Description

Technical Field

[0001] This application relates to the field of metal pipe processing technology, specifically to a pipe bending device. Background Technology

[0002] When assembling large testing equipment, it is usually necessary to install various bent metal fittings. These fittings are generally used to pressurize pressure gauges and protect the cables of instruments. When customizing these metal fittings, it is usually necessary to bend them at multiple points to smoothly realize the relevant functions within the testing equipment.

[0003] Existing pipe bending devices can generally only bend one point of a metal pipe at a time. When the same pipe needs to be bent twice, it needs to be removed and repositioned before the second bending process, resulting in low efficiency. Utility Model Content

[0004] To address the aforementioned deficiencies in the prior art, this application provides a tube bending device that improves the efficiency of tube bending and has strong practicality.

[0005] To achieve the above objectives, the present invention employs the following technology: A tube bending device, comprising: The pipe bending mechanism has two sets. Each set includes a mounting platform, a pressing block, a fixing block, and a lifting block. The mounting platforms are all set on a support plate. One mounting platform is fixed to the upper surface of the support plate, and the other mounting platform is movable along the length of the support plate. The pressing blocks are all set on the mounting platforms. The fixing blocks are all set directly above the pressing blocks. The fixing blocks are all movable along the height of the support plate. The lower surface of each fixing block is provided with a first arc surface. The central axis of the first arc surface is parallel to the width of the support plate. The lifting blocks are respectively set on the opposite sides of the two pressing blocks. The lifting blocks are all movable along the height. The upper surface of each lifting block is provided with a second arc surface. The central axis of the second arc surface is parallel to the width. A limiting mechanism is provided between two mounting platforms. The limiting mechanism includes two limiting plates that are spaced parallel to each other along the width direction. One limiting plate is fixed and the other limiting plate is movable along the width direction.

[0006] Furthermore, a first electric lead screw is provided on the bearing plate, the driving direction of the first electric lead screw is parallel to the length direction, a first mating block is threaded onto the first electric lead screw, and the other mounting platform is provided on the upper surface of the first mating block.

[0007] Furthermore, each mounting platform is provided with a pair of first mounting brackets and a pair of sliding rods. A second electric lead screw is mounted on each of the first mounting brackets. The driving direction of the second electric lead screw and the sliding rod are both parallel to the height direction. The drive shaft of the second electric lead screw is threaded with a second mating block. The two second mating blocks are respectively connected to the fixed block and the lifting block. A slider is slidably sleeved on each of the sliding rods. The two sliders are respectively connected to the fixed block and the lifting block.

[0008] Furthermore, a support rod is installed on the support plate, and a second mounting bracket is installed on the support rod. One of the limiting plates is fixed to one end of the second mounting bracket. A third electric lead screw is installed on the second mounting bracket. The driving direction of the third electric lead screw is parallel to the width direction. The drive shaft of the third electric lead screw is threadedly engaged with a third mating block.

However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figure 1As shown, this embodiment provides a tube bending device, including a tube bending mechanism 1 and a limiting mechanism 3.

[0016] Specifically, such as Figure 1 As shown, there are two sets of pipe bending mechanisms 1. Each set of pipe bending mechanisms 1 includes a mounting platform 11, a pressing block 12, a fixing block 13, and a lifting block 14. The mounting platforms 11 are all mounted on a support plate 2. One mounting platform 11 is fixed to the upper surface of the support plate 2, and the other mounting platform 11 is movable along the length direction of the support plate 2. As a preferred embodiment, as shown... Figure 1 As shown, a first electric lead screw 21 is provided on the bearing plate 2. The driving direction of the first electric lead screw 21 is parallel to the length direction. A first mating block 22 is threaded onto the first electric lead screw 21. The other mounting platform 11 is provided on the upper surface of the first mating block 22. The first electric lead screw 21 is used to drive the other mounting platform 11 to move.

[0017] like Figure 1 and Figure 2 As shown, the pressing blocks 12 are all disposed on the mounting platform 11, and the fixing blocks 13 are all disposed directly above the pressing blocks 12. The fixing blocks 13 are all movable along the height direction of the bearing plate 2. The lower surface of each fixing block 13 is provided with a first arc surface 15, the central axis of which is parallel to the width direction of the bearing plate 2. The lifting blocks 14 are respectively disposed on the opposite sides of the two pressing blocks 12. The lifting blocks 14 are all movable along the height direction. The upper surface of each lifting block 14 is provided with a second arc surface 16, the central axis of which is parallel to the width direction. As a preferred embodiment, as shown... Figure 2 As shown, each mounting platform 11 is provided with a pair of first mounting brackets 17 and a pair of slide rods 18. A second electric lead screw 19 is mounted on each of the first mounting brackets 17. The driving direction of the second electric lead screw 19 and the slide rod 18 are both parallel to the height direction. The drive shaft of the second electric lead screw 19 is threaded with a second mating block 110. The two second mating blocks 110 are respectively connected to the fixed block 13 and the lifting block 14. A slider 111 is slidably sleeved on each of the slide rods 18. The two sliders 111 are respectively connected to the fixed block 13 and the lifting block 14. The pair of second electric lead screws 19 are used to drive the fixed block 13 and the lifting block 14 to move respectively.

[0018] Specifically, such as Figure 1 and Figure 3 As shown, the limiting mechanism 3 is disposed between two mounting platforms 11. The limiting mechanism 3 includes two limiting plates 31 arranged parallel to each other along the width direction. One limiting plate 31 is fixedly disposed, and the other limiting plate 31 is movable along the width direction. As a preferred embodiment, as shown... Figure 1As shown, a support rod 32 is installed on the support plate 2, and a second mounting bracket 33 is installed on the support rod 32. One of the limiting plates 31 is fixed to one end of the second mounting bracket 33. A third electric lead screw 34 is installed on the second mounting bracket 33. The driving direction of the third electric lead screw 34 is parallel to the width direction. The drive shaft of the third electric lead screw 34 is threadedly engaged with a third mating block 35. The other limiting plate 31 is fixed to the third mating block 35.

[0019] During operation, the pipe to be bent is inserted between the pressing block 12 and the fixing block 13 of each bending mechanism 1, and between the two limiting plates 31 of the limiting mechanism 3, so that the pipe to be bent rests on the pressing block 12 of each bending mechanism 1, and the lifting blocks 14 are all located below the pipe to be bent; the position of the pipe to be bent and the movable mounting platform 11 is adjusted so that the two bending points of the pipe to be bent are respectively located at the contact points between the pipe to be bent and the two pressing blocks 12; at this time, the fixing block 13 is moved downward and the distance between the limiting plates 31 is reduced, so that the pressing block 12 and the fixing block 13 clamp the pipe to be bent, and the limiting plates 31 can make the pipe to be bent perpendicular to the first arc surface 15 and The central axis of the second arc surface 16 is then moved upwards. The two lifting tubes 14 are moved upwards to make contact with the pipe to be bent and push it upwards, so that the pipe to be bent is bent at the first arc surface 15. With this design, when the same pipe is bent twice, it is not necessary to remove it and reposition it. The bending work at two points can be performed at the same time, which improves the bending efficiency. For pipes to be bent where the bending directions at the two points are not in the same plane or are opposite, after the first bending work is completed, there is no need to remove the pipe. After rotating the pipe, the pipe can be fixed again to continue the second bending. The operation is convenient and the bending efficiency is further improved.

[0020] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
