摘要
类椭圆变压器在工作中因考虑其散热性,箱壁采用波纹的方式以增大散热面积,而箱壁波纹的制作是变压器制作任务量最大的部分。四波压模的设计不但提高了波纹的生产效率,同时减少了单波双边修边的材料、人工的浪费,减轻了波纹组对劳动强度,为后期的水压试验也提供了结构保障。考虑模具长期高压作业产生的磨损、变形及波纹尺寸超差,对激光沉淀焊接及激光熔覆等新技术在模具修复中的应用进行了探讨研究。
Considering the heat dissipating of the walls,the ripple was usually adopted,which increased the cooling area and meanwhile was the largest task during the substation manufacturing. Four-side compression die not only increased the production efficiency but also saved the material and manpower comparing the one-side,which can reduce labor intensity of corrugation work group and provide structural assurances for later hydrostatic testing. Considering the abrasion, deformation and off-measurement of compression die,new technology,laser deposition welding and laser cladding,were researched and discussed for the repairing of compression die.
