The invention relates to a three-cutting torch curve groove cutting device. The cutting device comprises a connection frame, a servo rotary motor and a rotary main shaft which is positioned above the connection frame, wherein a rack bar is arranged on the connection frame; a central cutting torch connection frame is fixedly arranged on the rack bar; two sides of the central cutting torch connection frame are provided with left and right moving bodies; the left moving body is connected with a left hand wheel which is meshed with the rack bar; the right moving body is connected with a right hand wheel which is meshed with the rack bar; a left cutting torch holder is arranged on the left moving body; a right cutting torch holder is arranged on the right moving body; an output shaft of the servo rotary motor is connected with an input shaft of a reduction gearbox; output gears are arranged on the output shaft of the reduction gearbox; rotary gears are arranged on the rotary main shaft; the rotary gears are meshed with the output gears; and the lower end of the rotary main shaft is fixedly connected with the connection frame. The whole cutting device has a compact structure and is easy and convenient to operate. When a cutting program of a corresponding straight line or curve is input, the device can automatically complete the whole cutting working according to the requirements of a groove of the straight line or the curve.
Description
(1) Technical field [0001] The invention relates to a three-torch curved groove cutting device. (2) Background technology [0002] With the continuous improvement of welding technology, the cutting amount of curved grooves of plates is increasing. For example, in the processing of wind power towers and hydraulic conduits, it is necessary to cut a large number of curved plates with various forms of grooves around them. The current processing method The outer contour of the curve is processed by a CNC cutting machine, and then different forms of beveling are performed on the periphery of the workpiece by manual or semi-automatic trolleys. This not only has low production efficiency and high labor intensity, but also the cutting accuracy and surface quality of the product cannot meet the requirements of the subsequent process. Process requirements for automatic welding. (3) Contents of the invention [0003] In order to overcome the deficiency that the existing cutting machi...
