[0002] Stainless steel plates refer to steel plates that are resistant to corrosion by weak media such as atmosphere, steam and water. They have high plasticity, toughness and mechanical strength. When using stainless steel plates, they sometimes need to be bent. When using a CNC bending machine to bend stainless steel plates, the stainless steel plates are placed on a load-bearing platform, and the hydraulic cylinder above drives the pressing parts to press down to bend the stainless steel plates. The two load-bearing platform surfaces rotate with the bending point of the stainless steel plates as the center to support the bottom of the stainless steel plates. However, when bending the stainless steel plates, it is not convenient to adjust and control the bending angle of the stainless steel plates by the downward movement of the pressing parts. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a CNC bending machine with adjustable bending angle of stainless steel plates, so as to solve the problem in the existing technology that the bending angle of the stainless steel plates cannot be adjusted and controlled by the downward movement distance of the pressing part.

[0004] In view of this, the utility model provides a CNC bending machine capable of adjusting the bending angle of a stainless steel plate, comprising a base, a mounting seat fixedly mounted on the bottom of one side of the base, and an adjustment component provided on the mounting seat;

[0005] The adjusting assembly includes two supporting plates, several clamping plates, several mounting grooves, a first rotating seat, a cylinder, a second rotating seat and a limiting rod. The two supporting plates are rotatably mounted on the top of the mounting seat, several clamping plates are fixedly mounted on the outer wall of the supporting plates, several mounting grooves are opened on both sides of the mounting seat, the first rotating seat is fixedly mounted on the bottom end of the mounting groove wall, the cylinder is rotatably mounted on one end of the first rotating seat, the limiting rod is slidably mounted on both sides of the mounting groove wall, the second rotating seat is fixedly mounted on the outer wall of the limiting rod, and the output end of the cylinder is rotatably mounted on one end corresponding to the second rotating seat.

[0006] Optionally, movable grooves are provided on both sides of the installation groove wall, and the limiting rod is slidably installed on the movable groove wall.

[0007] Optionally, mounting shafts are integrally formed on both sides of the supporting plate, and the supporting plate is rotatably mounted on the top of the mounting seat via the mounting shafts.

[0008] Optionally, one end of the clamping plate extends to the inside of the corresponding installation slot, and the clamping plate is located below the outer wall of the corresponding limiting rod.

[0009] Optionally, a hydraulic cylinder is fixedly mounted on the top of the base, a pressing member is fixedly mounted on the output end of the hydraulic cylinder, and the pressing member is located above between the two supporting plates.

[0013] 1. The utility model is a CNC bending machine with adjustable bending angle of stainless steel plate. By setting an adjustment component, when bending the steel plate, the supporting plate rotates with the bending degree of the steel plate, driving the clamping plate to move along the arc track. When the clamping plate hits the upper limit rod, it is blocked by the limit rod, so that the supporting plate cannot rotate. At this time, the bending of the steel plate is stopped, which can well control the bending angle of the steel plate and facilitate the adjustment of the bending angle of the steel plate.

[0014] 2. The utility model is a CNC bending machine with adjustable bending angle of stainless steel plate. A movable pad is arranged on the side of the bearing plate facing the steel plate. When bending the steel plate, the movable pad is in close contact with the surface of the steel plate. When the steel plate is pressed and bent, the movable pad can stick to the steel plate, reducing the wear caused by the displacement of the steel plate on the bearing plate, and can protect the bearing plate well.

[0022] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0023] The following describes in detail a CNC bending machine capable of adjusting the bending angle of a stainless steel plate according to an embodiment of the present invention with reference to the accompanying drawings.

[0024] Example 1

[0025] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a CNC bending machine with adjustable bending angle of stainless steel plate, including a base 1, a mounting base 2 is fixedly installed on the bottom of one side of the base 1, and an adjusting component is provided on the mounting base 2; the adjusting component includes two bearing plates 5, a plurality of clamping plates 6, a plurality of mounting grooves 3, a first rotating base 7, a cylinder 8, a second rotating base 9 and a limiting rod 11. The two bearing plates 5 are rotatably installed on the top of the mounting base 2, a plurality of clamping plates 6 are fixedly installed on the outer wall of the bearing plate 5, a plurality of mounting grooves 3 are opened on both sides of the mounting base 2, the first rotating base 7 is fixedly installed on the bottom end of the groove wall of the mounting groove 3, the cylinder 8 is rotatably installed at one end of the first rotating base 7, the limiting rod 11 is slidably installed on both sides of the groove wall of the mounting groove 3, the second rotating base 9 is fixedly installed on the outer wall of the limiting rod 11, and the output end of the cylinder 8 is rotatably installed on one end corresponding to the second rotating base 9.

