Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe clamping devices, and more specifically, to a steel pipe fixing and clamping mechanism for a steel pipe straightening machine. Background Technology

[0002] A steel pipe straightening machine is a mechanical device used to straighten steel pipes that have become bent or deformed due to various reasons (such as rolling, transportation, storage, etc.). It is widely used in steel pipe manufacturing, construction and other industries.

[0003] Patent CN212494986U discloses a steel pipe clamping and fixing device for a straightening machine, including a straightening machine. A rectangular base is fixedly connected to the right side of the lower surface of the straightening machine. A rectangular groove is opened at the right end of the upper surface of the rectangular base. The inner wall of the rectangular groove has a rectangular groove recessed on both the left and right sides. This steel pipe clamping and fixing device for a straightening machine moves two threaded rods within the rectangular grooves by rotating them. The movement of the threaded rods drives two rectangular vertical blocks to move. The movement of the two rectangular vertical blocks drives two circular horizontal bars to move. The movement of the two circular horizontal bars drives two arc-shaped plates to move, thereby allowing the distance between arc-shaped plates to be adjusted at will. This allows the user to adjust the distance according to the actual situation, making it easier to clamp steel pipes of different sizes and adjust the clamping tightness, thus increasing the flexibility of the device.

[0004] However, this type of pipe clamping and fixing device for straightening machines still has the following drawbacks: During pipe straightening operations, some pipes have multiple bends and require straightening. The current operating procedure involves releasing the clamping device after each straightening operation, unfixing the pipe, pushing it into the straightening equipment to align the next straightening position, and then clamping it again. This series of cumbersome steps causes frequent interruptions during the straightening process, reducing overall straightening efficiency to some extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a steel pipe fixing and clamping mechanism for a steel pipe straightening machine, so as to solve the problem that in the steel pipe straightening operation of the prior art, some steel pipes are bent in multiple places, and after each straightening, they need to be loosened, pushed forward and clamped again, which is cumbersome, causes straightening interruption and reduces efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a steel pipe fixing and clamping mechanism for a steel pipe straightening machine, comprising...

[0007] A straightening machine, wherein a base is fixedly installed on the lower right surface of the straightening machine, a groove is provided in the middle of the base, and a roller is rolled inside the groove. A support platform is fixedly installed on the top of the roller, and a clamping mechanism is provided on the top of the support platform.

[0008] The traction feeding assembly includes a transverse limiting frame plate and a U-shaped plate. The bottom of the transverse limiting frame plate is attached to the upper surface of the straightener and is installed with the straightener bolts at both ends. A serrated plate is fixedly installed on the middle of the side of the transverse limiting frame plate away from the support platform. The side end of the U-shaped plate is fixedly installed on the bottom surface of the support platform. The inner surface of the U-shaped plate is slidably installed on the outer surface of the transverse limiting frame plate. A motor is fixedly installed on the top of the U-shaped plate. A gear is fixedly sleeved on the output end of the motor and meshes with the serrated plate.

[0009] It also includes a cleaning component, which is located at the feed inlet on the right side of the straightening machine.

[0010] The traction feeding assembly further includes a connecting plate and a rotating wheel. The side end of the connecting plate is fixedly installed on the surface of the bottom of the support platform, and the end end is slidably installed on the lower surface of the transverse limiting frame plate. The outer surface of the end of the rotating wheel is rotatably installed on the inner surface of the bottom of the support platform, and the outer surface of the rotating wheel is rotatably installed on the inner surface of the side of the transverse limiting frame plate near the support platform.

[0011] The cleaning assembly includes a U-shaped support frame and a second motor. The side of the U-shaped support frame is fixedly installed in the middle of the side of the straightening machine near the base. A rotating cylinder is rotatably installed on the inner surface of the top of the U-shaped support frame. A gear ring is fixedly sleeved on the outer surface of the end of the rotating cylinder. The second motor is fixedly installed on the upper surface of the side of the U-shaped support frame away from the straightening machine. A second gear is fixedly sleeved on the output end of the second motor. The second gear meshes with the gear ring. Multiple electric telescopic rods are fixedly installed on the outer surface of the middle of the rotating cylinder. Each end of the multiple electric telescopic rods is fixedly installed with a brush plate. Auxiliary rods are fixedly installed on the outer surfaces of both ends of the brush plate. The outer surfaces of the auxiliary rods are slidably installed with the inner surface of the rotating cylinder.

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

[0013] In the above scheme, by setting up a traction feeding component, when the steel pipe is straightened by the straightening machine, the operator clamps and fixes one end of the pipe through the clamping mechanism on the top of the support platform. After straightening one position, the motor can be started, and the gear fixedly connected to the output end of the motor rotates. The gear moves along the surface of the meshing sawtooth plate, pulling the externally fixed U-shaped plate to slide along the outer edge of the transverse limiting frame plate. This causes the support platform fixedly installed on the side of the top of the U-shaped plate to slide along the top of the straightening machine. Thus, the traction feeding component feeds the steel pipe clamped by the clamping mechanism on the top of the support platform into the straightening machine. This eliminates the need to loosen, push, and re-clamp after each straightening operation, improving efficiency.

