Stamping process of double-folded-edge back plate structure

Abstract

The invention discloses a stamping process of a double-folded-edge back plate structure. The stamping process comprises the following steps that S1, protruding is conducted, specifically, protruding is conducted on a middle forming area of a back plate to form a convex hull structure, meanwhile, hole drawing is conducted on the back plate at the periphery, and a circle of semicircular deep drawingribs are arranged on the periphery; S2, plane shaping and partial edge cutting are conducted, specifically, a cutting device is used for conducting cutting treatment on part of the edge of the back plate; S3, edge cutting and punching are conducted, specifically, the cutting device is used for conducting cutting treatment on the outer dimension of the back plate, and then a punching device is used for conducting punching treatment on the positions of screw holes in the periphery of the back plate; and S4, bending and positioning convex point forming are conducted, specifically, a bending device is used for bending the edge of the back plate by a certain angle, and then the folded edge is bent again. According to the stamping process of the double-folded-edge back plate structure, throughimplementation of the whole process of the stamping process of the double-folded-edge back plate structure, double folded edges are used for replacing a traditional single-folded-edge structure machining process, and machining of the whole back plate is more reasonable and efficient.

Description

technical field [0001] The invention relates to the technical field of punching technology, in particular to a punching technology of a double-folded backboard structure. Background technique [0002] Flat-panel display is a high-tech developed rapidly in recent years. It has many advantages: thin and light, low voltage, no X-ray radiation, no flicker, no static electricity, long service life, etc. Therefore, flat-panel display is widely used in military and civilian fields have a very wide range of uses. [0003] As an important part of the ultra-thin flat-panel display, the backplane has a hemming structure around it. If a single hemming structure is used, it is easy to scrape foreign matter when the backplane is assembled with the middle frame of the display. At the same time, the current stamping process is basically Multiple stamping devices are used to stamp the back plate. For example, four holes need to be punched on the back plate, either two holes on the same side...

[0003] As an important part of the ultra-thin flat-panel display, the backplane has a hemming structure around it. If a single hemming structure is used, it is easy to scrape foreign matter when the backplane is assembled with the middle frame of the display. At the same time, the current stamping process is basically Multiple stamping devices are used to stamp the back plate. For example, four holes need to be punched on the back plate, either two holes on the same side, or four holes together, which increases the cost of the stamping production process. For this reason, Propose a stamping process for double-folded back panel structure
