DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 A punching device for mechanical processing includes a placing table 1 and a dustproof plate 2. The placing table 1 is used to place the product that needs to be punched on the placing table 1. The top of the placing table 1 is slidably connected with symmetrical clamps 3. The two clamps 3 are located at both ends of the top of the placing table 1 to clamp the product that needs to be punched. A punching groove 4 is opened at the center of the top of the placing table 1. The puncher 18 punches holes in the product and then penetrates into the punching groove 4.

[0025] A support column 5 is fixedly provided in the middle of the edge in the length direction of the placing platform 1. A motor is installed on the top of the support column 5, and a U-shaped slot is provided in the direction of the placing platform 1. A vertical first screw is rotatably installed in the U-shaped slot. A horizontal column 6 is slidably connected to the first screw. A vertical state is formed between the horizontal column 6 and the support rod. By starting the motor on the support column 5, the output end of the motor drives the first screw to rotate, thereby driving the horizontal column 6 to slide vertically up and down on the first screw. The horizontal column 6 is installed with a motor at one end away from the support column 5, and the bottom of the horizontal column 6 has a U-shaped slot, a second screw is installed in the U-shaped slot, and a punching device is slidably connected below the second screw. When the motor on the horizontal column 6 is started, the output end of the motor drives the second screw to rotate, thereby causing the punching device to slide horizontally on the second screw. For the above sliding structure, please refer to the patent document with the prior art publication number CN206743413U, which discloses the sliding technical solution of this application.

[0026] In this embodiment, the punching device includes a driving motor 17 slidably connected under the horizontal column 6, the output end of the driving motor 17 is fixedly connected to the puncher 18, the end of the puncher 18 is facing the hole piercing port 9, the driving motor 17 is started, and the output end of the driving motor 17 drives the puncher 18 to rotate at a high speed to drill holes in the products that need to be punched.

[0027] In this embodiment, the dustproof plate 2 is located directly below the horizontal column 6, which can effectively prevent dust from being adsorbed on the iron filings produced during punching; a hinged rod 8 is rotatably connected between the slider 7 and the horizontal column 6; and a through-hole 9 for a punching device to pass through the dustproof plate 2 is provided in the middle of the dustproof plate 2, so that the punching device can punch holes in the punching objects under the dustproof plate 2;

[0028] In this embodiment, the dustproof plate 2 is divided into two parts by the machine opening 9 above, and grooves 10 for the sliding blocks 7 to slide are provided above the two parts, and the distances between the two grooves 10 and the machine opening 9 are equal. U-shaped frames 11 are fixedly connected to both sides of the horizontal column 6 and above the two sliding blocks 7 to limit the hinged rod 8. The two ends of the hinged rod 8 are respectively rotated in the U-shaped frames 11 inclined at two positions. The downward movement of the horizontal column 6 drives the dustproof plate 2 to move downward as a whole. When the dustproof plate 2 coincides with the splint 3, the dustproof plate 2 cannot descend, and the horizontal column 6 will drive the punching device to continue to descend. Therefore, a descending force will be generated during the descent of the horizontal column 6. When the sliding block 7 is affected by the descending force, it will slide in the parallel direction of the groove 10, and then the hinged rod 8 will follow the movement of the sliding block 7 to unfold, so that the punching device can contact the product to be punched and complete the punching process.

[0029] A symmetrical first straight groove 12 and a second straight groove 13 are provided in both length directions above the placement table 1; two guide blocks 14 sliding in the first straight groove 12 and the second straight groove 13 are fixedly connected below the splint 3; a cylinder 15 is fixed in the length direction of the first straight groove 12 to facilitate the sliding of the guide block 14 on the cylinder 15, and a bidirectional screw 16 is rotatably connected in the length direction of the second straight groove 13, and the bidirectional screw 16 and the guide block 14 are threadedly matched. When the motor on the placement table 1 is started, the motor drives the bidirectional screw 16 to rotate so that the two splints 3 move relative to each other in the second straight groove 13, and because the splint 3 is fixedly connected to the guide blocks 14 of the two straight grooves at the same time, one end of the splint 3 slides in the second straight groove 13 while also driving the splint 3 to slide synchronously in the guide block 14 of the first straight groove 12.

[0030] Reference Figure 4 A detachable magnetic sheet is installed at the bottom of the dustproof plate 2, and an open opening 19 is provided at the bottom of the dustproof plate 2 and the inner sides of the two plywood 3. The sides of the dustproof plate 2 and the plywood 3 are provided with a long strip socket 20 connected to the open opening 19. The depth of the long strip socket 20 is slightly greater than the length of the open opening 19. The magnetic sheet slides in the parallel direction of the long strip socket 20. The shape of the magnetic sheet corresponds to the shape on the dustproof plate 2. The magnetic sheets are respectively inserted into the dustproof plate 2 and the plywood 3 through the long strip socket 20 to absorb the iron filings generated during punching. When the iron filings accumulate to a certain extent, they are removed and replaced with new magnetic sheets. This can not only prevent the damage to the human body caused by the splashing of iron filings, but also prevent the wear and tear of the machinery caused by the accumulation of splashing iron filings.

[0031] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0032] The functional principle of the utility model can be explained through the following operation modes:

[0033] After the product that needs to be punched is placed on the placement table 1, the motor on the placement table 1 is started. The output end of the motor drives the bidirectional screw 16 to rotate, and then drives the guide block 14 on the screw to slide relatively. Since the guide block 14 is fixedly connected to the clamping plate 3, the two clamping plates 3 are driven to slide in relative directions to clamp the product that needs to be punched; start the motor on the support rod, the output end of the motor drives the first screw to rotate and then drives the horizontal column 6 to slide up and down. After the horizontal column 6 moves downward, the horizontal column 6 drives the placement table 1 to move down as a whole until it is engaged with the two clamping plates 3, thereby forming a U-shaped space to prevent debris from splashing. At this time, the horizontal column 6 continues to move downward, and the hinged rod 8 slides to both sides under the guidance of the slider 7 until the puncher 18 punches holes corresponding to the position of the object that needs to be punched; when punching iron products, iron filings will be generated. Since a removable magnetic sheet is provided on the clamping plate 3 and the dustproof plate 2, the iron filings will be attracted by the magnetic sheet in time. The magnetic sheet can be replaced irregularly according to the situation.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
