Description
Technical field
The utility model is related to a kind of utilization compressed air carries out the device of tube expansion.
Background technology
The tube expansion of existing electric tube expander is all mechanical tube expansion, i.e., by will expander roll be pressed into metal tube in make which swell so as to
Heat exchanger fin is combined closely, to strengthen the rate of heat exchange of heat exchanger.Electric tube expander complex structure needed for this mechanical tube expansion,
Fault rate is high, and mechanical tube expansion carries out tube expansion by swollen head to the squeezing action of inside pipe wall, easily causes the damage of inside pipe wall, institute
Also affected with product rejection rate higher energy efficiency ratio；The expander roll of mechanical tube expansion is longer so that the height of electric tube expander is higher, right
The height of factory building there are certain requirements；And overall heat exchange device workpiece be soldered after can just carry out the leak detection in later stage, if hunting leak out
It is that long U pipes have leak source, then the operation carried out after tube expansion will be idle work, wasting manpower and material resources.
Content of the invention
Technical problem to be solved in the utility model is to overcome the drawbacks described above of prior art and provide a kind of tube expansion height
Calm the anger the electric tube expander of cubical expansion pipe so as to simple structure, pipe fitting will not be damaged.
The utility model solve the technical scheme that adopted of above-mentioned technical problem for：
A kind of air electric tube expander, solid including frame, base, power seat, power seat drive mechanism, air bulking mechanism, workpiece
Determine component, compressed gas source；The frame is fixed on base, and power seat is fixed in two side of frame, and power seat is by power seat driving machine
Structure drives and moves up and down, and air bulking mechanism is fixed in power seat, and air bulking mechanism includes several expansion cores, arranges empty in expansion core
Gas passage, compressed gas source are connected with expansion core air duct, and workpiece fixation kit is arranged on base.
Preferably, above-mentioned air bulking mechanism also includes that installing plate, expansion core installing plate, distribution plate, expansion core are pacified installed in expansion core
On dress plate, expansion core installing plate top is fixed with installing plate, and side is connected with distribution plate, arranges air duct, air in distribution plate
Passage is communicated with several expansion cores, and compressed gas source is communicated with distribution plate air duct, is distributed compressed air by distribution plate, is more held
Easily manufacture.
Preferably, necking seat is also set up, and outside expansion core, cover plate is covered outer in necking seat and is fixed on expansion core installation necking cover for seat
On plate, so more with great difficulty install.
Preferably, spacer is also set up, and spacer is enclosed between necking cover for seat and expansion core.
The utility model can reduce the damage of inside pipe wall due to carrying out tube expansion by air, eliminate pipe with fin contacts not
Uniform possibility, so that greatly promote Energy Efficiency Ratio；And using air tube expansion without the need for expander roll, it is possible to decrease the height of electric tube expander,
Simplify electric tube expander structure, so as to reduce factory building height, area occupied is little；Can also find that during tube expansion the leakage of tubing is asked
Topic, the leak detection link early rather than after welding find, so as to time-consuming and cost of labor.
