Aforesaid heat exchanger bender is characterized in that: described mandrel 5 is a cantilevered axle, and described lower tooth bar 4 is provided with can push down described mandrel 5 free-ended pinch rollers 8.
Aforesaid heat exchanger bender, it is characterized in that: described pushing mechanism 7 comprises the connecting rod 703 that upper end and described lower tooth bar 4 are hinged, described connecting rod 703 other ends are hinged with rocking arm 701, described rocking arm 701 middle parts and described crane 6 are hinged, and described rocking arm 701 lower ends are hinged with and promote its cylinder that waves 702.
Aforesaid heat exchanger bender is characterized in that: described crane 6 is provided with and drives the rotary cylinder 601 that mandrel 5 rotates.
Aforesaid heat exchanger bender is characterized in that: described drive unit 7 is chain wheel drive.
Aforesaid heat exchanger bender is characterized in that: also be provided with locating rack 9 in described left folding bent plate 2 one sides on the described frame 1.
Compared with prior art, the present invention has the following advantages:
1, the present invention first the micro-channel heat exchanger bending part is skewed the again bending that misplaces avoid causing pull pull open and the deformation direction consistent, improved product percent of pass.
2, pushing mechanism of the present invention is that a rocking arm promotes crane simultaneously and lower tooth bar moves, and crane and lower tooth bar are with advancing with moving back the coordinating and unifying.
