Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic steel pipe expanding machines, in particular to a hydraulic steel pipe expanding machine. Background Art

[0002] Steel pipe flaring is a metal forming process used to change the diameter of the end of a steel pipe to facilitate connection to other pipes or components. This operation is often performed when manufacturing complex piping systems or repairing existing pipes. Flaring ensures that pipe connections have the proper size match, providing stronger sealing performance and structural integrity. In addition, flaring can also be used to create pipe joints of a specific shape.

[0003] A steel pipe flaring machine is a mechanical device specifically used to expand the diameter of the end of a steel pipe. This machine usually includes a fixture, a rotating mechanism, a flaring tool, and a hydraulic cylinder. The fixture holds the steel pipe in place, while the hydraulic cylinder and flaring tool are used to continue flaring one end of the pipe. The rotating mechanism also rotates the pipe to ensure that the pipe is heated more evenly during flaring, thereby improving the quality and accuracy of the flaring.

[0004] Although the existing technology can complete the expansion of steel pipes to achieve a tight connection, prevent leakage, and withstand a certain amount of pressure, it is difficult for the working group to allocate an appropriate steel pipe rotation speed when processing steel pipes of different radii. When the rotation speed is slow, the steel pipe heating efficiency is slow, resulting in reduced processing efficiency and heat loss. When the rotation speed is fast, it is easy to cause heat concentration or uneven distribution, resulting in reduced processing accuracy and affecting processing quality.

[0005] Therefore, a hydraulic steel pipe expanding machine is proposed to address the above problems. Utility Model Content

When the rotation speed is fast, it is easy to cause heat concentration or uneven distribution, resulting in a decrease in processing accuracy and affecting the processing quality.

[0026] Specific examples are given below.

[0027] See also Figures 1-4 The utility model provides a hydraulic steel pipe expanding machine, comprising a base 1, a support plate 2 is fixedly mounted on the top of the base 1, a three-jaw chuck 3 is rotatably mounted on one end of the support plate 2, a flaring tool 4 is rotatably mounted on the other side of the three-jaw chuck 3, a hydraulic cylinder 5 is slidably mounted on one end of the flaring tool 4, the hydraulic cylinder 5 is fixedly mounted on the top of the base 1, a first motor 6 is mounted on one side of the support plate 2, the first motor 6 is fixedly mounted on the top of the base 1, and a support assembly for supporting the steel pipe is provided on the top of the base 1;

[0028] The supporting assembly includes a second motor 7 arranged at the top of the base 1, and a first bevel gear 8 is installed at one end of the second motor 7. A driving assembly is provided on one side of the first bevel gear 8, and a second bevel gear 9 is meshed and installed on the top of the first bevel gear 8. A first screw rod 10 is fixedly installed on the top of the second bevel gear 9, and a support seat 11 is threadedly installed on the outer wall of the first screw rod 10; by setting the supporting assembly, after the steel pipe is fixed, the second motor 7 can be started so that the second motor 7 drives the support seat 11 to move in the direction close to the steel pipe through the first bevel gear 8, the second bevel gear 9 and the first screw rod 10, so that the support seat 11 abuts against the bottom end of the steel pipe, providing support for the steel pipe, avoiding the problem that when the steel pipe rotates, the middle section of the steel pipe is affected by torque and gravity, which is prone to deformation and damage, thereby affecting the processing quality of the steel pipe, improving the protection of the steel pipe, thereby improving the stability of the steel pipe during the processing, and thus improving the processing effect of the steel pipe.

[0029] Further, such as Figure 1-4As shown, the driving assembly includes a second screw rod 12 arranged on one side of the first bevel gear 8, and the driving slider 13 is rotatably installed at one end of the second screw rod 12 away from the first bevel gear 8, and the top of the driving slider 13 is provided with an adjusting assembly; by setting the driving assembly, when the adjusting support assembly provides support and protection for the steel pipe, the first bevel gear 8 drives the second screw rod 12 to rotate, and the second screw rod 12 drives the driving slider 13 to move, so that the driving slider 13 drives the adjusting assembly to perform the adjustment operation, avoiding the problem that when processing different steel pipes, the staff finds it difficult to control the adjusting assembly to the appropriate position, causing the steel pipe to rotate faster or slower, which affects the processing of the steel pipe, so that the adjusting assembly can automatically drive and adjust according to the actual size of the steel pipe, thereby enhancing the accuracy and effectiveness of the adjusting assembly, thereby improving the processing effect of the device on the steel pipe.

