Description

Technical Field

[0001] The utility model relates to the technical field of cutting workbenches, in particular to a plasma cutting workbench. Background Art

[0002] Plasma arc cutting is a processing method that uses the heat of a high-temperature plasma arc to partially melt and evaporate the metal at the incision of the workpiece, and uses the momentum of high-speed plasma to expel the molten metal to form an incision. However, a large amount of toxic and harmful gases will be generated during plasma cutting. These gases will have an impact on health when inhaled by people. In addition, the workpiece needs to be placed on the grid plate during cutting, so the grid plate is very easy to be damaged. However, the existing grid plates are basically connected by welding, which makes the replacement of the grid plates very inconvenient.

[0003] For example, a plasma cutting dust removal and slag collecting workbench disclosed in a Chinese utility model patent with a publication number of CN219805517U and an authorization announcement date of October 10, 2023 belongs to the field of plasma cutting dust removal technology, and includes a bracket, the bracket includes a table top and a plurality of supporting legs, an opening penetrating the upper and lower sides of the table top is provided, a plurality of grilles are provided in parallel in the opening, a slag collecting bucket is provided under the grille, the slag collecting bucket is in an inverted cone shape with a truncated tip and a first slag outlet is provided at the bottom, an exhaust pipe is provided below the first slag outlet, a second slag outlet is provided at the upper position of the right wall of the exhaust pipe, and a filter plate is installed in the exhaust pipe,

[0004] However, in actual use, the above patent allows metal slag and metal particles to be cleaned out very conveniently through the design of structures such as the table, grille, and slag bucket. However, since the exhaust port is set below the slag outlet in the above patent, this will not only affect the exhaust effect, but also make it difficult for the metal slag and metal particles to slide out from the second slag outlet when they fall onto the filter plate above the exhaust port, and will also block the filter plate, thereby affecting the exhaust effect. In addition, since the grille itself is very easy to be cut and damaged during the cutting process, the above grille is fixedly connected to the table, which makes it very troublesome to replace the grille. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model connects the input end of the exhaust fan with the four smoke exhaust ports at one end of the connecting plate through the design of a five-way pipe, so that the smoke generated during the cutting process can be smoothly sucked away by the exhaust fan, thereby avoiding the smoke from affecting the health of the staff. The design of the filter plate can prevent the metal slag generated during cutting from entering the exhaust fan and affecting the operation of the exhaust fan. The filter plate is arranged on the connecting plate, so it is difficult for the metal slag to fall directly onto the filter plate during the falling process, so the filter plate is not easily blocked, thereby reducing the number of times the filter plate is replaced. The design of the guide plate can guide the metal slag to the slag outlet for discharge, which is convenient for people to clean. In addition, the design of the L-shaped plate allows the grille plate to be directly overlapped in the support frame, so it is very easy to replace the grille plate when it is damaged.
