Description

Technical Field

[0001] This utility model relates to the field of metal material bending, and specifically to a metal material bending device. Background Technology

[0002] Bending of metal materials is an important forming process in the field of metal processing. As the core equipment for realizing this process, the bending machine, with its precise pressure control and stable operating performance, can bend metal materials into various complex geometric shapes according to different processing needs. It is one of the indispensable key equipment in modern industrial production.

[0003] The reason why bending machines can bend and form metal materials lies in the synergistic effect of their upper and lower dies. The upper die (also often called a cutting tool) is the part that directly applies pressure to the metal material. In this process, the metal material is subjected to the pressure of the upper die and the supporting force of the lower die, and gradually undergoes plastic deformation within the groove of the lower die, eventually bending into a shape that matches the shape formed by the cooperation of the upper and lower dies.

[0004] In traditional bending machine designs, the cutting tool (i.e., the upper die) is typically a one-piece molded structure, and the tool is rigidly connected to the bending machine slide via an upper die holder and multiple bolts. While this fixing method ensures the stability of the tool during operation, it reveals significant drawbacks when the cutting edge wears and needs replacement. Operators must individually remove multiple bolts to loosen the upper die holder before the entire tool can be removed for replacement. This process is not only cumbersome and time-consuming, impacting production efficiency, but also, because the tool is a single piece, even if only the cutting edge is worn, the entire tool must be replaced, resulting in significant material waste and increased production costs. Therefore, it is essential to invent a metal bending device to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a metal material bending device. Through the cooperation of the dovetail groove and the dovetail slide, the cutter head and the cutter shank are designed to be separate. This allows only the cutter head to be replaced when it wears out, thus solving the problem of replacing the entire cutter when the cutting edge wears out, which leads to serious waste of cutter material. At the same time, the slider design allows the dovetail slide to be quickly limited after the cutter head and the cutter shank are installed, thereby ensuring the stability of the cutter head during use. This solves the problem of cutting tool replacement requiring the removal of multiple bolts, which is complicated, time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal material bending device, comprising: The tool holder is used to be installed on the slider of the bending machine. The bottom of the tool holder is provided with a dovetail groove, and the left and right sides of the tool holder are provided with sliding grooves. The left and right sides of the tool holder are provided with guide mechanisms. A dovetail slide, wherein the dovetail slide is inserted into the inner wall of the dovetail groove, and a cutting head is fixedly connected to the bottom of the dovetail slide; A limiting mechanism includes a limiting block slidably connected to the inner wall of a slide groove. A handle is slidably connected through the inner wall of the limiting block. A limiting post is fixedly connected to one end of the handle near the handle. A spring is fixedly connected between the side of the limiting post near the handle and the inner wall of the limiting block. A first locking hole and a second locking hole are sequentially opened from top to bottom on the inner wall of the slide groove.

[0007] Preferably, the guiding mechanism includes a guide block, which is fixedly connected to the outer wall of the handle, and the bottom of the guide block is in contact with the top of the blade.

[0008] Preferably, the guide block has a guide slope on the side near the dovetail groove, and the side of the guide slope near the handle is flush with the inner wall side of the dovetail groove.

[0009] Preferably, it further includes a lower die for cooperating with the cutter head to achieve bending of the metal material, the lower die being mounted on the worktable of the bending machine.

[0010] Preferably, when the limiting post is inserted into the second locking hole, the bottom of the limiting block can be limited inside the dovetail groove; when the limiting post is inserted into the first locking hole, the top of the limiting block can be fitted with the top of the sliding groove.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This utility model, through the design of a limiting mechanism, combined with a dovetail groove and a dovetail slide, allows for quick assembly and disassembly of the cutting head and the cutting shank. This means that when the cutting head wears out, only the cutting head needs to be replaced, without disassembling and replacing the cutting shank, thus reducing material waste and improving maintenance convenience. At the same time, the guide mechanism improves the accuracy of the dovetail slide and the dovetail groove connection, thereby enhancing the ease of cutting head installation.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 4 A metal material bending device is shown, including a tool holder 1, a dovetail slide 2 and a limiting mechanism 8; The tool holder 1 is used to install the slider of the bending machine. The bottom of the tool holder 1 is provided with a dovetail groove 5. The left and right sides of the tool holder 1 are provided with sliding grooves 7. The sliding grooves 7 can provide stable guidance for the limit block 81. The left and right sides of the tool holder 1 are provided with guide mechanisms 9. The bottom of the dovetail slide 2 is fixedly connected to the cutter head 6. The dovetail slide 2 is inserted into the inner wall of the dovetail groove 5. When the cutter head 6 is worn, it is only necessary to disassemble and replace the cutter head 6, without disassembling the cutter handle 1. The limiting mechanism 8 includes a limiting block 81, which is slidably connected to the inner wall of the slide groove 7. A handle 82 is slidably connected through the inner wall of the limiting block 81. A limiting post 83 is fixedly connected to one end of the handle 82 near the handle 1. By pulling or pushing the handle 82, the limiting post 83 can be inserted into the first locking hole 85 or the second locking hole 86, or pulled out from the first locking hole 85 or the second locking hole 86. A spring 84 is fixedly connected between the side of the limiting post 83 near the handle 82 and the inner wall of the limiting block 81. The elasticity of the spring 84 can make the limiting post 83 stably inserted into the first locking hole 85 or the second locking hole 86. The inner wall of the slide groove 7 is provided with the first locking hole 85 and the second locking hole 86 from top to bottom. It also includes a lower die 4 for cooperating with the cutter head 6 to achieve bending of metal materials. The lower die 4 is installed on the worktable of the bending machine. The lower die 4 is fixed on the worktable of the bending machine by a clamp. The metal material can be plastically deformed by the downward pressing of the cutter head 6 and the support of the lower die 4, thereby completing the bending work.

