法が広く採用されている。(Prior art) Electromechanical parts such as terminals and bolts/screws are made by applying pressure to rod-shaped or block-shaped metal materials using a tool to impart a forging effect to improve the mechanical properties of the material and at the same time to improve the mechanical properties of the material. It is manufactured by being molded into a shape. In particular, a header processing method is widely adopted in which the entire length or part of a metal material is compressed in the axial or radial direction to expand its diameter or width to form a head portion of a predetermined shape.

度を常に低く保持した状態で加工が行なわれる。Generally, the header processing method involves inserting and fixing a rod-shaped metal material 2 cut to a predetermined length into a die 1, which is a lower mold carved into a predetermined shape, as shown in Fig. 1. 2
As shown in the figure, a processing method in which the metal material 2 is pressurized and compressed in the axial direction with a punch 3 to fill the space in the die with the material at the upper end of the metal material 2 to form a head portion 4 of a predetermined shape. It is. During this processing and forming, in order to prevent the metal material from sticking to the mold surface, a diluted solution of water-soluble graphite, for example, was applied to the outer surface of the metal material as a T6 lubricant to keep the mold surface temperature low at all times. Processing is performed in this state.

金属素材として高強度合金やＮｉを多岳に含有した粘り
強さの大きい合金材を使用した場合に顕著となる。(Problem to be solved by the invention) However, in conventional spacing ladder processing, a large forming load is applied at room temperature to plastically deform the metal material to form the head part, which causes wear and tear on the mold. There is a problem that occurs frequently. This mold wear and the like becomes particularly noticeable when a high-strength alloy or a highly tenacious alloy containing a large amount of Ni is used as the metal material.

点もあった。In addition, despite the use of lubricant, the metal material partially seizes onto the mold surface and forms protrusions, and each time the molded product is subsequently pulled out of the die, the protrusions cause linear marks on the surface of the molded product. There was also the problem that this caused the formation of particles, degrading the quality of the product.

率を大幅に低下させる原因ともなっていた。Furthermore, every time the mold seizes or is damaged, it is necessary to stop the header processing machine, remove the mold, and polish it. This work requires a great deal of labor and is a major hindrance in the header processing process, and at the same time causes a significant drop in production efficiency of molded products.

準で２μｍ以上に設定したことを特徴とする。(Means for Solving the Problems) In order to achieve the above object, the header processing material according to the present invention is a header in which a head portion of a predetermined shape is formed by pressing the end of a metal material with a mold in the axial direction or radial direction. It is a metal material used for processing, and is characterized in that the surface roughness of the metal material is set to 2 μm or more based on the maximum height (Rmax) standard aX.

発明者が両者の関係を微細に研究したところ、素材の表
面粗さと金型寿命との間に強度の相関関係があることが
判明した。In the past, sufficient consideration had not been given to the effect that the surface quality of the header processing material had on the life of the mold. However, when the present inventor conducted a detailed study on the relationship between the two, it was found that there is a strength correlation between the surface roughness of the material and the life of the mold.

以下本発明の限定理由を述べる。The reasons for the limitations of the present invention will be described below.

作に供する方法、砥石粉によって金属素材表面にホーニ
ング加工を行う方法などがある。Methods for adjusting the surface roughness include immersing the metal material in a pickling bath to partially improve the surface roughness, subjecting the metal material to a drawing operation with an appropriate area reduction rate after pickling, and using a grinding wheel. There is a method of honing the surface of a metal material using powder.

材を連続的にヘッダー加工に供し、１１１の金型を交換
または再研摩することな（連続的に加工できる回数を測
定した。By the above method, the surface roughness of the metal material was adjusted and a material for header processing was obtained. Then, this header processing material was continuously subjected to header processing, and the number of times that the header processing could be performed continuously was measured without replacing or re-polishing the mold 111.
その結果、金属素材の表面粗さを最大高さ（Ｒｍａｘ）
基準で２μｍ以上に設定した場合に加ＩａＸ
１回数が大幅に増加し金型の保守交換回数が大幅に低減
されることが判明し、成形品の生産効率を大幅に向上さ
せることが可能となった。As a result, the surface roughness of the metal material is determined by the maximum height (Rmax).
It was found that when the standard was set to 2 μm or more, the number of IaX additions increased significantly, and the number of mold maintenance and replacement times was significantly reduced, making it possible to significantly improve the production efficiency of molded products. Ta.
一方、表面粗さを２μｍ未満に設定した場合は、金属素
材の金型表面への焼き付きが多く、金型の保守回数が増
大し、加工性、生産効率ともに低下してしまう。従って
表面粗さは、２μｍ以上に設定することが重要である。On the other hand, when the surface roughness is set to less than 2 μm, the metal material tends to stick to the surface of the mold, the number of times maintenance of the mold increases, and both workability and production efficiency decrease. Therefore, it is important to set the surface roughness to 2 μm or more.

Center line average roughness (R8) and ten point ax average roughness (R7) are JIS B-0601-198
This was measured based on 2.

It was determined that the life of the mold had ended when defects such as marks due to seizure appeared on the surface of the molded product.

運転も容易になる。As is clear from Table 1, the material for header processing according to this example has significantly improved formability compared to the conventional material for header processing that has a smooth surface. It becomes possible to dramatically increase the number of times that the mold can be processed continuously, and the production efficiency of molded products can be greatly improved. In particular, maintenance work such as mold repair and re-polishing is significantly reduced, making header processing equipment easier to operate.

型内表面とが完全に密着することが防止され、両表面間
に形成された空間に潤滑剤が常に保持され、両者の焼付
き現象が効果的に防止されるためと考えられる。The reason why formability is improved is that by setting the surface roughness of the metal material to 2 μm or more, complete contact between the metal material surface and the inner surface of the mold is prevented, and the formation between the two surfaces is prevented. This is thought to be because the lubricant is always kept in the space, effectively preventing the seizure phenomenon between the two.

と考えられる。On the other hand, the surface of the conventional metal material is finished very smoothly, so that the inner surface of the mold and the metal material tend to come into close contact, and the lubricant film is easily removed. Therefore, it is thought that the lubricating effect was not effectively exerted, causing seizure and shortening the life of the mold.

十点平均粗さ（Ｒ２）で１．５μＴｒＬ未満に設定した
場合は、連続ヘッダー加工回数は少なく、成形性の改善
効果は少ないことが実証されている。It has been demonstrated that when the ten-point average roughness (R2) is set to less than 1.5 μTrL, the number of continuous header processing is small and the effect of improving formability is small.

設定すると好ましい効果を得ることができる。Therefore, although it varies depending on the quality standard of the molded product, the surface roughness of the alloy material used in the example was determined by the maximum height (
Rmax) standard: 2.0 to 10.0ax μ tile center line average roughness (Ra): 0.20 to 1゜oμm
A preferable effect can be obtained by setting the ten-point average roughness (R2) in the range of 1.5 to 8.5 μm.
