我厂A123Б自动冷镦机,原为两次冲压成形的自动冷镦机,但根据我厂生产钢球和滚子的特点,只要一次冲压成形就可以了。 在无产阶级文化大革命中,我厂五连配件车间的广大革命职工提出要改革这台从苏修进口的老机器,在厂革委会的正确领导下,成立了连队“三结合”技术革新反修战斗队,只用了24小时的时间,就安装试车成功。这次改革后,生产效率提高了一倍以上,模具寿命比改革前提高20％。 目前尚还存在由于模具寿命较低,而且调整时间较长,故生产效率提高得不快。 改革后的结构特点是将原机器压料用传动机构中l:2的伞齿轮改为1:1的伞齿轮（见照片）。
Our factory A123Б automatic cold heading machine, the original two forging automatic cold heading machine, but according to the characteristics of steel balls and rollers I plant, as long as a stamping on it. In the Great Proletarian Cultural Revolution, the vast revolutionary workers in our factory, Wu Lian Parts Factory, proposed to reform this old machine imported from the Soviet Union. Under the correct leadership of the Plant Revolutionary Committee, a “triple combination” of technological innovations Repair the fighting team, only spent 24 hours on the installation test success. After this reform, the production efficiency has more than doubled, and the mold life is increased by 20% than before the reform. At present there are still due to lower mold life, but also to adjust the longer, so the production efficiency is not upset. The structural reform was to change the l: 2 bevel gear in the transmission mechanism of the original machine to a 1: 1 bevel gear (see photo).
