Description

Technical Field

[0001] This utility model belongs to the field of metal plate processing technology, and in particular relates to a bending device for processing thin metal plates. Background Technology

[0002] When bending thin metal sheets, small bending devices are usually sufficient to complete the bending process. However, the bending position of the sheet must be accurate. If the bending position deviates, the finished products of the same batch of sheets will have certain differences, affecting the quality of the finished products. At the same time, during bending, the sides of the sheet are affected by the shrinkage in the middle, and the sides will shrink as well. During the shrinkage process, it is easy to cause the edge to warp, which will also affect the quality of the finished products. Utility Model Content

[0024] In the following description, embodiments of the bending device for processing sheet metal according to the present invention will be described with reference to the accompanying drawings.

[0025] Figure 1-6 This invention illustrates a bending device for processing thin metal sheets according to an embodiment of the present invention. It includes a processing table 1 and a module 7. A base plate 2 is fixedly installed at one end of the top of the processing table 1. A support plate 4 is rotatably installed on one side of the top of the base plate 2. A rocker arm 3 is rotatably installed at one end of the top of the support plate 4. A limiting rod 5 is rotatably installed at the other end of the bottom of the support plate 4. Limiting plates 8 are fixedly installed on both sides of the top of the processing table 1. A stamping block 6 is slidably installed in the middle of the limiting plate 8. A limiting rod 5 is fixedly installed at one end of the stamping block 6. Connecting rods 9 are fixedly installed on both sides of the stamping block 6. A pressing rod 10 is fixedly installed on one side of the bottom of the connecting rod 9. Movable plates 11 are slidably installed on both sides of the processing table 1. A groove 15 is opened at one end of the movable plate 11. A crossbar 13 is slidably installed on one side of the movable plate 11. Two sets of movable plates 11 are connected by the crossbar 13. A placement plate 12 is fixedly installed on one side of each movable plate 11.

[0026] Specifically, the synchronous limiting structure limits the position of the board before bending. When the staff places the board, it can ensure that the bending position of the board is accurate enough and there will be no deviation. At the same time, during the bending process, the board is limited and shrinks at the same time to ensure that the limiting is accurate enough. The board will not fall off the limiting due to the change in length when shrinking, so that the limiting can follow at all times and ensure the stability of the limiting.

[0027] A limiting groove 17 is provided on one side inside the movable plate 11, and limiting rings 16 are fixedly installed at both ends of the crossbar 13. The limiting rings 16 cooperate with the limiting groove 17, and the limiting rings 16 and the limiting groove 17 are slidably connected.

[0028] Specifically, by setting the limiting groove 17 and the limiting ring 16, the movable plate 11 can be limited by the crossbar 13 during the movement, ensuring that the movement of the movable plate 11 will not deviate, while providing sufficient placement space for the crossbar 13 to ensure overall stability.

[0029] The top end of the extrusion rod 10 is curved, and the cross-section of the inclined groove 15 is inclined. The extrusion rod 10 and the inclined groove 15 are matched.

[0030] Specifically, the extrusion rod 10 with its curved surface can extrude more smoothly into the inclined groove 15 without jamming, while also reducing friction and making the movement more effortless.

[0031] A first spring 14 is sleeved on the outside of the crossbar 13, and the two sets of movable plates 11 are connected by the first spring 14.

[0032] Specifically, by setting the first spring 14, sufficient force can be provided for the reset of the placement plate 12, which facilitates the continuous operation of multiple batches of plates and allows subsequent plates to be placed normally.

[0033] The processing table 1 has slots on both sides of its top that mate with the placement plate 12, and the processing table 1 and the placement plate 12 are slidably connected. The bottom plate 2 has slots on both sides that mate with the movable plate 11.

[0034] Specifically, the slot opened at the top of the processing table 1 can limit the displacement of the placement plate 12, ensuring that the displacement of the placement plate 12 will not deviate, thereby ensuring more stable and accurate limiting of the plate.

[0035] Working principle: When using this utility model, the user can complete the positioning by placing the plate inside the placement plate 12 without precise placement. At this time, the user operates the rocker arm 3, which controls the displacement of the limiting rod 5 through the support plate 4. When the limiting rod 5 is displaced, it drives the stamping block 6 to move. At the same time, the second spring 18 is compressed, providing a restoring force for the subsequent reset of the limiting rod 5. At this time, the stamping block 6 moves to compress the plate. During the compression process, the middle of the plate bends, causing the two sides of the plate to shrink. When the stamping block 6 is displaced, it drives the connecting rod 9 and the extrusion rod 10 to move. At this time, the extrusion rod 10 is inserted into the inclined groove 15. Under the action of compression, the extrusion rod 10 compresses the movable plate 11 to move, and at the same time compresses the first spring 14. Meanwhile, the limiting rings 16 on both sides of the crossbar 13 slide inside the limiting groove 17 and are limited by the limiting groove 17. When the two sides of the plate shrink, the placement plate 12 moves accordingly, ensuring that the plate will not warp and preventing it from falling out of the limit of the placement plate 12.

[0036] Furthermore, through the synchronous limiting structure, the position of the board is limited before bending. When the worker places the board, it can be ensured that the bending position of the board is accurate enough and will not deviate. At the same time, during the bending process, the board is limited and simultaneously moves and retracts, ensuring that the limiting is accurate enough. The board will not fall out of the limiting due to changes in length during retraction, so that the limiting can always follow and ensure the stability of the limiting. By setting the limiting groove 17 and the limiting ring 16, the movable plate 11 is limited by the crossbar 13 during the movement, ensuring that the movement of the movable plate 11 will not deviate. At the same time, the crossbar 13 also serves as a limiting mechanism. 13 provides sufficient placement space to ensure overall stability. The extrusion rod 10 with its arc surface allows for smoother extrusion of the inclined groove 15 without jamming, while also reducing friction and making the movement more effortless. The first spring 14 provides sufficient force for the reset of the placement plate 12, facilitating the continuous operation of multiple batches of plates and ensuring proper placement of subsequent plates. The slot on the top of the processing table 1 limits the displacement of the placement plate 12, ensuring that the displacement of the placement plate 12 does not deviate, thus ensuring more stable and accurate positioning of the plates.

[0037] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
