The working principle of the invention is as follows:
First, when it is necessary to clamp the straight pipe, the user places the straight pipe on the two placing seats 31. Subsequently, by controlling the electric telescopic rod 32, the placing seat 31 drives the straight pipe to move, so that the circle center of the straight pipe is aligned with the circle center of the mechanical clamping jaw 3. In this way the straight tube is moved exactly between the two sets of mechanical jaws 3. Next, by controlling the first hydraulic lever 10, the two sets of mechanical clamping jaws 3 are folded toward the relatively close side, so that the straight pipe is limited. Then, the user screws threaded rod 6, and under the spacing guide of deflector 9, clamp splice 7 can be moved to the one side that is close to the body, further carries out spacing centre gripping to the straight tube. Finally, the electric telescopic rod 32 drives the placing seat 31 to move downwards, so that the placing seat 31 moves in the connecting groove 33 and is far away from the straight pipe, and space is reserved for subsequent processing operation.
When the straight pipe needs to be subjected to thermoplastic bending, the clamping operation is repeated. After the straight pipe is clamped and fixed, the user penetrates the bent pipe spring 34 into the straight pipe. According to the radius of the bent pipe spring 34 and the pipe body, the user adjusts the position of the insert block 35, so that the second screw block 38 moves in the positioning groove 39 until the insert block 35 and the fixing plate 37 move to the position of the end part of the bent pipe spring 34. Then, the insert 35 is inserted into the end of the bent-tube spring 34, and the second screw 38 is screwed down to extend into the circular hole at the bottom of the positioning groove 39, thereby restraining the bent-tube spring 34. Next, by controlling the second hydraulic lever 22, the two semicircular blocks are folded, and the electric heater 21 is clamped outside the straight pipe and heated. According to the heating range required by the user, the second motor 28 is controlled to rotate the screw rod 26, and the movable seat 25 horizontally moves under the limit guide of the guide rod 27. Simultaneously, the third hydraulic rod 24 moves in the upper adjusting groove 29 and the lower adjusting groove 29 to drive the base 23 and the electric heating element 21 thereon to horizontally move, so that the position of the pipe body to be heated is accurately heated. After the heating is finished, the second motor 28 drives the movable seat 25 to reset, and the base 23 moves to the open slot 30. Then, the second hydraulic lever 22 operates again to spread out the two semicircular blocks. After the expansion, the third hydraulic rod 24 drives the base 23 and the electric heating element 21 to move downwards in the open groove 30, so that the heating operation is completed.
Subsequently, by controlling the first motor 18, the gear 17 is rotated. Because the gear 17 is meshed with the toothed rail 16, and the sliding block 12 moves on the sliding rail 14 under the limit guide of the sliding rail 14, the connecting column 11 moves in the moving groove 20, and therefore the upper clamping piece is driven to move. When the clamping member provided on the connecting post 11 moves to a position of a desired bending angle, the first motor 18 stops operating. Then, the bent-tube spring 34 is released from the limit and is pulled out. Then, the clamping block 7 is far away from the pipe body, the mechanical clamping jaw 3 is unfolded, and the user can take out the bent pipe body.
For clamping and fixing of the bent pipe, the operation process is similar. The clamping member is moved to the corresponding position by controlling the first motor 18 according to the bending angle of the bent pipe. Then, the bent pipe is placed in two clamping pieces, and the mechanical clamping jaw 3 limits the bent pipe by controlling the first hydraulic rod 10. Finally, the clamping block 7 is used for further limiting and clamping the bent pipe by screwing the threaded rod 6.
