This method takes a long time to cut, has high noise and low work efficiency; the other method It is to first draw a circle on the steel plate to be processed according to the required diameter, and then cut it with a plasma cutting machine. Although this method improves the cutting speed, it cannot guarantee the accuracy of the cut circular steel plate.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the above-mentioned technologies, and provide a circular steel plate cutting machine, which can improve work efficiency and ensure the precision of cutting circular steel plates.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a special cutting machine for circular steel plates, characterized in that it includes a frame, a motor reducer, a step shaft, a rotating disc and a plasma cutting machine, and the rotating disc and the ladder One end of the shaft is keyed, and the stepped shaft is supported by a bearing seat fixed on the frame through a bearing. The other end of the stepped shaft is keyed with a worm wheel, and the worm wheel meshes with the worm, and the worm is fixed on the frame through the bearing. The lower bearing seat is supported, the other end of the worm is keyed with a bevel gear, and the bevel gear meshes with the active bevel gear keyed on the output shaft of the motor reducer, and the cutting nozzle of the plasma cutting machine passes through the adjustable bracket Fixed on the top of the rotating disk.

A working disk with a diameter smaller than that of the rotating disk is fixed coaxially on the upper part of the rotating disk, and a pressing block is arranged on the upper part of the working disk.

The adjustable bracket is composed of a cross bar and a vertical rod, the vertical rod is fixed on the frame, the vertical rod is vertically fixed to the cross bar through fastening bolts, and the horizontal bar is provided with a scale and a cutting mouth tight fixed device.

The cutting nozzle fastening device is composed of a sliding sleeve and a fastening bolt, the sliding sleeve is slidably connected with the cross bar, and the cutting nozzle is fixed on the sliding sleeve through the fastening bolt and the pressure piece

Beneficial effects: the utility model has a simple structure and is practical. The steel plate to be processed is placed on the working disk, and the position of the cutting nozzle on the cross bar is adjusted according to the size to be cut. The motor reducer drives the rotating disk and the working disk to rotate, and the plasma cutting The machine automatically cuts steel plates, and can cut out circular steel plates of different sizes, greatly improving work efficiency and ensuring cutting accuracy.
