Air-cooled continuous heat treatment quenching furnace

Abstract

The invention discloses an air-cooled continuous heat treatment quenching furnace. The air-cooled continuous heat treatment quenching furnace comprises a U-shaped conveying belt, a heating and heat preservation section, a feeding conveying belt, a discharging conveying belt and a quenching section. The starting end and the tail end of the U-shaped conveying belt are both horizontally arranged. The feeding conveying belt and the discharging conveying belt are both linear conveying belts. The discharging end of the feeding conveying belt abuts against the starting end of the U-shaped conveying belt. The feeding end of the discharging conveying belt abuts against the tail end of the U-shaped conveying belt. The heating and heat preservation section is arranged in the middle of the feeding conveying belt. The quenching section is arranged in the middle of the discharging conveying belt. The problems that in the prior art, although a closed vacuum quenching furnace can achieve the quenching effect of a to-be-quenched part, continuous production cannot be achieved, and although a continuous quenching furnace can achieve continuous production of the quenching process, due to the fact that a heated workpiece is slowly conveyed to a rear section cooling section through a mesh belt, the quenching effect is poor are solved.

Description

technical field [0001] The invention belongs to the field of heat treatment processing equipment, and relates to a heat treatment quenching furnace structure, in particular to an air-cooled continuous heat treatment quenching furnace, which realizes rapid cooling and quenching of quenched parts and continuous production function, and solves the problem of existing Although the airtight vacuum quenching furnace in the technology can realize the rapid cooling effect of the workpiece to be quenched, it cannot realize continuous production. Although the continuous quenching furnace can realize the continuous production of the quenching process, the workpiece is slowly sent to the rear cooling section through the mesh belt after heating. Causes the problem that the rapid cooling effect is not good. Background technique [0002] Today's heat treatment furnace equipment can be roughly divided into the following two types: one is a closed vacuum quenching furnace, and the other is a...
