Abstract

1,180,106. Extruding; forging. O. BIGINELLI. 14 July, 1967 [12 May, 1967], No. 32499/67. Headings B3H and B3P. A tubular steel element having a closed end 1 3 , Fig. 4, is formed by deforming a steel block at 700-750‹ C. in a first die 3, Fig. 2, by a first ram 2 to form a blank which is further deformed without reheating using a second die 9 and ram 8. In one embodiment, the block (1) positioned at the bottom of the die 3 is widened to form the blank 1 2 by the ram 2 having a detachable contact head 5 1 of tunsten carbide or high-speed steel. The blank 1 2 is then deformed in the second die 9, having a bore diameter corresponding to the maximum diameter of the blank, by the ram 8 of the same diameter as the diameter 5 3 of the ram 2. Each die is provided with an extractor 4. In another embodiment, the initial blank is formed from a block (1), (Fig. 5, not shown), having a diameter equal to the bore diameter 31 of the die by a ram (2 1 ) which displaces part of the block into the smallest diameter (3 2 ) of the die.
