Description

Technical Field

[0001] This invention relates to the field of wire mesh cutting technology, specifically to a laser cutting device for wire products. Background Technology

[0002] Steel wire mesh is a mesh-like material made of low-carbon steel wire, stainless steel wire, and other wires through processes such as weaving and welding. It is mainly used for protection, filtration, and support.

[0003] In practical applications, wire mesh requires segmented cutting. In existing technologies, when the rolled wire mesh is placed on a cutting machine, the cut sections must be removed after cutting, and the section to be cut must be pulled out, fixed, and positioned before further cutting. This process reduces cutting efficiency. Furthermore, the ends of the wire mesh droop after each cut, requiring them to be lifted before the next cut. Therefore, we propose a laser cutting device for wire products to address these shortcomings. Summary of the Invention

[0030] The top rod 910 has a support shaft 911 symmetrically and fixedly connected to the middle of both sides. The bottom of the support shaft 911 abuts against the side of the frame 902. The bottom of both sides of the top rod 910 has a lever shaft 912 symmetrically and fixedly connected to the bottom.

[0034] The unloading mechanism 11 includes a fixed frame 1101 fixedly installed on one side of the machine base 1. The fixed frame 1101 is close to the dragging mechanism 10. A fixed roller 1102 and a movable roller 1103 are rotatably arranged on the fixed frame 1101. A return spring 1104 is provided at the top of the connection between the movable roller 1103 and the fixed frame 1101.

[0035] A drive motor 1105 is provided on the side of the fixed frame 1101, and gears 1106 are fixedly connected to the sides of both the fixed roller 1102 and the movable roller 1103, and the two gears 1106 mesh with each other.

[0036] An electric cylinder 1107 is provided on the side of the movable roller 1103, and the output shaft of the electric cylinder 1107 is rotatably connected to the side of the movable roller 1103.

[0037] In this embodiment, firstly, the wire mesh is released from the wire mesh release roller 2, guided and leveled between two positioning pressure rollers 3, allowing the wire mesh to smoothly enter the support frame 4 area. The wire mesh is laid above the pad strip 5, and the spring telescopic rod 7 drives the pressure strip 6 to press down on the edge of the wire mesh, keeping the wire mesh flat, without warping or displacement in the cutting area, providing stable support for subsequent cutting. The wire mesh passes through the dragging mechanism 10 and enters above the circular roller 1002 of the front frame 1001. The electric cylinder 1005 is activated, pushing the adjusting frame 1004 downward, causing the meshing pressure plate 1003 to press against the surface of the wire mesh, utilizing the meshing structure to bite the wire mesh. The wire mesh is reliably clamped together. Then, the drive slide rail 8 drives the cutting frame 901 and the front frame 1001 to move synchronously, dragging the wire mesh forward to the position close to the unloading mechanism 11 according to the set length, completing the feeding and positioning. After the wire mesh is in place during the movement and cutting stage of the laser cutting head 906, the transmission component 904 drives the slider 905 to move laterally along the frame 902, driving the laser cutting head 906 to move along the preset path, performing laser cutting on the wire mesh inside the frame 902 and the through-hole 903 area to form a finished mesh of the set size. During the cutting process, the frame 902 supports the bottom of the wire mesh to prevent the mesh from shifting due to cutting vibration.

[0038] In this embodiment, after the wire mesh is cut, the cutting lifting mechanism 9 drives the slide rail 8 to continue moving the cutting frame 901, so that the top of the top rod 910 contacts the lifting bar 914 on the side frame 913. The curved section of the lifting bar 914 gradually lifts the top rod 910 upward. The top rod 910 drives the two side support shafts 911 and the dial shaft 912 to move upward synchronously. The dial shaft 912 pushes the swing arm 907 upward, so that the swing arm 907 swings upward around the hinge point. The dial bar 908 at the end of the swing arm 907 is lifted upward, lifting the uncut wire mesh end upward to prevent the wire mesh from falling downward. During the continuous movement, the end of the wire mesh is inserted between the round roller 1002 and the meshing plate 1003. At this time, the round roller 1002 and the meshing plate 1003 are in a state of being far away from each other.

[0039] In this embodiment, after the wire mesh is cut, the unloading mechanism 11 operates. At this time, the circular roller 1002 and the meshing pressure plate 1003 are in a state of being far apart from each other, releasing the clamping of the wire mesh. The drive motor 1105 starts, and through the meshing gears 1106, it drives the fixed roller 1102 and the movable roller 1103 to rotate synchronously, smoothly conveying the cut mesh outward and separating it from the cutting area, thus realizing automatic unloading. When the wire mesh to be cut is dragged closer again, the end of the wire mesh is located between the fixed roller 1102 and the movable roller 1103. At this time, the output shaft of the electric cylinder retracts, controlling the movable roller 1103 to move closer to the fixed roller 1102 to clamp the wire mesh, so as to perform the unloading operation after cutting again.

[0040] The method of use and advantages of this invention: This laser cutting equipment for steel wire products operates as follows:

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown:

[0042] S1: After being guided and leveled by the release roller and positioning pressure roller 3, the wire mesh enters the support frame 4. The edge is pressed and positioned by the pad strip 5, pressure strip 6 and spring telescopic rod 7 to ensure that the cut surface is flat. The dragging mechanism 10 clamps the wire mesh with the round roller 1002 through the meshing pressure plate 1003. Under the drive of the drive slide rail 8, the mesh body is dragged to the cutting station to achieve fixed-length feeding.

[0043] S2: After the cutting frame 901 moves into place, the transmission component 904 drives the slider 905 and the laser cutting head 906 to move laterally along the frame 902 to perform laser cutting on the wire mesh in the through area 903. The frame 902 supports the bottom of the mesh to suppress cutting vibration and ensure stable cutting dimensions.

[0044] S3: After cutting is completed, the drive slide rail 8 continues to drive the cutting frame 901 to move. The top rod 910 is lifted upward along the curved section of the lifting bar 914. The swing arm 907 and the lever 908 are pushed upward by the pivot shaft 912 to lift the uncut wire mesh end to prevent it from falling and to ensure that the subsequent end can smoothly enter the clamping area of ​​the dragging mechanism 10.

[0045] S4: The cut mesh is clamped by the fixed roller 1102 and the movable roller 1103 of the unloading mechanism 11, and rotated out under the drive of the gear 1106.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
