Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending device technology, specifically a column bending auxiliary device. Background Technology
[0002] A column bending aid is a device used to improve the efficiency and accuracy of metal column bending operations. Its structure typically includes an adjustable clamping mechanism that can firmly fix column materials of different specifications and prevent deviation during bending. It is also equipped with flexible bending aid mechanisms, such as movable positioning blocks or angle adjustment components, which can precisely control the bending angle and position and reduce human error. Some devices also integrate limit modules or intelligent sensors to monitor the bending process in real time and avoid over-bending or material damage.
[0003] The utility model with announcement number CN221790688U discloses a bending device for processing sound barrier columns. This utility model sets up a support mechanism so that a shaft motor drives two limiting plates to move closer together. The two limiting plates, in a close-moving state, clamp and limit the other end of the column to be processed supported on the bracket. This can prevent the column from swaying left and right when one end is subjected to compressive force. Moreover, the distance between the two limiting plates can be adjusted, so that the position of the two limiting plates can be adjusted according to the size of the column to be processed, making it more practical and effectively improving the quality of the finished sound barrier columns.
[0004] The aforementioned device completes the bending process of the column by extrusion between the upper and lower dies. During bending, the upper die applies downward pressure to bend the column. Due to this characteristic, the two ends of the column will be relatively raised after being compressed. The limiting plate clamps and fixes the column by clamping. This results in the end of the column not being able to bend and raise normally when it is bent under pressure, and the limiting plate generates a relatively strong friction, which can easily cause friction damage to the surface of the column and is not conducive to the normal compression deformation of the column. In addition, when the column is placed, one end overlaps the support. Since the column is placed at an angle, it only contacts the corner of the support. When the column is bent under pressure, the contact area with the corner of the support is small, which can easily cause the contact part of the column to be crushed and affect its strength. Therefore, in order to solve the above problems, a column bending auxiliary device is proposed. Utility Model Content
[0005] To address the technical problems in comparative technologies where limiting and fixing measures affect the normal compressive deformation of the column, leading to easy wear and tear, and where bending can cause the column surface to be indented due to pressure, thus affecting strength, the present invention aims to provide a column bending auxiliary device.
[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0007] A column bending auxiliary device includes a base plate with a bending frame installed at one end, on which a bending mechanism for bending the column is installed; a bracket installed at the other end of the base plate, including a set of symmetrically arranged support legs and rollers rotatably mounted on the support legs; and two anti-deviation mechanisms, located on both sides of the bracket, each including a guide frame with symmetrically arranged anti-deviation shafts slidably installed inside, the guide frame driving the anti-deviation shafts to synchronously move closer to or away from each other.
[0008] In one possible implementation, the guide frame includes a frame body with a sliding groove inside, and end pieces for closing the sliding groove are fixedly provided at both ends of the frame body. A bidirectional threaded screw is provided in the sliding groove, and its two ends are rotatably connected to the end pieces. The threads on both sides of the bidirectional threaded screw are opened in opposite directions.
[0009] In one possible implementation, the anti-deviation shaft includes a threaded cylinder slidably disposed in a groove, which is threadedly connected to a bidirectional threaded screw, and a vertically upward-arranged shaft is fixedly connected to the threaded cylinder.
[0010] In one possible implementation, the idler roller includes an inner shaft with its two ends rotatably connected to corresponding support legs, and an outer sleeve is fitted over its exterior.
[0011] In one possible implementation, the inner shaft surface is provided with a plurality of slots arranged in a circumferential array, and the inner wall of the outer sleeve is fixedly provided with a plurality of ribs corresponding to the slots.
[0012] In one possible implementation, the bending mechanism includes a hydraulic cylinder fixedly mounted on a bending frame, and also includes a lower die and an upper die, wherein the lower die is fixedly mounted on the bending frame and the upper die is fixedly mounted on the shaft end of the hydraulic cylinder.
[0013] In one possible implementation, two symmetrically arranged guide rods are slidably mounted on the bending frame, with their bottom ends fixedly connected to the upper mold.
[0014] In one possible implementation, both the lower mold and the upper mold are provided with centrally located positioning grooves.
[0015] In summary, this utility model has the following beneficial technical effects:
[0016] Since the column needs to bend and deform in a vertical plane during bending, the bracket supports the column to allow for deformation space. The two sets of anti-deviation mechanisms limit the position of the column, preventing it from shifting left or right during bending. They also fix the position of the column by fixing it at two points in a straight line, making it less prone to shifting during placement. The anti-deviation mechanism includes a guide frame and symmetrically arranged anti-deviation shafts. The spacing of the anti-deviation shafts can be freely adjusted to accommodate the limiting of columns of different sizes. Since the anti-deviation shafts slide in contact with the column, they hardly constrain the deformation of the column and prevent column wear.
