Pipe expanding clamping mechanism and pipe expanding machine with pipe expanding clamping mechanism

Abstract

The invention provides a pipe expanding clamping mechanism and a pipe expanding machine with the pipe expanding clamping mechanism. The pipe expanding clamping mechanism is arranged below an expandingrod hanging mechanism used for conducting pipe expanding operation on a metal pipe of a heat exchanger, and is used for clamping a heat exchange pipe of the heat exchanger. The pipe expanding clamping mechanism comprises a clamping beam arranged below the expanding rod hanging mechanism in a lifting manner, and a pipe body clamping assembly. The pipe body clamping assembly is arranged on the clamping beam and ascends and descends along with the clamping beam. The pipe body clamping assembly has a pipe body clamping state for clamping of the heat exchange pipe, and a pipe body releasing statefor releasing of the heat exchange pipe, and accordingly when the heat exchange pipe is clamped, an expanding rod of the expanding rod hanging mechanism penetrates the pipe body clamping assembly andstretches into the heat exchange pipe so as to conduct pipe expanding operation on the heat exchange pipe. The pipe expanding clamping mechanism solves the problem that a heat exchanger metal pipe machining manner in the prior art is low in efficiency.

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 ...
