Abstract

The invention relates to a tube drawing machine, the lower end of a housing is connected with a motor through a bolt connection pad, a driving wheel is radially arranged in a cavity of the housing, asliding support is arranged on the right side of the inner cavity of the housing, a driven wheel is radially arranged therein, a base pillar is fixedly arranged at the right end of the sliding support, a transition sleeve is sheathed on the right side of a shaft shoulder of the base pillar, a thrust bearing, a disc spring and guide sleeves are sequentially arranged on the transition sleeve, the end part of the right side of the base pillar passes through a screw and a handwheel, a screw rod is arranged in the inner cavity of the base pillar, the spring is sheathed on the outer wall of the screw rod, inclined through holes are formed on the front end surface and the back end surface of the housing, and the front guide sleeve and the back guide sleeve are fixedly arranged in the through holes. The tube drawing machine has the advantages of compact structure, reasonable design, full utilization of principles of friction force, rapid tube drawing speed and high efficiency.

Description

technical field [0001] The invention is suitable for extracting stuck old tubes during the tube exchange process of various heat exchangers. Background technique [0002] At present, in the process of replacing the old tubes of the heat exchanger with new tubes, after the old tubes are pulled out of the tube heads, most of them are pulled out manually one by one. Time-consuming, difficult to operate, extremely low efficiency. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages in the above-mentioned technology, and provide a pipe extractor with compact structure and reasonable design, which can extract the jammed pipe from the condenser under the action of friction. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: the lower end of the housing is connected to the motor through a bolted backing plate, the driving wheel is radially installed in the housing cavity, a...
