Fully automatic fiber cutting machine overcomes many technical problems and innovates boldly
Taiwan group automatic optical fiber cutting machine has the following characteristics: ①The temperature of the nugget fluctuates up and down the average value, and the fluctuation frequency is much like that of welding. Therefore, when the welding current reaches the peak value, it is easy to cause the flying current due to the nugget rupture; In the first 1/2 cycle of the start of conduction, the temperature rise is the most splashy; secondly, at the beginning of the energization, because the temperature rises very quickly, it is easy to cause rapid rise, and then the rise is gentle. Figure 3b shows the surface spatter of the nugget at an early stage when welding with an inverter welding machine; when welding with an inverter welding machine, the over-average temperature changes due to the current rise. Compared with the case of AC, it is a sloping line that rises steadily, so the temperature rise rate is very stable and basically unchanged. (a) The temperature change curve during AC welding (b) The temperature change curve during inverter welding Circle 3 The change curve of the nugget zone during welding with 2 types of welders shows the circle 3 Welding process performance analysis Three-phase inverter resistance Welding machines are quite different from AC welding machines in terms of welding current waveform, heat generation characteristics, and nugget temperature change law. This is why the welding process performance of inverter welding machines is different from traditional AC welding machines. The author will analyze one by one below. (1) Inverter welding machine produces less spatter. For the AC welding machine, first of all, because the heating process is pulsating and discontinuous, the peak power is higher than the average power and can be controlled. Therefore, the heating process is very stable, and the temperature rises continuously and slowly, so it is not easy to appear This kind of spatter, if the welding parameters are controlled properly, the spatter can be completely avoided. (2) The inverter welding machine can extend the life of the electrode. Due to the large temperature fluctuation range during AC welding, the peak temperature on the contact surface between the electrode and the workpiece is relatively high, which will aggravate the burning loss of the electrode when welding aluminum alloy and galvanized sheet, thereby shortening the service life of the electrode; while the inverter welding machine Since the temperature rises continuously and slowly during welding, the electrode is not easily damaged.
Taiwan group automatic fiber cutting machine inverter welding machine should not use too short time and large current. This is because the heating process of the inverter welding machine is gentle, when the energization time is too short, the heat accumulation is insufficient, and it is difficult to weld equipment and materials · Welding Technology Vol. 35 No. 2 April 2006. At present, most Chinese enterprises are fully automatic in Taiwan When the optical fiber cutting machine interface, almost all adopt the backward production method of manual scribing, cutting, and polishing of the template, which results in low production efficiency and poor product quality. The existing domestic equipment has poor technical performance and the imported equipment is expensive, which severely restricts the improvement and development of the steel pipe cutting process. Therefore, it is urgent to adopt the Taiwan group automatic fiber cutting machine. In addition, my country's intersecting interfaces for steel pipe welded bridges, drilling platforms and export ships. It has been stipulated that a group of automatic fiber cutting machines must be used. In order to meet the market demand and improve the quality of the automatic fiber cutting machine for the tube station group, after consulting a large number of relevant domestic and foreign materials, the firm used scientific and reasonable analysis methods and testing methods to overcome many technical problems and boldly innovate. Successfully completed the design, installation and commissioning of the Taiwan-group automatic fiber cutting machine, and made the equipment's multiple technical performance indicators have reached the international leading level.
