Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a laser knife die for numerical control cutting. Background Art

[0002] Laser cutting uses high-power density laser media to irradiate the cutting material, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the laser medium moves on the material, the holes continuously form a very narrow cut, completing the cutting of the material.

[0003] Among them, the patent with announcement number CN211708365U discloses a fixed light laser die cutting machine, which relates to the field of mold making, packaging and printing technology, including a frame, an operating table is arranged on the frame, a laser head cover is arranged on one side of the frame, an aluminum profile bracket is arranged on the front of the frame, a guide rail one is arranged on one side of the frame, an aluminum profile is installed on the frame, a guide rail two is arranged on the aluminum profile, a crossbeam is arranged on the guide rail one, a wooden board bracket is arranged on the crossbeam, a drag chain is arranged on the wooden board bracket, a drag chain support plate is arranged on the drag chain, a reflector support frame is arranged on the inner side of the frame, a reflector is arranged on the reflector support frame, and a laser head frame is arranged under the reflector support frame.

[0004] When this structure is in use, the fixed light laser die cutting machine uses plate movement, and the movement in the X and Y directions is only the movement of the cutting material, and the workbench does not need to move, which reduces the distance from the laser transmitter to the machine tool and keeps it at the same distance. The machine load weight is reduced during cutting movement, so that the laser cutting can move quickly, and the machine load weight will not increase due to the movement of the workbench. When cutting materials, only the material is moving, and the workbench does not need to move back and forth, which reduces the load weight of the servo motor and makes the machine faster when cutting. However, this structure is not easy to focus the laser medium, resulting in low quality of the laser medium during cutting, affecting the cutting efficiency. Summary of the invention

[0005] The present invention provides a laser knife die for numerical control cutting, aiming to solve the problems raised in the above background technology.

[0006] The present invention is implemented in this way. The present invention provides the following technical solutions: a laser knife die for numerical control cutting, comprising a base, on which a focusing cutting component is arranged.

[0007] The focus cutting assembly includes a connecting ring arranged on one side of the base, a rotating ring for placing a workpiece is rotatably connected to the connecting ring, a light pump is arranged on one side of the rotating ring, and a regulator for regulating the light pump power is arranged on the light pump.

[0008] A focusing head is arranged at one end of the optical pump, and a first laser head is embedded at one end of the focusing head.

[0009] A support sleeve is provided on the outer side of the focusing head, and a plurality of extension frames for support are distributed on the support sleeve. A second laser head is provided on one side of the plurality of extension frames, and a refractive head is provided on one end of each of the second laser heads. A threaded sleeve is fixedly provided on the end of the focusing head facing the regulator, and the threaded sleeve extends to the regulator and is threadedly connected to the regulator. A limiting member is fixedly provided on one side of the extension frame, and a baffle is fixedly provided on one end of the limiting member. A limiting cavity is provided on the outer side of the limiting member, and the second laser head matches the limiting cavity. The second laser head is embedded in the limiting cavity, and a through hole is provided on the surface of the baffle, and one end of the refractive head extends into the through hole. A locking sleeve is provided on the outer side of the refractive head, and a docking block is fixedly provided on the locking sleeve. The docking block is located on one side of the top of the inner cavity of the limiting cavity, and the docking block extends to the bottom of the baffle.

[0010] It can be seen that in the above technical solution, the filter of the optical pump is adjusted by the regulator, and the laser emitted by the optical pump is used to focus the original laser medium emitted by the optical pump through the focusing head to form a high-energy-density light spot, while the first laser head is used to change the condition of the cutting beam ejection, control the area and size of the laser medium diffusion, and ensure the cutting quality. When the laser medium is exported, each second laser head is used to guide the laser medium to the laser medium ejected by the first laser head, and then change the curvature of the laser medium ejected by the first laser head. By changing the curvature of the laser medium, the divergence angle of the reflected light beam is changed, thereby changing the focal position and realizing the function of automatic focusing, which can save a lot of time and improve the efficiency of laser cutting. Each baffle is tilted toward the axis pin point of the support sleeve, so that the laser medium ejected by the second laser head can be refracted on the laser medium ejected by the first laser head. At the same time, by rotating the threaded sleeve, the position of the focusing head and the first laser head at one end of the regulator is adjusted to realize dynamic adjustment of the focal position and focal length, which is easy to be used for cutting on different materials or thicknesses, and can improve cutting quality and efficiency.

