[0001] This utility model relates to the field of steel pipe processing equipment technology, and in particular to a steel pipe straightening device. Background Technology

[0002] Steel pipe straightening machines are mainly used to straighten and repair bent and deformed steel pipes. They are often used in the processing of steel pipes to process bent steel pipes.

[0003] A search revealed Chinese Patent Publication No. CN221311980U, which discloses a steel pipe straightening device. The device includes: a base; a first support block, a fixing plate, and a second support block fixedly connected to the upper end of the base; an outlet at the center of the side end of the first support block; a rotating mechanism rotatably connected to the center of the outlet; an adjusting gear at the lower end of the rotating mechanism; a third motor fixedly connected to one end of the first support block; two mounting plates slidably connected to the upper end of the base; a plurality of conveying rollers rotatably connected to the upper ends of the two mounting plates; a support plate rotatably connected to the upper ends of the plurality of conveying rollers; a plurality of first motors fixedly connected to the upper ends of the support plates; and an inlet at the center of the side end of the second support block, penetrating the second support block. This device can straighten steel pipes of different diameters multiple times, improving the straightening effect, and automatically rotates the steel pipe, reducing workload and simplifying operation.

[0004] While the above method has the advantage of straightening steel pipes of different diameters, its limiting effect on the steel pipe is relatively poor in actual use, causing the steel pipe to shake continuously during the straightening process and affecting the straightening effect.

[0005] Therefore, there is an urgent need to provide a steel pipe straightening device to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the above-mentioned prior art in the actual use of steel pipes, which is poor in limiting effect, causing the steel pipes to shake continuously during the straightening process and affecting the straightening effect. This utility model provides a steel pipe straightening device.

[0007] To solve the above-mentioned technical problems, the present invention provides a steel pipe straightening device, including a base plate, an inlet and an outlet disposed on both sides of the base plate, a straightening component disposed opposite to each other on the top of the base plate, and a limit component disposed between the inlet and the outlet.

[0008] The limiting component includes a fixed shell fixedly disposed at the top center of the base plate, a bidirectional lead screw movably disposed inside the fixed shell, a sliding sleeve disposed outside the bidirectional lead screw, an upper pressure member disposed at the top of the sliding sleeve, and a first connecting member disposed between the upper pressure member and the sliding sleeve. A second connecting member is disposed between the sliding sleeve and the straightening member, and the second connecting member has the same structure as the first connecting member.

[0009] The present invention is further configured such that: a U-shaped frame is installed on the top of the base plate, and the inlet and outlet are respectively installed on the inner surface of the U-shaped frame on both sides;

[0010] The upper pressure component is movably connected between the two U-shaped frames.

[0011] The present invention is further configured such that: the straightening component includes a lower support plate movably disposed on the top of the base plate, an upper support plate disposed on the top of the lower support plate, and a straightening roller disposed between the upper support plate and the lower support plate, wherein a driving device is disposed on the top of the straightening roller.

[0012] The present invention is further configured such that: the limiting component also includes a transmission unit disposed on the bidirectional lead screw;

[0013] The transmission unit includes a rotating rod movably connected to the inner side of the base plate, a driving gear mounted on the outer side of the rotating rod, and a driven gear meshing with the top of the driving gear. The driven gear is mounted on the outer side of the bidirectional lead screw.

[0014] The present invention is further configured such that: the upper pressing component includes a lifting plate movably connected between two U-shaped frames, a support rod installed at the bottom of the lifting plate, and a straightening wheel movably connected at the bottom of the support rod.

[0015] The present invention is further configured such that: the first connecting member includes one end of a movable rod movably connected to the inner side of the lower support plate or the bottom of the lifting plate, and one end of an extension rod movably disposed at the other end of the movable rod. The other end of the extension rod is movably connected to the outer side or top surface of the sliding sleeve, and an elastic element is provided between the inner wall of the movable rod and the end of the extension rod.

