Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine capable of preventing a workpiece from deflecting. Background Art

[0002] A cutting machine is a common workpiece processing equipment, mostly used for cutting and shaping plates to obtain the desired shape and size. When processing metal plates, flame cutting is generally used, using gas and oxygen or gasoline and oxygen to cut metal materials. It is low-cost and low-pollution, and can quickly cut thick metal plates.

[0003] Most of the common cutting machines of this type on the market are similar in structure. They use servo mechanisms, hydraulic cylinders and other mechanisms to drive the cutting nozzle to move horizontally and vertically, and quickly cut the plates placed on the cutting table. There are some functional deficiencies in actual use and there is room for improvement. For example, during the cutting process, the high-speed gushing flame itself has a certain impact force. When cutting plates of light thickness, the plates are affected by the flame and gas blowing, and are prone to shaking and deflection, which affects the cutting accuracy. The machine does not have the function of fixing the workpiece to prevent deflection. Secondly, the metal chips generated during the cutting process are blown by the airflow and will fall directly into the supporting platform or the supporting slot, and will be blocked by the top supporting rod, which will make it difficult to clean them later. The machine does not have the function of facilitating the cleaning of chips. In addition, the height of the supporting platform or the supporting slot that supports the workpiece is fixed. When processing plates of different thicknesses, the fixed working height will affect the cutting efficiency. The machine does not have the function of facilitating the adjustment of the supporting height.
