Flame cutting machine(CNC/GDZ—4000),Gantry type flame cutting machine
CNC cutting machine is a multifunctional thermal auto-cutting device combined microcomputer controlling, precise machinery and oxygen-acetylene gas cutting. Its CNC cutting torch can cut plates in arbitrary shape. Several cutting torches which are used to cut strips are fixed on the other side. As the steel plate can be heated and cooled at the same time, the side-curve will eliminate once for all. This kind of machine is composed of a gantry frame, main and secondary longitudinal guide rail, transverse torch (flame), longitudinal strip torch (multi-head) and CNC system. Both driving end and cross beams adopt box-beam welding structure whose stress has been relieved, with compact structure and artistic appearance. The driving of the main longitudinal end beam adopts Japan Panasonic AC servo driving system and driving epicyclical and Japan SHIMPO or Panasonic decelerator, through rack-and-pinion gearing. At the side of driving end beam fixes horizontal directive wheels which can be used to fasten by adjusting the eccentric shaft, therefore, the stability and accuracy during the whole moving can be assured. The longitudinal guide ways firmed by pressure plate backing board and connecting sleeve, all made by high intensity track, all the contact surface of track have precision machining and accurate grinding racks are installed outside the guide way. This installation method can guarantee the straightness and parallelism of guide way. The transverse cutting torch fixed on the transverse tool carriage. Its moving also realized by AC servo electric machine made in Japan Panasonic to drive the epicyclical decelerator, then use the way of rack-and-pinion driving. The illustration of the transverse beam: it is made of box-beam and its wall is thin, it is assembled by sheets and the stress of the whole workpiece has been relieved. It featured by light weight, strong toughness, little deformation and artistic appearance.There has a high accuracy guide rail and pinion at the backward of the transverse beam. The transverse driving device uses a big speed radio reducer. It’ll drive the whole machine transversely when the export axles rack match with the pinion. The transverse driven device moves synchronously with the driving device through link between the strip and the driving device. The gantry frame Illustration: the main gantry is assembled by sheets and the stress of the whole workpiece has been relieved. Both ends have horizontal wheel which can adjust the two sides that are clamped by longitudinal guide rail. It’ll play the guiding role when the whole machine moves back-and-forth, and its structure is compact and stable. The longitudinal driving device uses a big speed radio reducer, with a tooth space take-up mechanism featured of precise guiding. It’ll drive the whole machine longitudinally when the export axles rack match with the pinion of the longitudinal guide rail. Longitudinal gauge: it is mainly made up of gauge and rack. The gauge made of 24kg steel which has been processed is installed at the beam along which the machine will move longitudinally. Gas path Illustration: longitudinal and transverse cable and gas pipe all adopt the engineering plastics chain produced in Korean Koduct.
