Application of Industrial Freezer in Cold Assembly of Copper Sleeve Bearing

Application of Industrial Freezer in Cold Assembly of Copper Sleeve Bearing

First, application scope of industrial freezer:

1. Assembly of various hot work molds and cold work molds

2. Gear and shaft assembly of various industrial gearboxes and gearboxes

3. Mechanical parts assembly

4. Various types of motor stator and rotor assembly

5. Auto parts, engine parts

Industrial freezer applications are found in aerospace, hardware, tools, molds, friction couples, processing, measuring tools, textiles, automobiles and many other fields

Second, the practical application of industrial freezer:

1. Industrial refrigerators can significantly change the structure, effectively promote the transformation of retained austenite to martensite and the precipitation of ultra-fine carbides, so that the product can obtain better comprehensive mechanical properties. After cryogenic treatment, the service life of the product is more conventional The heat treatment has been improved and has a very important use value.

2. The industrial freezer is suitable for containing parts (such as planet carriers, torsion arms, etc.) without heating or heating parts that will cause changes in parts accuracy, material structure, and affect their mechanical properties. ) assembly of interference fit parts that can be frozen.

Third, the use of industrial refrigerators attention points:

1. After the industrial freezer is installed or reused for a long time, the cooling rate should be reasonable. When not in use for a long time, the main power supply should be cut off and ensure that it is not polluted by moisture, ash and other substances.

2. Do not stack the sundries on the industrial freezer, so as to avoid the deformation of the storage plate affecting the thermal insulation performance, and keep the surrounding passages unobstructed. Only by ensuring good heat dissipation can a good cooling effect be guaranteed. The storage place should be kept dry, clean and free from inflammable and explosive materials to ensure that there are no potential safety hazards.

3. The collision and scratching of the industrial freezer by hard objects should be avoided, as it may cause depression and corrosion of the pavilion board, which will seriously reduce the local insulation performance.

4. Sealing maintenance, since the equipment is made of several insulation boards, there are certain gaps between the boards. These gaps will be sealed with sealant during construction to prevent air and water from entering. Therefore, some seal failures in use should be repaired in time.

5. Check whether there is condensation outside the industrial freezer, check whether the door is flexibly opened and whether it is sealed.
