Continuous automatic manufacturing process for T-shaped steel purlin supporting sheet

Abstract

The invention relates to the technical field of steel structure manufacturing, in particular to a continuous automatic manufacturing process for a T-shaped steel purlin supporting sheet. The process comprises the following process steps of 1, shearing and straightening a rolled sheet through a longitudinal shearing and leveling unit according to a required size to obtain two straight strip steel sheets which serving as a connecting sheet and a supporting sheet correspondingly; 2, welding the two strip steel sheets serving as the connecting sheet and the supporting sheet correspondingly into T-shaped steel through an automatic grouping and continuous welding unit; 3, straightening the T-shaped steel through a T-shaped steel straightening unit; 4, carrying out positioning and side-by-side double-position punching treatment on the straightened T-shaped steel through a multi-station numerical control hydraulic unit / numerical control punching unit; and 5, cutting the T-shaped steel according to the required size of the purlin supporting sheet and simultaneously removing corners of the supporting sheet so as to form the purlin supporting sheet with the right trapezoid-shaped supporting sheet. The process method has the advantages of simple manufacturing process, high production efficiency, consistent size and accurate punching positioning effect.

Description

technical field [0001] The invention relates to the field of steel structure manufacturing, in particular to a continuous automatic manufacturing process for T-shaped steel purlin supporting plates. Background technique [0002] Purlin supporting boards are mainly used in industries such as steel structure workshops and roof buildings, solar photovoltaic power station supports, etc. The use of purlin support plates can make the installation and construction of steel structures more convenient, fast, accurate and firm, reducing on-site welding links, and facilitating the demolition and recycling of buildings. [0003] The existing manufacturing process of the purlin support plate generally adopts coiled steel plates to be flattened → cut into small pieces of different shapes by a horizontal shear machine or a vertical and horizontal combination unit → positioned by the corner of the connecting plate, turned up and down on the front and back sides and punched separately → plat...

AI Technical Summary

Problems solved by technology

There are also cutting equipment such as plasma or flame for cutting. Although the edge and hole distance are accurate in this way, there are problems such as smoke pollution during cutting, large material loss, low efficiency, and deformation during welding.

There are also methods in which steel plates are bent or cold-formed to form V-shaped, U-shaped or groove-shaped support structures. Although the welding process is reduced, the area of ​​the steel plate is significantly increased, resulting in increased costs and due to factors such as wind load and snow load. It is easy to cause deformation of the purlin support plate

Due to the inaccurate positioning of the punching holes in some purlin support plates, the installation holes are changed to waist-shaped long holes, which is convenient for installation, but the connection accuracy of the roof purlins becomes poor, and they are locked only by the friction of the bolts, forming a certain amount of activity, which affects the construction. stability, leaving certain security risks

To sum up, the current manufacturing process or products of purlin support boards have relatively large limitations, and there are certain deficiencies in production efficiency, product quality, production methods, installation and use, etc. Construction standard high efficiency, low cost, precision, standardization, continuous production of high quality purlin support board technology
