Abstract

Изобретение относитс к обработке металлов давлением, в частности к универсально-штамповочным кулачковым многоползунным прессам-автоматам, и позвол ет повысить надежность и долговечность . Силова головка содержит основание 1, на котором смонтирован приводной вал 3 с закрепленным на нем рабочим кулачком 8, взаимодействующим с роликом 7 ползуна 8, На основании закреплены направл ющие планки дл ползуна 6. соединенного С-об- разной т гой 12 с составным двуплечим рычагом 11 механизма возврата ползуна. Рычаг 11 на оси 5 установлен на основании Iи его один конец снабжен роликом 10, контактирующим с возвратным кулачком 9, закрепленным на его приводном валу 3. Т га 12 расположена между кулачками 8 и 9. При вращении приводного вала рабочий кулачок 8 давит через ролик 7 на ползун 6 Происходит рабочий ход. При дальнейшем вращении приводного вала возвратный кулачок 9 давит на ролик Юдвуплечего рычр а IIи через т гу 12 возвратное усилие передаетс на ползун 6. 2 ил. The invention relates to the processing of metals by pressure, in particular to universal stamping cam multi-slide automatic presses, and makes it possible to increase reliability and durability. The power head contains a base 1 on which a drive shaft 3 is mounted with a working cam 8 fixed on it interacting with the roller 7 of the slide 8. On the base there are fixed guide bars for the slide 6 connected by a C-arm 12 with a composite two-arm lever 11 slide return mechanism. The lever 11 on the axis 5 is mounted on the base I and its one end is provided with a roller 10 in contact with a return cam 9 mounted on its drive shaft 3. T he 12 is located between the cams 8 and 9. When the drive shaft rotates, the working cam 8 presses through the roller 7 on the slider 6 There is a working stroke. With further rotation of the drive shaft, the return cam 9 presses on the roller of the Hunting shoulder lever II and, through the tu 12, the return force is transferred to the slider 6. 2 Il.
