Embodiment

[0045] At present, traditional steel pipe processing cannot produce small-diameter steel pipes (such as 15mm, 20mm, or 18mm diameter steel pipes) at one time. To manufacture small-diameter steel pipes, multiple processing is required. The smaller the diameter, the more processing times For example, if you want to get a 20mm steel pipe, you need to process the capillary into a 25mm steel pipe first, and then carry out cold rolling and stretching, so that the 25mm steel pipe can be processed into a 20mm steel pipe; and to get a 15mm steel pipe, you need to On the basis of 20mm, cold rolling and stretching are carried out again; this results in more intermediate passes for processing small-diameter steel pipes, which increases the number of necessary processes such as pickling, phosphating, saponification, and annealing, resulting in lower processing efficiency, and Increased labor costs and environmental pollution; therefore, this embodiment provides a steel rod roll, which can p...

Abstract

The invention discloses a steel pipe roller and a steel pipe machining method. Machining curved surfaces of different curvatures can be obtained by changing the machining outer diameter of a hole-shaped section positioning line on a roller body, so that a larger extension coefficient can be obtained, and therefore, a tubular billet can be machined into a small-caliber steel pipe at a time, therefore, intermediate passes in the machining process of the small-caliber steel pipe are reduced, necessary procedures such as acid pickling, phosphorization, saponification and annealing are reduced, resource waste is reduced, cost is reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of steel pipe processing, and in particular relates to a steel pipe roll and a steel pipe processing method. Background technique [0002] Steel pipe not only has the purposes of conveying fluids, powdery solids, exchanging heat, manufacturing mechanical parts and containers, etc., it is also an economical steel, from people's daily utensils, furniture, water supply and drainage, air supply, ventilation and heating facilities to various agricultural machinery The manufacture of appliances, the development of underground resources, the guns, bullets, missiles and rockets used in national defense and aerospace are all inseparable from steel pipes; therefore, steel pipes have become one of the indispensable products in people's life and production. [0003] At present, the production process of steel pipes is to use cold rolling mills to produce low elongation coefficients. After obtaining semi-finished product...
