    齿条的加工方法

    来源:http://www.jnzkjx.cn/ 日期:2020-06-09 发布人:kaizejixie
      对付齿条的高硬度和高精度停止加工,特别是针对付齿条资料的热处置、齿形加工和堆焊铜层,该当只管即便对齿条的齿形停止两次的热处置和两次切割。  
    To deal with the high hardness and high precision of the rack, especially for the heat treatment, tooth shape processing and surfacing copper layer of the accessory rack data, it is necessary to stop twice heat treatment and twice cutting of the rack tooth shape.
    次的热处置主如果赞助齿条的资料打消内应力,紧接着便是停止次的齿形切割,在齿形切割的时刻该当预留出1-2毫米的余量;
    If the first heat treatment owner supports the rack data to eliminate internal stress, then the first tooth cutting shall be stopped, and a margin of 1-2mm shall be reserved at the time of tooth cutting;
    第二次对齿形停止热处置主如果为了使得齿形到达硬度请求,紧接着会对齿条停止堆焊铜层的处置,待磨好外圆以后,该当停止第二次的切割,包管这一次的齿条和外圆的轴线像对应。 经由过程对齿条的两次热处置和两次的线切割的瓜代加工处置,能够使得齿条的料淬透性停止进一步的进步,使之到达响应的硬度请求,同时还能够或许包管齿形的精度
    For the second time, if the heat treatment for the tooth profile is stopped, in order to make the tooth profile reach the hardness request, the rack will be stopped to weld the copper layer immediately. After grinding the outer circle, the second cutting shall be stopped, and the axis image of the rack and the outer circle shall be guaranteed to correspond. Through two times of heat treatment and two times of wire cutting, the material hardenability of the rack can stop further progress and reach the hardness request of the response, and at the same time, it can guarantee the accuracy of the tooth shape
