Problems solved by technology

[0002] At present, when manufacturing bearing housings, experienced technicians need to repeatedly adjust on high-precision machine tools to process qualified parts, which has low efficiency, large human factors, and high cost.
The smelting of the bearing seat is carried out in a water-cooled copper pincer crucible vacuum arc melting button furnace. The melting process of this furnace is complicated and requires repeated vacuuming and repeated turning for melting. The smelting time is long, and at the same time, there is pollution of the tungsten alloy electrode to the alloy, the alloy composition and structure uniformity are low, only small-volume metals can be smelted, and the application range is small

Abstract

The invention discloses a manufacturing process of a bearing seat. The manufacturing process of the bearing seat includes following steps: casting; smelting; preparing ramming mix, the ramming mix comprises fire clay, quartz sand and water; filling a cupola furnace with the ramming mix to make a lined furnace, and arranging a wind eye on the lined furnace; adjusting temperature of the cupola furnace to 500-700 DEG C to dry the lined furnace; making a fire in the cupola furnace, and allowing temperature to rise to 900 DEG C; filling the pond lined furnace with materials, and the materials comprise coal coke, novel iron, old iron, waste steel, silicon, manganese and iron; adjusting the temperature of the cupola furnace to 900-1200 DEG C, and smelting the materials in the cupola furnace; opening the cupola furnace to discharge melted iron, adding copper, chromium, molybdenum in the melted iron which is at 1400-1450 DEG C when the melted iron is discharged; casting the melted iron into a cavity of a mould by the aid of a crane ladle for casting; and unpacking and delivering. The manufacturing process of the bearing seat has the advantages of simple manufacturing process and short manufacturing cycle.
