Abstract
The utility model discloses a retarded constant-tension controller for an electrode wire of a fast-walking thread cutting machine tool. The utility model comprises a tension detector, a displaying and controlling circuit, a brake which is connected with an output terminal of the controlling circuit, wherein a band wheel is connected with an output shaft of the brake. After the utility model detects the tension of the electrode wire, the brake can brake the band wheel to adjust the tension. The utility model can display the tension of the electrode wire in an online way to quantize the tension. Simultaneously, the tension of the electrode wire is adjusted in an online mode, so the tension value of the electrode wire is kept to be constant to assure the processing accuracy of a machine tool.
Description
Technical field
The utility model belongs to tension adjusting device, is specifically related to a kind of tension adjusting device of electric spark quick-wire-moving linear cutting machine wire electrode.
Background technology
Quick-wire-moving linear cutting machine is the distinctive a kind of non-traditional machine tool with wire electrode fast turn-around and workpiece electric spark discharge machining of China.The initial tension size that the wire electrode wire electrode is installed in the prior art is that the degree of tightness that relies on finger to push the wire electrode sensation is judged the tension force size, and can not selects and set tension force.Because the size of existing tension force is judged by experience, in fact can not quantize to show, and is bigger to beginner's difficulty; Have the adjustment that in process, can't realize tension force now, but in the process, the change of wire electrode wire electrode tension directly influences machining accuracy.Descend in order to solve electrode wire anamorphic stretching tension force when working, way is to shut down usually at present, tightens up wire electrode.Cause the process instability like this, influence machined surface quality and precision, influence cutting efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of device that can adjust the quick-wire-moving linear cutting machine wire electrode tension, to address the above problem.
The technical solution of the utility model is: it comprises tension detector, shows and control circuit that it also comprises the brake that is connected with the control circuit output, and the output shaft of brake connects belt wheel.
Because when this device can realize that wire electrode is installed, the big I of initial tension had more process requirements and quantizes, sets, tension force can be regulated in setting range.Add man-hour, detect the tension force of wire electrode after, realize the adjustment of tension force by brake braking belt wheel.It can online show electrode silk tension force, tension value is quantized, simultaneously by the tension force of online adjustment wire electrode, make the tension value of wire electrode keep constant, thereby the machining accuracy of assurance lathe.
Description of drawings
Accompanying drawing quick-wire-moving linear cutting machine wire electrode retardance formula constant tension control device schematic diagram
The specific embodiment
As shown in drawings, the coiling of the wire electrode 10 of quick-wire-moving linear cutting machine comprises storage curled hair tube 2, guide wheel 1.On the device of existing wire electrode storage undrawn yarn, constant tension control device is set.Constant tension control device comprise with a guide wheel 1 on the tension detector 6 established, i.e. tension pick-up, the output of tension detector 6 connects tension force display 7; With tension controller 8, i.e. tension control circuit.The output of tension controller 8 connects control selector switch 9, and two outputs of control selector switch 9 are connected with brake 51,52 respectively.The output shaft of brake 51,52 connects belt wheel 41,42; Wire electrode 10 is walked around belt wheel 41,42.Also establish freely falling body escapement 10 on the wire electrode 10, freely falling body escapement 10 connects fork 3.
The tension adjustment principle of this device is: after recording tension variation by tension pick-up 6, this signal of telecommunication is delivered to tension controller 8, the electric control signal of tension controller 8 outputs is through control selector switch 9 backs or deliver to miniature magnetic powder brake 51, deliver to miniature magnetic powder brake 52, this is decided by to store up the direction of rotation of curled hair tube 2, storage curled hair tube 2 is just changeing, brake 52 work, and brake is not worked for No. 51; If 2 counter-rotatings of storage curled hair tube, brake 51 work, brake is not worked for No. 52.Thereby the size of regulating belt wheel 42 or 41 brake force reaches the size of the permanent tension force of wire electrode.Closed-loop control reaches permanent tension force purpose, and the big I of tension force is regulated arbitrarily.
