[0002] Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially melt and evaporate the metal at the workpiece incision, and uses the momentum of high-speed plasma to expel the molten metal to form an incision. When a plasma cutting machine is cutting a workpiece, a cutting frame is required to support the workpiece.

[0003] The search publication number is CN219131090U, which discloses a positioning mobile processing table for a plasma cutting machine. By setting a limit cylinder, the push plate pushes the workpiece to the side, so that the workpiece is pushed to the right side of the support frame for limiting. Then the clamping cylinder is started, so that the clamping block pushes the workpiece to the lower side of the support frame. Through the action of the ball, the workpiece is fixed at one end of the workbench, and the workpiece is quickly positioned.

[0004] In the process of realizing the present utility model, the inventors found that there are at least the following problems in the prior art that have not been solved. In the above case, the staff needs to manually place the workpiece on the cutting frame for cutting. After the workpiece is cut, the staff needs to wait for the workpiece to cool down before removing the workpiece. During this process, the plasma cutting machine cannot work normally, affecting work efficiency.

[0005] Therefore, we propose a portable cutting frame for an automated plasma cutting machine, which can solve the above problems. Utility Model Content
