The three side punching of channel steel is especially suitable for the three side drilling processing of H-beam and channel steel in steel structure, with high precision, high efficiency and simple and convenient operation. Therefore, channel steel three side punching is widely used in steel structure industries such as construction, bridge, power station boiler, stereo garage, offshore oil well platform, tower and mast. So what are the characteristics of channel steel three side punching? Here is a detailed introduction. < br style = "list style type: none;" / > features of channel steel three side punching: < br style = "list style type: none;" / > 1. The channel steel three side punching is mainly composed of bed, CNC sliding table, automatic stroke drilling power head, clamping mechanism, detection device, cooling system, scrap iron box, safety net and other main parts. < br style = "list style type: none;" / > 2. The lathe bed is a frame structure welded by high-quality steel. Through finite element analysis and calculation, the square steel tube is strengthened at the place where the stress is greater, and the heat aging treatment is carried out after welding. All these improve the static and dynamic performance of the bed and ensure the accuracy of the whole machine tool. There are three CNC sliding platforms, which are fixed side CNC sliding table, mobile side CNC sliding table and intermediate unit CNC sliding table. The three sliding platforms have the same structure and are composed of slide board, sliding table and servo drive system. There are six CNC axes on the three slides, and each slide has two CNC axes. Each CNC axis is guided by precise linear rolling guide rail and driven by AC servo motor and ball screw. As a result, each slide can move in two directions, either perpendicular to the workpiece feeding direction or along the workpiece feeding direction. After one feeding, all holes in one hole group (within 520mm) on H-beam can be processed in the same station, which ensures that the holes not on the same section of the workpiece can also be processed at the same time, which greatly improves the positioning accuracy and efficiency of the holes in the hole group. The three automatic stroke drilling power heads of channel steel three side punching are respectively installed on three CNC slide boards for horizontal and vertical drilling processing. The three drilling power heads can work independently or simultaneously. The automatic stroke drilling power head used in this machine can automatically switch from fast forward to work forward to fast backward without manual setting of drill length and workpiece thickness. The hydraulic clamping mechanism is used to clamp and fix the workpiece from horizontal direction and vertical direction respectively. < br style = "list style type: none;" / > 6. The channel steel three side punch is equipped with workpiece width detection and web height detection device, which can automatically compensate the processing error caused by irregular workpiece contour and improve the processing accuracy. < br style = "list style type: none;" / > 7. The channel steel three side punch is equipped with an air mist cooling system, which has the advantages of less coolant consumption, lower cost and less wear of drill bit. < br style = "list style type: none;" / > 8. The channel steel three side punch is equipped with iron chip box, and the chip can be automatically discharged into the box and transported conveniently. In order to ensure the safety of operators and the surrounding environment, safety nets are installed around the three side punching of channel steel. The electrical control system of channel steel three side punch is composed of PLC, motion control module, input / output module and high-speed counting module. It is composed of upper computer, AC servo drive system and frequency conversion speed regulation system. The system is equipped with 7 CNC servo motor shafts.
