Description

Technical Field

[0001] The utility model relates to the field of saw blade processing devices, in particular to a tool for removing slag in plasma cutting. Background Art

[0002] Saw blade plasma cutting refers to a process of cutting metal materials using a plasma cutting machine with a special saw blade (such as a carbide saw blade or a high-speed steel saw blade). This process combines the high efficiency and stability of saw blade cutting with the high temperature heat source advantage of plasma cutting. It is suitable for cutting thick metal plates, profiles or special-shaped workpieces, especially in situations where fast cutting and good cutting surface quality are required.

[0003] Slag generation is an inevitable phenomenon in the plasma cutting process. When the hot plasma arc cuts metal, the melted metal part will form molten residue during the cooling process, that is, slag. These slags will adhere to the cutting edge and the cutting machine. The presence of slag not only affects the quality of the cutting surface (such as roughness and precision), but may also cause difficulties in subsequent welding, painting and other processes, and affect the final performance of the workpiece. At present, the main way to deal with slag is to manually use tools (such as scrapers and brushes) to manually remove the slag on the machine tool. This method is labor-intensive, inefficient, and there is a safety risk of operators being exposed to high-temperature slag. Utility Model Content

DETAILED DESCRIPTION

[0021] like Figure 1 and Figure 4 As shown, a slag removal tool for plasma cutting includes a bottom frame 1 and a slag removal plate 4. The slag removal plate 4 is arranged in the bottom frame 1. The upper end surface of the bottom frame 1 is movably connected with a transmission rod 2. The transmission rod 2 can rotate freely around its own axis. The lower end of the transmission rod 2 is fixedly connected with the slag removal plate 4. The pry bar 3 is vertically connected with the middle part of the transmission rod 2 and drives the slag removal plate 4 to turn over. A width adjustment device is arranged between the slag removal plates 4.

[0022] During the plasma cutting process, the saw blade will be placed on the heat sink 14 on the machine tool 6. The heat sink 14 below it can reduce the contact area between the saw blade and the machine tool 6 and effectively improve the air flow under the saw blade. After the saw blade is cut by plasma, slag will be left on the upper end and side wall of the heat sink 14. When removing the slag, the worker first places the bottom frame 1 on the upper end surface of the heat sink 14, adjusts the width of the slag removal plate 4 through the width adjustment device, and makes the two ends of the slag removal plate 4 contact with the side walls of the heat sink 14. Finally, the pry bar 3 drives the slag removal plate 4 to flip over, and makes the slag removal plate 4 quickly scrape off the slag on the heat sink 14.

[0023] The preferred solution is Figure 2 As shown, bases 5 are arranged in parallel on both sides of the bottom frame 1, and both ends of the transmission rod 2 are plugged into the bases 5. Baffles 7 are arranged at both ends of the transmission rod 2 and can rotate around their own axes. The transmission rod 2 is connected to the pry bar 3, which increases the torque and achieves a labor-saving effect.

[0024] The preferred solution is Figure 2 As shown, the slag removal plate 4 includes a sleeve plate 401, a telescopic plate 402 and a scraper 403; the upper end surface of the sleeve plate 401 is fixedly connected to the outer wall of the transmission rod 2 through a connecting rib 8, the sleeve plate 401 is plugged with telescopic plates 402 on both sides, and the side of the telescopic plate 402 is provided with a scraper 403, and the upper and lower ends of the scraper 403 are obliquely designed, and the telescopic plate 402 can slide left and right along the sleeve plate 401 and adjust the width of the slag removal plate 4;

[0025] During use of the tooling, the extension distance of the telescopic plate 402 can be adjusted through the width adjustment device, and then the width of the slag removal plate 4 is adjusted according to the spacing of the heat sink 14, so that the scrapers 403 on both sides of the telescopic plate 402 can contact the heat sink 14, and the slag on the heat sink 14 can be quickly scraped off through the oblique plates at the upper and lower ends of the scrapers 403.

[0026] The preferred solution is Figure 3As shown, the width adjustment device includes a transmission gear 11 and a toothed plate 12, the transmission gear 11 is arranged in the sleeve plate 401 and can rotate freely, the transmission gear 11 is installed between the telescopic plates 402, the upper end of the transmission gear 11 is vertically connected to the connecting column 10, the other end of the connecting column 10 extends out of the sleeve plate 401 and is connected to the knob 9; the side wall of the telescopic plate 402 is vertically connected with the toothed plate 12, the toothed plate 12 is meshed and connected with the transmission gear 11, the transmission gear 11 rotates and drives the toothed plate 12 and the telescopic plate 402 to slide left and right; the side wall of the telescopic plate 402 is correspondingly provided with a slot 13 for placing the transmission gear 11 and the toothed plate 12;

[0027] When the width of the slag removal plate 4 needs to be increased, the knob 9 can be rotated clockwise, and the knob 9 drives the transmission gear 11 to rotate clockwise synchronously. The clockwise rotation of the transmission gear 11 drives the toothed plate 12 to slide outward, and then drives the telescopic plate 402 to slide outward synchronously;

[0028] When the width of the slag removal plate 4 needs to be reduced, the knob 9 can be rotated counterclockwise, and the knob 9 drives the transmission gear 11 to rotate counterclockwise synchronously. The counterclockwise rotation of the transmission gear 11 drives the tooth plate 12 to slide inward, and then drives the telescopic plate 402 to slide inward synchronously until the telescopic plate 402 is completely retracted to the sleeve plate 401. At this time, the tooth plate 12 and the transmission gear 11 will be retracted into the slot 13 and the recovery is completed.
