圆柱形较长零件经淬火之后往往产生弯曲变形,为了校正需先测量弯曲度再校直,有时要反复几次才能达到校直目的。对于笨重的工件搬过来校直,搬过去检查,劳动强度很大。尤其是需要热校直的工件,一是搬运时烫手,二是往返搬运耽搁时间,工件温度降低就无法校直了。我们制做了一组能升降滑动的校直架(见图1),经一年的实践证明,大大减轻了校直和检查时的劳动强度, Cylindrical long parts are often quenched after bending deformation, in order to calibrate the need to measure the curvature and then straighten, sometimes several times to achieve the purpose of straightening. For unwieldy workpieces moved straight, move over to check, labor-intensive. In particular, the need for hot straightening of the workpiece, first, when handling hot, and second, the delay of moving from time to time, the workpiece can not be straightened to reduce the temperature. We made a series of straightening can stand glide (see Figure 1), after a year of practice has proved that greatly reduce the straightening and inspection of labor intensity,
