Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a material rack lifting device for a laser cutting machine. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize or reach its ignition point. At the same time, a high-speed airflow coaxial with the beam is used to blow away the molten material, thereby cutting the workpiece. It is one of the thermal cutting methods for cutting workpieces, so a material rack lifting device is required for laser cutting machines.

[0003] According to the description of a material rack lifting device for a laser cutting machine disclosed on the patent website (authorization announcement number: CN220575026 U), "The utility model discloses a material rack lifting device for a laser cutting machine, which relates to the technical field of laser cutting machines. The utility model includes a frame, a lifting mechanism and a clamping mechanism. The lifting mechanism includes a screw rod, a screw rod support frame, a motor and a lifting platform. The clamping mechanism includes a splint, a rotating rod, a hinge, a slider and a hydraulic telescopic device. Compared with the existing technology, the utility model greatly reduces the difficulty of loading materials for workers by setting a lifting mechanism, making the material more stable and not easy to slip during the upward movement. By setting a clamping mechanism, the material does not move when the laser cutting machine is working, thereby improving the cutting accuracy and improving the operation safety at the same time."

[0004] In response to the above description, the applicant believes that the following problems exist: when the device is used, a lifting mechanism is set up, which greatly reduces the difficulty of loading materials for the staff, allowing the materials to be moved smoothly to the work surface. At the same time, an anti-slip coating is provided on the surface of the lifting platform to increase the friction, making the material more stable during the upward movement and not easy to slip. When cutting metal plates, the device requires manual transportation of the plates to the lifting platform for cutting, and then manually pushing the plates to the bottom of the cutting machine for cutting. The operation steps are very cumbersome. Utility Model Content
