Abstract

FIELD: punching presses. SUBSTANCE: press contains clamp and twin hydraulic cylinder on whose rod punch is secured. Clamp is fitted with stop whose planes directed to rail are made at definite angle. Hydraulic cylinder body is received by central bore of clamp on one side; die with calibrated orifice is received on other side. Received by vertical bore of clamp is support fixing the coordinate of axis of hole to be punched from head of rail. Punch is made in form of ring with relief angle and hock angle; circular line of cutting is divided into "n" cutting edges relieved by lateral surfaces. EFFECT: enhanced reliability. 2 cl, 1 dwg

Изобретение относится к устройствам для пробивки отверстий, в частности, в рельсах. Пресс для пробивки отверстий содержит скобу и сдвоенный гидроцилиндр, на штоке которого закреплен пуансон, скоба снабжена упором, плоскости которого, обращенные к рельсу, выполнены под определенными углами. В центральных расточках скобы с одной стороны размещен корпус гидроцилиндра, с другой стороны - подводимая матрица с калиброванным отверстием. В вертикальной расточке скобы размещена подводимая опора, фиксирующая координату оси пробиваемого отверстия от головки рельса. Пуансон выполнен в виде кольца с передним и задним углами резания, а кольцевая линия резания разделена на n-е количество режущих кромок, затыловaнных по боковым поверхностям.The invention relates to devices for punching holes, in particular in rails. The press for punching holes contains a bracket and a double hydraulic cylinder, on the rod of which a punch is fixed, the bracket is equipped with a stop, the planes of which facing the rail are made at certain angles. In the central bore of the bracket, on one side there is a hydraulic cylinder body, on the other hand, a feed matrix with a calibrated hole. A vertical support is placed in the vertical bore of the bracket, fixing the coordinate of the axis of the punched hole from the rail head. The punch is made in the form of a ring with front and rear cutting angles, and the annular cutting line is divided into the nth number of cutting edges, backed along the side surfaces.
