[0001] The utility model belongs to the technical field of bending machines, and particularly relates to a new type of steel plate bending machine. Background Art

[0002] A steel plate bending machine is an important sheet metal processing equipment, mainly used to press steel plates into various shaped parts according to process requirements. The steel plate bending machine is one of the indispensable important equipment in the sheet metal processing industry;

[0003] The working principle of the steel plate bending machine is mainly based on hydraulic transmission and mechanical synchronization system. During operation, first set the bending parameters and dimensions through the numerical control system, and then start the hydraulic system to make the oil cylinder work. The piston of the oil cylinder drives the slider to move up and down along the guide rail, and at the same time the mechanical synchronization system ensures the synchronous movement of the left and right sliders. When the slider descends to a certain position, pressure is applied to the steel plate to make it plastically deformed, so as to achieve bending.

[0004] When the existing bending machine is in use, in order to achieve bending shapes of different stamping shapes, the bending punch plate needs to be replaced, and the current installation structure makes it extremely inconvenient to replace the bending punch plate, thus affecting the processing efficiency of the bending machine. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a new type of steel plate bending machine, aiming to solve the problem that when the existing bending machine is in use, in order to achieve bending shapes of different stamping shapes, the bending punch plate needs to be replaced, and the current installation structure makes it extremely inconvenient to replace the bending punch plate, thus affecting the processing efficiency of the bending machine.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A new type of steel plate bending machine, comprising a bending machine main body, an installation bracket, a bending punch plate and a bending base. The installation bracket is installed on the inner wall of the bending machine main body, the side surface of the installation bracket is connected with the bending punch plate, and the surface of the bending machine main body is connected with the bending base;

[0007] One side of the installation bracket is provided with a pressing plate. The surface of the pressing plate is provided with a first guiding groove. The surface of the bending punch plate close to the first guiding groove is connected with a limiting rod. The surface of the pressing plate is provided with a round hole, and a fastening bolt penetrates through the round hole. The surface of the installation bracket close to the fastening bolt is provided with a first threaded hole. The side surface of the pressing plate is connected with a clamping block, and the surface of the bending punch plate close to the clamping block is provided with a limiting rod.

[0008] Preferably, the limiting rod and the pressing plate form a sliding connection through the first guiding groove.

[0009] Preferably, for a novel steel plate bending machine of the present utility model, the fastening bolt and the first threaded hole are in threaded connection, and the clamping block and the clamping groove form a clamping structure.

[0010] Preferably, for a novel steel plate bending machine of the present utility model, a limiting plate is provided on the side surface of the bending base. A bearing is fitted and installed on the surface of the limiting plate. A threaded rod passes through the inside of the bearing. A second threaded hole is opened on the surface of the bending base near the threaded rod. A guide rod is connected to the side surface of the limiting plate. A second guide groove is opened on the surface of the bending base near the guide rod.

[0011] Preferably, for a novel steel plate bending machine of the present utility model, the threaded rod and the bearing form a rotating structure, and the threaded rod and the second threaded hole form a rotating structure.

[0012] Preferably, for a novel steel plate bending machine of the present utility model, the guide rod is slidably connected to the bending base through the second guide groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, the bending punching plate drives the limiting rod to slide upward inside the first guide groove. When the bending punching plate drives the clamping groove to move to one side of the clamping block, the fastening bolt can be rotated reversely. The reverse rotation of the fastening bolt inside the first threaded hole can move in the direction close to the mounting bracket. In this way, the pressing plate can be pushed by the fastening bolt to move in the direction close to the mounting bracket. The pressing plate drives the clamping block to move into the clamping groove to fix the position of the bending punching plate, thereby realizing the rapid installation of the bending punching plate.

