For structural steel suppliers - those who supply high-rise buildings, industrial facilities, power plants, conference centers for cutting, welding, forming and manufacturing joists, trusses and beams - the definition of automation in the past decade has been CNC beam drilling lines. A beam rig line is a mechanical system that uses a conveyor to move a steel beam or "beam" into place and then drills multiple locations along the steel piece - sometimes bolt holes - according to the instructions provided in the engineering drawings. What is the final product.
The automatic beam drilling line is a much more productive factor than the traditional method of digitally measuring a bare beam on a paper-based drawing to mark it and then manually drilling it [usually using a heavy-duty drilling machine]. Of course, this is a full manual process.
Modern beam drilling lines can digest digital drawing files, find the location where holes are to be placed, use the positioner, sensor and drill bit to "probe" the beam itself, then use superhard carbide to drill through the steel drill bit at an impressive speed and Coolant. The bolt holes are completed in a short period of time. Most of the manpower is to take the steel workpieces up and down and download the drawing files to the machine's control system.
This is a huge advantage compared to the "old fashioned" approach, but there is a problem and it is a big problem. There are also many manufacturing operations that must be performed on steel beams. Cutting various shapes [such as tops, notches, bevels] into beams, trimming the ends of the parts to a specified length, and "burning" different characters and symbols into the part is often required for many steels. Additional operating beam. None of these operations can be performed through the beam drilling line.
In summary, although the beam drilling line increases the productivity of the drill bolt hole, it does not automatically perform any other tasks.
A completely different manufacturing method comes from the sheet metal manufacturing industry, which demonstrates that drilling operations are as fast and fair as beam drilling lines, but bring the same level of automation to all other cutting and engraving tasks performed on steel beams. The new method uses high-definition plasma cutting to thermally cut or scribe light beams.
This technique is similar to a beam drilling line, the structural part of which is transferred to the plasma torch body, the digital drawing file is loaded into the PC-based control system of the plasma machine, and the torch tip contacts the workpiece to figure out [and remember] it The exact location in 3D space and all its various functions. Then the plasma torch starts working, not only making bolt holes, but also making notches, notches, and upper and lower cuts. . . A complete list of features for structural steel supplier customer needs.
The automatic plasma cutter can generate all of these required functions, from one side of the beam to the other. Once completed, all required operations are completed - there is no need to transfer the completed beam to the downstream process. To some extent, the new plasma technology is a "full service" suite of structural steel suppliers.
Different versions of these plasma machines are coming soon, with various capacities and prices. But one thing seems to be affirmative. . . The best day for beam drilling technology is in the rearview mirror.
