Galvanized steel pipe manufacturing and machining cut-off machine

Abstract

The invention relates to a galvanized steel pipe manufacturing and machining cut-off machine which comprises a mounting frame, a clamping assembly and a cutting assembly. A sliding groove A is formed in the mounting frame, the clamping assembly is mounted on the mounting frame, the cutting assembly is arranged at the upper end of the clamping assembly, and the cutting assembly is fixedly mounted on the mounting frame. The galvanized steel pipe manufacturing and machining cut-off machine provided by the invention can solve the following problems when an existing galvanized steel pipe is cut: a, when the existing galvanized steel pipe is cut, the position of the galvanized steel pipe is deviated due to shaking of the galvanized steel pipe, the galvanized steel pipe cannot be cut off through primary cutting, and then secondary cutting is carried out, so that the cutting efficiency is greatly reduced, and the production is influenced; and b, when the existing galvanized steel pipe is cut, a cutting blade is often damaged due to excessive heating, and then manual replacement is needed, so that the cost is greatly increased.

Problems solved by technology

[0002] Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dip galvanized steel pipes. Cold-galvanized steel pipes have been banned. Galvanized steel pipes have hot-dip or electro-galvanized welded steel pipes on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend Service life, galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heating for chemical coking equipment. Pipes used for condensers, condensing coolers, coal distillation wash oil exchangers, trestle piles, support frames for mine tunnels, etc. Hot-dip galvanized pipes are made by reacting molten metal with an iron substrate to produce an alloy layer, so that the substrate and coating The combination of the two, hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is carried out in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride. After cleaning, it is sent to the hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel pipe substrate and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant coating. The zinc-iron alloy layer with tight structure, the alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so it has strong corrosion resistance. In order to meet different use requirements, the existing galvanized steel pipes often need to be galvanized Steel pipes are cut, but the existing galvanized steel pipes still have certain deficiencies when they are cut.

[0003] Existing galvanized steel pipes often have the following problems when cutting: a: when the existing galvanized steel pipes are cut, the position of the galvanized steel pipes often deviates due to the rocking of the galvanized steel pipes, causing the galvanized steel pipes to deviate. The steel pipe cannot be cut in one cut, and then the second cut is performed, which greatly slows down the cutting efficiency and affects the production; b: When cutting the existing galvanized steel pipe, the cutting blade is often damaged due to excessive heat , which in turn requires manual replacement, which greatly increases the cost