[0030] Further, such as Figure 1-4 As shown, the adjusting component includes a synchronous rod 14 arranged at the top of the driving slider 13, and two adjusting blocks 15 are fixedly installed on the outer wall of the synchronous rod 14, and a synchronous belt 16 is slidably installed on the inner wall of the adjusting block 15. The end of the synchronous belt 16 close to the flaring tool 4 is sleeved with a first rotating shaft 17, and the other end of the synchronous belt 16 is sleeved with a second rotating shaft 18. One end of the second rotating shaft 18 is fixedly installed with a third bevel gear 19, and one side of the third bevel gear 19 is meshed with a fourth bevel gear 20. One side of the fourth bevel gear 20 is fixedly installed with a rotating rod 21, and one end of the rotating rod 21 is fixedly installed with a first driving gear 22, and one side of the first driving gear 22 is meshed with a second driving gear 23, and the second driving gear 23 is fixedly installed on one side of the three-jaw chuck 3; by setting the adjusting component, when the radius of the steel pipe to be processed is large, the driving slider 13 drives the synchronous rod 14 to move in the direction close to the first bevel gear 8, and the synchronous rod 14 drives the synchronous rod 14 through the adjusting block 15 The step belt 16 moves, so that the speed of the first rotating shaft 17 driving the second rotating shaft 18 to rotate through the synchronous belt 16 decreases, and when the radius of the steel pipe to be processed is small, the driving slider 13 drives the synchronous rod 14 to move in the direction close to the first motor 6, so that the first rotating shaft 17 drives the second rotating shaft 18 to rotate through the synchronous belt 16 to increase the speed, thereby adjusting the rotation speed of the steel pipe through the third bevel gear 19, the fourth bevel gear 20, the rotating rod 21, the first driving gear 22 and the three-jaw chuck 3, avoiding the difficulty of the working group personnel in allocating the appropriate steel pipe rotation speed when processing steel pipes of different radii. When the rotation speed is slow, it is easy to cause the steel pipe heating efficiency to be slow, thereby causing a decrease in processing efficiency and heat loss. When the rotation speed is fast, it is easy to cause heat concentration or uneven distribution, thereby causing a decrease in processing accuracy and affecting the processing quality. The applicability of the device is improved, the stability of the steel pipe during the processing is improved, and the processing quality and accuracy of the steel pipe are improved.

[0031] Further, such as Figure 3-4As shown, guide rails are provided on both sides of the driving slider 13, and the guide rails are fixedly installed on the top of the base 1; by providing the guide rails, the guiding and limiting effects can be improved when the driving slider 13 moves, so that the driving slider 13 moves along the guide rails, avoiding the driving slider 13 from easily deflecting when the driving slider 13 moves, thereby driving the synchronization rod 14 and the adjustment block 15 to deflect, so that the adjustment block 15 pulls the synchronization belt 16, causing the synchronization belt 16 to bend and over-tighten, resulting in the rotation of the synchronization belt 16 being hindered, affecting the normal operation of the adjustment component, and shortening the service life of the synchronization belt 16, thereby improving the stability and reliability of the device and extending the service life of the synchronization belt 16.

