Description

Technical Field

[0001] This utility model relates to the field of CNC bending machines, and in particular to a high-precision CNC bending machine. Background Technology

[0002] In industries such as construction, automobile manufacturing, and aerospace, steel pipes are widely used due to their high strength and good toughness, making bending a crucial process. Traditional bending equipment struggles to precisely control the bending angle and radius, easily causing steel pipe springback and deformation, resulting in a high scrap rate. The emergence of high-precision CNC bending machines provides an effective way to achieve high-precision and high-efficiency steel pipe bending, greatly improving production quality and efficiency.

[0003] Existing CNC bending machines often simply fix the steel pipe manually, which leads to unstable stress on the steel pipe during the bending process. This can easily result in bending angles that do not meet standards, low precision, and affect the later use of the steel pipe. Utility Model Content

[0004] In view of this, the present invention provides a high-precision CNC bending machine. The main technical problem to be solved is that existing CNC bending machines often simply fix the steel pipe manually, which leads to unstable stress on the steel pipe during the bending process, which can easily cause the bending angle to not meet the standard, resulting in low precision and affecting the later use of the steel pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision CNC bending machine, comprising a mounting block, wherein a first moving groove is provided inside the mounting block, a second moving groove is provided at the top of the first moving groove, and the number of the second moving grooves is two; a first lead screw is movably mounted on the inner wall of the mounting block, a moving plate is threadedly connected to the outer surface of the first lead screw, and a locking pin is fixedly connected to the upper surface of the moving plate, and the number of the locking pins is two; a clamping member is provided above the mounting block, and the number of the clamping members is two; an inclined groove is provided at the bottom of the clamping member, and the locking pin is located inside the inclined groove; a limiting block is fixedly connected to the side wall of the clamping member, and the number of the limiting blocks is multiple; the limiting blocks are slidably mounted on the side wall of the mounting block.

[0006] By adopting the above technical solution, the steel pipe to be processed can be fixed in place, which effectively avoids uneven stress on the steel pipe during bending and increases the precision of steel pipe bending.

[0007] As a further description of the above technical solution:

[0008] A torsion disc is fixedly connected to the side wall of the first lead screw, and a handle is fixedly connected to the side of the torsion disc away from the first lead screw.

[0009] By adopting the above technical solution, turning the handle can drive the torsion plate and the first lead screw to rotate.

[0010] As a further description of the above technical solution:

[0011] A sliding rod is fixedly connected to the inner wall of the mounting block, and a movable plate is sleeved on the outer surface of the sliding rod.

[0012] By adopting the above technical solution, the slide bar can restrict the movement of the moving plate and prevent the moving plate from deviating during the movement.

[0013] As a further description of the above technical solution:

[0014] A workbench is provided below the mounting block. A first groove is formed on the upper surface of the workbench. A second lead screw is movably installed on the inner wall of the first groove. A first throttle is fixedly connected to the side wall of the second lead screw. A mounting block is threadedly connected to the outer surface of the second lead screw. A connecting block is fixedly connected to the side wall of the workbench. A fixing post is fixedly connected to the upper surface of the connecting block.

[0015] By adopting the above technical solution, rotating the first throttle can drive the second lead screw to rotate, which in turn can drive the mounting block to move. The fixed column is used to cooperate with the bending column to bend the steel pipe.

[0016] As a further description of the above technical solution:

[0017] A mounting bracket is fixedly connected to the lower surface of the workbench, a motor is fixedly connected to the upper surface of the mounting bracket, a rotating block is fixedly connected to the output end of the motor, and the rotating block is movably mounted on the lower surface of the connecting block.

[0018] By adopting the above technical solution, the motor can drive the rotating block to rotate.

