[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. The straightening machine uses straightening rollers to compress the bars and other materials to change their straightness. Generally, there are two rows of straightening rollers, but the number varies. There are also two-roller straightening machines, which rely on the change of the angle between the two rollers to straighten materials of different diameters. The main types include pressure straightening machines, balance roller straightening machines, shoe roller straightening machines, rotary reverse bending straightening machines, etc.

[0003] Currently, when adjusting the distance between the two straightening rollers of a traditional straightening machine, the screw is usually driven by manually turning a handwheel, which moves the straightening roller seat to adjust the distance to accommodate metal pipes of different diameters. This adjustment operation is cumbersome and laborious, thus affecting the straightening efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a metal tube straightening device, which solves the problem that the operation of manually turning a handwheel to drive a screw, which in turn pushes the straightening roller seat to move and adjust the spacing to adapt to metal tubes of different diameters, is cumbersome and laborious, thus affecting the straightening efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal tube straightening device, comprising a workbench, a support frame connected below the workbench, side plates connected to both sides below the workbench, support plates connected to both sides above the workbench, multiple fixed platforms mounted on the top of the workbench by bolts, multiple guide rods connected to the top of the workbench, a threaded rod rotatably connected to the bottom of the workbench by bearings, a working motor fixedly installed below the workbench, the output shaft of the working motor connected to the threaded rod, a movable plate mounted on the threaded rod, connecting frames connected to both sides of the movable plate, and fixed plates connected to the connecting frames;

[0006] The fixed plate has multiple inclined slots. A movable platform is slidably mounted on the guide rod. Sliding sleeves are connected to both sides of the movable platform. Connecting rods are connected to the sliding sleeves. Both the fixed platform and the movable platform are skewed and are rotatably connected to straightening rollers via bearings. A drive motor is fixedly mounted on one side of both the fixed platform and the movable platform. The output shaft of the drive motor is connected to the straightening roller. An arc plate is mounted on the support plate. An insertion hole is opened on the top of the support plate. First springs are connected inside both sides of the support plate. A hook plate is connected to one end of the first spring.

[0007] As a further embodiment of this utility model: a sponge pad is connected to the arc plate, a buckle groove is provided on both sides of the arc plate, and a plug rod is connected to both sides below the arc plate, and the plug rod is inserted into the plug hole.

[0008] As a further embodiment of this utility model: a threaded sleeve is connected to the movable plate, the threaded rod is threadedly engaged with the threaded sleeve, and the connecting rod slides in the inclined groove.

[0009] As a further embodiment of this utility model: a guide groove is provided on the side plate, and the connecting frame slides in the guide groove.

[0010] As a further embodiment of this utility model: the sliding sleeve is slidably connected to the guide rod, a second spring is sleeved on the guide rod, one end of the second spring is connected to the worktable, the other end of the second spring is connected to the sliding sleeve, and an anti-slip pad is connected below the support frame.

[0011] As a further embodiment of this utility model: the hook plate is U-shaped in shape, one end of the hook plate connected to the first spring slides in the support plate, and the other end of the hook plate is engaged with the buckle groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This metal pipe straightening equipment consists of a working motor, a threaded rod, a moving plate, a threaded sleeve, a connecting frame, a fixed plate, an inclined groove, and a connecting rod. The operator starts the working motor to rotate the threaded rod, causing the moving plate to move along the threaded rod through the threaded engagement of the threaded sleeve and the threaded rod. This causes the connecting frame to move along the guide groove, pulling the fixed plate horizontally. The moving fixed plate then pushes the connecting rod through the inclined groove, causing the connecting rod to move the movable table, allowing the sliding sleeve to slide on the guide rod. This adjusts the distance between the fixed table and the movable table, changing the spacing between the two straightening rollers to accommodate metal pipes of different diameters. The operation is simple, requires no manual intervention, and improves adjustment and straightening efficiency.

[0014] 2. This metal tube straightening equipment consists of a support plate, an arc plate, a sponge pad, a hook plate, a first spring, a locking groove, a drive motor, and straightening rollers. The drive motor rotates the straightening rollers. Due to the skewed design of the fixed and movable platforms, the metal tube is driven by the two straightening rollers, causing it to gradually roll and move horizontally between them, thus completing the straightening process. The support plate and arc plate support the metal tube, ensuring smooth contact with the straightening rollers on the fixed platform. The sponge pad on the arc plate cushions the contact force and removes dust. Pulling the hook plate extends the first spring, causing the hook plate to disengage from the locking groove, allowing for easy removal of the arc plate and convenient replacement by the operator.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a metal tube straightening device, including a workbench 1, a support frame 2 connected below the workbench 1, and side plates 3 connected to both sides below the workbench 1. The side plates 3 are provided with guide grooves 26, and the connecting frame 10 slides in the guide grooves 26. The connecting frame 10 is guided and restricted by the guide grooves 26, thereby preventing the connecting frame 10 and the moving plate 9 from rotating and tilting, and promoting the smooth movement of the moving plate 9.

