FIELD: process engineering.SUBSTANCE: invention relates to machining, particularly, to device intended for piercing meeting holes on opposite side walls of hollow parts with parallel vertical walls. Female die with working opening for removal of wastes is rigidly fixed at the housing. Male die is mounted to reciprocate. Male die displacement mechanism is composed of drive with manual control arranged at housing rod moving plate interacting with rack engaged via rod with male die. Said housing is provided with mirror mounted on holder to turn about horizontal and vertical axes. Note here that female die is shaped to part contour and allows part clamping.EFFECT: higher precision.2 cl, 2 dwg |
