an electric spark linear cutting machine governing mechanism of tension for improvement, is mainly used inwire cutting machine tool.
Background technology
Wire cutting machine tool; guarantee machining accuracy and the surface roughness of lathe; tension force constant and be steadily key when wire electrode runs; general lathe has wire feed and receives silk two part; namely certain tension force is produced by loading damping artificial between wire drawing wheel and straining pulley; the damping of artificial loading the first be electromagnetic type, load with magnetic powder brake or magnetic powder cluth.The second is electric motor type, and load with the speed difference receiving silk and wire feed two motor, these two kinds of modes are all feasible, is the basis producing identical tension.Here it is claimed to be opinion power.But depending merely on opinion power is difficult to constant, because wire electrode send length due to silk volume axial length and diameter constantly change and change, cause the silk wrapping in straining pulley place degree of tightness to differ, not only directly affect main constant tension with steady, and exacerbate the wearing and tearing of straining pulley.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide "
a kind of electric spark linear cutting machine governing mechanism of tension of improvement".Should
governor motionhaving reasonable in design, with low cost, is a kind of
easy to use, improve furtherconstant and the stationarity of wire electrode tension,
effective raisingthe machining accuracy of lathe and surface roughness
lathe governing mechanism of tension.
To achieve these goals, the present invention is achieved through the following technical solutions:
main technical scheme is, a kind of electric spark linear cutting machine governing mechanism of tension of improvement, comprise the main governing mechanism of tension be arranged near machine Z-axis, also comprise the secondary governing mechanism of tension be arranged between straining pulley and upper directive wheel.Described governing mechanism of tension comprises and is placed in escapement parts on bearing block and sensor element, and described escapement parts are primarily of extension spring, escapement, spring support, pivoted arm and rotating shaft composition, and described sensor element is primarily of Hall element and permanent magnet composition.Spring support is fixedly connected with bearing block, and the two ends of described extension spring are fixedly connected with escapement with spring support respectively, and the two ends of pivoted arm are rotationally connected with rotating shaft and escapement respectively; Described permanent magnet is fixed in rotating shaft, and Hall element is placed in the side of permanent magnet, and the output of Hall element regulates with wire feeding motor and is electrically connected, wire electrode through wire feed rolls, upper directive wheel, escapement to straining pulley to form time governing mechanism of tension.
Further technical scheme is,

Detailed description of the invention
Below by non-limiting example, set forth the present invention further, understand the present invention.
Embodiment
The present invention as shown in Figure 1, Figure 2, Figure 3 shows,
main technical scheme is, a kind of electric spark linear cutting machine governing mechanism of tension of improvement, comprise the main governing mechanism of tension be arranged near machine Z-axis, also comprise the secondary governing mechanism of tension be arranged between straining pulley and upper directive wheel.Described governing mechanism of tension comprises and is placed in escapement parts on bearing block and sensor element, and described escapement parts are primarily of extension spring, escapement, spring support, pivoted arm and rotating shaft composition, and described sensor element is primarily of Hall element and permanent magnet composition.Spring support is fixedly connected with bearing block, and the two ends of described extension spring are fixedly connected with escapement with spring support respectively, and the two ends of pivoted arm are rotationally connected with rotating shaft and escapement respectively; Described permanent magnet is fixed in rotating shaft, and Hall element is placed in the side of permanent magnet, and the output of Hall element regulates with wire feeding motor and is electrically connected, wire electrode through wire feed rolls, upper directive wheel, escapement to straining pulley to form time governing mechanism of tension.
describedits S pole of permanent magnet is arranged on the sensitive surface of Hall element close to arranging.
Described Hall element is CS3503 type.
This
lathe governing mechanism of tension tension adjustment stages is:
In opinion power
regulatebasis adds the balance of time tension force between previous stage wire feed silk volume and straining pulley, design balance mechanism, the rotating shaft of escapement is installed permanent magnet and Hall element, when adjusting swing arm and being horizontal, hall element output voltage is 2.5V, and when silk, to roll up the silk speed sent too fast, and escapement is sagging.Magnet deflects, and effective clearance increases, and hall element output voltage reduces, and is 1.5V; When silk, to roll up the silk speed sent excessively slow, and escapement rises.Magnet deflects, and effective clearance reduces, and hall element output voltage increases, and is 3.5V; Hall element institute output voltage is fed back to wire feeding motor to regulate wire feed rate, realizes the balance of time tension force between silk volume and straining pulley.
