【産業上の利用分野】この発明は冷温間鍛造加工を行う

潤滑剤を介在させることが行われる。2. Description of the Related Art Generally, when a forging material and a metal mold come into direct contact with each other during forging, seizure occurs there, which makes it impossible to mold the product satisfactorily. A lubricant is interposed between the material to be forged and the mold.

流し掛けるといった方法が採用されている。As a method of lubrication at that time, conventionally, a method of forming an oxalate film or a zinc phosphate film on the surface of the material to be forged, or pouring an emulsion liquid in which graphite is dispersed in water onto the surface of the mold is poured. Has been adopted.
【０００４】しかしながら従来の潤滑処理方法の場合、
充分な潤滑性能が得られず、また特に温間鍛造の場合、
適当な潤滑剤及びその処理方法が見当らないというのが
実情である。However, in the case of the conventional lubrication method,
Insufficient lubrication performance is obtained, and especially in the case of warm forging,
The reality is that no suitable lubricant and its treatment method are found.

用する潤滑剤が問題となるのである。If this is done cold during the forging process, a product with relatively good dimensional accuracy and good skin can be obtained, but the deformation resistance of the material is large, so it is difficult to process it to a certain extent. Therefore, in such a case, the temperature of 400 to
Forging is performed in a warm region of about 800 ° C., but the lubricant used at that time poses a problem.

うといった問題があった。[0006] That is, when machining is performed at such a high temperature, there is a problem that the conventional lubricant causes remarkable oxidative deterioration and there is a risk of ignition. In the case of a lubricant or its treatment method, the lubricant does not adhere firmly to the forged material or the surface of the mold, so during processing, the die and the forged material rub strongly against each other in the machined part of the forged material, If this happens, the lubricant of the same part will be easily removed, and as a result, the forged material will be forcibly deformed without the lubricant interposed between the die and the processed part of the material to be forged. Then, there was a problem that seizure would occur there.

5 to 30% by weight of one or more of iO 3 , Na 2 SiO 3 as a main component, and molybdenum disulfide and one or two of graphite are respectively molybdenum disulfide: 3 to 20% by weight, graphite An aqueous solution containing 1 to 10% by weight is uniformly applied to the surface of the material to be forged by a dipping method or the like, and then dried to support the inorganic salt and the inorganic salt on the surface of the material to be forged. To form a lubricating coating made of molybdenum sulfide and / or graphite.

れら無機塩とこれに担持された二硫化モリブデン，黒鉛
の粒子からなる潤滑被膜は優れた潤滑性能を示す。When the lubricating treatment is performed according to the present invention, a uniform and strong lubricating coating is formed on the surface of the material to be forged. When the lubricating coating was examined in detail, a film of the above-mentioned inorganic salt was uniformly formed over the entire treated surface of the material to be forged and firmly adhered to the surface of the material to be forged. It was confirmed that small particles of molybdenum disulfide and graphite were strongly supported. Thus, a lubricating coating consisting of these inorganic salts and molybdenum disulfide and graphite particles supported on them exhibits excellent lubricating performance.

ば手で拭う程度でも容易に表面からとれてしまう。When only the above-mentioned inorganic salt film is formed on the surface of the material to be forged, the inorganic salt has a certain effect of preventing seizure, but this one has a high friction coefficient and cannot perform a sufficient lubricating action. On the other hand, molybdenum disulfide and graphite as solid lubricants show good lubricity based on their cleavability, but they have weak adhesion to the surface of the mold and the material to be forged. It gets rid of.

能を発揮する。However, the lubricating coating formed according to the present invention has the features of both the strong fixing ability of the inorganic salt film and the good lubricating performance of the solid lubricant.
Due to their synergistic effect, excellent lubrication performance is exhibited during forging.

まで良好に潤滑作用を行う。For example, as described above, the lubricant easily peels off in the deformed portion of the material during the forging process, and seizure occurs there. However, the lubricating coating according to the present invention has a deformed portion of the material. In the above, the material does not easily peel off from the surface of the material, and in addition, it follows the deformation of the material satisfactorily and continues to be interposed between the surface of the material to be forged and the die, and performs a satisfactory lubricating action until the completion of processing.

In addition, this lubricating film exhibits good lubricating performance without causing problems of oxidation deterioration and ignition even during warm forging. Needless to say, such a lubricating coating exhibits excellent lubricating performance even during cold forging.

For example, when BN is used as the solid lubricant, such BN is not well supported by the inorganic salt.

乾燥することにより潤滑被膜を形成する。In the present invention, the material to be forged is immersed in an aqueous solution containing these inorganic salt and solid lubricant, or the aqueous solution is applied to the surface of the material to be forged, and then the surface of the material to be forged is dried. This forms a lubricating coating.

うことができる。As the drying means, it is preferable to volatilize water as a solvent or a dispersion medium by the heat of the material to be forged itself, that is, latent heat. Specifically, the aqueous solution is at 80 ° C
While maintaining the above temperature and maintaining it in a stirring state, the forged material in the heated state is immersed in this aqueous solution and pulled up to volatilize the water adhering to the surface of the forged material and to perform drying. it can.

についても同様である。In the present invention, the inorganic salt is 5 to 30% by weight, and the solid lubricant molybdenum disulfide and graphite are 3 to 20% by weight and 1 to 10% by weight, respectively.
This is because if it is out of these ranges, a good lubricating film is not formed. Here, the weight% of the inorganic salt means (weight of inorganic salt / volume of water) × 100 (%). The same applies to the solid lubricant.

The evaluation of the lubricating coating at that time was performed by measuring the height of the molded spike piece. The results are shown in Table 1 and FIG.

It is considered that this inorganic salt stably supports small particles of MoS 2 , C.
