Buffer gear precision cold forging process and die
Buffer gear is a kind of gear widely used in various fields. In order to ensure its high precision, special attention should be paid to the cold forging process and mould design. This article mainly analyzes the process of precision cold forging and the design criteria of the die.
The cold forging process of precision buffer gears can be divided into two steps: sample processing and parts processing. For sample processing, usually some kind of material such as steel or aluminum alloy is used as the material. The sample processing involves forging the parts shape, heat treatment and then collection into the die. In parts processing, the sample is placed in the die and undergoes forge forming, quenching and tempering, trimming and polishing. After this cold forging process, the precision of the buffer gears is greatly improved, and more intricate and complex shapes can be made.
The design criteria for the die used in the precision cold forging process mainly include the following aspects:
(1) Die material: it should be able to withstand the high temperature generated in the cold forging process, and have higher strength and wear resistance.
(2) Die geometry: different forms of die geometry can be used to form different shapes of buffer gears.
(3) Die loading: the die should be able to withstand the high load generated in the forging process without deformation.
(4) Clearance: the die should have proper clearance to ensure the formation of the buffer gears.
To sum up, precision cold forging is a special processing method for buffer gears, which requires the design of special dies, and the process requires the use of high quality die material, proper die geometry and clearance. The process greatly improves the precision of the buffer gears and can be used for more intricate and complex shapes.
