During the drawing operation of the straight-in wire drawing machine, the metal wire is wound from a reel for a certain number of turns, and then passes through the tuning roller and enters the next wire drawing die.
Due to uneven wear of the wire drawing die, fluctuations in motor speed, or other reasons, destroying the balance of metal flow per second will inevitably cause changes in wire tension.
This change is reflected as a small-spoke swing of the tuning roller, and the displacement current sensor converts the swing displacement of the tuning roller into an electrical signal.
At the same time, as the production process continues, the relevant information is collected through data, and after certain calculations, the speed given value of the frequency converter is appropriately adjusted to achieve the purpose of matching the speed of the front and rear drums.
The rotation speed of the finished reel is the pilot speed, which is the soul of controlling the speed of the entire straight-in wire drawing machine and plays a role in connecting the past and the future.
The tuning roller of the finished reel controls the speed of the previous reel, and the tuning roller of the previous reel controls the speed of the previous reel, and so on.
In actual production, the straight-in wire drawing machine has stable and reliable performance. It not only has good wire drawing quality, but also has no bending or twisting.
Coupled with the strong cooling method, the work hardening rate of the steel wire is very low, it has excellent toughness and plasticity, the strength fluctuation range is small, and the product performance is stable. These excellent characteristics can be better reflected by users in the next process. to
Considering the actual effect, the use of the straight-in wire drawing machine not only improves the production efficiency but also produces obvious economic benefits for the users from the aspects of power consumption, qualification rate, yield rate, production efficiency, etc. It has excellent cost performance, so it is favored by the majority of users.
It should be noted that to give full play to the good performance of the straight wire drawing machine, it is necessary to properly treat the surface of the blank, and work hard on the hole design of the mold, the selection of high-speed lubricant, and vibration reduction measures.
In addition, determining the metal deformation speed is also a critical link.
