Manufacturing apparatus for metal molded body

Abstract

There is provided a manufacturing apparatus for a metal molded body. The manufacturing apparatus includes: a die having an elongated shape in plan view; and a plurality of pairs of thrust units disposed along a wall surface with the die disposed therebetween from both sides of the die, wherein the pairs of thrust units have electromagnetic coils that generate reverse traveling magnetic fields, and the pairs of thrust units arranged in a longitudinal direction are set so as to generate the reverse traveling magnetic fields for each series composed of a single thrust unit or a plurality of the thrust units.

1 . A manufacturing apparatus for a metal molded body, the manufacturing apparatus comprising:
 a die having an elongated shape in plan view; and   a plurality of pairs of thrust units disposed along a wall surface with the die disposed therebetween from both sides of the die,   wherein   the pairs of thrust units have electromagnetic coils that generate reverse traveling magnetic fields, and the thrust units arranged in a longitudinal direction are set so as to generate reverse traveling magnetic fields for each single thrust unit or each series composed of a plurality of the thrust units.   
     
     
         2 . The manufacturing apparatus for a metal molded body according to  claim 1 , comprising
 a control circuit that switches directions of traveling magnetic fields of the electromagnetic coils such that the thrust units arranged in the longitudinal direction generate reverse traveling magnetic fields for each desired number of the thrust units.   
     
     
         3 . The manufacturing apparatus for a metal molded body according to  claim 1 , wherein a whole or a part of the die is curved in plan view. 
     
     
         4 . The manufacturing apparatus for a metal molded body according to  claim 2 , wherein a whole or a part of the die is curved in plan view. 
     
     
         5 . The manufacturing apparatus for a metal molded body according to  1 , further comprising
 a thrust unit that causes an obliquely vertical traveling magnetic field, in addition to the thrust unit that causes a horizontal traveling magnetic field.   
     
     
         6 . The manufacturing apparatus for a metal molded body according to  2 , further comprising
 a thrust unit that causes an obliquely vertical traveling magnetic field, in addition to the thrust unit that causes a horizontal traveling magnetic field.   
     
     
         7 . The manufacturing apparatus for a metal molded body according to  3 , further comprising
 a thrust unit that causes an obliquely vertical traveling magnetic field, in addition to the thrust unit that causes a horizontal traveling magnetic field.   
     
     
         8 . The manufacturing apparatus for a metal molded body according to  4 , further comprising
 a thrust unit that causes an obliquely vertical traveling magnetic field, in addition to the thrust unit that causes a horizontal traveling magnetic field.
