DETAILED DESCRIPTION

[0021] 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.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A metal machining punching and punching device comprises a platform 1, a placement plate is fixedly mounted on the upper surface of the platform 1, a positioning mechanism for fixing the metal plate is arranged above the platform 1, a hydraulic cylinder 2 is fixedly mounted on the lower surface of the placement plate, and a punching head 3 is fixedly mounted on the bottom end of the driving shaft of the hydraulic cylinder 2;

[0024] A waste collection box 4 is fixedly installed on the surface of the platform 1, and a scraper rod 5 is horizontally slidably arranged on the surface of the placement plate through a sliding component. The sliding component includes two symmetrical and horizontal slide grooves 10 opened on the surface of the placement plate and two sliders 11 respectively slidably arranged in the two slide grooves 10. The ends of the two sliders 11 close to each other are fixedly connected to the side walls of the scraper rod 5. An inclined plate 6 is symmetrically fixedly installed on the upper surface of the scraper rod 5. A sliding opening 7 is opened on the surface of the inclined plate 6. A mounting rod 8 is fixedly installed on the driving shaft surface of the hydraulic cylinder 2. A pressure rod 9 is fixedly installed on the left and right side walls of the mounting rod 8. The ends of the two pressure rods 9 away from each other are respectively slidably arranged in the two sliding openings 7.

[0025] First, the metal plate is positioned by the positioning mechanism, and then the hydraulic cylinder 2 is started to make the punching head 3 move downward quickly. During the downward movement, the two pressure rods 9 will slide in the two sliding openings 7 respectively. Under the action of the inclined pressure, the scraper rod 5 will move in the horizontal direction. When the punching is completed, the hydraulic cylinder 2 moves up with the punching head 3, and the scraper rod 5 will also move and reset. During the resetting process, the scraper rod 5 will push the waste generated during the punching process into the waste collection box 4, thereby completing the cleaning without the need for manual time to clean.

[0026] A plurality of rolling balls are rotatably embedded on the lower surface of the scraper rod 5, and the plurality of rolling balls are in rolling contact with the platform body 1;

[0027] The rolling ball can reduce the friction between the contact surface of the scraper rod 5 and the platform body 1, thereby avoiding jamming during movement.

[0028] The positioning mechanism includes a first threaded rod 12 with opposite thread directions at the left and right ends and two L-shaped clamping plates 13 symmetrically threadedly sleeved on the first threaded rod 12. Both ends of the first threaded rod 12 are rotatably connected to the surface of the placement plate. The two clamping plates 13 are restricted in rotation by a limiting component. The limiting component includes a sliding rod 17. Both ends of the sliding rod 17 are fixedly connected to the surface of the placement plate. The two clamping plates 13 are slidably sleeved on the sliding rod 17.

[0029] When the metal plate needs to be positioned, the metal plate is first placed between the two clamping plates 13, and then the two clamping plates 13 are controlled to move relative to each other in the horizontal direction by rotating the first threaded rod 12, until the two clamping plates 13 are tightly against the metal plate, the positioning of the metal plate is completed. Metal plates of different sizes can be positioned, which is very practical, and the positioned metal plate is basically in a suspended state, thereby preventing the punching head 3 from contacting the table 1 when passing through the metal plate.

[0030] A second threaded rod 14 is vertically rotatably mounted on the upper surface of the clamping plate 13, an L-shaped connecting rod 15 is threadedly sleeved on the second threaded rod 14, and a pressing plate 16 is fixedly mounted on the bottom end of the connecting rod 15;

[0031] When the two clamping plates 13 complete the horizontal positioning of the metal plate, the second threaded rod 14 is rotated to control the connecting rod 15 to move the pressure plate 16 in the vertical direction until the pressure plate 16 is tightly against the metal plate. The longitudinal positioning of the metal plate is completed, thereby improving the stability of the positioned metal plate.

[0032] In the utility model, the metal plate is first positioned by the positioning mechanism, and then the hydraulic cylinder 2 is started to make the punching head 3 move downward quickly. During the downward movement, the two pressure rods 9 will slide in the two sliding openings 7 respectively. Under the action of the inclined surface pressure, the scraper rod 5 will move in the horizontal direction. When the punching is completed, the hydraulic cylinder 2 moves up with the punching head 3, and the scraper rod 5 will also move and reset. During the resetting process, the scraper rod 5 will push the waste generated during the punching process into the waste collection box 4, thereby completing the cleaning without the need for manual time to clean.

[0033] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[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.
