DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-7 The utility model provides a technical solution: a punching device for double-joined C-shaped steel that is easy to position, comprising: a machine tool 1, a column 2, a tool holder 3, an air pump 4, a filter box 5, a telescopic tube 6, a dust removal port 7, a connecting block 8, an adjustment plate 9, an electric telescopic rod 10, a limit block 11, a reset spring 12, a dust box 13, a tool 14, a mounting rod 15, a spring 16, a mounting block 17, a fixing rod 18, a support spring 19 and a positioning frame 20;

[0030] First, as attached Figure 1 As shown in the figure, the double C-shaped steel to be punched is installed above the machine tool 1, the tool holder 3 slides on the outside of the column 2, the height of the tool holder 3 is adjusted, and the tool 14 installed below the tool holder 3 punches the double C-shaped steel, as shown in the attached figure. Figure 7As shown in , when the tool holder 3 descends, the positioning frame 20 first contacts the double-piece C-shaped steel to limit the double-piece C-shaped steel to prevent the double-piece C-shaped steel from shaking, and the tool holder 3 continues to descend to punch holes. The support spring 19 wound around the outer side of the lower end of the fixed rod 18 ensures the stability of the positioning frame 20. The fixed rod 18 fixed below the tool holder 3 slides in the positioning frame 20 connected to the slot therewith, stretching the support spring 19. When the punching is completed, the tool holder 3 is lifted, and the positioning frame 20 is driven to lift;

[0031] As attached Figure 2 and attached Figure 3 As shown in , when punching, the vacuum pump 4 is turned on, and the vacuum pump 4 removes dust through the telescopic tube 6 and the dust removal port 7. The dust removal port 7 sucks the debris and dust generated during punching into the filter box 5 through the telescopic tube 6. The filter box 5 is provided with a filter plate to block the dust and debris, which is convenient for centralized cleaning. When dust removal, the electric telescopic rod 10 is turned on, and the electric telescopic rod 10 pushes the adjustment plate 9 installed at its output end to slide left and right. The adjustment plate 9 drives the connecting block 8 engaged and connected below to rotate, and the connecting block 8 drives the dust removal port 7 fixed thereto to swing, thereby increasing the dust suction range of the dust removal port 7. Since the upper part of the dust removal port 7 is connected to the filter box 5 through the telescopic tube 6, the movement of the dust removal port 7 can be guaranteed;

[0032] As attached Figure 1 , Attachment Figure 4 and attached Figure 5 As shown in , the filter plate is placed in the dust box 13 to facilitate filtering debris and dust. When the filter plate needs to be replaced, the limit block 11 is rotated on the filter box 5, and the limit block 11 compresses the return spring 12, so that the limit block 11 is separated from the close fit with the dust box 13, and the dust box 13 is pulled upward to separate the dust box 13 from the card slot connection with the filter box 5, so that the filter plate connected to the card slot in the dust box 13 can be taken out, and a new filter plate can be placed in the dust box 13, and the dust box 13 and the filter box 5 card slot connection can be made, and the limit block 11 is loosened. The return spring 12 pushes the limit block 11 to reset, so that the limit blocks 11 on the front and rear sides of the filter box 5 are in close fit with the dust box 13, and the limit blocks 11 symmetrically distributed on the left and right play a limiting role on the dust box 13;

[0033] As attached Figure 1 and attached Figure 6 As shown in , when the tool 14 needs to be replaced, the mounting block 17 is pushed upward so that the mounting block 17 is retracted into the mounting rod 15, the spring piece 16 installed above the mounting block 17 is compressed, and then the mounting rod 15 connected to the slot therewith is taken out from the tool holder 3 and the tool 14, and the tool 14 can be taken out from the tool holder 3, and the new tool 14 is connected to the slot below the tool holder 3, and the mounting rod 15 is inserted into the tool holder 3 and the tool 14, and the elastic action of the spring piece 16 pushes the mounting block 17 to pop out from under the mounting rod 15, thereby fixing the tool holder 3 and the tool 14.
