With the development of offshore oil exploration to the deep sea, the full-automatic fiber cutting manufacturers of Taiwan and the whole Taiwan group, the scale of jackets and blocks used for offshore oil and gas exploitation tends to be large, and the corresponding pipe diameters, walls The thickness also increases. In the process of processing, the automatic fiber cutting of the tube end group is various, and the cutting difficulty and precision are getting higher and higher. This requires the automatic fiber cutting of the entire group of the group to follow. Updates and improvements to meet the development needs of steel structure construction. This article introduces two typical CNC table group automatic optical fiber cutting and cutting machines, combining their applications in jacket and block construction and existing problems, and making corresponding improvements to better improve production efficiency and quality. Keywords: Taiwan-group automatic optical fiber cutting and cutting machine; offshore oil; steel structure; Taiwan-group automatic optical fiber cutting is the main structural form that connects the tube to the tube and the tube to the plate in the offshore oil engineering steel structure, and its cutting quality is good or bad It has a significant effect on the welding strength of jackets and blocks, so the accuracy of the automatic fiber cutting and cutting of the group must be ensured during processing, so as to avoid quality problems during welding. The traditional methods of automatic optical fiber cutting and cutting are all done by hand. The specific construction process is: lofting the automatic optical fiber cutting trajectory of the Taiwan group-making a template-marking the workpiece-manual cutting-polishing the sample, such a cumbersome processing method , Not only the production efficiency is low, the labor intensity is high, but the product quality is poor, and it is impossible to guarantee the uniform weld seam after the workpiece is intersected.
In order to solve the above problems of high consumption and low output, the full-automatic fiber cutting manufacturers of Taiwan and the whole group need to use CNC automatic fiber cutting and cutting machines to ultimately increase the output and The quality must also be improved as necessary with the development of offshore oil steel structures. At present, the equipment used for the automatic fiber cutting and cutting of the group is mainly the Jinfeng XMG series cutting machine and the rotatable tube end automatic cutting machine. This article introduces the two devices from the four aspects of structure, capability, advantages and disadvantages, in order to efficiently configure the equipment resources and improve the efficiency of production. The characteristics of the two CNC table group automatic fiber cutting and cutting machines Jinfeng XMG The Jinfeng XMG series CNC cutting machine is mainly used for cutting various low-carbon steel, stainless steel and other pipe materials, with high efficiency, high precision and high level of automation. The structure consists of a mobile frame, a power rotating head and a cutting head. By moving the frame, the running rail and the carriage rail are kept in balance, thereby increasing the cutting accuracy of the machine. The power rotating head drives the workpiece up and down, forwards and backwards through the chuck, and the cutting head is used to cut pipes. It can deflect in the axial and radial directions. Through the system control the linkage of the above motion axes, the automatic fiber cutting of the steel pipe group group is finally realized. Cutting ability, advantages and disadvantages. Jinfeng cutting machine not only has high production efficiency and low labor intensity, but also has high cutting accuracy. After cutting, the rod has accurate mouth shape and high quality, which reduces the grinding and repair work of the automatic fiber cutting groove of the group. . Through the numerical control system of the console, the cutting torch mounted on the machine performs plane geometric motion according to the input cutting parameters, and only the height of the cutting torch and the size of the flame and the walking speed of the machine need to be adjusted to realize the continuous cutting of the steel pipe. Steel pipes with a pipe diameter greater than Φ406mm are generally coiled pipes, and longitudinal welds are bound to exist. The steel pipe is always on the roller during the cutting process of the Jinfeng cutting machine. The roller will drive the steel pipe to rotate during the radial rotation process, which will inevitably cause the longitudinal seam to contact the roller at a higher point, which will naturally raise the pipe. As a result, gaps will appear during the fully automatic fiber cutting of the cutting table group, and this type of problem will also occur when the longitudinal weld is rotated to the other end and the other side. Rotatable tube end cutting machine This equipment system consists of a group of automatic fiber cutting and cutting machines, 3 electric mobile tube support positioning cars, 2 mobile saving cars, and two pairs of wide and narrow rails.
