Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cutting, in particular to a high-efficiency steel plate cutting device. 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, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece. During the production and processing of steel plates, laser cutting equipment is needed to cut and truncate.

[0003] In the prior art, an authorized patent with announcement number CN 218926599 U discloses a steel plate laser cutting device, comprising a workbench, symmetrically provided with support columns, a rotatable threaded rod disposed between the two support columns, a sliding block threadedly connected to the threaded rod, a limit rod passing through the sliding block, and a laser cutting head connected to the bottom end of the sliding block; a clamping mechanism symmetrically disposed on both sides of the sliding block, the clamping mechanism comprising a support frame, each elastically connected to a plurality of outer rods, each elastically connected to an inner rod, the top end of each inner rod passing through the support frame, and trigger blocks symmetrically disposed on both sides of the sliding block that cooperate with the inner rods. Thus, the utility model can automatically adapt to the shape of the steel plate and quickly secure the steel plate to be cut, thereby improving the stability of the steel plate during the cutting process.

[0004] However, the above technical solution still has the following shortcomings during use: because the bottom ends of multiple outer rods of the above laser cutting device are close to the workbench surface, when placing the steel plate to be cut, it is necessary to push the steel plate to squeeze the outer rod to make it shrink before the steel plate can be placed under the outer rod. This is inconvenient to operate and has low processing efficiency. When processing some thicker steel plates, it is easy to hit the outer rod during placement, causing compression damage. In this regard, we have proposed a high-efficiency steel plate cutting device. Utility Model Content

[0019] The two ends of the two movable seats 4 are slidably connected to the two ends of the support rods 3 through the through holes opened. Two mounting seats 5 are provided on the processing table 1. A driving mechanism 6 is installed on the two mounting seats 5. A laser cutting head 7 is installed on the driving mechanism 6. A portal frame 8 is provided on the front and rear sides of the driving mechanism 6. The two ends of the portal frame 8 are respectively fixedly welded on the two mounting seats 5. A plurality of clamping mechanisms 9 are installed on the portal frame 8. The driving mechanism 6, the laser cutting head 7 and the clamping mechanism 9 are all existing public technologies, so the detailed structure is not repeated. A pair of push-pull rods 10 are rotatably installed on the outer walls of the two mounting seats 5 through a rotating connection. The two pairs of push-pull rods 10 are rotatably installed on the two movable seats 4 at one end away from the mounting seat 5.

[0020] An L-shaped support frame 11 is fixedly mounted on one side wall of the processing table 1 , and a servo motor 12 is fixedly mounted on the L-shaped support frame 11 . The output end of the servo motor 12 is transmission-connected to the bidirectional screw 2 , so that the servo motor 12 can drive the bidirectional screw 2 to rotate.

[0021] A pair of positioning seats 13 are provided below the two mounting seats 5. The positioning seats 13 are fixedly welded to the side walls of the processing table 1. A pair of positioning rods 14 are fixedly welded to the bottom wall of the mounting seat 5. The positioning rods 14 are slidably connected to the positioning seats 13.
