Description

Scraper conveyor is the running track of the shearer, so the durability requirements are high, directly affect the production capacity and economic benefits, its die forging accessories specifications are diverse, today double zhi Small make up take you to explore under the scraper accessories pin rail forging process.

Pin rail is located in a central slot, is in the service of the coal winning machine walking, coal winning machine rack meshing drive wheel with pin rail coal winning machine in walking on the pin rail, so the pin rail in addition to the need to have proper perforation, also need to have higher strength and stability, belong to the deep hole pin rail complex thin-wall forgings, heavy blow machine pin rail important generally in more than *0 kg, material is *2 crmo alloy steel, etc.

Pin rail is located in a central slot, is a deep hole complex thin-wall forgings, the change of cross section, and the local depth is larger, multiple perforation in forging even thin skin, rapid temperature drop, the metal flow not easily, the chamber full of die hard, so we need bigger blow energy, need to take appropriate means of blocking, make reasonable distribution ahead of metal materials. Process flow: 1. Blanking → heating → billet making → die forging → punching → trimming → correction → heat treatment → cleaning → inspection → qualified forgings.

Scraper parts pin rail forging process adaptability, high production efficiency, forging surface quality is good, suitable for mass production. Henan Shuanzhi mainly forging, quality material standardization, if there is a demand, pay attention to the official website of Henan Shuanzhi.
