Problems solved by technology
However, when bending the frame at 180°, due to the narrow space, the effect of bending the frame with a general bending machine is often not good enough, which may easily lead to a reduction in thickness caused by deformation of the frame at the 180° bend or a 180° bend. big gap problem

Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0028] like Figure 2~5 The frame forming process of the display backplane shown includes the following steps:
[0029] Step 1: Break the difference at the edge of the backplane 10 to form a first bend 11 and a second bend 12, the second bend 12 is close to the edge of the backplane 10, and the bending angle of the second bend 12 is is 90°; if figure 2 As shown, the breaking difference is two deformations of the back plate, that is, the first bending 11 and the second bending 12 , through the upper and lower dies once molding.
[0030] Step 2: Carry out the first lateral push on the first bend 11, so that the bending angle of the first bend 11 is an acute angle; ...

The invention relates to the technical field of display frames, in particular to a frame forming process of a display backboard. The frame forming process comprises the following steps of 1, breakingthe edge of a backboard to form a first bending and a second bending, wherein the second bending is close to the edge of the backboard, and the bending angle of the second bending is 90 degrees; 2, carrying out first side pushing on the first bending position, so that the bending angle of the first bending is an acute angle; 3, carrying out side pushing on the first bending position to enable thebending angle of the first bending to be 0 degree; and 4, bending the backboard to form a third bending, wherein the bending angle of the third bending is 90 degrees, so that an upper supporting platewhich is connected with the second bending is parallel to the backboard which is not bent. According to the frame forming process, the differential process is interrupted, the bending step is reduced, the bending efficiency is improved, the folding is realized by two-time side pushing on the first bending position, the folding and forming of the frame can be more easily controlled by the two-timeside pushing, and the forming effect is better.
Description
technical field [0001] The invention relates to the technical field of display frames, in particular to a frame forming process of a display backplane. Background technique [0002] Chinese invention patent CN108307134B disclosed an integrated TV backplane and its processing technology on July 20, 2018, in which the frame of the TV backplane is bent three times to form a double-layer structure that supports the screen and optical components. like figure 1 As shown, this structure is integrated with the backplane without any connecting parts, which effectively simplifies the assembly process, reduces the size of the entire backplane, and realizes the thinner and lighter requirements of the final product. [0003] When processing the above-mentioned frame, the processing technology disclosed in the above-mentioned patent is to first bend the outermost part by 90°, then reversely bend the rear part by 180°, and finally bend the rear end Carry out 90° bending, so that the back...
