The vertical plate 2 is mounted on the top surface of the base plate 1, and is located on both sides of the base plate 1 along the length direction of the base plate 1. The top plate 3 is mounted on the top of the vertical plates 2 on both sides. The base plate 1, the top plate 3 and the vertical plates 2 on both sides together form a frame structure for supporting the relevant parts of the installation device. The support blocks 4 are rotatably mounted on the vertical plates 2 on both sides, and the support blocks 4 on both sides can rotate relative to the vertical plates 2 on both sides. The ball linear bearings 155 are mounted on the support blocks 4 on both sides, and are respectively used to support and install the slidable ball guide shafts 6. The ball guide shafts 6 are slidably mounted on the ball linear bearings 155 on both sides, and the ball guide shafts 6 on both sides can slide relative to the ball linear bearings 155 on both sides. The thumb cylinders 7 are mounted on adjacent ends of the ball guide shafts 6 on both sides, and are used to provide clamping force. The clamping arms 8 are mounted on the two moving ends of each thumb cylinder 7. The two clamping arms 8 mounted on the two moving ends of the same thumb cylinder 7 are symmetrically distributed. Driven by the thumb cylinders 7 on both sides, the two clamping arms 8 mounted on the two moving ends of the same thumb cylinder 7 move toward or in opposite directions. The clamping blocks 9 are rotatably mounted on the opposite surfaces of the two clamping arms 8 symmetrically distributed on the same side. The opposite surfaces of the two clamping blocks 9 symmetrically distributed on the same side are provided with grooves matching the pressure pipe. The two clamping blocks 9 symmetrically distributed on the same side are used to clamp one end of the pressure pipe. The bending part is mounted between the bottom plate 1 and the top plate 3, and is configured to bend the clamped pressure pipe.

[0037] The embodiment of the present disclosure provides a pressure pipe bending device, which controls the operation of the thumb cylinders 7 on both sides to change the distance between the two clamping arms 8 symmetrically distributed on the same side. In addition, the clamps of the two clamping blocks 9 symmetrically distributed on the same side are changed, so that the two ends of the pressure pipe are clamped and fixed respectively. Since the two clamping blocks 9 symmetrically distributed on the same side can rotate relative to the two clamping arms 8 symmetrically distributed on the same side, the ball guide shaft 6 on the same side can slide relative to the ball linear bearing 155, and the support block 4 on the same side can rotate relative to the vertical plate 2, during the process of the bending part bending the pressure pipe, the clamping blocks 9, ball guide shaft 6 and support block 4 on both sides can rotate, slide and rotate respectively, that is, move with the bending of the pressure pipe, so that the two ends of the pressure pipe can always be clamped and fixed. Compared with the method of counteracting the two ends of the pressure pipe, the stability of the pressure pipe during bending is further improved.

[0038] Optionally, combined Figure 1 and Figure 4As shown, the bending part includes a support wheel 10, a hydraulic cylinder 11, a lifting plate 12 and a bending wheel 13. The support wheel 10 is installed on the top surface of the base plate 1, and is located on both sides of the base plate 1 along the length direction of the base plate 1. The support wheels 10 on both sides are located between the top plates 3 on both sides, and the support wheels 10 on both sides are used to support the pressure pipe. The hydraulic cylinder 11 is installed on the top plate 3, and the moving end of the hydraulic cylinder 11 faces the base plate 1, and is used to provide driving force to realize the linear movement function. The lifting plate 12 is installed on the moving end of the hydraulic cylinder 11, and performs linear movement under the drive of the hydraulic cylinder 11. The bending wheel 13 is installed on the bottom surface of the lifting plate 12, and is used to press the pressure pipe. Among them, under the drive of the hydraulic cylinder 11, the bending wheel 13 can move between the support wheels 10 on both sides.

[0039] In the disclosed embodiment, the hydraulic cylinder 11 is controlled to operate, thereby driving the lifting plate 12 to move toward the base plate 1, thereby driving the support wheels 10 to move toward the base plate 1. The support wheels 10 continue to move toward the base plate 1, and the support wheels 10 continue to move toward the base plate 1, until the support wheels 10 contact the pressure pipes, which are clamped and fixed at both ends by the clamping blocks 9. The bending of the pressure pipes is completed.

[0040] Optionally, combined Figure 1 、 Figure 3 and Figure 4 As shown, the bending part further includes an optical axis 14.

[0041] In the disclosed embodiment, the bending member further includes an optical axis 14 that slidably passes through the top plate 3 and is connected to the lifting plate 12. The sliding direction of the optical axis 14 relative to the top plate 3 is the same as the direction of motion of the moving end of the hydraulic cylinder 11, thus serving as a guide and support. This improves the stability of the lifting plate 12 during movement and reduces the radial force exerted on the moving end of the hydraulic cylinder 11.

[0044] Optionally, combined Figure 2As shown, it also includes a bearing block 16 and a rotating shaft 17. The bearing blocks 16 are mounted on opposite sides of two symmetrically located clamping arms 8 on the same side. The rotating shaft 17 is mounted inside the two symmetrically located bearing blocks 16 on the same side.

The opposite ends of the two symmetrically distributed rotating shafts 17 are used to support and mount the two symmetrically distributed clamping blocks 9, thereby reducing friction between the two symmetrically distributed clamping blocks 9 and the two symmetrically distributed clamping arms 8, and improving the precision of the rotation of the two symmetrically distributed clamping blocks 9 relative to the two symmetrically distributed clamping arms 8.

[0046] Optionally, combined Figure 1 、 Figure 2 and Figure 4 As shown, it also includes a pin 18. The pin 18 is rotatably installed on the vertical plates 2 on both sides and is connected to the support blocks 4 on both sides.

[0047] In the embodiment of the present disclosure, the present invention further includes pins 18 rotatably passing through the vertical plates 2 on both sides and connected to the support blocks 4 on both sides. The pins 18 are used as connectors to achieve hinged connection, so that the support blocks 4 on both sides can rotate relative to the vertical plates 2 on both sides.

[0048] Optionally, combined Figure 1 、 Figure 2 and Figure 4 As shown, it also includes a support plate 19. The support plate 19 is respectively installed on the adjacent ends of the ball guide shafts 6 on both sides.

[0051] In the embodiment disclosed herein, a stop ring 20 is further included, which is mounted on the other end of each of the two ball guide shafts 6. The stop rings 20 on both sides are used to limit the position of the two ball guide shafts 6 to prevent them from falling off from the two ball linear bearings 155.

[0052] Optionally, combined Figure 1 and Figure 4 As shown, the base is also included. The base is respectively installed at the four corners of the bottom surface of the base plate 1.

[0053] In the embodiment of the present disclosure, the device further includes bases respectively installed at the four corners of the bottom surface of the base plate 1. The bases at the four corners are used to abut against the ground or the desktop to support the entire device.
