Firstly, an operator places the device on a mounting plate, then screws are placed in a first threaded hole 4 and a second threaded hole 5, the screws are twisted to move backwards to drill into the mounting plate to fix the device, then the clamping device 12 is pulled to be separated from the clamping hole 11 to loosen the clamping sleeve 9, the clamping sleeve 9 can be pulled to move upwards, the clamping sleeve 9 moves upwards to drive the convex sliding rod 7 to move upwards through the connecting rod 8, when the convex sliding rod 7 moves upwards to a proper position, the clamping device 12 is loosened to reset, the clamping device 12 is clamped into the clamping hole 11 to fix the clamping sleeve 9, then the convex sliding rod 7 is fixed, so that the convex sliding rod 7 moves upwards to increase the pulling stroke, the operator can pull the fan-shaped pinch roller 3 to bend the thin iron pipe more laborsavingly to pull the convex sliding rod 7 to rotate forwards, the convex sliding rod 7 rotates forwards to drive the convex grooved rod 6, the convex grooved bar 6 rotates forwards to drive the fan-shaped pinch roller 3 to rotate forwards, the convex sliding bar 7 stops being pulled after the fan-shaped pinch roller 3 rotates forwards by 180 degrees, the convex grooved bar 6 faces downwards, the thin iron pipe can be placed into the second left-side clamping groove 1401, the lower end of the thin iron pipe is fixed by hands, the convex sliding bar 7 can be pulled to rotate forwards by 180 degrees again after the thin iron pipe is placed, the first clamping groove 301 is contacted with the thin iron pipe due to the fan-shaped pinch roller 3 rotating forwards by 180 degrees, the thin iron pipe is bent by the fan-shaped pinch roller 3 through the first clamping groove 301, the thin iron pipe on the left side can be taken out after the thin iron pipe on the left side is bent, the other thin iron pipe is placed into the second right-side clamping groove 1401, the convex sliding bar 7 is pulled to rotate forwards again according to the operation, the fan-shaped pinch roller 3 bends the thin iron pipe again, the thin iron pipe can be bent repeatedly, the fastening bolt 16 is rotated backwards and moves outwards when the thin iron pipe is required, the fastening bolt 16 moves outwards to be separated from the outer third threaded hole 15, so that the second moving sleeve 14 can be pulled to move inwards, the second moving sleeve 14 moves inwards to drive the fastening bolt 16 to move inwards, when the fastening bolt 16 moves inwards to the front side of the inner third threaded hole 15, the second moving sleeve 14 stops being pulled, the fastening bolt 16 can be twisted to move forwards, the fastening bolt 16 moves inwards to be matched with the inner third threaded hole 15 to fix the second moving sleeve 14, and the fastening bolt 16 stops being twisted, so that the thin iron pipe can be placed into the second clamping groove 1401 to be bent. After thin iron pipe is whole to be bent, can stop to stimulate convex slide bar 7, pull chucking device 12 outwards to remove and block the hole 11 and break away from again, promote cutting ferrule 9 and remove downwards and reset, and then drive convex slide bar 7 and remove downwards and reset, loosen chucking device 12 card and block and fix cutting ferrule 9 in the hole 11, twist the screw outwards to remove and break away from in the mounting panel again, and break away from with this device with first screw hole 4 and second screw hole 5, can remove this device to next position, because this device is less, operating personnel's the carrying has been made things convenient for.
After this device is fixed, operating personnel can stimulate arm-tie 123 and move forward, arm-tie 123 moves forward and drives and remove card pole 122 and move forward, first compression spring 124 compresses, it breaks away from with calorie hole 11 to remove card pole 122 forward movement, promote cutting ferrule 9 rebound, cutting ferrule 9 rebound drives convex slide bar 7 rebound through connecting rod 8, convex slide bar 7 rebound to suitable position, stop to stimulate cutting ferrule 9, loosen arm-tie 123, because of the effect of first compression spring 124, it is fixed with cutting ferrule 9 to move card pole 122 rebound and insert card hole 11 in, and then it is fixed with convex slide bar 7, can begin to bend the thin iron pipe. After the thin iron pipe is completely bent, the movable clamping rod 122 can be separated from the clamping hole 11 again according to the operation, the clamping sleeve 9 is pulled to move downwards to drive the convex sliding rod 7 to move downwards through the connecting rod 8 to reset, the pulling plate 123 is loosened, and the movable clamping rod 122 moves backwards to be inserted into the clamping hole 11 to fix the clamping sleeve 9.
When the fan-shaped pressing wheel 3 rotates forwards 180 degrees, the fan-shaped pressing wheel 3 enables the thin iron pipe to be contacted with the arc-shaped clamping strip 21, and then the thin iron pipe makes the arc-shaped clamping strip 21 move outwards, the arc-shaped clamping strip 21 moves outwards to drive the arc-shaped sealing ring 22 to move outwards, the third compression spring 23 compresses, the arc-shaped sealing ring 22 moves outwards to push the piston 20 to move inwards through the hydraulic oil 24, the second compression spring 19 compresses, and then the arc-shaped clamping strips 21 at the front side and the rear side are used for auxiliary fixation of the thin iron pipe, when the fan-shaped pinch roller 3 bends the thin iron pipe, the thin iron pipe is not contacted with the arc-shaped clamping strip 21, and due to the action of the second compression spring 19, the piston 20 moves outwards, and pushes the arc-shaped sealing ring 22 to move inwards through the hydraulic oil 24, and due to the action of the third compression spring 23, the arc-shaped sealing ring 22 is better reset, and the arc-shaped sealing ring 22 moves inwards to reset and drives the arc-shaped clamping strip 21 to move inwards to reset. When the thin iron pipe is thin, the thin iron pipe slides from the arc-shaped clamping strip 21, and the arc-shaped clamping strip 21 limits the thin iron pipe. Therefore, the bending effect can be prevented from being influenced by the random movement of the thin iron pipe.
When the thin iron pipe is placed in the second slot 1401, the thin iron pipe contacts the first magnet block 26 and the second magnet block 28, and the first magnet block 26 and the second magnet block 28 attract the thin iron pipe to fix the thin iron pipe, so that the thin iron pipe can be bent. When the thin iron pipe is bent, the operator takes the thin iron pipe out of the second clamping slot 1401, and the first magnet block 26 and the second magnet block 28 are separated from the thin iron pipe. Therefore, the thin iron pipe can be bent more stably.
When an operator pulls the convex sliding rod 7 to rotate forward so that the fan-shaped pressing wheel 3 rotates forward, the fan-shaped pressing wheel 3 also drives the first sliding block 30 and the second sliding block 31 to rotate forward, and the first sliding block 30, the second sliding block 31 and the annular sliding groove 29 play a role in guiding the fan-shaped pressing wheel 3. When the sector-shaped pinch roller 3 stops rotating forwards, the first slide block 30 and the second slide block 31 stop rotating forwards. Therefore, the fan-shaped pressing wheel 3 can rotate positively and stably without influencing the bending of the thin iron pipe.
It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
