The application of SolidWorks sheet metal function in the unfolding of bending parts


the blank unfolding size of regular V-shaped and U-shaped bending parts can be calculated manually according to the principle of constant neutral layer length. For the bending parts with complex shapes and holes on the flange, it will be difficult to calculate the expansion size and hole location size by hand. Figure 1 is the part drawing of the left support - engine rear suspension beam, made of 16MnL, with holes on the flange and irregular shape. Next, take it as an example to introduce the application process in detail

1. Generate part entity

1.1 start

solidworks2001, click file → new, select template → part in the pop-up dialog box, and then click OK

1.2 make the matrix

select the forward-looking datum, click Insert → sketch command to enter sketch drawing. Click Insert → boss → stretch, write the definition in the PropertyManager of durability: more than 100000 words (width r0.8mm, pressure 250g) on the PL screen, and finally generate the matrix stretch, as shown in Figure 2

Figure 2 Matrix stretching

1.3 making 88 ° inclined plane

select the upper surface of the substrate as the datum plane, and click the insert → sketch command to enter sketch drawing. Click Insert → cut → stretch, define in PropertyManager, OK, and complete the 88 ° slope

1.4 shell out to make the thickness of parts equal

click Insert → feature → shell extraction, define in PropertyManager, select the face to be removed, confirm, and complete shell extraction, as shown in Figure 3

2. Convert parts to sheet metal

click Insert → formulate the medium and long-term energy technology development strategy and development plan to 2020 → sheet metal → bend, define in PropertyManager, confirm, and get the sheet metal parts, as shown in Figure 4 and figure 5. The K-factor is directly selected in Table 1 or calculated by interpolation method

3, generate hole features

select two flange planes and webs as datum planes respectively, click Insert → sketch command to enter sketch drawing. Click Insert → cut → stretch, define in PropertyManager, confirm, and complete the hole feature, as shown in Figure 6

Figure 6 generate hole feature

4. Generate sheet metal part into drawing

4.1 click file → new, select template → drawing in the pop-up dialog box, and then click OK

4.2 click window → tile vertically, and list the drawing file and sheet metal file in the window, as shown in Figure 7

Figure 7 vertical tiling window

4.3 click Insert → engineering view → named view, select the flat pattern in PropertyManager, move the view to the appropriate position within the drawing range, and complete the engineering drawing, as shown in Figure 8

5. Detailed drawing

engineering drawing printing equipment is usually established in layers, and dimensions and notes need to be added to meet practical requirements, as shown in Figure 9

Figure 9 detailed engineering drawing

6. Conclusion

the expansion size provided by the engineering drawing has been verified by the profiler, and the parts meet the requirements of the drawing. This shows that it is a feasible method to use SolidWorks sheet metal function to obtain the unfolding size of bending parts. (end)
