Create Bolting Sets (3-D)

3-D Standard > Standard Parts > New bolting

An expert system for mechanics is available for fitting complete boltings. This system supports you during solving of standard problems, such as the design of a bolting. You can use a catalogue system to select bolts, washers, nuts, bores, countersinks and threads, thus constructing your individual bolting. Corresponding plausibility checks prevent inadmissible specifications. Only matching bolting elements according to DIN will be suggested, i.e. unsuitable elements will be excluded right from the start.

In addition, you can define the arrangement of the bolting - as an individual bolt or on a pitch circle. You can specify the values for the minimum bolt projection length and the minimum bolt depth individually.The advantages of this expert system can be seen especially when changing boltings that have already been fitted. For example, you can start the input dialogue directly by selecting the desired bolting and can choose, say, another thread runout.

The Bolting dialogue window, which is displayed when you call the New boltings function, is used to construct boltings and set further options. On relevant tabs in this dialogue window, you can

• specify the components of the bolting,
• define further options, such as the bolt projection length, or load/create new bolting configurations, and
• create and process bolting selection templates.

The dialogue for the fitting of boltings appears as soon as you click OK to end one of the tabs.

Do not forget to save your configurations regularly.

'Parts' Tab

You use the Parts tab to access all available bolts, washers, nuts, bores, countersinks and threads of which the bolting can consist.

The Parts tab

To select a part for the bolting, activate the relevant checkbox , and choose the desired sizes in the right-hand column.

To select another element, e.g. another bolt, simply click the relevant graphic symbol. HiCAD then displays an overview of all available Standard Parts and Standard Processings. Choose the bolt you want and click OK to exit the selection window.

After choosing a configuration file on the Options tab, HiCAD will check upon selection of a bolt whether the file contains any configurations for this bolt. If this is the case, you can select the desired configuration from the list box at the top of the dialogue window.

Please note:

• If the composition of the bolting is a non-standard composition, this will be indicated by a message at the bottom of the dialogue window.
• Boltings do not need to contain bores, i.e. you can also insert boltings into existing bores.
• Instead of bores and countersinks according to DIN, you can also use slots or free bores in boltings. To do this, click the icon and then enter the required data.

Settings: Bores

'Options' Tab

The Options tab)

Minimum projecting length of bolt / Minimum screw-in length

HiCAD normally determines the minimum bolt projection length and the minimum bolt depth automatically. However, the Options tab allows you to change the default setting used .

• Lmin is the product of gradient D and any factor.
• Umin is the product of bolt diameter P and any factor.

Enter the factors to determine Lmin and Umin.

Configuration file

The composition of a bolting, i.e. the selection of its individual elements, can be saved in configuration files, which enables a later re-use. Via the Configuration File list box you can select the file the configuration of which you want to use, or to which you want to add further configurations.

To create a new configuration file, enter the name of the new file in the Configuration File input field, and click Create.

To load a configuration file, simply select its name from the list box.

The editing of a configuration file, i.e. the creation and modifying of configurations, takes place on the Settings tab.

The configuration files are saved to the HiCAD directory Kataloge\sys\configs.

'Settings' Tab

You can use this tab to configure frequently used bolt connections and save them to a file that you select from the list box on the Options tab.

The Settings tab

To define a bolt connection, proceed as follows:

1. Select the bolt type. To do so, click the bolt symbol, e.g. . Select the bolt type and then the desired standard series.
2. Click OK to exit the selection window. The bolt symbol in the Bolting window is automatically updated.
3. Select the connection elements. To do so, click the corresponding symbol, e.g. or rectangle Select the desired type and then the standard series.
4. Click OK to exit the selection window. The selected connection element is displayed as a symbol and the corresponding checkbox automatically updated.
5. Before saving the configuration, specify whether you want the settings to be saved as basic settings by activating or deactivating the Use default settings checkbox. If the checkbox is active when a bolt connection is saved, the connection elements assigned to this type are then displayed automatically on the Parts tab when this bolt type is loaded.
6. To save the configuration, enter its name in the input field at the top of the window and click the Save icon.

If not all available types are displayed during selection of bolts or connection elements, you can use the Add new ... function in the corresponding row. This function enables you to enhance the selection lists for bolts and connection elements. In this way you can add, for example, fasteners from the Factory standards > User-defined fasteners catalogue, such as anchors or dowels.
