Description

Technical Field

[0001] The utility model relates to the technical field of forging, in particular to a forging device for a transmission gear of an automobile gearbox. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets to cause them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as cast porosity produced during the metal smelting process and optimize the microstructure. At the same time, since the complete metal flow lines are preserved, the mechanical properties of forgings are generally better than those of castings of the same material. When producing and processing transmission gears, it is usually necessary to forge the steel through a forging device. After forging, the steel is turned and milled to produce and process the transmission gears.

[0003] During the use of existing forging devices, the steel is usually turned over manually so that the forging device can forge and strike the steel in all directions. However, in actual use, the steel is prone to displacement when struck, which will cause vibration to the clamping arm, and then cause pulling on the operator's arm. Long-term operation can easily cause discomfort to the operator's arm and reduce production and processing efficiency. For this reason, we propose a forging device for automobile gearbox transmission teeth. For this reason, we propose a forging device for automobile gearbox transmission teeth. Utility Model Content
