Description
Technical Field
[0001] This utility model relates to the field of sheet metal processing technology, specifically a bending device for sheet metal processing. Background Technology
[0002] Sheet metal bending equipment is a specialized piece of equipment used in the sheet metal processing field for bending and forming sheet metal parts. This equipment applies pressure to flat sheet metal through the cooperation of a base device and a bending device, bending it into a preset angle or shape (such as right angles, rounded corners, etc.). Simultaneously, a conveyor structure ensures the orderly flow of the sheet metal. It is suitable for the batch bending production of various sheet metal components such as automotive parts, electrical appliance housings, and mechanical parts, providing a compliant forming structure for subsequent assembly and use of the sheet metal parts, ensuring the shape accuracy and functional requirements of the sheet metal products.
[0003] Traditional sheet metal bending devices have significant shortcomings in terms of automation and continuity of sheet metal feeding. Most devices rely on manual feeding, requiring operators to place sheet metal pieces one by one at the bending station. This is not only labor-intensive and inefficient, but also prone to errors in placement, leading to decreased bending accuracy. Furthermore, manual feeding requires close contact with the bending components, posing safety hazards. While some devices have basic feeding functions, they lack a stable reciprocating drive structure, causing sheet metal to easily shift or jam during transport, making precise alignment with the bending station impossible and requiring manual adjustment, thus interrupting the workflow. In addition, existing devices struggle to pre-arrange and continuously feed multiple sheet metal pieces. After each bending operation, the system must wait for the individual sheet metal to be fed before proceeding to the next operation, failing to form an efficient closed-loop operation of pre-arrangement, automatic feeding, and continuous bending. This severely restricts the batch production efficiency of sheet metal bending and fails to meet the sheet metal processing requirements for "automated feeding and continuous operation." Therefore, we propose a new sheet metal bending device. Utility Model Content
[0004] One of the technical problems this application aims to solve is that existing sheet metal processing equipment relies on manual feeding, which is not only labor-intensive and inefficient but also poses safety hazards, failing to meet the sheet metal processing requirements for "automated feeding and continuous operation". To solve the above-mentioned technical problems, this application provides a bending device for sheet metal processing, including a worktable. A fixing block is fixedly connected to the upper outer wall of the worktable. A limit groove is formed at the bottom end of the inner wall of the fixing block. An installation groove is formed at the bottom end of one side of the inner wall of the fixing block. A slider is movably connected to one side of the inner wall of the limit groove. A first slot is formed on one side of the outer wall of the upper end of the slider. A second slot is formed on one side of the outer wall of the upper end of the slider. A connector is fixedly connected to one side of the outer wall of the slider. A first return spring is movably connected to one side of the outer wall of the connector. A fixing member is fixedly connected to the upper outer wall of the fixing block. A plurality of cylinders are fixedly connected to one side of the outer wall of the upper end of the fixing member. A pressure block is connected to the lower end of the cylinder. A locking rod is fixedly connected to the lower end of the pressure block. A second return spring is movably connected to the upper outer wall of the locking rod. A sliding groove is formed on one side of the outer wall of the upper end of the fixing block.
[0005] In some embodiments, a first connecting block is fixedly connected to one side of the outer wall of the slider, a second connecting block is fixedly connected to the outer wall of the first connecting block away from the slider, and a third connecting block is fixedly connected to the outer wall of the second connecting block away from the first connecting block. The third connecting block has multiple placement slots.
[0006] In some embodiments, a base device is fixedly connected to the upper outer wall of the workbench, a bending device body is fixedly connected to one side of the upper outer wall of the workbench, a bending head is connected to the lower end of one side of the bending device body, a controller is fixedly connected to one side of the upper outer wall of the workbench, and a collection box is movably connected to one side of the upper outer wall of the workbench.
[0007] In some embodiments, a first reset spring provided on one side of the outer wall of the connector is fixedly connected to one side of the inner wall of the fixing block.
[0008] In some embodiments, the second reset spring is disposed between the outer wall of the upper end of the fixing block and the outer wall of the lower end of the pressure block.
[0009] In some embodiments, the locking rods are provided in multiple ways, and are respectively engaged with the first locking groove and the second locking groove opened on the slider, and the lower end of the locking rod is correspondingly connected to the mounting groove opened at the bottom of the inner wall of the fixing block.
[0010] In some embodiments, a groove formed on one side of the upper outer wall of the fixing block is correspondingly connected to one side of the outer wall of the second connecting block.
[0011] In some embodiments, the placement slot on the third connecting block is connected to both the base device and the bending head.