[0032] Further, such as Figure 1-3 As shown, the first rotating shaft 17 and the second rotating shaft 18 are in opposite directions, and the busbar of the first rotating shaft 17 away from the second rotating shaft 18 and the busbar of the second rotating shaft 18 away from the first rotating shaft 17 are parallel to each other; by setting the first rotating shaft 17 and the second rotating shaft 18 in opposite directions, the first rotating shaft 17 can change the speed of the second rotating shaft 18 through the synchronous belt 16. When one end of the synchronous belt 16 moves from the large end to the small end from the first rotating shaft 17, the other end of the synchronous belt 16 moves from the small end to the large end of the second rotating shaft 18. At this time, the speed of the second rotating shaft 18 increases. When one end of the synchronous belt 16 moves from the small end to the large end of the first rotating shaft 17, the synchronous belt 16 The other end moves from the larger end of the second rotating shaft 18 to the smaller end. At this time, the rotation speed of the second rotating shaft 18 is reduced, and by setting the generatrix of the first rotating shaft 17 away from the second rotating shaft 18 and the generatrix of the second rotating shaft 18 away from the first rotating shaft 17 to be parallel to each other, the rotation radius of the synchronous belt 16 can be kept unchanged, so that the synchronous belt 16 is always kept in a taut state, avoiding the synchronous belt 16 from being easily loosened locally during movement, thereby affecting the rotation rate of the second rotating shaft 18, and finally affecting the rotation rate of the steel pipe, resulting in the problem of reduced steel pipe processing quality, improving the stability and reliability of the adjustment component, and thus improving the steel pipe processing quality.

[0033] Further, such as Figure 1-4 As shown, discs are provided at both ends of the first rotating shaft 17 and the second rotating shaft 18; by providing the discs, the movement of the synchronous belt 16 can be limited, thereby preventing the synchronous belt 16 from easily falling off the first rotating shaft 17 or the second rotating shaft 18 when moving to both ends of the first rotating shaft 17 and the second rotating shaft 18, affecting the operation of the adjustment component, and then causing the steel pipe to stop rotating, resulting in a decrease in the processing accuracy and quality of the steel pipe, thereby improving the stability and reliability of the adjustment component.

[0034] Further, such as Figure 4As shown, the distance between the two ends of the guide rail is greater than the maximum distance between the bottom end of the support seat 11 and the bottom end of the second bevel gear 9; when the support seat 11 moves to the highest horizontal position, the driving slider 13 can still move in the guide rail, avoiding the problem of motion interference caused by the driving slider 13 abutting against one end of the guide rail when the support seat 11 has not moved to the highest point when the distance between the two ends of the guide rail is small, thereby hindering the movement of the support seat 11, thereby improving the stability and reliability of the device.

[0035] Working principle: When the steel pipe needs to be expanded, one end of the steel pipe is abutted against one side of the three-jaw chuck 3 and fixed. At this time, the second motor 7 is started, so that the second motor 7 drives the first bevel gear 8 to rotate, the first bevel gear 8 drives the second bevel gear 9 to rotate, the second bevel gear 9 drives the first screw rod 10 to rotate, and the first screw rod 10 drives the support seat 11 to move in the direction close to the steel pipe, so that the support seat 11 abuts against the bottom end of the steel pipe, providing support and protection for the steel pipe. At the same time, the first bevel gear 8 drives the second screw rod 12 to rotate, and the second screw rod 12 drives the driving slider 13 to move along the guide rail, and the driving slider 13 drives the synchronous rod 14 to move, and the synchronous rod 14 drives the adjusting block 15 to move, and the adjusting block 15 drives the synchronous belt 16 to move, so that the first rotating shaft 17 changes the rotation speed of the second rotating shaft 18 through the synchronous belt 16;

[0036] After adjusting according to the actual size of the steel pipe, start the first motor 6, so that the first motor 6 drives the first rotating shaft 17 to rotate, the first rotating shaft 17 drives the synchronous belt 16 to rotate, the synchronous belt 16 drives the second rotating shaft 18 to rotate, the second rotating shaft 18 drives the third bevel gear 19 to rotate, the third bevel gear 19 drives the fourth bevel gear 20 to rotate, the fourth bevel gear 20 drives the rotating rod 21 to rotate, the rotating rod 21 drives the first driving gear 22 to rotate, the first driving gear 22 drives the second driving gear 23 to rotate, and the second driving gear 23 drives the three-jaw chuck 3 to rotate, and the three-jaw chuck 3 drives the steel pipe to rotate, so that the steel pipe is heated evenly during the expanding process, thereby improving the processing accuracy and effect of the steel pipe. At this time, start the hydraulic cylinder 5, so that the hydraulic cylinder 5 pushes the expanding tool 4 to extrude and shape one end of the steel pipe, thereby completing the steel pipe expanding operation.
