Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, specifically a multi-roller adjustment device for a steel pipe straightening machine. Background Technology

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. It uses straightening rollers to compress the bars and other materials to change their straightness. The skew roller straightening machine is specially designed for straightening steel with round cross-sections. The straightening rollers intersect the round material at an angle. When the rollers rotate, the round material rotates and moves forward at the same time. The bending trajectory of the rollers on the round material is spiral-shaped, making it a straightening machine that straightens in all directions.

[0003] Straightening machines generally need to straighten steel of different diameters, so the distance between the combined rollers needs to be changed frequently to adapt to various pipe materials. In the prior art, straightening machines adjust the distance between the rollers by setting corresponding adjustment structures for each straightening roller, thereby increasing or decreasing the distance between the combined rollers to straighten various pipe materials. However, in the adjustment process, multiple adjustment structures need to be adjusted sequentially, which is time-consuming. To address the above problems, the inventors have proposed a multi-roller adjustment device for steel pipe straightening machines to solve the above problems. Utility Model Content

[0004] To address the problem that current steel pipe straightening machines require sequential adjustment of the corresponding adjustment structures for each straightening roller during the adjustment process, which is time-consuming, this utility model aims to provide a multi-roller adjustment device for steel pipe straightening machines.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-roller adjustment device for a steel pipe straightening machine, comprising a housing, a main straightening roller rotatably disposed inside the housing, a ring sleeve fixedly connected to the side wall of the housing on one side of the main straightening roller, a movable cylinder slidably connected to the opening of the ring sleeve, a toothed plate fixedly connected to the bottom surface of the movable cylinder, a concave frame provided on the end face of the movable cylinder, a secondary straightening roller rotatably connected to the concave opening of the concave frame, the secondary straightening roller corresponding to the main straightening roller, a horizontal shaft provided outside the housing, a worm gear and a gear fixedly connected to the side wall of the horizontal shaft, the gear corresponding to and meshing with the toothed plate.

[0006] Preferably, a feed inlet is provided through one side of the housing, and a discharge outlet is provided through the other side of the housing, with the feed inlet and discharge outlet corresponding to each other. When straightening a bent steel pipe, one end of the bent steel pipe is inserted into the feed inlet. After the bent steel pipe is straightened by the main straightening roller and the secondary straightening roller, the steel pipe can be removed from the housing through the discharge outlet. The rotation of the main straightening roller is a mature existing technology and is not the focus of this device, so it is used directly here without further explanation. A support plate is rotatably connected to the side wall of the horizontal shaft, and the side wall of the support plate is connected to the housing. The outer wall of the housing is fixedly connected, and the support plate is used to support the rotation of the horizontal shaft. A motor is installed on the outside of the housing, and a worm is fixedly connected to the output shaft end of the motor. The worm and the worm wheel are corresponding and meshing. A base is provided on the side wall of the motor, and the side wall of the base is fixedly connected to the outer wall of the housing. The motor is installed through the base. When the motor is started, the worm rotates under the action of the motor output shaft. Through the meshing of the worm and the worm wheel, the horizontal shaft can be rotated, which in turn causes the multiple gears fixedly sleeved on the horizontal shaft to rotate.

[0007] Preferably, a guide plate is fixedly connected to the outer wall of the movable cylinder, a guide groove is provided on the inner wall of the ring, the guide plate is located in the guide groove, and the guide plate is slidably connected to the guide groove. A rectangular groove is provided on one side of the guide groove on the inner wall of the ring, the toothed plate is located in the rectangular groove, and the groove opening size of the rectangular groove is larger than the cross-sectional size of the toothed plate. When the horizontal shaft rotates, it can drive the gear to rotate. Through the meshing of the gear and the toothed plate, and under the action of the guide plate and the guide groove, the movable cylinder can move smoothly. Then, the concave frame can drive the secondary straightening roller to move laterally to adjust the distance between the secondary straightening roller and the main straightening roller. The spacing is adjusted to accommodate straightening operations on steel pipes of different diameters. Several straightening rollers are arranged in an array from left to right. The number of rollers can be increased or decreased according to usage requirements. When the motor is started, the worm rotates under the action of the motor output shaft. Through the meshing of the worm and worm wheel, the horizontal shaft rotates, causing multiple gears fixedly mounted on the horizontal shaft to rotate and mesh with the toothed plates at the bottom of multiple movable cylinders. This allows the movable cylinders to move smoothly, adjusting the distance between the straightening rollers and the main straightening rollers simultaneously, avoiding manual adjustment one by one and saving time.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the worm gear mechanism enables the horizontal shaft to rotate, which in turn enables multiple gears to rotate and mesh with the toothed plates at the bottom of multiple movable cylinders, thereby allowing the movable cylinders to move smoothly. The concave frame enables multiple straightening rollers to move laterally together to adjust the distance between the straightening rollers and the main straightening rollers, avoiding manual adjustment one by one, thus saving operation time. In addition, the worm gear mechanism has a self-locking function, which can prevent displacement after adjustment. Furthermore, the multiple gears rotate coaxially through the horizontal shaft, thereby ensuring synchronous adjustment of multiple rollers. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3As shown, this utility model provides a multi-roller adjustment device for a steel pipe straightening machine, including a housing 1. A main straightening roller 4 is rotatably arranged inside the housing 1. A ring 9 is fixedly connected to the side wall of the housing 1 and to one side of the main straightening roller 4. A movable cylinder 12 is slidably connected to the opening of the ring 9. A toothed plate 14 is fixedly connected to the bottom surface of the movable cylinder 12. A concave frame 18 is provided on the end face of the movable cylinder 12. A secondary straightening roller 19 is rotatably connected to the concave opening of the concave frame 18. The secondary straightening roller 19 corresponds to the main straightening roller 4. A horizontal shaft 5 is provided outside the housing 1. A worm gear 7 and a gear 8 are fixedly connected to the side wall of the horizontal shaft 5. The gear 8 corresponds to and meshes with the toothed plate 14.

