A metal pipe bending internal support clamping mechanism

Abstract

This utility model belongs to the field of pipe clamping technology, specifically a metal steel pipe bending internal support clamping mechanism, including a mounting base and a recessed groove at the upper end. The clamping mechanism is fixed to the bending equipment by a fixing plate on the mounting base. A linear track is installed in the recessed groove, and a handwheel is fixed to one end of the linear track. A sliding slide is provided on the linear track. It can be understood that this utility model uses a motor to drive the side clamping plate and the inner support rod to move synchronously. The side clamping plate radially clamps the metal steel pipe, while the inner support rod provides internal support at the clamped position of the metal steel pipe. This combination of internal support and external clamping ensures clamping stability even for thin-walled metal steel pipes, preventing deformation. Furthermore, by setting up a pipe rack, support plate, and axial guide seat, the metal steel pipe can be quickly positioned on the clamping mechanism and precisely cooperate with the side clamping plate and inner support rod, thereby facilitating clamping.

Description

Technical Field

[0001] This utility model belongs to the field of pipe clamping technology, and in particular relates to a metal steel pipe bending inner support clamping mechanism. Background Technology

[0002] Metal pipe bending clamping refers to the process of firmly fixing the steel pipe near the bending point using specialized clamps or molds during pipe bending. This clamping is crucial, as it precisely controls the movement of the steel pipe under strong external forces, ensuring that the bend occurs at the predetermined position and preventing slippage, twisting, or unintended deformation during bending. The clamps typically provide strong radial restraint, tightly "holding" the pipe wall when the yield point of the steel pipe is exceeded and plastic bending deformation occurs, ensuring that it can only bend along the path set by the mold, thus achieving precise shaping to meet specific angle and curvature requirements.

[0003] Because steel pipes require a very large radial clamping force to ensure pipe stability, but some pipes are thinner, they may leave indentations during radial clamping, or even deform the clamping position, which is not conducive to clamping thinner pipes.

[0004] To address the aforementioned issues, this application proposes a metal steel pipe bending inner support clamping mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a metal steel pipe bending inner support clamping mechanism, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a metal steel pipe bending internal support clamping mechanism, comprising a mounting base and a recessed groove at the upper end. The clamping mechanism is fixed to the bending equipment via a fixing plate on the mounting base. A linear track is installed in the recessed groove, and a handwheel is fixed to one end of the linear track. A sliding slide is provided on the linear track, and a clamping seat is fixed on the slide. Two symmetrical side clamping plates are slidably provided on the clamping seat for radial clamping of the metal steel pipe. An axial guide seat is also fixed on the clamping seat, and an inner support rod is slidably provided in the axial guide seat to form support inside the metal steel pipe clamped by the side clamping plates. The two side clamping plates and one inner support rod are synchronously driven by a motor.

[0008] Furthermore, the clamp is internally equipped with a bidirectional lead screw driven by a motor, and the lower end of the side clamp is fixed with an internal threaded sleeve that is threadedly engaged with the bidirectional lead screw.

[0009] Furthermore, the axial guide seat is provided with a rotating gear inside, and the inner support rod is provided with a rack that meshes with the gear. The gear and the bidirectional lead screw are linked by a pulley assembly.

[0010] Furthermore, a tube frame is provided at the end of the clamp away from the guide seat, and a support plate is fixed on the clamp. The metal steel pipe overlaps the tube frame and the support plate and abuts against the gear.

[0011] Furthermore, a support rod is fixed to the lower end of the pipe rack, and the support rod is fixedly installed to the side of the clamp via a mounting plate.

[0012] Furthermore, the side clamps near the metal steel pipe and the upper part of the support plate are both arc-shaped structures.

[0013] Furthermore, the pipe rack is arranged in a V-shape.

[0014] This utility model has the following beneficial effects:

[0015] This utility model uses a motor to drive the side clamping plate and the inner support rod to move synchronously. The side clamping plate radially clamps the metal steel pipe, and the inner support rod forms support inside the clamped position of the metal steel pipe. Even if the metal steel pipe has a thin wall, the combination of internal support and external clamping can ensure clamping stability while avoiding deformation of the metal steel pipe.

[0016] This utility model, by setting up a pipe rack, a support plate, and an axial guide seat in combination, enables the metal steel pipe to be quickly positioned on the clamping mechanism and to accurately cooperate with the side clamping plate and the inner support rod, thereby achieving the purpose of easy clamping.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figures 1-4 As shown, this utility model is a metal steel pipe bending internal support clamping mechanism, including a mounting base 1 and a groove 11 opened at the upper end. The clamping mechanism is fixed to the bending equipment through a fixing plate 12 on the mounting base 1. A linear track 2 is installed in the groove 11. A handwheel 21 is fixed at one end of the linear track 2. A sliding slide 22 is provided on the linear track 2. In this embodiment, a screw is provided inside the linear track 2 and driven by the handwheel 21. The bottom of the slide 22 is provided with a thread that engages with the screw thread. The sliding of the slide 22 on the linear track 2 can adjust the axial length between the slide 22 and the metal steel pipe 7 according to the length of the metal steel pipe 7, so as to adapt to the bending clamping of metal steel pipes 7 of different lengths.

