Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically a new type of bending device for steel processing. Background Technology

[0002] Steel processing involves a series of treatments to alter the shape, size, and properties of steel to meet the needs of various industrial and construction fields. Bending is a typical process used to change the shape of steel. By applying pressure, the steel is bent at a certain angle around a specific axis or mold. In the construction industry, steel is often bent to make connectors for steel structure frames. In hardware processing, steel is also bent to manufacture various tool handles, etc.

[0003] However, existing technologies still have the following problems:

[0004] Most existing steel bending devices cannot guarantee high processing accuracy. They may rely on simple mold shapes for bending, resulting in inaccurate guidance of steel deformation and easy angular deviation. They also mostly lack buffer structures, leading to large impacts between the mold and the steel, which affects accuracy, especially when processing thin steel. Furthermore, some devices cannot meet the bending requirements of complex shapes, making it difficult to achieve the high precision and complex bending requirements of precision parts.

[0005] To address the aforementioned problems, the inventors have proposed a novel bending device for steel processing. Utility Model Content

[0006] To address the problem that bending devices cannot guarantee high processing accuracy, the purpose of this utility model is to provide a new type of bending device for steel processing.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A novel bending device for steel processing includes a table made of high-strength wear-resistant steel. The table surface is finely polished, resulting in extremely high flatness, providing a stable support base for the entire bending operation and effectively avoiding bending errors caused by table wobbling or unevenness during processing. Supports are fixedly mounted on both sides of the upper end of the table. Each support consists of two robust metal rods and a connecting crossbar. The metal rods are firmly connected to the table through welding, ensuring the stability of the support. The welds are inspected for defects to prevent loosening during long-term use. The connecting crossbar further enhances the connection strength between the two metal rods, enabling them to withstand greater pressure. The upper... A cylinder is fixedly installed at the middle of the end, and a pressure plate is fixedly installed at the output end of the cylinder. A bending plate is detachably installed at the lower end of the pressure plate. A lower template is detachably installed at the upper end of the table. A placement groove is opened at the upper end of the lower template. Mold grooves are opened on both sides of the lower inner wall of the placement groove. Movable grooves are opened on both sides of the lower end of the bending plate. A pressure block is rotatably installed between the inner walls of the two sides of the movable groove. The pressure block is used in conjunction with the mold groove. Two cylindrical grooves are opened at the lower end of the bending plate. A contact post is slidably installed on the lower side of the inner wall of the cylindrical groove. There is a very small gap between the inner diameter of the cylindrical groove and the outer diameter of the contact post to ensure that the contact post can slide smoothly up and down in the cylindrical groove. The inner wall of the cylindrical groove is chrome-plated to improve its wear resistance and smoothness. A spring is fixedly connected between the upper end of the contact post and the upper inner wall of the corresponding cylindrical groove.

[0008] Preferably, mounting plates are fixed at both ends of the bending plate, and the upper sides of the mounting plates are bolted to the pressure plate. Multiple bolt slots are provided on the upper sides of the pressure plate. A U-shaped frame is fixed at the upper end of the table, and the inner wall of the U-shaped frame is in contact with the outer surface of the lower template. A fixing block is fixed on one side of the upper end of the U-shaped frame, and the fixing block is bolted to the lower template. The design of the fixing block increases the reliability of the lower template fixing. The size and shape of the fixing block are designed according to the size of the lower template, and the bolt holes connecting the fixing block and the lower template are precisely aligned. Through bolt connection, the lower template can be stably fixed in the U-shaped frame and will not shift even under high-intensity bending operations. Four rectangular positioning posts are fixed at the lower end of the lower template, and four positioning slots for use with the positioning posts are provided at the upper end of the table.

Detailed Implementation

[0017] 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.

[0018] Example 1: As Figure 1-3As shown, this utility model provides a novel bending device for steel processing, including a table 1. A support 2 is fixedly mounted on both sides of the upper end of the table 1. A cylinder 21 is fixedly mounted in the middle of the upper end of the support 2. A pressure plate 22 is fixedly mounted at the output end of the cylinder 21. Limiting posts 23 are fixedly mounted on both sides of the upper end of the pressure plate 22, and the outer surfaces of the two limiting posts 23 are movably connected to the support 2. A bending plate 3 is detachably mounted on the lower end of the pressure plate 22. A lower template 4 is detachably mounted on the upper end of the table 1. A placement groove 41 is opened at the upper end of the lower template 4. The length of the bending plate 3 is greater than the distance between the inner walls of the placement groove 41. A mold groove 42 is opened on both sides of the lower inner wall of the placement groove 41. A movable groove 31 is opened on both sides of the lower end of the bending plate 3, and a pressure block 32 is rotatably mounted between the inner walls of the movable groove 31. The pressure block 32 cooperates with the mold groove 42. The steel to be bent is placed in the placement groove 41 of the lower template 4. The cylinder 21 is activated, and the cylinder 21 pushes the pressure plate 22 downward. Since the limiting posts 23 on both sides of the pressure plate 22 are movably connected to the bracket 2, this ensures that the pressure plate 22 moves stably in the vertical direction. The pressure plate 22 drives the bending plate 3 to move downward. When the bending plate 3 contacts the steel, it continues to press down. The pressure block 32 at the lower end of the bending plate 3 first contacts the steel. As the pressure increases, the pressure block 32 rotates in the movable groove 31 under the reaction force of the steel and gradually enters the mold groove 42 of the lower template 4. During this process, the pressure block 32 applies lateral pressure to the steel, causing the steel to begin bending along the direction of the mold groove 42. When the cylinder 21 pushes the pressure plate 22 to reach the predetermined stroke, one bending operation is completed. Then the cylinder 21 drives the pressure plate 22 to rise back, ready for the next bending.

