Embodiment 1

[0031] A process for forming a circle around a side wall of a metal shell, which comprises the following steps:

[0032] (1) 90-degree bending forming: the thin material sheet is fixed on the 90-degree forming mold and then bent, such as figure 1 In the case shown, the size of the outer fillet at the bend is 90 degrees;

[0033] (2) Oblique 45-degree molding: Fix the outer shell that has been bent at 90 degrees on the oblique 45-degree molding die and push the molding. The edge material flows to both sides, so that the corners are in a fan-shaped structure, resulting in figure 2 Slanted 45 degree forming prefab shown;

[0034] (3) 150-degree rounding molding: fix the inclined 45-degree molding prefabricated parts on a 150-degree forward mold for pre-rounding horizontal side push molding, so that the two side walls except the corners reach 150-degree rounding molding, and the following results are obtained. image 3 The shown 150-degree rounded prefabricated part, wherein t...

Embodiment 2

[0037] A process for forming a circle around a side wall of a metal shell, which comprises the following steps:

[0038] (1) 90-degree bending forming: fix the thin sheet on the 90-degree forming die and bend it to obtain the following figure 1 In the case shown, the size of the outer fillet at the bending position is 90 degrees, wherein the case is made of aluminum sheet, and the thickness of the case is 0.8mm, 1.0mm or 1.2mm;

[0039] (2) Oblique 45-degree molding: Fix the outer shell that has been bent at 90 degrees on the oblique 45-degree molding die and push the molding. The edge material flows to both sides, so that the corners are in a fan-shaped structure, resulting in figure 2 Slanted 45-degree molding preforms shown, such as figure 2 shown;

[0040] (3) 150-degree rounding molding: fix the inclined 45-degree molding prefabricated parts on a 150-degree forward mold for pre-rounding horizontal side push molding, so that the two side walls except the corners reach...

Embodiment 3

[0043] A process for forming a circle around a side wall of a metal shell, which comprises the following steps:

[0044] (1) 90-degree bending forming: fix the thin sheet on the 90-degree forming die and bend it to obtain the following figure 1 In the case shown, the size of the outer fillet at the bending place is 90 degrees, the radius of the outer fillet is 0.5-0.6mm, and the radius of the outer fillet is preferably 0.5mm, wherein the outer shell is made of aluminum material plate. Made, the thickness of the shell is 0.8mm, 1.0mm or 1.2mm;

[0045] (2) Oblique 45-degree molding: Fix the outer shell that has been bent at 90 degrees on the oblique 45-degree molding die and push the molding. The edge material flows to both sides, so that the corners are in a fan-shaped structure, resulting in figure 2 Slanted 45 degree forming prefab shown;

[0046] (3) 150-degree rounding molding: fix the inclined 45-degree molding prefabricated parts on a 150-degree forward mold for pre-...

Abstract

The invention discloses a rounding forming process for a side wall of a metal shell, which comprises the following steps: (1) bending at 90 degrees to form: fixing a thin material plate on a 90-degree forming die and bending to obtain a shell; (2) obliquely forming a shell; 45-degree molding: fix the outer shell that has been bent at 90 degrees on the oblique 45-degree molding die. (3) 150-degree wrapping molding: fix the oblique 45-degree molding prefabricated part on the 150-degree forward mold The pre-rounded horizontal side push molding makes the two side walls except the corners reach a 150-degree rounded forming; (4) 180-degree rounded forming: fix the 150-degree rounded prefabricated parts on the 180-degree forward mold and then complete the round. Horizontal side push molding, so that the sidewalls except the corners reach a 180-degree round shape, and the finished product is obtained. The invention adopts the step-by-step molding method, and the 180° rounded product of the shell side wall and the small round corner of the corner obtained after molding solves the problem of cracking and wrinkling of the 180° rounded side wall and the corner side wall.

Description

technical field [0001] The present invention relates to the technical field of cell phone or notebook computer casing processing, in particular to a process for rounding the side wall of a metal casing. Background technique [0002] The shells of mobile phones and laptops pursue lightness, beauty and compact structure. With the improvement of users' aesthetic requirements, users begin to pay attention to the aesthetics of mobile phone and laptop shells. The traditional round shell needs to be assembled in two parts to form a full circle. However, after the butt assembly, there will be a center line or a dividing line at the bottom, resulting in an extra line after the shell is rounded, which is not beautiful. There are gaps and breaks between components. SUMMARY OF THE INVENTION [0003] In order to solve the technical problem of the gap and the difference between the two components after the casing is rounded by butt assembly, the present invention provides a rounding fo...
