In the process of the pulley wire drawing machine design, we all have certain goals. To a certain extent, we need to achieve certain expected functional requirements through design. So when doing the design work, we focus on this Issues related to this aspect are introduced.

When the pulley wire drawing machine is designing, the issues that need to be considered are very clear, which to a certain extent mainly include process requirements and usage requirements. The so-called design principle mainly refers to the specific mechanical function requirements of the equipment in the design task.

We need to achieve this goal by conceiving and selecting the working principle of the pulley wire drawing machine design or process methods. Obviously, we can use these methods to ensure the functionality of different devices.

We need to first select some corresponding actuators based on the process action process proposed in the functional principle scheme of the wire drawing machine equipment, as well as the motion law requirements of different process actions, etc.

In this case, after selecting the prime mover and transmission mechanism, The components are combined according to a certain order to form a schematic diagram of the movement of the equipment.

Due to the uninterrupted production of copper wire drawing equipment, the pulley wire drawing machine’s wire drawing speed will gradually become out of synchronization with the annealing, which will cause intermittent and irregular wire diameters due to the fast and slow traction speed during wire drawing.

The reasons for this change are as follows:

The tension on the wire storage wheel is unstable. There may be many places where air pressure is used in the production workshop, which will cause the air pressure of the air pump of the wire drawing machine to be high and low, which also makes the tension of the wire storage device not constant. Since the speed of taking up the wire is constant, this makes The pulling force on the wire drawing is also not constant, which can cause the outer diameter deviation of the single wire to be uncontrollable.
The vibration of copper wire on the annealing wheel. This causes the copper wire to be annealed in a state of looseness and tightness. The current density of the annealing is sometimes high and sometimes small. The strength of the copper wire at higher speeds is relatively low, so it is easy to cause the copper wire to spark on the annealing wheel. , making the surface of the copper wire uneven in diameter due to the action of sparks.
Wear of the main motor gearbox caused by long-term use. This can make the speed of the fixed speed wheel of wire drawing not match the traction speed and take-up speed, resulting in the thinning of the single wire.

Solution: In the pulley wire drawing machine design, lubricate the wire storage device well to avoid causing reverse friction on the wire during high-speed operation and thus thinning the wire; adjust the wire tension so that the wire drawing stroke is always close to the annealing wheel; Ensure the integrity of the annealing wheel steel ring to avoid unstable annealing current due to surface defects of the steel ring.
