The main function is shearing. The punching and shearing machine can use the tool to perform intelligent and precise shearing of metal sheets and cut them into the required size and shape. Secondly, it has a punching function. The punching and shearing machine has a punching function and can use the punch to make holes of various shapes and sizes on the metal sheet. Therefore, it can realize the combined mechanical function and realize combined processing operations on the metal.

However, this technology still has the following problems when used.

[0004] During the punching and shearing process of the office desk countertop material, since the office desk countertop material has multiple surfaces and multiple corner positions, the punching and shearing process needs to be performed one by one, and the office desk countertop material after punching and shearing needs to be grooved one by one on the side, and the holes at the bending positions need to be punched one by one. This results in difficulty in achieving synchronous punching and shearing of multiple corner positions of the office desk countertop material when performing combined metal processing on the office desk countertop material, and difficulty in achieving synchronous vertical bending of multiple surfaces of the office desk countertop material, and difficulty in achieving synchronous horizontal bending of the grooves of multiple surfaces of the office desk countertop material, and difficulty in achieving synchronous side groove punching of multiple surfaces of the office desk countertop material, which results in a significant decrease in the efficiency of the combined metal processing of the punching and shearing machine, so a desk countertop material punching and shearing machine is needed.

[0039] In this embodiment, as shown in the attached Figure 8 - Attachment Fig.11 As shown, the multi-faceted synchronous combined punching assembly includes a punching pressure sensor 37 fixedly arranged at the output end of the punching electric cylinder 25. The bottom end of the punching pressure sensor 37 is fixedly connected to a linkage bar 38, and a groove outer ring 39 is welded to the bottom end of the linkage bar 38. The inner wall of the groove outer ring 39 is fixedly connected to multiple extrusion shafts 40.

[0040] The method of using the office desk panel punching and shearing machine of the present invention is as follows:

[0041] First, when the present invention is installed and used, first place the mounting plate 23 at the designated mounting position, punch holes at the mounting position according to the holes of the mounting plate 23, and then insert the expansion bolts into the holes of the mounting plate 23, so that the mounting plate 23 can be fixed and installed. After being fixed, the mounting plate 23 can provide support force for the socket frame 1.

At the same time, the support frame 19 supports multiple pillars 18, the pillars 18 support the limit blocks 17, the limit blocks 17 support and fix the punching scissors 16, and then the metal sheet 14 is inserted into the upper surface of the office desk 15, and the metal sheet 14 can be inserted into the gap surrounded by multiple limit blocks 17.

[0042] Secondly, when the present invention performs multi-faceted synchronous punching, shearing and bending combined processing, the punching and shearing electric cylinder 2 is started through the controller 24, and the punching and shearing electric cylinder 2 pushes the punching and shearing rod 3 to move downward, and the punching and shearing rod 3 drives the punching and shearing pressure sensor 4 to move downward, and the punching and shearing pressure sensor 4 causes the pressing plate 5 to move downward, and the pressing plate 5 drives the pressing ring 6 to move downward, and at the same time, the pressing ring 6 drives multiple corner punching and shearing shears 13 to move downward synchronously, and multiple corner punching and shearing shears 13 punch downward the edge corner positions of the metal sheet 14. At the same time, the fixed punching and shearing shears 16 and the corner punching and shearing shears 13 perform closed punching and shearing. When the pressure value sensed by the punching and shearing pressure sensor 4 is the same as the pressure value set by the controller 24, the punching and shearing electric cylinder 2 is closed through the controller 24. At the same time, the punching and shearing rod 3 drives the socket plate 7 to move downward, the socket plate 7 drives the linkage electric cylinder 8 to move downward, the linkage electric cylinder 8 drives the bending pressure sensor 9 to move downward synchronously, the bending pressure sensor 9 causes the pressing ring 10 to move downward, the pressing ring 10 drives multiple pressure columns 11 to move downward synchronously, so that the multiple pressure columns 11 respectively drive multiple bending plates 12 to move downward synchronously.