[0016] A feed inlet 2 is provided through one side of the box body 1, and a discharge outlet 3 is provided through the other side of the box body 1, with the feed inlet 2 and the discharge outlet 3 corresponding to each other.

[0017] By adopting the above technical solution, when straightening the bent steel pipe, one end of the bent steel pipe is inserted into the feed port 2. After the bent steel pipe is straightened by the main straightening roller 4 and the auxiliary straightening roller 19, the steel pipe can be removed from the box 1 through the discharge port 3. The rotation of the main straightening roller 4 is an existing mature technology and is not the focus of this device. It is used directly here and will not be described in detail.

[0018] A guide plate 13 is fixedly connected to the outer wall of the movable cylinder 12. A guide groove 10 is provided on the inner wall of the ring 9. The guide plate 13 is located in the guide groove 10 and is slidably connected to the guide groove 10. A rectangular groove 11 is provided on the inner wall of the ring 9 and on one side of the guide groove 10. The toothed plate 14 is located in the rectangular groove 11, and the groove opening size of the rectangular groove 11 is larger than the cross-sectional size of the toothed plate 14.

[0019] By adopting the above technical solution, when the horizontal shaft 5 rotates, it can drive the gear 8 to rotate. Through the meshing of the gear 8 and the toothed plate 14, and under the action of the guide plate 13 and the guide groove 10, the movable cylinder 12 can move smoothly. Then, the concave frame 18 can drive the straightening roller 19 to move laterally, so as to adjust the distance between the straightening roller 19 and the main straightening roller 4, so as to be suitable for straightening steel pipes of different diameters. There are several straightening rollers 19, which are arranged in an array from left to right. The number of straightening rollers 19 can be increased or decreased according to usage requirements. When the motor 15 is started, the worm 17 rotates under the action of the output shaft of the motor 15. Through the meshing of the worm 17 and the worm wheel 7, the horizontal shaft 5 can be rotated, which in turn causes the multiple gears 8 fixedly sleeved on the horizontal shaft 5 to rotate and mesh with the toothed plates 14 at the bottom of the multiple movable cylinders 12. This allows the movable cylinders 12 to move smoothly, thereby adjusting the distance between the straightening rollers 19 and the main straightening roller 4 at the same time, avoiding manual adjustment one by one and saving time.

[0020] A support plate 6 is rotatably connected to the side wall of the horizontal axis 5, and the side wall of the support plate 6 is fixedly connected to the outer side wall of the box body 1.

[0022] A motor 15 is installed on the outside of the housing 1. A worm 17 is fixedly connected to the output shaft end of the motor 15. The worm 17 corresponds to and meshes with the worm wheel 7. A base 16 is provided on the side wall of the motor 15. The side wall of the base 16 is fixedly connected to the outer side wall of the housing 1.

[0023] By adopting the above technical solution, the motor 15 is installed on the base 16. When the motor 15 is started, the worm 17 rotates under the action of the output shaft of the motor 15. Through the meshing of the worm 17 and the worm wheel 7, the horizontal shaft 5 can be rotated, which in turn causes the multiple gears 8 fixedly sleeved on the horizontal shaft 5 to rotate.

[0024] Working principle: When the position of the straightening roller 19 needs to be adjusted, the worm 17 rotates under the action of the output shaft of the motor 15 when the motor 15 is started. Through the meshing of the worm 17 and the worm wheel 7, the horizontal shaft 5 can be rotated, which in turn causes the multiple gears 8 fixedly sleeved on the horizontal shaft 5 to rotate and mesh with the toothed plates 14 at the bottom of the multiple movable cylinders 12. Under the action of the guide plate 13 and the guide groove 10, the movable cylinders 12 can move smoothly. Then, the multiple straightening rollers 19 can be moved laterally together through the concave frame 18 to adjust the distance between the straightening rollers 19 and the main straightening roller 4, avoiding manual adjustment one by one and saving time. After the position adjustment of the straightening roller 19 is completed, one end of the steel pipe to be straightened is inserted into the feed inlet 2. The bent steel pipe is straightened by the main straightening roller 4 and the straightening roller 19. After straightening, the steel pipe can be removed from the box 1 through the discharge outlet 3.
