Forming apparatus

Abstract

A forming apparatus includes a movable frame, a first arm that is supported by the movable frame to be capable of oscillating, a second arm that is supported by the first arm to be capable of oscillating, a holding unit that is capable of holding an object to be formed supported by the second arm, a first oscillating mechanism that applies an oscillating operation to the first arm, a second oscillating mechanism that applies an oscillating operation to the second arm, and a moving mechanism that applies a moving operation to the movable frame in at least one direction.

What is claimed is: 
     
         1 . A forming apparatus comprising:
 a movable frame;   a first arm that is supported by the movable frame to be capable of oscillating;   a second arm that is supported by the first arm to be capable of oscillating;   a holding unit that is capable of holding an object to be formed supported by the second arm;   a first oscillating mechanism that applies an oscillating operation to the first arm;   a second oscillating mechanism that applies an oscillating operation to the second arm; and   a moving mechanism that applies a moving operation to the movable frame in at least one direction.   
     
     
         2 . The forming apparatus according to  claim 1 , wherein:
 the holding unit is supported by the second arm to be rotatable about an axis parallel to a longitudinal direction of the second arm, and   a rotating mechanism that applies a rotational operation to the holding unit is provided.   
     
     
         3 . The forming apparatus according to  claim 2 , wherein the rotating mechanism includes a gear that is provided on an outer periphery of an upper end portion of an air cylinder for grip disposed concentrically in the second arm, and a rack member that meshes with the gear. 
     
     
         4 . The forming apparatus according to  claim 3 , wherein the gear is formed concentrically with the second arm and the air cylinder for grip, and the rack member is supported at an upper end portion of the second arm to be slidable in a front-rear direction. 
     
     
         5 . The forming apparatus according to  claim 1 , wherein the movable frame is disposed above the holding unit. 
     
     
         6 . The forming apparatus according to  claim 5 , wherein the movable frame includes a support plate that is supported by the moving mechanism, and a body portion that extends downward from the support plate. 
     
     
         7 . The forming apparatus according to  claim 6 , wherein a base end portion of the first arm is supported at an extending end portion of the body portion by a first joint shaft parallel to a front-rear direction to be capable of oscillating. 
     
     
         8 . The forming apparatus according to  claim 7 , wherein the second arm is supported at an extending end portion of the first arm by a second joint shaft parallel to the front-rear direction to be capable of oscillating. 
     
     
         9 . The forming apparatus according to  claim 1 , wherein the moving mechanism includes a first moving unit that moves the movable frame in an up-down direction. 
     
     
         10 . The forming apparatus according to  claim 1 , wherein the moving mechanism includes a second moving unit that moves the movable frame in a horizontal direction. 
     
     
         11 . The forming apparatus according to  claim 10 , wherein the moving mechanism includes a third moving unit that moves the movable frame in a horizontal direction perpendicular to a moving direction of the second moving unit. 
     
     
         12 . The forming apparatus according to  claim 1 , further comprising:
 a supply device for an object to be formed that includes a slope for supplying the object to be formed to a delivery position where the object to be formed is to be delivered to the holding unit.   
     
     
         13 . The forming apparatus according to  claim 1 , wherein press forming is performed.
