FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a frame; 2. a work table; 3. an elliptical die a; 4. an elliptical die b; 5. a hydraulic cylinder; 6. a limiting bracket; 7. a fixed seat; 7-1, limiting plate; 7-2. a support plate; 8. an inner liner ring; 9. an outer liner ring; 10. a slide rail.
Detailed Description
In order to make the objects, technical solutions and advantageous technical effects of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments;
in the drawings: an oval flange forming device comprises a workbench 2 arranged on a frame 1, wherein a movable oval pressing die a3 and a fixed oval pressing die b4 are arranged on the workbench 2; oval moulding-die a3 is connected with pneumatic cylinder 5, and oval moulding-die b4 right side is provided with spacing support 6, and fixing base 7 one end cooperatees with spacing support 6, and the other end is fixed on workstation 2.
Specifically, an inner lining ring 8 and an outer lining ring 9 are arranged between the elliptical die a3 and the elliptical die b 4; the surface of the flange is prevented from being damaged, the limiting supports 6 are symmetrically arranged in an L shape, the fixing seat 7 comprises a limiting plate 7-1 and a supporting plate 7-2 which are perpendicular to each other, the adjacent supporting plates 7-2 are arranged in parallel, and the supporting plate 7-2 and the limiting plate 7-1, and the supporting plate 7-2 and the workbench 2 are fixedly connected through welding. The inner lining ring 8 and the outer lining ring 9 are both elastic bodies. The slide rail 10 is arranged at the bottom of the elliptical die a3, so that the left and right movement of the elliptical die a is convenient to realize.
The utility model is implemented specifically as follows: starting a hydraulic cylinder to enable the elliptical pressing die a to move leftwards, placing the circular flange between the elliptical pressing die a and the elliptical pressing die b, positioning the outer lining ring outside the excircle of the circular flange, and positioning the inner lining ring in the inner hole of the circular flange; and starting the hydraulic cylinder again, driving the elliptical pressing die a to move rightwards by the hydraulic cylinder, applying force to the flange through the elliptical pressing die a until the circular flange is pressed into the elliptical flange, finishing the forming of the elliptical flange, retreating the hydraulic cylinder, and taking out the elliptical flange. The arrangement of the outer lining ring and the inner lining ring effectively protects the surface quality of the flange. The outer lining ring and the inner lining ring are made of elastomers, so that the rebound effect is good, and the rubber ring can be repeatedly used.
