1. Equipment chassis shell processing bending

When bending, first of all, sheet metal manufacturing co., ltd. should determine the tool and groove used in bending according to the size on the drawing and the thickness of the material. The key to choosing the lower mold is to avoid the collision and deformation of the product and the tool (the same product can use different types of lower molds), and the choice of the lower mold should be determined according to the thickness of the wood.

Secondly, you must bend successively. The general bending rule is first small and then large, first unique and then general. For workpieces with edges to be crushed, bend the workpiece to 30-40 degrees first, and then grind the workpiece to death with a leveling die.

2. Machining Surface Solution of Equipment Chassis

The surface of the workpiece is solved after the bending, riveting and other processes are completed. The surface treatment methods of different plates are different. The surface of the shell sheet metal is generally plated after processing. After plating, no spraying treatment is carried out. Pickling and phosphating are used, and then spraying treatment is carried out. Clean the surface of the plate, deoil, and then paint.

Stainless steel plates (with mirror plate, fog plate, brushed plate) can be brushed before bending without painting. If painting is required, it should be polished; the aluminum plate is generally oxidized, and different oxidized background colors are selected according to different colors.

3. during the processing of the equipment chassis shell, it usually goes to the next process after the blanking is finished, and different workpieces go to the corresponding process according to the processing request.

sheet metal processing and production include bending, riveting, tapping on the opposite side, welding, convex hull and segment difference. sometimes one or two nuts or studs are bent, including the convex hull of the mold and the segment difference, after avoiding the interference of other processes, the required processing cannot be completed. When snap‑fit tabs are located on the top or bottom shell, if they cannot be welded after bending, they must be machined prior to bending.