[0017] like Figure 2 - Figure 4 As shown, the guiding mechanism 9 includes a guide block 91, which is fixedly connected to the outer wall of the handle 1. The bottom of the guide block 91 is in contact with the top of the cutter head 6. The guide block 91 can limit the height of the cutter head 6, thereby aligning the top of the dovetail slide 2 with the top of the inner wall of the dovetail groove 5. A guide slope 92 is provided on the side of the guide block 91 near the dovetail groove 5. The side of the guide slope 92 near the handle 1 is flush with the inner wall side of the dovetail groove 5. The guide slopes 92 provided on the two sets of guide blocks 91 will guide the two sides of the dovetail slide 2, so that the two sides of the dovetail slide 2 can be aligned with the two sides of the inner wall of the dovetail groove 5 before entering the interior of the dovetail groove 5.

[0018] like Figure 1 , Figure 3 and Figure 4 As shown, when the limiting post 83 is inserted into the second locking hole 86, the bottom of the limiting block 81 can be limited inside the dovetail groove 5. By using the second locking hole 86 in conjunction with the limiting post 83, the limiting block 81 can be limited inside the slide groove 7. At this time, the limiting block 81 can be used to axially limit the left and right ends of the dovetail slide 2. When the limiting post 83 is inserted into the first locking hole 85, the top of the limiting block 81 can be attached to the top of the slide groove 7. By using the first locking hole 85 in conjunction with the limiting post 83, the limiting block 81 can be limited inside the slide groove 7. This allows the bottom of the limiting block 81 to disengage from the dovetail groove 5 and expose the opening of the dovetail groove 5, so that the dovetail slide 2 can be disassembled.

[0019] The working principle of this utility model is as follows: The lower die 4 is fixed to the worktable of the bending machine by a clamp. The cutter handle 1 is fixed to the slider of the bending machine by the upper die holder and bolts. The bending machine drives the slider to move up and down, which in turn drives the cutter handle 1 to move up and down. At the same time, with the cooperation of the dovetail groove 5 and the dovetail slide 2, the cutter handle 1 moves up and down, which drives the cutter head 6 to move up and down synchronously. The cutter head 6 moves down to compress the metal material. At the same time, with the support of the lower die 4, the metal material can be plastically deformed, thereby completing the bending work.

[0020] When the cutter head 6 is worn and needs to be smoothed, first pull the handle 82 to make it slide on the inner wall of the limiting block 81. The sliding of the handle 82 will cause the limiting post 83 to compress the spring 84 and move it out of the second locking hole 86. Then, push the limiting block 81 upward by the handle 82, so that the limiting block 81 slides upward on the inner wall of the slide groove 7. This will allow the bottom of the limiting block 81 to move upward out of the dovetail groove 5 until the top of the limiting block 81 is in contact with the top of the inner wall of the slide groove 7. Then, push the handle 82 to make it slide upward. The inner wall of the limiting block 81 slides, causing the limiting post 83 to insert into the first locking hole 85. At this time, the limiting block 81 is limited inside the slide groove 7 by using the first locking hole 85 in conjunction with the limiting post 83. At the same time, after the bottom of the limiting block 81 disengages from the dovetail groove 5, the opening of the dovetail groove 5 will be exposed. At this time, the cutter head 6 can be pushed, causing it to slide the dovetail slide 2 inside the dovetail groove 5. Thus, the dovetail slide 2 can slide out of the dovetail groove 5 from the opening of the dovetail groove 5, thereby allowing the cutter head 6 and... Separate the handle 1; then insert the dovetail slide 2 from the top of the replaced cutter head 6 into the opening of the dovetail groove 5. After the dovetail slide 2 is fully inserted, pull the handle 82 to slide it along the inner wall of the limiting block 81. The sliding of the handle 82 causes the limiting pin 83 to move out of the first locking hole 85. Then, push the limiting block 81 downwards with the handle 82, causing the limiting block 81 to slide downwards along the inner wall of the slide groove 7 until the bottom of the limiting block 81 enters the dovetail groove 5 and fits against the top of the cutter head 6. Push the handle 82 so that it slides on the inner wall of the limiting block 81 and drives the limiting post 83 to insert into the second locking hole 86. At this time, the limiting block 81 can be limited inside the slide groove 7 by using the second locking hole 86 in conjunction with the limiting post 83. At this time, the limiting block 81 can axially limit the left and right ends of the dovetail slide 2, and at the same time, the dovetail groove 5 can radially limit the dovetail slide 2, thereby fixing the dovetail slide 2 and then fixing the cutter head 6. Thus, the installation of the cutter head 6 is completed.

[0021] When it is necessary to insert the dovetail slide 2 on the top of the cutter head 6 into the opening of the dovetail groove 5, first, place the top of the cutter head 6 against the bottom of the guide block 91, and then align the dovetail slide 2 with the opening of the dovetail groove 5. At this time, the guide block 91 will limit the height of the cutter head 6, so that the top of the dovetail slide 2 can be aligned with the top of the inner wall of the dovetail groove 5. Then push the cutter head 6 to make it move the dovetail slide 2 closer to the guide block 91. At the same time, the guide slopes 92 opened on the two sets of guide blocks 91 will guide the two sides of the dovetail slide 2, so that the two sides of the dovetail slide 2 can be aligned with the two sides of the inner wall of the dovetail groove 5 before entering the interior of the dovetail groove 5. Thus, the dovetail slide 2 and the dovetail groove 5 can be quickly aligned during the installation of the cutter head 6, improving the convenience of installing the cutter head 6.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