[0019] Two cylindrical grooves 33 are provided at the lower end of the bending plate 3, and contact posts 34 are slidably provided on the lower side of the inner wall of the cylindrical grooves 33. A spring 35 is fixedly connected between the upper end of the contact post 34 and the upper inner wall of the corresponding cylindrical groove 33. At the same time, when the contact post 34 at the lower end of the bending plate 3 is subjected to the upward pressure of the steel, it will compress the spring 35 and slide upward. The spring 35 plays a buffering role, making the bending process more stable. It can also automatically adjust the position of the contact post 34 according to the thickness and hardness of the steel to ensure the bending accuracy and quality. Due to the design of the pressure block 32 that cooperates with the mold groove 42 on the lower template 4, as well as the buffered contact post 34 and spring 35 structure, the bending angle and shape of the steel can be precisely controlled. This precise cooperation can effectively reduce bending errors and meet the processing requirements with high steel bending accuracy, such as in the field of precision mechanical parts manufacturing.

[0020] Example 2: Figure 3As shown, mounting plates 5 are fixedly provided at both ends of the bending plate 3, and the upper sides of the mounting plates 5 are connected to the pressure plate 22 by bolts. Multiple bolt slots are provided on both sides of the upper end of the pressure plate 22. The bending plate 3 can be disassembled and installed. Specifically, the bending plate 3 is connected to the pressure plate 22 by bolts through the mounting plates 5 at both ends. The mounting plates 5 cooperate with the bolt slots on the pressure plate 22 to ensure that the bending plate 3 is stably installed under the pressure plate 22. At this time, the contact post 34 at the lower end of the bending plate 3 is in the initial position under the action of the spring 35, and the pressure block 32 can rotate freely in the movable groove 31.

[0021] A U-shaped frame 6 is fixedly installed at the upper end of the tabletop 1, and the inner wall of the U-shaped frame 6 is in contact with the outer surface of the lower template 4. A fixing block 61 is fixedly installed on one side of the upper end of the U-shaped frame 6, and the fixing block 61 is connected to the lower template 4 by bolts. Four positioning posts 62 distributed in a rectangle are fixedly installed at the lower end of the lower template 4, and four positioning slots 63 are opened at the upper end of the tabletop 1 to cooperate with the positioning posts 62. The lower template 4 can also be installed and removed. Specifically, the lower template 4 is inserted by aligning the four positioning posts 62 at its lower end with the positioning slots 63 on the tabletop 1 to achieve initial positioning. Then, the fixing block 61 on the U-shaped frame 6 is connected to the lower template 4 by bolts, so that the lower template 4 is firmly fixed in the appropriate position on the tabletop 1. The detachable design of the lower template 4 and the bending plate 3 facilitates quick replacement according to different steel specifications and bending requirements. Operators can easily replace the lower template 4 with different shaped mold grooves or the bending plate 3 suitable for specific bending tasks, reducing equipment adjustment time and improving processing efficiency.

[0022] Working principle: The steel to be bent is placed in the placement groove 41 of the lower template 4. The cylinder 21 is started, and the cylinder 21 pushes the pressure plate 22 downward. Since the limiting posts 23 on both sides of the pressure plate 22 are movably connected with the bracket 2, this ensures that the pressure plate 22 moves stably in the vertical direction. The pressure plate 22 drives the bending plate 3 to move downward. When the bending plate 3 contacts the steel, it continues to press down. The pressure block 32 at the lower end of the bending plate 3 first contacts the steel. As the pressure increases, the pressure block 32 rotates in the movable groove 31 under the reaction force of the steel and gradually enters the mold groove 42 of the lower template 4. During this process, the pressure block 32 applies lateral pressure to the steel, so that the steel begins to bend along the direction of the mold groove 42. When the cylinder 21 pushes the pressure plate 22 to the predetermined stroke, one bending operation is completed. Then the cylinder 21 drives the pressure plate 22 to rise back, ready for the next bending.

[0023] Meanwhile, when the contact post 34 at the lower end of the bending plate 3 is subjected to the upward pressure of the steel, it will compress the spring 35 and slide upward. The spring 35 plays a buffering role, making the bending process more stable. It can also automatically adjust the position of the contact post 34 according to the thickness and hardness of the steel to ensure the bending accuracy and quality. Due to the design of the pressure block 32 that cooperates with the mold groove 42 on the lower template 4, as well as the buffered contact post 34 and spring 35 structure, the bending angle and shape of the steel can be precisely controlled. This precise cooperation can effectively reduce bending errors and meet the processing requirements with high steel bending accuracy, such as in the field of precision mechanical parts manufacturing.

[0024] The bending plate 3 can be disassembled and installed. Specifically, the bending plate 3 is connected to the pressure plate 22 by bolts through the mounting plates 5 at both ends. The mounting plates 5 and the bolt grooves on the pressure plate 22 cooperate to ensure that the bending plate 3 is stably installed under the pressure plate 22. At this time, the contact post 34 at the lower end of the bending plate 3 is in the initial position under the action of the spring 35, and the pressure block 32 can rotate freely in the movable groove 31.

[0025] The lower template 4 can also be installed and disassembled. Specifically, the lower template 4 is inserted by aligning its four positioning posts 62 at its lower end with the positioning slots 63 on the table 1 to achieve initial positioning. Then, the fixing blocks 61 on the U-shaped frame 6 are connected to the lower template 4 with bolts, so that the lower template 4 is firmly fixed in the appropriate position on the table 1. The detachable design of the lower template 4 and the bending plate 3 facilitates quick replacement according to different steel specifications and bending requirements. Operators can easily replace the lower template 4 with different shaped mold slots or the bending plate 3 suitable for specific bending tasks, reducing equipment adjustment time and improving processing efficiency.

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.
