working principle:

First, the first clamping device 3 and the second clamping device 4 are in an open state. Put a pipe piece 100 into the first clamping device 3 and the second clamping device 4 . Then, loosen the adjustment bolt 93, push the adjustment block 91 forward, so that the pipe fitting 100 is pushed forward by the adjustment block 91, and lock the adjustment bolt 93 when the adjustment block 91 reaches the desired position, thereby adjusting the pipe fitting 100 exposed on the first position. The length of the outside of a clamping device 3, so that the length of the first bending section 200 can be controlled, and this benefit also includes that when the second pipe 100 is processed, the end of the pipe 100 will be clamped when the pipe 100 is clamped. The upper part directly bears on the adjustment block 91, which can ensure that the length of the first bending section 200 finally obtained by each processed pipe member 100 is equal.

When the length of the first bending section 200 is adjusted, the left support plate 21 is moved relative to the right support plate 22 by loosening the adjusting bolt 83. During the movement of the left support plate 21, the second clamping device 4 on it will And the second bending device 6 also moves accordingly, thereby adjusting the length of the other end of the pipe fitting 100 exposed outside the second clamping device 4, so that the length of the second bending section 300 can be controlled, and such benefits also include when When processing the second pipe 100 , since one end of the pipe 100 is positioned by the adjustment block 91 , the length of the second bent section 300 finally obtained at the other end of each pipe 100 is equal.

After the pipe fitting 100 is positioned by the adjustment block 91, the first cylinder 35 pushes the first movable die 32, so the first movable arc-shaped groove 34 on the first movable die 32 and the first fixed arc-shaped groove on the first fixed die 31 The groove 33 grips the pipe 100 . At the same time, the second cylinder 45 pushes the second movable mold 42, therefore, the second movable arc-shaped groove 44 on the second movable mold 42 and the second fixed arc-shaped groove 43 on the second fixed mold 41 separate the pipe fitting 100 Clamp on one side. Then the first drive cylinder 551 pushes the first rack 552 to move, and the first rack 552 pushes the first gear 553 to rotate. A first bending wheel 54 on the linkage rod 53 cooperates with the first arc portion 51 to bend the pipe 100 to form the first bending section 200 . Then the first cylinder 35 and the second cylinder 45 are cut off, but the first moving arc groove 34 is still closed with the first fixed arc groove 33, and the second moving arc groove 44 is still closed with the second fixed arc groove 43, only There is no clamping force on the pipe 100 . Then adjust the cylinder 72 to push the toggle plate 71 to rise, and the toggle plate 71 pushes the first bending section 200 during the rising process. Therefore, the first bending section 200 is twisted upward relative to the clamping position of the first clamping device 3 , The angle of the first bending section 200 is adjusted, and the torsion angle of the first bending section 200 can be adjusted by adjusting the stroke of the cylinder 72 through the screw 76 . The reason why the first air cylinder 35 and the second air cylinder 45 are cut off before the twisting angle is that the first bending section 200 can be twisted with less force, so that not only the size is accurate but also the pipe will not be twisted. If the first air cylinder 35 and the second air cylinder 45 are not continuously aired, the first air cylinder 35 and the second air cylinder 45 will be clamped very tightly, and adjusting the air cylinder 72 requires a lot of force to make the first bending section 200 twist, and the pipe fitting 100 The torsion part is prone to damage and rebound at the same time, so the precise requirement of the torsion angle cannot be guaranteed.

Then the first air cylinder 35 and the second air cylinder 45 are ventilated again, and the pipe 100 is clamped again. Then the second drive cylinder 651 promotes the second rack 652 to move, and the second rack 652 promotes the second gear 653 to rotate, and the second gear 653 drives the second moving rod 63 to move along the arc in the second arc hole 62. The second bending wheel 64 on the second linkage rod 63 cooperates with the second arc portion 61 to bend the pipe 100 to form the second bending section 300 . After the bending at both ends is completed, the first cylinder 35 and the second cylinder 45 ventilate and retreat, and the pipe fittings are taken out manually.

Therefore, the second bending section 300 is located in the horizontal plane, and the clamping position of the first bending section 200 relative to the first clamping device 3 is twisted, therefore, the first bending section 200 and the second bending section 300 Not in the same plane, but in different planes (as shown in Figure 7). The entire processing process is completed on one machine, only one clamping is required, the production efficiency is greatly improved, and the quality is stable.
