Description

Technical Field

[0001] The utility model relates to the technical field of copper sheet hemming machines, in particular to an anti-offset copper sheet hemming machine which is convenient for positioning. Background Technique

[0002] A copper sheet hemming machine is a mechanical device specifically used for processing copper sheets. It can bend copper sheets into the required shapes through mechanical force. A copper sheet hemming machine usually consists of a frame, a mold, and a control system. For example, in the patent with the publication number "CN216369701U" and the patent name "A hemming machine", during use, the hydraulic rod is started to push the mounting seat downward, thereby driving the connecting seat downward, and then driving the folding cutter towards the forming mold. By rotating the pull ring, the first threaded rod is driven to rotate, thereby driving the limiting block to move towards both sides and move into the moving groove, so that the limiting block disengages from the limiting groove on the connecting seat, thus facilitating the removal of the connecting seat from the mounting groove and making it more convenient to replace the folding cutter. When it is necessary to change the bending angle, the forming mold is placed in the fixed groove, and the assisting rod is rotated to drive the second threaded rod to rotate, so that the second threaded rod disengages from the pressing rod and the forming mold. The pressing rod is rotated to make the pressing rod away from the upper end of the forming mold, thereby removing the forming mold for easy replacement. The device is driven to move as a whole through the universal wheel 1. However, the above structure still has the following problems in the actual use process:

[0003] The above structure drives the folding cutter towards the forming mold through the hydraulic rod to complete the hemming effect. Since the forming mold is fixed, the hemming angle is also fixed. When it is necessary to bend the copper sheet to different angles, it is necessary to replace the forming mold by removing bolts, which is very cumbersome and labor-consuming, so the practicability is poor.

[0004] Therefore, we have proposed an anti-offset copper sheet hemming machine that is convenient for positioning, which can well solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-offset copper sheet hemming machine that is convenient for positioning, so as to solve the problem proposed in the above background technique that the forming mold in the current market is fixed, so the hemming angle is also fixed. When it is necessary to bend the copper sheet to different angles, it is necessary to replace the forming mold by removing bolts, which is very cumbersome and labor-consuming, so the practicability is poor.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An anti-offset copper sheet hemming machine that is convenient for positioning, including a bottom plate, a vertical plate is fixed to the rear side of the bottom plate, and the vertical plate is arranged in an "L" shape;

[0007] It further includes: an installation plate is fixed on the upper surface of the bottom plate, a worm is arranged on the strong side of the installation plate, the rear end of the worm penetrates through the front side installation plate and is connected to the front side surface bearing of the rear side installation plate, and a worm gear is meshed on the outer side surface of the worm;

[0008] A first bidirectional lead screw is fixed in the middle of the worm gear. At the same time, both ends of the first bidirectional lead screw are fixed to the side plates, and the lower ends of the side plates are fixedly connected to the upper surface of the bottom plate;

[0009] A moving block is threadedly connected to the outer side surface of the first bidirectional lead screw, the upper end surface of the moving block contacts the lower end of the connecting rod, the upper end surface of the connecting rod is fixed to the forming plate, and the forming plate is rotatably installed between the installation plates.

[0010] Preferably, there are two groups of the installation plates, and the highest point of the installation plates is higher than the highest point of the forming plate.

[0011] Preferably, there are two groups of the moving blocks, and the upper end surfaces of the moving blocks are arranged in an inclined structure facing each other.

[0012] Preferably, a servo motor is bolted to the right side of the bottom plate, the output end of the servo motor is fixed with a second bidirectional lead screw, the left end of the second bidirectional lead screw extends into the bottom plate, and the left end of the second bidirectional lead screw is connected to the bottom plate through a bearing.

[0013] Preferably, a moving rod is threadedly connected to the outer side surface of the second bidirectional lead screw, and there are two groups of the moving rods.

[0014] Preferably, a protective block is fixed to the inner side surface of the upper end of the moving rod, and the protective block is made of rubber material.

