Processing method of metal shell of electronic equipment and metal shell

The invention aims to provide a processing method of a metal shell of electronic equipment and the metal shell, the metal shell comprises a concave battery cover and a middle frame, the concave battery cover is provided with a positioning column, and the middle frame comprises a middle frame block and at least one middle frame strip; the concave battery cover is formed by stamping a piece of battery cover hardware into a concave shape, upsetting and thickening the side wall of a concave shell material, bending the top end of the side wall and then performing CNC forming, and the bent part of the top end of the side wall is subjected to CNC processing to form a TP eave; the middle frame is formed by dispensing four splicing blocks on the concave battery cover, and the middle frame is laterally pushed below the TP eave; all the middle frame strips are fixed on the periphery of the concave battery cover based on the positioning holes of the middle frame strips, the positioning holes of the middle frame blocks an
