Embodiment 1

[0038] Such as figure 1 As shown, a transmission taper sleeve carburizing and quenching heat treatment method, the operator evenly fills the transmission taper sleeve to be processed on the special tooling for the transmission taper sleeve carburizing and quenching heat treatment, and ensures that the transmission taper sleeve The permeability of the filling is to ensure the effect of carburizing and quenching heat treatment. According to the process flow, the special tooling loaded with the transmission taper sleeve is transferred between the cleaning machine, preheating furnace, gas carburizing box-type multi-purpose furnace and tempering furnace to complete the carburizing and quenching heat treatment of the transmission taper sleeve, so as to improve the transmission. The hardness and wear resistance of the outer surface of the tapered sleeve can reduce the hardness of the inner hole of the transmission tapered sleeve, thereby achieving the purpose of improving the working...

Embodiment 2

[0050] Such as image 3 As shown, a tooling for carburizing and quenching heat treatment of a transmission taper sleeve, that is, a special tooling for carburizing and quenching heat treatment of a transmission taper sleeve, which includes a base 1 set in a square structure, and a plurality of The mounting holes 2 are staggered and opened on the base 1 to form a lattice structure. Mounting holes 2 can be vertically plugged with vertical rods 3, and there is a row of mounting holes 2 between each row of vertical rods 3, so as to achieve the purpose of improving the heat treatment permeability of the transmission taper sleeve, thereby improving the heat treatment effect of the transmission taper sleeve the goal of. Two transmission tapered sleeves are vertically sleeved on each vertical rod 3, and one end of the large outer diameter of the upper transmission tapered sleeve is set outside the small outer diameter end of the lower transmission tapered sleeve, that is, the top of ...

Abstract

The invention discloses a transmission taper sleeve carburization quenching heat treatment method and a tool thereof, and relates to the technical field of surface heat treatment of automobile parts.The method comprises the following steps that S1, a transmission cone sleeve fills a special tool; S2. the transmission taper sleeve is fed into a cleaning machine to be cleaned; S3, the cleaned transmission conical sleeve is fed into a preheating furnace to be heated; S4, after the transmission conical sleeve for completing preheating treatment is fed into a heating chamber of a gas carburizing box type multi-purpose furnace to complete carburization heat treatment, the mixture is transferred into an oil tank of the gas carburizing box type multi-purpose furnace for quenching heat treatment;S5, the transmission conical sleeve for completing carburization and quenching is conveyed into a cleaning machine to be cleaned; and S6, the cleaned and treated transmission taper sleeve is fed intoa tempering furnace to carry out tempering treatment. The transmission taper sleeve fills the special tool to complete the carburizing and quenching heat treatment operation, so that the purpose of improving the hardness and wear resistance of the outer circle surface of the transmission taper sleeve and reducing the inner hole hardness of the transmission taper sleeve is achieved.

Description

technical field [0001] The invention relates to the technical field of surface heat treatment of auto parts, in particular to a carburizing and quenching heat treatment method for a transmission taper sleeve and tooling thereof.
