Description

Steel structure chamfering device

Technical Field

The utility model belongs to the technical field of steel structure beveling, and particularly relates to a steel structure beveling device which is particularly suitable for H-shaped steel, channel steel and the like.

Background

In the processing and manufacturing of steel structures, such as H-shaped steel, channel steel plates and the like, chamfering is an important process, chamfering tools are also five-flower eight doors, milling type automatic walking flat iron edge machines, robot flame chamfering machines, automatic walking chamfering machines, semi-automatic flame cutting machines and the like are adopted, but the equipment is large in size and weight, and suitable for cutting long and concentrated grooves. However, for short and position-dispersed grooves, the equipment is too heavy to be conveniently used, and the equipment can only be used in workshops, cannot be carried and cannot be used on sites;

the manual flame cutting is often used in the situation, the bevel cut by the manual flame cutting is influenced by the technology of workers, the surface of the bevel is very uneven after the cutting is finished, a large number of edges and saw teeth exist, and the bevel angle is difficult to control. The groove needs to be manually polished, the edges and the saw teeth of the surface of the groove are flattened, a large amount of labor is consumed, and the processing quality of the groove is poor.

At present, some small-sized chamfering devices, such as an H-shaped steel chamfering device of CN217393993U , are also available, but the structure is very complex, the volume is large, the size is heavy, and the problems are also existed.
