Frame processing technology in steel structure manufacturing process

In the manufacturing process of steel structure, to ensure the welding quality, technological welding, and assembly accuracy, the edge of steel plate must be planed or shovelled into a bevel, and at the same time, it must be planed or milling.

1. In the process of steel structure processing, the main part of the corner treatment is as follows. Flange plate and support surface of crane beam with technical requirements. There are welds specified in technical documents on the design drawings. There are strict requirements for dimensional accuracy of neck plate, baffle plate, web plate, with holes, etc.

2. Cutting edge technology:

1) Scraper: for steel structure parts that do not require high quality and workload, shovel edges can be used. The edge of the shovel can be divided into manual and mechanical two kinds. Hand shovel edge tools are hand hammer, hand shovel and so on.

2) Section: In steel structure manufacturing, edge planing machine is mainly used for edge planing of steel structure parts. There are two types of edge planing processing for steel components: straight edge and beveled edge. The width of the edge planing varies according to the thickness and cutting mode of the plate. The typical cutting width is 2-4 mm.

3) Milling: for the end of some parts, you can use milling (face machining) process to ensure the accuracy of the parts. Grinding. It is usually processed by face milling or milling.

4) Carbon arc cutting: carbon arc gouging, using carbon fiber. The arc has a temperature of about 6,000 degrees Celsius, enough to melt the metal and blow it away using a stream of compressed gas. Used to plane or cut metal.

When carbon arc air gouging is used for groove or root clearing, the oxide layer, hardened layer, top carbon or copper in the groove should be polished comprehensively. Because the carbon arc air gouging will produce a lot of smoke in the gouging, causing harm to human body, therefore, the construction site must have a good ventilation environment.
