The present invention is to prevent cracking of the material by a stretch forming operations tensile and compressive stresses of high-strength steel material relates to a device for real-compartment frame when producing a stretch forming process by applying a tensile stress stretch molding while the material is formed into a multi-axial direction of the molding material and forming the point corresponding to the compressive stress by using a high-strength steel sheet material As there is a purpose to buffer the pressure and to prevent cracking. ; The present invention is configured hayeoseo accommodating a plurality of gas springs of the mold and stretch-forming point and a pad on top of the spring. ; This gives the invention a plurality of gas springs to stretch and mold forming point by pressing and buffer the high-strength steel material that is molded into a multi-axis direction, when the molding process is complete, the rise easily boost The tensile stress and compressive stress on a multi-axis direction in which the forming material, so being able to have a function corresponding to books because a buffer to prevent cracking, characterized in that the real-compartment can be efficiently performed without failure the manufacture of the garment frame there.
