When the product drawing is finished it is possible to navigate to the next step in the programming process; to determine first the Tool Setup and after the Bend Sequence.

Line Properties and Adjustments

Introduction

When the cursor is on one of the product lines it is possible to change the properties of that line by selecting Properties.

Projection

Inside the window with line properties, the following projection properties can be programmed:

• Horizontal projection: The horizontal distance a line must measure, regardless of its angle value.

• Vertical projection: The vertical distance a line must measure, regardless of its angle value.

The DELEM DA-69T Product Drawing feature enhances design capabilities with its efficient projection function. This tool allows users to draw diagonal lines between points without manually calculating side lengths. By entering the vertical or horizontal projection distance and pressing Enter, the system auto-calculates and applies the necessary line length to the segment.

Key elements include:

If a projection isn’t possible, the system notifies users on-screen to prevent errors. This feature streamlines design processes, offering precision and ease, thus making DELEM DA-69T Product Drawing an essential tool for optimized production drawings.

Precision selection

The DELEM DA-69T Product Drawing feature provides users with the ability to precisely control the accuracy of line segments, crucial for effective bending operations. When the drawing cursor is on a line, you can set the level of precision by entering the properties and adjusting the ‘Precision’ parameter.

Precision Levels:

• Normal: Standard accuracy suitable for most needs.
• High: Optimizes back gauge stop positions during bend sequence computations for maximum accuracy.
• Closing Dimension: Adjusts back gauge stop to meet specific tolerance requirements.

Example:

A line interval marked should ideally be placed between the back stop and die center for best results.

Notes: While high precision and closing dimension can increase production time, they offer greater accuracy. This precision setting supersedes the “front extend ratio” if set to “comply if possible”.

Insert / delete bend

The DELEM DA-69T product drawing tool offers precise control over your production designs. Here’s how you can leverage its features:

• Inserting Bends: Place the cursor on a line segment (except the end line) to add a new bend, replicating the original side length for consistent design adjustments.
• Deleting Bends: If the cursor is on a bend (angle), you can easily remove it, allowing you to correct or refine your design.
• Deleting End Lines: Position the cursor at the product’s end line to delete it, adjusting the product boundaries as needed.

These functions in DELEM DA-69T product drawing enhance design accuracy and flexibility, optimizing your production process.

Managing Bend Properties

Air bend

The DELEM DA-69T Product Drawing feature simplifies the process of graphically programming a product’s shape. By specifying line lengths, angle values, and other parameters, users can design products with precision. Each bend in a product has its own distinct properties, which can be adjusted by selecting the bend and then accessing its properties.

Bend Type:
The DELEM DA-69T allows users to determine the appropriate bending process. Options include:

• Air Bend: Standard bending with a defined angle and preferred radius.
• Bumping: Used for creating a large radius in multiple airbending steps.
• Hem Bend: Involves a pre-bend at a sharp angle followed by hemming using a special tool.

Angle and Radius:
Users can set precise angle values and program a preferred radius for bends. When a large radius is needed, a special radius punch is employed, or the bumping method can be used if the punch is unavailable. The computed radius results from control settings and the tools utilized.

Programming Details:
For optimal results, ensure lengths (L1 and L2) on the part are equal to or greater than the radius (R). Bends can also be created by positioning the cursor at the flange end, where modifications can be made easily through a pop-up properties window.

The DELEM DA-69T Product Drawing tool enables precise, straightforward product design, optimizing the efficiency and accuracy of the bending process.

Large radius: Bumping

If a tool with large radius is not available, the bumping method can be chosen. With this method, a large radius in a product is obtained by a series of slight bends in succession.

First you can choose the Angle Definition. The available definitions are:

• The default angle is the angle which could be programmed as standard.

• The central angle is the supplement of the default angle (i.e. 180 degrees – default angle).

To apply the bumping method, the following parameters must be programmed:

1. Central Angle: Set the angle to achieve the desired bend.
2. Radius: Input the target radius for accurate product shape.
3. Number of Segments: Divide the radius into segments, with the number of bends equal to segments plus one. More segments result in smoother, more precise bends but need a smaller V-die opening.
4. Equal Bumping-Segments: Choose between equal or variable segment sizes. Enabling equal sizes helps in selecting appropriate dies. If disabled, the system can recalculate if there’s a V-die size issue.

To implement a bumping bend, program a standard angle first. Use the Properties function to select Bumping as Bend Type, then input the radius, segments, and segment size preference. The system will then draw the radius and inform you of the smallest segment length, guiding die choice.

Hem bends

To initiate a hem bend, you can start by setting a flange with a prebend angle. By positioning the cursor on the desired bend and selecting ‘Properties’, a pop-up window allows you to customize the bend properties.

For creating a hem bend, position the cursor at the flange end and select ‘Properties’ to access a pop-up with additional settings. Key configurable attributes include:

Prebend Angle: Adjust the sharp pre-bend angle to suit project needs, with a default of 30 degrees.

Hem Opening: This parameter defines the distance between flanges during hemming. It influences beam position and uses the ‘Default Hem Opening’ value from settings by default.

Side Length: Define the flange length needing hemming for precise specifications.

Using DELEM DA-69T Product Drawing ensures accuracy and flexibility, improving design quality and production efficiency.

Prebend, two stage bending

The DELEM DA-69T Product Drawing enhances press brake operations by allowing precise bending in two stages. This is achieved by incorporating a prebend into the sequence, which is easily set within any bend’s properties. By programming a prebend, operators can split the bending into a prebend and a final bend. This not only refines the bend but also provides better control and precision.

Insert temporary bend

The DELEM DA-69T Product Drawing feature enhances your bending process by allowing you to insert temporary bends. This is particularly useful for complex sequences where collision prevention is necessary. By adding a bend that is later flattened, operators can efficiently manage intricate operations without interference.

When inserting a bend in the DELEM DA-69T, you can choose to make it temporary. This integrates with the prebend function to ensure all necessary angles are considered in the sequence calculation.

Exploring Bend Labels and Markers

Bend labels (DA-6xTe only)

The DELEM DA-69T Product Drawing feature boosts precision in managing bend sequences and graphical displays. Among its modes—Bend Sequence, Auto-mode, and Drawing—the Drawing mode uniquely enhances visualization with bend labels.

Bend labels automatically assign each bend line a distinct alphabetical identifier, streamlining their identification during sequence adjustments or production. This feature ensures operators maintain control over the product.

To enable bend labels, simply tap the bend label view button, prompting labels to appear on each bend line. This simplifies distinguishing between multiple bends and prevents errors.

Surface or Bend Line Markers

The DELEM DA-69T Product Drawing functionality enhances the clarity and accuracy of your designs with its effective marker feature. This tool allows for easy marking of specific surfaces and bendlines, improving recognition and streamlining production.

• The configuration can vary: changing the left, right, or both ends.

Flexibility and Constraints:

• Some sides can be extended or shrunk in both directions, especially when both ends are free.
• Constraints exist when both ends of a side align with the direction of a bend line, restricting changes.
• Examples:
  • Side 1: Freely extendable or shrinkable in both directions.
  • Side 2: Only the free end, not involved with a bend line, can be adjusted.
  • Side 3 to 6: Varying levels of modifiability based on the structural setup.
