The center of cylinder offers the fin channels through engine base, and the engine base is equipped with for driving the orientation adjustment cylinder relative to machine
Seat rotates so as to have the driving mechanism of opposite placing direction by two adjacent fins of fin channels.
Driving mechanism drives the rotation of orientation adjustment cylinder, so that the angle of fin channels changes, this allows for leading to
Crossing the fin of fin channels can put under the action of after leaving fin channels in inertia force towards different directions, pass through control
The angle change size of fin channels may be implemented to put fin " a positive and a negative ", so that subsequently being capable of wing
Piece is placed into a manner of " a positive and a negative " in the gap between the adjacent flat tube of micro-channel heat exchanger, after brazed, " one positive one
The fin stress being soldered to instead " on micro-channel heat exchanger can cancel out each other, and avoid diagonal line bad, and it is qualified to improve product
Rate.
Preferably, orientation adjustment cylinder periphery carries handle, the driving mechanism is the cylinder being hinged on engine base,
The piston rod of the cylinder is hinged with the handle；
The piston rod has that the origin that is contracted in cylinder, stretches out cylinder make that handle is rotated by 90 ° relative to origin
One working position and again contraction and stretches out cylinder make handle relative to the second working position of the first working position rotation 180 degree.
Handle is the equal of the torque of orientation adjustment cylinder, and after handle is arranged, piston rod can more easily drive orientation
Adjusting cylinder is rotated.
Before starting the work, piston rod is in origin (handle is in a straight line with piston rod at this time)；It starts to work
Afterwards, piston rod compression downlink, drives handle to be rotated by 90 ° relative to origin, and piston rod goes downwards to maximum distance, in the at this time
One working position, fin are put with " just " position；Then cylinder pressure disappears, piston rod uplink, and handle is driven to return to origin, used
Under the action of property power, handle will not rest on origin after reaching origin but can rotate a certain angle in the opposite direction；
Piston rod is pressurized downlink again at this time, then handle can continue to rotate in the opposite direction until relative to first under piston rod promotion
Working position rotates 180 degree, and piston rod goes again downwards to maximum distance, is in the second working position at this time, and fin is put with negation position
It puts；Piston rod is converted during contraction-elongation, successively between the first working position and the second working position so that fin with
The mode of " a positive and a negative " is put neatly.
Preferably, the middle part of the cylinder is hinged with the engine base, air inlet pipe is connected at the top of the cylinder.And
Piston rod can freely stretch.
Preferably, the end of the piston rod is fixed with extending sleeve, the extending sleeve is hinged with the handle.
In the utility model, around the fin channels, it is further opened on the orientation adjustment cylinder and the fin
Multiple bar-shaped troughs that channel is connected, the extending direction of all bar-shaped troughs are identical as the length direction of the fin channels；
Stainless steel steel wire is equipped in each bar-shaped trough, all stainless steel steel wires surround fin riding space.
There is the lubricity of bigger, fin can more be smoothly through by the fin riding space that stainless steel steel wire surrounds
Fin channels, rather than be stuck in fin channels.
Preferably, the cross section of the bar-shaped trough is in circle jaggy.
Preferably, the bottom of the engine base is further fixed on overturning-preventing seat.Cylinder can inevitably make in continuous swing process
Engine base shakes, and setting overturning-preventing seat can prevent engine base from toppling over.
Compared with prior art, the beneficial effects of the utility model are：
The utility model drives the rotation of orientation adjustment cylinder using driving mechanism, so that the angle of fin channels becomes
Change, this is allowed for can be towards different directions under the action of after leaving fin channels in inertia force by the fin of fin channels
It puts, by controlling the angle change size of fin channels, may be implemented to put fin " a positive and a negative ", to make
Subsequently can fin be placed into a manner of " a positive and a negative " in the gap between the adjacent flat tube of micro-channel heat exchanger, it is brazed
Afterwards, the fin stress " a positive and a negative " being soldered on micro-channel heat exchanger can cancel out each other, and avoid diagonal line bad, improve
Product qualification rate.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the positive and negative tooling of fin of the utility model.
Specific implementation mode
The technical solution of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment 1
As shown in Figure 1, a kind of positive and negative tooling of fin of the present embodiment, including engine base 1, the bottom of engine base 1 are provided with overturning-preventing
Seat 2.
Being rotatably assorted on engine base 1 has orientation adjustment cylinder 3, and it is logical that the center of orientation adjustment cylinder 3 offers the fin through engine base 1
Road 31；Around fin channels 31, the multiple bar-shaped troughs being connected with fin channels 31 are further opened on orientation adjustment cylinder 3
32, the extending direction of all bar-shaped troughs 32 is consistent with the length direction of fin channels 31, and the cross section of bar-shaped trough 32 is in band
Circle jaggy；Also, stainless steel steel wire is equipped in each bar-shaped trough 32, all stainless steel steel wires surround fin and slide
Space.There is the lubricity of bigger by the fin riding space that stainless steel steel wire surrounds so that fin more can successfully lead to
Fin channels 31 are crossed, without being stuck in fin channels 31.
The top of engine base 1 is hinged with cylinder 4, and middle part and the engine base 1 of the cylinder 4 are hinged, and top is then connected with air inlet
Pipe, the piston rod 41 in 4 bottom end of cylinder can freely stretch.In the present embodiment, the end of piston rod 41 is fixed with extending sleeve
42, the periphery of orientation adjustment cylinder 3 carries handle 33, which is hinged with handle 33.
A kind of course of work of the positive and negative tooling of fin of the present embodiment is：
Before starting the work, piston rod 41 be in origin (at this time handle 33 with, extending sleeve 42, piston rod 41 be in one
On straight line)；After start-up operation, air inlet pipe is inflated to cylinder 4, and 41 compression downlink of piston rod drives handle 33 relative to origin
It is rotated by 90 °, piston rod 41 goes downwards to maximum distance, is in the first working position at this time, and fin is put with " just " position；Then into
Tracheae stops inflation, and 4 pressure of cylinder disappears, and 41 uplink of piston rod drives handle 33 to return to origin, under the action of inertia force,
Handle 33 will not rest on origin after reaching origin but can rotate a certain angle in the opposite direction；Air inlet pipe is again at this time
Secondary inflation, piston rod 41 are pressurized downlink again, then handle 33 can continue to rotate in the opposite direction under the promotion of piston rod 41 until
180 degree is rotated relative to the first working position, piston rod 41 goes again downwards to maximum distance, is in the second working position, fin at this time
It is put with negation position；In air inlet pipe intermittently gas replenishment process, piston rod 41 constantly shrinks and extends, successively first
It is converted between working position and the second working position so that fin is put neatly in a manner of " a positive and a negative ".
