High production rate swaging machine and swaging working process

摘要

The present invention is provided for allowing a metal stock (7) to be worked by cold working such as swaging, at a higher production rate and with a higher working productivity. A metal stock (7) may be processed by increasing its density, by refining its crystalline grain structure, and by eliminating any deformation that might occur locally and unevenly due to its metal plasticity.;A swaging machine (1) is capable of running at a higher production rate and with a higher working productivity, and includes a series of several sets of swaging die sets (6) arranged in a tandem along the length of a metal stock (7) being worked, wherein any two adjacent swaging die sets (6) are placed in close proximity to each other, and may be actuated at a different timing with regard to each other so that the following one of the any two adjacent swaging die sets (6) can apply a counter pressure to the metal stock (7) from the side located at a right angle to the side on which the metal stock (7) becomes deformed by flowing toward a relief in the preceding one of the any two adjacent swaging die sets (6).;A swaging process or method is performed continously at a higher production rate by using a series of several sets of swaging dies (6) arranged in a tandem along the length of a metal stock (7) being worked, wherein any two adjacent swaging die sets (6) are placed in close proximity to each other, and may be actuated at a different timing with regard to each other so that the following one of the any two adjacent swaging die sets (6) can apply pressure to the metal stock (7) in a counter direction from the side opposite the side on which the metal stock (7) becomes deformed by flowing toward a relief in the preceding one of the any two adjacent swaging die sets (6).
