[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] As Figures 1 to 4 shown, a surface punching device for hardware metal products according to an embodiment of the present utility model includes a punching machine 1; a cylinder 11 is fixedly connected to the top of the inner side wall of the punching machine 1; a punch head 12 is installed at the output end of the cylinder 11; an aggregate hole 18 is opened at the bottom of the inner side wall of the punching machine 1; the aggregate hole 18 is arranged directly below the punch head 12; a fixed plate 13 is fixedly connected to the middle of the punch head 12; a first spring telescopic rod 14 is fixedly connected to the bottom side wall of the fixed plate 13; the end of the first spring telescopic rod 14 is fixedly connected to a fixed box 15; a fan 16 is fixedly connected to the top of the inner side wall of the punching machine 1; an air duct 17 is fixedly connected to the output end of the fan 16; the end of the air duct 17 is fixedly connected to the side wall of the fixed box 15, and the air duct 17 and the fixed box 15 are in communication with each other; the opening direction of the fixed box 15 faces the punch head 12. During work, the metal product to be punched is placed inside the punching machine 1, and then the metal product is pushed towards the punch head 12 so that the part to be punched is placed directly below the punch head 12 and directly above the aggregate hole 18. At this time, by turning on the switch of the cylinder 11, the cylinder 11 drives the punch head 12 to punch the metal product, and then by turning on the switch of the fan 16, the fan 16 conveys air flow into the air duct 17, and the air flows towards the punch head 12 through the fixed box 15. Because the fixed box 15 is located below the punch head 12, during the continuous descent of the punch head 12, the fixed box 15 will first contact the surface of the metal product, and then the air flowing towards the punch head 12 through the fixed box 15 will blow off the impurities on the metal surface. When the punch head 12 punches the metal product, the impurity residue on the metal surface is reduced, the punching is safer, the wear of the punch head 12 by impurities is reduced, and the service life of the punch head 12 is improved.
[0025] As Figures 1 to 4 shown, a second spring telescopic rod 2 is fixedly connected to the bottom side wall of the fixing plate 13; a collection box 21 is fixedly connected to the end of the second spring telescopic rod 2; the collection box 21 and the first spring telescopic rod 14 are symmetrically arranged. During operation, by providing a collection box 21 below the fixing plate 13, after the fan 16 is turned on, air will be delivered to the fixing box 15 through the air duct 17. At this time, the fixing box 15 blows air in the direction of the punch 12, so that the impurities on the surface of the metal product are cleaned away from the punch 12. The cleaned impurities will fall into the collection box 21. After punching is completed, the impurities are centrally cleaned by the collection box 21, reducing the problem of impurity dispersion and environmental pollution, and improving the protection effect on the working environment.
[0026] As Figure 4 shown, a through groove 32 is opened at the top of the collection box 21; a pair of guide plates 31 are slidably connected to the bottom side wall of the collection box 21; a baffle 3 is fixedly connected to the top end of the guide plate 31; the top of the baffle 3 is arranged inside the through groove 32, and the baffle 3 and the through groove 32 are slidably connected. During operation, by providing a baffle 3 on the collection box 21, when the punch 12 moves towards the surface of the metal product, the lowermost guide plate 31 will be squeezed and slide upward by the metal product, and then the baffle 3 will be pushed out of the collection box 21 through the through groove 32 to the outside of the collection box 21. At this time, the dust and impurities blown by the fixing box 15 enter the collection box 21. During the process of the punch 12 rising after punching is completed, the baffle 3 slides downward and drops due to its own gravity, thereby realizing the shielding of the collection box 21, reducing the possibility of impurities inside the collection box 21 falling to the outside, and improving the collection effect of the collection box 21.
[0027] As Figure 2 and Figure 5As shown in the figure, multiple groups of grooves 4 are opened at the bottom of the inner side wall of the punching machine 1; the grooves 4 are arranged in an array on the punching machine 1; multiple groups of third spring telescopic rods 41 are fixedly connected to the bottom of the inner side wall of the grooves 4; the top ends of the third spring telescopic rods 41 are fixedly connected to a support frame 42; a roller 43 is rotatably connected to the middle of the support frame 42. During operation, by providing the roller 43 on the punching machine 1, during the process of conveying the metal product, by placing the metal product on the roller 43, at this time, the bottom of the metal product is in contact with the top of the roller 43, and the roller 43 is in a rotating state during the movement process. At this time, the sliding friction between the metal product and the surface of the punching machine 1 is replaced by the rolling friction between the metal product and the roller 43, thereby reducing the friction loss of the roller 43. When the metal product is punched, it is pressed by the punch 12, causing the metal product to drive the roller 43 to move downward. When the metal product comes into contact with the surface of the punching machine 1, the punching operation starts. At this time, both the roller 43 and the support frame 42 move into the groove 4. After the punching is completed, under the elastic action of the third spring telescopic rod 41, the roller 43 drives the metal product to reset, and then the completed metal product is continuously conveyed.
