The structure of the guiding block is rather simple, so the special wire-guiding block need not be made, and the manufacturing difficulty and costs are reduced. 4. The electrode wire is very convenient when being positioned in the guiding groove and the original difficulty of wire threading can be avoided.
Description
Technical field
The utility model relates to a kind of electric spark linear cutting machine.
Background technology
In electric spark linear cutting machine,, make that wire electrode has play in fortune silk process or oscillation phenomenon takes place, especially the wire electrode outside the processing district owing to reasons such as the damage of wire electrode, the kinematic accuracy of transporting silk device and system's control accuracies.When the wire electrode that has play or vibration enters into the processing district, will have a strong impact on the stability of the wire electrode in the processing district, thereby influence the cutting processing precision of lathe.In order to eliminate or to weaken play or the vibration that is had when wire electrode 9 enters the processing district, need respectively to add a guide wire apparatus at the two ends of processing district for this reason.General formula seal wire piece 1 (Fig. 1, Fig. 2), additional guide wheel 3 forms such as (Fig. 3) faced directly that adopt in the existing guide wire apparatus.
As shown in Figure 1, in the guide wire apparatus of facing formula seal wire piece directly, when wire electrode from non-processing district when facing formula seal wire piece directly and enter into the processing district, because the seal wire piece has the effect of certain spacing and power to wire electrode, play or vibration that wire electrode is brought outside the processing district time have been weakened to a certain extent, but because wire electrode all is envelope modes with two medial surfaces of facing formula seal wire piece directly, and wire electrode is after discharge, its surface will produce many grooves not of uniform size, see Fig. 2, when the wire electrode of surface irregularity passes through the seal wire piece in an envelope mode, will produce a vibration source, thereby influence the stability of the wire electrode in the processing district.In addition, wire electrode forms a bending at the two ends of envelope point, and radius of curvature that should bending is less, so wire electrode can produce the stress concentration phenomenon at envelope point place, simultaneously because suffered stress is alternate stress, make wire electrode can produce the fatigue failure phenomenon, thereby influence the service life of wire electrode.
As shown in Figure 3, in the guide wire apparatus that adopts additional guide wheel, when wire electrode from non-processing district when additional guide wheel enters into the processing district, additional guide wheel has weakened play or the vibration that wire electrode is brought outside the processing district time equally to a certain extent.The envelope mode section of the being envelope mode of wire electrode and additional guide wheel, section envelope mode has increased the bending curvature radius at envelope section place, thereby has improved the stress concentration phenomenon.And along with the increase of envelope segment length, effectively homogenize the surface irregularity value of wire electrode, thereby improved the surface irregularity adverse effect of wire electrode.But because additional guide wheel is a dynamic body, can be a vibration source equally, and since the width of guide wheel V-type trench bottom transition arc greater than the diameter of wire electrode, so that additional guide wheel can not carry out both sides to wire electrode is spacing, be that wire electrode can rock to two sides, still can not effectively eliminate the play of motor silk.In addition, because the radius of additional guide wheel is subjected to the restriction of locus, the length of above-mentioned envelope section also can be restricted.
The inventor improves at the defective of above-mentioned seal wire piece, electric spark linear cutting machine as the disclosed employing curved surface of Chinese patent literature CN1762630A guide wire apparatus 2, see Fig. 4, though it can major part weakens or eliminate play or the vibration that is had when wire electrode enters the processing district, but because wire electrode still is directly contact with contacting of guide wire apparatus, it is by spacing play or the vibration that limits or eliminate wire electrode to wire electrode, therefore because the reaction force between wire electrode and guide wire apparatus, wire electrode still can be shaken, and this guide wire apparatus is made more complicated.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and a kind of electric spark linear cutting machine is provided, make it can weaken or eliminate wire electrode effectively and add play or the vibration that brings man-hour, thereby guarantee the stability of the wire electrode in the processing district, to improve the machining accuracy of electric spark linear cutting machine.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Electric spark linear cutting machine, two guide wire apparatus up and down that comprise wire electrode and leading electrode silk, it is characterized in that: between two guide wire apparatus one bootstrap block is set about described, open a groove on the bootstrap block, wire electrode passes this groove and does not contact with bootstrap block, and required gap is detained for forming cutting liquid in the gap of wire electrode and trough rim.
Compared with prior art, advantage of the present utility model is:
1, because bootstrap block does not contact with wire electrode, therefore avoids producing new vibration source, eliminate wire electrode and produce new play or vibration.
When 2, wire electrode is worked, because cutting liquid is sprayed on the wire electrode, between wire electrode and bootstrap block, be detained, the cutting liquid that is detained can limit the play of wire electrode, therefore can eliminate or weaken play or the vibration that is had when wire electrode enters the processing district effectively, guarantee the stability of the wire electrode in the processing district.
3, bootstrap block is relatively simple for structure, therefore need not make special seal wire piece, has reduced manufacture difficulty and cost.
4, wire electrode places guiding groove very convenient, has avoided originally wearing the difficulty of silk.
