Description

Punch needle for removing holes Bian Maoci Technical Field The utility model relates to the field of punching, in particular to a punching needle for removing holes Bian Maoci. Background As shown in fig. 1-2, there are many punching objects, plastics, profiles, etc. as a punching pin, an appliance for punching. Under the feedback of current customers, when punching carrier tapes of polyimide film, polyamide materials, benzocyclobutene films, polyethylene terephthalamide, acid ester films (PET), polystyrene (PS high transmittance, PS fog transmittance, PS black), polycarbonate (PC), ABS, H IPS, PE and the like, burrs exist on the inner edges of the holes, and based on the problem, the needle heads of punching needles have iterated in multiple versions, such as flat head D, V opening E and bevel F, but the punched holes are all provided with burrs. Disclosure of utility model In order to solve the problems, the utility model provides a punching needle for removing holes Bian Maoci, which aims to solve the problem of burrs at the edges of the holes. The utility model adopts the technical scheme that the punching needle for removing the hole Bian Maoci comprises a needle handle and a needle head formed on the end part of the needle handle, wherein the needle head is formed with punched holes on a high polymer material or a plastic film material. The utility model has the beneficial effects that: The arch structure used in the utility model can solve the problem of burrs during punching, the material is firstly contacted to generate pre-compression stress, and then the extension part continuously punches the material, so that a shearing surface with a raised smooth surface is obtained. Further, the extension is in the shape of a boss. Further, the edge of the extension coincides with the edge of the needle. Further, there is a space between the edge of the extension and the edge of the needle. Further, the tip of the extension coincides with the central axis of the needle shaft. Further, the tip of the extension is offset from the central axis of the needle shaft. Further, the sides of the boss are concave. Further, the extension is in the shape of a cylinder. Further, the extension part is formed by overlapping a plurality of flat bodies with circular outlines, and the diameters of the flat bodies are sequentially increased or decreased along a single direction. Further, the needle handle is one of a round needle, a flat needle and an elliptic needle. Drawings Fig. 1 is a perspective view of the prior art. Fig. 2 is an enlarged schematic view at a of fig. 1. Fig. 3 shows the effect of punching a hole with burrs observed by the apparatus when punching a hole with the existing needle structure. Fig. 4 is a view showing the effect of a hole punched through a needle of the present utility model using an apparatus. Fig. 5 is a perspective view of six embodiments. Fig. 6 is a side view of fig. 5. Fig. 7 is a perspective view of a flattened needle with a needle handle. Fig. 8 is an enlarged schematic view at a of fig. 7. Fig. 9 is an enlarged schematic view at B of fig. 7. Detailed Description Referring to fig. 5-9, a punch needle for removing holes Bian Maoci comprises a needle handle 1 and a needle head 2 formed on the end of the needle handle 1, wherein the needle head 2 is formed with punched holes on a polymer material or a plastic film material, and is characterized in that the needle head 2 is provided with a arched extension part 21, and the extension part 21 is surrounded by the edge of the needle head 2. The utility model has the beneficial effects that: the arch structure used in the utility model can solve the problem of burrs when punching, the material is firstly contacted to generate pre-stress, and then the extension part 21 continuously punches the material, so that a shearing surface with a raised smooth surface is obtained.
