摘要
液压支架油缸在设计中需要增大缸口外圆尺寸。分析了堆焊和焊圆环筒2种增加缸口尺寸的方法,针对2种方法在实施过程中存在的质量隐患,寻求一种既能增大缸口尺寸,又能消除质量隐患的增形方法。提出通过局部镦粗技术增形,利用锻件的优势来有效地解决这一问题,进而把局部镦粗技术推广应用到油缸其他零部件上。
In the design of hydraulic support cylinder,it is necessary to increase the outer circle size of cylinder mouth.Analyzed two methods of increasing the cylinder mouth size,namely,surfacing and welding circular cylinder.Aiming at the quality hidden dangers in the implementation of the two methods,seeks a method of increasing the cylinder mouth size and eliminating the quality hidden dangers.Proposed that the problem can be effectively solved by using the advantages of forgings through the local upsetting technology to increase the shape,and then the local upsetting technology can be extended to other parts of the oil cylinder.
