Swing blanking die for uncoiling and blanking line

Abstract

The invention relates to a swing blanking die for an uncoiling and blanking line. The swing blanking die consists of a lower die component and an upper die component and is characterized in that: the lower die component comprises a horizontal lower die seat, a lower swing die and rotary air cylinders; the lower swing die is arranged on the upper surface of the lower die seat in a horizontal swinging manner through guide seats at two ends of the lower swing die; two ends of the rear part of the lower swing die are hinged with the rotary air cylinders respectively; the two rotary air cylinders drive the lower swing die to swing; vertical upper die guide columns are fixedly arranged on the upper surfaces of the guide seats at the two ends of the lower swing die; lifting air cylinders are symmetrically and vertically arranged on the guide seats on two sides of the upper die guide columns; the upper die component consists of an upper swing die and an elastic buffer unit; the upper swing die is arranged in parallel on the upper part of the lower swing die through the lifting air cylinders fixedly arranged on the guide seats; and the elastic buffer unit is fixedly arranged on the upper surface of the upper swing die. The swing blanking die for the uncoiling and blanking line has scientific and rational structure and design and can realize continuous blanking of trapezoid materials, so the utilization rate of raw materials is increased, the production cost is reduced effectively, and the economic benefit and the competitiveness of an enterprise are improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, in particular to a swing blanking die for an uncoiling blanking production line. Background technique [0002] At present, in the production of automobile outer panels, uncoiling and blanking of rough blanks is an important step to ensure product quality. The accuracy, cost and efficiency of uncoiling blanking equipment directly affect the economic benefits of automobile outer panel manufacturers. At present, when processing automobile outer covering parts, blanking is often required to be in an irregular shape, such as an isosceles trapezoid or a right-angle trapezoid. The blanking mold in the existing blanking equipment is a fixed-shaped lifting type blanking, which needs to be processed into a square material first, and then processed into a trapezoidal material. As a result, a large amount of leftover materials are wasted in the blanking process, and the production cost remains...
