Universal sheet metal case and machining process thereof

Abstract

The invention provides a universal sheet metal case and a machining process thereof, which relate to the technical field of case machining. The universal sheet metal case comprises a bottom plate; bent sheet metal side plates are arranged on the two sides of the bottom plate respectively; two strip-shaped fixing plates are arranged on the side walls, close to the bottom plate, of the bent sheet metal side plates; a top plate is arranged above the bottom plate; the two side walls of the top plate are both located between the two strip-shaped fixing plates; a bent sheet metal rear panel is arranged at one end of the top plate; a front panel is arranged on the side, away from the bent sheet metal plate rear panel, of the top plate; and two counter bores are formed in the surfaces of the two ends of the bottom plate, the ends, close to the front panel, of the bent sheet metal side plates and the end, close to the front panel, of the top plate correspondingly. The side wall of the bottom end of the bent sheet metal rear panel and the four side walls of the side, close to the bottom plate, of the front panel are each provided with two lugs. The problems that an existing sheet metal caseis large in number of machining and assembling parts, long in assembling time and inconvenient to disassemble and assemble, and meanwhile direct dust prevention is inconvenient to conduct in the heatdissipation process are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a general-purpose sheet metal chassis and its processing technology. Background technique [0002] The sheet metal chassis is a chassis that is required after cooling and forming using a comprehensive cold processing process for metal sheets. The processing technology includes shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming (such as automobile body) and so on. Its remarkable feature is that the thickness of the same part is consistent. With the application of sheet metal more and more widely, the design of sheet metal parts has become a very important part of product industrial development. Sheet metal has light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, With the characteristics of good performance in mass production, it has been widely used in electronic appliances, communicat...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a general-purpose sheet metal chassis and its processing technology, which solves the problem that the existing sheet metal chassis has many assembly parts, long assembly time, and inconvenient disassembly and assembly. The problem that the dustproof effect is not good enough to dissipate heat through the cooling holes
