In the whole steel grating production, there are two most critical processes: pressure welding and shearing. Steel grating cutting is one of the indispensable links. The steel grating must be accurate in the cutting process to minimize the cutting error. Accurate cutting can greatly save cutting time, improve work efficiency, and reduce the waste of materials in the cutting process of steel gratings. The most commonly used cutting methods in production are roughly divided into two types: sawing and shearing. High shear production efficiency and low material loss. The sawing efficiency is low and the loss is large. Let's talk about the cutting technology of galvanized steel grating in detail.
Mobile Circular Cold Saw
Most steel grating manufacturers use mobile disc cold saws as cutting machines for steel grating products. This cutting machine can arbitrarily cut galvanized steel gratings horizontally and maintain the orderliness of the cutting parts. The cutting method of the circular cold saw is sawing, which can make the broken section smoother, and no rough marks can be seen. Its working process is specifically refined as follows: when the circular saw blade (cutting blade) is installed on the high-speed rotating spindle, the motor exerts kinetic energy to promote the circular saw surface to rotate, which can reach about 10,000 rpm. 3-5 km/min (cutting rate). At the same time of high-speed rotating motion, the other side is also doing feeding motion. Usually, under the influence of this force, the part of the steel grating to be cut will be cut off in one piece, and the smoothness of the fractured section will be ensured. . It has the advantages of good cutting effect of steel grating, long service life of saw blade and easy maintenance.
New type steel grating automatic flame cutting machine
The new automatic flame cutting machine for steel grating has made a new breakthrough in the traditional technology. The X-axis track and Y-axis track are set on the frame, and the motion control system is also set on the frame. One end of the X-axis track is connected with a cutting nozzle. And the cutting head of the position detection identifier, the cutting head is connected with the Z-axis track. The novel flame cutting machine cuts steel gratings in special shapes, which significantly reduces the labor intensity of workers, improves work efficiency, ensures a good cutting effect, and reduces the waste of steel grating materials.
High-efficiency and energy-saving steel grating shears
In recent years, although there are various new cutting methods, such as electric spark method, laser method, ultrasonic method, electron beam cutting method and plasma, etc., considering the cost and practical application, the shearing method is still a research and The focus of the application. The new shearing method is a method developed by various countries. Japan, the United States, Germany, the United Kingdom, France and Italy have developed and produced various shearing machine tools or shearing dies, which have improved some of the common shearing methods. defect. The research of shearing method and the development of shearing equipment have become hot issues of concern.
The successful development of high-efficiency and energy-saving steel grating shears can fundamentally change the current processing pattern of the steel grating industry. It is expected that after the formation of industrialized production, it will replace or partially replace the currently used circular cold sawing machine, so that the processing level of the entire industry will be raised to a higher level; at the same time, the quality of products can be improved.
The high-efficiency and energy-saving steel grating shearing machine replaces the original low-efficiency and high-energy-consumption equipment with high-efficiency and energy-saving products, saving a lot of energy for processing enterprises in the entire industry, and can completely improve the harsh environment of the processing workshop. A quiet and clean working environment is of good significance for realizing civilized production and optimizing the environment.
