Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a forging and stamping device for an automobile drive shaft. Background Technique

[0002] The automobile drive shaft is an important component for transmitting power in the automobile transmission system, and its structure and function are crucial for the operation of the automobile. The automobile drive shaft is the shaft that can transmit power in the drive shaft of the universal transmission device, mainly used to transmit the power of the engine to the wheels to make the automobile generate driving force. It is a key component connecting the gearbox and the drive axle, and works together with the two to achieve power transmission. The automobile drive shaft mainly consists of the following parts: Shaft tube: The shaft tube is the main body of the drive shaft, made of high-strength steel or aluminum alloy to withstand the torque and bending moment generated during transmission. The inside of the shaft tube is usually a hollow structure to reduce weight and facilitate the arrangement of other components. Expansion sleeve (splined shaft): The expansion sleeve is located at both ends of the drive shaft and is used to compensate for the length change caused by vibration and temperature change during the driving process of the automobile. It is slidably connected to the shaft tube through splines and allows length adjustment within a certain range. Universal joint: The universal joint is an important component connecting the drive shaft and the transmission or the drive axle, allowing angular change between the two and transmitting torque at the same time. Common types of universal joints include ball cage type, three-pronged type, etc., which have different structural characteristics and application ranges. Bearings and seals: The bearings are used to support the rotational movement of the drive shaft and reduce the frictional resistance; the seals are used to prevent lubricating oil leakage and dust from entering the inside of the drive shaft.

[0003] The working principle of the automobile drive shaft is to transmit the power of the engine to the wheels through the mutual cooperation of three important components: the shaft tube, the expansion sleeve and the universal joint. During the transmission process, the drive shaft needs to maintain dynamic balance to ensure stable power transmission. Generally, the drive shaft has to undergo a dynamic balance test before leaving the factory and is adjusted on a balancing machine. Special automobile drive shafts are mainly used in models such as oil tank trucks, refueling trucks, sprinkler trucks, sewage suction trucks, manure suction trucks, fire trucks, high-pressure cleaning trucks, road wreckers, aerial work platforms, garbage trucks, etc. These models have relatively high requirements for the load-bearing capacity and stability of the drive shaft, so high-quality drive shafts are required to ensure the normal operation of the automobile. In short, the automobile drive shaft is an important component in the automobile transmission system, with a complex structure and important functions. To ensure the normal operation of the automobile, it is necessary to select high-quality drive shafts and perform regular maintenance and upkeep.

[0004] In the production process of automobile drive shafts, forging and stamping are key technological steps. In the operation process of existing drive shaft forging and stamping devices, there are often problems such as uneven force, easy damage to drive shaft blanks, and poor applicability. These problems not only affect the manufacturing efficiency of drive shafts, but also reduce the quality and performance of drive shafts. For this reason, we provide a forging and stamping device for automobile drive shafts. Summary of the Utility Model
