长春汽车锻造厂630～2500吨热模锻压力机的刹车带的制动臂,原用整体钢(CT5)带。由于它是整体的,所以不能作得太厚,太厚了即降低了包闸性能。如以2500吨锻压机的制动臂为例,其厚变为10毫米,经常断折,严重时,曾有日断三次的情况,对维修和生产极为不利。机动部门发挥敢干创新的革命精神,改为绞链式。由于绞链式具有良好的可叠性,故可加厚制动臂厚度,从而提高其强度。经长期考验,性能良好,并已在我厂获得推广。
Changchun Automobile Forge 630 ~ 2500 tons of hot forging press brake belt brake arm, the original steel (CT5) with. Because it is monolithic, it can not be made too thick or too thick to reduce the barrier performance. For example, 2500T forging press brake arm, for example, the thickness becomes 10 mm, often broken, in serious cases, there have been three times a day off, on the maintenance and production is extremely unfavorable. Maneuver department to play a revolutionary spirit of innovation, to hinge type. Due to the hinge type has a good stackability, it can be thicker brake arm thickness, thereby enhancing its strength. After long-term test, the performance is good, and has been promoted in our factory.