[0026] It should be noted that, by setting an adjustment component, the cylinder 8 in the adjustment component can drive the limit rod 11 to move back and forth in the slide groove 12. The limit rod 11 is located above the card plate 6. When bending the steel plate, the supporting plate 5 rotates with the bending degree of the steel plate, driving the card plate 6 to move along the arc trajectory. When the card plate 6 hits the limit rod 11 above, it is blocked by the limit rod 11, so that the supporting plate 5 cannot rotate. At this time, the bending of the steel plate is stopped, which can well control the bending angle of the steel plate and facilitate the adjustment of the bending angle of the steel plate. By setting the limit rod 11, the card plate 6 can be blocked at the adjusted position, and the supporting plate 5 is supported at the bottom of the steel plate.

[0027] In this example, the movable groove 10 is arranged obliquely in the mounting groove 3 , and one end of the bottom of the movable groove 10 is close to the middle position of the mounting seat 2 .

[0028] In some embodiments, as Figure 2 As shown, movable grooves 10 are opened on both sides of the groove wall of the installation groove 3, and the limiting rod 11 is slidably installed on the groove wall of the movable groove 10. The two sides of the supporting plate 5 are integrally formed with the installation shaft 4. The supporting plate 5 is rotatably installed on the top of the mounting seat 2 through the installation shaft 4. One end of the clamping plate 6 extends to the inside of the corresponding installation groove 3, and the clamping plate 6 is located below the outer wall of the corresponding limiting rod 11.

[0029] It should be noted that the two bearing plates 5 are symmetrically arranged on the top of the mounting seat 2. When the steel plate is bent, the two bearing plates 5 rotate toward the bending direction of the steel plate, and the two bearing plates 5 rotate in opposite directions.

[0030] In some embodiments, as Figure 4 As shown, a hydraulic cylinder 16 is fixedly mounted on the top of the base 1 , and a pressing member 17 is fixedly mounted on the output end of the hydraulic cylinder 16 . The pressing member 17 is located above between the two supporting plates 5 .

[0031] It should be noted that the hydraulic cylinder 16 is activated to drive the pressing member 17 to move downward, pressing the steel plate to bend the steel plate.

[0032] Example 2

[0033] In some embodiments, as Figure 3 As shown, a plurality of slide grooves 12 are opened on one side of the supporting plate 5, and a slider 13 is slidably installed on the groove wall of the slide groove 12. A moving pad 14 is fixedly installed on one end of the slider 13, and springs 15 are fixedly installed on both sides of the slider 13. The other ends of the springs 15 are respectively fixedly installed on both sides of the groove wall of the slide groove 12.

[0034] It should be noted that by arranging a movable pad 14 on the side of the supporting plate 5 facing the steel plate, when the steel plate is bent, the movable pad 14 is close to the surface of the steel plate. When the steel plate is pressed and bent, the movable pad 14 can stick to the steel plate, reducing the wear caused by the displacement of the steel plate on the supporting plate 5, and can protect the supporting plate 5 well.

[0035] In this embodiment, the spring 15 is used to support the moving pad 14 to return to its original position.

[0036] The air cylinder 8 and the hydraulic cylinder 16 in the present invention are well-known components and will not be described in detail herein.

[0037] Working principle: When bending the steel plate, the cylinder 8 starts to drive the limit rod 11 to move in the slide groove 12, adjusts the position of the limit rod 11, and the hydraulic cylinder 16 starts to drive the pressing part 17 to move downward to press the steel plate. The two supporting plates 5 rotate in the bending direction of the steel plate. The rotation of the supporting plate 5 drives the card plate 6 to move along the arc trajectory. When the card plate 6 hits the upper limit rod 11, it is blocked by the limit rod 11, so that the supporting plate 5 cannot rotate, and the bending of the steel plate is completed.

[0038] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
