Description

Technical Field

[0001] This utility model belongs to the technical field of bending machine auxiliary equipment, specifically relating to an angle bending tooling structure. Background Technology

[0002] A bending machine is a widely used piece of equipment in the metal processing industry, capable of precisely bending metal materials. The bending machine applies force to metal sheets or bars using specific molds and pressure, causing them to bend at a predetermined angle and shape.

[0003] In existing technologies, when producing irregularly shaped parts with angles, the angled bending lines are usually first marked on the workpiece to be bent using laser. Then, the workpiece is placed into the V-groove of the bending machine at the angle of the bending line for bending. During this process, the user can only visually guide the workpiece into the V-groove by looking at the marked lines, making it difficult to ensure that the placement angles of multiple workpieces are completely consistent. This results in differences in bending angles between products, leading to inconsistent product quality and a low pass rate. Utility Model Content

[0004] In view of this, the present invention provides an angle bending fixture structure, the purpose of which is to improve the accuracy of the workpiece placement angle and maintain the consistency of the bending angle of each product.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An angle bending fixture structure, comprising:

[0007] A bending support, wherein a bending mold is provided on the top of the bending support;

[0008] A feeding plate is provided on one side of the bending support in the width direction. The top of the feeding plate and the top of the bending support are located on the same end face. The top of the feeding plate receives the workpiece to be bent. The length end of the workpiece to be bent faces the bending mold.

[0009] A positioning plate is rotatably disposed on the top of the feeding plate, and the positioning plate abuts against the workpiece to be bent and drives the workpiece to be bent to rotate, which is used to adjust the angle of the workpiece to be bent toward the bending mold.

[0010] As a preferred technical solution, it also includes a pin, which is located at the top of the feeding plate facing the bending support, and one end of the positioning plate along its length is sleeved on the pin, wherein the positioning plate rotates on the feeding plate with the pin as a fulcrum.

[0011] Furthermore, a scale is provided at the top end of the feeding plate away from the bending support, and the other end of the positioning plate is attached to the top of the scale. The end of the positioning plate that is attached to the scale has a scale hole for displaying the scale of the scale.

[0012] Furthermore, it also includes a chute, which is formed on the top of the feeding plate and is located between the pin and the dial, and the top of the chute is in contact with the bottom of the positioning plate.

[0013] Furthermore, the groove is an arc-shaped groove, and the curvature of the arc-shaped groove corresponds to the scale of the dial.

[0014] Furthermore, it also includes a fixing component, which includes a head cover and a threaded post. One end of the threaded post can movably pass through the slide and extend to the bottom of the feeding plate, while the other end of the threaded post passes through the positioning plate and is connected to the head cover. The bottom of the feeding plate is provided with a nut that is compatible with the threaded post.

[0015] Furthermore, it also includes a magnet, which is fixedly connected to one end of the feeding plate with a pin, and the feeding plate is connected to the bending support by the magnet. The bending mold at the top of the bending support is located below the external bending cutter, and the bending mold is a V-shaped groove.

[0016] Furthermore, the magnet and the feeding plate form an L-shaped structure, wherein the magnet is the short side of the L-shaped structure and the feeding plate is the long side of the L-shaped structure.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] By using the positioning plate and the dial, the workpiece to be bent can be placed at a fixed angle when placed in the V-groove, which makes it less likely for the bending angle to deviate between the metal plates, thereby improving the product qualification rate.

[0024] 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.

[0025] In existing technologies, the conventional operating procedure for producing angled irregularly shaped parts is to first use a laser to mark a bending line with a specific angle on the workpiece to be bent. Then, the workpiece is placed in the V-groove of the bending machine according to the angle of the bending line to perform the bending operation. However, this method has limitations because the user can only rely on visually observing the marked line to place the workpiece. Manual visual inspection makes it difficult to accurately control the placement angle of the workpiece, and the resulting deviations will lead to inconsistent bending angles during subsequent bending processes, resulting in significant fluctuations in product quality and a lack of stability.