[0014] In the above scheme, by setting up a cleaning component, during the steel pipe feeding process, the operator can control the extension or retraction of the electric telescopic rod, pushing the brush plate fixedly installed at its end to move towards the axis of the rotating cylinder until the brush plate contacts the surface of the steel pipe. At this time, the second motor is started, and the second gear fixedly sleeved with the output end of the second motor rotates, driving the meshing gear ring to rotate, which in turn drives the fixedly sleeved rotating cylinder to rotate along the inner surface of the U-shaped support frame. The electric telescopic rod and auxiliary rod installed on it drive the brush plate installed at its end to rotate along the surface of the steel pipe, thereby cleaning the dust, rust and other impurities on the surface of the steel pipe to a certain extent, reducing the possibility of these impurities remaining inside the equipment during subsequent straightening processing, thus improving the practicality of the device.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a steel pipe fixing and clamping mechanism for a steel pipe straightening machine, including...

[0023] A straightening machine 1 has a base 2 fixedly installed on its lower right surface. A groove is provided in the middle of the base 2, and a roller 4 is rolled inside the groove. A support platform 3 is fixedly installed on the top of the roller 4, and a clamping mechanism 5 is provided on the top of the support platform 3.

[0024] The traction feeding assembly 6 includes a transverse limiting frame plate 60 and a U-shaped plate 62. The bottom of the transverse limiting frame plate 60 is attached to the upper surface of the straightener 1 and is bolted to the straightener 1 by bolts at both ends. A serrated plate 61 is fixedly installed on the middle of the side of the transverse limiting frame plate 60 away from the support table 3. The side end of the U-shaped plate 62 is fixedly installed on the bottom surface of the support table 3. The inner surface of the U-shaped plate 62 is slidably installed on the outer surface of the transverse limiting frame plate 60. A motor 64 is fixedly installed on the top of the U-shaped plate 62. A gear 65 is fixedly sleeved on the output end of the motor 64. The gear 65 meshes with the serrated plate 61.

[0025] By setting rollers 4 and rotating wheels 66, while the support platform 3 connected by the U-shaped plate 62 moves laterally, the rollers 4 installed at the bottom of the support platform 3 roll along the groove in the middle of the straightener 1, and the connecting plate 63 slides along the lower surface of the transverse limiting frame plate 60. The rotating wheels 66 rotate inside the bottom of the support platform 3 and along the inner edge of the transverse limiting frame plate 60, which improves the stability of movement and reduces the friction between the support platform 3 and the straightener 1.

[0026] It also includes a cleaning component 7, which is located at the feed inlet on the right side of the straightener 1.

[0027] The traction feeding assembly 6 also includes a connecting plate 63 and a rotating wheel 66. The side end of the connecting plate 63 is fixedly installed on the bottom surface of the support platform 3, and the end end is slidably installed on the lower surface of the transverse limiting frame plate 60. The outer surface of the end of the rotating wheel 66 is rotatably installed on the inner surface of the bottom of the support platform 3, and the outer surface of the rotating wheel 66 is rotatably installed on the inner surface of the side of the transverse limiting frame plate 60 near the support platform 3.

[0028] The cleaning component 7 includes a U-shaped support frame 70 and a second motor 73. The side of the U-shaped support frame 70 is fixedly installed in the middle of the side of the straightener 1 near the base 2. A rotating cylinder 71 is rotatably installed on the inner surface of the top of the U-shaped support frame 70. A toothed ring 72 is fixedly sleeved on the outer surface of the end of the rotating cylinder 71. The second motor 73 is fixedly installed on the upper surface of the side of the U-shaped support frame 70 away from the straightener 1. A second gear 74 is fixedly sleeved on the output end of the second motor 73. The second gear 74 meshes with the toothed ring 72. Multiple electric telescopic rods 75 are fixedly installed on the outer surface of the middle part of the rotating cylinder 71. Brush plates 76 are fixedly installed at the ends of the multiple electric telescopic rods 75. Auxiliary rods 77 are fixedly installed on the outer surfaces of both ends of the brush plates 76. The outer surfaces of the auxiliary rods 77 are slidably installed with the inner surface of the rotating cylinder 71.

[0029] By setting up the cleaning component 7, during the steel pipe feeding process, the operator can control the electric telescopic rod 75 to extend or retract, pushing the brush plate 76 fixedly installed at its end to move towards the axis of the rotating cylinder 71 until the brush plate 76 contacts the surface of the steel pipe. At this time, the control motor 73 starts, and the gear 74 fixedly sleeved with the output end of the motor 73 rotates, driving the meshing gear ring 72 to rotate, which in turn drives the fixedly sleeved rotating cylinder 71 to rotate along the inner surface of the U-shaped support frame 70. The electric telescopic rod 75 and auxiliary rod 77 installed on it drive the brush plate 76 installed at its end to rotate along the surface of the steel pipe, thereby cleaning the dust, rust and other impurities on the surface of the steel pipe to a certain extent, reducing the possibility of these impurities remaining inside the equipment during subsequent straightening treatment, thus improving the practicality of the device.

[0030] The working process of this utility model is as follows:

[0031] When straightening steel pipes using straightening machine 1, the operator clamps one end of the pipe using clamping mechanism 5 on top of support platform 3. After straightening one position, motor 64 is started, and gear 65, which is fixedly connected to the output end of motor 64, rotates. Gear 65 moves along the surface of meshing sawtooth plate 61, pulling externally fixed U-shaped plate 62 to slide along the outer edge of transverse limiting frame plate 60. This causes support platform 3, which is fixedly installed on the side of top of U-shaped plate 62, to slide along the top of straightening machine 1. Thus, the traction feeding assembly 6 feeds the steel pipe clamped by clamping mechanism 5 on top of support platform 3 into the straightening machine 1. This eliminates the need to release, push, and re-clamp after each straightening operation, improving efficiency.
