How to handle the unfolding diagram of the cabinet during Sheet Metal Processing?

The small editor of Hunan sheet metal processing manufacturer answers for you: The first thing to do before the production of the cabinet is to design the cabinet production drawings. Only by designing the drawings can the cabinet style desired by the customer be made, and the production department knows how to make the cabinet. Therefore, the design drawings of the cabinet are an important part of the production of cabinet ZUI. The cabinet of sheet metal processing is one of many cabinets, and it also needs to design the drawings before production. But pay attention to the unfolding diagram and the floor plan when sheet metal processing. Generally speaking, the unfolding diagram is a 2D floor plan that is unfolded according to the 3D part diagram.

So how does the sheet metal processing manufacturer handle the unfolding diagram of the cabinet?

1. Generally speaking, the way of sheet metal processing in Zhuzhou should be reasonable and convenient. Doing so can save materials.

2. Rational planning of the gap between parts and the way of hemming, generally speaking, T = 2.0 or less, the gap is 0.2, T = 2-3, the gap is 0.5, and the hemming method uses long sides and short sides (door panels).

3. Reasonably consider the tolerance shape size and hole size. Generally, for the shape size, the negative difference goes to the end, and the positive difference goes half. For the hole size, it is the opposite. Generally, the positive difference goes to the end, and the negative difference goes half.

4. Draw cross-sectional views of riveting, tearing, punching bumps, and other positions.

5. Strictly check the material, plate thickness, and plate thickness tolerances.

6. For areas prone to errors, we need to use special fonts to focus on them.

7. We also need to use eye-catching text to treat areas that need to be sprayed for protection.

8. For parts with excessive size, we should enlarge them.

9. For special angles, especially bending angles, the internal radius should be tested and folded to be expanded.

Therefore, Hunan Sheet Metal Processing reminds everyone that the small sheet metal cabinet design drawings play a role that can be said to be inaccurate in words; the small sheet metal cabinet design drawings contain very esoteric skills, which are not understood by any one person. Generally speaking, only professional sheet metal processing technicians can understand the meaning of its expression. Chassis cabinet sheet metal processing manufacturers must not be careless about cabinet drawings.
