Steel drawing is a process of plastic metalworking in which a deformable workpiece changes its shape and cross-sectional area by pulling it through the hole of the corresponding tool or between rolls. This is usually a cold treatment. Drawing is used to produce mainly rods, wires and pipes. Let's take a look at the basic drawing tool, as well as the phases in the wire drawing process.Types of Wire strings
Before moving on to the topic of operations in the drawing process, let's talk a little about the main tools for steel drawing – tractors. They are made of tool steels. We can systematize the thrust because of the design, the number of so-called folds implemented in one thrust, and because of the movements performed during operation. Thus, we have monolithic tractors, also called lugs, folding (segmented) and roller tractors; single-stage and multi-stage tractors; fixed and mobile tractors. It is also possible to add separation by maintaining lubrication pressure - separation into tractors with hydrostatic lubrication and with hydrodynamic lubrication. The crushing zone can have various shapes, and hoods with the same cone-shaped zone are most often used.Phases in the steel drawing process
The first step is to tighten the wire, cut off its end to pass it through the rod. The next step is called wire tightening. This is the passage of material through a device that directs it to thrust. The wire is stretched, the traction is seized by a traction chain, which is attached to the winding drum. There is a stretching of several meters of wire and an adjustment of the drawing speed, as well as tension and lock nuts. The chain is disconnected, and the wire is attached directly to the tractor drum. After these actions, you can start the tractor in automatic mode. The made circles of steel wire are connected by welding the end of the end wire with the beginning of the wire of the next circle. It is also worth adding that the clean surface of the wire is ensured by cleaning the wire rod by shot blasting.Metalworking is indeed an extremely extensive topic, so there are many extensive scientific publications on this topic and beyond. It's worth looking into them to learn something about seemingly simple steel products, because these are often interesting processes.
