Description

Technical Field

[0001] The utility model relates to the technical field of plasma cutting machines, and more specifically to a plate loading and unloading device for a plasma cutting machine. Background Art

[0002] Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially or partially melt the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to expel the molten metal to form an incision. Plasma cutting machines can cut various metals that are difficult to cut with oxygen cutting when used with different working gases, especially for non-ferrous metals. When using a plasma cutting machine to cut plates, manpower is often required to move the plates for loading and unloading.

The loading and unloading mechanism has a simple structure, is easy to use, has good stability, and high reliability, and realizes the loading and unloading of plates of different lengths (larger plates), thereby improving work efficiency.

For this reason, we propose a plate loading and unloading device for a plasma cutting machine. Utility Model Content

[0037] Working principle: when in use, first use the conveyor table 1 to move the plate to be cut to the bottom of the U-shaped frame 3, start the vacuum pump 18 to make the blowing hood 20 blow air, and use the wind force to clean the dust on the plate. In addition, the vacuum pump 18 sucks air from the inner cavity of the dust storage box 15 when blowing air. At this time, the suction pipe 21 and the suction hood 22 generate suction force, and the dust blown by the wind is sucked into the inner cavity of the dust storage box 15 by the suction, and the dust is trapped in the inner cavity of the dust storage box 15 by the filter screen 16.

At this time, the cylinder 24 is started to drive the suction cup 7 and the plate to move upward. During the upward movement, the second motor 13 is started to drive the rotating frame 10 and the L-shaped support plate 12 to rotate, so that the bottom end of the L-shaped support plate 12 moves to the bottom of the plate, and the plate is supported by the L-shaped support plate 12.
