Abstract
The invention discloses a hydraulic station of an automatic friction welding machine, which comprises a motor pump unit, a main cylinder pressure-regulating valve unit, a main cylinder valve unit, a control valve unit, a lubricating portion and an oil tank. The motor pump unit, the main cylinder pressure-regulating valve unit, the main cylinder valve unit and the control valve unit are arranged on the top of the oil tank, and the lubricating portion is mounted on one side wall of the oil tank. The hydraulic station of the automatic friction welding machine is used for welding. During welding, high-pressure rubber hoses and electrical plugs are easy to be damaged by high-temperature splash such as welding slag, a protective cover added on the oil tank is capable of preventing damages caused by the splash such as the welding slag, and operation states of the hydraulic station can be observed clearly. In addition, by means of hydraulic transmission electrical control, the hydraulic station is high in power, low in noise, small in vibration and higher in stability and safety.
Description
Technical field
The present invention relates to a kind of automated friction welding machine Hydraulic Station.
Background technology
In the prior art, automated friction welding machine Hydraulic Station power is lower, and noise is big, and vibration is big, security and less stable.
Summary of the invention
The purpose of this invention is to provide a kind of automated friction welding machine Hydraulic Station.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of automated friction welding machine Hydraulic Station; Form by electric-motor pump group, master cylinder pressure regulator valve group, master cylinder valve group, control valve group, lubricated part, fuel tank; Said electric-motor pump group, master cylinder pressure regulator valve group, master cylinder valve group, control valve group are arranged on the fuel tank top, and said lubricated part is installed in the sidewall of fuel tank.
Said master cylinder pressure regulator valve component is three grades of Regulation Control.
Said master cylinder valve group comprises 3 electro-hydraulic reversing valves and 1 flow speed control valve.
Said control valve group control anchor clamps and mobile oil cylinder.
A kind of automated friction welding machine of the present invention Hydraulic Station is used to weld occasion, in welding process; High temperature such as the welding slag object that splashes is arranged, cause the damage of high-pressure rubber pipe and electric connector easily, so on fuel tank, add a protective cover; Can avoid the destruction of welding slag splash generation, also can see the working condition of Hydraulic Station clearly, adopt the hydraulic drive electrical control; Power is high, noise is low, vibration is little, improves happy stability and security.

Fig. 1 is the front view of a kind of automated friction welding machine of the present invention Hydraulic Station.
Fig. 2 is the vertical view of a kind of automated friction welding machine of the present invention Hydraulic Station.
Fig. 3 is the pressure-control circuit figure of a kind of automated friction welding machine of the present invention Hydraulic Station.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; Automated friction welding machine Hydraulic Station; Form by electric-motor pump group 1, master cylinder pressure regulator valve group 2, master cylinder valve group 3, control valve group 4, lubricated part 5, fuel tank 6; Electric-motor pump group 1, master cylinder pressure regulator valve group 2, master cylinder valve group 3, control valve group 4 are arranged on fuel tank 6 tops, and lubricated part 5 is installed in the sidewall of fuel tank 6, and Hydraulic Station is by double pump high-low pressure fuel feeding; The front pump pump is given master cylinder, is moved the clamping cylinder fuel feeding. and the back pump is given the rotating clamp locking oil cylinder, is moved clamping cylinder, brake and control electro-hydraulic reversing valve guide part fuel feeding, the space that can practice thrift Hydraulic Station.
Three grades of Regulation Control of master cylinder pressure regulator valve component can be controlled different phase pressure, can adjust 3 pressure and system unloaded function, in three grades of pressure-control circuits (three grades refer to P1.P2.P3 and P3>P2>P1); When reversal valve 161 outages, the adjusting pressure P 1 of system pressure decision overflow valve 151 is when reversal valve 161 gets electric and reversal valve 162 cuts off the power supply; The adjusting pressure P 2 of system pressure decision overflow valve 152, reversal valve 161 and reversal valve 162 all get when electric, and system pressure determines the adjusting pressure P 3 of overflow valve 17; Reversal valve 163 gets electric, and system unloaded is at former three grades of pressure-control circuits; Pressure between reversal valve 161 and the overflow valve 151 is zero, and when reversal valve 161 outages, the pressure that overflow valve 17 gets Long-distance Control mouth x place drops to zero back by being raised to P1 by P3; System entails can impacted like this, if the reversal valve 161 in loop is exchanged with overflow valve 151, the Long-distance Control mouth of overflow valve 17 is linked to each other earlier with overflow valve 151P chamber; Overflow valve 151T chamber links to each other with reversal valve 161, like this reversal valve 161 electric after, pressure can drop to P1 from P3; So just bigger impact be can not produce, when two-position four way change valve is made the bi-bit bi-pass reversal valve, reversal valve P chamber and A chamber used generally speaking; Because two-position four way change valve, guiding valve is let out in moving and having when switching-over, leaks oily untimely row; When switching-over, bigger impact is arranged also, the life-span of valve also can be affected like this, for fear of the impact meeting oil sump tank is drawn in the T chamber of reversal valve.
In the master cylinder valve group 3; With 3 electro-hydraulic reversing valves and 1 flow speed control valve synergy; Electro-hydraulic reversing valve selects for use external control to leak; Control oil back pump is supplied with. the switching-over of electro-hydraulic reversing valve control master cylinder, and the switching of electro-hydraulic reversing valve control master cylinder rod chamber, differential, electro-hydraulic reversing valve and flow speed control valve can be realized two speed of master cylinder work.
The 4 control anchor clamps rotations of anchor clamps and control valve group, move oil cylinder clamping with unclamp, the rotation of brake and braking and the guide who offers master cylinder valve group electro-hydraulic reversing valve control oil, accumulator plays pressurize, elimination pressure oscillation effect.
