Abstract:

Heavy load and increasing speed is significant to railway lorry, which requires coupler yoke be forged. Forging technique of coupler yoke is difficult because the part has complex shape and bulky volume. The whole forging processes of technical analysis, process confirmation and modification for coupler yoke were introduced. Different forging processes were compared and the reasonable forging technology was presented. This is applied to 17 and 16 types of coupler yokes production successfully.
