Abstract

The invention belongs to the field of machine manufacturing and particularly relates to a preparing method for a 1000 MPa level heat treatment wheel. The technical scheme includes the following stepsthat firstly, a steel material is selected, wherein the steel material comprises chemical components including, by mass percent, 0.15%-0.20% of C, 0.7%-1.17% of Si, 1.2%-2.2% of Mn, 0.02%-0.06% of Al,0.015%-0.02% of P and the balance Fe and inevitable impurities; secondly, the selected steel material is used for manufacturing a wheel spoke with the qualified size and a wheel rim with the qualified size through a conventional production technology; the wheel spoke and the wheel rim are combined into a wheel with the qualified size through the conventional production technology; and thirdly, heat treatment is conducted on the wheel, wherein the heat treatment process includes that the wheel is firstly heated to 790 DEG C to 810 DEG C and discharged out of a furnace, when the wheel is cooledto 780 DEG C to 786 DEG C in air, the wheel is put into a salt bath to be cooled and quenched to 235 DEG C to 245 DEG C and then heated to 320 DEG C to 340 DEG C, and the wheel is cooled to be below100 DEG C in air and then subjected to washing. The shape size of the manufactured wheel meets the standard requirement, and the overall physical performance is optimized.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a method for preparing a 1000MPa grade heat-treated wheel. Background technique [0002] When making steel wheels, the conventional production process of wheel spokes includes: blanking, punching center holes and bolt holes, spinning, blowing holes, expanding bolt holes, and turning; the conventional production processes of wheel rims include: rolling, flashing Welding, rolling, end cutting, compound rounding, flaring, rolling, expanding and shaping, punching valve holes; wheel spokes and wheel rims are made into wheels through synthetic welding processes. [0003] At present, the high-strength materials used in the traditional manufacturing process of steel wheels generally use materials with a tensile strength of about 400 MPa, and the highest individual ones are only about 700 MPa. The main reasons are: first, the processing capacity of the equipment is ins...
