Development and commissioning of a cross-cutting site for forgings from special steel and alloys, built into a radial forging technological line

A technological section for transverse cutting of forgings produced on a radial forging machine SKK-14 from the Austrian company GFM has been developed, which has no analogues in the composition of the equipment, its layout and design. A new design of a valve ejector for forgings is proposed, the distinctive feature of which is its compact integration into the existing roller conveyor of a radial forging machine, as well as counter-directional rotation of the valve levers. To reduce the cutting force and heating costs, it is proposed to heat or preheat only part of the length of the forging at the place of its cutting using a specially designed induction heater. Taking into account the peculiarities of the hydraulic system of the P-6332 press and the requirements for cutting conditions on shears with parallel knives, an original design of a die for cutting forgings was developed, the distinctive features of which are the perception of axial cutting forces by the die columns during cutting, as well as the synchronization of the clamping and cutting mechanisms. Taking into account the execution of forgings using a P6332 hydraulic press with a developed upper cutting stamp, a special compact swinging drive roller table with a pressure roller has been developed, the swing axis of which is aligned with the axis of the roller table drive roller and is offset relative to the roller table center of gravity, ensuring the roller table returns to its previous position after tilting. To enable the movement of measured forgings and their storage, designs of a transport roller table, a lever ejector and storage pockets have been developed.
