[0022] This embodiment provides a punching and shearing machine, as Figure 1 and Figure 2 shown, which includes a punching and shearing machine body 1. A punching and shearing cylinder 2 is provided on the punching and shearing machine body 1. An installation plate 22 is fixedly connected to the piston end 21 of the punching and shearing cylinder 2, and a punching and shearing head 23 is connected to the bottom of the piston end 21 of the punching and shearing cylinder 2; a pressing mechanism 3 is provided on the installation plate 22; the punching and shearing machine body 1 is connected to a workbench 4 through a plurality of support columns 41. A punching hole 42 for the punching and shearing head 23 to pass through is provided on the workbench 4. A discharge plate 5 with an inclined slope 51 is fixedly installed directly below the punching hole 42; a waste collection box 6 is connected to the adjacent side of the bottom end of the slope of the discharge plate 5. A collection cover 61 is connected to the side of the waste collection box 6. The collection cover 61 is provided with a notch 611. A blowing fan 7 that is flush with the workbench 4 and faces the notch 611 is installed on the punching and shearing machine body 1.

[0023] Working principle: When punching and shearing operations are to be performed, the piston end 21 of the punching and shearing cylinder 2 is driven to make the clamping mechanism 3 and the punching and shearing head 24 synchronously move downward to the workbench 4 for punching and shearing. Part of the debris and waste generated during punching and shearing slides down to the collecting cover 61 and the waste collecting box 6 through the inclined slope 51 of the discharge plate 5 along with the punching hole 42, while part of the debris and waste on the workbench 4 is blown into the collecting cover 61 by the blowing fan 7. The notch 611 of the collecting cover 61 covers the workbench 4 and can collect the debris and waste to a large extent, solving the problem that when punching holes 42 in metal, some metal debris and metal waste are generated, and the metal waste and debris fall on the processing table, requiring the user to clean them frequently, thereby further improving the punching rate problem 42.

[0024] In this embodiment, if Figure 2 As shown, at least one pair of clamping mechanisms 3 are symmetrically provided on the mounting plate 22, and the clamping mechanism 3 includes a guide column 31, a pressure plate 32 and a spring 33. The pressure plate 32 is installed at one end of the guide column, and the other end is slidably connected to the mounting plate 22. The spring 33 is sleeved on the guide column 31 and is located between the mounting plate 22 and the pressure plate. That is, through this arrangement, during punching and shearing, the clamping mechanism and the workbench interact with each other to clamp the steel plate to be processed. When the piston end 21 continues to move downward, the pressure plate 32 presses the steel plate under the action of the spring, and the punching and shearing head 24 continues to move downward and punches and shears the steel plate. The clamping mechanism ensures the stability of the punching and shearing head 24 when it is working.

[0025] In this embodiment, if Figure 2 As shown, baffles 52 are provided on both sides of the inclined slope 51 of the discharge plate 5. By providing the baffles 52, the debris and waste falling from the punching hole 42 can be better limited to prevent them from scattering to other locations when the inclined slope 51 slides down.

[0026] In this embodiment, if Figure 2 As shown, a clamping block is provided at the bottom of the discharge plate 5 and is clamped with the punching and shearing machine body 1 through the clamping block. The discharge plate 4 can be replaced and disassembled as needed by clamping it through the clamping block, which is convenient and quick.

[0027] In this embodiment, the cross section of the collecting cover 61 is trapezoidal. Figure 2 As shown, the width of the notch 611 of the collecting cover 61 is greater than the distance between the baffles 52, and the length of the notch 611 of the collecting cover 61 is greater than the distance from the workbench 4 to the punching and shearing machine body 1. The notch 611 covers the workbench 4 and the unloading plate 4, which can collect debris and waste to a large extent, thereby solving the problem that when punching 42 in metal, some metal debris and metal waste are generated, and the metal waste and debris fall on the processing table, requiring the user to clean them frequently, thereby further improving the punching rate 42.

[0028] In this embodiment, a negative pressure fan 62 is connected to the bottom of the waste collection box 6. By setting the negative pressure fan 62, a wind channel is formed between the blowing fan 7 and the negative pressure fan 62. This wind channel extends from the workbench 4 to the collection hood 61 and then to the waste collection box 6, enabling more efficient and comprehensive collection of metal waste and debris. Of course, the waste collection box 6 can be detachable, or it can be provided with a crushing and cleaning device inside for collection and treatment after crushing and cleaning.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
