Description

Large wire-storing cylinder low-rotate speed dual-covering wire-electrode cutting device

Technical field

The utility model relates to a kind of cutting processing device, relates in particular to a kind of large wire-storing cylinder low-rotate speed dual-covering wire-electrode cutting device.

Background technology

Traditional quick-wire-moving linear cutting machine comprises bed piece, cross saddle, goes up planker, wire storage tube and wire feeder, its wire storage tube supports by the fixed support of both sides, motor is fixed in the one side, thereby has limited the diameter of wire storage tube, thereby the diameter of wire storage tube is often less.Adopt the problem of the cutting processing device existence of minor diameter line tube row silk to be: because the silk tube is little, under the prerequisite that guarantees linear velocity, a tube rotating speed is inevitable very high; Vibration frequency is big; The remained shock that vibration source produces is also inevitable big, so the fineness on work piece surface will inevitably be low.Unequal and the rotating molybdenum filament device error of perpendicularity of water (flow) direction pressure makes work piece surface can produce tangible black and white strip and dark commutation vestige when adding rotating.

Summary of the invention

The purpose of this utility model is: overcome the above-mentioned defective of prior art, a kind of large wire-storing cylinder low-rotate speed dual-covering wire-electrode cutting device that silk is convenient, can improve processing work surface smoothness, simple in structure, working stability greatly that changes is provided.

The utility model is realized by following scheme: improve the structure of existing wire feeder, adopt single armed to hang the wire storage tube that, promptly be arranged at wire tube shaft seat one side, thereby be convenient to wrapping wire, greatly facilitate and change silk operation, and the wire storage tube diameter can increase, and not be subjected to the restriction in space.

The newly-increased simultaneously dual-covering circuit that formation dual-covering cut surface is arranged, by central processing unit, mode selection switch, a plurality of input gauge tap, input independent isolating device, output independent isolating amplifier, a plurality of control relay are formed.

The utility model has reduced impulsive force, and stable drive can improve the surface smoothness of workpiece to be machined greatly, and be convenient to wrapping wire, greatly facilitates to change the silk operation.

The specific embodiment

Contrasting accompanying drawing below in conjunction with embodiment is elaborated to the utility model.Embodiment:

Present embodiment comprises bed piece, cross saddle, last planker and wire feeder, wire feeder comprises buncher 1, wire storage tube 2, silk tube planker 3, wire tube shaft seat 4, wire tube shaft 5, the feed screw nut 6, wire screw mandrel 7,

synchronous pulley

8,9,10,11, silk tube base 12, wire storage tube 2 usefulness single armeds hang the wire storage tube that, and the wire storage tube diameter is 2 times of prior art silk tube, wire storage tube 2 is arranged at wire tube shaft seat 4 one sides, wire tube shaft 5 is positioned at and is arranged at wire storage tube 2, wire tube shaft seat 4 shaft core positions, motor 1 is positioned at wire tube shaft seat 4 tops, wire storage tube 2 adopts aluminium alloy, and weight reduction reduces running inertia, reversing impact power also reduces, and reaches the purpose that improves fineness.Under the prerequisite that guarantees the molybdenum filament linear velocity, the speed drop of silk tube is at half.The rotating speed of silk tube is the vibration source of molybdenum filament, and silk tube rotating speed is high more, and the frequency of vibration source is also big more, and the molybdenum filament amplitude is also big more, directly influences the line cutting fineness of workpiece.Have only the silk of increase tube diameter just can reduce rotating speed, reach the purpose that improves fineness.In circuit design, dispose the dual-covering circuit that forms the dual-covering cut surface, by central processor CPU, mode selection switch S, input gauge tap K1, K2, K3, K4, K5, K6, K7, input independent isolating device P1, output independent isolating amplifier P2, control relay J1, J2, J3 form.Input gauge tap K1, K2, K3, K4, K5, K6, K7 are connected to cpu data

line end pin

1,2,6,7,8,17,18 respectively through input independent isolating device P1, and cpu data

line end pin

9,10,11,10,13 amplifies independent isolating device P2 through output and is connected to control relay J1, J2, J3 and exchange system respectively.CPU handles through internal calculation by accepting each the road input signal from gauge tap K1-K7, and each road of output corresponding control signals is electric.K1 boiling water switch pump wherein, K2 is the switch that cuts out the pump, K3 is a left lateral journey switch, K4 is a right lateral journey switch, and K5 is an emergency stop switch, and K6 is for closing the wire switch, K7 is the silk beginning of driving away, but each road input signal of input independent isolating device P1 independent process, and the output corresponding control signal also makes the front and back electrical isolation.Output independent isolating amplifier P2 can handle each the road signal from CPU respectively, and amplifies promotion back, back one-level circuit, simultaneously with electric before and after isolating.J1 is a water pump relay line bag, and J2 is a wire relay line bag, and J3 is for opening high frequency relay line bag, and mode selection switch S can switch between fast wire pattern of tradition and dual-covering pattern.
