Background
In the manufacturing process of precision products, the problem of interference assembly of materials with different specific heat exists frequently, and the assembly usually requires the tight combination of two materials to achieve the purpose of sealing or high strength (integrity). To meet these requirements, the size of the fitting bore must be smaller than the diameter of the fitting bore. A certain degree of co-mingling of the two materials is established, only then is the sealing achieved after assembly.
There are generally cold-charging and hot-charging methods. The hot-charging method is to heat a workpiece with holes to enlarge the hole diameter, then to charge the shaft member at normal temperature, and after natural cooling, the holes shrink to form firm coating. The cold-assembling method needs to make the shaft member be soaked in refrigerant to reduce the external diameter of the shaft, then the machine is selected for assembling, and no matter the cold-assembling method or the hot-assembling method uses the principle that the material expands with heat and contracts with cold, the two assembling methods have respective advantages and disadvantages, the hot-assembling method usually uses oil as a heating medium, grease and oxide particles thereof are brought into a blending area after assembling, and the grease and the oxide particles thereof are seeped and evaporated in the future use of the workpiece to form oil pollution, so that the oil pollution is not sensitive to equipment and places, but the oil pollution is not suitable for the equipment and places if the workpiece is used for high-environment sensitive equipment such as life science, molecular biology, semiconductors, photoetching machines and the like. A cold assembly must be used.
The cold assembly uses liquid nitrogen as a cooling medium, and has the advantages that the assembled product is highly clean, and an intersection area is free from pollution, but the cold assembly has the following problems:
1. liquid nitrogen is easy to boil and evaporate at normal temperature, and if the assembly process is not controlled, the consumption is extremely high, and the cost is increased;
2. liquid nitrogen is an ultralow temperature substance, a common container is easy to crack and deform, and a simple metal container is not easy to preserve heat;
3. the assembly process is required to be rapid, otherwise the frozen workpiece is exposed to air and is easy to warm up, and assembly failure is caused.
