Custom Stainless Steel Sheet Metal Parts Cabinet Metal Box Enclosure​

Many equipment Enclosure around us need sheet metal processing, such as meter boxes, alarm boxes, distribution boxes, ATM machines, intelligent disinfection channels, vending machines, telecommunication cabinets, etc., which are all manufactured by sheet metal processing factories.

There are many mechanical equipment used in sheet metal processing plants, because of the many processes and a wide range of processed products, mainly CNC punching machines, laser cutting machines, milling machines, planers, drilling machines, boring machines, broaching machines, grinding machines, polishing machines, shearing machines, welding machines Wait. These mechanical devices can be subdivided.

Points for attention in sheet metal enclosure processing

1. In production, each process must be processed according to the drawings, processes and standards; when the drawings and the process do not conform to the process, the process shall prevail.

2. When the drawings and processes have tolerance marking requirements, they shall be processed according to the tolerance requirements.

3. If the drawings and processes do not have tolerances noted, they shall be processed according to GB/T 1804-92m.

4. When the dimensions and tolerances marked on the drawings are inconsistent with the dimensions and tolerances required by the process, process them according to the process requirements.

5. The cabinet shape is processed according to the positive tolerance of the allowable tolerance, and the chassis shape is processed according to the negative tolerance of the allowable tolerance.

6. The shape of the door is processed according to the negative tolerance of the allowable tolerance, and the positive tolerance is strictly prohibited.

7. Holes without tolerance requirements shall be processed according to the positive tolerance of GB/T 1804-92 m-level and on the upper side.

8. When process holes must be opened for all products due to electroplating or hot-dip galvanizing, the open process holes should be in an invisible position on the front of the product. For all kinds of aluminum alloy panels, when the shape is not specified with tolerance, it shall be processed according to the negative tolerance of GB/T 1804-92 f level and downward.

9. For the process sequence of bending after riveting, special care should be taken when arranging the process. If the edge is too small, the bending will interfere after riveting.

10. Parts with electroplating requirements are required to be riveted after electroplating. If it is difficult to press riveting after bending, the process should indicate that auxiliary riveting tooling is required.

11. In the case where the thick and folded edges of the sheet are too small, more allowance must be left for the local dimensions that cannot be folded in place, and the process sequence of flushing or milling off the excess after bending.
