What should we pay attention to in sheet metal bending process?

Sheet metal bending is a common processing method and one of the basic processes for making sheet metal components. When bending sheet metal, you need to pay attention to the following aspects.

1. Material selection.

First of all, it is necessary to select the appropriate material, which must meet the processing requirements on the one hand and the usage requirements on the other hand. Generally, the materials used in sheet metal bending processing include cold-rolled plates, hot-rolled plates, stainless steel plates, etc. Different materials have different mechanical and chemical properties, and appropriate materials need to be selected for processing.

2. Mold selection.

Mold is a very important part of sheet metal bending, which directly affects product quality and process efficiency. When selecting a mold, it is necessary to consider the requirements of the product's process performance, dimensional accuracy and surface quality. Choosing the right mold can improve the processing quality of the product.

3. Bending angle.

The bending angle is an aspect that needs attention during the sheet metal bending process. There may be some irregular or non-standard angles. During the bending operation, it is necessary to control the bending strength and angle, and follow the correct operating procedures to ensure the accuracy of the product.

4. Bending radius.

When bending sheet metal, the bending radius is also a parameter that needs attention. The bending radius will affect the size and surface quality after bending. When performing bending operations, it is necessary to select an appropriate bending radius based on the size and shape of the workpiece.

5. Bare edge processing.

The edges of sheet metal after bending are often exposed, which requires corresponding processing of the exposed edges. Sheet metal processing manufacturers say that bare edge processing includes grinding, cutting, rust prevention and other operations. The treated bare edges can improve the quality and protective properties of the product.

6. Flanging processing.

In the sheet metal bending process, flanging is a common process. Flanging is to roll up the edge of the sheet metal to increase the lateral stiffness of the sheet metal. During the flanging operation, it is necessary to select the appropriate flanging width and angle according to the size and shape of the workpiece to ensure that the flanged product meets the usage requirements and surface quality.

In short, sheet metal bending is a complex process involving multiple links and parameters. To ensure the quality and efficiency of the sheet metal bending process, attention needs to be paid to selecting appropriate materials, molds, bending angles, bending radius and other parameters. At the same time, the bare edges and flangings need to be processed accordingly, so that the final sheet metal Gold products are of high quality and excellent performance.
