Description

Technical Field

[0001] This utility model relates to the field of straight pipe machine technology, specifically a straight pipe machine with an automatic unloading device. Background Technology

[0002] Pipe straightening machines, also known as straightening equipment, are used for the repair and maintenance of steel pipes. After long-term use and storage, steel pipes are prone to bending problems. Pipe straightening machines can straighten bent and deformed pipes, thereby restoring the performance of the steel pipes, improving the efficiency of steel pipe repair, and reducing labor and time costs.

[0003] After the pipe straightening machine straightens the steel pipe, it is generally necessary to manually remove the steel pipe from the straightening machine. This not only results in low work efficiency, but also in the long-term production process, frequent manual handling of steel pipes can easily lead to fatigue and safety accidents. Therefore, a pipe straightening machine with an automatic unloading device is needed. Utility Model Content

[0023] Please see Figure 1-4 One embodiment of this utility model provides: a straightening machine with an automatic unloading device, comprising: a straightening machine body 1, and further comprising...

[0024] Straightening wheel 2 is located at one end inside the main body 1 of the straightening machine. Supporting wheels 3 are evenly arranged inside the main body 1 of the straightening machine below the straightening wheel 2. A steel pipe body 4 passes through between the straightening wheel 2 and the supporting wheels 3.

[0025] The steel pipe body 4 that needs to be straightened passes between the straightening roller 2 and the support roller 3, and the bent steel pipe is straightened by the squeezing action;

[0026] A movable frame 9 is provided above the support wheel 3. The straightening wheels 2 are evenly distributed in the movable frame 9. A second lead screw 22 is provided in the main body 1 of the straightening machine on one side of the movable frame 9, and a second drive block 21 is sleeved on the second lead screw 22. One end of the second drive block 21 is connected to the movable frame 9.

[0027] A second servo motor 23 is fixed inside the straightening machine body 1 above the second lead screw 22, and the output end of the second servo motor 23 is connected to the second lead screw 22.

[0028] The second servo motor 23 can drive the second lead screw 22 to rotate, causing the second drive block 21 to move up and down along the second lead screw 22, thereby adjusting the distance between the straightening wheel 2 and the support wheel 3, which is applicable to the straightening work of steel pipe body 4 with different diameters.

[0029] A guide rod 24 is provided inside the straight pipe machine body 1 on the side of the movable frame 9 away from the second lead screw 22, and the end of the movable frame 9 close to the guide rod 24 is slidably sleeved with the guide rod 24 through a guide sleeve to guide and limit the movable frame 9;

[0030] The frame 5 is located inside the main body 1 of the straightening machine at one end away from the straightening wheel 2. The frame 5 is equipped with a first lead screw 7, and a first drive block 6 is sleeved on the first lead screw 7. The bottom of the first drive block 6 is equipped with a turntable 15 through a third servo motor 14.

[0031] The housing 13 is located at the output end of the cylinder 16 at the bottom of the turntable 15, and the bottom end inside the housing 13 is rotatably connected to the first clamp 12 and the second clamp 17 via a rotating shaft, and the first clamp 12 and the second clamp 17 are respectively provided with a meshing first gear 19 and a second gear 20.

[0032] Guide wheels 11 are evenly arranged inside the main body 1 of the straight pipe machine on one side of the support wheel 3. The guide wheels 11 and the support wheel 3 are located on the same horizontal line, and the top surface of the guide wheels 11 is in contact with the bottom surface of the steel pipe body 4.

[0033] After straightening, the main body 4 of the steel pipe enters the guide wheel 11. When it moves to the central position, the cylinder 16 drives the housing 13, the first clamp 12 and the second clamp 17 to move down to both sides of the main body 4 of the steel pipe.

[0034] Electric cylinder 18 is disposed inside housing 13, and the output end of electric cylinder 18 is connected to the top end of first clamp 12 via a coupling.

[0035] The output end of the electric cylinder 18 drives the first clamp 12 to rotate through the coupling, causing the first gear 19 on the first clamp 12 to rotate. The second gear 20 meshes with the first gear 19, causing the second gear 20 and the second clamp 17 to rotate, thereby clamping the steel pipe body 4 through the first clamp 12 and the second clamp 17. At the same time, the third servo motor 14 drives the turntable 15 to rotate, causing the gripped steel pipe body 4 to rotate 90°.

[0036] One end of the frame 5 is fixed with a first servo motor 8, and the output end of the first servo motor 8 is connected to the first lead screw 7.

[0037] The third servo motor 14 drives the turntable 15 to rotate, causing the gripped steel pipe body 4 to rotate 90°. Then the first servo motor 8 drives the first lead screw 7 to rotate, causing the first drive block 6 to move along the first lead screw 7.

[0038] Furthermore, a trough 10 is provided inside the straightening machine body 1 on one side of the guide wheel 11. The steel pipe body 4 after being gripped is moved above the trough 10 for unloading, so that the straightened steel pipe body 4 can be automatically returned to the trough 10 for collection. This can reduce manual intervention, reduce labor intensity, and achieve continuous and efficient processing of the steel pipe body 4.

[0039] The specific models and specifications of the first servo motor 8, the second servo motor 23, the third servo motor 14, the cylinder 16, and the electric cylinder 18 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail here.

[0040] Working principle: In this embodiment, the steel pipe body 4 requiring straightening passes between the straightening wheel 2 and the support wheel 3. The bent steel pipe is straightened by compression. The second servo motor 23 drives the second lead screw 22 to rotate, causing the second drive block 21 to move up and down along the second lead screw 22. This adjusts the distance between the straightening wheel 2 and the support wheel 3, making it suitable for straightening steel pipe bodies 4 of different diameters. After straightening, the steel pipe body 4 enters the guide wheel 11. When it reaches the central position, the cylinder 16 drives the housing 13, the first clamp 12, and the second clamp 17 to move down to both sides of the steel pipe body 4. The output end of the electric cylinder 18 drives the first clamp 12 to rotate via a connecting shaft, causing the second drive block 21 to move up and down along the second lead screw 22. The first gear 19 on the clamp 12 rotates, and the second gear 20 meshes with the first gear 19, causing the second gear 20 and the second clamp 17 to rotate. Thus, the steel pipe body 4 is clamped by the first clamp 12 and the second clamp 17. At the same time, the third servo motor 14 drives the turntable 15 to rotate, causing the gripped steel pipe body 4 to rotate 90°. Then, the first servo motor 8 drives the first lead screw 7 to rotate, causing the first drive block 6 to move along the first lead screw 7, moving the gripped steel pipe body 4 to the top of the tank 10 for unloading. This allows the straightened steel pipe body 4 to be automatically returned to the tank 10 for collection, reducing manual intervention, lowering labor intensity, and achieving continuous and efficient processing of the steel pipe body 4.
