Embodiment Construction

[0016] 1. Compression forming: Add the configured gear hub metal powder into the cavity of the hydraulic press, pressurize and form it to make a gear hub blank, and demould to become a gear hub blank.

[0017] 2. Pre-sintering: Put the gear hub blank into the continuous mesh belt furnace, carry out continuous sintering at a temperature of 8500°C, and take it out from the continuous mesh belt furnace to become a pre-sintered gear hub.

[0018] 3. CNC machining: Fix the pre-sintered gear hub on the CNC machine tool, and process it according to the geometric size and shape of the gear hub to become a processed gear hub.

[0019] 4. Sintering: Put the processed gear hub into the sintering kiln for shaping and sintering to form a shaped and sintered gear hub.

[0020] 5. Shaping: Shaping the shaped sintered gear hub, removing burrs and sharp angles, so that it meets the technical requirements for the outer dimension and shape of the gear hub, and forms a shaped gear hub.

Abstract

The invention provides a processing technology for a powder metallurgy gear hub. A product gear hub is formed through the processes of metal powder press-forming, pre-sintering, numerical control machining, sintering, reshaping, high-frequency quenching, cleaning and packaging. The technical process of an automobile synchronizer gear hub processed by the processing technology is reasonable, the gear hub is convenient to process, the efficiency can be improved, the energy consumption is decreased, and the cost is reduced. The processing technology is suitable for being used for processing the automobile synchronizer gear hub.

Description

technical field [0001] The invention proposes a processing method for an inner gear hub of an automobile gearbox, specifically a powder metallurgy gear hub processing technology. technical background [0002] Synchronizer hubs are important components within automotive transmissions. Its overall precision and performance directly determine the safety and stability of the gearbox. It is a complex structural part with high density, high strength and high precision. [0003] At present, the domestic powder metallurgy synchronizer gear hub requires high precision, and after pressing and sintering with a powder metallurgy press, it cannot directly meet the drawings and technical requirements, and subsequent processing is required. The powder metallurgy synchronizer gear hub is made of high-strength powder, especially the D39 material used for high-end car gear hubs. After sintering, the surface hardness reaches HV5300 or more. Subsequent finishing and CNC machining are very dif...