[0015] Preferably, a cylinder is fixed to the upper end surface of the vertical plate, there are two groups of the cylinders, and the output end of the cylinder penetrates through the vertical plate and is fixed to the folding cutter.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: This copper sheet folding machine that is convenient for positioning and prevents deviation not only achieves the effect of adjusting the folding angle, so that the angle can be adjusted without replacing the mold, the process is simple and the use is convenient. At the same time, due to the self-locking property between the worm and the worm gear, the stability during use is ensured. Moreover, the effect of limiting the copper sheet left and right is achieved, thereby preventing the position of the copper sheet from deviating before folding, which may lead to poor folding effect of the copper sheet, and ensuring the accuracy of copper sheet folding. The specific content is as follows:

[0017] (1) When the worm is rotated and drives the worm wheel to rotate together, the worm wheel can drive two moving blocks threadedly connected to its outside to approach each other through the first bidirectional lead screw. Then, the two moving blocks jack up the connecting rod, and the two forming plates rotate and approach each other towards the midpoint, thus achieving the effect of adjusting the hemming angle. Therefore, the angle can be adjusted without replacing the mold. The process is simple and convenient to use. At the same time, due to the self-locking property between the worm and the worm wheel, the stability during use is ensured.

[0018] Furthermore, due to the self-locking property between the worm and the worm wheel, the stability during use is ensured, and it will not move by itself due to external forces.

[0019] (2) By starting the servo motor, the servo motor drives the second bidirectional lead screw to rotate. Through the rotation of the second bidirectional lead screw, two moving rods are driven to approach each other, and then the moving rods drive the protective block to approach and contact the copper sheet, thus achieving the effect of limiting the copper sheet left and right, preventing the position of the copper sheet from shifting before hemming, which may lead to poor hemming effect of the copper sheet, and ensuring the accuracy of the copper sheet hemming.

[0020] Even further, the copper sheet is placed on the forming plate. Due to the structural setting that the top end of the mounting plate is higher than the forming plate, while blocking the copper sheet, the positioning effect is also achieved.

[0021] When it is necessary to increase the bending angle, only need to reverse the worm. Then, the worm drives the first bidirectional lead screw to reverse through the worm wheel. The first bidirectional lead screw drives two moving blocks to move away from each other. At this time, due to the inclined structure on the upper end surface of the moving block and the gravity of the connecting rod, the connecting rod drives the forming plate to rotate outward together, thus realizing the operation of expanding the angle.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 6 , the present utility model provides the following technical solutions:

[0031] Embodiment 1: To solve the problem that the forming die in the prior art is fixed, so the folding angle is also fixed. When it is necessary to bend the copper sheet to different angles, it is necessary to replace the forming die by removing the bolts, which is very cumbersome and labor-consuming, so the practicability is poor. Therefore, the following solution is disclosed. It includes a base plate 1, and a vertical plate 2 is fixed to the rear side of the base plate 1, and the vertical plate 2 is arranged in an "L" shape; it also includes: a mounting plate 5 is fixed to the upper surface of the base plate 1, and a worm 7 is arranged on the strong side of the mounting plate 5, and the rear end of the worm 7 penetrates through the front mounting plate 5 and is connected to the front side surface of the rear mounting plate 5 by a bearing, and a worm gear 8 is meshed on the outer side surface of the worm 7; a first bidirectional lead screw 9 is fixed in the middle of the worm gear 8, and at the same time, both ends of the first bidirectional lead screw 9 are fixed to the side plates 10, and at the same time, the lower ends of the side plates 10 are fixedly connected to the upper surface of the base plate 1; a moving block 11 is threadedly connected to the outer side surface of the first bidirectional lead screw 9, and the upper end surface of the moving block 11 contacts the lower end of the connecting rod 12, and the upper end surface of the connecting rod 12 is fixed to the forming plate 6, and the forming plate 6 is rotatably installed between the mounting plates 5. There are two groups of mounting plates 5, and the highest point of the mounting plate 5 is higher than the highest point of the forming plate 6;

