Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
The orientation of indication of the present invention all show benchmark according to Fig. 1.
As shown in Figure 6, aluminium section bar television surface frame 4 includes base plate 41, first side 42, second side 43, first side 42,
Second side 43 lays respectively at the both sides of base plate 41.
As shown in Figure 1, Figure 2, Figure 4 shows, section bar is seamless Bending Mould, including die assembly 1, punch assemblies 2, die assembly 1
Matching with punch assemblies 2, die assembly 1 includes rotary shaft the 14, first moving block the 12, second moving block 13, the first moving block
12 and second moving block 13 can around rotary shaft 14 rotate formed concave die cavity.
Section bar of the present invention is seamless, and Bending Mould is first in die opening state, and first moving block the 12, second moving block 13 is in line
Arranging, during surface frame 4 Bending Processing, the first moving block 12 and the second moving block 13 rotate around rotary shaft 14 and form concave die cavity,
In concave die cavity forming process, surface frame 4 bending plastic deformation is slowly carried out, surface frame 4 bending amount of plastic deformation in the unit interval
Little, it is effectively prevented base plate 41, first side 42, second side 43 stack bending part generating material, improve surface frame 4
Bending effect and outward appearance.
In order to improve the bending effect of surface frame 4, outward appearance, production efficiency further.As shown in Fig. 3, Fig. 5, the present invention's is convex
