The gear rail is located above the central trough of the scraper conveyor, and the planet wheel of the shearer drives the shearer to walk on the pin rail through meshing with the gear rail tooth surface. Therefore, the design requirements of the gear rail of Zhangjiakou forgings are relatively high. Today, we will talk about the gear rail forging process.
The cross section of the cog and rail varies greatly, the local depth is large, the perforation is even thin, the temperature drops fast, the metal is not easy to flow, the forging cavity is difficult, it needs a greater impact force. The key to forging forming lies in how to ensure the rational distribution of the blank and make the blank evenly distributed in advance. Now the forging process scheme of secondary forming is adopted. Roll forging is carried out first, then preforging and final forging are carried out. The technological process of die forging is as follows: blanking - heating - roll forging - preforging - final forging - trimming - punching - modulation - sanding - inspection - qualified forgings.
In addition to the need to have a suitable tooth hole, the rail also needs higher strength and stability. Knowing the forging process of Zhangjiakou forgings, we can find the manufacturer we trust. Henan Shuanzhi sincere service customers, quality to create a reputation.
