Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a cutting device for sheet metal processing. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology. We cannot live without sheet metal parts in our lives. They have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), good performance in large-scale mass production, etc. They have been widely used in electronics, communications, automobile industry, medical equipment and other fields.

[0003] For example, a Chinese patent (publication number: CN220515764U) discloses a cutting device for sheet metal processing, which includes an operating table, a support frame is fixedly installed on the upper surface of the operating table, a linear slide is arranged on the support frame, and a laser cutting head for cutting the sheet metal body is arranged on the outer side of the linear slide. The upper surface of the operating table is provided with a clamping mechanism for fastening the position of the sheet metal body. After the clamping mechanism of the utility model fastens the sheet metal body, the linear slide, the laser cutting head and the cleaning mechanism are started simultaneously. As the linear slide drives the laser cutting head to move in position to cut the sheet metal body, the generated smoke and dust can be effectively absorbed and concentrated in the interior of the concentration pipe during the process of being lifted or fallen, and then circulated through the guide pipe to the smoke filter element inserted in the filter cartridge, thereby effectively absorbing and collecting the generated smoke and dust without delaying the subsequent processing of the sheet metal body.

[0004] The above-mentioned cutting device for sheet metal processing still has certain shortcomings. The sheet metal body is directly inserted into the interior of the U-shaped groove, and then the screw is engaged and rotated inside the threaded hole, so that the pressure plate can be directly squeezed on the upper surface of the sheet metal body, thereby effectively fixing the position of the sheet metal body. Since the distance between the two U-shaped grooves cannot be adjusted, shorter sheet metals cannot be fixed, which affects the processing of the sheet metal parts. Moreover, fixing by rotating the lever is not only time-consuming and labor-intensive, but also has a poor fixing effect. Therefore, the present application proposes a cutting device for sheet metal processing to solve the above-mentioned problems. Utility Model Content

[0018] By adopting this technical solution, waste chips generated after cutting sheet metal parts can be collected.

[0019] Furthermore, the second suction pipe is U-shaped, and a dust collector head is fixed below two opposite sides of the second suction pipes.

[0045] The working principle of the above embodiment is:

[0046] (1) When it is necessary to fix the sheet metal, first place the sheet metal on the workbench and start the motor 301.

The moving block 309 drives the top plate 311 to move together through the connecting rod 310. After the top plate 311 moves to the appropriate position, the first electric push rod 312 is started. The first electric push rod 312 drives the pressure plate 313 to move, so that the pressure plate 313 clamps and fixes the sheet metal to prevent the sheet metal from moving during processing and affecting the cutting effect.

[0047] (2) When cutting the sheet metal, start the fan 404, and the fan 404 sucks the dust and waste into the second suction pipe 406 through the suction head. The dust and waste in the second suction pipe 406 will enter the collection box 401. The dust and waste will remain in the collection box 401 under the action of the filter 402. The excess air will enter the first suction pipe 403 and enter the air outlet pipe 405 through the first suction pipe 403, and finally be discharged through the air outlet pipe 405, so as to facilitate the collection of dust and waste and prevent the waste from remaining on the workbench and affecting the processing of the sheet metal.
