The course of work：
Silk is carried out first, and wire electrode comes out the manual screwing apparatus for passing sequentially through and being arranged on and reaching the standard grade on arm 100 from silk cylinder 310
Structure 150, stator ring 105, the first automatic tensioning mechanism 140, sliding equipment 130, tension sensor 120, stator ring 105,
Second automatic tensioning mechanism 110 and stator ring 105, then pass sequentially through be arranged on offline arm 200 stator ring 105,
Second automatic tensioning mechanism 110, stator ring 105, tension sensor 120, sliding equipment 130, the first automatic tensioning mechanism
140th, stator ring 105 and manual tensioning mechanism 150, are eventually returned on silk cylinder 310.
During work, when the tension force guide wheel 111 on the first automatic tensioning mechanism 140 detects that tension force deviates setting value,
The output signal of power guide wheel 111, the first motor 117 of automatic tensioning mechanism 140 are started working, and drive screw mandrel 112 to rotate, and screw mandrel
112 setting in motions of the first sliding block 113 being connected.Because tension force guide wheel 111 is connected by bearing and the first sliding block 113, when
When first sliding block 113 moves, the synchronizing moving of tension force guide wheel 111.
When tight silk, tension force guide wheel 111 is moved to the left, and drives sliding equipment 130 to move down by connecting rod 104 and 103,
Molybdenum filament tenses；On the contrary, when loose wire, tension force guide wheel 111 moves right, and now drives sliding equipment by connecting rod 104 and 103
130 move upwards, and molybdenum filament starts to relax.
Second automatic tensioning mechanism 110 is identical with the first automatic structure of tensioning mechanism 140, and simply tight wire rows journey is different.Together
When the second automatic tensioning mechanism 110 controlled by tension sensor 120, when tension sensor 120 detect tension force deviate setting value
When, output signal, the first motor 117 of the second automatic tensioning mechanism 110 is started working, and drive screw 112 is for linear motion, and
The first sliding block 113 that screw mandrel 112 is connected starts to move.Because tension force guide wheel 111 passes through the sliding block 113 of bearing 115 and first
Connection, when the first sliding block 113 moves, the also synchronizing moving of tension force guide wheel 111；The motion of tension force guide wheel 111 will be to electricity thereon
Polar filament is tensed or loosened, and thus can adjust the tightness of molybdenum filament, the tension force of tension sensor 120 is reached setting
Value.
After the completion of wire cutting, when cut-out recovery is carried out to molybdenum filament, any silk on spanner turn cut-out location-plate 3151 is used
Bar 3154, and the sliding block 3155 that the screw mandrel 3154 coordinates will be moved up and down radially, the conelet being fixedly connected with screw mandrel 3154
Gear 3153 rotates, and due to bevel pinion 3153 and the engagement connection of bevel gear wheel 3152, therefore drives bevel gear wheel 3152 to rotate,
Bevel gear wheel 3152 drives other two bevel pinions 3153 for being engaged with connection thereon to rotate simultaneously, two bevel pinions
3153 drive the screw mandrel being attached thereto to rotate respectively again, and screw mandrel drives sliding block thereon to move radially, so as to realize on silk cylinder
Three convex swords 3134 of cutting knife synchronously move radially, and the recessed sword 3133 of cutting knife and the convex sword 3134 of cutting knife are engaged cooperation, and molybdenum filament is entered
Row is cut off, and the molybdenum filament on silk cylinder can be cut into three sections by the convex sword 3134 of three cutting knifes on silk cylinder around distribution.
Then, any screw mandrel 3154 compressed on location-plate 3156 is rotated, similarly, realizes three depression bars 3131 on silk cylinder
Synchronous radial motion, cut off on silk cylinder three sections of molybdenum filaments are pressed on silk cylinder 313.Silk device 3132 is received to pass through on depression bar 3131
Strip groove and silk cylinder 313 on guide groove 3135 coordinate movement, realized using the groove received on silk device to cut-out molybdenum filament
