Title:
MACHINE PRESS AND KEEPING OF SHUT HEIGHT THEREOF CONSTANT
Document Type and Number:
Japanese Patent JPS5853398
Kind Code:
A
Abstract:
In order to achieve thermal stability of the uprights (18) of a press in relation to the connection arms between the drive assembly and the slide of the press, waste heat from lubricant circulated through the drive assembly is utilized to heat the uprights (18). The oil is circulated through the crankshaft and connection arm assembly in the crown (20) and then caused to flow through a thermal transfer device (296) mounted to each of the uprights and comprising a series of baffles (300) over and through which the oil flows under gravity to form a series of vertically spaced pools in good thermal contact with the uprights. By adjusting the baffle structure so that the oil flows downwardly at a higher or lower rate, the amount of thermal transfer can be adjusted to ensure that equal thermal growth of the uprights and connection arms occurs.
