[0020] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 is the overall structural schematic diagram of the bending machine for sheet metal processing provided by the present utility model; Figure 2 is the schematic diagram of the support plate provided by the present utility model; Figure 3 is the schematic diagram of the fixing device provided by the present utility model; Figure 4 is the schematic diagram of the clamping assembly provided by the present utility model; Figure 5 is the exploded view of the clamping assembly provided by the present utility model.

[0022] In the specific implementation process, as Figures 1 - 5 shown, a bending machine for sheet metal processing includes a bending main body. A support assembly is provided at the bottom of the bending main body. The support assembly is provided with a placement groove. A folding frame 5 is provided inside the placement groove. Fixing devices for limiting the opposite sides of the folding frame 5 are provided on the opposite sides of the placement groove. Two mounting holes 11 corresponding to the positions of the two fixing devices are respectively provided on the opposite sides of the folding frame 5;

[0023] The fixing device includes a connecting plate 10 and two engaging components. The two engaging components extend movably into the two mounting holes 11 provided on the bending frame 5. The upper ends of the two engaging components are fixedly connected to the upper end of the connecting plate 10. The connecting plate 10 is used to synchronize the movement of the two engaging components. The engaging component includes a first movable rod 8, a second movable rod 13, a spring 9 and a reset block 12. One end of the first movable rod 8 is fixedly connected to one side inside the placement groove. The end of the first movable rod 8 away from the movable groove is in contact with one side of the bending frame 5. One end of the second movable rod 13 extends movably into the first movable rod 8. One end of the second movable rod 13 close to the first movable rod 8 is fixedly connected to one end of the spring 9. The end of the spring 9 away from the second movable rod 13 is fixedly connected to one side inside the first movable rod 8. A reset groove 14 is provided on the first movable rod 8. The reset block 12 is movably arranged inside the reset groove 14. The upper end of the reset block 12 is fixedly connected to the bottom end of the connecting plate 10. The end of the second movable rod 13 away from the first movable rod 8 extends into the mounting hole 11 provided on the bending frame 5;

[0024] During the specific use process, when it is necessary to replace the bending frame 5, first, the connecting plate 10 can be pulled towards the placement groove side. During this process, the movement of the connecting plate 10 can drive the two second movable rods 13 to move synchronously into the two first movable rods 8. At the same time, the synchronous movement of the two second movable rods 13 will synchronously compress the two springs 9 until the positions of the two second movable rods 13 are completely separated from the mounting holes 11, and then the bending frame 5 can be taken out from the inside of the placement groove to complete the disassembly of the bending frame 5. The edge of the side of the second movable rod 13 away from the first movable rod 8 is set to be arc-shaped;

[0025] When it is necessary to install the bending frame 5, since the edge of the side of the second movable column away from the first movable column is set to be arc-shaped, it is possible to directly squeeze the two second movable columns by the bottom of the bending frame 5, so that the second movable columns are directly squeezed into the first movable column. It is also possible to drive the second movable column into the first movable column through the movement of the connecting plate 10. When the position of the second movable column corresponds to the mounting hole 11, the second movable column is snapped into the mounting hole 11 by the elastic force of the spring 9 to complete the installation;

[0026] Among them, the end of the first movable rod 8 away from the movable groove is in contact with one side of the bending frame 5. The bending frame 5 can be further limited and fixed by the supporting force of the first movable column;

[0027] The bending body includes a cylinder 2, a mounting plate 1, a bending knife 3, and a sliding rod 4. There are multiple sliding rods 4. The bottom ends of the multiple sliding rods 4 are fixedly connected to the upper end of the support assembly. The upper ends of the multiple sliding rods 4 movably penetrate through the mounting plate 1. The upper ends of the multiple sliding rods 4 are also fixedly connected to a fixing plate 15. The cylinder 2 is fixedly installed on the fixing plate 15. The output end of the cylinder 2 is fixedly connected to the upper end of the mounting plate 1. The upper end of the bending knife 3 is fixedly connected to the bottom end of the mounting plate 1. The support assembly includes a support plate 6 and a support frame 7. The bottom ends of the multiple sliding rods 4 are all fixedly arranged on the upper end of the support plate 6. The support frame 7 is fixedly installed at the bottom of the support plate 6.

[0028] The working principle provided by the present utility model is as follows: During the use of the device, when it is necessary to replace the bending frame 5, first, the connecting plate 10 can be pulled towards one side of the placement groove. During this process, the movement of the connecting plate 10 can drive the two second movable rods 13 to move synchronously into the two first movable rods 8. At the same time, the synchronous movement of the two second movable rods 13 will synchronously compress the two springs 9 until the positions of the two second movable rods 13 are completely separated from the mounting holes 11, and then the bending frame 5 can be taken out from the inside of the placement groove to complete the disassembly of the bending frame 5. The edge on the side of the second movable column away from the first movable column is set to be arc-shaped;

[0029] When it is necessary to install the bending frame 5, since the edge on the side of the second movable column away from the first movable column is set to be arc-shaped, it is possible to directly squeeze the two second movable columns through the bottom of the bending frame 5, so that the second movable columns are directly squeezed into the first movable columns. It is also possible to drive the second movable columns into the first movable columns through the movement of the connecting plate 10. When the positions of the second movable columns correspond to the mounting holes 11, the second movable columns are snapped into the mounting holes 11 by the elastic force of the springs 9 to complete the installation.

[0030] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here too much.

[0031] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
