Thread tubular pile production line with adjustable diameter and wall thickness

Abstract

The invention relates to a thread tubular pile production line with the adjustable diameter and wall thickness. The thread tubular pile production line is characterized in that the thread tubular pile production line is mainly composed of a feeding machine (1), an uncoiler (2), a clamping leveler (3), an edge milling machine (4), a pre-bending pressing plate device (5) and a molding machine; a steel strip roll enters the feeding machine (1) to be uncoiled by the uncoiler (2) and is then fed into the clamping leveler (3) to be transferred forwards for correction, a steel strip in a rolling state originally becomes the flat plate shape, then the steel strip roll enters the edge milling machine (4) to mill the two side edges into slope edges so as to facilitate final molding welding machining, the steel strip obtained after edge milling enters the pre-bending pressing plate device (5) to conduct upward pre-bending on the two side edges and enters a molding machine (6) under the effect of a pressing plate for rolling molding, and spiral joining seams formed in the rolling molding process are welded through internal and external welding equipment, wherein the internal welding equipment and the external welding equipment differ one spiral; and a plurality of electric vertical roller devices (7) for supporting are installed in the advancing direction and the two sides of the steel strip. The thread tubular pile production line is simple in structure, high in production effect and capable of achieving variable diameter and variable thickness.

Description

technical field [0001] The invention relates to a steel pipe production technology, in particular to a technology for producing threaded pipe piles with strip steel, in particular to a threaded pipe pile production line with adjustable diameter and wall thickness. Background technique [0002] As we all know, pipe piles began to be produced in Europe at the beginning of the 20th century, and were quickly widely used all over the world, especially in developed industrialized countries. In the 1950s, my country first imported and used it from the former Soviet Union by the Bridge Bureau of the Ministry of Railways in the construction of railway bridge cofferdams. Due to the influence of cheap land resources and human resources, and domestic production is basically in a blank state, the application and development of ultra-long pipe piles as metal building materials in my country is still very slow. With the rapid development of my country's economy, various fast, efficient an...