[0022] The workbench 1 is connected to two support plates 4 on both sides above it. Multiple fixed platforms 5 are bolted to the top of the workbench 1. Multiple guide rods 6 are connected to the top of the workbench 1. A threaded rod 7 is rotatably connected to the bottom of the workbench 1 via bearings. A working motor 8 is fixedly installed below the workbench 1. The output shaft of the working motor 8 is connected to the threaded rod 7. A movable plate 9 is installed on the threaded rod 7. A threaded sleeve 25 is connected to the movable plate 9. The threaded rod 7 and the threaded sleeve 25 are threadedly engaged. The connecting rod 15 slides in the inclined groove 12. The inclined groove 12 can push the connecting rod 15 to move when the fixed plate 11 moves, thereby driving the sliding sleeve 14 to slide on the guide rod 6, thereby adjusting the distance between the two straightening rollers 16 to improve applicability.

[0023] Connecting brackets 10 are connected to both sides of the movable plate 9. A fixed plate 11 is connected to the connecting bracket 10. Multiple inclined slots 12 are opened on the fixed plate 11. A movable platform 13 is slidably installed on the guide rod 6. Sliding sleeves 14 are connected to both sides of the movable platform 13. The sliding sleeves 14 are slidably connected to the guide rod 6. A second spring 27 is sleeved on the guide rod 6. One end of the second spring 27 is connected to the worktable 1, and the other end of the second spring 27 is connected to the sliding sleeve 14. An anti-slip pad 28 is connected below the support frame 2. The movement of the movable platform 13 can be guided by the guide rod 6, while the anti-slip pad 28 below the support frame 2 can increase friction and prevent accidental slippage.

[0024] A connecting rod 15 is connected to the sliding sleeve 14. Both the fixed platform 5 and the movable platform 13 are designed with an skewed shape and are connected to the straightening roller 16 through bearings. A drive motor 17 is fixedly installed on one side of both the fixed platform 5 and the movable platform 13. The output shaft of the drive motor 17 is connected to the straightening roller 16. An arc plate 18 is installed on the support plate 4. A sponge pad 22 is connected to the arc plate 18. The arc plate 18 has a snap groove 23 on both sides. Insert rods 24 are connected to the lower sides of the arc plate 18. The insert rods 24 are inserted into the insertion holes 19. The insertion of the insert rods 24 into the insertion holes 19 makes it convenient for workers to quickly position and install the arc plate 18. The sponge pad 22 can provide cushioning and prevent scratches when the metal tube rolls.

[0025] An insertion hole 19 is provided on the top of the support plate 4. A first spring 20 is connected to the inside of both sides of the support plate 4. A hook plate 21 is connected to one end of the first spring 20. The hook plate 21 is U-shaped. The end of the hook plate 21 connected to the first spring 20 slides in the support plate 4. The other end of the hook plate 21 is engaged with the buckle groove 23. The elastic force of the first spring 20 can cause the hook plate 21 to be locked into the buckle groove 23 after the hook plate 21 is released, thereby fixing the arc plate 18. The operation is simple and convenient for workers to replace the arc plate 18 with the sponge pad 22 that is damaged.

[0026] The working principle of this utility model is as follows:

[0027] During operation, the drive motor 17 rotates the straightening roller 16, and the working motor 8 rotates the threaded rod 7, causing the moving plate 9 to move along the threaded rod 7 via the threaded sleeve 25. This causes the connecting frame 10 to move the fixed plate 11 along the guide groove 26. When the fixed plate 11 moves, the inclined groove 12 pushes the connecting rod 15, which in turn causes the connecting rod 15 to drive the movable table 13, making the sliding sleeve 14 slide on the guide rod 6. This adjusts the distance between the fixed table 5 and the movable table 13, changing the spacing between the two straightening rollers 16 to accommodate metal pipes of different diameters. Due to the skewed design of the fixed table 5 and the movable table 13, the metal pipe can be driven by the two straightening rollers 16. Specifically, the metal pipe is first subjected to the rotational force of the lower straightening roller 16 and rolls on the straightening roller 16 on the fixed table 5. Simultaneously, it is subjected to the rotational force of the upper straightening roller 16 and continuously moves within the gap. This causes the metal pipe to roll and move between the two straightening rollers 16, thus completing the straightening work.
