Description
本新型係涉及工具機領域，尤指可替換式刀頭之切削刀具結構之技術領域。The present invention relates to the field of machine tools, and more particularly to the technical field of cutting tool structures of replaceable cutter heads.
按，一般高速鋼刀具係由高速鋼材質所車製而成，由於高速鋼之硬度較低，在經過多次使用後該切削部容易產生損耗，故其使用壽命短。因此，業者為了延長刀具之使用壽命，會採用硬度高之鎢鋼材料來製造刀具，但由於鎢鋼之價格昂貴，若要整支刀具皆由鎢鋼製造，其成本相當高昂，且在其耗損後仍須將整支刀具拋棄，相當地浪費成本。According to the general high-speed steel tool, it is made of high-speed steel. Because of the low hardness of high-speed steel, the cutting part is prone to loss after repeated use, so its service life is short. Therefore, in order to extend the service life of the tool, the manufacturer will use high-hardness tungsten steel to manufacture the tool. However, because the price of tungsten steel is expensive, if the whole tool is made of tungsten steel, the cost is quite high, and the loss is high. After that, the entire tool must be discarded, which is quite costly.
請參閱圖4所示者，於是就有業者將一刀體92及一刀柄91所組成一習用替換式刀具9，其中該刀柄91的材質係為一般鋼材所製成，刀體92所設的一切削部921材質通常係由鎢鋼材料所製成。又該刀體92在其底部設該切削部921，而該刀體92之頂端中心設有一結合螺桿922，該結合螺桿922可供一刀柄91的一端所設的一結合螺孔911套入結合，而該結合螺孔911與該結合螺桿922於套接後，在利用螺紋鎖固結合方式，將該刀體92牢牢結合於該刀柄91上。Referring to the figure shown in FIG. 4, the manufacturer has a tool body 92 and a tool holder 91 to form a conventional replacement tool 9, wherein the material of the tool holder 91 is made of general steel, and the body 92 is provided. The material of a cutting portion 921 is usually made of a tungsten steel material. Further, the cutter body 92 is provided with the cutting portion 921 at the bottom thereof, and a center of the top end of the cutter body 92 is provided with a coupling screw 922. The coupling screw 922 can be inserted into a joint screw hole 911 provided at one end of a shank 91. After the coupling screw hole 911 and the coupling screw 922 are sleeved, the cutter body 92 is firmly coupled to the shank 91 by screwing and fastening.
然，上述習用替換式刀具9，因其刀柄91係使用一般鋼材，故其側向剛性仍嫌不足，於切削加工進給量大的情況下，容易有震刀現象而損壞鎢鋼刀片及工件的加工面，實有改善的空間。However, the conventional replacement tool 9 described above uses a general steel material for the shank 91, so that the lateral rigidity is still insufficient, and in the case of a large feed amount in the cutting process, the knives are easily damaged and the tungsten steel blade is damaged. The working surface of the workpiece has a real improvement.
再者，上述習用替換式刀具9係使用螺紋鎖固結合方式，無法達成較高的精度，導致該刀具9使用於加工機器時，在高速運轉下，容易引起該加工機器震動外，所加工於工件的加工面，容易產生刀痕，如此便無法提升工件加工面之精度。Furthermore, the conventional replacement tool 9 is a thread-locking combination method, and high precision cannot be achieved. When the tool 9 is used in a processing machine, it is easy to cause vibration of the processing machine under high-speed operation, and is processed in The machined surface of the workpiece is prone to tool marks, which makes it impossible to improve the precision of the machined surface.
鑒於上述習用刀具的問題點，故本新型創作人於是創作出本新型刀具結構，其最主要目的: 在於提供低成本的替換式刀頭之切削刀具結構；本新型的次要目的:在於提供高剛性、高精度的替換式刀頭之切削刀具結構。In view of the above problems of the conventional tool, the novel creator has created the new tool structure, and its main purpose is to provide a low-cost cutting tool structure for the replacement cutter head; the secondary purpose of the present invention is to provide high Rigid, high-precision cutting tool structure for replacement cutter heads.

上述該刀柄係設為鎢鋼材料所製成。The shank described above is made of a tungsten steel material.
上述該刀頭係由一刀座、複數個刀片所構成，且該複數個刀片得接設於該刀座上，而該刀座係由耐熱鋼所製成。The cutter head is composed of a cutter seat and a plurality of blades, and the plurality of blades are connected to the cutter seat, and the cutter seat is made of heat-resistant steel.
本新型替換式刀頭之切削刀具結構藉由上述技術手段，可以達成如下之功效: 1. 本新型切削刀具結構係運用熱漲冷縮的燒結原理，俾供該刀頭可安裝、拆卸於該刀柄，待該刀頭的使用壽命終了時，可拆換新的刀頭，而可節省刀柄的材料費用，進而製造出低成本的切削刀具。 2. 由於本新型切削刀具結構的刀柄，係使用鎢鋼材料所製成，故其側向剛性夠，可提升精度約至0.003mm的公差範圍，即使本新型切削刀具於大進給的切削加工的情況下，其加工精度，亦會有提升的效果。The cutting tool structure of the novel replacement cutter head can achieve the following effects by the above technical means: 1. The cutting tool structure of the present invention utilizes the sintering principle of heat expansion and contraction, and the cutter head can be installed and disassembled in the cutter head. The tool holder can be replaced with a new one when the end of the service life is completed, and the material cost of the tool holder can be saved, thereby manufacturing a low-cost cutting tool. 2. Since the shank of the cutting tool structure of the present invention is made of tungsten steel material, the lateral rigidity is sufficient, and the precision can be improved to a tolerance range of about 0.003 mm, even if the cutting tool of the present invention is cut at a large feed. In the case of processing, the processing accuracy will also have an improved effect.
