Abstract

PURPOSE: To obtain the subject housing the steps thickness thereof is greater than the dimension of material by means of a relatively small output press by heating a cylinder of carbon steel and by squeezing it into the drag by means of the cope.
CONSTITUTION: A cylinder 11 of carbon steel such as rolled steel for weld-sturcture is prepared, its internal diameter is made approximately equal to that of outlet 1b of the housing 1. The drag 15 is composed of the base 15a and the die 15b, and the inner shape of the die is made approximate to the outer shape of the housing. Also the outer shape of the cope 12 is made approximate to the inner shape of the housing which consists of the outlet 1b, thick-walled steps 1c and a portion of the central part 1a. The cylinder 11 is heated up to 900°C and is put in the die 15b on the base 15a, the cope 12 is pressed down in the cylinder to obtain a product.
