我厂铸造车间有2坐5吨冲天炉,多年来一直用人力进行堵眼,操作很不安全。为改善操作条件。大炉工人搞成了一套气动堵眼机构。经几年的生产实践证明,安全可靠,操作灵活,大大减轻了炉前工人的劳动强度。一、工作原理该装置结构见图。其工作原理是:利用气缸中活塞的往复直线运动,通过与活塞杆连接的钢丝绳牵动槽轮13和轴4作正反方向元周运动,使固定在槽轮轴上的泥杆上的泥盘抬起或压下,完成堵眼操作。当进入气缸的压缩空气压力为5公斤/厘米~2时,泥盘给于泥头的总压力达200公斤,比用人力直接堵眼的力量大很多。
Casting plant I sit 2 tons 5 Cupola, over the years has been using human eye plugging, the operation is not safe. To improve the operating conditions. Large furnace workers into a pneumatic eye blocking mechanism. After several years of production practice has proved that safe, reliable, flexible operation, greatly reducing the labor intensity of the furnace. First, the working principle of the device structure shown in Figure. Its working principle is: the reciprocating linear motion of the piston in the cylinder is used to make the movement of positive and negative circumferential movement of the sheave 13 and the shaft 4 by means of the steel wire rope connected with the piston rod, so that the mud plate lifter fixed on the mud shaft of the sheave shaft Either up or down to complete the plugging operation. When the pressure of compressed air into the cylinder is 5 kg / cm ~ 2, the total pressure of mud plate to the mud head is up to 200 kg, which is much larger than the force of directly blocking the eye with manpower.
