目前,生产预应力钢筋砼圆孔楼板,无论是室内钢模机组流水工艺,还是室外台座拉模工艺,用管芯振动成型生产占有一定的比重。管芯振动有结构紧凑,噪声较低,振动时间短,振动力前后均匀,成型的圆孔板棱角挺括、无蜂窝露筋、砼的密实度高等优点;它的主要不足之处是管芯内零件较多,且在制造工艺上有一定技术要求。但就我国目前构件行业制造和修理水平均能达到所需技术要求。管芯内振零件结构大体由轴支承、振子、多根连接在一条轴线上的轴及联轴器四种部件组成。除支承部位的滚动轴承按一定时间寿命需要更换外,最容易出现问题的是各轴之间的
At present, the production of pre-stressed reinforced concrete circular hole floor, whether it is the internal steel mold flow process, or the outdoor pedestal pull mold process, with the core vibration molding production has a certain proportion. The vibration of the die has a compact structure, low noise, short vibration time, uniform vibration force before and after, the advantages of the formed round hole plate corners, no honeycomb ribs, high density of ramming, etc.; its main deficiency is within the die. There are many parts and there are certain technical requirements in the manufacturing process. However, China’s current component industry manufacturing and repair of water can reach the required technical requirements. The structure of the internal vibration part of the die is generally composed of four components: shaft support, vibrator, multiple shafts connected to one axis, and coupling. In addition to bearing parts of the rolling bearings need to be replaced by a certain period of time, the most prone to problems is between the axes