[0043] After the multiple corner punching shears 13 punch and shear the metal sheet 14 at the corner position, the linkage electric cylinder 8 is started through the controller 24. The linkage electric cylinder 8 pushes the bending pressure sensor 9 to move downward, the bending pressure sensor 9 drives the pressing ring 10 to move downward, the pressing ring 10 drives the multiple pressing columns 11 to move downward synchronously, and the multiple pressing columns 11 respectively drive the multiple bending plates 12 to move downward synchronously, the bending plates 12 press the upper surface of the metal sheet 14 downward, and the bending plates 12 drive the extended portion of the upper surface of the metal sheet 14 to bend downward by 90 degrees, so that the extended portion of the upper surface of the metal sheet 14 is attached to the side of the office desk 15, so that the extended portions of the upper surface of the metal sheet 14 are attached to the multiple side positions of the outer wall of the office desk 15 according to the specified bending force. At the same time, the sleeve ring 10 drives the sleeve frame plate 36 to move downward, the sleeve frame plate 36 drives the concave pressure strip 34 to move downward, the concave pressure strip 34 drives the lateral bending strip 35 to move downward synchronously, and the lateral bending strip 35 drives the two punching tools 44 to move downward synchronously. When the pressure value sensed by the bending pressure sensor 9 is the same as the pressure value set by the controller 24, the linkage electric cylinder 8 is closed by the controller 24.

[0044] Then, when the present invention performs multi-faceted lateral combined bending processing, the controller 24 is used to start the bending electric cylinder 26, and the bending electric cylinder 26 pushes the lateral pressure sensor 27 downward, and the lateral pressure sensor 27 drives the connecting strip 28 downward, and the connecting strip 28 can make the inner ring 29 of the groove move downward synchronously, and the inner ring 29 of the groove drives multiple pressing shafts 30 to move downward synchronously. At the same time, the pressing shaft 30 drives the top of the sleeve rod 31 to move downward, and the sleeve rod 31 drives the driving shaft 32 to move right, and the driving shaft 32 drives the hinge block 33 to move right, and the hinge block 33 drives the concave pressure strip 34 to move right, and the concave pressure strip 34 moves right along the inner wall of the sleeve frame plate 36. At the same time, the concave pressure strip 34 causes the lateral bending strip 35 to move right, and the lateral bending strip 35 moves right along the upper surface of the bending plate 12. In this way, the lateral bending strip 35 can drive the metal sheet 14 on the side of the desk 15 to bend in the side groove of the desk 15, and can synchronously perform lateral synchronous bending on the metal sheets 14 on multiple sides of the desk 15. When the pressure value sensed by the lateral pressure sensor 27 is the same as the pressure value set by the controller 24, the controller 24 closes the bending electric cylinder 26.

[0045] Finally, the present invention performs multi-faceted synchronous combined punching. The punching electric cylinder 25 is started by the controller 24. The punching electric cylinder 25 pushes the punching pressure sensor 37 downward. The punching pressure sensor 37 drives the linkage bar 38 downward. The linkage bar 38 makes the outer ring 39 of the groove move downward synchronously, and the outer ring 39 of the groove can drive multiple extrusion shafts 40 to move downward synchronously. The extrusion shaft 40 drives the top of the sleeve rod 41 to move downward, and the bottom of the sleeve rod 41 drives the push rod 42 to move right. The push rod 42 drives the concave block 43 to move right. The concave block 43 makes two punching tools 44 move right synchronously, and both punching tools 44 move right along the inner wall of the lateral bending strip 35. In this way, the two punching tools 44 can punch the metal sheet 14 on the side of the office desk 15, and the punching tools 44 inside the multiple lateral bending strips 35 can punch the metal sheets 14 on multiple surfaces of the outer wall of the office desk 15 synchronously. When the pressure value sensed by the punching pressure sensor 37 is the same as the pressure value set by the controller 24 , the punching electric cylinder 25 is closed by the controller 24 .
