Introduction to Manufacturers of Double-Flange Combination Dies: Precautions for Using Double-Flange Combination and Bending Dies

Introduction to manufacturers of double-flange combination dies: When shutting down the press brake, place blocking pads beneath the lower dies on both sides of the hydraulic cylinders to support the upper double-toggle linkage as it is lowered onto the pads. First, deactivate the automatic control system program, then turn off the power supply. A press-brake die is a tool used in press-brake machines for forming and processing sheet metal; such specialized tools are composed of a wide variety of components, with different types of dies comprising different component sets. The primary mechanism involves altering the physical state of the workpiece material to achieve the desired part geometry. It is a method employed under the action of the press brake’s force to transform a blank into a finished product with specific shape and dimensional specifications. Assembly and adjustment procedure for press-brake dies:

When using bending dies, be sure to thoroughly inspect the machine, then assemble and adjust it according to the prescribed procedure, taking personal safety precautions during adjustment.

1. Equipment adjustment:

When using a bending die, it is essential to understand the equipment’s characteristics. Start up the press brake, carefully adjust and inspect it, and check for any accumulated dust or metal chips from previous use. This will help prevent unnecessary damage during future operations.

2. Adjustment of roller stroke arrangement:

Introduction to manufacturers of double-flange combination dies: First, inspect the thickness of the bending die and the proportion of the upper and lower dies to ensure there are no issues. Typically, the roller should be positioned at the stroke-limit switch on the power supply line—this is a critical consideration; otherwise, the die may not function properly. Yet some operators frequently make this mistake.

3. Adjustment of the itinerary management module:

After adjusting the stroke settings for the roller, the next step is to modify the module limit points. In most cases, when the control module reaches its upper limit, the module and power switch must be properly configured. This helps eliminate any residual positioning errors of the module, and through these practical adjustments, production efficiency can be significantly improved. During this process, it is also necessary to implement deceleration control for the component. Specifically, when the control module descends to its lower dead center, its speed must be reduced to ensure the safety of both the equipment and the mold.

4. Variation in clearance:

Next, we will examine the variation in the gap between the bending dies. First, measure the clearance between the upper and lower dies; the effective gap should be determined based on the specific sheet metal being bent.

5. View Angle Adjustment:

Adjusting the bending angle is also a critical step; the selected angle must be in accordance with the product specifications. Generally, for a 90° bend, the central angle should be set higher than the angles on either side—sometimes slightly tighter—and this can be adjusted by tweaking the screws on the equipment. However, unless there are specific changes required for this particular product, no further adjustments should be made. During the bending process, refer to the pressure gauge to accurately measure and set the working pressure, then make the necessary pressure adjustments to prevent chipping or breakage of the die edges.