[0028] As Figures 1 to 3 shown, multiple groups of electric push cylinders 5 are fixedly connected to the side wall of the punching machine 1; the electric push cylinders 5 are symmetrically arranged on the punching machine 1; the output end of the electric push cylinder 5 penetrates through the side wall of the punching machine 1 and is fixedly connected to a clamping plate 51; the bottom of the clamping plate 51 is in contact with the inner side wall of the punching machine 1. During operation, by providing the electric push cylinder 5 on the punching machine 1, when punching, the switch of the electric push cylinder 5 is turned on, causing the electric push cylinder 5 to drive the clamping plate 51 to move closer to the middle, thereby enabling a pair of clamping plates 51 to squeeze and fix the metal product, making the metal product more stable during the punching process and improving the stability of the metal product during punching.
[0029] As Figure 1 shown, a waste collection box 6 is provided at the bottom of the punching machine 1; the waste collection box 6 is arranged below the aggregate hole 18. During operation, by providing the waste collection box 6 below the punching machine 1, the waste generated by punching can be recycled, improving the recycling effect and reducing the production cost.
[0030] Working principle: Place the metal product to be punched inside the punching machine 1, then push the metal product towards the punch 12, so that the part to be punched is placed directly below the punch 12 and directly above the aggregate hole 18. At this time, turn on the switch of the cylinder 11 to drive the punch 12 to punch the metal product. Then turn on the switch of the fan 16 to make the fan 16 convey air into the air duct 17. The air flows towards the punch 12 through the fixed box 15. Since the fixed box 15 is located below the punch 12, during the continuous descent of the punch 12, the fixed box 15 will first contact the surface of the metal product, and then the air flowing towards the punch 12 through the fixed box 15 will blow off the impurities on the metal surface. When the punch 12 punches the metal product, the impurity residue on the surface of the metal product is reduced, making the punching safer, reducing the wear of the punch 12 by impurities, and increasing the service life of the punch 12.
[0031] By providing a collection box 21 below the fixed plate 13, after the fan 16 is turned on, it will convey air to the fixed box 15 through the air duct 17. At this time, the fixed box 15 blows air towards the punch 12, so that the impurities on the surface of the metal product are cleaned away from the punch 12. The cleaned impurities will fall into the collection box 21. After punching is completed, the collection box 21 is used to centrally clean the impurities, reducing the problem of impurity dispersion and environmental pollution, and improving the protection effect on the working environment.
[0032] By providing a baffle 3 on the collection box 21, when the punch 12 moves towards the surface of the metal product, the lowermost guide plate 31 will be squeezed by the metal product and slide upwards, thereby pushing the baffle 3 out of the collection box 21 through the through groove 32 to the outside of the collection box 21. At this time, the dust and impurities blown by the fixed box 15 enter the collection box 21. During the process of the punch 12 rising after punching, the baffle 3 slides downwards and drops due to its own gravity, thereby realizing the shielding of the collection box 21 and reducing the possibility of impurities inside the collection box 21 falling to the outside, improving the collection effect of the collection box 21.
[0033] By providing a roller 43 on the punching machine 1, during the transportation of metal products, by placing the metal products on the roller 43, at this time, the bottom of the metal products is in contact with the top of the roller 43. During the movement, the roller 43 is in a rotating state. At this time, the sliding friction between the metal products and the surface of the punching machine 1 is replaced by the rolling friction between the metal products and the roller 43, thereby reducing the frictional loss of the roller 43. When the metal products are punched, they are pressed by the punch 12, causing the metal products to drive the roller 43 to move downward. When the metal products come into contact with the surface of the punching machine 1, the punching operation starts. At this time, both the roller 43 and the support frame 42 move into the groove 4. After the punching is completed, under the elastic action of the third spring telescopic rod 41, the roller 43 drives the metal products to reset, and then continues to transport the completed metal products.
[0034] By providing an electric push cylinder 5 on the punching machine 1, when punching, the switch of the electric push cylinder 5 is turned on, so that the electric push cylinder 5 drives the clamping plates 51 to move closer to the middle, and then the pair of clamping plates 51 squeeze and fix the metal products, making the metal products more stable during the punching process and improving the stability of the metal products during punching.
[0035] By providing a waste collection box 6 below the punching machine 1, the waste generated by punching can be recycled, improving the recycling effect and reducing the production cost.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
