Description
(1) technical field
The present invention relates to the expander roll selecting arrangement of electric tube expander.
(2) background technology
The Main Function of electric tube expander in heat exchanger production process is to expand the diameter of copper pipe, make copper pipe withRadiating fin close contact, avoids producing loosening and increase heat conductivility. On every electric tube expander, allow peaceLoad onto hundred expander rolls, and the length of every expander roll is generally long at 2-3 rice, the radiating fin of different heat exchangersInterior copper pipe quantity there are differences, and for same electric tube expander, different heat exchangers is added to man-hour, needsIncrease or reduce expander roll, make the quantity of expander roll corresponding with the quantity of copper pipe. In prior art, thisIncrease or reduce the operation of expander roll, general employing increase manually the quantity of expander roll or unload unnecessaryExpander roll, the artificial manual mode of such use has increased operation easier, and inefficiency.
For the problem that operates manually existence, in prior art, also proposed to adopt automatically and change and selectThe device of expander roll, is called " a kind of electric tube expander in the disclosed name of Chinese invention patent CN201320683116Expander roll selecting arrangement ", adopt automatic technology to replace manually behaviour, increase work efficiency. But its, in use there are a little problems in structure Shortcomings: the central shaft of push rod and the central shaft of bearing pinDecentraction, has caused stirring while selecting the push rod of piece at pulling mechanism thus, selects that piece can be around bearing pinCentral shaft rotates to have realized blocking position and fallen through and switches between position, but selects piece also likely can be liftedPlay or press down and caused being stuck (or be called suppress) in storage tank and can not automatically select expander roll.Therefore there is improved necessity in this structure.
