding the metal tubes of large-scale heat exchangers to ...
