摘要
在分析现有套管座和承力索座运用状况基础上,从结构型式、集成组合、维护性能等方面,对产品的结构、材料、工艺及制造模具等进行深入研究,研发了新型组合式承力索座。其主要特点是采用组合式结构、铰链抱箍连接和锻造生产工艺,大幅减少了零件和紧固件数量,避免了铸造工艺存在的缺陷,并随着材料和制造工艺的改进,进一步提高了产品的综合性能。
With analysis of service condition of bracket for tube and messenger wire support clamp, we developed new combined type messenger wire support clamp after intensive studied construction, material, process, molds and other aspects from structural style, integration, and maintain performance. Its main characteristics are section construction, hinge-hoop connection, and forging manufacturing technic, which reduced amount of fittings and fasteners a lot, and protect the products from shrinkage porosity, slag inclusion, air hole and other defects may exist during casting process. With improvement of material and manufacture process, comprehensive performance of fittings is improved.
