Design principle of automatic fiber cutting machine

The large-diameter simplified curve cutting machine developed by the Taiwan-group automatic fiber cutting machine has simple structure, stable transmission, and can be used. It is especially suitable for the rotation and downward movement of the torch of the large-diameter cylindrical cutting torch. The two are synchronously coordinated, and the parts can be ignited and cut at any time. There is no transmission accumulation. The structure is simple, the operation is convenient and the operation is reliable Practical application proves that the machine can greatly improve the production efficiency, the cutting quality is stable and can be improved step by step. The welding torch can be used to replace the cutting torch, and it can also be used for the automatic welding of domestic power pipelines and cylindrical containers. Most units still use backward production methods such as manual lofting and manual flame cutting and polishing. The production quality is poor and the labor intensity is large. A few units use mechanical cylindrical table group automatic fiber cutting machine, but due to its problems, it cannot meet the high temperature of thick wall. , The strict requirements of high-pressure pipelines and containers urgently need to adopt and promote economical, portable, multi-functional, mechatronics cylindrical table group automatic optical fiber cutting machine. Wuhan University of Water Conservancy and Electric Power successfully developed a type of microcomputer numerical control cylindrical table group automatic Optical fiber cutting machine, and passed the provincial appraisal in the same year and month, and successfully developed a microcomputer group automatic optical fiber cutting machine cutting machine. Both cutting machines are economical, portable, multi-functional, and mechatronics. Patented products, they use oxygen cutting, which can cut low carbon steel and ordinary low alloy steel. If equipped with plasma cutting equipment, it can also cut stainless steel. The above two cutting machines have proved to be stable in operation, good in anti-interference performance, reliable in work, low in noise, and high in efficiency. , The cutting quality is good, the installation is flexible and convenient, especially on the cone surface of the large gas hood of Baosteel No. 3 blast furnace, a number of thick walls intersecting perpendicularly or obliquely to the cone surface generatrix are cut.

Taiwan group automatic fiber cutting machine large diameter group automatic fiber cutting machine hole, solves the key technical problems, the existence of special mechanical cylindrical group automatic fiber cutting machine The problem Xin Xian (discussed the mathematical model of the two-axis perpendicularly intersecting group automatic fiber cutting machine, the design principle and the processing range of the mechanical cylindrical group automatic fiber cutting machine, and the main problems of this cutting machine are discussed below. The design principle of the automatic optical fiber cutting machine is based on the approximate replacement of the guide rod displacement curve of the crank guide rod mechanism. The theoretical curve of the automatic optical fiber cutting machine of the two axis perpendicularly intersects the theoretical curve of the automatic optical fiber cutting machine. This design principle determines this cutting A single machine can only cut two-axis vertical intersection group automatic fiber cutting machine. It cannot cut two-axis oblique intersection, eccentric vertical cross, eccentric oblique cross-stage group automatic fiber cutting machine, and it cannot cut welded elbows. The machining range of the automatic optical fiber cutting machine with variable angle welding and beveling mechanical cylindrical table group automatic optical fiber cutting machine is affected by the radius of the intersecting cylindrical surface of the main pipe or the cylindrical container, and the supporting Wuhan University of Water Conservancy and Electric Power According to the limitation of the ratio of the radius of the pipe to the cylindrical surface, it is generally required that if the value is too small, the displacement of the cutting device along the axis of the branch pipe is required to increase during cutting, and even the larger displacement that the cutting device may achieve will cause the cutting The larger error of the actual displacement curve of the nozzle relative to the theoretical displacement curve is rapid, and the increase will cause the angle between the axis of the cutting nozzle and the normal of the surface to be cut to increase near the two lower points of the intersecting line hole, making the cutting flame When the skew occurs and affects the cutting quality, the cutting flame length between the cutting nozzle and the surface to be cut should be kept basically unchanged. When the cutting quality is affected by the automatic fiber cutting machine hole, the surface to be cut is not round, or the part to be cut is thermally deformed, Or when the cutting machine is installed with errors, the cutting flame length changes greatly. The above cutting machine cannot be automatically adjusted, and the operation is inconvenient. When cutting cylinders, especially the two axes with close cutting values Vertically intersecting cylinders or eccentrically intersecting cylinders with two axes.
