Continuous roller type cold bending shaping method for metal sheet pile

Abstract

The invention relates to a continuous roll type cold-bending forming method for a steel sheet pile, including scrolling, continuous cold-bending forming and cutting; the method is characterized in that the continuous cold-bending forming refers to that the scrolled steel band is fed into a production line of a multi-pass continuous roll type cold-bending forming machine set for multi-pass continuous roll type cold-bending forming, a frame at each pass is provided with an upper rotation axis and a lower rotation axis which are equipped with inosculated dies, the upper rotation axis and the lower rotation axis rotate oppositely, one rotates along the clockwise direction, while the other rotates along anticlockwise direction; in this way, a scrolled steel plate moves forwards depending on friction force in the roll gap of rotation dies inosculated up and down after being well adjusted and enters the next pass for continue forming, when entering each pass for forming, the steel plate is forced to deform under the action of the inosculated dies, each pass completes setting forming amount, and the forming of the steel sheet pile is finally completed through a plurality of passes, thus rolling the products of the steel sheet pile in line with requirements. The method has the advantages of energy saving, environmental protection, high production efficiency and complete specification, length and size of products.

Description

technical field [0001] The invention relates to a production method of metal building materials, in particular to a cold-bending manufacturing method of steel sheet piles, in particular to a connecting roll-type cold-bending forming method of steel sheet piles. Background technique [0002] Steel sheet 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 steel sheet piles as metal building materials in my country is still very slow. With the rapid development of my country's economy, various fast, efficient and environmentall...
