Railess automatic guiding flame cutter

Abstract

The invention provides a railess automatic guiding flame cutter. The cutter is formed by a frame, two travelling wheels, a driven wheel and a cutting torch, wherein a regulating rod is arranged in the frame; the cutting torch is arranged at one end of the regulating rod and positioned outside the frame; the travelling wheels are arranged at the front part of the bottom of the frame; the driven wheel is arranged at the rear part of the bottom of the frame; a regulating lead screw is arranged in the frame; one end of the regulating lead screw extends out of the frame to be connected with a backup arm; the backup arm and the cutting torch are positioned at the same side of the frame; and the front end of the backup arm is provided with a backup wheel. When a beveling is performed on the steel plate with an arc-shaped edge, the backup arm extends inside the lateral side of the plate, and the backup wheel is closely attached to the lateral side of the plate. When the frame moves forward, the driven wheel faces to the internal side of the steel plate, the travelling direction of the driven wheel is controlled by the machine-shaping appearance of the plate in the previous process and the backup arm, and the cutting torch is used for cutting the beveling for the plate. The distance between the backup wheel and the frame can be changed by adjusting the screw rod so as to adapt to the curve radius of the steel plate.

Description

Technical field: [0001] The invention relates to the mechanical field, in particular to a steel plate cutting device, in particular to a trackless automatic guiding flame cutting machine. Background technique: [0002] Beveling of steel plates is often carried out in the production of steel structures, especially for welding materials with high welding strength, it is necessary to bevel the steel plates. In the prior art, a semi-automatic trackless automatic guiding flame cutting machine is used for beveling processing. The semi-automatic trackless automatic guided flame cutting machine is placed on a custom-made track, and the crawling mechanism of the semi-automatic trackless automatic guided flame cutting machine is used to move and cut. If the steel plate to be processed is longer, the guide rail should be extended. The direction of the semi-automatic trackless automatic guide flame cutting machine is controlled by the line type of the guide rail. However, if the posit...

Problems solved by technology

However, if the position of the bevel to be processed is an arc edge, it must be equipped with a corresponding arc guide rail to perform bevel cutting. If there are processing requirements of various radians, corresponding various The radian working guide rail is used to control the walking of the cutting machine, so it is labor-intensive and time-consuming, and the production cost is high
