METHOD AND APPARATUS FOR MANUFACTURING ribbed panels

摘要

1. A method for manufacturing ribbed panels comprising preliminary and final deformation of the workpiece at the same temperature with a holding time under the force influence, characterized in that the pre-straining is carried out sequentially in the blank area of ​​portions 2, 3, etc. times lower blank area gradually forming the entire surface of the tool at speeds of from 0.01 to 10 mm / sec and a specific pressure determined by zavisimosti2. An apparatus for performing the method fixed in die block for isothermal forging, comprising upper and lower plates, heating elements, a die and punches, fixed in punch holder and having a cavity the shape and dimensions of the panel edges, characterized in that it additionally administered two or more punch holder connected a top plate device through the guide column, one of the plungers is rigidly fixed and the other movable in the direction of the force stamping punch holder between E and the upper plate unit has thrust sliding bracket with a mechanism for their displacement.
