1、Forging equipment.
Should be based on the different quality of forgings, the appropriate choice of template forging hammer tonnage, forging before the hammer head and hammer drill should be preheated.
2、Blank preparation.
Blanks should be cold sawed when undercutting, according to the different requirements of various types of carbide die toolings, the carbide segregation grade should be considered separately when selecting raw materials, and the appropriate forging process should be adopted, generally every upsetting three times can improve 1-1.5 grade.
3、Billet heating.
In the heating should be carried out slowly, to prevent acute heating, so as not to produce overburning phenomenon. When heating, strictly control the upper limit temperature, if found over-burning should be carried out in the furnace to cool down after forging.
4. Forging of billet.
When forging, first of all, lightly hit, remove the oxide skin in the forging process requirements, upsetting the billet must be placed correctly, so as not to make the billet was hit and run injury.
5, forging cooling.
Forging forming billet, should be placed in the lime box or sand pit, preferably placed in the 400-600 ° C insulation furnace for insulation, so that it is slowly cooled.
