Device for cutting steel intermediate bend intersecting line

Abstract

The invention relates to a device for cutting a steel intermediate bend intersecting line. A cutting torch longitudinal driving mechanism drives a cutting torch to move in the length direction of a bend, a rotary slider arranged on a circular guide rail slides along the circular guide rail, the cutting torch connected with the rotary slider is dragged to enable the cutting torch to rotate in the axis direction of the bend, and a cutting torch vertical driving mechanism drives the cutting torch to move in the radius direction of the bend. The cutting torch longitudinal rotary mechanism drags the cutting torch to swing around the axis direction of a parallel bend, and the motion of the cutting torch in the bend axis direction, the rotating motion of the cutting torch in the bend axis direction, the motion of the cutting torch in the bend radius direction, the swinging of the cutting torch in the parallel bend axis direction and the swinging of the cutting torch in the direction perpendicular to the bend axis direction are combined to form a combined motion of the cutting torch cutting the bend and simultaneously cutting a welding groove. The device for cutting the steel intermediate bend intersecting line can cut the intersecting line and the welding groove on the bend.

Description

technical field [0001] The invention relates to a device for cutting medium-sized steel pipes, in particular to a device capable of cutting along intersecting line tracks on medium-sized bent pipes of steel structures, so as to directly cut intersecting lines and welding grooves on the bent pipes. Background technique [0002] At present, a large number of bent pipes are used as structural pipes in steel structure engineering. When connecting steel structure elbows, it is necessary to cut intersecting lines at the joints on the elbows, and then weld the intersecting elbows together. The existing technology for cutting pipe intersecting lines is mainly aimed at pipes whose axis is straight, and the corresponding pipe clamping devices are relatively mature. There are clamping devices for clamping round pipes and square pipes whose axes are straight at home and abroad. At present, steel structure enterprises generally use a modified method to cut the intersecting line on the e...
