Embodiment Construction

[0040] The present invention will be described in further detail below with reference to the drawings and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0041] A forging method for forging wheels with a secondary pressurized molten soup, according to the following steps:

[0042] ⑴ Raw material smelting: the raw materials are smelted in a smelting furnace, and the raw materials are smelted to obtain the molten stock required for forging;

[0043] ⑵Heat preservation: the molten soup is stored in an open holding furnace, and the temperature is kept at 760℃;

[0044] ⑶ Molten soup degassing: Infinite internal circulation degassing equipment is installed in the lower part of the holding furnace to circulate the molten soup in the holding furnace;

[0045] The position of the smelting furnace and the holding furnace is set from high to low, and the melting, degassing and ...

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 forging equipment for forging wheels with a secondary pressure melting soup. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate defects such as as-cast looseness during metal smelting 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 those of castings of the same material. Casting types include: Gravity die casting, Low pressure die casting, and Vacuum die casting. These casting methods are easy to cause shrinkage holes and gas ingress due to the slow solidification speed of molten bath in production. Circumstances occur, resulting in great differe...