[0017] In addition, the bracket includes support legs and rollers, and the rollers are composed of an inner shaft and an outer sleeve. Because the outer sleeve has a smooth surface and a large size, it can effectively support the end of the column. When the column is bent under pressure, the outer sleeve will not shear the column, thus avoiding the formation of dents on the column surface. Attached Figure Description

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0025] like Figure 1As shown, this embodiment provides a column bending auxiliary device, including a base plate 1, one end of which is equipped with a bending frame 2, and a bending mechanism 3 for bending columns is installed on the bending frame 2; a bracket 5, which is installed at the other end of the base plate 1, including a set of symmetrically arranged support legs 51, and rollers 52 rotatably installed on the support legs 51; and an anti-deviation mechanism 4, which is provided in two sets, located on both sides of the bracket 5 respectively. The anti-deviation mechanism 4 includes a guide frame 41, inside which symmetrically arranged anti-deviation shafts 42 are slidably installed. The guide frame 41 is used to drive the anti-deviation shafts 42 to move closer or further away synchronously.
[0026] Based on the above scheme, since the column needs to bend and deform in the vertical plane when it is bent in the bending mechanism 3, the bracket 5 supports the column to allow for deformation space. However, the column may sway left and right during bending, which may affect the normal bending process. Therefore, two sets of anti-deviation mechanisms 4 are set up. These mechanisms can limit the position of the column and prevent it from shifting left and right during bending. At the same time, they can fix the placement position of the column by fixing a straight line at two points, so that it is not easy to shift during placement. The spacing of the anti-deviation shaft 42 in the anti-deviation mechanism 4 can be freely adjusted to accommodate the limiting of columns of different sizes. Since the anti-deviation shaft 42 slides in contact with the column, it will hardly constrain the deformation of the column and will not cause wear on the column. In addition, the roller 52 can effectively support the end of the column. When the column is bent under pressure, it will not shear the column and avoid extrusion dents on the column surface.
[0027] The guide frame 41 includes a frame body 411 with a sliding groove 412 inside. End pieces 413 for closing the sliding groove 412 are fixedly installed at both ends of the frame body 411. A bidirectional threaded screw 414 is provided in the sliding groove 412, with both ends rotatably connected to the end pieces 413. The threads on both sides of the bidirectional threaded screw 414 are in opposite directions. The anti-deviation shaft 42 includes a threaded cylinder 421 slidably disposed in the sliding groove 412, threadedly connected to the bidirectional threaded screw 414. A vertically upward-arranged shaft 422 is fixedly connected to the threaded cylinder 421. Figure 2 As shown, since the threads on both sides of the bidirectional threaded screw 414 are opposite, when it rotates, the two threaded cylinders 421 can move closer or further away synchronously, so that the shaft 422 set on it moves closer or further away synchronously, thereby limiting the columns of different sizes and preventing them from swaying left and right during the bending process.
[0028] The idler roller 52 includes an inner shaft 521, both ends of which are rotatably connected to corresponding support legs 51. An outer sleeve 522 is fitted over the inner shaft 521. The inner shaft 521 has several grooves 524 arranged in a circumferential array on its surface. The inner wall of the outer sleeve 522 is fixedly provided with several retaining ridges 523 corresponding to the grooves 524. Since the outer sleeve 522 is in direct contact with the column and bears relatively concentrated pressure for a long time, it can be regarded as a wear-prone part. Based on the above structure, the outer sleeve 522 can be quickly replaced, thereby extending the overall service life of the idler roller 52. In addition, the retaining ridges 523 and grooves 524 can increase the contact area between the outer sleeve 522 and the inner shaft 521, thereby improving the friction and ensuring the stability of the outer sleeve 522 installation.
[0029] The bending mechanism 3 includes a hydraulic cylinder 33 fixedly mounted on the bending frame 2, and also includes a lower die 31 and an upper die 32. The lower die 31 is fixedly mounted on the bending frame 2, and the upper die 32 is fixedly mounted on the shaft end of the hydraulic cylinder 33. At the same time, both the lower die 31 and the upper die 32 are provided with a centrally located positioning groove 35. During the bending process, the hydraulic cylinder 33 drives the upper die 32 to move downward. Through the pressing action between the upper die 32 and the lower die 31, the column is deformed in an oriented manner to complete the bending process. The positioning groove 35 can play a role in locking and positioning the circular column to prevent it from rolling between the upper die 32 and the lower die 31.
[0030] In addition, the bending mechanism 3 also includes two symmetrically arranged guide rods 34 that are slidably installed on the bending frame 2. Their bottom ends are fixedly connected to the upper mold 32. Through the guiding effect of the guide rods 34, the upper mold 32 can be made more stable during the up and down movement and is less prone to deviation.
[0031] The working principle and usage process of this utility model:
[0032] First, the installation of the uprights needs to be completed. Place one end of the upright on the lower mold 31 and make the other end overlap the outer sleeve 522, while the upright is arranged at an angle.
[0033] Next, the column needs to be limited. By turning the bidirectional threaded screw 414, the threaded cylinder 421 connected to it is driven to move closer, so that the shaft 422 connected to it moves closer, thereby limiting the column of different sizes and preventing it from swaying left and right during bending. Under this limiting measure, the anti-deviation shaft 42 slides in contact with the column, so it will hardly constrain the deformation of the column and there will be no wear of the column.
[0034] During the bending process, the hydraulic cylinder 33 drives the upper mold 32 to move downward. Through the pressing action between the upper mold 32 and the lower mold 31, the column is deformed in an oriented manner to complete the bending process. The positioning groove 35 can lock and position the circular column to prevent it from rolling between the upper mold 32 and the lower mold 31.
[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