[0012] This utility model has at least the following beneficial effects: 1. In use, this utility model utilizes a reciprocating drive structure consisting of a fixed block, a slider, a cylinder, a locking rod, and a return spring to ensure the automation and continuity of sheet metal conveying. The starting cylinder drives the pressure block and locking rod downwards. The locking rod engages with the second locking groove of the slider via a protrusion, progressively driving the slider to offset along the limiting groove and compress the first return spring. When all the second locking grooves are connected to the locking rod and the slider cannot move, the cylinder drives the locking rod to engage with the first locking groove. The locking rod returns to its original position under the reaction force of the second return spring, and the slider, having lost its limiting position, returns to its original position under the action of the first return spring, forming a stable reciprocating motion. The slider drives the third connecting block to reciprocate synchronously through the first and second connecting blocks, ensuring precise alignment of the sheet metal in the groove on the third connecting block with the base device and bending device. Multiple sheet metals can be pre-arranged in the groove, eliminating the need for manual feeding and enabling a pre-arrangement, automatic conveying, and continuous bending process, significantly improving feeding efficiency and bending continuity.
[0013] 2. In use, this utility model ensures the precision of the bending operation and the smoothness of the finished product's release from the bent surface through a bending structure consisting of a placement groove, a base device, a bending device, and a bending head. The placement groove is only millimeters wide, ensuring precise positioning of the sheet metal and preventing offset during bending. The bending device drives the bending head downwards, pressing the sheet metal in the placement groove against the base device to complete the bending. The millimeter-wide placement groove allows the bent sheet metal to automatically detach from the groove without manual peeling, eliminating the problem of finished product jamming. At the same time, the sliding groove of the fixing block provides limiting support for the second connecting block, ensuring stable trajectory when the third connecting block drives the placement groove to move back and forth. This further ensures the docking accuracy between the sheet metal and the base device and bending head, avoiding bending dimensional errors caused by conveying offset and improving bending quality.
[0014] 3. In use, this utility model simplifies subsequent processes in terms of the convenience of finished product collection and overall operational efficiency. The auxiliary structure consisting of a collection box and a controller simplifies the process. Sheet metal that automatically detaches from the placement slot after bending can slide directly into the collection box on one side of the base device, eliminating the need for manual sorting and reducing manual intervention. The controller centrally controls the cylinder drive and bending device operation, achieving coordinated operation of feeding, bending, and detachment. Combined with the pre-arranged sheet metal design in the placement slot, this significantly shortens the single bending cycle and improves overall work efficiency. Furthermore, the step-by-step drive design of the slider ensures stable conveying speed, preventing damage from collisions during sheet metal movement and providing reliable assurance for continuous and stable bending. It is suitable for batch sheet metal bending production scenarios. Attached Figure Description

[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: Please refer to Figure 1-4 This utility model provides a technical solution: a bending device for sheet metal processing, including a worktable 1, a fixing block 2 fixedly connected to the upper outer wall of the worktable 1, a limiting groove 3 formed at the bottom of the inner wall of the fixing block 2, an installation groove 4 formed at the bottom of one side of the inner wall of the fixing block 2, a slider 5 movably connected to one side of the inner wall of the limiting groove 3, a first slot 6 formed at one side of the outer wall of the upper end of the slider 5, a second slot 7 formed at one side of the outer wall of the upper end of the slider 5, a connecting member 8 fixedly connected to one side of the outer wall of the slider 5, a first return spring 9 movably connected to one side of the outer wall of the connecting member 8, and the first return spring 9 on one side of the outer wall of the connecting member 8 being fixedly connected to one side of the inner wall of the fixing block 2. A fixing member 10 is fixedly connected to the upper outer wall of the fixing block 2. Multiple cylinders 11 are fixedly connected to the upper outer wall of the fixing member 10. A pressure block 12 is connected to the lower end of the cylinder 11. A locking rod 13 is fixedly connected to the lower end of the pressure block 12. Multiple locking rods 13 are provided and are respectively engaged with the first locking groove 6 and the second locking groove 7 opened on the slider 5. The lower end of the locking rod 13 is correspondingly connected to the mounting groove 4 opened at the bottom of the inner wall of the fixing block 2. A second return spring 14 is movably connected to the upper outer wall of the locking rod 13. The second return spring 14 is located between the upper outer wall of the fixing block 2 and the lower outer wall of the pressure block 12. A sliding groove 24 is opened on the upper outer wall of the fixing block 2.