[0019] As a further description of the above technical solution:

[0020] The upper surface of the rotating block is provided with a second groove, the inner wall of the second groove is movably installed with a third lead screw, the side wall of the third lead screw is fixedly connected with a second throttle, the outer surface of the third lead screw is threaded with a moving block, the upper surface of the moving block is fixedly connected with a bending column, and the lower surface of the workbench is fixedly connected with four support legs.

[0021] By adopting the above technical solution, when it is necessary to adjust the position of the bending column, the second throttle is turned to drive the third lead screw to rotate, which in turn drives the moving block and the bending column to move, and the support leg can support the worktable.

[0022] By employing the above technical solution, the high-precision CNC bending machine of this utility model has at least the following beneficial effects:

[0023] Compared with existing technologies, this high-precision CNC bending machine uses a handle, a torsion plate, a first lead screw, a moving plate, a locking pin, a slant groove, and clamping components. Rotating the handle drives the torsion plate and the first lead screw to rotate, which in turn moves the moving plate. When clamping the steel pipe, the moving plate moves away from the torsion plate, causing the locking pin to move away from the torsion plate as well. Due to the slant groove, adjacent clamping components move closer together, effectively securing the steel pipe. When clamping is not needed, the moving plate moves closer to the torsion plate. In contrast, existing bending machines often rely on manual fixing of the steel pipe, which leads to unstable stress during bending, easily resulting in non-standard bending angles, low precision, and negatively impacting the pipe's future use. This high-precision CNC bending machine effectively secures the steel pipe, preventing uneven stress during bending and increasing the precision of the bending process.

[0024] Compared with existing technologies, this high-precision CNC bending machine uses a fixed column, a bending column, a third lead screw, a moving block, and a mounting block. When bending steel pipes of different diameters, it is often necessary to replace the fixed column and the bending column. For large-diameter steel pipes, the distance between the fixed column and the bending column needs to be changed, and the position of the clamping components should also be changed accordingly. Therefore, by rotating the third lead screw, the moving block and the bending column can be moved, which can change the distance between the fixed column and the bending column. Rotating the bending column can move the mounting block, which can change the position of the clamping components. Attached Figure Description

[0034] Reference Figure 1-7 This utility model provides a high-precision CNC bending machine, comprising a mounting block 1, a first moving groove 2 inside the mounting block 1, a second moving groove 3 at the top of the first moving groove 2, and two second moving grooves 3. A first lead screw 4 is movably mounted on the inner wall of the mounting block 1, a moving plate 5 is threadedly connected to the outer surface of the first lead screw 4, and two locking pins 6 are fixedly connected to the upper surface of the moving plate 5. A clamping member 7 is provided above the mounting block 1, and two clamping members 7 are provided. An inclined groove 8 is opened at the bottom of the clamping member 7, and the locking pins 6 are located inside the inclined groove 8. A limit block 9 is fixedly connected to the side wall of the clamping member 7. The mounting block 1, the first lead screw 4, the moving plate 5, the locking pins 6, the clamping member 7, and the limit block 9 together constitute a clamping assembly. There are multiple limit blocks 9, which are slidably mounted on the side wall of the mounting block 1. Rotating the handle 11, thereby... The rotating torsion plate 10 and the first lead screw 4 rotate, which in turn drives the moving plate 5 to move. When it is necessary to clamp the steel pipe, the moving plate 5 moves away from the torsion plate 10, which in turn drives the locking pin 6 to move away from the torsion plate 10. Due to the presence of the inclined groove 8, the adjacent clamping parts 7 will move closer to each other, which can fix the steel pipe well. When it is not necessary to clamp the steel pipe, the moving plate 5 can be moved closer to the torsion plate 10. The torsion plate 10 is fixedly connected to the side wall of the first lead screw 4. The handle 11 is fixedly connected to the side of the torsion plate 10 away from the first lead screw 4. Rotating the handle 11 can drive the torsion plate 10 and the first lead screw 4 to rotate. The inner wall of the mounting block 1 is fixedly connected to the sliding rod 12. The sliding rod 12 can restrict the movement of the moving plate 5 and prevent the moving plate 5 from deviating during the movement. The moving plate 5 is sleeved on the outer surface of the sliding rod 12.

