Abstract
The utility model relates to a composite electrohydraulic driver of a bender, and belongs to the technical field of digital control benders. The utility model comprises oil cylinders arranged on both sides of a slider, and pistons in the cylinders. The utility model is characterized in that each cylinder of the driver is provided with an oil tank on one side; an oil pump arranged in the oil tank is driven by a servomotor which is fixed outside the oil tank; a flowline is arranged between the oil pump and the cylinder; the flowline is connected with a reversal valve inside. The utility model drives the oil pumps in the oil tanks through the servomotors, and grating bars on both sides of the slider test the position and the speed of the slider at a 1 ms unit. Under the action of associated circuits, the servomotors drive the oil pumps in the oil tanks to transport necessary oil for mechanical operation and no valve is needed for control so that energy dissipation in the original stand-by state can be reduced. The utility model has high practicality and visible economic benefit.
Description
Technical field
The utility model relates to a kind of electric-hydraulic combined driving device of bending machine, belongs to numerical control bender
Technical field.
Background technology
The numerical control bender of at present domestic and international extensive use, it is the CNC hydraulic press brake of upper dynamic, integrate Numeric Control Technology, servo and hydraulic technique, action by control valve drive left and right sides oil cylinder rise long with return, drive the entablature of machine in this process, be the slide block rise and fall, the synchronization action of entablature is to combine the feedback of the grating chi signal that is arranged on the oil cylinder both sides and the flow that proportioning valve sends, and finishes by Dutch Delem digital control system.CNC controls the opening of two valves of left and right oil cylinder, and if desired, in-oil cylinder flow can be reallocated by servo valve, and entablature vertical direction straight line is moved, and amount of movement is to be determined by the umber of pulse that newly records.Signal from the CNC controller becomes the action that hydraulic pressure signal comes control valve by servo valve, and each oil cylinder all has independently control loop, servo valve and the filling-valve of oneself in hydraulic system.This class numerical control bender is to the quality requirement height of oil, thereby the use cost height, and after the numerical control bender start, even if slide block when not working, pumping also can be sent certain oil mass, in work, energy consumption increases motor greatly all the time.
Summary of the invention
Even if the purpose of this utility model is that the slide block that exists at existing numerical control bending machine actuating device is not when working, pumping also can be sent certain oil mass, motor is worked all the time, energy consumption is big and to the high deficiency of the quality requirement of oil, when providing machinery to stop, pumping can not rotated, even necessary oil mass is also only sent in machinery pumping when action, can not cause a kind of electric-hydraulic combined driving device of bending machine of unnecessary energy waste.
The purpose of this utility model is achieved through the following technical solutions, a kind of electric-hydraulic combined driving device of bending machine, comprise the oil cylinder that is arranged on the slide block both sides, in-oil cylinder piston, each oil cylinder one side that it is characterized in that described device is provided with fuel tank, be arranged on the interior oil pump of fuel tank through establishing solid driven by servomotor, set out oil pipe between oil pump and the oil cylinder, be connected to reversal valve in the flowline in the fuel tank outside.
The utility model is by the oil pump in the driven by servomotor fuel tank that is provided with, slide block both sides grating chi is with the position and the speed of the unit testing slide block of every 1ms, under the effect of interlock circuit, oil pump in the driven by servomotor fuel tank is sent the oil mass of mechanical action necessity, must not control by valve, the energy waste under the former holding state be can save, very strong practicality and remarkable economic efficiency the utlity model has.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure, 1 slide block, 2 oil cylinders, 3 pistons, 4 flowlines, 5 reversal valves, 6 fuel tanks, 7 oil pumps, 8 filters, 9 oil return pipes, 10 servomotors.
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by symmetrically arranged oil cylinder 2, flowline 4, reversal valve 5, fuel tank 6, oil pump 7, filter 8, and oil return pipe 9, servomotor 10 constitutes.Oil cylinder 2 is arranged on the both sides of slide block 1, be connected flowline 4 between fuel tank 6 and the oil cylinder 2, connect flowline 4 on the cylinder body at piston 3 two ends of oil cylinder 2, serial connection reversal valve 5 in the flowline 4, oil pump 7 places in the fuel tank 6, and servomotor 10 places fuel tank 6 outsides, and drives the oil pump 7 in the fuel tank 6, oil pump 7 connects an end of oil return pipe 9, and the other end of oil return pipe 9 connects filter 8.Piston rod one end that piston 3 in two oil cylinders 2 connects is connected with slide block 1.
