Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to a cutting machine for processing sheet metal parts. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is consistent. In the process of processing sheet metal parts, laser cutting machines are often used to perform laser cutting processing on sheet metal parts. After searching, the patent document with authorization announcement number CN217859396U announced a laser cutting device for preparing sheet metal parts, including a laser cutting device body and a bottom plate. The laser cutting device body is installed on the top of the bottom plate, and the top of the bottom plate is fixedly connected with a fixed frame. The top of the fixed frame is rotatably connected with multiple slides, and the multiple slides are slidably connected with slide rods. The other ends of the multiple slide rods are fixedly connected with rotating seats. Each adjacent two rotating seats are slidably connected with a slide. The opposite ends of the two slides are installed with a first motor, and the output ends of the two first motors are fixedly connected with a clamping frame. The top of the fixed frame is installed with two first electric cylinders, and the output ends of the two first electric cylinders are respectively fixedly connected with the two slides. A dust suction mechanism is installed on the top of the bottom plate.

[0003] The above-mentioned related schemes are found to still have at least the following deficiencies in actual operation: when laser cutting sheet metal parts, although the sheet metal parts can be clamped and fixed to prevent deviation during cutting and improve cutting accuracy, each sheet metal part needs to be clamped and fixed and removed once. When cutting batches of sheet metal parts one by one, the operation process is cumbersome and time-consuming, the working time is long, and the work efficiency is relatively low.

[0029] In this embodiment, the guide mechanism includes two cushion seats 10, two first electric telescopic rods 11 and two guide plates 12. The two cushion seats 10 are fixedly mounted on the top of the platform 1 and symmetrically distributed on the front and rear sides of the conveying trough 2.

By utilizing the telescopic characteristics of the first electric telescopic rod 11, the guide plate 12 can be moved horizontally and linearly. By adjusting the spacing between the two guide plates 12 to be slightly larger than the width of the sheet metal component (that is, the distance between the guide plate 12 and the edge of the sheet metal component can be set to 1-3mm), the sheet metal component can be ensured to move horizontally and linearly on the conveyor belt 3. The above-mentioned pressing mechanism includes a crossbeam 14, a second electric telescopic rod 15 and a pressing plate 16.

By utilizing the telescopic characteristics of the third electric telescopic rod 18, the baffle 19 can be controlled to move horizontally and linearly, and the vertical distance between the baffle 19 and the laser cutting head can be adjusted. The vertical distance between the baffle 19 and the laser cutting head is the cutting length, and the vertical distance between the baffle 19 and the laser cutting head can be manually measured using a measuring ruler.

[0030] In this embodiment, a plurality of balls 13 are nested at even intervals at the bottom of the two guide plates 12, and the plurality of balls 13 are in rolling contact with the upper surface of the conveyor belt 3. The rolling contact between the plurality of balls 13 and the upper surface of the conveyor belt 3 can ensure that the side parts of the sheet metal parts will not be inserted into the gap between the guide plates 12 and the conveyor belt 3, and ensure smooth rotation of the conveyor belt 3.

[0031] In this embodiment, a rubber pad is fixedly installed at the bottom of the pressing plate 16 to protect the pressing part of the sheet metal component and prevent the pressing plate 16 from applying excessive pressure to the sheet metal component and damaging the surface of the sheet metal component.

[0032] In this embodiment, an inclined guide plate 20 is fixedly installed in the conveying trough 2 and is located on the right side of the conveyor belt 3.

[0034] Through the above structure, the cutting machine for sheet metal parts processing provided by the present application can horizontally and linearly transport sheet metal parts when in use, and is suitable for laser cutting batches of sheet metal parts one by one. The operation is simple and convenient, reduces manual labor, saves working time, and improves work efficiency. Sheet metal parts can be cut to a fixed length according to needs to ensure that the cutting length of each sheet metal part is the same. During specific operation, according to the width size of the sheet metal parts, the spacing between the two guide plates 12 can be adjusted by controlling the extension of the two first electric telescopic rods 11, and the spacing between the two guide plates 12 can be adjusted to 2-6mm larger than the width size of the sheet metal parts. By controlling the extension or contraction and reset of the third electric telescopic rod 18, the position of the baffle 19 can be horizontally and linearly adjusted, that is, the vertical spacing size between the baffle 19 and the laser cutting head can be changed (this spacing size is the cutting length). By controlling the extension of the electric hydraulic cylinder 7, the mounting plate 8 and the laser cutting machine 9 can be controlled to vertically descend to a suitable height position. After the above adjustment preparation work is completed , and then control the conveyor belt 3 to rotate, put the sheet metal parts one by one on the conveyor belt 3 and between the two guide plates 12, and use the conveyor belt 3 to transport the sheet metal parts horizontally to the right. When the right side of the sheet metal parts hits the baffle 19, stop the rotation of the conveyor belt 3, and then control the third electric telescopic rod 18 to extend and run until the rubber pad at the bottom of the pressure plate 16 presses the sheet metal parts, and then start the laser cutting machine 9 and control the electric slide 6 to slide on the electric guide rail 5, and use the laser beam emitted by the laser cutting machine 9 to laser the sheet metal parts. Light cutting, after the cutting is completed, stop the electric slide 6 from sliding and turn off the laser cutting machine 9, control the second electric telescopic rod 15 to retract and reset so that the pressing plate 16 rises back to its position, and the cut sheet metal parts slide out of the conveying trough 2 along the inclined direction of the inclined guide plate 20, and then continue to control the conveyor belt 3 to rotate and continue to convey the sheet metal parts. According to the above operating steps, the sheet metal parts can be cut one by one, and the sheet metal parts can be cut to a fixed length without changing the position of the baffle 19, ensuring that the cutting length of each sheet metal part is the same.
