To sum up, the flexible cutting track equipment 1 at variable inclination of this application, what flexible steel sheet 3 adopted in this equipment is the flexible sheet material of carbon steel, what adopt promptly is the Q235B steel sheet, and the application its flexibility can closely laminate with different volumetric spherical shell inner curved surfaces to with two butt joint parallels in turn on adsorbing in the parallel distance cutting auxiliary line of aluminum alloy track 2 of spherical shell inner curved surface, collocation magnetic wheel flame cutting machine 28 just can accomplish utmost point sideboard side bend circumferential weld groove cutting. The equipment can meet the requirement of accurate cutting of the polar band plate side-bending circular seam groove of the spherical shell with different volumes, can effectively reduce occupational disease injury of operators, and improves the cutting quality and efficiency of the spherical shell plate in the pressure container. The equipment has an inclination angle adjusting function, and the technical problem that the adsorption magnetic wheel flame cutting machine 28 accurately cuts the spherical shell polar plate side-bending circular seam grooves with different volumes can be effectively solved by adjusting the installation angle between the triangular top plate 11 and the inclination angle adjusting plate 19. In addition, the sucking disc 12 in the device can be tightly attached to the inner curved surface of the spherical shell through the magnetic steel sheet on the sucking disc, so that the overall displacement of the magnetic wheel flame cutting machine 28 due to the influence of gravity in the cutting process is avoided, and the cutting quality can be effectively ensured.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
