Oil quenching spring steel wire heat treatment spray quenching device and process thereof

Abstract

The invention relates to the technical field of oil quenching spring steel wires, in particular to an oil quenching spring steel wire heat treatment spray quenching device and a process thereof. The device comprises a worktable, a main spray quenching device and an auxiliary spray quenching device; a guide device is arranged at one end of the worktable; the main spray quenching device and the auxiliary spray quenching device are arranged on the worktable in sequence; an inner oil tank is formed in the worktable; multiple oil return ports are formed in the lower end of the worktable; the oil return ports communicate with the inner oil tank; an oil return pipe and a main oil inlet pipe are arranged beside the worktable; and the oil return pipe communicates with the oil return ports through pipes. The device has the following beneficial effects: the oil temperature can be lowered after quenching, so that the lampblack generation is reduced, and the consumption of quenching oil is reduced;and the advantages of convenience to operate and adjust, simple process control, energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of oil-quenched spring steel wire, in particular to an oil-quenched spring steel wire heat treatment spray quenching device and a process thereof. Background technique [0002] Oil quenching spring steel wire heat treatment line, as the heat treatment equipment in the process of spring steel wire processing, is particularly important to the quality of spring steel wire. At present, the suspension spring steel wires for cars are developing in the direction of high stress, high yield ratio, low residual stress and high strip performance. In addition, at present, higher standards and requirements are put forward for the production and environmental protection of enterprises, but the existing spring steel wire heat treatment spray quenching device consumes a lot of oil, and the large amount of volatilization and vaporization of quenching oil will also cause great impact on the environment. For the above problem...