[0016] The present invention is further configured such that: a support base is installed at the top center of the fixed shell, and the support base is arranged coaxially with the inlet and outlet of the pipe;

[0017] The horizontal distance from the straightening component to the support base and the vertical distance from the upper pressing component to the support base are equal.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention uses a limiting component to insert one end of a steel pipe into the inlet and out of the outlet. A rotating rod drives a drive gear, which in turn meshes with the driven gear, causing a bidirectional lead screw to rotate. Under the action of the threaded pair, a sliding sleeve slides along the length of the lead screw. As the sleeve slides, it works with the first and second connecting parts to bring the upper pressure component and the straightening component closer to the steel pipe. The elastic component and extension rod work together to ensure stability of the first and second connecting parts during the pulling process. This, combined with the straightening roller, straightening wheel, and support base, provides longitudinal and lateral limiting for the steel pipe, preventing it from wobbling during straightening and improving the straightening effect.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 5A steel pipe straightening device includes a base plate 1, an inlet 2 and an outlet 3 disposed on both sides of the base plate 1, a straightening component 4 disposed opposite to each other on the top of the base plate 1, and a limiting component 5 disposed between the inlet 2 and the outlet 3. The limiting component 5 is used to limit the upper and side parts of steel pipes of different specifications to prevent the steel pipes from shaking during the straightening process.

[0028] The limiting component 5 includes a fixed shell 51 fixedly disposed at the top center of the base plate 1, a bidirectional lead screw 52 movably disposed inside the fixed shell 51, a sliding sleeve 53 disposed outside the bidirectional lead screw 52, ​​an upper pressure member 54 disposed on the top of the sliding sleeve 53, a first connecting member 55 disposed between the upper pressure member 54 and the sliding sleeve 53, and a second connecting member 56 disposed between the sliding sleeve 53 and the straightening member 4. The second connecting member 56 has the same structure as the first connecting member 55.

[0029] Among them, a U-shaped frame 11 is installed on the top of the base plate 1, and the inlet 2 and outlet 3 are respectively installed on the inner surface of the U-shaped frame 11 on both sides.

[0030] The upper pressure component 54 is movably connected between the two U-shaped frames 11.

[0031] The straightening component 4 includes a lower support plate 41 movably disposed on the top of the base plate 1, an upper support plate 42 disposed on the top of the lower support plate 41, and a straightening roller 43 disposed between the upper support plate 42 and the lower support plate 41. The top of the straightening roller 43 is provided with a driving device (not shown in the figure), which is a motor.

[0032] The limiting component 5 also includes a transmission unit 57 disposed on the bidirectional lead screw 52;

[0033] The transmission unit 57 includes a rotating rod 571 movably connected to the inner side of the base plate 1, a driving gear 572 installed on the outer side of the rotating rod 571, and a driven gear 573 meshing with the top of the driving gear 572. The driven gear 573 is installed on the outer side of the bidirectional lead screw 52. Preferably, one end of the rotating rod 571 extends through to the outer side of the base plate 1, and a handle is welded to one end of the rotating rod 571.

[0034] The upper pressing component 54 includes a lifting plate 541 movably connected between the two U-shaped frames 11, a support rod 542 installed at the bottom of the lifting plate 541, and a straightening wheel 543 movably connected at the bottom of the support rod 542.

[0035] The first connecting member 55 includes one end of a movable rod 551 movably connected to the inner side of the lower support plate 41 or the bottom of the lifting plate 541, and one end of an extension rod 552 movably disposed at the other end of the movable rod 551. The other end of the extension rod 552 is movably connected to the outer side or top surface of the sliding sleeve 53. An elastic element 553 is provided between the inner wall of the movable rod 551 and the end of the extension rod 552. Preferably, the elastic element 553 is a spring.

[0036] Among them, a support base 6 is installed at the top center of the fixed shell 51, and the support base 6 is coaxially arranged with the inlet 2 and the outlet 3;

[0037] The horizontal distance from the straightening component 4 to the support base 6 and the vertical distance from the upper pressing component 54 to the support base 6 are equal, so that when the transmission unit 57 is working, the upper pressing component 54 and the straightening component 4 move the same distance toward the steel pipe.

[0038] In use, one end of the steel pipe is first inserted into the inlet 2 and exited from the outlet 3. Then, the rotating rod 571 drives the drive gear 572 to rotate. Since the drive gear 572 meshes with the driven gear 573, it drives the bidirectional lead screw 52 to rotate. Under the action of the threaded pair, the sliding sleeve 53 slides along the length of the bidirectional lead screw 52. When the sliding sleeve 53 slides, it will drive the upper pressure member 54 and the straightening member 4 to move closer to the steel pipe through the first connecting member 55 and the second connecting member 56 respectively. The elastic member 553 cooperates with the extension rod 552 to make the first connecting member 55 and the second connecting member 56 relatively stable during the pulling process. Thus, together with the straightening roller 43, the straightening wheel 543 and the support seat 6, the steel pipe is longitudinally and laterally limited, avoiding the steel pipe from shaking during the straightening process and improving the straightening effect.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