[0035] A workbench 13 is provided below the mounting block 1. A first groove 14 is formed on the upper surface of the workbench 13. A second lead screw 15 is movably installed on the inner wall of the first groove 14. A first handle 16 is fixedly connected to the side wall of the second lead screw 15. Rotating the first handle 16 can drive the second lead screw 15 to rotate, thereby driving the mounting block 1 to move. The mounting block 1 is threadedly connected to the outer surface of the second lead screw 15. A connecting block 17 is fixedly connected to the side wall of the workbench 13. A fixing post 18 is fixedly connected to the upper surface of the connecting block 17. The fixing post 18 is used to cooperate with the bending post 26 to the steel pipe. For bending, a mounting bracket 19 is fixedly connected to the lower surface of the worktable 13, and a motor 20 is fixedly connected to the upper surface of the mounting bracket 19. The motor 20 drives the rotating block 21 to rotate. The output end of the motor 20 is fixedly connected to the rotating block 21, which is movably mounted on the lower surface of the connecting block 17. When bending steel pipes of different diameters, it is often necessary to replace the fixing column 18 and the bending column 26. For larger diameter steel pipes, the distance between the fixing column 18 and the bending column 26 needs to be changed, and the position of the clamping assembly should also be changed accordingly. Therefore, by rotating the third lead screw... 23 can move the moving block 25 and the bending column 26, changing the distance between the fixed column 18 and the bending column 26. Rotating the bending column 26 can move the mounting block 1, changing the position of the clamping assembly. The upper surface of the rotating block 21 has a second groove 22, and a third lead screw 23 is movably installed on the inner wall of the second groove 22. A second handle 24 is fixedly connected to the side wall of the third lead screw 23, and the outer surface of the third lead screw 23 is threadedly connected to the moving block 25. When it is necessary to adjust the position of the bending column 26, rotating the second handle 24 drives the third lead screw 23 to rotate, thereby moving the mounting block 1. The movable block 25 and bending column 26 move. The bending column 26 is fixedly connected to the upper surface of the movable block 25. The bending column 26 and the movable block 25 are connected by bolts for easy replacement. The lower surface of the worktable 13 is fixedly connected to the support legs 27, which can support the worktable 13. There are four support legs 27. When you want to bend the steel pipe, first place the steel pipe between the fixed column 18 and the bending column 26, then clamp the steel pipe. Then the motor 20 works to drive the rotating block 21, the movable block 25 and the bending column 26 to rotate, so that the steel pipe can be bent.

[0036] Working principle: Rotating handle 11 causes the torsion plate 10 and the first lead screw 4 to rotate, which in turn moves the moving plate 5. When clamping the steel pipe, the moving plate 5 moves away from the torsion plate 10, causing the locking pin 6 to move away from the torsion plate 10. Due to the presence of the inclined groove 8, adjacent clamping parts 7 move closer together, thus securing the steel pipe. When clamping the steel pipe is no longer needed, the moving plate 5 moves closer to the torsion plate 10. When bending steel pipes of different diameters, it is often necessary to replace the fixing post 18 and the bending post 26, and the large straight... The movement of the steel pipe will cause a change in the distance between the fixed column 18 and the bending column 26, and the position of the clamping component should also change accordingly. Therefore, by rotating the third lead screw 23, the moving block 25 and the bending column 26 can be moved, which can change the distance between the fixed column 18 and the bending column 26. Rotating the bending column 26 can move the mounting block 1, which can change the position of the clamping component. When you want to bend the steel pipe, first place the steel pipe between the fixed column 18 and the bending column 26, then clamp the steel pipe, and then the motor 20 works to drive the rotating block 21, the moving block 25 and the bending column 26 to rotate, which can bend the steel pipe.
