[0015] Beneficial effects of the present invention:

[0016] 1. The first and second wire drawing bodies of the present invention are both equipped with devices that can detect whether the copper wire is broken during the wire drawing process. During the continuous and stable wire drawing process, the copper wire passes through the detection wheel limit block from the bottom end of the detection wheel, and the copper wire will squeeze the bottom end of the detection wheel, so that the second sliding block is squeezed by the detection spring, so that the second sliding block can detect the pressure. When the pressure sensor cannot detect the squeezing force, and the laser ranging sensor detects that the distance between it and the detection plate is shortened to the lowest threshold, it means that the continuously drawn copper wire has been broken. At this time, timely detection and adjustment can be carried out. When the pressure detected by the pressure sensor is too large, it means that the tension of the drawn copper wire is too large. At this time, each first electric push rod is running, and the first electric push rod controls each first sliding block to slide up and down along the limit slot to adjust and control the position of the barrier limit of each rotating limit wheel, so that the tension of the copper wire passing through each rotating limit wheel can be conveniently adjusted, so that the tension of the pulled copper wire will not be too large to cause a break.

[0017] 2. The present invention can automatically detect whether serious friction occurs during the continuous drawing of copper wire and replenish lubricating oil in time. During the drawing process, when the copper wire passes through the drawing hole with a large degree of friction, the edge of the drawing hole will heat up rapidly. At this time, the temperature sensors distributed on both sides of the first drawing die or the second drawing die can accurately detect the temperature change and transmit the monitoring information to the externally connected controller, thereby controlling the operation of the oil replenishing part at the specified position. The fourth electric push rod in the oil replenishing part can control the lifting and adjusting plate to drive the installation adjustment frame to lift and adjust, and the motor can drive the rotating frame to rotate a specified angle so that the nozzle can be accurately aligned with the drawing hole that needs to be sprayed with lubricating oil. Then, the lubricating oil is transported to the rotating frame through the delivery connecting hose with the help of an externally arranged lubricating oil injection system and sprayed from the nozzle to the drawing hole, which plays a role in lubrication and cooling, and also makes the copper wire not easy to break during the drawing process, and can conveniently adjust and use the drawing holes of specified specifications during the drawing process.

At this time, the copper wire will squeeze the bottom end of the detection wheel 12, so that the second sliding block 13 is squeezed with the detection spring 16, so that the second sliding block 13 can detect pressure. When the pressure sensor 15 detects no When the extrusion force is reached, and at this time the laser ranging sensor 18 detects that the distance between it and the detection plate 17 is shortened to the lowest threshold value, it means that the continuously drawn copper wire has been broken.

Then, the lubricating oil is delivered to the rotating frame 34 through the delivery connecting hose 36 with the help of an externally arranged lubricating oil injection system and sprayed from the nozzle 33 to the drawing hole 21, which plays a role in lubrication and cooling, and also makes the copper wire less likely to break during the drawing process.

The nozzles 33 in the oil replenishing part 6 at different positions can realize the sufficient addition of lubricating liquid to the drawing holes 21 at different positions of the first wire drawing die 20 and the second wire drawing die 22.

[0036] The fixed splicing plates 4 in the first drawing body 1 and the second drawing body 2 are fixedly connected by bolts, so that the first drawing body 1 and the second drawing body 2 can be conveniently fixed and spliced ​​as needed, and the number of splicing of the first drawing body 1 and the second drawing body 2 can be conveniently adjusted and controlled.

[0037] Working principle: During use, the thick copper wire is led out from the wire-paying rack, and is transported after being blocked and limited by the rotating limiting wheels 10 evenly arranged at the front end of the limiting support plate 9, so that the wire body is pulled and passes through the inside of the second wire drawing die 22 or the drawing hole 21 of the specified specification on the first wire drawing die 20. The copper wire passes continuously through each drawing hole 21 in the first wire drawing body 1 and the second wire drawing body 2, undergoes plastic deformation, and its diameter decreases step by step. The number of first wire drawing bodies 1 and second wire drawing bodies 2 that are continuously spliced ​​and used can be freely assembled and matched according to needs. After being pulled through the drawing hole 21, it is again blocked and limited by the rotating limiting wheels 10 arranged at the end of the limiting support plate 9, and then squeezed by the bottom end of the detection wheel 12 to pass through. In the continuous and stable wire drawing process, the copper wire is blocked and passed by the bottom end of the detection wheel 12 by the detection wheel 12. At this time, the copper wire will pass through the detection wheel 12. 2 is squeezed, so that the second sliding block 13 is squeezed with the detection spring 16, so that the second sliding block 13 can detect the pressure. When the pressure sensor 15 cannot detect the squeezing force, and at this time the laser ranging sensor 18 detects that the distance between it and the detection plate 17 is shortened to the lowest threshold value, it means that the continuously drawn copper wire has been disconnected. At this time, timely detection and adjustment can be made. When the pressure detected by the pressure sensor 15 is too large, it means that the tension of the drawn copper wire is too large. At this time, each first electric push rod 19 is running, and the first electric push rod 19 controls each first sliding block 8 to slide up and down along the limit slot 11 to adjust and control the position of the blocking limit of each rotating limit wheel 10, so that the tension of the copper wire passing through each rotating limit wheel 10 can be conveniently adjusted, so that the tension of the pulled copper wire will not be too large to cause disconnection.

[0038] During the wire drawing process, according to the different requirements of copper wire drawing, the second wire drawing die 22 or the first wire drawing die 20 can be controlled to move down to the inside of the limit card 23 by starting the second electric push rod 26 or the third electric push rod 27. At this time, the second wire drawing die 22 or the first wire drawing die 20 moved to the inside of the limit card 23 can be used normally. The wire drawing holes 21 evenly opened on the first wire drawing die 20 and the second wire drawing die 22 have different specifications. Therefore, according to the needs of wire drawing, the wire drawing holes 21 of different specifications are adjusted to the area where the wire drawing work is carried out. During the wire drawing process, when the copper wire passes through the inside of the wire drawing hole 21 with a large degree of friction, the edge of the wire drawing hole 21 will heat up rapidly. At this time, the temperature distributed on both sides of the first drawing die 20 or the second drawing die 22 is The temperature sensor 28 can accurately detect temperature changes and transmit the monitoring information to the externally connected controller, thereby controlling the operation of the oil replenishing part 6 at the specified position.

Then, the lubricating oil is transported to the rotating frame 34 through the externally arranged lubricating oil injection system through the conveying connecting hose 36 and sprayed from the nozzle 33 to the drawing hole 21, which plays a role in lubrication and cooling, and also makes the copper wire not easy to break during the drawing process. The sprayed and dripping oil can be collected by the provided guide frame 24 and discharged through the discharge pipe at the bottom.
