Problems solved by technology

[0004] The present invention designs a folding and flanging die structure of a stamping die, and the technical problem it solves is that because the flanging die structure of the existing stamping die adopts two kinds of pressures of horizontal stamping and vertical stamping at the same time, there is no pair of stamping parts on the lower die. Simultaneous positioning and pressing are prone to accuracy deviations

Abstract

The invention relates to an edge folding and turning die structure of a punching die. The edge folding and turning die structure comprises an upper die (1) and a lower die (2). The edge folding and turning die structure is characterized in that a punching piece pressing and limiting mechanism is arranged on a lower die holder (21). The punching piece pressing and limiting mechanism is arranged on the lower die holder and can press a punching piece after positioning the punching piece, and the punching quality of the punching piece is ensured.

Description

technical field [0001] The invention relates to a stamping die, in particular to a folding and flanging die structure of the stamping die. Background technique [0002] Chinese patent: The flanging die of the continuous stamping die of the automobile safety belt hanger, the application publication number CN102012663A discloses a flanging die on the stamping die. Easy to unmold. [0003] However, since the flanging die of the continuous stamping die of the automobile seat belt hanger adopts both horizontal stamping and vertical stamping pressures, in order to ensure the stamping quality of the stamping parts, the stamping parts must be positioned and pressed on the lower die at the same time. Otherwise, it is prone to accuracy deviation. Contents of the invention [0004] The present invention designs a folding and flanging die structure of a stamping die, and the technical problem it solves is that because the flanging die structure of the existing stamping die adopts tw...
