with the normal operation of wire cutting, the molybdenum wire 12 is worn to a certain extent, at this time, the diameter of the molybdenum wire 12 becomes smaller, and the molybdenum wire 12 is loosened to a certain extent, but in the actual processing process, the cooling water in the winding assembly 13 can enter the power tank 133 at the lower side and is discharged through the water outlet 134 at the bottom end to cool the molybdenum wire 12 continuously, meanwhile, when the cooling water enters the power tank 133, the impeller 135 can be impacted and drive the impeller 135 to rotate, at this time, the main shaft 136 rotates with it and drives the first transmission shaft 137 at the outer side thereof to rotate, and the first transmission shaft 137 drives the second transmission shaft 138 to rotate through the belt 139, at this time, the winding roller rotates with it to wind the molybdenum wire 12 at the outer side of the winding roller 1310 until the winding roller 1310 cannot rotate, so that the tightness state of the molybdenum wire 12 can be maintained, and the loosening phenomenon can be avoided.
Before the molybdenum wire is processed by the wire cutting machine, the molybdenum wire is kept in a tensioned state by the wire moving mechanism 4, and is still kept in a tensioned state after the molybdenum wire is worn and wound by the winding roller 1310.
The rotating speed of the impeller 135 is related to the flow rate of the cooling liquid, wherein the flow rate of the cooling liquid is controlled by a proportional valve, when the flow rate of the cooling liquid is low, the rotating speed of the impeller 135 is low, namely, the rotating speed of the impeller 135 is in direct proportion to the flow rate of the cooling liquid, the torque of the impeller 135 is in direct inverse proportion to the rotating speed of the impeller 135, namely, the faster the impeller 135 rotates, the smaller the torque value is, and the larger the torque value is, the impeller torque value ranges from 6NM to 8NM, namely, the maximum torque value is 8NM, and the minimum torque value is 6NM.
The cooling water used by the wire cutting is recycled, the flowing cooling water is converted into rotating power, the rotation of the winding roller 1310 is finally driven through the rotation of the belt 139, the molybdenum wire 12 is continuously wound to be always kept in a tight state, the winding roller 1310 can move in a rotating mode only by continuously starting a water pump during machining, namely, the continuous output of the cooling water is realized, the tightness state of the molybdenum wire 12 is kept, the problem that the electrode wire is loosened due to the abrasion of the electrode wire in a traditional device after being machined for a period of time is avoided, the problem of stopping adjustment when the electrode wire is loosened is avoided, the maintenance times in the machining process are effectively reduced, and the machining efficiency is further improved.

before the device is used, a corresponding drawing is input through a control device of the device, the program enables the device to operate according to the program, meanwhile, a workpiece to be machined needs to be fixed above a workbench 8 through a special fixture, meanwhile, a molybdenum wire 12 can be discharged by a wire feeding mechanism 4 to realize wire feeding, meanwhile, a bottom movable block 7 at the bottom end of the molybdenum wire 12 can be driven by a liquid supply system 5 to move left and right, at the moment, the bottom movable block 7 can move relative to a clamping groove 6, and a corresponding pulse device is started, so that the workpiece above the workbench 8 can be subjected to wire cutting machining;
before the online cutting process, the verticality of the molybdenum wire 12 needs to be adjusted, at the moment, cooling water can be discharged through the liquid supply system 5 and enters the interior of the adjusting pipe 152 through the liquid inlet valve 156, at the moment, a valve of the liquid discharge valve 157 is closed, the cooling water can only displace towards the left side after entering the interior of the adjusting pipe 152, pressure is applied to the right end of the piston plate 154, at the moment, the reset spring 153 at the left end of the piston plate 154 is compressed, and drives the piston plate 154 and the extension seat 155 to displace towards the left side, because one end of the extension seat 155 is connected with the connecting rod 158 and the connecting rod 158 is connected with the sliding block 159, the sliding block 159 can only displace relative to the limiting groove 14, when the extension seat 155 displaces towards the left side, at the moment, the two connecting rods 158 deflect immediately, the included angle between the two connecting rods 158 is further driven to displace relative to the limiting groove 14, at the moment, the two sliding blocks 159 can approach relatively, at the same time, the extension rod 1510 and the limiting disc 1511 can approach relatively, when the ends of the two limiting discs 1 contact with each other, at the other, the two semicircular through grooves are combined into a circular groove, the molybdenum wire 12, the verticality adjustment groove can be kept, the laser ranging instrument can be synchronously monitored, and the molybdenum wire 12, the molybdenum wire can be synchronously, the molybdenum wire ranging instrument can be started, and the laser ranging instrument can be used for measuring the molybdenum wire 12, and the molybdenum wire ranging instrument can be synchronously, and the range finder for measuring process of the molybdenum wire 12 is started;
with the normal operation of the wire cutting process, the molybdenum wire 12 is worn to a certain extent, at this time, the diameter of the molybdenum wire 12 is reduced, and the molybdenum wire 12 is loosened to a certain extent, but in the actual process, the cooling water inside the winding assembly 13 can enter the power tank 133 below and is discharged through the water outlet 134 at the bottom end to cool the molybdenum wire 12 continuously, meanwhile, when the cooling water enters the power tank 133, the impeller 135 can be impacted and drive the impeller 135 to rotate, at this time, the main shaft 136 rotates along with the rotation and drives the first transmission shaft 137 on the outer side surface thereof to rotate, and the first transmission shaft 137 drives the second transmission shaft 138 to rotate through the belt 139, at this time, the winding roller 1310 rotates along with the rotation to wind the molybdenum wire 12 on the outer side surface thereof until the winding roller 1310 cannot rotate, so that the tightness state of the molybdenum wire 12 can be maintained, and the loosening phenomenon can be avoided.
