[0025] The punching stabilizing mechanism 2 includes a fixed frame plate 21, a push-down platform 23 and two groups of stabilizing blocks 26. The upper end of the fixed frame plate 21 is fixedly installed with a cylinder 22, and the lower end of the push-down platform 23 is fixedly installed with multiple groups of supporting springs 24. The inner sliding installation of multiple groups of vertical rods 25 of the push-down platform 23 is carried out. The upper ends of the two groups of stabilizing blocks 26 are penetrated by two groups of punching heads 27 that are slidably installed. The protruding end of the cylinder 22 penetrates the upper end of the fixed frame plate 21 and is fixed to the upper end of the push-down platform 23. The lower ends of the multiple groups of supporting springs 24 are respectively fixed to the upper ends of the two groups of stabilizing blocks 26, and the lower ends of the multiple groups of vertical rods 25 are respectively located inside the multiple groups of supporting springs 24, and the lower ends of the multiple groups of vertical rods 25 are respectively fixed to the upper ends of the two groups of stabilizing blocks 26. The upper ends of the four groups of punching heads 27 are fixed to the lower end of the push-down platform 23, and the upper end of the fixed frame plate 21 is penetrated by four groups of guide cylinders 28. The interiors of the four groups of guide cylinders 28 are slidably installed with stabilizing columns 29. The lower end of the fixed frame plate 21 is fixed to the upper end of the support frame 1, and the lower end of the push-down platform 23 is fixedly installed with four groups of limiting columns 210. The lower ends of the four groups of stabilizing columns 29 are fixed to the upper end of the push-down platform 23.

A square hole 13 is penetrated through the upper end of the support frame 1, and the square hole 13 is located directly above the collection box 11 and directly below the processing table 12.
[0026] The following is a detailed description of the specific settings and functions of this embodiment. By starting the cylinder 22, the protruding end of the cylinder 22 drives multiple groups of support springs 24, multiple groups of vertical rods 25 and four groups of punching heads 27 downward together through the push-down platform 23, and the multiple groups of support springs 24 drive the two groups of stabilizing blocks 26 downward together. When the two groups of stabilizing blocks 26 contact the inner bottom end of the sheet metal, the cylinder 22 is continued to be controlled to operate, and the protruding end of the cylinder 22 moves downward through the push-down platform 23, and the push-down platform 23 drives the four groups of punching heads 27 to pass through the two groups of stabilizing blocks 26 and continue to move downward until the four groups of punching heads 27 are inserted into the pre-pressed positions inside the processing table 12. The groove force is retained, and during this period, the push-down platform 23 will also drive the multiple groups of supporting springs 24 and the multiple groups of vertical rods 25 to move, so that the multiple groups of supporting springs 24 are squeezed between the push-down platform 23 and the two groups of stabilizing blocks 26, and the upper parts of the multiple groups of vertical rods 25 slide inside the push-down platform 23, thereby punching the sheet metal. During this period, the two groups of stabilizing blocks 26 can fix the sheet metal, thereby preventing local deformation of the sheet metal when punching the sheet metal, and will not affect the overall flatness of the sheet metal, preventing the sheet metal from warping, and no subsequent additional leveling process is required to restore the flatness of the sheet metal, thereby reducing production costs and processing time;
[0027] When the push-down platform 23 moves downward, the push-down platform 23 will drive the four groups of stabilizing columns 29 to slide inside the four groups of guide cylinders 28, thereby increasing the stability of the push-down platform 23 when it is pressed downward. At the same time, the push-down platform 23 will also drive the four groups of limiting columns 210 to move downward until the four groups of limiting columns 210 are all inserted into the interior of the processing table 12, thereby being able to limit the two sides of the sheet metal and prevent it from shifting sideways when punching the sheet metal.
[0028] When punching the sheet metal, the waste generated will fall into the interior of the collection box 11 through the square hole 13, so that the waste can be collected in a centralized manner, which is convenient for subsequent unified treatment of the waste.
[0029] Example 2: Figure 1 、 Figure 3 and Figure 4 As shown, the positioning mechanism 3 includes a fixed convex plate 31, a telescopic rod 32 is installed through one end of the fixed convex plate 31, a connecting head 33 is fixedly installed on the protruding end of the telescopic rod 32, a fixing column 35 is welded to the upper end of the fixed convex plate 31, a special-shaped plate 34 is rotatably installed on the outer wall of the fixing column 35, a positioning plate 36 is welded to the outer wall of the special-shaped plate 34, a part of the special-shaped plate 34 is rotatably installed inside the connecting head 33, and the lower end of the fixed convex plate 31 is fixed to the upper end of the support frame seat 1.
[0030] The effect achieved by the entire embodiment is that by activating the telescopic rod 32, the extended end of the telescopic rod 32 drives the special-shaped plate 34 to move through the connecting head 33, and the special-shaped plate 34 rotates on the outer wall of the fixed column 35. At the same time, the special-shaped plate 34 drives the positioning plate 36 to move to the upper end of the processing table 12, thereby positioning the sheet metal, so that the sheet metal can be placed in a suitable position, thereby improving the accuracy of sheet metal punching;
[0031] When the connecting head 33 pushes the special-shaped plate 34 to move, a portion of the special-shaped plate 34 will also rotate inside the connecting head 33, so that the special-shaped plate 34 can drive the positioning plate 36 to move to a specified position.
[0032] The method of using and working principle of this device: First, start the telescopic rod 32, and the protruding end of the telescopic rod 32 drives the special-shaped plate 34 to move through the connecting head 33, and the special-shaped plate 34 will rotate on the outer wall of the fixed column 35. At the same time, the special-shaped plate 34 drives the positioning plate 36 to move, so that it moves to the upper end of the processing table 12, and then the sheet metal can be positioned, and the sheet metal can be placed in a suitable position. Then, the sheet metal is placed on the upper end of the processing table 12, and one end of the sheet metal must contact one end of the positioning plate 36. After that, the positioning mechanism 3 is manipulated to move the positioning plate 36 from the upper end of the processing table 12. Finally, start the cylinder 22, and the protruding end of the cylinder 22 drives multiple groups of support springs 24, multiple groups of vertical rods 25 and four groups of punching heads 27 downward together through the push-down table 23, and the multiple groups of support springs 24 drive the two The two groups of stabilizing blocks 26 move downward together. When the two groups of stabilizing blocks 26 contact the inner bottom end of the sheet metal, the cylinder 22 continues to be controlled to operate. The protruding end of the cylinder 22 moves downward through the push-down platform 23. The push-down platform 23 drives the four groups of punching heads 27 to pass through the two groups of stabilizing blocks 26 and continue to move downward until the four groups of punching heads 27 are inserted into the reserved grooves inside the processing table 12. During this period, the push-down platform 23 will also drive multiple groups of supporting springs 24 and multiple groups of vertical rods 25 to move, so that the multiple groups of supporting springs 24 are squeezed between the push-down platform 23 and the two groups of stabilizing blocks 26, and the upper parts of the multiple groups of vertical rods 25 slide inside the push-down platform 23, so that the sheet metal can be punched. During this period, the two groups of stabilizing blocks 26 can fix the sheet metal, and the waste generated by punching the sheet metal will fall into the inside of the collection box 11 through the square hole 13.
