Embodiment 1
[0062] like figure 1 The flat coil shown, which is rolled from strip, comprises a plurality of coil layers 1 . The cross-section of the coil layer 1 is flat, and the outer contour is ring-shaped. The coil layer 1 is coiled around the longitudinal extension line to form a stacked shape in the longitudinal direction, so that the outer contour of the flat coil is figure 1 The cylinder shown is helical. In the first embodiment, the coil layer 1 has a width of 20mm and a thickness of 0.25mm.
Embodiment 2
[0064] like figure 2 , 3 As shown, in this embodiment 2, a rolling section 35 is defined on the generatrix of the conventional cone 2 of the tapered roll, and the first and last ends of the rolling section 35 are the rolling section start 5 and the rolling section end 6 respectively. A rolling section 3 is processed in the rolling section 35, and the bottom length of the rolling section is S 2 and the bottom length of rolling section S 1 equal. The ends of the tapered rollers are connected to the extension shaft 4 . In this embodiment 2, the cone angle α of the conventional cone 2 is 65°. The outer contour surface of the rolling section 3 is an arc surface, and the arc surface is also the rolling surface of the rolling section 3 . According to the outer ring diameter D of the flat coil produced 1 (The value is the outer radius R of the line of the flat coil 1 Twice of), inner ring diameter D 2 (The value is the inner radius R of the wire of the flat coil 2 Twice of),...
Embodiment 3
[0068] like Figure 4 , 5, 6, and 7, the difference between this embodiment 3 and embodiment 2 is that the outer contour surface of the rolling part 3 is a polyline surface, that is, the rolling part 3 is connected by a plurality of cones with different cone angles constitute. Meanwhile, the outer contour surface of the rolling section 3 is also the rolling surface of the rolling section 3 . According to the outer ring diameter D of the flat coil produced 1 (The value is the outer radius R of the line of the flat coil 1 Twice of), inner ring diameter D 2 (The value is the inner radius R of the wire of the flat coil 2 Twice of), inner ring thickness H 1 (that is, the thickness H of the wire of the target flat coil), the thickness H of the outer ring 2 , width-to-thickness ratio and other parameters, the rolling section in Example 3 can be composed of 2 to 4 cones with different cone angles, and its specific parameters are shown in Table 2, where the rolling section heigh...
