Abstract

Изобретение относитс к кузнечно-прессовому оборудованию, в частности к конструкции компенсаторов неравномерности нагружени штампов к прессу. Цель изобретени - повышение стойкости штампов и качества штампуемых деталей. При ходе ползуна вниз и его перекосе на соответствующий угол происходит перекос верхней и нижней половин штампа. При этом хвостовик 2 поворачиваетс на необходимый угол относительно подп тника 3 путем перекатывани шариков 6 между их сферическими поверхност ми и смещаетс с подп тником 3 в горизонтальной плоскости путем перекатывани шариков 8 относительно стола. Угловой поворот хвостовика 2, который опираетс на сферическую поверхность подп тника 3 через р д шариков 6, резко уменьшает момент, действующий на направл ющие элементы штампа. 2 ил.The invention relates to press-forging equipment, in particular, to the design of compensators for uneven loading of dies to a press. The purpose of the invention is to increase the durability of the dies and the quality of the stamped parts. During the course of the slide down and its bias to the corresponding angle, the upper and lower halves of the stamp skew. At the same time, the shank 2 is rotated to the required angle relative to the submount 3 by rolling the balls 6 between their spherical surfaces and is displaced with the submix 3 in the horizontal plane by rolling the balls 8 relative to the table. The angular rotation of the shank 2, which rests on the spherical surface of the bolster 3 through a row of balls 6, sharply reduces the moment acting on the guide elements of the stamp. 2 Il.

Claims

Claim

Compensator for uneven loading of the stamp to the press, containing a base plate with a hollow threaded shank and a thrust bearing inside it, spherical surfaces facing each other, a gasket mounted on the base plate, a row of rolling bodies placed on the last thrust bearing in the form of balls in the separator, mounted around the perimeter of the thrust bearing an elastic element, as well as an elastic ring installed between the base plate and the nut articulated with a threaded shank, characterized in that, in order to increase the resistance of the strain Pa and the quality of stamped parts, it is equipped with an additional row of rolling bodies in the form of balls in a separator installed between the spherical surfaces of the shank and the thrust bearing, and the ratio of the number of rolling bodies in a row. placed above the thrust bearing p _in , to the number of rolling elements in a row placed under the 5 thrust bearing p _n. determined by the ratio pi _{= 1 25} .
