Detailed Description of the Embodiment

[0019] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0020] To better understand the above technical solution, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be completely conveyed to those skilled in the art.

[0021] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0022] An embodiment of the present utility model provides a punching device, which includes a base 100 and a punching mechanism 200.

[0023] Specifically, a material table 110 is provided on the base 100, and the material table 110 is used to place the material to be punched. At least one punching groove is provided on the material table 110. It should be understood that the cross-sectional shape of the punching groove is adapted to the shape of the required punching hole. Those skilled in the art can determine the number and shape of the punching grooves to be provided according to actual implementation needs. For example, the number of punching grooves can be one, two, or four, etc.

[0024] The punching mechanism 200 is arranged above the material table 110. The punching mechanism 200 includes a lifting drive assembly 210 and at least one punching column 220. It should be understood that the number and shape of the punching columns 220 can be adapted to the number and shape of the punching grooves. Of course, the number of punching columns 220 can also be less than the number of punching grooves. For example, the number of punching grooves is four, and the number of punching columns 220 is one or two, etc.

[0025] At least one stamping post 220 is drivingly connected to the lifting drive assembly 210. Thus, at least one stamping post 220 can be inserted into the stamping groove along the axial direction of the stamping groove under the drive of the lifting drive assembly 210, so as to punch the material placed on the material table 110. And, a ventilation hole 221 connected to an air pump is provided on the bottom surface of each stamping post 220. When one punching is completed, the air pump can blow air out through the ventilation hole 221 to remove the waste adhered to the bottom of the stamping post 220, so that the next punching can be carried out quickly, improving the punching efficiency. In one example, the ventilation hole 221 can be coaxially arranged with the stamping post 220, so that the gas blown out from the ventilation hole 221 can act vertically on the adhered waste, ensuring the waste removal effect.

[0026] In some embodiments of the present utility model, the bottom surface of each stamping post 220 has two inclined surfaces 222 intersecting along its radial direction, so that the intersecting position of the two inclined surfaces 222 protrudes from other positions. Thus, when punching, since this intersecting position protrudes from other positions, it can first contact the surface of the material. Compared with direct planar contact, it can increase the pressure on the surface of the material, thereby improving the punching efficiency. It should be noted that in other embodiments, the bottom surface of the stamping post 220 can also have only one, or more than two inclined surfaces 222, as long as it can increase the pressure of the stamping post 220 on the surface of the material.

[0027] In an embodiment of the present utility model, the lifting drive assembly 210 includes a lifting drive member 211 and a mounting plate 212. The mounting plate 212 is located below the lifting drive member 211 and is drivingly connected to the lifting drive member 211. At least one stamping post 220 is arranged on the bottom surface of the mounting plate 212 and faces downward. Thus, the lifting drive member 211 synchronously drives at least one stamping post 220 to move through the mounting plate 212, which can ensure the synchronism of the movement of at least one stamping post 220. In one example, the lifting drive member 211 can be a cylinder.

[0028] In one embodiment, the stamping mechanism 200 further includes a pressing component 230. The pressing component 230 includes a pressing plate 231 and at least one elastic support unit 232. The elastic support unit 232 includes a guide post and an elastic member. The guide post passes through the mounting plate 212 from top to bottom to be connected to the pressing plate 231, and the elastic member is sleeved on the guide post and its two ends are respectively abutted against the mounting plate 212 and the pressing plate 231. And, a through hole for the stamping post 220 to pass through is provided on the pressing plate 231. It should be noted that before punching, the position of the pressing plate 231 is below the stamping post 220, or the bottom surface of the pressing plate 231 is lower than the bottom surface of the stamping post 220.

[0029] Thus, when punching is performed, the lifting driving member 211 can drive the pressing assembly 230 to move downward synchronously. The bottom surface of the pressing plate 231 can contact the surface of the material prior to the bottom surface of the punching column 220. The elastic member can apply a downward elastic force to the pressing plate 231, so that the pressing plate 231 can stably press the material on the material table 110 to prevent it from shifting. Then, the punching column 220 contacts the material to perform punching, ensuring the punching effect.

[0030] In one example, when the number of punching columns 220 is two or more than two, the through holes on the pressing plate 231 can be strip-shaped holes, so as to be able to press around the position to be punched on the material, preventing the material from shifting due to the pressure of the punching columns 220.

[0031] In one embodiment, to ensure the stability of pressing, the number of the elastic support units 232 can be two. The two elastic support units 232 are respectively arranged on both sides of the at least one punching column 220. Thus, the arrangement of the two elastic support units 232 can apply the same magnitude of elastic force to both ends of the pressing plate 231, further ensuring the stability of the contact between the pressing plate 231 and the material, and avoiding the material from shifting during punching due to uneven acting forces.

[0032] In one example, a limiting portion is provided at one end of the guiding column close to the lifting driving member 211, so as to prevent the guiding column from disengaging from the mounting plate 212 from top to bottom. The limiting portion can be a boss, a rib, a protrusion or a bump protruding along the radial direction of the guiding column, etc. It can also be a combination of the foregoing multiple structures, and no special limitation is made thereto.

[0033] In some embodiments of the present utility model, the punching device further includes a mounting bracket 300. The mounting bracket 300 is erected on the base 100 and is located above the material table 110. Specifically, the mounting bracket 300 includes a top plate 310 and vertical plates 320 connected to both ends of the top plate 310. The two vertical plates 320 are respectively erected on both sides of the material table 110, and the top plate 310 is horizontally connected to the tops of the two vertical plates 320. The output shaft of the lifting driving member 211 passes through the top plate 310 from top to bottom and is connected to the mounting plate 212, that is to say, the mounting plate 212 is located between the two vertical plates 320.

[0034] Next, guide rails are provided on the side walls of the two vertical plates 320 that face each other (i.e., the two side walls adjacent to the mounting plate 212). The guide rails are arranged vertically, and both ends of the mounting plate 212 are provided with sliders adapted to the guide rails. Thus, through the arrangement of the guide rails and the sliders, it can play a guiding role when the mounting plate 212 moves, preventing the mounting plate 212 from shifting. Moreover, when the punching column 220 contacts the material, due to the action of the guide rails and the sliding rails, it can also prevent the punching column 220 from shifting when subjected to a force, ensuring its punching effect.