[0026] Example 1

[0027] Therefore, in order to solve the above problems and improve the accuracy of workpiece placement angle, this utility model discloses an angle bending fixture structure, see reference. Figures 1-3 The device includes a bending support 3, a feeding plate 1, and a positioning plate 2. Specifically, the bending support 3 has a bending mold on its top. The feeding plate 1 is located on one side of the bending support 3 in the width direction, and the top of the feeding plate 1 is located on the same end face as the top of the bending support 3. The top of the feeding plate 1 receives the workpiece to be bent. One end of the workpiece to be bent in the length direction faces the bending mold. The positioning plate 2 is rotatably located on the top of the feeding plate 1, and the positioning plate 2 abuts against the workpiece to be bent and drives the workpiece to be bent to rotate, thereby adjusting the angle of the workpiece to be bent toward the bending mold.

[0028] In this embodiment, by rotating the positioning plate 2, the workpiece to be bent can be placed at a fixed angle when it is put into the bending mold (hereinafter referred to as V groove), so that the bending angle between the metal plates is less likely to deviate, thereby improving the product qualification rate.

[0029] In a specific embodiment, it also includes a pin 4 and a dial 8. The pin 4 is located at the top end of the feeding plate 1 facing the bending support 3. One end of the positioning plate 2 along its length is sleeved on the pin 4. The positioning plate 2 rotates on the feeding plate 1 with the pin 4 as a fulcrum. The top end of the feeding plate 1 away from the bending support 3 is provided with a dial 8. The other end of the positioning plate 2 is attached to the top of the dial 8. The end of the positioning plate 2 that is attached to the dial 8 has a scale hole 6, which is used to display the scale of the dial 8.

[0030] Thus, at the start of the bending process, the operator first places the workpiece to be bent on the feeding plate 1 and aligns it with the side of the positioning plate 2. Then, the operator simultaneously rotates the positioning plate 2 and the workpiece until the workpiece reaches a predetermined angle (based on the bending line marked on the workpiece). The workpiece is then pushed into the opening of the V-groove 3 at the current angle. Due to the positioning plate 2, the operator only needs to push the workpiece against the positioning plate 2 to ensure that the workpiece does not deviate in angle during movement. The operator can also record the exact value of the current angle of the positioning plate 2 using the scale 8. When bending subsequent products, the operator simply moves the positioning plate 2 to the same scale position and then places the next workpiece against the positioning plate 2, maintaining the same feeding angle as the previous workpiece. This ensures that subsequent products maintain the same bending angle, guaranteeing the consistency and accuracy of the product bending angle.

[0031] It should be noted that the opening of the V-groove is located below the external bending tool, and the external bending tool is controlled by a host computer. When the operator pushes the workpiece to be bent onto the opening of the V-groove, the host computer is turned on to control the bending tool to press down, thereby pressing the workpiece into the opening of the V-groove and completing the bending operation.

[0032] It is worth mentioning that, in order to improve the ease of docking between the feeding plate 1 and the bending support 3, this application also includes a magnet 10 for connecting the feeding plate 1 and the bending support 3. Specifically, the magnet 10 is fixedly connected to the end of the feeding plate 1 where the pin 4 is located. The feeding plate 1 and the bending support 3 are connected by the magnet 10. The magnet 10 attracts the feeding plate 1 and the bending support 3, which helps to reduce the tools required when connecting the feeding plate 1 and the bending support 3. It is expected to reduce the steps when docking the feeding plate 1 and the bending support 3, thereby improving the ease of docking between the feeding plate 1 and the bending support 3.

[0033] The magnet 10 and the feeding plate 1 form an L-shaped structure, wherein the magnet 10 is the short side of the L-shaped structure and the feeding plate 1 is the long side of the L-shaped structure. This arrangement can increase the contact area between the magnet 10 and the V-groove 3, which helps to improve the vertical support force on the long side of the feeding plate 1, so as to ensure that the connection between the feeding plate 1 and the V-groove 3 can be stable.

[0034] In addition, the positioning plate 2 has a scale hole 6 at the end that is in contact with the dial 8. The scale hole 6 is used to display the scale of the dial 8. This setting makes it less likely for the positioning plate 2 to obstruct the scale data on the dial 8. When the operator rotates the positioning plate 2, the scale data can be observed through the scale hole 6.

[0035] Furthermore, when the positioning plate 2 rotates on top of the feeding plate 1, the wear-resistant layer at the bottom of the positioning plate 2 helps to improve the friction between the positioning plate 2 and the surface of the feeding plate 1, thereby reducing the probability of tooling wear. The wear-resistant layer can be made of materials with high hardness and low coefficient of friction, such as ceramic coating or boron nitride coating.

