The cold assembly of industrial freezer is generally used for the case that the material of the containing part and the contained part is different, the mechanical property is different, the hardness of the material is quite… Read more The application of cold assembly technology of industrial freezer in machine assembly

The thermal insulation material of ultra-low temperature freezer

The ultra-low temperature freezer adopts polyurethane as thermal insulation material. It is important to choose correct insulation material to thermal insulation for the ultra-low temperature freezer. At this point, the importance of insulation materials will be revealed. Suitable insulation materials can minimize the impact of the atmosphere on the temperature in the freezer and minimize… Read more The thermal insulation material of ultra-low temperature freezer

Control method of retained austenite in industrial freezer cold treatment

There are always some retained austenite after quenching. Too much retained austenite is harmful to the service life and hardness of parts, which will cause the instability of soft spot and size. However, a proper amount of retained austenite can improve the fatigue strength of parts. We can control the quality and service life of… Read more Control method of retained austenite in industrial freezer cold treatment

Using industrial freezer to reduce and eliminate the generation of retained austenite after quenching

Martensitic transformation is a kind of cutting deformation core, not depending on diffusion. It’s an incomplete transformation. 1.Austenite must have enough cooling rate at high temperature, so that austenite will not undergo equilibrium decomposition at high temperature. 2.When austenite is cooled to MS point, martensitic transformation will take place, and it is formed by cooling.… Read more Using industrial freezer to reduce and eliminate the generation of retained austenite after quenching

Prevention of Bearing Deformation in Freezing Assembly of Industrial Freezer

At present, the rolling bearing is refrigerated for 30 min (- 196 ℃) in the industrial freezer before assembly on the motorcycle, and then loaded into the motorcycle. This technology has been widely used in motorcycle industry. Before, motorcycles used imported bearings. In order to realize the localization of imported bearings, our factory produced alternative… Read more Prevention of Bearing Deformation in Freezing Assembly of Industrial Freezer

Cold assembly refrigerator The equipment can be used in the assembly of various precision mechanical parts and has many advantages in the application of… Read more The application range of industrial cryogenic freezer

Use Industrial Freezer to Freeze Hardening in Precision Gear Manufacturing

The external dimension and microstructure of precision gear can be stabilized by low temperature treatment of industrial freezer. In order to control the noise of gear loading and transmission, the mesh cloth size is required to be stable, because the change of gear size affects the center distance of gear unit. It has been found… Read more Use Industrial Freezer to Freeze Hardening in Precision Gear Manufacturing

Knowledge of Interference Assembly and Application of Industrial Freezer

DefinitionClearance fit, interference fit and transition fit can be formed according to different relative position relations of combined hole and shaft tolerance zone. Among them. A fit with an interference (including a minimum interference equal to zero) is called an interference fit. In this case, the tolerance zone of the hole is under the tolerance… Read more Knowledge of Interference Assembly and Application of Industrial Freezer
