Abstract

1. Способ получения чистовых отверстий в листовых заготовках, по которому к заготовке прилагают усилия прижима, пробивают в ней предварительно отверстие и калибруют его инструментом для калибровки, отличающийся тем, что, с целью повышения точности отверстий за счет предотвращения искажения формы отверстий на кольцевых участках, лежащих у пересечения поверхности отверстия с плоскостями, перед пробивкой предварительного отверстия к заготовке со стороны, противоположной приложению усилий прижима, на участке, прилежащем к поверхности разделения при пробивке, выдавливают кольцевое углубление, после калибровки отверстия снимают усилия прижима, после этого вновь калибруют отверстие.2. Способ по п.1, отличающийся тем, что для повторной калибровки используют тот же инструмент.1. A method of obtaining finishing holes in sheet blanks, through which clamping forces are applied to the blank, punch a hole in it and calibrate it with a calibration tool, characterized in that, in order to improve the accuracy of the holes by preventing distortion of the shape of the holes on the ring sections lying at the intersection of the surface of the hole with the planes, before punching the preliminary hole to the workpiece on the side opposite to the application of pressing forces, in the area adjacent to the surface once Jelenia when punching, squeezing annular recess, after calibration holes remove clamping force, then re-calibrated otverstie.2. Method according to claim 1, characterized in that the same tool is used for recalibration.
