Uncoiling punching die and punching technology

Abstract

The invention discloses an uncoiling punching die. The die comprises an upper die holder fixed to a machine tool upper table board and doing motion close to or away from a lower die holder along withthe machine tool upper table board, a part erecting plate, an opening male mold, a first punching male mold, a positioning assembly and a pressing plate. The upper die holder and the lower die holderare sequentially provided with three forming die blocks according to the machining sequence, the opening male mold and an opening female mold are matched to punch a positioning opening in a coil, thefirst punching male mold and a first punching female mold are matched to punch a positioning hole, the positioning assembly is fixed to the part erecting plate, and comprises a positioning plate and amovable rod, the movable rod slides along a sliding groove in the positioning plate to enable the movable rod to be close to or away from the coil, the side wall of the positioning assembly is in sliding connection with the coil, and when the movable rod slides to the positioning opening of the coil, positioning of the coil is finished. The invention further discloses a punching process of the uncoiling punching die. Compared with the prior art, continuous punching molding is achieved, through arranging of inserts, multiple blanks can be punched at a time, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of component stamping, in particular to an uncoiling blanking die and a blanking process. Background technique [0002] In the actual production process, some stamping parts need to be blanked before forming. After the raw material is punched into a blank of a certain shape, the blank is punched into the required shape with a forming die. At present, the main method of blanking is manual blanking. The manual blanking mold can only drop one piece of material through one piece of square material at a time, and after blanking, the blank needs to be manually removed and coded. The blanking efficiency is low and at the same time It increases the chance of scratches for workers; and manual operation of code materials can easily cause quality defects such as bumps on the surface of the board; only one piece of single blank can be dropped, which also results in low utilization rate of materials.
