摘　　要：通过市场调查,辊压齿产品主要用于矿石、基础建设碎石的粉碎,需求量大。辊压齿成品加工内容包括外圆柱面、球面、底面、球面与外圆柱面的过渡区等四个方面。传统加工工艺采用无心磨外圆、平面磨底面、多用磨球面、钳工在抛光机上手工修研球面与外圆柱的过渡区,四道工序均单人单机操作;尤其是多用磨球面和钳工修研过渡区,为了提高产量,采用旋转状态不停机装卸产品,容易出现绞伤、划伤等的安全事故。我们通过辊压齿成品加工工艺探讨和研究,对辊压齿成品加工工艺进行了改进,采用低成本的自动化加工方法,由原来的四道工序(无心磨、平面磨、多用磨、钳工)减少为三道工序(无心磨、平面磨、数控多用磨);操作方式由原来的单人单机操作改进为自动化装卸料,杜绝了绞伤、划伤等的安全事故的发生;实现了一人多机操作,单班产量由原来的500件提升为2000件;产品质量得到明显提高,并大大降低了加工成本。According to the market survey,rolling tooth products are mainly used for crushing of ore and infrastructure crushed stone,with large demand.The processing content of the finished product of roller pressing gear includes four aspects:cylindrical surface,spherical surface,bottom surface,transition zone between spherical surface and cylindrical surface.The traditional processing technology uses centerless grinding of outer circle,plane grinding of bottom surface,multi-purpose grinding of spherical surface,and manual grinding of transition area between spherical surface and outer cylinder by fitter on polishing machine.The four processes are all operated by single person.In particular,multi-purpose grinding spherical surface and fitter grinding transition area,in order to improve the output,use rotating state to load and unload products without stopping,which is easy to cause accidents such as stranding and scratching.Through the discussion and Research on the processing technology of the finished product of the roller pressing gear,we have improved the processing technology of the finished product of rolling teeth,adopting the low-cost automatic processing method,reducing the original four processes(centerless grinding,plane grinding,multi-purpose grinding,fitter)to three processes(centerless grinding,plane grinding,CNC multipurpose grinding);the operation mode is improved from the original single machine operation to automation Loading and unloading materials,put an end to the occurrence of safety accidents such as stranding and scratching,and realized the operation of one person with multiple machines,and the single shift output increased from 500 pieces to 1500 pieces;the product quality was significantly improved and the processing cost was greatly reduced.
