Overview

-The 196 ℃ liquid nitrogen cryogenic box is suitable for the assembly of interference fit parts that contain components (such as planetary carriers, torsion arms, etc.) without heating or heating parts that may cause changes in part accuracy, material structure, and affect their mechanical properties. The contained components (such as pin shafts, elastic support shafts) can be frozen. Various hot work molds and cold work molds are used to assemble gears and shafts for various gearboxes and gearboxes. Assembly of precision mechanical parts. Assembly of various motor stators and rotors, automotive components, and engine parts. Please contact us for metal assembly boxes.

Product Details

Cold assembly equipmentThere are various specifications to choose from, including horizontal, vertical, square, cylindrical, etc. The equipment parameters are as follows:

Temperature control range: Room temperature to -190 ℃

Cooling rate: 0.1~10 ℃/min

Heating rate: 0.1~10 ℃/min

Temperature uniformity: ± 2 ℃, 0.5 hours after temperature equilibrium

Temperature control accuracy: ± 2 ℃

Control mode: artificial intelligence control, computer control, or touch screen control

During the product processing, liquid nitrogen is used for cooling, which significantly enhances the safety of the production process and the uniformity of the cryogenic process.

Cold assembly equipmentTemperature: The temperature for cold treatment is mainly determined by the martensitic transformation termination temperature Mf of the steel, and also takes into account factors such as the influence of cold treatment on mechanical properties and processability. For GCr15 steel, -70 ℃ is selected for cold treatment; When there are limitations on the precision requirements of the ring or equipment, the cold treatment temperature can be selected as -40 to -70 ℃; Ultra precision bearings can undergo cold treatment between -70 ℃ and -80 ℃. The supercooling temperature affects the impact fatigue and contact life of bearings.

Cold assembly equipmentAlthough the transformation of a large amount of martensite is completed during the tilting process when cooled to a certain temperature, a certain insulation time is required to ensure that the surface and core of a batch of rings reach the cold treatment temperature uniformly, usually 1-1.5 hours.