[0011] Optionally, in a possible embodiment, a support frame is provided on one side of the connecting ring, and the support frame is installed on the base by bolts, a first slide is slidably connected to the support frame, a second slide is slidably connected to the first slide, a third slide is provided on the top of the second slide, an electric slide rail for driving the third slide to move is provided on the second slide, the light pump is installed on the third slide by bolts, a first screw transmission module for driving the first slide to move is provided at one end of the support frame, a second screw transmission module for driving the second slide to move is provided at one end of the first slide, and the plurality of baffles are distributed along the circumference of the axis center point of the support sleeve, and each of the baffles is inclined toward the pivot point of the support sleeve.

[0012] It can be seen that in the above technical solution, the rotating ring can also rotate on the connecting ring, which is convenient for cutting and processing different positions of the workpiece. At the same time, the first slide is driven by the first screw transmission module to slide on the support frame, and the second screw transmission module, the second slide and the optical pump are first position-adjusted. After the second screw transmission module is started, the second slide can slide on the first slide. At the same time, the third slide is driven by the electric slide rail to extend on the second slide, so that the optical pump can be position-adjusted again to achieve diversity and convenience when cutting the workpiece. After the locking sleeve, the docking block and the limit cavity are set, the second laser head is conveniently embedded in the limit cavity. The docking block can be located at the bottom of the baffle, realizing the function of positioning the second laser head after installation, avoiding the displacement of the second laser head and the refractive head, which causes the laser medium ejected by the second laser head to be unable to be transmitted to the laser medium ejected by the first laser head.

[0013] The present invention has the following advantages: 1. The present invention adjusts the filtering of the optical pump through the controller. The laser emitted by the optical pump is used to focus the original laser medium emitted by the optical pump through the focusing head to form a light spot with high energy density, and the first laser head is used to change the state of the cutting beam ejection, control the area and size of the laser medium diffusion, and ensure the cutting quality; 2. Each second laser head of the present invention is used to guide the laser medium to the laser medium ejected by the first laser head, and then change the curvature of the laser medium ejected by the first laser head. By changing the curvature of the laser medium, the divergence angle of the reflected light beam is changed, thereby changing the focal position and realizing the function of automatic focusing, which can save a lot of time and improve the efficiency of laser cutting; 3. Each baffle of the present invention is tilted toward the pivot point of the support sleeve, so that the laser medium ejected by the second laser head can be refracted on the laser medium ejected by the first laser head. At the same time, by rotating the threaded sleeve, the positions of the focusing head and the first laser head at one end of the regulator are adjusted to achieve dynamic adjustment of the focus position and focal length, which is easy to be used for cutting on different materials or thicknesses, and can improve cutting quality and efficiency; 4. The present invention is provided with a locking sleeve, a docking block and a limiting cavity, so that after the second laser head is embedded in the limiting cavity, the docking block can be located at the bottom of the baffle, realizing the function of positioning the second laser head after installation, and avoiding displacement of the second laser head and the refractive head, which causes the laser medium ejected by the second laser head to be unable to be transmitted to the laser medium ejected by the first laser head; 5. The present invention can rotate on the connecting ring through the rotating ring, which is easy to cut and process different positions of the workpiece. The first slide slides on the support frame, and the second screw drive module, the second slide and the optical pump are first adjusted in position. The electric slide rail drives the third slide to extend on the second slide, so that the optical pump can be adjusted in position again, so as to achieve diversity and convenience when cutting and processing the workpiece; To sum up, through the corresponding coordinated use of each structure, the laser emitted by the optical pump is used to focus the original laser medium emitted by the optical pump through the focusing head to form a high-energy density light spot, and the first laser head is used to change the condition of the cutting beam ejection, control the area and size of the laser medium diffusion, and ensure the cutting quality.

At the same time, by rotating the threaded sleeve, the position of the focusing head and the first laser head at one end of the regulator is adjusted to realize dynamic adjustment of the focal position and focal length, which is easy to be used for cutting on different materials or thicknesses, and effectively ensures the cutting quality and efficiency.

A through hole 14 is formed on the surface of the baffle 12, and one end of the refractive head 17 extends into the through hole 14. A locking sleeve 16 is sleeved on the outer side of the refractive head 17, and a docking block 18 is fixedly provided on the locking sleeve 16. The docking block 18 is located on one side of the top of the inner cavity of the limiting cavity 13, and the docking block 18 extends to the bottom of the baffle 12.

[0029] A support frame 19 is provided on one side of the connecting ring 2, and the support frame 19 is installed on the base 1 by bolts.
