Description
Technical field
The utility model relates to a kind of permanent tensioning apparatus, and the permanent tensioning apparatus of particularly a kind of wire electrode belongs to Wire EDM.
Background technology
Existing wire electrode moves back and forth the permanent tensioning apparatus of the wire electrode of using on the electric spark linear cutting machine mostly to be made up of silk tube, row's silk guide wheel, wire electrode, capstan etc., simple in structure.As everyone knows, because galvanic action, the tension force of wire electrode diminishes gradually, influences machining accuracy, and this is for the quite high product of requirement on machining accuracy, and this kind device is just too far behind to catch up.
Summary of the invention
The purpose of this utility model provides the permanent tensioning apparatus of the high wire electrode that is used for the reciprocating electric spark linear cutting machine of wire electrode of a kind of machining accuracy.
The utility model is achieved in that it comprises row's silk guide wheel, silk tube, transition guide wheel, upper and lower capstan, wire electrode, a pair of pulley, upper and lower constant torque spring, a pair of line slideway, two nylon ropes, a pair of sliding wheel also are installed between described row silk guide wheel and upper and lower capstan, one end of wherein said upper and lower constant torque spring joins with an end of two nylon ropes respectively, and the other end of two nylon ropes joins through a pair of pulley and a pair of sliding wheel.The other end of a pair of sliding wheel is attempted by a pair of line slideway, one end of one end of described wire electrode and described silk tube joins, and the other end joins through the other end of described a pair of row's silk guide wheel, a pair of transition guide wheel, a pair of sliding wheel, upper and lower capstan and described silk tube.
The permanent tensioning apparatus of wire electrode of the present utility model is owing to adopt said structure, so be to be symmetrical arranged installation up and down, thereby reciprocating wire electrode tension is consistent, original tension force that can keep wire electrode, can with the twisting force of constant torque spring on the guide wheel of accurate line slideway seat, therefore can improve the machining accuracy of product again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among Fig. 1: 1a, 1b, row's silk guide wheel 2a, 2b, pulley 3, go up constant torque spring 4, silk tube 5, down constant torque spring 6a, 6b, line slideway 7a, 7b, nylon rope 8a, 8b, transition guide wheel 9a, 9b, sliding wheel 10, go up capstan 11, wire electrode 12, capstan down
As shown in Figure 1, by row's silk guide wheel 1a, 1b, silk tube 4, transition guide wheel 8a, 8b, upper and lower capstan 10,12, wire electrode 11 and the pulley 2a, the 2b that between row's silk guide wheel 1a, 1b and upper and lower capstan 10,12, are provided with, upper and lower constant torque spring 3,5, line slideway 6a, 6b, nylon rope 7a, 7b, sliding wheel 9a, 9b have constituted the permanent tensioning apparatus of wire electrode.One end of last constant torque spring 3 is connected with the end of nylon rope 7a, the other end of nylon rope is connected back and sliding wheel 9a with pulley 2a a end joins, the other end of sliding wheel 9a and line slideway 6a also connect, one end of following constant torque spring 5 and the end of nylon rope 7b join, the other end of nylon rope 7b is connected back and sliding wheel 9b with pulley 2b a end joins, the other end of sliding wheel 9b and described line slideway 6b also connect, end with wire electrode 11 joins with an end of tube 4 again, the other end of wire electrode 11 is through row's silk guide wheel 1a, transition guide wheel 8a, sliding wheel 9a, last capstan 10, following capstan 12, sliding wheel 9b, transition guide wheel 8b, row's silk guide wheel 1b, the other end with silk tube 4 joins again, then this device is fixedly mounted on the coil holder up and down of lathe (not marking among the figure).Like this, wire electrode 11 is to begin through row's silk guide wheel 1a, a 1b from silk tube 4, and transition guide wheel 8a, 8b, sliding wheel 9a, 9b, upper and lower capstan 10,12 are again through sliding wheel 9a, 9b, and transition guide wheel 8a, 8b arrange silk guide wheel 1a, a 1b, get back to a tube 4.
In permanent tensioning apparatus, the torsion of constant torque spring 3,5 is transformed into the pulling force of nylon rope 7a, 7b, act on and be installed in line slideway 6a, sliding wheel 9a, 9b above the 6b, the continuous wire electrode 11 with elongation concentrates between transition guide wheel 8a and last capstan 10 and transition guide wheel 8b and the following capstan 12, thereby makes the wire electrode 11 of machining area keep constant tension force.In the process, when wire electrode 11 tension force diminish, because the effect of constant torque spring 3,5 makes nylon rope 7a, 7b pulling sliding wheel 9a, 9b be moved to the left along line slideway 6a, 6b, thereby makes wire electrode 11 keep original tension force.
This device (zone shown in the double dot dash line) is applicable to the reciprocating electric spark linear cutting machine of wire electrode.Because galvanic action, the tension force of wire electrode diminishes gradually, influences machining accuracy.
