Description of the Related Art In order to improve the quality of a cast billet, a material for forging has been prepared by directly extruding prior to forging and removing surface defects as discards. At this time, improvement in quality by one-time plastic working is also being studied. In the case of passing through the indirect extrusion step, the surface of the casting billet is caught in the extruded material, so the surface of the casting billet is cut prior to the extrusion. Recently, in order to reduce the manufacturing cost, a casting / forging method for directly forging a cast billet without an extrusion step has been studied. In this casting / forging method, a preformed body close to a product shape is produced by casting, or a billet or the like is produced by semi-continuous casting, and the preformed body or billet (hereinafter, referred to as a cast material) is forged. Forging may be either cold forging or hot forging, but when a large product is obtained, hot forging is employed.

Therefore, prior to forging, it is necessary to remove the deteriorated surface layer of the cast material by cutting or the like. Therefore, an extra cutting step is required, and the advantages of the casting / forging method cannot be fully utilized. The present invention has been devised to solve such a problem. By improving the casting and forging dies, the need for cutting the surface of the casting material is eliminated, and the casting material can be directly forged. The purpose is to do.

る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The surface of a cast material such as a preformed body obtained by casting or a billet obtained by semi-continuous casting has a segregation layer caused by entrainment of foreign matter or gas, heat removal by a mold, and the like. There is a surface altered layer such as a chill layer. Various defects occur when the surface altered layer is involved in the material.In the present invention, however, the outer surface layer of the cast material parallel to the forging direction is allowed to escape to the clearance between the male mold and the female mold. Accordingly, the step of cutting and removing the surface altered layer of the cast material prior to forging is omitted. In forging using a conventional mold, as shown in FIG. 1, an extruded material 1 cut to a predetermined thickness is inserted between a male die 2 and a female die 3, and the male die 1 is pressed to a predetermined pressure or a predetermined height. Lower it for forging. At this time, there is a slight clearance between the outer surface 4 of the punch portion of the male mold 2 and the inner surface 5 of the female mold, and there is also a slight clearance between the outer surface 6 of the extruded material 1 and the female mold inner surface 5. Due to these clearances, the extruded material 1 is smoothly pushed into the female mold 3.

As shown in FIG. 5, a metal reservoir 7 having a gap d is provided between the outer surface 4 of the punch portion of the male die 2 and the inner surface 5 of the female die. Gap d
Is larger than the thickness of the surface altered layer 9 on the surface layer of the casting material, and is usually set to 2 mm or more. As the forging material 8, a cast material having a casting surface left without cutting the surface is used, and the cast material is sliced to a predetermined thickness and set in the female mold 3. When the male mold 2 is pushed into the female mold 3 containing the forging material 8, the forging material 8 is formed into a forged product 11 having a projection corresponding to the wrap portion 10 of the female mold 3. At this time, the deteriorated surface layer 9 around the forging material 8 enters the metal reservoir 7, and the forged product 11 having a height H is formed.
Protruding around. That is, the surface altered layer 9 is prevented from flowing due to friction with the female mold inner surface 5 at the time of forging, and remains in the vicinity of the metal reservoir 7 and the female mold inner surface 5 as it is. On the other hand, good metal flows into the wrap portion 10.

行き渡り、良好な品質の鍛造品１１となる。After the obtained forged product 11 is taken out of the mold, it is subjected to a predetermined heat treatment, and is finished to a predetermined size by machining. At this time, since the altered surface layer 9 is cut and removed, a forged product 11 free from defects due to the winding of the altered surface layer 9 is obtained. The post-forging cutting finish performed for dimensioning is also required by a conventional method using a cutting billet. However, in comparison with this conventional method, in the present invention, the surface cutting of the casting material as the forging material 8 becomes unnecessary, and the forged product 11 is manufactured without going through the extrusion step. In addition, since there is no winding of the surface altered layer 9,
The amount of cutting work for dimensionally finishing the forged product 11 can be reduced, and the yield is improved. The forging material 8 has a wrap 10
The height h is set to a value obtained by adding the height h for compensating the necessary amount of metal flowing into the product height to the product height H. This forging material 8
When forging is performed, a sufficient amount of meat is distributed to the lap portion 10 and the corners, and a forged product 11 of good quality is obtained.

A forged product 8 having the shape shown in FIG. A product is obtained by cutting off the surface altered layer 9 on the outer periphery of the forged product 8. The removal of the forged product 11 from the female mold 3 is facilitated by using the male mold 2 having the fringe portion 12 provided on the punch outer surface 4 as shown in FIG. That is, the convex fringe portion 12 provided on a part of the punch outer surface 4 that is in contact with the surface deteriorated layer 9 engages with the forged product 11 when the male die 2 is lifted from the female die 3 and engages with the male die 2. The forged product 11 in the fitted state is lifted from the female mold 3. Fringe part 1
2 can be formed over the entire periphery of the punch part outer surface 4 or partially, but it is more advantageous to provide it over the entire periphery in terms of mold production. The protrusion width x of the fringe portion 12 is 0.2 mm
The degree is preferred.

At this time, since the fringe portion 12 is located on the surface altered layer 9, even if it is deformed when knocked, it is cut and removed by subsequent machining. Therefore, the depression corresponding to the fringe portion 12 is formed in the surface altered layer 9.
However, there is no hindrance to the forged product 11 as a product.
