Gear forging die and forging process thereof

Abstract

The invention discloses a gear forging die, and relates to a die. The gear forging die particularly comprises a base, a workbench, a lower die and an upper die; the workbench is installed on the basethrough support legs, the lower die for gear forging is installed on the workbench, and four corners of the top surface of the workbench are correspondingly and fixedly connected with the bottom surface of a top plate through support rods; a punch hammer used for forging work is installed in the middle of the bottom face of the top plate through a hydraulic cylinder, vertical connecting rods are slidably installed at the four corners of the top plate correspondingly, the top ends of the connecting rods are fixedly connected with the four corners of the bottom face of a lifting plate correspondingly, and the bottom ends of the connecting rods are fixedly connected with the four corners of the top face of a mounting plate correspondingly; the mounting plate is located below the punch hammer;and the upper die for gear forging is installed on the bottom surface of the mounting plate. According to the gear forging die and the forging process thereof, in the implementation process, the gearcan be formed at a time through the matching effect of the upper die, the lower die and a sliding block, and the gear forging forming process is effectively reduced.

Description

technical field

[0001] The invention relates to a die, in particular to a forging gear die and a forging process thereof. Background technique

[0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. Gears are widely used in mechanical transmission. With the rapid development of modern industry, how to reasonably design gear processing technology and effectively improve the precision and production efficiency of gears has become an important content in the industry.

[0003] In the existing technology, when producing gears, multiple processes are usually required to complete the rough blank...
