冲裁件的毛刺高度一直是冲件精度的一项最主要的参数,也是作为判别模具刃口是否需要重新刃磨的唯一依据,因此,测量毛刺高度不仅可以正确衡量冲件的精度,而且还可以充分经济地利用模具,合理地提高模具的使用寿命。然而,在以往的冲压工作中,往往只能在计量室内采用结构复杂的仪器测量一些精度较高的的小冲件毛刺高度。在生产实践中,大多只是用卡尺或千分尺来直接测量,微小的毛刺被破坏,因而也就不能读出正确的结果。因此,在更多的情况下就只得采用手摸的方式,凭
Burr height of the burr blanking height has been a piece of the most important parameters, but also as a tool to determine whether the need to regrind the blade edge grinding only, so measuring the height of the burr can not only accurately measure the accuracy of the punch, but also The mold can be fully and economically used, and the service life of the mold can be reasonably raised. However, in the past stamping work, it was often only possible to measure some high-precision burr height with a complicated structure in the measuring room. In production practice, most of them are only measured directly by calipers or micrometers, tiny burrs are broken, and the correct result can not be read. Therefore, in more cases, we only have to use hand touch method, by virtue of
