1. Forging equipment: According to the different weights of the forgings, the tonnage of the die tools forging hammer should be appropriately selected, and the hammer head and hammer drill should be preheated before forging.
2. The preparation of the blank: cold sawing is appropriate when blanking the blank. According to the different requirements of various powder metallurgy molds, the carbide segregation level should be considered when selecting raw materials, and the appropriate forging process should be used. Generally, the increase can be increased every three times of upsetting. 1-1.5 level.
3. The heating of the blank: the heating should be carried out slowly to prevent rapid heating to avoid over-burning. When heating, strictly control the upper limit temperature. If overburning is found, the temperature should be lowered in the furnace before forging. When multiple pieces are heated, there must be a gap between the pieces, and they must be turned frequently during the heating process.
