Description

A kind of bender is used hydraulic valve bank

Technical field

The utility model relates to the bender Hydraulic Field, and particularly a kind of bender is used hydraulic valve bank.

Background technique

Bender divides two kinds by the control oil cylinder method of synchronization, and a kind of is common (turning round axle synchronously) bender, turns round connecting rod through machinery and carries out synchronously; Another kind is the synchronous numerical control bender of electron hydraulic proportional servo control oil cylinder, and is because machinery is turned round the synchronous bender control of connecting rod simply, easy to operate; Cheap, and less demanding to the operator, therefore use very universal at home; The hydraulic control system of employed common bender is main with homemade common plate valve mainly at present, and therefore not only volume is bigger, and the control debugging is complicated; And oil leakage phenomenon also can happen occasionally, thereby influences bender greatly.

The model utility content

To above problem, the purpose of the utility model provides a kind of bender and uses hydraulic valve bank, adopts threaded cartridge valve; Make the valve of not being with valve body be arranged in the hole of valve piece,, make between these valves and communicate with each other through the inner passage in the valve piece; Thereby reach various control effects, for reaching this purpose, the utility model provides a kind of bender to use hydraulic valve bank; Comprise main valve body, side valve body, solenoid directional control valve, safety valve, back pressure valve, ball valve, throttle orifice, one-way valve, outer throttle orifice, two logical screw-in cartridge valve, one-way throttle valves and far transfer valve; Said side valve body is arranged on the main valve body side, and said first solenoid directional control valve and second solenoid directional control valve are arranged on the side valve body side surface, and said safety valve is installed in the main valve body inboard; Said first ball valve is arranged on above the main valve body; Said second ball valve is arranged on the main valve body side, and said back pressure valve is arranged on the main valve body opposite side, and said two logical screw-in cartridge valves are arranged in the main valve body; Said accent valve far away is arranged on the two logical screw-in cartridge valves; Said second throttle orifice is arranged between accent valve far away and the two logical screw-in cartridge valves, and said one-way valve, outer throttle orifice and one-way throttle valve are arranged on the main valve body outside, and said first segment discharge orifice is provided with accent valve far away side.

As the further improvement of the utility model, said first ball valve and second ball valve are Solenoid ball valve, and this patent ball valve can adopt Solenoid ball valve, also can adopt other forms of ball valve, and producer can select as required.

The purpose of the utility model provides a kind of bender and uses hydraulic valve bank, adopts threaded cartridge valve, makes the valve of not being with valve body be arranged in the hole of valve piece; Through the inner passage in the valve piece, with communicating with each other between these valves, thereby reach the control effect; Design will significantly reduce the volume of valve body and the debugging difficulty of whole valve body like this; And, therefore communicate with each other, so be difficult for taking place oil leakage phenomenon through the inner passage because this patent is a threaded cartridge valve.

Embodiment

Below in conjunction with accompanying drawing and embodiment model utility is done detailed explanation:

The purpose of the utility model provides a kind of bender and uses hydraulic valve bank, adopts threaded cartridge valve, makes the valve of not being with valve body be arranged in the hole of valve piece, through the inner passage in the valve piece, makes between these valves and communicates with each other, thereby reach various control effects.

As a kind of specific embodiment of the utility model, the utility model provides plan view as shown in Figure 1, and plan view is as shown in Figure 2; Rear view is as shown in Figure 3, and left view is as shown in Figure 4, and right elevation a kind of bender as shown in Figure 5 is used hydraulic valve bank; Comprise main valve body 1-1, side valve body 1-2, solenoid directional control valve, safety valve 3, back pressure valve 4, ball valve, throttle orifice, one-way valve 7, outer throttle orifice 8, two logical screw-in cartridge valve 9, one-way throttle valves 10 and far transfer valve 11; Said side valve body 1-2 is arranged on main valve body 1-1 side, and the said first solenoid directional control valve 2-1 and the second solenoid directional control valve 2-2 are arranged on side valve body 1-2 side, and it is inboard that said safety valve 3 is installed in main valve body 1-1; The said first ball valve 5-1 is arranged on above the main valve body 1-1; The said second ball valve 5-2 is arranged on main valve body 1-1 side, and the said first ball valve 5-1 and the second ball valve 5-2 are Solenoid ball valve, and this patent ball valve can adopt Solenoid ball valve; Also can adopt other forms of ball valve; Producer can select as required, and said back pressure valve 4 is arranged on main valve body 1-1 opposite side, and said two logical screw-in cartridge valves 9 are arranged in the main valve body 1-1; Said accent valve 11 far away is arranged on the two logical screw-in cartridge valves 9; The said second throttle orifice 6-2 is arranged between accent valve 11 far away and the two logical screw-in cartridge valves 9, and said one-way valve 7, outer throttle orifice 8 and one-way throttle valve 10 are arranged on the main valve body 1-1 outside, and said first segment discharge orifice 6-1 is provided with accent valve far away 11 sides.
