をスクロール部（２）に成形する。As shown in Fig. 1, a scroll compressor consists of two scrolls (1) integrally equipped with a scroll part (2), a flange part (3), and a boss part (4), which are assembled in opposition to each other, and one of them is connected to the other. The conventional forging method for producing the scroll for a scroll compressor is shown in Fig. 2. As shown in Fig. 1, in the first step, the workpiece is hot forged to form a scroll processed part (2a
), a flange part (3a) and a boss part (4a) are formed into a pre-processed product (1a), and the flange part (3a) and boss part (4a) are formed in the same process. 5: P: As shown in Figure 2, the scroll processed part (2a) has almost the same volume as the scroll part (2) in the final form so that it can be finished in the next process. In the first step - [Pre-processed product (1a) shown in Figure 2 after being formed]
The scroll processed part (2a) is formed by the following second step.
is formed into the scroll part (2).

れる。In the second step, for example, in the case of aluminum alloy, the lower side and boss part (4a) of the pre-processed product (1a) shown in FIG. 2 heated to 2001:' are first knocked out with the lower mold (6). The upper punch (9) is fixed by force, and then the upper die (5) is used to restrain the outer periphery of the 7-rank part (3a) and the scroll processed part (2a), and the upper punch (9) is fixed with force.
), the material of the scroll processed part (mu) flows into the mold (io) of the upper punch (9), and the scroll part (2) is formed into the final shape by so-called backward extrusion forging. After the second step, the scroll for a scroll compressor shown in Figure 1 is formed by cutting the tip of the scroll portion (2) to make it flat.

難点がある。However, in the conventional closed forging method for scrolls for scroll compressors, the processing time is significantly shortened compared to the forming method in which cutting is performed from a round bar material or finish cutting is performed after forging. It takes time and effort to hot-forge the material into a pre-processed product having a scroll-processed part, a 7-rank part, and a boss part, and also requires a step of forming the scroll-processed part into a scroll part.
Two steps are required to form the scroll part and the 7-rank part, which has the disadvantage of requiring a long processing time and a large number of steps.
