The cutting of the steel in the steel structure of the C-shaped steel machine should be carried out on the shearing machine or on the sawing machine as much as possible. Especially for the thin-walled steel roof truss, due to the accurate cutting requirements, the electric sawing method can be used, which not only has high work efficiency, but also has a smooth section. Flat, good quality, length error can be controlled within ±1mm. If there is no equipment, gas cutting can also be used. In order to improve the quality of gas cutting, a small-caliber nozzle should be used, and after the cutting, the hammer is gently tapped to make the slit flat to remove the slag and ensure the welding quality.
The manufacturing process of light steel structures is not very different from ordinary steel structures. The light steel structure has small material specifications, thin and thin rods, and the materials are straightened, unloaded, bent, processed and assembled, and the parts are easily turned over. It does not require large special equipment, so it is especially suitable for small and medium-sized factories. Manufacturing. The light steel structural members of round steel and small angle steel are thin and easy to form, which is an advantageous condition for processing and manufacturing. However, it is easy to cause bending and damage of the rod during the processing. Such bending and damage have a great influence on the bearing capacity of the structure, and attention should be paid during processing.
The use of cold-formed thin-walled steel structures generally requires a pickling, rusting or pickling phosphating process than ordinary steel structures. When the two channel steels are welded into a square tube, the welding amount is large. Since the rod connection is mostly topped, the accuracy of the blanking is required to be slightly higher. In the past, people have worried that the wall thickness of cold-formed thin-walled steel members is thin, and the straightening of materials is not easy, but it has been proved that the straightening process is easier to master than ordinary steel structures. Usually, the straightening machine is used to straighten and hammer the hammer on the platform. The former is easy to adjust and the quality can be ensured. Production operation of the tile machine;
