Solutions to Sheet Metal Bending Problems

Sheet metal bending and forming is performed on a plate bending machine. Put the workpiece on the plate bending machine, use the brake block lifting lever, then make the workpiece slide into the right position, then lower the brake block to the workpiece, and then press on the bending lever to realize the sheet metal bending. Sheet metal processing is simply a series of processing techniques for bending, riveting and welding metallic materials. In the bending process, there are several common problems that often occur, the causes and solutions that can be applied include the following:

The bent edges are not straight and the size is unstable.

Cause

1. There is no pressing line

2. Inadequate material pressure

3. Low altitude

Solution

1. Punched line design

2. Increase the jacking power

3. Make the height greater than or equal to the minimum size

Workpiece is scratched after bending.

Cause

1. The surface of the material is not smooth

2. The bending radius of the convex die is too small

3. The bending distance is too small

Solution

1. Increase the fineness of the concave

2. Increase the bending radius of the convex die

3. Adjust the bending distance

There is a crack at the bend angle.

Cause

1. Bending radius is too small

2. The grain of the material is parallel to the bending line

3. The spines of the workblank extend to the outside

4. Metal that is difficult to reprint

Solution

1. Increase the bending radius of the convex die

2. Change the blanking layout

3. Making burrs on the inner fillet of the workpiece

4. Annealing or using soft material

The bending surface is thinner

Cause

1. The concave-convex fillet die is too small

2. The concave-convex die distance is too small

Solution

1. Increase the radius of the convex concave fillet die

2. Adjust the clearance of the concave convex mold
