When the upper mold base is working, the overall force is even, and its strength, precision and surface hardness fully meet the needs of the work; because the quality of the annular cushion is small (15kg), it is very convenient for daily inspection, maintenance and replacement; the repair time of the scheme is short. The cost is low. Matters needing attention The above solution solves the problem of strength and hardness of the bearing surface G. However, since the annular pad still needs to be fixed with 4-M20 screws, and the screw holes are on the mold base, the mechanical properties cannot be improved. Improper, it is still possible to overload it and cause deformation. Therefore, strict requirements must be imposed on the operation. Each time the mold is replaced, the tightening state of the screws should be specifically checked, and the screws and washers that meet the requirements should be selected. In order to ensure the quality of the product and the order period, after analysis and research, pay attention to the quenching and tempering process to make the parts have good comprehensive mechanical properties. However, there are many factors affecting quenching and tempering, usually including raw materials, heating, cooling and high temperature tempering. The chemical composition and internal structure of the raw materials directly affect the comprehensive mechanical properties of the parts. The large-sized alloy steel forgings such as eccentric bodies are supplied with forged blanks by the external factory. To ensure the quality, the raw materials are inspected after the raw materials are put into the factory. Ultrasonic flaw detection is required, and the quenching and tempering process can be carried out after passing the test. Heating (before quenching) According to the current state of the plant equipment, eccentric body conditioning can only be heated in a gas reverberatory furnace. However, this type of furnace is difficult to control temperature, and it is usually only possible to manually adjust the temperature of the furnace nozzle to control the temperature. The requirements for the operator are strict, and it is necessary to have a sense of responsibility, but also to observe and adjust the temperature to ensure the process heating temperature. Due to the large cross section of the eccentric body and the complicated shape, the temperature difference between the inside and the outside is likely to be large when heating, and the thermal stress and the tissue stress are also large.
