12系列无轨外振预应力砼空心板挤压成型机,由于其不需要设置专门的导轨台座,场地利用率高,结构简单,维修操作方便,工效高,劳动强度低等优点,是目前比较受欢迎的一种挤压机,但也存在一些不足。现结合挤压成型预应力空心板产生的通病,谈谈其改进,以提高空心板的质量及挤压机的使用寿命,从而提高企业经济效益。一、对边墙板的改进由于原边墙板材质是铸铁的,硬度不高易磨损,尤其是中部成形腔易磨损成凹状,使空
12 series of trackless external vibration pre-stressed concrete hollow board extrusion machine, because it does not need to set a special guide rail pedestal, high site utilization, simple structure, easy maintenance and operation, high efficiency, low labor intensity, is currently relatively A welcome extruder, but there are also some deficiencies. Combining the common problems caused by the extrusion of pre-stressed hollow slabs, we will talk about its improvement to improve the quality of the hollow slabs and the service life of the extruders, thereby improving the economic benefits of the company. First, the improvement of the side wall plate As the material of the original side wall plate is cast iron, the hardness is not high and easy to wear, especially the middle forming cavity is easy to wear into a concave shape, making the air
