Description

Technical Field

[0001] This application relates to the field of guardrail bending technology, and in particular to a positioning device for a guardrail bending machine. Background Technology

[0002] Bending guardrail panels is a process of shaping metal sheets into specific shapes using mechanical equipment to enhance the structural strength and aesthetics of the guardrail.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0004] First, when bending the sheet material, if there is a gap between the sheet material and the bending roller of the bending machine, the sheet material may move and cannot be kept in the designated position, resulting in the bending angle not meeting the standard.

[0005] Secondly, when the board is bent, the other end will rotate in the opposite direction, which not only increases the danger to the surrounding environment, but also reduces the accuracy of the bending angle of the board, thus affecting the normal use of the guardrail.

[0006] To address the aforementioned problems, the inventors have proposed a positioning device for a guardrail bending machine to solve these issues. Utility Model Content

[0007] In order to improve the problem that some existing devices may move when bending the sheet metal, the purpose of this utility model is to provide a positioning device for a guardrail bending machine.

[0008] To solve the above problems, this utility model provides the following solution: a positioning device for a guardrail bending machine, comprising a plate body, wherein a positioning mechanism and a fixing mechanism are fixedly installed on the top surface of the plate body in a mirror arrangement, the fixing mechanism being located on one side of the two positioning mechanisms, the positioning mechanism comprising a support shell, the support shell being fixedly installed on one side of the top surface of the plate body, a rotating roller being rotatably installed inside the support shell, a fixing plate being fixedly installed on one side of the support shell, a support plate being fixedly installed on one side of the fixing plate, a threaded rod being threadedly inserted into the middle of the support plate, and a top block being rotatably installed at one end of the threaded rod.

[0009] Preferably, the fixing mechanism includes a base plate, on the top surface of which two upright plates are fixedly installed. A lead screw is rotatably installed on the opposite side of each of the two upright plates. An extrusion block is threaded onto the outer surface of each of the two lead screws. The two extrusion blocks are slidably installed on the opposite side of the two upright plates. Two movable blocks are slidably installed on the top surface of the base plate. The opposite side of the two movable blocks is respectively in contact with the extrusion block on the same side.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a positioning mechanism, allows the sheet material to enter the bending assembly through the rotating roller. The top blocks on both sides can initially position the sheet material, thereby keeping it in a suitable position and improving the bending effect.

[0012] 2. This utility model, by setting a fixing mechanism, can fix the end of the board away from the bending point, thereby preventing the board from moving during bending and reducing the likelihood of board movement. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Example: Figure 1-3As shown, this utility model provides a positioning device for a guardrail bending machine, including a plate body 1, a support member for the plate body 1, and a positioning mechanism 3 and a fixing mechanism 2 that are mirror-distributed fixedly installed on the top surface of the plate body 1. The fixing mechanism 2 is located on one side of the two positioning mechanisms 3, and the top blocks 35 of the two positioning mechanisms 3 are distributed opposite to each other. The positioning mechanism 3 can position both sides of the plate.

[0020] The positioning mechanism 3 includes a support shell 31, which is used as a support component. The support shell 31 is fixedly installed on one side of the top surface of the plate 1. A rotating roller 37 is rotatably installed inside the support shell 31. The rotating roller 37 can make the plate pass through the two support shells 31 and enter the bending machine.

[0021] A fixing plate 32 is fixedly installed, which can fix the support plate 33. The fixing plate 32 is fixedly installed on the side of the support shell 31 near the vertical plate 25. The support plate 33 is fixedly installed on one side of the fixing plate 32. A threaded rod 34 is threadedly inserted in the middle of the support plate 33, so that the threaded rod 34 can rotate in the middle of the support plate 33.

[0022] A top block 35 is rotatably mounted on one end of the threaded rod 34. Slide rods 36 are fixedly mounted on both the upper and lower sides of the top block 35. The slide rods 36 are slidably mounted on the outer surface of the support plate 33, so that the top block 35 can be moved to position the plate.

[0023] The fixing mechanism 2 includes a base plate 29, which is used as a support. Two upright plates 25 are fixedly installed on the top surface of the base plate 29, and the two upright plates 25 can support the two pressing blocks 22.

[0024] Two vertical plates 25 are each rotatably mounted with lead screws 24 on their opposite sides. The lead screws 24 can drive the extrusion block 22 to descend. Handwheels 23 are fixedly mounted on the top surfaces of the two lead screws 24. Using the handwheels 23 makes it easier to rotate the lead screws 24.

[0025] Both lead screws 24 have a pressing block 22 threaded on their outer surfaces, so that the lead screw 24 drives the pressing block 22 to descend, thereby pressing the moving block 21. The two pressing blocks 22 are slidably installed on opposite sides of the two vertical plates 25, so that the pressing blocks 22 slide on one side of the vertical plate 25.

[0026] Two movable blocks 21 are slidably installed on the top surface of the base plate 29. The opposite sides of the two movable blocks 21 are respectively in contact with the pressing blocks 22 on the same side. The cross-sectional shapes of the two pressing blocks 22 and the two movable blocks 21 are all trapezoidal, and they are used together. When the pressing block 22 descends, it will press the movable block 21 through the inclined surface of the trapezoid, thereby causing the movable block 21 to move relative to each other.

[0027] The two upright plates 25 each have a groove 26 on their opposite sides. The two extrusion blocks 22 are slidably installed inside the two grooves 26, so that the extrusion blocks 22 slide inside the grooves 26. The top surface of the bottom plate 29 has a sliding groove 28. The bottom surfaces of the two moving blocks 21 are each fixedly installed with a slider 27 that cooperates with the sliding groove 28, so that the moving blocks 21 slide on the top surface of the bottom plate 29 through the slider 27.

[0028] Working principle: First, the device is installed at a suitable position on the bending machine table using plate 1. Then, the plate is positioned between the two positioning mechanisms 3. The plate is then pushed so that it can be moved more easily by rotating roller 37. When the plate needs to be positioned, a tool can be used to rotate threaded rod 34, which drives top block 35 to rotate. Threaded rod 34 rotates and moves inside support plate 33, thereby driving top block 35 to move. At the same time, top block 35 is limited by slide rod 36, so that top block 35 moves linearly until it is in contact with the side of the plate to position the plate.

[0029] Then, two fixing mechanisms 2 are used to fix the plate. The handwheel 23 is turned so that the handwheel 23 drives the lead screw 24 to rotate on one side of the upright plate 25. At the same time, the lead screw 24 drives the pressing block 22 to descend, so that the pressing block 22 slides inside the groove 26. Thus, its inclined side cooperates with the inclined side of the moving block 21, thereby pressing the moving block 21 to move. The moving block 21 slides on the top surface of the base plate 29 through the cooperation of the slider 27 and the slide groove 28. The two moving blocks 21 move relative to each other, which can press and fix the plate.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
