Detailed description of the invention
Below by specific embodiment, the outer spill ring forgeable piece tool of engineering machinery of the present invention is described in further detail.
The outer spill ring forgeable piece tool of engineering machinery, comprise upper punch 1, low punch 2 and main mould 3, the structure of described upper punch 1 as shown in Figure 1, coaxially arrange form an entirety by falling frustoconical section 11 and shell portion 12 successively from top to bottom, the minor diameter of frustoconical section 11 of falling equals the diameter of shell portion 12, the structure of described low punch 2 as shown in Figure 2, is truncated cone, the diameter of the shell portion 12 of upper punch 1 is not less than the minor diameter of the truncated cone of low punch 2, wherein equals the minor diameter of the truncated cone of low punch 2 for the best with the diameter of the shell portion 12 of upper punch 1, the structure of described main mould 3 as shown in Figure 3, from top to bottom successively by upper shell portion 31, frustoconical section 32, mediate cylindrical section 33 and lower shell portion 34 coaxially arrange formation entirety, the diameter wherein going up shell portion 31 equals the minor diameter of frustoconical section 32, the major diameter of frustoconical section 32 equals the diameter of mediate cylindrical section 33, the diameter of mediate cylindrical section 33 is greater than the diameter of lower shell portion 34, on described main mould 3, the diameter of shell portion 31 equals the diameter of lower shell portion 34, transition position between the upper shell portion 31 of described main mould 3 and frustoconical section 32 is fillet, transition position between described frustoconical section 32 and mediate cylindrical section 33 is fillet, transition position between described mediate cylindrical section 33 and lower shell portion 34 is fillet.
Operation principle of the present invention is: when using the outer spill ring forgeable piece tool of above-mentioned engineering machinery to be rolled, first low punch 2 is adopted blank material to be gone out the lower opening of a cone shape, then upper punch 1 is adopted to carry out upper punching thus obtained structure blank material 4 as shown in Figure 4, the outer wall finally outer wall of blank material 4 being pressed on main mould 3 carries out rolling ring, in the outer wall of blank material 4, annular concave step 51 is extruded, final obtained structure ring forging 5 as shown in Figure 5 by the frustoconical section 32 of main mould 3 and mediate cylindrical section 33.Wherein, when adopting main mould 3 to carry out rolling ring, middle and upper part due to main mould 3 is frustoconical section 32, blank is facilitated to be engaged and the demoulding with main mould, can make the rolling of rolled piece energy steadily, to fill type complete, and then decreases the scrappage of ring forging 5, saved material, save the energy and man-hour, improve operating efficiency.
The invention has the beneficial effects as follows: the outer spill ring forgeable piece tool of above-mentioned engineering machinery, structure is simple, easy to use.Adopt the outer spill ring forgeable piece tool of above-mentioned engineering machinery, the outer spill ring forgeable piece tool of engineering machinery can be processed simply, and can raw-material wasting phenomenon be reduced, thus reduce production cost.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
