Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a gas cutting device for avoiding scribing. Background Technique

[0002] In the processing and manufacturing of steel structures, the scribing accuracy has an important influence on the processing quality of steel structures. For the convenience of blanking, the web is usually rectangular during blanking, and the four corners at the ends are all right angles. However, in many component details, the ends of the webs are not right angles. Additionally, considering the welding shrinkage, a certain margin is usually left. After welding is completed, the excess part at the end needs to be cut off.

[0003] For cutting, scribing needs to be done first, and then cutting is carried out along the scribed line. The current scribing method: find the reference point and use a square to draw the lines on each surface. This work is cumbersome, and error accumulation is likely to occur during the line-drawing process, which not only affects work efficiency but also is not conducive to the control of processing accuracy. To overcome this drawback, a gas cutting device without scribing is specially developed to solve the deficiencies existing in the traditional scribing of the ends of steel structures. Content of the Utility Model

The device body includes a bottom fixing seat, a universal joint, a laser lamp, and a fixing fixture for fixing the laser lamp. The steel section to be cut includes a web and flange plates on both sides of the web. The laser lamp is connected to one end of the universal joint through the fixing fixture, and the other end of the universal joint is connected to the bottom fixing seat.

The laser lamp is located inside the limiting clamping plates, and the bottom of the limiting sliding groove on it abuts against the top of the limiting blocks.

[0009] As a preferred scheme of the utility model, the bottom fixing seat includes a bottom plate and a magnet located at the bottom of the bottom plate. The bottom fixing seat is connected to the web of the steel section to be cut.

[0010] As a preferred solution of the present utility model, it further includes an angle gauge for determining the reference points of the flange plates on both sides of the steel section to be cut. The reference points of the flange plates on both sides are determined by the angle gauge, and the bottom of the bottom fixing seat is connected to the upper surface of the web at the end of the steel section.

[0011] As a preferred solution of the present utility model, when adjusting, the beam of the laser lamp passes through the two reference points.
