Problems solved by technology

[0004] The technical defects of the above two schemes are: positioning holes, protrusions, depressions, chamfers, hooks, sprouting and other processes are completed first on the plane reference, and after the curved surface is formed, the relative positions of these process shapes occur. Changes, large deviations in size
Unstable product quality increases assembly difficulty

Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the mode of the present invention is further elaborated:

[0014] image 3 As shown, according to the inventive scheme, 6 sets of molds made according to the new scheme are respectively installed on 6 stamping machines for installation and debugging in place.

[0015] The general division of labor is as follows:

[0016] The coil material is fed into the No. 1 punching machine by the feeder, and beading is provided on the whole circumference ( figure 2 ) 1, press the blank, stretch out the box with the bottom of the arc surface 2, and at the same time, the convex hull on the arc surface is also stretched together.

[0017] The semi-finished product in the No. 1 punching machine is taken out by the mechanical arm and transferred to the No. 2 punching machine. The shape of the product is cut, the convex hull is shaped on the arc surface, and the hook is formed.

[0018] The semi-finished product in the No. 2 punching mac...

Abstract

The invention relates to a production technology for stamping molds for back boards which are important structural components of liquid crystal displays of curved-surface televisions. The technology is characterized in that firstly, molding is performed on first engineering curved surfaces, subsequent processes such as trimming, convex hull reshaping, hook molding, hole stamping, stamp-marking, burr pressing, little bending, stamp-marking, sprouting, all-around bending and the like are performed on curved surfaces, and the curved surfaces are formed by drawing sheet metal parts into box-shaped bodies with bottoms being curved surfaces in first engineering and then cutting off excess materials; and during drawing of the curved surfaces, drawing pressing ribs are arranged on the molds, and drawing and stabilization of the curved surfaces are facilitated.

Description

technical field [0001] The invention relates to a stamping die production technology for the back plate of an important structural component (BOT CHASSIS) of a curved TV liquid crystal display. Background technique [0002] (OLED BOT CHASSIS) curved backplane is an important structural component used to install curved liquid crystal panels and circuit boards. The structure of the curved backplane is similar to that of the flat backplane. There are curved molding surfaces around it. There are many positioning holes, protrusions, depressions, chamfers, undulations of various shapes, hooks, sprouts, etc. on the backplane. structure, the difference is that all the process structures of the curved backplane are completed on the curved surface, which is more difficult to produce. [0003] Existing mold production methods: Method 1: Production according to the general planar backplane method first, and on the basis of the completion of each process (including full-circle bending) ...
