摩擦压砖机是耐火材料厂制品成型的主要生产设备,也是制品成型工序中的薄弱环节。不仅劳动强度大,而且还由于无可靠的安全装置,操作者断手断臂的人身事故时有发生,成为生产中的老大难问题。我厂自1959年至1982年,共发生轻伤事故172起,断两指以上的重伤事故36起,给工人的健康安全造成严重的威胁。在总结现有摩擦压砖机安全装置的基础上,我们研制了电控气动安全装置。该装置结构简单,操作方便。经生产使用证明,性能稳定,动作 Friction brick pressing machine is refractory products molding factory production equipment, but also the product forming process of the weak links. Not only labor-intensive, but also due to no reliable safety device, the operator broke the arm of the personal accident has occurred, become a chronic problem in production. From 1959 to 1982, I suffered a total of 172 minor injuries and 36 serious injuries more than 2 fingers, posing a serious threat to the health and safety of workers. On the basis of summarizing the existing friction brick safety device, we have developed an electronically controlled pneumatic safety device. The device has the advantages of simple structure and convenient operation. The use of proof of production, stable performance, action
