Heavy-duty steel plate warehouse rotary forming manufacturing system

Abstract

The invention discloses a swing-up forming manufacturing system for a heavy steel plate silo. The swing-up forming manufacturing system comprises a plurality of stand columns arrayed at intervals in the peripheral direction. The adjacent stand columns are connected into a whole through frames to form a circular supporting frame. Seven bending machines and seven seam closing machines are arrayed in the circular supporting frame in the arc direction. A steel plate roll feeding plate is arranged on one side of the first bending machine. The swing-up forming manufacturing system has the advantage of being designed for the swing-up forming type steel plate silo of steel plates with the width larger than 750 mm and the thickness larger than 5 mm. In order to solve the problem that in the manufacturing process of the swing-up forming type steel plate silo, the width and the thickness of the steel plates with the upper edges and the lower edges to be bent and seams to be closed are large, seven continuous bending producers and seven continuous seam closing procedures are carried out, the bending and seam closing quality of the large swing-up forming type steel plate silo is guaranteed, and the production and manufacturing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a spin-up forming steel plate warehouse, in particular to a heavy-duty steel plate warehouse spin-up forming manufacturing system. Background technique [0002] The rotary forming steel plate warehouse is widely used in cement, fly ash, grain processing, chemical brewing, environmental protection, port, light industry, electric power and other fields. With the development and application of spin-up forming steel plate warehouses in various fields, there is a strong demand for large-volume, ultra-thick (steel plate thickness greater than 5mm) spin-up forming steel plate warehouses. However, when the steel plate used in the spin-up forming steel warehouse has a width of 750mm and a thickness of more than 5mm, due to the increase in the strength of the steel and the decrease in elongation, the bending of the upper and lower edges of the steel plate during the spin-up forming manufacturing process will be difficult. And the diffic...

Problems solved by technology

However, when the steel plate used in the spin-up forming steel warehouse has a width of 750mm and a thickness of more than 5mm, due to the increase in the strength of the steel and the decrease in elongation, the bending of the upper and lower edges of the steel plate during the spin-up forming manufacturing process will be difficult. And the difficulty of seaming the edges of the adjacent steel plates after bending is greatly increased, so that the current manufacturing system of the rotary forming steel plate warehouse cannot meet the bending and joint quality of the steel plates with the above parameters
