Die device for achieving drawing flanging forming

Abstract

The invention relates to the field of stamping dies, in particular to a die device for achieving drawing flanging forming. The device comprises an upper die base and a lower die base, wherein a male die is installed in the upper die base, a female die is installed in the lower die base beside the male die, a forming groove is formed in the lower end of the end part, on the same side with the female die, of the male die, a round angle is formed in the upper end part of the forming groove, an upper material pressing plate is arranged in the position, corresponding to the upper portion of the female die, of the upper die base, the upper material pressing plate can move in a reciprocating mode in the vertical direction in the forming process, a lower material pressing plate is arranged in theposition, corresponding to the lower portion of the male die, of the lower die base, the lower material pressing plate can move in a reciprocating mode in the vertical direction in the forming process, before the forming process, a gap is formed between the lower end surface of the upper material pressing plate and the upper end surface of the female die, the gap can allow a part to pass through,the position of the upper end surface of the lower material pressing plate is not higher than the horizontal position of the upper end surface of the female die, and an upper pressure spring is installed between the upper material pressing plate and the upper die base.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a die device for realizing drawing flanging forming. Background technique [0002] With the development of technology and the increasingly fierce market competition, the traditional stamping process has also been changed to reduce the number of stamping processes and machine tools used, thereby achieving the purpose of saving costs. [0003] In the field of stamping dies, drawing is a stamping process that changes flat wool or process parts into a curved surface shape. The structure of the existing drawing device mainly includes an upper mold base and a lower mold base, and a punch is installed in the upper mold base. , a concave mold is installed in the lower mold seat on the side of the punch, a molding groove is made at the lower end of the same side of the punch and the concave mold, and a rounded corner is made at the upper end of the molding groove. During the process, the pun...

Problems solved by technology

Since the process parts are always moving downstream during the flanging forming process, and the inflow speed remains unchanged, the process parts are prone to wrinkling and stacking during the forming process