[0015] In the present utility model, while the threaded rod rotates inside the second threaded hole, it can drive the limiting plate to move horizontally through the bearing. In this way, the position of the limiting plate can be adjusted. During processing, the steel plate is clamped between the limiting plates, thereby avoiding the need for manual position fixing during bending and reducing the danger during bending.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides the following technical solutions: a new type of steel plate bending machine, including a bending machine main body 1, a mounting bracket 2, a bending punch plate 3 and a bending base 4. A mounting bracket 2 is installed on the inner wall of the bending machine main body 1, a bending punch plate 3 is connected to the side surface of the mounting bracket 2, and a bending base 4 is connected to the surface of the bending machine main body 1;

[0026] On one side of the mounting bracket 2, there is an extrusion plate 5. A first guide groove 6 is provided on the surface of the extrusion plate 5. A limiting rod 11 is connected to the surface of the bending punch plate 3 near the first guide groove 6. A round hole 7 is provided on the surface of the extrusion plate 5, and a fastening bolt 8 penetrates through the inside of the round hole 7. A first threaded hole 9 is provided on the surface of the mounting bracket 2 near the fastening bolt 8. A clamping block 10 is connected to the side surface of the extrusion plate 5, and a limiting rod 11 is provided on the surface of the bending punch plate 3 near the clamping block 10.

[0027] Preferably: The limiting rod 11 forms a sliding connection with the extrusion plate 5 through the first guide groove 6.

[0028] During specific use, the bending punch plate 3 drives the limiting rod 11 to slide upward inside the first guide groove 6, which can limit the movement direction of the bending punch plate 3.

[0029] Preferably, the fastening bolt 8 and the first threaded hole 9 are in threaded connection, and a clamping structure is formed between the clamping block 10 and the clamping groove 12.

[0030] During specific use, the reverse rotation of the fastening bolt 8 inside the first threaded hole 9 can drive the pressing plate 5 to move towards the mounting bracket 2, and the pressing plate 5 driving the clamping block 10 to move into the clamping groove 12 can fix the position of the bending punching plate 3.

[0031] Preferably, a limiting plate 13 is arranged on the side surface of the bending base 4, a bearing 14 is fitted and installed on the surface of the limiting plate 13, a threaded rod 15 is connected through the inside of the bearing 14, a second threaded hole 16 is formed in the surface of the bending base 4 close to the threaded rod 15, a guide rod 17 is connected to the side surface of the limiting plate 13, and a second guide groove 18 is formed in the surface of the bending base 4 close to the guide rod 17.

[0032] Preferably, a rotating structure is formed between the threaded rod 15 and the bearing 14, and a rotating structure is formed between the threaded rod 15 and the second threaded hole 16.

[0033] During specific use, when the threaded rod 15 rotates inside the second threaded hole 16, it can move horizontally at the same time, and the horizontal movement of the threaded rod 15 can drive the limiting plate 13 to move horizontally through the bearing 14.

[0034] Preferably, the guide rod 17 and the bending base 4 form a sliding connection through the second guide groove 18.

[0035] During specific use, the horizontal movement of the limiting plate 13 can drive the guide rod 17 to slide inside the second guide groove 18, so as to limit the movement direction of the limiting plate 13.

[0036] Working principle of implementation: When using this new type of steel plate bending machine and needing to replace the bending punching plate 3, rotate the fastening bolt 8. When the fastening bolt 8 rotates inside the first threaded hole 9, it can move downward at the same time. At this time, the pressing plate 5 can be pulled to move away from the mounting bracket 2. When the pressing plate 5 drives the clamping block 10 to move to the outside of the clamping groove 12, the bending punching plate 3 can be removed at this time. Then, the new bending punching plate 3 drives the limiting rod 11 to slide upward inside the first guide groove 6. When the bending punching plate 3 drives the clamping groove 12 to move to one side of the clamping block 10, the fastening bolt 8 can be rotated in the reverse direction. The reverse rotation of the fastening bolt 8 inside the first threaded hole 9 can move towards the mounting bracket 2. In this way, the pressing plate 5 can be squeezed by the fastening bolt 8 to move towards the mounting bracket 2, and the pressing plate 5 driving the clamping block 10 to move into the clamping groove 12 can fix the position of the bending punching plate 3, thereby realizing the installation of the bending punching plate 3;

[0037] While the threaded rod 15 rotates inside the second threaded hole 16, it can move laterally. The lateral movement of the threaded rod 15 can drive the limiting plate 13 to move laterally through the bearing 14. The lateral movement of the limiting plate 13 can drive the guide rod 17 to slide inside the second guide groove 18, so that the position of the limiting plate 13 can be adjusted. During processing, the steel plate is clamped between the limiting plates 13, and then the power mechanism drives the bending punch plate 3 to move downward through the mounting bracket 2, thereby bending the steel plate.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
