When it comes to creating precise and efficient metalworking solutions, the DELEM DA-58T Product Drawing process is a critical component. If you’re searching for a comprehensive understanding of the steps involved in the DELEM DA-58T Product Drawing, you’re in the right place.

In this article, I’ll guide you through the key steps you need to follow to master the DELEM DA-58T Product Drawing, ensuring you can harness its full potential. Whether you’re new to this technology or looking to refine your skills, this guide will provide the insights you need to execute effective product drawings with the DELEM DA-58T system.

General product properties

If you need to start a new DELEM DA-58T Product Drawing, select New Product in the product library.

When initiating a new product drawing, a screen with general product properties will appear. These general data properties should be set before commencing with the DELEM DA-58T Product Drawing.

Product ID is essential as it uniquely identifies a product program, with a limit of 25 characters. It can contain both letters and numbers. The Product Description, similarly, can have up to 25 characters and describe the program’s purpose.

If you enter an existing Product ID, a warning will prompt you to decide whether to overwrite the existing product. Choosing ‘yes’ erases the previous product, whereas ‘no’ requires a new ID entry.

Key parameters include:

• Thickness: Specify the sheet’s thickness.
• Material: Select from four pre-programmed material types. Refer to Settings to program additional materials and select the required material to activate it.
• Bending Length: The Z-length of the sheet.
• Dimensions: Choose between outside (A) or inside (B) dimensions for new sides or surfaces. The default is dictated by the Settings mode parameter Default Dimensions.
• Radius: After selecting tools in the tool setup, the product radius recalculates, but you can choose to ‘use programmed’ if you prefer no recalculation.
• Bend Allowance: Opt for ‘use calculated’ or ‘use programmed’ based on the Delem formula or bend allowance table.

To change the active directory, select ‘Save as’ and ‘Change directory’. The current DELEM DA-58T Product Drawing will be automatically copied to the new directory.

2D product drawing

After entering the general product data the drawing screen appears.

In DELEM DA-58T Product Drawing, you begin by locating the necessary information such as product ID, description, and dimensions in the upper information row. You can then create the product profile using the ‘sketch’ mode, allowing you to quickly draft the design by tapping with your fingers. Once the preliminary sketch is ready, you enter the precise dimensions and other relevant values using the keyboard.

Direct input of bend angles and side lengths is also possible via the keyboard and the Enter button. This process continues until the desired product profile is achieved. If you need to make adjustments, you can modify product data under Product Properties, and changes to angles and lines can be made by selecting Properties.

The currently active element (line or angle) is highlighted. In a product drawing you can program up to a maximum of 99 bends per product (graphical programming).

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

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 for the DELEM DA-58T Product Drawing, 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 projection function is a useful aid for drawing diagonal lines between points without having to compute the precise side length. When a line is selected, simply enter a horizontal or vertical projection distance and press Enter. The required line length is computed and applied to the selected segment.

L is the normal entered line length, V is the vertical projected line length, and H is the horizontal projected line length.

It will be noted on the screen if the projection is not possible.

Precision selection

When the drawing cursor is on a line segment in the DELEM DA-58T Product Drawing, you can select the level of precision for the line by entering the properties and navigating to the parameter Precision.

Precision

• Normal: Achieve normal accuracy for this segment.
• High: During bend sequence computation, the back gauge stop position will be selected to obtain the highest possible precision for this line interval.
• Closing Dimension: During bend sequence computation, the back gauge stop position will be chosen to ensure the resulting tolerances within this line interval.

A line interval marked with an open circle should ideally be directly placed between the back stop and the center of the die.

Notes: Specifying line intervals with high precision and closing dimensions in the DELEM DA-58T Product Drawing may lead to longer production times. The precision parameter will take precedence over the “front extend ratio” if it is set to “comply if possible”.

Bend properties

Air bend

Drawing a product graphically within the DELEM DA-58T Product Drawing process involves programming elements like line length and angle value until the product reaches its desired shape. The bends present in the product come with standard or specific properties that can be adjusted by selecting a bend and configuring its properties.

• Bend Type
  • Air Bend: Normal bend with a specified angle and preferred radius.
  • Bumping: Used for creating a large radius in multiple airbending steps.
  • Hem Bend: Combines a pre-bend (standard air bend with a sharp angle) and hemming action using a specialized tool.
• Angle: This is the value to which the material is bent.

• Preferred Radius:This is the intended radius that is programmed, starting with the product’s thickness as the initial value. A larger radius may require specific tools.

• Computed Radius: The radius resulting from the control settings, influenced by the tools used during the bending process. A special punch might be necessary for large radii, or alternatively, the bumping method can be employed. Ensure the radius does not exceed adjacent side lengths.

For programming line lengths connected to a radius bend, lengths L1 and L2 should be equal to or greater than radius R.

You can also create a bend by placing the cursor at the flange end where the bend is needed and selecting Properties. This will prompt a pop-up window with an additional parameter to complete.

Large radius: Bumping

If a tool with a large radius is not available, the bumping method in DELEM DA-58T Product Drawing can be employed. This method achieves a large radius by using a series of slight bends in succession.

First, choose the Angle Definition, such as the default angle or the central angle (180 degrees minus the default angle).

To apply the bumping method for DELEM DA-58T Product Drawing, program these parameters:

• Central angle: The supplement of the angle value to bend.
• Radius: Program the intended radius. Initially, the product thickness is used.
• Number of segments: The radius is divided into segments. The bends equal the number of segments plus one. More segments result in tighter tolerance but require a smaller V-die opening.
• Equal bumping-segments: This parameter decides segment size. When enabled, all segments are equal; when disabled, the first and last segments are half-sized for better results, but this may complicate die selection. If issues arise, users can opt for a recalculation with equal segments.

To program such a bend, start with a standard angle with adjacent sides. Then, go back to the angle, select Properties, and choose Bumping as the Bend Type. You’ll need to input the radius, number of segments, and whether to use equal segment sizes. Once these are set, the radius appears in the DELEM DA-58T Product Drawing, and you’ll receive a message about the smallest segment length, impacting the die selection.

Hem bends

When utilizing the DELEM DA-58T Product Drawing to create a profile with a hem bend, start by setting a flange with a prebend angle. Place the cursor on the bend and select Properties to adjust settings in the pop-up window.

Another option is to position the cursor at the flange end where the hem bend is desired, select properties, and an extra parameter will appear for customization.

Bend properties:

• Prebend angle: Typically a sharp angle, with a default of 30 degrees, adjustable to suit practical needs.
• Hem opening: Defines the opening between flanges, crucial for calculating beam position in hemming, with a default set by the Default Hem Opening parameter in Settings.

Side properties:

• Side length: The length of the flange to be hemmed.
