[0029] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It is also necessary to explain that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all the contents.

[0030] like Figure 2 The structure diagram of the present invention is shown in FIG. The top cover of the arc half-height display cabinet is made of aluminum alloy: the top cover 9 is fixed to the top bracket of the cabinet body, and the top decorative plate 13 is assembled and fitted with the top cover 9; it is concentric with the layer plate 11 and assembled on the air outlet column 12 of the clamping ball head 3. Its appearance is the same as that of the PVC top cover; however, the aluminum alloy top cover improves the arc accuracy and overall strength, so that the cabinet body assembly and splicing have precision guarantee; and the color can be sprayed at will according to the customer's requirements.

[0031] Arc half-height display cabinet aluminum alloy top cover; the processing method is aluminum extrusion. The extruded parts are straight profiles, which need to be bent into a semicircular shape to meet the assembly requirements of the arc half-height display cabinet. Because the profile material is aluminum alloy, which is inherently very hard, and the cross-section and bending diameter are too small, conventional bending and rolling cannot be produced. The arc top cover is also wrinkled and deformed on the surface and cannot be used. Figure 3 The cross-section of the aluminum alloy top cover is shown in the figure. The profile surface is a transition of arc contour surface, which improves the rounded appearance of the half-height display cabinet; at the same time, it also makes it impossible to process the normal bend.

[0032] Aiming at the problem of bending aluminum alloy top cover, a set of equipment specially used for bending arc section profiles is designed. Figure 4 As shown; the lifting arm 6 and the machine base 10 of the equipment are adjusted to a horizontal state. Fix the straight section of the top cover 9 with the upper clamping piece 4 and the lower clamping piece 5 of the clamping ball head 3. Then fit and lock the outer contour limit mold 7 and the outer contour of the top cover 9. Start the cylinder mounting seat 1 and the cylinder 2 to pre-tighten the clamping ball head 3 and the top cover 9 and stretch them to bend. Make preparations for the bending clamping.

[0033] If the clamping ball head and the profile do not distinguish the tensile strength of the clamping position during the bending process, the profile will be subjected to the stress of its own cross-sectional shape during the bending process, resulting in wrinkles and deformation, which will affect the surface appearance and installation dimensions. To address this problem, a local stretching mechanism is specially designed, such as Figure 5 As shown in the figure, the straight section of the top cover 9 is engaged and fixed with the upper clamping piece 4 and the lower clamping piece 5 of the clamping ball head. A tension of 350 N is applied to the upper clamping piece 4, and a tension of 220 N is applied to the lower clamping piece 5, so that different cross-sectional positions of the top cover 9 are subjected to different forces. This releases the stress during the bending process of the top cover and ensures the arc and flatness after bending.

[0034] like Figure 6 As shown, it is a schematic diagram of the structure after the straight section of the top cover 9 and the upper clamp 4 and lower clamp 5 of the clamping ball head 3 are clamped with different tensile forces. The cylinder mounting seat 1 and the cylinder 2 are pressurized to straighten the top cover 9 profile. Then the stretching arm 6 is rotated so that it has an angle of 50° with the machine base 10 to bend the top cover 9. The outer contour limiting mold 7 is fixed to the top cover 9 so that the inner contour surface fits onto the inner mold 8 of the disc to complete the rounding. The material of the top cover is determined to be AL6063-T4, which is a soft and non-aging material; this can ensure that the material will not be torn during the bending process and has good ductility.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
