Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic model engraving cutters, in particular to a plastic model engraving cutter. Background Art
[0002] Plastic model engraving knives are used in the production and modification of plastic models, figurines and other plastic toys. They have fine blades and are mainly used to engrave precise, detailed and smooth lines on the model in order to depict the desired line groove effect. Based on the user needs for high-quality model production, model engraving knives are different from industrial engraving knives. They need to have fine engraving requirements, and they also need to form smooth, burr-free and residue-free high-quality lines and line grooves during and after engraving. Due to its special tool production, engraving knives are often used in the production and modification of Gundam model toys, and are welcomed by many DIY model toy enthusiasts at home and abroad. Common model toy companies such as Japan's Bandai Company (BANDAI), Japan's Hasegawa HASEGAWA, Tamiya TAMIYA, and domestic companies such as NUKE MATRIX are all well-known DIY model toy manufacturers in the market.
[0003] Since DIY engraving models belong to the new market, domestic players generally use model engraving knives imported from Japan, most of which are made of tungsten steel with an integral handle and blade, that is, knives made of one-piece materials, which are expensive. At present, there is a lack of relevant manufacturing technology for this type of plastic model engraving knives in China. Since the part of the entire knife that the user grasps with his hand is the handle, and only the blade in the blade head plays a cutting role, at least the handle does not need to use expensive tungsten steel (hard alloy). Utility Model Content
[0004] The utility model provides a plastic model scoring cutter, aiming to solve the problem of high cutter cost due to the integrated cutter in the existing plastic model scoring cutter.
[0005] According to an embodiment of the present application, a plastic model engraving tool is provided, comprising a blade body and a handle, wherein the blade body and the handle are connected; the blade body comprises a blade head and a blade, wherein the bottom of the blade head is connected to the blade, and the side of the blade head is connected to the handle, and the blade head and the blade are made of different materials; at least one of the blade head and the handle is made of steel or powder metallurgy.
[0006] Preferably, the cutter head is fixed to the cutting edge by welding, and the cutting edge is a cutting edge made of superhard material.
[0007] Preferably, the knife handle is integrally connected to the knife head, and the knife handle and the knife head are made of the same material.
[0008] Preferably, one side of the blade is connected to the blade head, and an adjacent side of the blade is connected to the handle. The blade is flush with the side of the handle at one end close to the handle, and the blade is fixedly connected to the handle.
[0009] Preferably, the cutter head is glued and fixed to the blade.
[0010] Preferably, the length of the knife handle is between 40 mm and 120 mm; the width of the knife handle is between 5 mm and 10 mm.
[0011] Preferably, the cross section of the handle is any one of circular, rectangular or waist drum-shaped.
[0012] Preferably, the blade is a polycrystalline diamond blade, a cubic boron nitride blade, a polycrystalline cubic boron nitride blade and a combination of one or more of an artificial synthetic diamond blade.
[0013] Preferably, the blade is away from one side of the blade head and forms an angle with the straight line direction in which the blade head extends.
[0014] Preferably, the knife head and / or the knife handle are made of carbon steel or stainless steel.
[0015] Compared with the prior art, the plastic model engraving tool provided by the utility model has the following beneficial effects:
[0016] 1. By using steel or powder metallurgy materials for the cutter head and handle, and different materials for the blade and the cutter head, the cutter of the present invention can use low-cost traditional steel or powder metallurgy materials except for the blade, thus reducing the cost impact of the high-cost blade material on the overall cutter, effectively reducing the cost of cutter materials, and facilitating the introduction of lower-priced cutters on the market, lowering the entry threshold for players, and facilitating the promotion of DIY toy models among the general public. At the same time, compared with the current brittle and hard tungsten steel overall cutters, steel and powder metallurgy materials can make the handle and cutter head of the cutter of the present invention less likely to break when accidentally dropped or impacted.
[0017] 2. The blade is made of super-hard material, which makes full use of the advantages of ultra-high hardness material, low affinity with plastic resin, easy flow of chips, and good cutting surface quality in the process of cutting and engraving plastic (plastic) models, greatly improving the cutting quality and the efficiency of users in making and modifying models. In particular, the current artificial cultivation of diamond technology is becoming more and more mature, the production cost of artificial synthetic diamond (CVD) has dropped significantly, and the material price has met the requirements of commercial production, so that this product's engraving knife can further reduce production costs, and transform the original status of engraving knives that rely on tungsten steel blades into diamond blades, which is conducive to realizing low-cost domestic independent production and sales of plastic model engraving tools and reducing the dependence on imports of engraving knife products.

The blade head 11 and the blade 12 are made of different materials, that is, the blade head 11 and the blade 12 are fixedly connected using two different materials, and the material of the blade head 11 will not affect the cutting effect of the blade 12.
[0030] At least one of the blade head 11 and the blade handle 2 is made of steel or powder metallurgy, and the blade 12 is made of superhard material.
[0031] It can be understood that steel is a common iron-carbon compound material in the prior art, such as 45# carbon steel, stainless steel (austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, austenitic-ferritic stainless steel); powder metallurgy materials are materials in the prior art that grind various materials into powders, mix them in different proportions, and then sinter them into shapes, such as metal ceramics. In the current market, compared with the higher price of tungsten steel, the use of powder metallurgy materials can reduce the material cost of products by about 60%; and the use of the above-mentioned steel, such as stainless steel, can further reduce the material cost of products by about 100% compared with tungsten steel, which has a very considerable cost reduction effect.
[0032] It can be understood that the blade 12 is made of superhard material blade, specifically a combination of one or more of polycrystalline diamond (PCD) blade, cubic boron nitride (CBN) blade, polycrystalline cubic boron nitride (PCBN) blade and artificial synthetic diamond (CVD) blade. A single material such as polycrystalline diamond (PCD) blade is integrally welded and fixed at one end of the blade body 1, so that the entire scoring tool has a better scoring effect.
