LOW-WASTE PROCESS FOR MANUFACTURING A PRECISION STAMPING TOOL.

The All-Union Correspondence Institute of Mechanical Engineering is developing a process for producing tools for tube rolling mills by precision hot stamping. The use of precision hot stamping of tube-milling tools permitted an increase in labor output by a factor of 9 and during mechanical treatment by a factor of 2-3 and reduced metal consumption 2- to 3-fold. During manufacture of bolts by stamping, owing to the increase in impact and fatigue characteristics of the metal, steel OKhN2F was replaced with the cheaper 30KhGSA. The cost of the stamped parts declined by a factor of 2-3. The economic effect from introducing the new process amounts to about 90 thousand rubles per year.
