Title:

STRETCH FORMING SYSTEM, AND STRETCH FORMING METHOD

Document Type and Number:

Japanese Patent JP2014079781

Kind Code:

A

Abstract:

To reduce burdens of an operator.

A stretch forming system has: jaws J_L, J_R which sandwich an end edge part of a work W; a metal mold D which is arranged between the jaws J_L, J_R and brought into contact with the work W; a plurality of control axes J_D1-J_D2, J_L1-J_L6, J_R1-J_R6 which change relative positions and postures of the jaws J_L, J_R to the metal mold D, and has: a jaw locus calculation part 56 which calculates loci P_JL, P_JR of the relative positions and postures of the jaws J_L, J_R to the metal mold D when the metal mold D is moved in a vertical direction and the work W is wound around the metal mold D under a restriction condition that the positions and the postures of the jaws J_L, J_R are freely changeable except that movement in the vertical direction is restricted; and a control axis operation pattern calculation part 58 which calculates operation patterns of the plurality of control axes J_D1-J_D2, J_L1-J_L6, J_R1-J_R6 for realizing the loci P_JL, P_JR of the jaws J_L, J_R.
