Problems solved by technology

[0004] However, in this gear processing technology, after the workpiece is hobbed, there are a large amount of debris on the outer peripheral gear surface of the workpiece. If the debris is not treated but directly carburized and hang-polished, there will be unevenness on the surface of the workpiece. The possibility of affecting the quality of gear processing

Embodiment 1

[0039] Embodiment 1: It is a kind of external gear sleeve processing technology disclosed by the present invention, including the following processing steps:

[0040] Blank material cutting: choose 42CrMo as the blank material, and cut the ingredients into segments according to the specifications and sizes of the external gear bushing through a sawing machine to obtain the first processed product;

[0041] Preheating: Put the first processed product into a heating furnace and heat it at 300°C for 1 hour until the first processed product is heated to 1150°C, and then take it out of the heating furnace to obtain the second processed product;

[0042] Forging forming: the second processed product is hot-forged at a temperature of 850°C by a forging press, and then cooled, so that the second processed product is processed with a shaft sleeve through hole along the axial direction to obtain the third processed product;

[0043] Milling treatment: use milling-cleaning integrated equ...

Embodiment 2

[0048] Embodiment 2: Different from Embodiment 1, it is a kind of external gear sleeve processing technology disclosed by the present invention, which includes the following processing steps:

[0049] Blank material cutting: choose 42CrMo as the blank material, and cut the ingredients into segments according to the specifications and sizes of the external gear bushing through a sawing machine to obtain the first processed product;

[0050] Preheating: Put the first processed product into the heating furnace and heat it at 300°C for 1.25 hours until the first processed product is heated to 1150°C, and then take it out of the heating furnace to obtain the second processed product;

[0051] Forging forming: the second processed product is hot-forged at a temperature of 1000°C by a forging press, and then cooled, so that the second processed product is processed with a shaft sleeve through hole along the axial direction to obtain the third processed product;

[0052] Milling treat...

Embodiment 3

[0057] Embodiment 3: The difference from Embodiment 1 is that it is a kind of external gear sleeve processing technology disclosed by the present invention, which includes the following processing steps:

[0058] Blank material cutting: choose 42CrMo as the blank material, and cut the ingredients into segments according to the specifications and sizes of the external gear bushing through a sawing machine to obtain the first processed product;

[0059] Preheating: Put the first processed product into the heating furnace and heat it at 300°C for 1.5 hours until the first processed product is heated to 1150°C, and then take it out of the heating furnace to obtain the second processed product;

[0060] Forging forming: the second processed product is hot-forged at a temperature of 1150°C by a forging press, and then cooled, so that the second processed product is processed with a shaft sleeve through hole along the axial direction to obtain the third processed product;

Abstract

The invention discloses an external gear shaft sleeve machining technology and milling-clearing-integration equipment thereof. The technology mainly comprises seven machining procedures of blank cutting, preheating, forge piece forming, milling treatment, carburizing treatment, furnace discharging and cooling, and detection warehouse-out, wherein in the milling treatment machining procedure, scrapiron bonded to the outer side of an external gear shaft sleeve is cleared away through the milling-clearing-integration equipment, so that the possibility that the surface of the external gear shaftsleeve is uneven due to the fact that the scrap iron is bonded to the outer side of the external gear shaft sleeve is reduced, and the effect of improving the machining quality of external gear shaftsleeve products is achieved.

Description
