Features of china precision four-guide column punch
The china precision four-guide column punch relief valve single-stage pressure regulating circuit is composed of quantitative pump, relief valve and hydraulic cylinder, which is the most basic pressure regulating circuit. Has the following features:
The opening pressure of the relief valve can be adjusted by the pressure regulating spring. If the pre-tightening amount of the pressure regulating spring of the relief valve is set, the maximum value of the oil supply pressure can be set, and the actual working pressure of the hydraulic press system is determined by the load.
When the external load pressure is less than the set pressure of the relief valve, there is no overflow flow at the relief valve. At this moment, the relief valve acts as a safety valve. When the relief valve is a single-stage manual relief valve , in a working cycle of the system pressure regulating circuit, the pressure of the relief valve is no longer adjusted.
1. The china precision four-guide column punch reduces mass and saves material.
2. Reduce the number of parts and molds to reduce mold costs. Hydroforming parts usually only need one set of dies, while stamping parts mostly require multiple sets of dies. The number of hydroformed engine bracket parts has been reduced from 6 to 1, and the number of radiator bracket parts has been reduced from 17 to 10.
3. It can reduce the amount of welding for subsequent machining and assembly.
4. Improve strength and stiffness, especially fatigue strength, such as hydroformed radiator brackets, whose stiffness can be increased vertically and horizontally
5. The china precision four-guide column punch reduces production cost. According to the statistical analysis of the applied hydroformed parts, the production cost of hydroformed parts is lower than that of stamping parts, and the cost of die is reduced.
