Abstract: In a forming machine for head part of a long  length  product like a wrench, a long bolt and a tool, a driving belt  pully  (26) and a flywheel (2a) are fixed on both  sides  of  the  main  crank shaft (2) across the main  body  (1).  A  hammer  crank  hod  (2') connects a hammer (3) with the main crank shaft. The hammer slides in the length direction of the main body and  attatches  a  hammer dice up- and-down operating plate (3a), which ups and  downs  along the groove on the hammer. A connecting  part  (8)  formed  on  the lower  part of  the  operating  plate  (3a)  is  connected  to  a up-and-down cam. A hammer dice (4) made of three steps is fixed on the outer part of the operating plate.

Abstract: An inner steel plate layer in the hot  rolled  three  layered composite  plate  comprises  0.7-1.2  wt.%  carbon,  0.5-1.5  wt.% maganese, 0.5-2.0 wt.% chromium, less than  0.2  wt.%  phosphorus, less than 0.02 wt.% sulphur, the  residual  iron,  and  inevitable impurities. An outer steel layr  comprises  0.2-0.3  wt.%  carbon, 0.35-0.6  wt.%  manganese,  3.0-3.5  wt.%  nickel,  1.0-1.5   wt.% chromium, 0.15-0.3 wt.% molybdenum, 0.15-0.35 wt.%  silicon,  less than 0.03 wt.% phosphorus, less than 0.03  sulphur,  the  residual iron and inevitable impurities. The three layered composite  plate is composed of two outer layers  having  high  toughness  and  one inner layer having high strength. The  thicknesses  of  outer  and innter layer are 40-60 % and more than 10 %  respectively  of  the total.
