When encountering a positive corner during the mesh hanging process, workers need to use both hands to pinch the ends of the wire mesh and bend it to 90 degrees. This operation method has the problems of difficult bending, imprecise bending position, time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] Example 1: A wire mesh bending device, such as Figure 1 The vegetarian dish includes a first bending plate 1, a second bending plate 3, a first widening plate 12 and a second widening plate 13 extending in the front-to-back direction. The right end of the first bending plate 1 and the left end of the second bending plate 3 are hingedly connected. The relative rotation angle range of the first bending plate 1 and the second bending plate 3 is 0-180 degrees.
[0033] Specifically, in this embodiment, two first fixing rings 2 are fixedly provided on the right side of the first bent plate 1 and are spaced apart from each other. Two second fixing rings 4 are fixedly provided on the left side of the second bent plate 3 and are spaced apart from each other. The first fixing rings 2 and the second fixing rings 4 correspond to each other up and down, and the first fixing ring 2 is located between the two second fixing rings 4, and both the first fixing rings 2 and the second fixing rings 4 are located between the two first fixing rings 2.
[0034] A rotating shaft 5 is commonly passed through the first fixing ring 2 and the second fixing ring 4. The front and rear ends of the rotating shaft 5 extend to the front and rear outer sides of the first fixing ring 2. Through the cooperation of the rotating shaft 5, the first fixing ring 2 and the second fixing ring 4, the first fixing ring 2 and the second bending plate 3 are hingedly connected so as to be able to rotate.
[0035] In order to make the first fixing ring 2 and the second bending plate 3 have the ability to automatically reset after being turned over, Figure 1 and Figure 2 As shown, in this embodiment, torsion springs 7 are sleeved on both the front and rear ends of the rotating shaft 5 .
[0036] A third fixing ring 6 is fixed to the first fixing ring 2, with one end of a torsion spring 7 inserted into the third fixing ring 6. The other end of the torsion spring 7 is removably connected to a stopper assembly, which is removably mounted on the end of the rotating shaft 5. When the torsion spring 7 is in its initial position, the angle between the first bent plate 1 and the second bent plate 3 is 0 degrees.
[0037] Specifically, in this embodiment, threaded rod heads 501 are provided at both the front and rear ends of the rotating shaft 5. The limiting assembly includes an annular limiting plate 8, which is movably mounted on the threaded rod head 501. A fourth fixing ring 9 is fixedly mounted on the side of the limiting plate 8 facing the torsion spring 7, and the other end of the torsion spring 7 is inserted into the fourth fixing ring 9. An internally threaded sleeve 10 is fixedly mounted on the side of the limiting plate 8 facing away from the torsion spring 7. The internally threaded sleeve 10 is mounted on and threadedly connected to the threaded rod head 501. A handle 11 is fixedly mounted on the side wall of the internally threaded sleeve 10 and is perpendicular to the internally threaded sleeve 10.
[0038] like Figure 1 and Figure 3 As shown, the left side of the first bending plate 1, the right side of the second bending plate 3, the left side of the first widened plate 12, and the right side of the second widened plate 13 are all provided with anti-slip slots 15 that are transparent from top to bottom. The anti-slip slots 15 in this embodiment are dovetail slots. In other embodiments, the anti-slip slots 15 can also be replaced by T-slots or I-slots.
[0039] The right side of the first widening plate 12 and the left side of the second widening plate 13 are both equipped with insertion strips 14 that fit into anti-slip slots 15. Insertion strips 14 are movably inserted into the anti-slip slots 15 in the front-to-back direction, and the anti-slip slots 15 prevent the insertion strips 14 from slipping out in the left-to-right direction. The first widening plate 12 is used to widen the left-to-right width of the first bending plate 1, and the second widening plate 13 is used to widen the left-to-right width of the second bending plate 3 to accommodate the bending requirements of wire mesh sheets of varying widths.
[0040] like Figure 1 As shown, at least two sliding blocking rods are provided on the top of the first bending plate 1 and the first widening plate 12, which are spaced apart and can move up and down. Figure 4 As shown, the tops of the first bent plate 1 and the first widened plate 12 are each provided with two adjustment slots 16 spaced apart front to back. The sliding stopper comprises a slider 17 that slides back and forth within the adjustment slots 16. A stopper 19 is provided on the top of the slider 17, extending upward and protruding from the first bent plate 1. The stopper 19 is configured to be movably inserted into the mesh of the wire mesh to prevent the end of the wire mesh located on the first bent plate 1 from sliding when the wire mesh is bent.
[0041] In order to prevent the slider 17 from falling out of the adjustment slot 16, the left and right side walls of the adjustment slot 16 are provided with limiting slots extending in the front-to-back direction. Figure 5 As shown, the left and right sides of the slider 17 are fixed with limiting slide plates 18 that are slidably adapted to the adjustment slide groove 16, and the limiting slide plates 18 are inserted into the limiting slide groove for sliding back and forth.
[0042] The front and rear ends of the second bending plate 3 are fixed with a connecting plate 20 extending upward by fixing screws 21. A removable limiting rod 22 is movably inserted on the connecting plate 20. The limiting rod 22 extends in the front-to-back direction and is located directly above the second bending plate 3. Specifically, in order to avoid the need for workers to press the bending part of the wire mesh when bending the wire mesh, in this embodiment, Figure 1 and Figure 6 As shown, the limit rod 22 is a Z-shaped rod structure, and the limit rod 22 includes a first limit rod extending in the front-to-back direction, a third limit rod and a second limit rod extending in the left-to-right direction. The other end of the first limit rod is fixedly connected to the right end of the second limit rod, and the left end of the second limit rod is fixedly connected to one end of the third limit rod; the first limit rod is located directly above the second bending plate 3, and the third limit rod is located directly above the bending connection line between the first bending plate 1 and the second bending plate 3; a square hole that is transparent from front to back is opened on the connecting plate 20, and the first limit rod is a square rod structure that is adapted to the square hole, and the first limit rod is movably inserted into the square hole.
[0043] Working principle: When in use, according to the width of the steel wire mesh to be bent, adjust the number of the first widening plates 12 installed on the first bending plate 1 and the number of the second widening plates 13 installed on the second bending plate 3.
[0044] Then, lay the first bending plate 1 and the second bending plate 3 flat on the ground, pass the wire mesh from right to left between the limit rod 22 and the second bending plate 3, adjust the front and rear positions of the sliding block rod so that the block rod 19 of the sliding block rod is inserted into the mesh of the wire mesh to limit the movement of the wire mesh in the horizontal plane on the first bending plate 1.
[0045] Then, the worker rotates the second bending plate 3 upward. While the limit rod 22 limits the movement of the wire mesh away from the second bending plate 3, the wire mesh begins to bend from the contact point with the third limit rod under the limitation of the third limit rod of the limit rod 22. As the second bending plate 3 rotates upward to a vertical state, the wire mesh automatically forms an angle of 90 degrees.
[0046] Finally, pull out the two limiting rods 22 and remove the bent wire mesh.
[0047] Example 2: A wire mesh bending device, in which the tops of the first bending plate 1 and the first widening plate 12 are each provided with three adjustment slots 16 spaced apart from each other. Other structures are the same as those in Example 1.
[0048] Example 3: A wire mesh bending device. In this embodiment, the first fixing ring 2, second fixing ring 4, and rotating shaft 5 are no longer provided between the first bending plate 1 and the second bending plate 3. The first bending plate 1 and the second bending plate 3 are hingedly connected by a hinge. The rest of the structure is the same as that of Example 1.
[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
