なうスエージングマシンには、加熱された材料を
所定径に転打するダイスが設けられている。(Prior Art) For example, a swaging machine that performs swaging of a material (bar) in the manufacturing process of tungsten wire or molybdenum wire is provided with a die that rolls the heated material into a predetermined diameter.

ている。 Traditionally, this die has a structure in which a chip made of a heat-resistant metal such as Stellite (Co-Cr-W alloy) is built up in the center of a base material made of metal. Attempts have been made to use dies equipped with tips made of cemented carbide, which have a long life and excellent machining ability.

ばめが一般的に採用されている。 Therefore, in this die, brazing or shrink fitting is generally employed as a method of fixing the cemented carbide chip to the base material.
（考案が解決しようとする課題）
しかしながら、このような超硬合金チツプを用
いたダイスには次に述べる問題がある。(Problems to be solved by the invention) However, the die using such a cemented carbide chip has the following problems.

が必要である。 Since swaging of high melting point metals involves applying an impact force to the material heated to a high temperature, the above-mentioned method has problems under such usage conditions. That is, in the case of brazing, there is a problem that the solder metal melts and deteriorates at high temperatures, so the fixation of the chip tends to loosen, and the molten solder metal scatters. In addition, in the case of shrink fit (press fit), a tightness margin that is strong enough to withstand high temperatures and impact is required, but when shrink fitting is performed to obtain this tightness margin, the base material is However, in order to press-fit the chip, special equipment (e.g. press-fitting equipment at high temperature) is required.

なかつた。 Therefore, with conventional tools, brazing, and press-fitting, it is not possible to hold the cemented carbide chips until they wear out and reach the end of their service life, resulting in the chips popping out or destroying the case. The performance of the cemented carbide chip could not be fully demonstrated.

In the figure, reference numeral 1 denotes a rectangular parallelepiped base material made of tool steel, for example, and a groove 2 having a rectangular cross section is formed in the upper center of the base material 1 between both sides of the base material 1. In the figure, reference numeral 3 denotes a rectangular chip made of cemented carbide, and this chip 3 is fitted into the center of the groove 2 of the base material 1. Portions of the chip 3 corresponding to both side surfaces 2a, 2a of the groove 2, respectively, correspond to both side surfaces 2a, 2a of the groove 2.
2a, and the portions of the chip 3 that correspond to both open ends of the groove 2 (excluding the surfaces 3a, 3a that contact both side surfaces of the groove). is a retaining surface 3 that slopes from the top surface to the bottom surface in a widening shape.

溶融することがない。 However, in this die, the fixing material 4,
When the fixing materials 4, 4 (metal molten material) built up in the groove 2 of the base material 1 when forming the base material 1 cool and contract,
Since the fixing materials 4, 4 and both side surfaces 2a, 2a of the groove 2 are fixed together, the fixing materials 4, 4 shrink on cooling on both sides of the groove 2 of the base material 1, as shown in FIG. is pulled toward the inside of the groove 2. Both side surfaces 2a, 2 of the groove portion 2 displaced inward
The tip 3 fitted in the groove 2 is firmly clamped and fixed from both sides, and at the same time both side surfaces of the groove 2 are brought into close contact with the contact surfaces 3a, 3a of the tip 3. Therefore, the chip 3 is fixed in the groove 2.
Further, as shown in FIG. 5, the fixing members 4, 4 provided in the groove portion 2 are combined and in contact with the retaining surfaces 3b, 3b formed on the tip 3 so as to be inclined toward the tip. Even if it tries to escape upward from the groove 2, it is blocked by the fixing members 4, 4. Note that since the retaining surfaces 3b of the chip 3 are positioned facing the open end of the groove 2 and combined with the fixing members 4, 4 made of metal padding, the retaining surfaces 3b of the chip 3 are
b, 3b do not need to be formed into sloped surfaces with high precision to match the mating side; in short, they only need to be sloped to prevent the chip 3 from coming off, so machining is easy. Further, the chip 3 has flat contact surfaces 3a, 3.
Since a is in contact with both side surfaces 2a, 2a of the groove portion 2 and is prevented from rotating, it does not rotate.
Therefore, the chip 3 can be firmly fixed to the base material 1. Therefore, even if a die is provided in a swaging machine and a bar of tungsten or molybdenum heated to a high temperature is rolled, the fixation of the chip 3 does not loosen and can be used satisfactorily. In addition, since the melting point of stellite is approximately 1300° C., the fixing materials 4, 4 do not melt.
本考案の熱間加工工具は前記の実施例に限定さ

金属で形成しても良い。 The hot working tool of the present invention is not limited to the above embodiments. The base material is not limited to tool steel, and may be made of other metals. The fixing material is not limited to stellite, but may be made of other metals, for example, may be made of the same type of metal as the base material.
また、チツプは母材の溝部内での回り止めを図

る形状であれば良い。 Further, in order to prevent the chip from rotating within the groove of the base material, at least one of the contact surfaces is made flat. It is easy to process the chip's retaining surface if it is a sloped surface, but it is not limited to this and may be a stepped surface or a surface with a recess.The key is to allow the fixing material to come into contact with the chip, and to prevent the chip from coming off in the groove. Any shape is acceptable as long as it prevents it from coming off.
