Quenching die for outer ring of double-row self-aligning roller bearing made of large-sized carburized steel

Abstract

The invention discloses a quenching die for an outer ring of a double-row self-aligning roller bearing made of large-sized carburized steel. The quenching die structurally comprises a workpiece, a quenching pipe, a heat conducting joint, mounting holes, smooth surface components, a die base, a mounting plate, a cooling joint and a conversion mechanism. The bottom of the conversion mechanism is mounted inside the die base in an embedded manner. The die base is of a rectangular structure. The mounting plate is arranged at the bottom of the die base. According to the quenching die for the outer ring of the double-row self-aligning roller bearing made of the large-sized carburized steel, the conversion mechanism drives the workpiece to be rotated and lifted so as to cooperate with the quenching pipe to perform all aspects of quenching treatment, and the cooling method adopts cooling components to perform uniform spraying in an inner cavity of the workpiece, so that the residual of impurities, caused by direct flushing with the surface, in the water can be avoided, the uniform cooling effect is retained, the automatic rotation and lifting are completed under the driving of a liquid transfer mechanism, and the manual process step is saved.

Description

Technical field [0001] The invention relates to the field of molds, in particular to a large-size carburizing steel double-row spherical roller bearing outer ring quenching mold. Background technique [0002] Double row spherical roller bearing is a kind of bearing with self-aligning function. It is not easily limited by the angle error of the shaft and the outer ring of the bearing. It is suitable for installing various error angle shafts or equipment that disturbs the crankshaft. It is used in paper machinery, Reducers and railway vehicles are widely used. The materials for double-row spherical roller bearings are mostly made of carburized steel. Generally, the outer ring needs to be quenched by a high-frequency machine after forming, which greatly improves The rigidity, hardness, wear resistance, fatigue strength and toughness of steel. The existing technologies on the market have such problems in the use process: [0003] The current quenching mold is to support and fix the d...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of this invention is to provide a large-size carburizing steel double-row self-aligning roller bearing outer ring quenching mold to solve the problem that the current quenching mold supports the double-row self-aligning roller bearing. Fixed, and then used with a high-frequency machine, it only serves as a fixed function. During the heating process, the staff needs to manually complete a series of processing procedures such as lifting, rotating, and smoothing, which cannot ensure the quality of quenching. Direct cooling is likely to cause more impurities on the surface of the outer ring, and the surface cannot be kept smooth, which needs to be optimized
