Bearing is an important component in contemporary mechanical equipment, mainly used to determine the supporting or guiding role of the rotating shaft and other parts. The traditional manufacturing process of bearings is quite complicated. In real processing, the steps can sometimes reach as many as 70 steps, especially the precision requirements of heat treatment, forging and grinding are very strict. However, if 3D printing technology and Sanyu AD modeling software are used, the model production process of the bearing can be completed in as little as an hour, which greatly simplifies the production steps, reduces the cost of materials, and reduces the error rate.

Before 3D printing, you must rely on the front-end modeling software to design and create a 3D data model. Common 3D CAD design software includes foreign Solidworks, NX, and domestic Zhongwang 3D. Since Zhongwang 3D has a flexible free-form surface hybrid modeling function, it can meet the needs of enterprises for accurate design, and in the 2013 version, the 'direct output to 3D printer' (Print3D) has been added, allowing users to easily and quickly interact with 3D printers. Printer interaction, fast printing. The bearing rendering is completed as shown in the upper left picture, that is, the important front-end 3D CAD data model has been created, and then 3D printing will be realized.

Because 3D printing is a rapid prototyping technology, The premise of using adhesive materials such as powdered metal or plastic to construct objects by layer-by-layer printing must be based on digital model files. Therefore, it is necessary to create a 3D CAD data model through the previous product modeling. Next, you can print the model with a 3D printer:

Step 1: Since the 3D printing file format is STL, first convert the designed model drawings to STL format using Zhongwang 3D output. Zhongwang 3D has A complete input and output data interface is specially designed for seamless integration with 3D printing software. Select the file '3D printing' button on the operation interface (as shown in the figure below) to automatically switch to the dedicated 3D printing software interface without manually converting the STL format. 3D printing programming work.

Step 2: Input the bearing STL file into the printing management software corresponding to the 3D printer. Since the 3D printer has a maximum printing size, it can be printed according to the printing range of the printer. Adjust the position, orientation, scale and printing properties of the product.

Objet's 3D printers can use the Objet Studio print management software to adjust the product before output and specify the printing material. After the relevant settings are completed, it can be output to the 3D printer for actual product printing.

You can adjust the scale of the parts according to actual needs. Adjust the product placement position and place it within the printing table.

Specify the corresponding printing materials.

Step 3: Realize through the output printer function Printing operation.

From the above picture, we can know that the time required for printing processing is 04:17, the product weight is 166g, the supporting weight is 85g, and the total weight of the required materials is 251g. Printing. As follows:

Through 3D printing technology, we can quickly design, test and other work for new products. g Don't for complex products, it can better reflect its rapid prototyping and cost saving Advantages. Zhongwang 3D can assist in preliminary modeling and design to meet the precise use needs of manufacturing enterprises. More and more practical applications have proved that Zhongwang 3D's CAD/CAM integrated solution can easily meet customer needs, So as to realize the best way from design to processing.
