Perforating machine for producing seamless steel tube

Abstract

The invention relates to the technical field of seamless steel tube production equipment, in particular to a perforating machine for producing a seamless steel tube. The perforating machine comprises an upper roller positioned on the upper surface of the seamless steel tube, a lower roller positioned on the lower surface of the seamless steel tube, a front guide disc positioned on the front surface of the seamless steel tube and a rear guide disc positioned on the rear surface of the seamless steel tube, wherein the upper roller and the lower roller are arranged in a mirror image mode, and the front guide disc and the rear guide disc are arranged in the mirror image mode; a perforating mechanism is inserted in a cavity on the right side of the seamless steel tube, the perforating mechanism comprises a top rod for applying pressure to the perforating mechanism by a pressure mechanism, a top head is fixedly mounted at the left end of the top rod, and a chip removal gap is formed between the perforating mechanism and the cavity on the right side of the seamless steel tube. The perforating machine for producing the seamless steel tube is compact in structure and high in perforating efficiency, and the inner bore shape and size of the obtained seamless steel tube meet the technological requirements.

Description

technical field [0001] The invention relates to the technical field of seamless steel pipe production equipment, in particular to a piercer for producing seamless steel pipes. Background technique [0002] Seamless steel pipes have a hollow cross-section and are widely used as pipes for transporting fluids, such as transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, seamless steel pipes are lighter in weight under the same flexural and torsional strength; at the same time, seamless steel pipes are also widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes , automobile transmission shaft, bicycle frame and steel scaffolding used in construction, etc., the material utilization rate is high, the manufacturing process is simple, and the processing time is reduced. [0003] It is precisely because of the particularity of the use of seamless steel pipes that various produc...

Problems solved by technology

[0003] It is precisely because of the particularity of the use of seamless steel pipes that various production equipment are required in the production process of seamless steel pipes. The piercing machine is a very important type of equipment for the production of seamless steel pipes. However, the existing large The structure of most piercing machines is relatively complex, the maintenance cost is high, and the shape and size of the piercing cannot meet the process requirements; at the same time, the phenomenon of blockage often occurs during piercing, which seriously affects the efficiency of piercing