[0028] Specifically, a clamping seat 3 is fixed on the slide 22, and two symmetrical side clamping plates 33 are slidably provided on the clamping seat 3 for radial clamping of the metal steel pipe 7. An axial guide seat 4 is also fixed on the clamping seat 3. An inner support rod 5 is slidably provided in the axial guide seat 4 to form support inside the metal steel pipe 7 clamped by the side clamping plates 33. The two side clamping plates 33 and one inner support rod 5 are synchronously driven by the motor 311.

[0029] Specifically, the clamp 3 is equipped with a bidirectional lead screw 31 driven by a motor 311, and the lower end of the side clamp 33 is fixed with an internal threaded sleeve 32 that is threadedly engaged with the bidirectional lead screw 31.

[0030] In this embodiment, there are two internal threaded sleeves 32 and two side clamps 33. The two internal threaded sleeves 32 are respectively engaged with the two ends of the bidirectional screw 31. When the bidirectional screw 31 rotates, it spirals with the internal threaded sleeves 32, causing the two internal threaded sleeves 32 to move inward or outward at the same time, thereby forming a clamping and release of the metal steel pipe 7.

[0031] Specifically, the axial guide seat 4 is equipped with a rotating gear 41 inside, and the inner support rod 5 is equipped with a rack 51 that meshes with the gear 41. The gear 41 and the double-acting lead screw 31 are linked by a pulley group 42.

[0032] When in use, the bidirectional lead screw 31 rotates and drives the side clamping plate 33 to clamp or release through the spiral of the internal threaded sliding sleeve 32. At the same time, the bidirectional lead screw 31 also drives the gear 41 to mesh with the rack 51 through the pulley group 42, realizing the reciprocating sliding of the inner support rod 5. The support plate 34 is used for external clamping of the metal steel pipe 7, and the inner support rod 5 forms a support on the inside of the clamping position of the metal steel pipe 7 to prevent the metal steel pipe 7 from deforming.

[0033] Specifically, in order to facilitate the rapid positioning and support of the metal steel pipe 7 on the clamping mechanism, a pipe rack 6 is provided at the end of the clamping seat 3 away from the guide seat 4. A support plate 34 is fixed on the clamping seat 3. The metal steel pipe 7 overlaps the pipe rack 6 and the support plate 34 and abuts against the gear 41.

[0034] Furthermore, a support rod 61 is fixed at the lower end of the pipe rack 6. The support rod 61 is fixedly installed to the side of the clamp 3 through the mounting plate 62. Both the pipe rack 6 and the support rod 61 are made of steel bars bent and welded together. The mounting plate 62 is welded and fixed to the support rod 61 and fixed to the side of the clamp 3 by bolts.

[0035] To ensure sufficient contact area and friction with the curved surface of the metal pipe 7, the side of the side clamp 33 near the metal pipe 7 and the upper end of the support plate 34 are both curved structures.

[0036] To facilitate the rapid positioning of the metal steel pipe 7, the pipe rack 6 is arranged in a V-shape.

[0037] It is understood that this utility model uses a motor to drive the side clamping plate and the inner support rod to move synchronously. The side clamping plate radially clamps the metal steel pipe, while the inner support rod provides internal support at the clamped position of the metal steel pipe. This combination of internal support and external clamping ensures clamping stability while preventing deformation, even for thin-walled metal steel pipes. Furthermore, by setting up a pipe rack, support plate, and axial guide seat, the metal steel pipe can be quickly positioned on the clamping mechanism and precisely engaged with the side clamping plate and inner support rod, thus facilitating clamping.

[0038] One specific application of this embodiment is that the mounting base 1 is fixedly mounted on the bending machine via the fixing plate 12.

[0039] like Figure 1 The side clamp 33 shown is in the open state, and the inner support rod 5 is in the fully reset state. At this time, the metal steel pipe 7 is placed on the pipe rack 6 and the support plate 34, and then the front end of the metal steel pipe 7 is pushed axially to abut against the axial guide seat 4. At this time, the metal steel pipe 7 and the inner support rod 5 are coaxial.

[0040] Start the motor 311. The motor 311 drives the double-acting lead screw 31 and the internal threaded sleeve 32 to spiral and cause the two side clamps 33 to move closer to the metal steel pipe 7 until a clamping force is formed. While the side clamps, the side clamps 33 drive the gear 41 to rotate under the action of the pulley group 42. The gear 41 drives the inner support rod 5 to extend forward in the axial guide seat 4 through meshing with the rack 51. The inner support rod 5 enters the interior of the metal steel pipe 7 and forms a support on the inside of the clamping position of the side clamps 33, so that the metal steel pipe 7 can be bent.

[0041] After bending is completed, the motor 311 is started in reverse, and the two side clamps 33 move outward synchronously. The inner support rod 5 is disengaged from the metal steel pipe 7, and the bent metal steel pipe 7 is taken out.
