对R=(0.6～3.5)t的铰链式弯曲件怎样进行预弯,是关系到铰链卷圓质量和生产效率的一个重要问题。通常,卷圆预弯都按排在落料后进行,其方法在各种模具设计手册中都有介绍。
How to pre-bend a hinged flexure with R = (0.6-3.5) t is an important issue that relates to the quality of the hinge roll and the production efficiency. In general, the pre-bending of the rolls is carried out after blanking, and the method is described in various mold design manuals.
