Cabinet in the process of production there are very main seven procedures, the basic is: product design - shear blanking - blanking processing - bending processing - welding cabinet

The product design

The kind of cabinet product design is different, its procedure is not the same, the main task of cabinet design is the product structure of the new product program, the cabinet design of the whole machine, must organize the relevant departments to the product structure of the advanced, technology and use performance of the operation of the review, improve the design.

The first process of cabinet production - cutting

The shearing equipment used in the cabinet industry is the gantry shearing machine, the gantry shearing machine is the most widely used of a kind of shearing equipment, its blade is long, can cut a wide gantry shearing machine according to the location of the transmission mechanism, divided into two driving and driving. The transmission mechanism of the next drive gantry shears is at the bottom of the shears, the frame is lighter, but the area around the shears is larger. When the thickness of the shear is thick, cut the plate below 5mm.
Cabinet parts stamping
Stamping production mainly USES stamping equipment and molds to achieve the metal material processing process, so the network server cabinet stamping process has the following characteristics:
1, high productivity and simple operation, easy to achieve mechanization and automation, especially suitable for mass production.
2, stamping parts surface light, stable dimensional accuracy, interchangeability, low cost.
3. Parts with high strength, large stiffness and small weight can be obtained under the condition of less material consumption.
4. Parts with complex shapes that are difficult or impossible to be processed by other processing methods can be obtained.
Cabinet workpiece bending processing technology
Bending refers to the metal sheet material under the pressure of bending machine mold or lower mold, first through elastic deformation, and then into plastic deformation, in the beginning of plastic bending stage,
The inner surface of the v-groove is gradually compacted, and the radius of curvature and bending moment arm are also gradually compacted
V-bend, which is commonly known as bending.
Network server cabinet workpiece bending forming is often carried out in mechanical press, friction press or hydraulic press, in addition to the plate bending machine, pipe bending machine.
Welding process in cabinet production
1. The welding seam of the server cabinet should be neat and uniform, no cracks, edging, gouges, burn through and other defects are allowed. Slag, blowhole, weld lump, pit and other defects, appearance.
2. The welding is firm and reliable, and the solder on the outer surface of parts should be filled in place without leaving any gaps.
3. During the welding operation of the server cabinet, welding slag and arc damage are not allowed in other non-welding parts, especially the visible parts. The slag should be removed after welding.
4. The surface of parts should be polished and polished after welding, and the surface roughness value is 12.5. For some welded surfaces in the same plane, the surface shall not be treated.
5. The welding operation shall establish a process to eliminate the welding stress as far as possible. Welding should have tooling, do not allow parts due to welding and various deformation.
1. Degreasing and derusting:
2. Phosphating:
3. Powder spraying:
