Problems solved by technology

The shortcoming of this linear friction welding equipment is: the first, the servo valve that controls vibration oil cylinder assembly 2 to realize the high-frequency vibration of vibration slide table 4 is difficult to solve
Servo valves that require both high frequency response and large flow rate can only be imported, which is extremely expensive and difficult to maintain
Second, high energy consumption and low efficiency
The power of linear friction welding equipment is as high as hundreds of kilowatts, while the power consumed at the welding joint is only 1 / 20 to 1 / 30, and most of the power is used to overcome the inertial force generated by the vibrating parts, resulting in low efficiency and high welding costs

Description

technical field [0001] The invention belongs to welding technology and relates to the improvement of linear friction welding equipment. Background technique [0002] The principle of linear friction welding is: one test piece vibrates back and forth at high frequency, and the other is in contact with the vibrating test piece under a certain load force, friction heat is generated on the contact interface, the interface temperature rises rapidly, and the interface metal softens and undergoes plasticity. When the interface metal is extruded to a certain extent, the vibrating specimen stops vibrating quickly and maintains the load force for a certain period of time. The interface metal is welded together through mutual diffusion and recrystallization, thus completing the entire welding process. [0003] The block diagram of the current linear friction welding equipment can be found in figure 1 . It includes console 1, vibrating cylinder assembly 2, vibrating column 3, vibratin...
