Attach Flanges to Surface (3-D SM)

Sheet Metal > Attach > Flange > Flanges to surface

For the attaching of a flange to a surface, the following 4 options are available:

• Flange to surface, with free bend zone
• Flanges to surface, bend zone closed
• Flanges to surface, with drainage area
• Flanges to surface, with circular cut-out

Lengths and parameters are specified in the same way for all 4 variants.

Length inputs

You can enter a value for the desired length. If you right-click the Length input field, a context menu with further options opens. You can then, for example, choose Pick distance to take the length directly from the drawing.

You have the following options to define the reference of the length:

Parameters

The bend angle can either be entered in the Angle input field or taken from the drawing by right-clicking the Angle input field and selecting Pick angle.

The Bend radius is located at the inner side of the bend zone. If you right-click the Bend radius input field you can directly pick the radius from the drawing. If the checkbox beside Bend radius is active , and the Use semi-finished product checkbox had also been activated in the Base sheet dialogue window, the radius will be loaded from the catalogue.

The Fitting mode refers to the processing of the connecting sheet. The following possibilities are available:

	Without shortening This mode leaves the connecting flange unchanged.	(1) Connecting flange (2) New flange
	Shorten, outer Shortens the connecting flange. The outer flange surfaces intersect in the plane of the front surface before the shortening.	(1) Connecting flange (2) New flange
	Shorten, inner Shortens the connecting flange. The inner flange surfaces intersect in the plane of the front surface before the shortening.	(1) Connecting flange (2) New flange
	Shorten, outer tangent Shortens the connecting flange. The outer surface of the bend zone contacts the plane of the front surface before the shortening.	(1) Connecting flange (2) New flange
	Shorten, inner tangent Shortens the connecting flange. The inner surface of the bend zone contacts the plane of the front surface before the shortening.	(1) Connecting flange (2) New flange

To obtain the blank (development) of the modelled Sheet Metal part, HiCAD offers you developments according to different calculation methods (allowance methods) that take the material-dependent length change of the workpiece during bending processes into account. For this, HiCAD also offers the common empirical, practice-oriented allowance methods.

The calculation methods are represented by prepared, exemplary system files. In practice, however, each user will store his own method(s) in this way. Before attaching the flange you can select the required system file.

Attach flanges to surface, bend zone free

Bend zone free

Use this function to attach flanges around a surface (base sheet). The selection of the top surface determines the direction of the new flanges.

(1) Top surface
(2) Flange with free bend zone

Attach flanges to surface, bend zone closed

Bend zone closed

Use this function to attach flanges with closed bend zones around a surface (base sheet). Sheets and bend zones will be lengthened up to the common intersection point of the inner edge. The selection of the top surface determines the direction of the new flanges. 

Attach flanges to surface, with drainage area

Drainage area

Use this function to attach flanges with drainage area around a surface (base sheet). The selection of the top surface determines the direction of the new flanges. 

(1) Top surface
(2) Flanges with drainage area

Attach flanges to surface, with circular cut-out

Circular

Use this function to attach flanges with a circular cut-out around a surface (base sheet). The selection of the top surface determines the direction of the new flanges.
