Abstract

The invention discloses a precision forging plastic forming process of a power take-off device flange shaft. Forward squeezing, upsetting squeezing, reversing squeezing, diameter-reducing squeezing and cold finish are carried out on a bar material, so that blank which basically meets the size requirement of the power take-off device flange shaft is forged, and then the blank is machined through a machine tool to form a finished product of the power take-off device flange shaft. The machining method is simple, the precision requirement of the power take-off device flange shaft is met, manufacturing cost and the production cycle are reduced, and meanwhile, the precision forging plastic forming process conforms to the current development trend of the manufacture industry in the world.

Description

technical field [0001] The invention relates to a flange shaft of a power take-off, in particular to a warm forging process for a flange shaft of a power take-off. Background technique [0002] The English abbreviation of the power take-off is PTO, which is a set of variable speed gears, also known as the power output device. It is generally composed of a gearbox and a clutch. It is a separate gear, put it in this gear, and the lift pump can run as soon as you add gas. The lift pump is a hydraulic device that lifts the car to realize the self-unloading function. Dump trucks, fire trucks, cement mixer trucks, refrigeration and other special vehicles that require extra power are obtained through a power take-off, which is an additional device installed on the outside of the gearbox, which obtains power from a certain gear of the gearbox . The power on or off is controlled by a solenoid valve in the cab. The power take-off drives the high-pressure oil pump for the dump truc...