[0036] Example 2

[0037] Based on Embodiment 1, in order to reduce the frequency of moving the positioning plate 2, this application also includes a fixing member 5 for fixing the positioning plate 2. Specifically, the fixing member 5 includes a head cover and a threaded post. One end of the threaded post can movably pass through the slide groove 7 and extend to the bottom of the feeding plate 1. The other end of the threaded post passes through the positioning plate 2 and is connected to the head cover. The bottom of the feeding plate 1 is provided with a nut 9 that is adapted to the threaded post.

[0038] In this embodiment, when the positioning plate 2 is rotated to a predetermined angle, the operator can use the fixing piece 5 to fix the positioning plate 2 in the current position, so that when subsequent products of the same batch are placed into the V groove 3, the position of the positioning plate 2 does not need to be adjusted again.

[0039] For example, in the initial state, the threaded post of the fixing member 5 is located in the groove 7 and is not tightened with the nut 9, at which time the positioning plate 2 can rotate freely. After the operator determines the predetermined angle according to the bending line marked on the workpiece to be bent and rotates the positioning plate 2 to the corresponding position, the head cover is tightened to make the threaded post and the nut 9 fit tightly, thereby fixing the positioning plate 2 at the current angle position. After completing the bending operation of a batch of products, if it is necessary to change to a different bending angle, simply loosen the head cover, release the restriction of the fixing member 5 on the positioning plate 2, and then rotate the positioning plate 2 to the new predetermined angle and re-fix it.

[0040] It should be noted that the slide groove 7 is a guide and limiting structure for the rotation of the positioning plate 2, and the slide groove 7 is a through groove. The slide groove 7 is opened on the top of the feeding plate 1, and the slide groove 7 is located between the pin 4 and the dial 8. The top of the slide groove 7 is in contact with the bottom of the positioning plate 2. In a specific embodiment, the cooperation between the slide groove 7 and the fixing member 5 helps to prevent the positioning plate 5 from falling off the feeding plate 1 during rotation.

[0041] Meanwhile, in order to prevent the rotation angle of the positioning plate 5 from exceeding the measurable range of the dial 8, the slide 7 is an arc-shaped groove, and the curvature of the arc-shaped groove corresponds to the scale of the dial 8, so that the angle changed by the positioning plate 5 when rotating will be within the testable range of the dial 8.

[0042] In summary, based on Embodiments 1 and 2, the working steps of this angle bending fixture structure are as follows:

[0043] First, the worker places the workpiece to be bent on the feeding plate 1, ensuring one side of the workpiece is flush with the side of the positioning plate 2. Next, following the bending line pre-marked on the workpiece using laser technology, the worker simultaneously rotates both the positioning plate 2 and the workpiece. During rotation, the wear-resistant layer at the bottom of the positioning plate 2 improves friction with the surface of the feeding plate 1, resulting in smoother rotation. Simultaneously, the worker can observe and control the rotation angle of the positioning plate 2 through the dial 8 and the graduated holes 6 on the positioning plate 2 until the workpiece reaches the predetermined angle.

[0044] Secondly, once the workpiece to be bent reaches the predetermined angle, the operator smoothly pushes it into the opening of the V-groove 3 at the current angle. Due to the presence of the positioning plate 2, the workpiece will move closely against the positioning plate 2 during the pushing process, effectively preventing angle deviation. If the products are from the same batch and have the same bending angle, the operator can use the fixing component 5 in Embodiment 2 to fix the positioning plate 2 in its current position, i.e., tighten the head cap to ensure a tight fit between the threaded post and the nut 9. This eliminates the need to readjust the angle of the positioning plate 2 in subsequent operations, reducing operation steps and time. If a different bending angle is required, after completing the current batch, loosen the head cap, release the fixing component 5 from the positioning plate 2, rotate the positioning plate 2 to the new predetermined angle, and re-fix it.

[0045] Finally, after pushing the workpiece to be bent onto the opening of V-groove 3, the operator turns on the host computer. The host computer, according to a preset program, controls the external bending tool to press down, pressing the workpiece into the opening of V-groove 3, completing the bending operation. Throughout the process, the feeding plate 1 and V-groove 3 are stably connected by magnet 10. The L-shaped structure design not only improves the ease of docking but also enhances the stability of the connection, providing reliable support for the entire bending process. After the bending operation is completed, the operator can perform a simple inspection and cleaning of the tooling, preparing for the next operation. This cycle continues, producing angled irregularly shaped parts with consistent bending angles and stable quality.
