Abstract

PURPOSE:To regulate weight increase at a ram head by changing oil pressure according to weight of an attachment fixed to a ram and changing relative weight of two dead weights by oil pressure. CONSTITUTION:A limit switch 21 is selected according to the type of attachment to be fixed at the head of attachment to be fixed at the head of a ram 1. A motor 14 is driven to rotate pressure reducing values 22 and 23 and change oil pressure of a cylinder 33. The change ratio is set by the relation between a limit switch 2 and a dog 20. A dead weight 31 is pressed by the change of oil pressure in the cylinder 33 to change its relation with a dead weight 32. By this, weight of the dead weight 31 can be changed according to weight of attachments and weight increase at a ram head can be automatically regulated.
