自由锻锤是目前中小型工厂的普遍而又是主要的锻造设备。用自由锻造制坯,生产效率低,劳动强度大,机加工余量大,浪费原材料。即便是过渡到胎模锻造后,虽有所改善,但效果也不显著,而且由于操作时上下搬动和翻转沉重的胎模,工人的劳动强度相应的有所增加。由于自由锻造存在着以上这些缺点,所以不适应我国目前工农业生产的跃进局面,有革新的必要。怎样运用毛主席的哲学思想,去解决客观世界中存在的问题,改造老设备,革新旧工艺,充分发挥现有设备的生产潜力,是一个相当重要的问题。 Free forging hammer is the universal and major forging equipment in small and medium-sized factories. Forging with free billet, low production efficiency, labor-intensive, machining allowance, waste of raw materials. Even after the transition to the tire forging, although the improvement, but the effect is not significant, but also due to the operation of moving up and down and flip heavy tire mold, the corresponding increase in the labor intensity of workers. Because of these shortcomings in free forging, they are not suitable for the current leap forward in industrial and agricultural production in our country and are necessary for innovation. How to use Chairman Mao’s philosophical thinking, to solve the problems in the objective world, to reform the old equipment, to reform the old technology, and to give full play to the potential of the existing equipment is a very important issue.
