Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery rim bending, in particular to a bending device for processing agricultural machinery rims. Background Technique

[0002] An agricultural machinery rim is a structure installed on an agricultural machinery tire to support the stability of the tire and form a stable support structure for the movement of the agricultural machinery.

[0003] In the prior art, a plate is usually formed into an annular structure adapted to the tire by bending. Common bending methods are mostly rolling machines or bending machines, and the bending is achieved by the limiting and pressing of the pressing rollers.

[0004] However, when bending in the prior art, the end of the plate raw material is directly inserted into the gap between the pressing rollers. Therefore, the end often fails to extend circumferentially along the outer wall of the pressing roller due to reasons such as insufficient feeding speed or bending angle. And as the bending continues, when the end extends to the outside of the pressing roller, it forms a free end, which is prone to deformation and offset due to shaking or its own gravity, affecting the subsequent bending and extension of the plate. A common situation is that the end fails to accurately bend circumferentially along the main pressing roller due to offset, and the end offset thus abuts against the outer wall of the auxiliary roller. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bending device for processing agricultural machinery rims to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A bending device for processing agricultural machinery rims includes a bending device and an agricultural machinery rim. The bending device is composed of a main pressing roller and three groups of auxiliary rollers. The main pressing roller and the three groups of auxiliary rollers are installed on the rear side frame and the front side frame that are spaced apart front and back and distributed in parallel. A pair of extrusion rods are symmetrically installed on the front and rear sides of the main pressing roller. The agricultural machinery rim bends along the gap between the main pressing roller and the auxiliary rollers, and a pair of the extrusion rods are respectively clamped on the front and rear side walls of the end of the agricultural machinery rim.

[0008] Preferably, the rear side frame and the front side frame are fixedly connected by multiple groups of connecting rods distributed in a matrix, and a driving motor for driving the main pressing roller to rotate is arranged on the rear side frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0024] A bending device for agricultural machinery rim processing, including a bending device and an agricultural machinery rim. The bending device is composed of a main pressing roller 7 and three groups of auxiliary rollers 8. The main pressing roller 7 and the three groups of auxiliary rollers 8 are installed on the rear side frame 1 and the front side frame 2 which are spaced apart front and back and distributed in parallel. The rear side frame 1 and the front side frame 2 are fixedly connected by multiple groups of connecting rods 5 distributed in a matrix. A driving motor 3 for driving the main pressing roller 7 to rotate is provided on the rear side frame 1.

[0025] By setting the driving motor 3 to drive the main pressing roller 7 to rotate, the purpose of rotational bending is achieved.

[0026] A pair of extrusion rods 11 are symmetrically installed on the front and rear sides of the main pressing roller 7. The agricultural machinery rim is bent along the gap between the main pressing roller 7 and the auxiliary rollers 8, and the pair of extrusion rods 11 are respectively clamped on the front and rear side walls of the end of the agricultural machinery rim.

[0027] By setting the extrusion rods 11 symmetrically distributed front and back, when initially processing the plate of the agricultural machinery rim, the telescopic drive of the extrusion rods 11 is used to clamp the front and rear side walls of the processed plate. Then, as the processed plate is fed, bending along the main pressing roller 7 is achieved. Since its end is firmly clamped, its end is limited to only extend circumferentially along the main pressing roller 7, thus avoiding the offset extension or deformation of the end of the processed plate after it leaves the gap between the main pressing roller 7 and the auxiliary rollers 8, and improving the forming efficiency and quality.

[0028] Embodiment 2: On the basis of Embodiment 1, in order to further limit the movement position of the extrusion rod 11, a circular limiting rotating groove 6 is provided on the opposite end faces of the rear side frame 1 and the front side frame 2. The limiting rotating groove 6 is coaxially arranged with the main pressing roller 7. The end of the extrusion rod 11 is rotatably installed in the limiting rotating groove 6, and a connecting block 12 fixedly connected to the side wall of the main pressing roller 7 is provided on the side wall of the extrusion rod 11.

[0029] The fixed connection between the extrusion rod 11 and the main pressing roller 7 is realized by setting the connecting block 12, and the movement position of the end of the extrusion rod 11 is further limited by using the limiting rotating groove 6 to ensure its circumferential rotation along the main pressing roller 7.

[0030] Embodiment 3: On the basis of Embodiment 2, in order to further improve the convenience and precision of processing, a material guiding groove 4 is provided at the upper ends of the rear side frame 1 and the front side frame 2. The material guiding groove 4 is inclined and is directly opposite to the gap between the main pressing roller 7 and the auxiliary roller 8.

[0031] By providing the material guiding groove 4, the processed sheet is accurately inserted into the bending gap.

[0032] A plurality of groups of adjusting grooves 9 corresponding to the auxiliary roller 8 and distributed in a circumferential array are provided on the rear side frame 1. An expansion and contraction rod 10 is arranged in the adjusting groove 9. An end of the expansion and contraction rod 10 is provided with a lifting block 14. The auxiliary roller 8 is rotatably installed on the lifting block 14. A rotating motor 13 for driving the auxiliary roller 8 to rotate is arranged on the other side of the lifting block 14. A sliding groove 16 is arranged on the inner wall of the adjusting groove 9. A sliding block 15 which is slidably inserted in cooperation with the sliding groove 16 is arranged on the lifting block 14. A spring 17 is arranged at the upper end of the lifting block 14. The spring 17 is pressed between the upper inner wall of the adjusting groove 9 and the lifting block 14.

[0033] By providing the expansion and contraction rod 10 to adjust the position of the lifting block 14, the purpose of adjusting the gap width between the auxiliary roller 8 and the main pressing roller 7 is achieved, so as to ensure the pressing and bending of the sheet and adapt to the processing of sheets with different thicknesses. By providing the cooperation of the sliding block 15 and the sliding groove 16, the movement direction of the lifting block 14 is further limited, ensuring the stable and precise adjustment of the auxiliary roller 8. By providing the spring 17, an elastic pressing is formed.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
