Technical Field
[0001] The invention relates to the field of computer processing, and in particular to a punching and hole-making device for computer processing. Background Art
[0002] A computer case is made of sheet metal that is cut and punched. During processing, the side panels of the case need to be provided with long through holes at the top of the side walls for installing various control keys or components. However, when punching holes in the sheet metal, the existing punching devices generate scattered debris that is difficult to recycle. In addition, the punching device cannot effectively ensure that the sheet metal does not shift during the punching process, which can easily cause the sheet metal to shift and cause the punching position to be misaligned.

[0010] As a preferred solution, both end surfaces of the push plate are on the same vertical line with the corresponding end surfaces of the limit plate.
[0011] As a preferred solution, the punching mechanism and the pressure rod are staggered.
[0012] The beneficial effects of the present invention are as follows: when the present invention is used, the limit plate is fixed at the corresponding position on the top of the base by bolts as required, so that when the metal sheet is laid flat on the base, one side of it abuts against the right end surface of the baffle plate, and the rear side abuts against the limit plate, thereby limiting the continued movement of the metal sheet, while the punching position on the metal sheet is located directly below the punching mechanism, so that the metal sheet can be placed in the designated area on the top of the base through the baffle plate and the limit plate; at the same time, the electric push rod I drives the connecting plate to drive the pressure rod to slide down into the U-shaped notch, so that the downward-moving pressure rod can press the metal on the base The metal sheet plays a role of pressing down and fixing to prevent it from being displaced and affecting the punching work when punching the metal sheet later; the hydraulic rod drives the mounting plate, the vertical rod, the box body and drives the cutting knife group to move downward to punch the metal sheet, and the cut debris fills the opening of the cutting knife group. When the debris in the opening gradually increases and is under pressure, it will slowly move upward in the opening of the cutting knife group, and finally the debris overflows into the box body through the top opening of the cutting knife group for temporary storage. After a certain period of time, the debris is taken out through the top opening of the box body to prevent the debris from scattering all over the ground. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The following are examples and the attached Figure 1-3 , the technical solution of the present invention is further specifically described.
[0018] A punching and hole-making device for computer processing, comprising a workbench 1, wherein a frame 2 is arranged on the top of the workbench 1, and a punching mechanism 3 is arranged on the frame 2, a base 4 is arranged above the workbench 1, wherein a baffle 5 is arranged on one side of the top of the base 4, and a plurality of groups of U-shaped notches 6 are arranged on the top of the baffle 5, and a pressure rod 7 extending to the top of the base 4 is arranged in the U-shaped notch 6, and the punching mechanism 3 and the pressure rod 7 are staggered, wherein the plurality of groups of pressure rods 7 are connected to a connecting plate 8 on one side of the baffle 5, and an electric push rod 19 connected to the bottom of the connecting plate 8 is arranged on the outside of the base 4, and an extension plate 14 for fixing the electric push rod 19 is arranged on one side of the base 4;
[0019] A limit plate 10 is also provided at the edge of the base 4 and is vertically arranged with the baffle 5, wherein the limit plate 10 is fixed to the base 4 by bolts, and a rectangular notch 11 is provided in the middle of the bottom of the limit plate 10, and a push plate 12 driven by an electric push rod II13 is provided in the rectangular notch 11;
[0020] The punching mechanism 3 includes a hydraulic rod 31 arranged on the frame 2, wherein a mounting plate 32 is arranged on the output shaft of the hydraulic rod 31, and the mounting plate 32 is connected to a box body 34 with an open top through a vertical rod 33, and a cutting knife group 35 is arranged in the middle of the bottom of the box body 34.
[0021] In this embodiment, the cutting knife set 35 is surrounded by blades, wherein a blade portion is provided at the top of the side wall of the blade. The top of the cutting knife set 35 extends into the opening of the box body 34 , wherein the cutting knife set 35 is fixedly connected to the bottom wall of the box body 34 .
[0022] like Figure 2 As shown, the bottom end of the limiting plate 10 is bent toward the back side thereof to form a bent portion 15 , wherein the bent portion 15 is fixed to the base by bolts, and the electric push rod II13 is fixed to the bent portion 15 .
[0023] In this embodiment, both end surfaces of the push plate 12 are located on the same vertical line as the corresponding end surfaces of the limiting plate 10 .
[0024] The working principle of the present invention is as follows: when in use, the limiting plate 10 is fixed to the corresponding position on the top of the base 4 by bolts as required, so that when the metal sheet is laid flat on the base 4, one side thereof abuts against the right end surface of the baffle 5, and the rear side abuts against the limiting plate 10, thereby limiting the continued movement of the metal sheet, and the punching position on the metal sheet is located directly below the punching mechanism 3, so that the metal sheet is placed at the designated area on the top of the base 4 through the baffle 5 and the limiting plate 10;
[0025] At the same time, the electric push rod 19 drives the connecting plate 8 to drive the pressure rod 7 to slide down into the U-shaped notch 6, so that the downwardly moved pressure rod 7 can play a downward pressing and fixing role on the metal sheet on the base 4 to prevent it from being displaced and affecting the punching work when punching the metal sheet later;
[0026] The hydraulic rod 31 drives the mounting plate 32, the vertical rod 33, the box body 34 and the cutting knife group 35 to move downward to punch holes in the metal sheet, and the cut debris is filled into the opening of the cutting knife group 35. When the debris in the opening gradually increases and is under pressure, it will slowly move upward in the opening of the cutting knife group 35, and finally the debris will fall into the box body 35 through the top opening of the cutting knife group 35 for temporary storage. After a certain period of time, the debris will be taken out through the top opening of the box body 35 to prevent the debris from being scattered all over the floor.
[0027] After the drilling is completed, the electric push rod I9 drives the connecting plate 8 to drive the pressure rod 7 to move upward to loosen the metal sheet, then the electric push rod II13 can drive the push plate 12 to slide forward from the rectangular notch 11, and then push the metal sheet forward on the base 4 to facilitate the removal of the metal sheet from the base 4 under the pressure rod 7.
[0028] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
