Abstract
PURPOSE:To obtain a formed product of high dimensional accuracy by pressing the straight side of a product to be formed from side to bend inside by specified amount in the final stage of drawing of a square tube, and returning to a specified shape by spring back after taking out the formed product. CONSTITUTION:Grooves 1d are formed at specified positions of four faces of a hole 1a of a forming die 1, and pressing tools 8 that fit to the grooves 1d are provided. Recessed parts 4b are formed at specified positions on four faces of a punch 4, and the periphery of a thin plate 2 to be formed is pressed between the flat part 1c of the die 1 and a wrinkle presser 3. Then, it is drawn by a punch 4 and a formed product 2a is obtained. Straight side 4 of the formed product 2a is bent to the inside by the pressing tool 8 and a pressure ram 9. The pressing tool 8 is returned to the groove 1d and the presser 3 is raised and the formed products 2 is removed. The straight side of the formed product 2a is returned to a specified shape by spring back. Thus, the square tube drawing of very thin plate or a plate having large deformation resistance can be made with high dimensional accuracy.
