four-column hydraulic pressHeat treatment can not only increase the service life of the four-column hydraulic press, but also improve the working efficiency of the four-column hydraulic press. Heat treatment does not change the shape of the workpiece and the chemical composition of the whole, but by changing the microscopic arrangement inside the workpiece, or changing the chemical composition of the cast iron channel and the appearance of the machine tool casting, to improve the performance of the workpiece. The primary feature is to improve the connotation quality of cast iron channel and machine tool bed castings. The tempering heat treatment of some castings on the four-column hydraulic press is an important process link. Castings must be treated by aging to improve their performance and the connotation quality of bed castings. Machine tool bed castings, bed column, machine tool table and other castings all heat treatment generally have annealing, normalizing, quenching and tempering four basic processes.
The tempering process shall be strictly observed during the tempering of the four-column hydraulic machine bed castings, and support bars shall be added to the dense or easily deformed parts of the ribs to avoid deformation and fracture caused by the tempering temperature. Special personnel should be assigned to guard the tempering furnace thermometer to control the temperature in time to avoid too high or too low temperature, which will have a great impact on the tempering workpiece. In order to make the mechanical properties, physical properties and chemical properties of the machine tool castings, in addition to the reasonable selection of materials and various forming processes, the heat treatment process is essential. All heat treatment is a metal heat treatment process that heats all cast iron plates, cast iron bending plates or machine tool bed castings, and then cools them at an appropriate rate to change all the mechanical properties of cast iron channels, plates, cast iron bending plates or machine tool bed castings.
In fact, to sum up, the four-column hydraulic press will be more stable and not easy to deform through heat treatment in the future. Since the four-column hydraulic press is inforging pressMachinery, no reciprocating movement is easy to form the deformation of the fuselage. Through the heat treatment in the future, can improve the blade of the fuselage. Extend the life of the machine tool. It can also create more value for you. So the same machine through the heat treatment quality will be upgraded.
