Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and more specifically, to a laser cutting device. Background Technology

[0002] In the traditional VC stainless steel mesh cutting process, die stamping is commonly used. This method maintains high cutting accuracy and efficiency when the number of stamping passes is low. However, as the number of stamping passes increases, the die edge gradually dulls, leading to non-compliant cut shapes and problems such as die jamming and mesh jamming. These issues not only affect the quality of the VC stainless steel mesh cutting but may also prevent subsequent automated processes, thus reducing overall production efficiency. Therefore, we have proposed an improvement: a laser cutting device. Utility Model Content

The lifting cylinder 302 can drive the starting gripper 303 to rise and fall, so that after the starting gripper 303 clamps the clamping rod 305 through the clamping arm 304, the lifting cylinder 302 can drive the contouring mold 306 to rise and fall.

[0035] Furthermore, such as Figure 1 As shown, an air shaft 4 is provided below the laser 101. The air shaft 4 is connected to a driving component, which is used to drive the air shaft 4 to rotate in order to unwind the raw material.

Both the output shaft of the motor 401 and the air shaft 4 are provided with synchronous pulleys, and a synchronous belt connects the two synchronous pulleys. Both the air shaft 4 and the motor 401 are also provided with mounting holes. Bolts can be used to pass through the mounting holes to install the motor 401 and the air shaft 4 onto the existing frame to support the motor 401 and the air shaft 4.

[0038] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the gas supply structure 5 includes a support member connected to a hollow seat 503. Two supply pipes 505 are connected to the side of the hollow seat 503 near the contour mold 306, and each of the two supply pipes 505 has an air outlet 506 at its bottom. The two hollow seats 503 are located on both sides of the contour mold 306, and the air outlet 506 is used to blow out a protective gas, which can be nitrogen.

[0039] Furthermore, such as Figure 1 As shown, the top of the hollow base 503 is connected to a connecting pipe 504. The connecting pipe 504 is used to connect to a protective gas source through a pipeline for gas protection during cutting and can blow away the debris generated during the cutting process.

[0040] Furthermore, such as Figure 1 and Figure 4 As shown, a connecting plate 502 is connected to one side of the hollow base 503, and a second mounting base 501 is connected to the connecting plate 502. The second mounting base 501 is also provided with mounting holes, and bolts can be used to pass through the mounting holes to install the second mounting base 501 onto the existing frame to support the gas transmission structure 5.

[0041] Third mounting bases 601 are provided on both sides of the support plate 2, between the second mounting base 501 and the motor 401, and below the air shaft 4. Guide rollers 6 are connected to the third mounting bases 601, and the guide rollers 6 also have mounting holes. Bolts can be passed through these holes to mount the guide rollers 6 onto the existing frame to support the guide rollers 6 and the third mounting bases 601.

Then, the gripper 303 is activated to drive the gripper arm 304 away from the gripper rod 305. Protective gas enters through the connecting pipe 504, passes through the hollow seat 503 and the conveying pipe 505, and is then ejected from the outlet 506 to the contour mold 306. The laser beam is emitted from the laser lens 102 onto the raw material for laser cutting. The laser path cuts along the outer ring of the contour mold 306 to cut out the VC stainless steel mesh. C stainless steel mesh, then start the gripper 303 to drive the gripper arm 304 to clamp the gripper rod 305, the lifting cylinder 302 drives the gripper 303 to rise, which in turn drives the molding die 306 to rise, so that the molding die 306 separates from the raw material and the raw material moves, the lifting cylinder 302 drives the gripper 303 to fall, which in turn drives the molding die 306 to fall, so that the molding die 306 presses on the raw material, then start the gripper 303 to drive the gripper arm 304 to release the gripper rod 305, and continue cutting.
