Technical Field

the invention relates to the field of engineering machinery, in particular to a hub casting method.

Background

The casting technology is one of the basic technologies of the modern mechanical manufacturing technology, and the metal component casting is to smelt metal into liquid metal which is poured into a cavity of a casting and cooled to obtain a workpiece with a preset shape. The hub is one of important parts of the rotary drilling rig; in the prior art, the wheel hub can break down after being used for a long time, for example, the wheel hub breaks down, once the wheel hub breaks down, the whole rotary drilling rig is potential safety hazard, and the existing wheel hub casting method has the defects of low utilization rate of raw materials, high production cost and insufficient structural strength.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides the hub casting method, which improves the utilization rate of steel quality, improves the casting precision, has high structural strength and improves the production efficiency.

in order to achieve the above object, the present invention provides a hub casting method, including the steps of:

s10: providing an upper die and a lower die of a hub with a sprue, wherein the upper die and the lower die can be matched to form a hub die cavity;

s20: uniformly coating a layer of release agent in the hub die cavity;

S30: fixedly connecting an upper die and a lower die, placing the upper die and the lower die into a sand box, laying bottom sand, fixing the upper die and the lower die in the sand box, placing the sand box on a vibration workbench, compacting the bottom sand, and vibrating while filling the sand to ensure that the filled sand is compact;

S40: pouring molten steel which is prepared in advance and has the temperature of 1350-1600 ℃ into a hub die cavity formed by an upper die and a lower die of a sand box along a pouring gate, and filling the whole hub die cavity;

S50: moving the sand box to a molding sand treatment position, naturally cooling to room temperature, and pouring out the molding sand and the hub product together;

s60: separating the upper die and the lower die, taking out the wheel hub blank, carrying out burr polishing treatment, and warehousing after the inspection is qualified.

Preferably, molten steel prepared in advance at a temperature of 1500 ℃ is poured into a hub cavity formed by an upper mold and a lower mold in a sand box along a pouring gate.

due to the adoption of the technical scheme, the invention has the following advantages: the casting method improves the utilization rate of steel, improves the casting precision, has high structural strength and improves the production efficiency.
