Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cutting device. 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 incision of a workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form an incision. It is widely used in the steel field for cutting because of its convenient operation, fast cutting speed and high precision. China has authorized a utility model patent (publication number: CN219648916U) to propose a plasma cutting device, in which a smoke extraction port is provided on the inner wall of the protective cover to limit the smoke inside the protective cover, and the smoke is extracted by a fan and discharged after being filtered and adsorbed by a filter tube, thereby preventing the smoke from polluting the working environment of the device.

[0003] However, the above device still has some shortcomings when in use: since the smoke generated during the cutting process is often accompanied by a high temperature, the smoke directly entering the stuffing bin will cause the temperature in the bin to rise significantly. The high temperature environment not only affects the filtering effect of the stuffing, but may also cause the material in the stuffing bin to age and deform, and even cause safety hazards such as fire. Secondly, the high-temperature smoke entering the fan can easily cause damage to the internal electrical components and mechanical parts, resulting in performance degradation, frequent failures, and even premature scrapping. Therefore, a cutting device is proposed to address the above situation. Summary of the invention

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the smoke generated is often accompanied by a high temperature. The smoke directly entering the filling bin will cause the temperature in the bin to rise significantly. The high temperature environment not only affects the filtering effect of the filler, but may also cause the material in the filling bin to age and deform, and even cause safety hazards such as fire. A cutting device is proposed.

[0013] Preferably, a box door is hinged on the box body, and a number of exhaust holes are provided on the box door.

[0014] The utility model has the following beneficial effects:

[0015] 1. By adopting a square tube with an S-shaped design and arranging a number of first heat sinks on the square tube, the utility model can effectively increase the flow path of the smoke in the square tube, thereby prolonging the contact time between the smoke and the first heat sinks, enabling the heat to be better dissipated through the first heat sinks, significantly improving the cooling efficiency, thus realizing the reduction of the temperature of the smoke entering the packing bin inside the box body, reducing the damage of high temperature to the packing bin and the filter material inside it, thereby prolonging the service life of the equipment. At the same time, reducing the smoke temperature also helps to reduce the damage to the fan.

[0016] 2. By obliquely arranging a number of second heat sinks on the first heat sinks penetrating into the interior of the square tube, after the smoke enters the interior of the square tube, the flow rate of the smoke can be reduced, making the smoke more evenly distributed in the square tube, further improving the uniformity and quality of cooling, and effectively preventing the problems of local overheating or insufficient cooling of the smoke.