[0019] In this embodiment, a workbench 1 is designed, and a fixing block 2 is fixedly connected to the upper outer wall of the workbench 1. A limiting groove 3 and a mounting groove 4 are respectively formed at the bottom of the inner wall of the fixing block 2. A slider 5 is movably connected to one side of the inner wall of the limiting groove 3, and a connector 8 is fixedly connected to the outer wall of one side of the slider 5. A first return spring 9 provided on the outer wall of one side of the connector 8 is fixedly connected to one side of the inner wall of the fixing block 2. A first slot 6 and multiple second slots 7 are formed on the upper outer wall of the slider 5. A fixing member 10 is fixedly connected to the upper outer wall. Multiple cylinders 11 are fixedly connected to the upper outer wall of the fixing member 10, and the lower ends of the multiple cylinders 11 extend to the lower side of the fixing member 10 and are fixedly connected to a pressure block 12. A locking rod 13 is fixedly connected to the lower end of each pressure block 12. The locking rod 13 can extend to the inner wall of the fixing block 2 and is respectively connected to the first locking groove 6 and the second locking groove 7 opened on the upper outer wall of the slider 5. A second return spring 1 is provided at the lower end of the pressure block 12 and on the upper outer wall of the fixing block 2. 4. The second return spring 14 is movably connected to one side of the outer wall of the locking rod 13. Therefore, when the cylinder 11 is activated, the cylinder 11 will drive the pressure block 12 and the locking rod 13 to shift downwards. At this time, the second return spring 14 will be squeezed, and the locking rod 13, due to its special feature (a protrusion on one side), can connect with the slot of the second locking groove 7, thereby causing the second locking groove 7 to shift on one side of the inner wall of the limiting groove 3. Multiple locking rods 13 are connected to the second locking groove 7, which can drive the slider 5 to shift on one side of the inner wall of the limiting groove 3 in stages. When slider 5 deflects, it will compress the first return spring 9. When all the second slots 7 are connected to the lever 13, slider 5 can no longer deflect. At this time, the cylinder 11 is activated to drive lever 13 to deflect from the first slot 6. This will cause lever 13 to leave the second slot 7, and lever 13 will be reset by the reaction force of the second return spring 14. Since slider 5 is not limited by lever 13, the first return spring 9 resets it by the reaction force. In this way, slider 5 can reciprocate.
[0020] Example 2: Please refer to Figure 1-2A first connecting block 15 is fixedly connected to one side of the outer wall of the slider 5. A second connecting block 16 is fixedly connected to the outer wall of the first connecting block 15 away from the slider 5. A groove 24 on one side of the upper end of the fixed block 2 is correspondingly connected to the outer wall of one side of the second connecting block 16. A third connecting block 17 is fixedly connected to the outer wall of the second connecting block 16 away from the first connecting block 15. Multiple placement slots 18 are provided on the third connecting block 17. A base device 19 is fixedly connected to the upper outer wall of the worktable 1. A bending device body 20 is fixedly connected to one side of the upper outer wall of the worktable 1. A bending head 21 is connected to the lower end of one side of the bending device body 20. The placement slots 18 on the third connecting block 17 are correspondingly connected to the base device 19 and the bending head 21. A controller 22 is fixedly connected to one side of the upper outer wall of the worktable 1. A collection box 23 is movably connected to one side of the upper outer wall of the worktable 1.
[0021] In this embodiment, a second connecting block 16 is fixedly connected to one side of the slider 5 via a first connecting block 15, and a third connecting block 17 is fixedly connected to the second connecting block 16. The third connecting block 17 has multiple placement slots 18, which can hold sheet metal. Therefore, when the slider 5 shifts within the limiting groove 3, the first and second connecting blocks 15 and 16 drive the third connecting block 17 to reciprocate. This allows the placement slots 18 on the third connecting block 17 to connect with the upper end of the base device 19 on the upper outer wall of the workbench 1, and simultaneously connect with the bending device body 20 and the lower end of the bending head 21 on one side of the upper outer wall of the workbench 1. Therefore, when the controller 22 on the upper side of the workbench 1 is activated, at this time… The controller 22 drives the bending device body 20 to operate and causes the bending head 21 to shift downward. At this time, the bending head 21 will drive the sheet metal placed in the placement groove 18 to connect with the base device 19, thereby completing the bending operation. The width of the placement groove 18 is only millimeters, so when the sheet metal is bent, it can automatically detach from the placement groove 18. A collection box 23 is provided on one side of the base device 19, so the bent sheet metal can automatically slide into the collection box 23, thereby improving work efficiency. Furthermore, through the design of the third connecting block 17 and the placement groove 18, the required sheet metal can be arranged in advance, greatly improving work efficiency. A sliding groove 24 is provided on the upper outer wall of the fixed block 2. The sliding groove 24 is limited to the second connecting block 16, which can stabilize the second connecting block 16 when it shifts.
