Wear-resistant steel plates are widely used in various industries because of their excellent wear resistance. Taking the more basic shape as an example, different uses have different requirements for the shape of wear-resistant steel plates, so the wear-resistant steel plates need to be cut. Open processing. Among the many methods of cutting wear-resistant steel plates, in addition to the well-known hot cutting, there is also the cold cutting process.
In fact, whether it is hot cutting or cold cutting, the final effect is the same, only the principles, processes, operating methods and equipment used are different. There are several cold cutting methods, and we will introduce them one by one from these aspects.
1. Line incision
Wire cutting machines are mainly used to complete the cutting purpose. Generally, metal wires are used as tool electrodes, and pulse current flows between the metal wires and the workpiece. The pulse discharge point will play a corrosive effect, and applying this effect on the workpiece can complete the cutting work. This process is actually developed and improved on the basis of EDM drilling and forming, so it has replaced it in some aspects.
2. Shearing machine
This uses a relatively advanced equipment to complete the cutting of wear-resistant steel plates, that is, the use of shears. The shearing machine uses a moving upper blade and a fixed lower blade to apply a certain shearing force to metal plates of various thicknesses, and then effectively separate the plates according to the required dimensions. Because the shearing machine has a relatively high working efficiency, this cutting method is widely used in metal processing.
3. Ultra-high water pressure incision
Unexpectedly, water can also be used as a sharp tool to cut wear-resistant steel plates. Of course, this water is a high-energy water flow generated by multi-stage pressurization. It only needs to pass through an extremely fine nozzle to complete shearing with high-speed eruption. Work.
