Description

Technical Field

[0001] The utility model relates to the technical field of railway vehicle accessories, in particular to a core plate wear plate material reaction system. Background Art

[0002] The cast core wear plate is one of the key parts of railway vehicles. It is installed in the middle of the bolster of the freight car bogie and supports the entire car body together with the side bearing. The friction resistance of the cast core wear plate constrains the lateral movement of the car body to a certain extent, so the performance requirements of the cast core wear plate directly affect the safety of the car body operation. When producing the core wear plate, a certain amount of raw materials need to be melted and added to the vacuum dehydration tank. After adding the catalyst, the vacuum pump is quickly turned on, and the vacuum degree is maintained at ≥-0.095MPa. When the temperature reaches 138-142℃, vacuum dehydration is carried out for 10-20 minutes. After dehydration, the catalyst is added to obtain the active melt material, and then the active melt material is poured into the mold for casting and molding. When our company is currently producing, after manually taking the materials, we first heat them in a water boiler to melt them, then pour the molten raw materials in the boiler into a vacuum dehydration kettle, add a catalyst into the vacuum dehydration kettle, turn on the vacuum pump and keep the vacuum degree within a certain range, a thermometer is provided at the spout of the vacuum dehydration kettle, and when the temperature rises to a certain temperature, vacuum dehydration is performed for a certain period of time, and finally a co-catalyst is added to form an active solution material.

In view of the above problems, the utility model provides a core disc wear disc material reaction system with a high degree of automation, good product quality performance, high product consistency, and a safe production process.
