Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0041] A method for forging a wheel forged by secondary pressurization molten soup, according to the following steps:

[0042] (1) Raw material smelting: The raw material is smelted in the melting furnace, and the molten soup required for forging is obtained after the raw material is smelted;

[0043] ⑵Insulation storage: The molten soup is stored in an open insulation furnace, and the temperature is kept at 760°C;

[0044] (3) Melt soup degassing: Infinite internal circulation degassing equipment is installed in the lower part of the holding furnace to degas the molten soup in the holding furnace;

[0045] The positions of the smelting furnace and the holding furnace are set from high to low, and t...

Abstract

The invention relates to a forging method and a forging device of a twice forcing molten forging wheel. The forging method of the twice forcing molten forging wheel is conducted circularly by the following steps: (1) materials smelting; (2) heat preservation deposit; (3) molten soup degassing; (4) the molten soup being injected into a lower die; (5) main piston forcing and pressure maintaining; (6) auxiliary piston forcing and pressure maintaining; (7) die sinking; (8) product transfer and deposit; (9) die cooling. Product quality is improved and molten soup dosage is reduced, and twice forcing is conducted to further improve inner structure refined grain of metals, and therefore the forging method and the forging device of the twice forcing molten forging wheel has the advantages of improving product mechanical property, tensile property and other overall properties, shortening product production time, increasing output, improving production efficiency and ex-factory percent of pass of products.

Description

technical field [0001] The invention belongs to the field of wheel forging, in particular to a forging method and equipment for forging a wheel by secondary pressurized molten soup. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. Casting types include: Gravity die casting, Low pressure die casting and Vacuum die casting. These casting methods tend to cause shrinkage cavity and gas ingress due to the slow solidification speed of the molten soup during production. The situation occurs, resulting in a produ...
