The specific embodiment

Below in conjunction with accompanying drawing, a kind of preferred implementation of coiling shutdown of the utility model is made detailed description:

As shown in Figure 1, this is a kind of to coil the fixed pedestal 1 that shutdown comprises that fixing horizontal is provided with, and rotates on the fixed pedestal 1 and is provided with rotating basis 2, and rotating basis 2 can horizontally rotate on fixed pedestal 1.Be provided with motor below the fixed pedestal 1, in order to 2 rotations of driven in rotation pedestal.

Rotating basis 2 is provided with coil pipe driving wheel 3, fixedly lock dog 4 and movable lock dog 5.As shown in Figure 3, the concentric coil pipe driving wheel 3 that fixedly installs on the rotating shaft of rotating basis 2 offers the semicircular dish folding of circle rail groove 13 on the wheel face of coil pipe driving wheel 3, and dish folding rail groove 13 is for what tilt, and it is the same to be similar to screw thread.As shown in Figure 4, coil pipe driving wheel 3 is combined by driving wheel patrix 31 and driving wheel counterdie 32, and its interface is positioned at dish folding rail groove 13.Driving wheel counterdie 32 is fixedly installed on the rotating basis 2, and driving wheel patrix 31 is fixed on the thick axle, and this thick axle is through in the driving wheel counterdie 32, thereby makes driving wheel patrix 31 driving wheel counterdie 32 activity vertically relatively.The thick axle that connects driving wheel patrix 31 is connected with a hydraulic cylinder, in order to moving up and down of control driving wheel patrix 31.

As shown in Figure 3; The right of coil pipe driving wheel 3 fixedly installs a fixedly lock dog 4; Fixedly the lower surface of lock dog 4 is the plane, and is tangent with the lower end of coil pipe driving wheel 3, also offers dish folding rail groove 13 on it; Dish folding rail groove 13 be about towards the angled straight lines groove, and be spliced into the smooth dish folding rail groove 13 of a whole piece with dish folding rail groove 13 on the coil pipe driving wheel 3.

Fixedly the below of lock dog 4 fixedly installs locking cylinder 7; The push rod top of locking cylinder 7 fixedly installs movable lock dog 5; Movable lock dog 5 can move up and down and lock; The upper surface of movable lock dog 5 also be and fixing parallel plane, lock dog 4 lower surfaces that as shown in Figure 2, the dish that also offers the cross section semicircular in shape of inclination on it is rolled over rail groove 13; And be separated by with the dish folding rail groove 13 of fixing lock dog 4 and constitute a locking crack 12, fixedly lock dog 4 constitutes steel pipe jointly with movable lock dog 5 and locking cylinder 7 etc. and locks assembly.

Fixedly install jacking block oil cylinder 8 on the fixed pedestal 1; It is positioned at the below of coil pipe driving wheel 3, and the push rod top of jacking block oil cylinder 8 fixedly installs a jacking block slide rail 9, and sliding on the jacking block slide rail 9 is provided with a passive jacking block 6 of coil pipe; The passive jacking block 6 of coil pipe can move left and right; Also fixedly install a jacking block translation oil cylinder 10 on the jacking block slide rail 9, its push rod is connected with the passive jacking block 6 of coil pipe, thereby drives passive jacking block 6 move left and right of coil pipe.As shown in Figure 2, the upper surface of the passive jacking block 6 of coil pipe also is and fixing parallel plane, lock dog 4 lower surfaces, also offers the dish folding rail groove 13 of the cross section semicircular in shape of inclination on it, and is separated by with the dish folding rail groove 13 of coil pipe driving wheel 3 and constitutes a dish folding crack 11.Dish folding crack 11 is positioned on the straight line of an inclination with locking crack 12 jointly.

In the time of the work of this coiler, open locking cylinder 7 and jacking block oil cylinder 8 earlier, its control activity lock dog 5 is moved down with the passive jacking block 6 of coil pipe; Dish folding crack 11 and locking crack 12 are opened, steel pipe is put into dish folding crack 11 and locking crack 12, control driving wheel patrix 31 and move up this moment; The dish folding rail groove 13 of coil pipe driving wheel 3 is opened, and control activity lock dog 5 moves up with the passive jacking block 6 of coil pipe then, and steel pipe is clamped in the dish folding rail groove 13; Control driving wheel patrix 31 moves down; Steel pipe thoroughly is clamped in the dish folding rail groove 13, and steel pipe is extruded an angle of inclination, be beneficial to later dish folding; Starting motor-driven rotating basis 2 is rotated counterclockwise; Open the passive jacking block 6 of jacking block translation oil cylinder 10 driving coil pipes simultaneously and move to right, the rotary speed of the dish folding rail groove 13 on its move to right speed and coil pipe driving wheel 3 equates that the stiff end of locking assembly traction steel pipe is rotated counterclockwise; The movable end of steel pipe is coiled folding rail groove 13 and is limited to all the time on the angled straight lines; To the right under the draw, steel pipe is bent out the curved of screw-type accurately, and the steel pipe after the bending is taken off at the rotation bending effect of coil pipe driving wheel 3 and the passive jacking block 6 of coil pipe; Rotating basis 2 returns back to the home position; With reverse the putting into dish folding crack 11 and lock crack 12 of the steel pipe after the bending, repeat above bending process repeatedly, just can accurately the straight steel pipe dish be converted into the plate-like of round complications as shown in Figure 5.
