Description

Technical Field

[0001] The present invention relates to the field of laser cutting machinery, and particularly to a material taking device for a laser cutting machine. Background Art

[0002] After a large metal plate is laser cut, several small metal blocks are formed. Generally, a plate suction clamp 200 (as Figure 1 shown) is used to suck away the small metal blocks. The specific use steps are as follows: Hold the upper handle 210 and the lower trigger 220 of the plate suction clamp 200 (as Figure 1 shown) to lift the small metal block. After moving the small metal block to a designated position, pull the lower trigger 220 of the plate suction clamp 200, so that the magnet 230 moves upward against the elastic force of the return spring 250. The small metal block is separated from the magnet 220 and falls off due to the blockage of the sleeve 240 outside the magnet 230. After the small metal block falls off, remove the trigger force, and the lower trigger 220 returns under the action of the return spring 250.

[0003] During the process of the plate suction clamp sucking and moving the small metal block, the gravity direction of the small metal block and the acting force held by hand are not in the same vertical plane. Due to the lever principle, a relatively large force is required by hand to lift the small metal block. Therefore, the weight that the small metal block can lift is limited to a certain extent; in addition, the suction force of the magnet 230 is relatively large, and it is rather laborious to pull the lower trigger 220, and even knocking is required to make the small metal block fall off, resulting in a low material taking efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a material taking device for a laser cutting machine to solve the above technical problems.

[0005] To achieve the above object, the technical solution of the present invention is: to provide a material taking device for a laser cutting machine, including a hand-held cross bar, a magnet mounting cross bar, a rotatably connected vertical bar, a trigger and material discharging bar, a magnet and a return spring. The hand-held cross bar is located above the magnet mounting cross bar, and the hand-held cross bar and the magnet mounting cross bar are parallel to each other. The upper end of the rotatably connected vertical bar is fixedly connected to the left end of the hand-held cross bar, and the lower end of the rotatably connected vertical bar is fixedly connected to the left end of the magnet mounting cross bar. The magnet is fixedly installed at the bottom of the magnet mounting cross bar. The rotatably connected vertical bar is provided with a rotation mounting hole penetrating through itself from left to right. The trigger and material discharging bar includes a rotation connection part, a trigger part extending rightward and downward from the right end of the rotation connection part, and a material pushing part extending leftward and downward from the left end of the rotation connection part. The trigger and material discharging bar is inserted through the rotation mounting hole, and the front and rear outer side walls of the rotation connection part are respectively rotatably connected to the front and rear inner side walls of the rotation mounting hole. The trigger part extends between the hand-held cross bar and the magnet mounting cross bar, and the material pushing part extends to the left side of the magnet. The upper end of the return spring is fixed on the rotatably connected vertical bar above the rotation connection part or fixed on the hand-held cross bar, and the lower end of the return spring is fixed on the material pushing part. When the trigger part is pulled upward, the lower end of the material pushing part can rotate to the lower side of the bottom of the magnet.

The hand-held vertical bar is arc-bent rightward.

[0016] Reference Figures 2 to 3 , the material taking device 100 of the laser cutting machine of the present invention includes a hand-held cross bar 10, a magnet mounting cross bar 20, a rotary connecting vertical bar 30, a buckle and material discharging bar 40, a magnet 50 and a return spring 60.

[0017] The hand-held cross bar 10 is located above the magnet mounting cross bar 20, and the hand-held cross bar 10 is parallel to the magnet mounting cross bar 20. The upper end of the rotary connecting vertical bar 30 is fixedly connected to the left end of the hand-held cross bar 10, and the lower end of the rotary connecting vertical bar 30 is fixedly connected to the left end of the magnet mounting cross bar 20. The magnet 50 is fixedly installed at the bottom of the magnet mounting cross bar 20. The rotary connecting vertical bar 30 is provided with a rotary mounting hole 31 penetrating through itself from left to right. The buckle and material discharging bar 40 includes a rotary connecting portion 41, a buckle portion 42 extending rightward and downward from the right end of the rotary connecting portion 41, and a material ejecting portion 43 extending leftward and downward from the left end of the rotary connecting portion 41. The buckle and material discharging bar 40 is inserted through the rotary mounting hole 31, and the front and rear outer side walls of the rotary connecting portion 41 are respectively rotatably connected to the front and rear inner side walls of the rotary mounting hole 31. The buckle portion 42 extends between the hand-held cross bar 10 and the magnet mounting cross bar 20. The material ejecting portion 43 extends to the left side of the magnet 50. The upper end of the return spring 60 is fixed on the rotary connecting vertical bar 30 above the rotary connecting portion 41. The lower end of the return spring 60 is fixed on the material ejecting portion 43. When the buckle portion 42 is pulled upward, the lower end of the material ejecting portion 43 can rotate to the lower side of the bottom of the magnet 50.

[0018] Preferably, the upper end of the reset spring 60 is fixed to the left side wall of the rotary vertical rod 30 above the rotary mounting hole 31, and the lower end of the reset spring 60 is fixed to the lower part of the left side wall of the blanking portion 43. The trigger portion 42 extends rightward and downward from the right end of the rotary connection portion 41.

[0019] Preferably, the upper end of the right side wall of the rotary vertical rod 30 is perpendicularly connected to the left end of the hand-held cross rod 10, and the lower end of the right side wall of the rotary vertical rod 30 is perpendicularly connected to the left end of the magnet mounting cross rod 20. The lower end of the rotary mounting hole 31 penetrates through the lower end of the rotary vertical rod 30.

[0020] Preferably, the laser cutting machine material taking device 100 further includes a hand-held vertical rod 70. The upper end of the hand-held vertical rod 70 is fixedly connected to the right end of the hand-held cross rod 10, and the lower end of the hand-held vertical rod 70 is fixedly connected to the right end of the magnet mounting cross rod 30.
