Problems solved by technology

[0002] The existing forging heating and forging, edge trimming, finishing and other processing technology schemes are generally: manual lifting, feeding heating (coal heating furnace), manual feeding to the jaws of the pusher, and feeding the material to the press after heating. Long (or pier thickness), manual pre-forging, manual final forging, and then manually place the forging with flash on a mechanical or hydraulic press to complete trimming, punching, finishing and other processes, and then manually place it on the Controlling the cooling line, some forgings are complex forging processing, relying solely on inconsistent manual positioning and placement, resulting in forging folding, insufficient filling, and high scrap rate. The internal metallographic structure of the billet at 1240°C has embrittlement (overburning). The internal grain boundary of the overfired forging is oxidized to form a brittle shell, which seriously damages the connection between the grains and will break into pieces during forging. Seriously Affects the performance of forgings, and when the blank is lower than 1180 ℃, it will cause forging defects such as filling dissatisfaction, high production costs such as energy consumption, and 6 to 8 workers are required to complete the above operations, manual feeding, manual control, and labor intensity. The environment is poor and the production efficiency is low; the quality of forgings fluctuates greatly, and the mechanical properties of each part of the forging are uneven, which affects the internal strength and microstructure of the forging, and poses a great safety hazard
