[0002] A pipe bender refers to a machine used for bending pipes, which is roughly divided into a numerical control pipe bender, a hydraulic pipe bender, etc. It is applied to pipeline laying and repair in aspects such as electric power construction, highway and railway construction, bridges, ships, etc., and can also perform pipe bending treatment on high-strength automotive pipes.

[0003] The existing pipe benders for high-strength automotive pipes have the following problems in actual use:

[0004] 1. When the traditional pipe bender for high-strength automotive pipes is actually used, when bending the high-strength pipe, the position where the high-strength pipe needs to be fixed is fixed on the pipe bender. At this time, a rotating grip is required to fix the high-strength pipe. The grip of the traditional pipe bender is relatively short, so it is quite laborious to rotate the grip, and it is rather troublesome to use.

[0005] 2. During the use of most pipe benders for high-strength automotive pipes, when bending the high-strength pipe, the position where the high-strength pipe needs to be fixed is fixed on the pipe bender. When fixing, the high-strength pipe needs to be squeezed and fixed. Since the inside of the high-strength pipe is empty, when squeezing and fixing the high-strength pipe, the high-strength pipe may be deformed by extrusion. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a pipe bender for high-strength automotive pipes to solve the technical problems raised in the background technique.

[0030] As Figures 1-6As shown in the figure, the pipe bender for high-strength automotive pipes of the present utility model includes a workbench 1. A control device 2 is installed inside the workbench 1. A first shaft 3 is provided at the top of the workbench 1. A fixing plate 4 is welded to the surface of the first shaft 3. A side plate 5 is welded to the side of the fixing plate 4. A turning handle 8 is provided on the side of the side plate 5. Flap pieces 9 are welded to both ends of the turning handle 8. A grip 10 is installed on the surface of the turning handle 8. A cavity is opened inside the grip 10. The flap pieces 9 are located inside the cavity. An anti-slip pad 11 is adhered to the surface of the grip 10. By installing the anti-slip pad 11, the friction between the grip 10 and the palm can be enhanced by the protective pad, so that the hand will not slip during rotation and it is more stable during use. A sphere is adhered to the surface of the anti-slip pad 11. The grips 10 are distributed symmetrically. By installing the grips 10, when the turning handle 8 needs to be rotated, the grip 10 can be first pulled outwards. When it moves to a suitable position, the flap piece 9 will be stuck inside the cavity to limit the grip 10 on the turning handle 8. At this time, the distance to the center point is extended through the grip 10, and it is more labor-saving to rotate at this time and it is very convenient to use.

[0031] A fixing frame 12 is welded to the top of the fixing plate 4. A first chute 13 is opened at the top of the fixing frame 12. A support rod 16 is provided at the bottom of the fixing frame 12. A fixing rod 14 is welded to the surface of the support rod 16. The fixing rod 14 is located inside the first chute 13. The other end of the fixing rod 14 is welded to a baffle 15. The bottom of the baffle 15 is in contact with the top of the fixing frame 12. A sphere is welded to the top of the baffle 15. By installing the support rod 16 and inserting the support rod 16 into the high-strength pipe, at this time, the support rod 16 provides a support effect inside the high-strength pipe, so that the high-strength pipe will not be deformed by extrusion and it is very convenient to use.

[0032] A bearing 18 is welded to the surface of the first shaft 3. A first pressing wheel 17 is welded to the surface of the bearing 18. One end of the first shaft 3 penetrates through the fixing plate 4. A fixing seat 19 is welded to the surface of the first shaft 3. The bottom of the fixing seat 19 is welded to the fixing plate 4. By installing the bearing 18, after the first pressing wheel 17 is installed on the first shaft 3, it has a rotatable effect and it is very convenient to use.

[0033] A second chute 28 is opened at the top of the fixing plate 4. A second shaft 22 is provided inside the second chute 28. A second pressing wheel 21 is installed on the surface of the second shaft 22. Both ends of the second shaft 22 penetrate through a clamping plate frame 23. Retaining rings 20 are welded to both ends of the second shaft 22. The bottom of the retaining rings 20 is in contact with the fixing plate 4. By opening the second chute 28, at this time, the second shaft 22 is located inside the second chute 28. The second chute 28 provides the second pressing wheel 21 with the ability to move on the basis of the second chute 28 and it is very convenient to use.

[0034] A turntable 25 is provided on the side of the clamping plate frame 23. A lead screw 7 is welded to the side of the turntable 25. An internally threaded seat 6 is installed on the surface of the lead screw 7. One end of the internally threaded seat 6 is welded to a side plate 5. The other end of the lead screw 7 is welded to a turning handle 8. By installing the turntable 25, when the lead screw 7 is rotated to move the clamping plate frame 23, the turntable 25 can prevent the clamping plate frame 23 from rotating together with the lead screw 7, enabling the clamping plate frame 23 to move stably and having strong stability during use.

[0035] A first clamping plate 24 is welded to the top of the workbench 1. An extrusion device 26 is installed on the top of the workbench 1. One end of the extrusion device 26 is welded to a second clamping plate 27. By installing the extrusion device 26, the second clamping plate 27 is moved by the extrusion device 26. At this time, the high-strength automotive pipe can be placed between the first clamping plate 24 and the second clamping plate 27, providing a fixing effect for the high-strength automotive pipe and having strong stability during use.

[0036] The working principle of the bending machine for high-strength automotive pipes: When using the bending machine for high-strength automotive pipes, one end of the high-strength automotive pipe should first be placed between the first extrusion wheel 17 and the second extrusion wheel 21. Subsequently, the extrusion device 26 is controlled by the control device 2 to move the second clamping plate 27. At this time, the high-strength automotive pipe is located between the first clamping plate 24 and the second clamping plate 27. The first clamping plate 24 and the second clamping plate 27 can provide a left-right limiting effect for the high-strength automotive pipe. When extruding and fixing the high-strength automotive pipe, the sphere can be held to move the fixing rod 14 to drive the support rod 16, and the support rod 16 is inserted into the high-strength pipe. At this time, the support rod 16 provides a supporting effect inside the high-strength pipe, preventing the high-strength pipe from being deformed by extrusion. Subsequently, the grip 10 is first pulled outwards. When it moves to a suitable position, the stop piece 9 will be stuck inside the cavity to limit the grip 10 on the turning handle 8. At this time, the distance from the grip 10 to the origin is extended, making it more labor-saving to rotate and very convenient to use. Then, the lead screw 7 is driven to rotate. At this time, based on the internally threaded seat 6, the lead screw 7 moves the clamping plate frame 23, driving the second extrusion wheel 21 to move on the second chute 28, enabling the first extrusion wheel 17 and the second extrusion wheel 21 to extrude and fix the high-strength automotive pipe. Subsequently, the control device 2 is used to drive the first shaft 3 to drive the fixing plate 4 to rotate, thereby realizing the bending process of the high-strength automotive pipe.