[0032] When the angle of bending needs to be adjusted, only by rotating the worm 7, the worm 7 drives the worm wheel 8 to rotate together. Through the rotation of the worm wheel 8, the fixed first bidirectional lead screw 9 is driven to rotate together. Through the rotation of the first bidirectional lead screw 9, the two moving blocks 11 threadedly connected to the outside of the first bidirectional lead screw 9 are driven to approach each other. Then, the upper end surfaces of the two moving blocks 11 contact the connecting rod 12 and push the connecting rod 12 upward. Through the fixation between the upper end of the connecting rod 12 and the forming plate 6, and through the rotational connection formed between the forming plate 6 and the mounting plate 5, the two forming plates 6 rotate and approach each other towards the midpoint, and the angle between the two forming plates 6 changes, thus achieving the effect of adjusting the hem angle. Then, the angle can be adjusted without replacing the mold. The process is simple and convenient to use. At the same time, through the self-locking property between the worm 7 and the worm wheel 8, the stability during use is ensured;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment prevents the copper sheet from shifting before hemming, resulting in a poor hemming effect of the copper sheet, and ensures the accuracy of the copper sheet hemming. For details, refer to Figure 1 With Figure 6 The output end of the servo motor 13 is fixed with a second bidirectional lead screw 14. The left end of the second bidirectional lead screw 14 extends into the bottom plate 1, and the left end of the second bidirectional lead screw 14 is connected to the bottom plate 1 through a bearing. The outer side of the second bidirectional lead screw 14 is threadedly connected with two moving rods 15. The upper inner side of the moving rod 15 is fixed with a protective block 16, and the protective block 16 is made of rubber material. The upper end surface of the vertical plate 2 is fixed with two cylinders 3, and the output end of the cylinder 3 penetrates through the vertical plate 2 and is fixed to the folding cutter 4;

[0034] Subsequently, the copper sheet is placed on the forming plate 6. Through the structural setting that the top of the mounting plate 5 is higher than the forming plate 6, while blocking the copper sheet, the positioning effect is also achieved. At the same time, by starting the servo motor 13, the servo motor 13 drives the second bidirectional lead screw 14 to rotate. Through the rotation of the second bidirectional lead screw 14, the two moving rods 15 are driven to approach each other. Then, the moving rod 15 drives the protective block 16 to approach and contact the copper sheet, thus achieving the effect of limiting the copper sheet left and right, preventing the copper sheet from shifting before hemming, resulting in a poor hemming effect of the copper sheet, and ensuring the accuracy of the copper sheet hemming;

[0035] Embodiment 3: Different from Embodiment 1, this embodiment facilitates the operation of expanding the angle. For details, refer to Figure 3 With Figure 6 , there are two moving blocks 11, and the upper end surfaces of the moving blocks 11 are arranged in an inclined structure. The servo motor 13 is bolted to the right side of the bottom plate 1;

[0036] Meanwhile, by starting the cylinder 3, the two groups of cylinders 3 drive the folding bending knife 4 to move downward, so that the folding bending knife 4 is inserted into the forming plate 6 and the copper sheet is folded. After the folding is completed, the copper sheet can be taken out and a new copper sheet can be put in to work again. Moreover, when it is necessary to increase the bending angle, only the worm 7 needs to be reversed, so that the worm 7 drives the first bidirectional lead screw 9 to reverse through the worm wheel 8, so that the first bidirectional lead screw 9 drives the two moving blocks 11 to move away from each other. At this time, due to the inclined structure on the upper end surface of the moving block 11 and the gravity of the connecting rod 12, the connecting rod 12 drives the forming plate 6 to rotate outward together, thus realizing the operation of expanding the angle.
