Development and improvement of equipment for a radial forging technological line using the SKK-14 RKM

The article presents the results of a set of design developments carried out by LLC “Metal-lurgical Institute of Advanced Technologies” together with LLC SPE “METCHIV” and South Ural State University to equip the SKK-14 radial forging machine with heating, transportation, transverse cutting and other mechanization means, protected by six invention patents and three utility model patents. The article presents information on the use of the developed continuous electric furnaces with end task and delivery, end task and side delivery, as well as an induction heating unit (IHU), which allow heating and preheating of blanks in various temperature modes depending on the steel grade and alloy for subsequent deformation on the SKK-14 radial forging machine. A description of the developed mechanism for piece-by-piece feeding of blanks for heating in the IHU is given. Information is given on the development of two sections of rotary roller tables with stops connecting the receiving and output sides of the SKK-14 rotary rolling machine, the use of which allows to expand the variability of transport flows in the SKK-14 rotary rolling machine process line. The efficiency of using the developed stop-ejector on the transport roller table is shown, which allows to consistently perform two technological operations: stopping the profiles moved after forging and their subsequent transfer to the storage pockets, without interfering, if necessary, with the reverse flow of blanks from the continuous furnaces to the forging block. The organization of a parallel process flow for accommodating the developed transverse cutting section with a valve ejector of blanks, an inclined slide, an induction heater of local (local) heating, a standard hydraulic press with a developed special cut-ting die equipped with a pneumatic clamp and spring shock absorbers, a swinging drive roller table with a pressure roller, an additional transport roller table with a stationary stop and a ejector is described. The practical implementation of several process flow diagrams using the developed equipment is shown.
