Abstract
PURPOSE: To save works such as of oxalating, pickling, etc. of base metals by straightening the base metals then heating and supplying the same to the molding section, subsequently cutting the same and cold pressing the moldings.
CONSTITUTION: Base metals 65 are straightened by a straightening device B, after which they are heated to about 400°C in a heater C and are supplied to a nut former machine D. Here, the blanks are subsequently cut by cutting and holding means. The blanks then undergo first beveling then the other beveling by means of the second die and punch, forming about half portions of lower hole by means of the third die and punch, and reducing of the lower hole by means of the fourth die and punch, whereby the hexagonal finished moldings are cold-pressed. In this way, the finished moldings of stainless steel nuts are automatically produced, whereby working efficiency is improved. There is no need for applying oxalating to the base metals as a lubricant for preventing seizure and for surface finishing.
