Motor 214, the first overflow valve 215 and the second overflow valve 216, the first overflow valve 215 are connected with pressure gauge 217, the second overflow valve
216 are connected with accumulator 218.
Pressure gauge 217 is for showing pressure value.The effect of accumulator 218 is to reduce hydraulic fluctuation peak value, such as in electricity
When magnet valve 213 commutates, there is a moment, pressure pipeline is shut, and at this moment the pressure of hydraulic oil can leap high suddenly, accumulator
218 can substantially reduce pressure pulse
The application is provided with the first overflow valve 215 and the second overflow valve 216 in hydraulic system 210, wherein the first overflow
Same valve can be used in valve 215 and the second overflow valve 216, is adjustable and the valve of control pressure, the setting of the first overflow valve 215
Pressure is impermissible for transferring again 300Bar (or being optionally tuned into other numerical value), is used as the peace of hydraulic system 210
Full valve makes the pressure of hydraulic system 210 not exceed 300Bar under any circumstance.Second overflow valve 216 is then used as adjusting
Pressure valve, user can at will transfer, if it is desired to which pressure is big (such as welding slab), pressure can be turned up, if it is desired to pressure
Small (such as welding thin plate), pressure can be turned up.
Agitating friction may make to weld by adjusting the second overflow valve 216 by the setting of above-mentioned hydraulic system 210 as a result,
Pressure adjustable must be descended when connecing, and guarantees that lower pressure remains definite value in Friction Stir Welding, and will not be because of volume under pressure
Size variation and generate excessive lower pressure, for high quality Friction Stir Welding processing advantage is provided.
About pressure regulation, it should be noted that the pressure of hydraulic system 210 is determined by load, and bigger (processing knife is loaded
The torque of tool, such as the torque of friction stir welding), 210 pressure of hydraulic system can be got higher automatically, until being more than pressure regulator valve
The pressure that (the second overflow valve 216) is set up, load become larger again, and hydraulic motor 214 will stop operating, and pressure oil is all through toning
Pressure valve enters low pressure pipeline, returns to fuel tank 211 by return filter 219, at this moment just needs pressure regulator valve that pressure is turned up.General feelings
Under condition, it is not in stalling phenomenon that pressure regulator valve, which is turned up a little, the general plate for welding 6mm thickness, and 210 pressure of hydraulic system is practical
Value only 40 arrives 70bar (related with friction stir welding shape and revolving speed, transverse shifting speed).
The effect of solenoid valve 213 is to realize friction stir welding stalling and positive and negative rotation, and the application uses the electricity of H-shaped function
Magnet valve, when not having electromagnet action, the spool of solenoid valve is located at middle position, and the oil of all pipelines is all and low-pressure oil return pipe
(oil pipe of oil return box) communicates, so 210 pressure of hydraulic system is low pressure, at this point, 212 output pressure of hydraulic pump is low pressure, electricity
Electromechanics stream very little, after solenoid valves, spool movement, pressure oil passes through hydraulic motor 214, and hydraulic motor 214 is pushed to rotate,
Then become low pressure oil and flow to fuel tank 211 from oil return pipe.
The torque of hydraulic motor 214 determines the size of pressure, and torque is turned round from the friction-stir of friction stir welding
Square, so, the pressure of hydraulic system 210 is actually determined by the torque of friction stir welding.
In certain embodiments, referring to FIG. 5, hydraulic system 210 can also include oil absorption filter 2101, for guaranteeing
Big impurity is free of into the hydraulic oil in hydraulic pump 212, it is ensured that hydraulic pump 212 will not premature abrasion.
In certain embodiments, referring to FIG. 5, hydraulic system 210 can also include shut-off valve 2102 (also known as switch valve or
Person's ball valve), which is switched on when flat, have to check for whether shut-off valve 2102 is opened before booting every time, if
It being not turned on, hydraulic oil not can enter hydraulic pump 212, once booting, hydraulic pump 212 necessarily damage.Only in the dimension that needs repairing
When protecting hydraulic system 210, just turns off shut-off valve 2102, spill the hydraulic oil in fuel tank 211 not.
In addition to the above, with continued reference to FIG. 5, hydraulic system 210 is additionally provided with impact resistance valve 2103, for protecting liquid
A kind of trimmer valve of pressure motor 214 and solenoid valve 213, pipe-line system.

Throttle orifice, the micro orifice are connected respectively to the both ends of hydraulic motor 214.
It is possible thereby to be appreciated that, when the rotation of hydraulic motor 214 is stirred friction welding, the one of hydraulic motor 214
End is the high pressure oil entered, and the other end is the low pressure oil of outflow, if stopped operating, is powered off to solenoid valve 213, solenoid valve 213
Middle position can be changed to, at this moment the oil of hydraulic pump 212 come can flow into oil returning tube by the H-shaped channel of position in solenoid valve 213
Oil return box 211,214 both ends of hydraulic motor also all become low pressure oil, stop operating, but have a problem, in the spool of solenoid valve 213
During moving to middle position from one end, there is a moment, solenoid valve 213 is shut all by its pipeline locking, accumulation of energy
Device 218 protects hydraulic pump 212 etc. at this time, but 214 both ends of hydraulic motor also can be problematic, if high-speed rotating hydraulic motor
The pipeline at 214 both ends is shut suddenly, due to the effect of inertia of hydraulic motor 214 rotatable parts and stirring system rotatable parts, meeting
The pressure of 214 flowline of hydraulic motor is caused to explode, and 214 oil inlet pipe pressure of hydraulic motor is suddenly become by original high pressure oil
Negative pressure, this will cause great impact.Impact resistance valve 2103 normally stirring operation when, internal piston be under pressure oil work
With, positioned at one side of low pressure, when solenoid valve 213 acts, pressure oil suddenly becomes negative pressure, and low pressure high pressure occurs on one side suddenly,
At this moment, piston can move on one side to negative pressure, since there is orifice restriction effect at both ends, make piston motion by certain resistance, make to live
Plug is unlikely to move too fast too quickly and damage, while the effect of micro orifice can also make impulse high voltage be converted into thermal energy to dissipate.
