Abstract
The invention provides a die pressing quenching device of a big gear ring. The die pressing quenching device comprises a sliding table, an upper die assembly, a lower die assembly, a core shaft for placing a gear ring and a quenching liquid assembly, wherein the upper die assembly comprises an upper die seat, a wedge block and a quenching liquid pressing cover; the lower die assembly comprises a lower template and a lower die seat; the lower template is provided with an annular groove; through holes, which are distributed in the peripheral direction, are further formed in the lower template; the lower die seat is provided with an annular cavity; the annular cavity is communicated with the through holes. The quenching liquid assembly comprises a quenching liquid tank, a water pipe, a centrifugal pump and a solenoid valve; the quenching liquid tank is communicated with the annular cavity of the lower die seat through the water pipe; the water pipe is provided with the centrifugal pump and the solenoid valve. The die pressing quenching device provided by the invention has the beneficial effects that upper and lower end faces of the gear ring are tightly pressed through the upper die seat and the lower template and deformation of the end faces of the gear ring is limited; the outer circle of the gear ring is tightly pressed through the wedge block mounted on the upper die seat andthe deformation of the outer circle of the gear ring is limited, so that the middle part of the gear ring is prevented from being lumped in a quenching process, and the quenching efficiency and quenching quality of workpieces are improved.
Description
technical field [0001] The invention belongs to the technical field of press quenching, and in particular relates to a press quenching device for a large ring gear. Background technique [0002] Molding quenching, also known as pressure quenching, is to heat annular thin-walled parts (such as gears, ring gears, bearing rings, etc.) At the same time, the parts are controlled to maintain a certain size and shape, that is, enough external force is used to offset the phase transition stress of the workpiece, so that the distortion of the parts is greatly reduced, thereby reducing or canceling the subsequent processes. [0003] High-precision parts, such as automotive spiral bevel gears, automotive synchronizer ring gears and high-quality bearing rings, often produce obvious deformation when quenched in an open fuel tank (free quenching). Pressure quenching is to use professional tools to apply external force at key points of the part to strictly limit the movement of the part, ...
