HYDROFORMING CROSS MEMBER DIES FOR PREVENTING DEFECT OF COMPLETED WORKPIECE

摘要

A hydroforming cross member mold is provided to prevent processing flaws of a completed product by forming a mold for forming a cross-member product, thereby accurately forming holes and grooves are in the cross-member product according to dimensional tolerances when forming the cross-member product. In a cross-member mold for hydroforming using a hydroforming process of passing high pressure water through a tube at room temperature to deform the tube, a hydroforming cross member mold for preventing processing flaws of a completed product is characterized in that holes are formed in a cross-member forming mold, and grooves are formed on end portions of the cross-member forming mold such that accurate positions for the holes and grooves are selected when forming holes in a cross-member article and machining side faces of the cross-member article according to dimensional tolerances in a subsequent processing process.
