根据现场工程地质条件,16吨模锻锤基础是座落在砂岩层上。这样大吨位锻锤基础直接建造在岩基上,在国内还不多见。为了合理地选择锤基础设计方案;较正确地估价在锻锤生产运行时厂房结构的动荷反应;以及确定和防止对振动反应比较敏感的铸工车间泥芯工部、金工车间精密机床和中央试验室精密仪表的影响,我们进行了一些调查研究,并对一些锻工车间进行了振动实测。结合工程的实际情况,又在现场进行了缓冲垫层的刚度系数、吸振效应和强度等各项试验,取得了一些数据,从而使锻锤基础的设计能够建立在一定的科学基础之上。为了交流经验,现将前一阶段的工作小结摘要介绍
According to the site engineering geological conditions, the foundation of the 16-ton die forging hammer is located on the sandstone layer. This large-tonnage forging hammer foundation is built directly on the rock foundation and is still rare in China. In order to rationally select the hammer design scheme, to accurately estimate the dynamic load response of the structure of the power plant during the production and operation of the forging hammer, and to determine and prevent the sensitive response to the vibration in the foundry workshop, the Mud Industry Department, the precision machining center and the central test With the influence of precision instruments in the room, we conducted some investigations and studies and measured the vibration of some forging workshops. Combined with the actual conditions of the project, various tests such as the stiffness coefficient, vibration absorption effect and strength of the cushion cushion were performed on site and some data were obtained, so that the design of the forging hammer foundation can be established on a certain scientific basis. In order to exchange experiences, the summary of the work in the previous stage is summarized.
