The invention relates to a large-sized stainless steel nut, and in particular relates to a hot-forging molding process of the large-sized stainless steel nut. The hot-forging molding process comprises the following steps of: (1) preheating: preheating stainless steel raw materials in a high-...
Hot forging can be defined as “a metal shaping process in which a malleable metal part, known as a billet or workpiece, is worked to a predetermined shape by one or more processes such as hammering, upsetting, pressing and so forth where the workpiece is heated up to about 75% of its...
employ design optimization method in forging technological design process [1; 2] . In forging areas, the die design procedure is very often a trial-and-error process and a number of forging trials may be needed before reaching a satisfactory design ...
This paper illustrates about a shrink-fit design used to improve the die-service life in the hot forging process of a bevel gear. In this process, there are two-operation steps of forming, preform and finishing steps. The major problem was that the forging die in finishing step prematurely ...
After the hot forging process ends, parts must be cooled rapidly to "set" the metal in its new shape. Care must be taken in the cooling process, however, as cooling hot forged parts too quickly can result in warping. Additionally, the hot forging process produces little to n...
Method of forging precipitation hardening type stainless steel An improved method of forging a precipitation hardening type stainless steel. The method comprises the steps of soaking the precipitation hardening type stainless steel at a temperature of austenitizing range, cooling the steel to a temp.....

A hot-forging shaping process for a joint hinge comprises the following steps: (1) heating a blank to 1050~1150℃ by an intermediate frequency furnace; (2) upsetting the heated blank slightly by a pneumatic hammer to remove the oxide scale on the surface of the blank; (3) forming the un...
The life of dies depends on how well they were designed and made, including the thermochemical treatment and mechanical working, the sequence of steps in the thermal treatment and the forging process conditions (the tool and preform temperature, the charge material geometry, the process rate, the...
