The principle of the expanding device of heat-conducting copper pipe nozzle is as follows in fan coil provided by the invention:
In use, the cylinder cap 33 on the cylinder 32 is loosened, so that the cylinder cap 33 divides with the elastic clip 34
It opens, the elastic slice of the elastic clip 34 and the inner wall of the recess separate, and the fixture block on the elastic clip 34 is located remotely from each other, so that
The diameter for the circular hole that the fixture block surrounds increases, and the fixed handle 53 of the flaring pin 5 is plugged in circular hole, the cylinder is tightened
Cap 33, so that the cylinder cap 33 squeezes the elastic clip 34, so that the inner wall of the recess squeezes the bullet of the elastic clip 34
Piece clamps the fixed handle 53 so that fixture block on the elastic clip 34 is close to each other.
In use, the distance between two described flaring pins 5 are adjusted according to the distance at U-shaped heat-conducting copper pipe both ends, by turning
First runner 23 is moved, second screw rod 22 is driven to rotate, second screw rod 22 is transmitted the force to described by screw thread
Second sliding block 24, so that second sliding block 24 is slided along the second sliding slot 21, so that the sliding panel 25 is close or remote
From the fixed plate 28, so as to adjust what is rotated on the flaring pin 5 and the fixed plate 28 rotated on the sliding panel 25
The distance between described flaring pin 5, simultaneously because distance changes between the sliding panel 25 and the fixed plate 28, for connecting
The tightness of first belt 41 of two belt pulleys 31 changes accordingly, by unclamping the fastening spiral shell
Bolt, adjusts the height of the sliding bar 26, so that being rotatablely connected the adjusting belt pulley 27 on the sliding bar 26 remains described
First belt 41 is in lucky tight state, adjusts the fastening bolt after the distance between two described flaring pins 5
It tightens and fixes the position of the sliding bar 26.
In use, the distance between two described circular holes are adjusted according to the distance at U-shaped heat-conducting copper pipe both ends, by rotating institute
Stating the second runner 66 drives the third screw rod 64 to rotate, and the third screw rod 64 transmits the force to the third by screw thread and slides
Block 65, the third sliding block 65 drive the placement block 67 mobile so as to adjust the distance between two circular holes and described the
The distance between one semi-circular recesses 671 and the second semi-circular recesses 611 will while adjusting the distance between two circular holes
The lid of cover board 68 closes, so that first protrusion is plugged in first shrinkage pool, the fastening screw 62 is unclamped, so that institute
Stating movable plate 69 can be free to slide, mobile by movable plate 69 described in the mobile band logical for placing block 67, by the activity
The position of plate 69 is set simultaneously, is fastened the fastening screw 62 and is fixed 69 position of movable plate, the cover board 68 is lifted
It rises, U-shaped heat-conducting copper pipe is placed on first semi-circular recesses 671 and the second semi-circular recesses 611 and U-shaped is led
The arch section of hot copper pipe contradicts the baffle 613, and the cover board 68 is covered and is closed, so that U-shaped heat-conducting copper pipe be fixed.Rotation
The crank 13, so that first screw rod 12 rotates, first screw rod passes to first sliding block by screw thread reduction
14, first sliding block 14 drives the fixing seat 2 mobile to the mounting table 61, and the flaring pin 5 contradicts U-shaped heat-conducting copper pipe
Both ends, the driving motor 4 being arranged in the fixing seat 2 rotates and drives two by the second belt 42 and the first belt 41
The folder cylinder 3 rotates, and the folder cylinder 3 drives the flaring pin 5 to rotate, and the flaring pin 5 is rotated into U-shaped heat-conducting copper pipe two
The diameter at end, the flaring pin 5 is greater than U-shaped heat-conducting copper pipe internal diameter, to be flared to the both ends of U-shaped heat-conducting copper pipe.
The expanding device of heat-conducting copper pipe nozzle is driven simultaneously by the driving motor 4 in fan coil provided by the invention
Two folder cylinders 3 rotate, and the folder cylinder 3 drives the flaring pin 5 to rotate, described when being driven by the rotation crank 13
The rotation of first screw rod, when first screw rod drives the fixing seat 2 mobile to the fixture 6, two flaring pins 5 are simultaneously
The both ends of U-shaped copper pipe are inserted into, the nozzle of U-shaped copper pipe is flared, the expansion that two flaring pins 5 are centainly expanded apart from holding
Mouthful distance be exactly it is certain, guarantee U-shaped copper pipe can be good at on aluminum fin-stock distance determine heat-conducting copper pipe end connect
It connects.By rotating first runner 23, drive second screw rod 22 is rotated, and is further driven to the movement of sliding panel 25,
The distance between two described flaring pins 5 can be adjusted, facilitates and adapts to different U shape copper pipes.Likewise, by described in rotation
Second runner 66 drives the third screw rod 64 to rotate, and further drives the placement block 67 is mobile to adjust first semicircle
The distance between connected in star 671 and second semi-circular recesses 611 facilitate and place different U-tube roads.The mounting table
Hinged cover board 68 can will be placed on the U-shaped copper on the first semi-circular recesses 671 and second semi-circular recesses 611 on 61
Pipe pressing.When flaring operation, the driving motor 4 is kept to rotate, U-shaped copper pipe is placed on the fixture 6, rotates the crank
The 13 control fixed stations 2 are mobile, so that the flaring pin 5 is inserted into the both ends of U-shaped copper pipe, it is easy to operate, and efficiently.
In addition, the setting of the folder cylinder 3 is convenient for changing the flaring pin 5, the spacing collar 52 on the flaring pin 5
Be arranged on the one hand limit it is described flaring pin 5 be inserted into it is described folder cylinder 3 depth, avoid flaring when, 5 stress of the flaring pin it is excessive into
Enter into the folder cylinder 3, on the other hand the spacing collar 52 limits the depth that the flaring pin 5 is inserted into U-shaped copper pipe, so that institute
