我厂批量生产齿轮。由于缺乏专机,齿轮键槽(图1)过去一直是利用一台60吨冲床插制而成,质量既达不到要求,劳动强度又大。针对这个问题,我们利用了废弃的C6136床身和拖板,改装了一台二吨半的液压拉床,采用了高效的拉削工艺。 I plant mass production gear. Due to the lack of special plane, gear keyway (Figure 1) in the past has been the use of a 60-ton punch inserted, the quality of both meet the requirements, labor-intensive. In response to this problem, we used the abandoned C6136 bed and pallet, converted a two and a half tons of hydraulic broaching machine, using an efficient broaching process.
