[0002] A laser cutting machine is a high-precision and high-efficiency cutting device, mainly used for cutting metal and non-metal materials. Its working principle is that a high-power density laser beam is emitted by a laser, irradiated on the surface of a workpiece, so that the workpiece reaches the melting point or boiling point, and at the same time, a high-pressure gas blows away the melted or vaporized metal, thereby achieving the purpose of cutting.

[0003] When the laser cutting machine starts to work, heat will be generated. The workpiece is cut through the melting point or boiling point, so the workpiece will be very hot during cutting. After the processing is completed, the operator needs to manually pick up and place the workpiece, which may scald the operator during the picking up and placing process, posing a great safety hazard to the operator.

Specific embodiments

[0022] As Figures 1-5 shown, the present utility model provides a technical solution: a protective structure for the cutting area of a high - power laser cutting machine, including a base 1. The top of the base 1 is slidably connected with a left - right moving frame 2, which facilitates the left - right movement of the laser head 4. The top of the left - right moving frame 2 is slidably installed with a front - back moving frame 3, which facilitates the front - back movement of the laser head 4. The left side of the front - back moving frame 3 is fixedly connected with a laser head 4, which can cut workpieces. The right side of the base 1 is fixedly installed with a motor 5, which can drive the threaded rod 6 to rotate. The output end of the motor 5 is fixedly connected with a threaded rod 6, which can make the left - right moving frame 2 move left and right. The threaded rod 6 penetrates through the sliding part of the left - right moving frame 2. The left side of the base 1 is provided with a cooling mechanism 7, which can cool the workpiece during processing. The top of the base 1 is provided with a lifting device 8, which facilitates the taking out of the workpiece after processing.

[0023] Specifically, the cooling mechanism 7 includes: a fixing plate 71, a rotating shaft 72, a spray head 73, a water pipe 74, a telescopic rod 75, a slider 76, a fixing block 77, a moving spring 78, a moving rod 79, and a convex block 710. The bottom of the front-back moving frame 3 is fixedly installed with a fixing plate 71, which can install the rotating shaft 72 and enable the rotating shaft 72 to rotate in the fixing plate 71. The front of the fixing plate 71 is rotatably connected to the rotating shaft 72, which can drive the spray head 73 to swing. The outer wall of the rotating shaft 72 is fixedly connected to the spray head 73, which can spray water on the workpiece for cooling. A water pipe 74 is fixedly installed on the front of the spray head 73, which can supply water to the spray head 73. A telescopic rod 75 is fixedly installed at the cam position on the front of the rotating shaft 72, which can swing the rotating shaft 72 under the drive of the slider 76. The back of the telescopic rod 75 is fixedly installed with a slider 76, which can drive the telescopic rod 75 to move up and down. The back of the slider 76 is slidably connected to a fixing block 77, which is convenient for fixing the position of the slider 76 and also convenient for sliding. The back of the fixing block 77 is fixedly connected to the right side of the left-right moving frame 2. The top of the sliding groove of the fixing block 77 is fixedly installed with a moving spring 78, which can reset the slider 76 when the moving rod 79 is not squeezed. One end of the moving spring 78 away from the top of the fixing block 77 is fixedly connected to the top of the slider 76. The bottom of the slider 76 is fixedly installed with a moving rod 79, which can drive the slider 76 to move up and down. The top of the base 1 is fixedly installed with convex blocks 710, which can drive the slider 76 to move upward when the moving rod 79 is squeezed during the moving process. The convex blocks 710 are linearly arrayed on the top of the base 1, which can increase the number of swings of the spray head 73 and make the spraying more uniform.

[0024] Specifically, the lifting device 8 includes: a sliding groove 81, a reset spring 82, a connecting rod 83, and a support rod 84. The bottom of the left-right moving frame 2 where it slides is provided with a sliding groove 81, which is convenient for the connecting rod 83 to be hidden inside without interfering with the movement of the left-right moving frame 2. The bottom of the sliding groove 81 is fixedly installed with a reset spring 82, which can drive the connecting rod 83 to reset. One end of the reset spring 82 away from the sliding groove 81 is fixedly connected to the connecting rod 83, which can drive the support rod 84 to move upward during reset. The reset spring 82 and the connecting rod 83 are provided in two groups and are symmetrically distributed on the front and back sides of the base 1 with respect to the central axis of symmetry of the front of the base 1, which can make the workpiece rise more evenly. The left side of the connecting rod 83 is fixedly connected to the support rod 84, which can make the convex column at the top hold the workpiece above the sharp object.

[0025] Working principle: When the laser cutting machine starts to work, starting the motor 5 drives the threaded rod 6 to rotate, which can make the left and right moving frame 2 move left and right, and at the same time drive the moving rod 79 to move. During the movement, the bottom of the moving rod 79 will be squeezed by the convex block 710, causing the moving rod 79 to rise, driving the slider 76 to rise in the sliding groove of the fixed block 77, simultaneously driving the moving spring 78 to compress, and also driving the telescopic rod 75 to rise. When the telescopic rod 75 rises, it drives the rotating shaft 72 to rotate. When leaving the convex block 710, the reset of the moving spring 78 will drive the moving rod 79 and the telescopic rod 75 to move downward. At the same time, the nozzle 73 will swing left and right. By connecting the outer end of the water pipe 74 to the water pool, water can be supplied to the nozzle 73 through the water pipe 74, so that the water is evenly sprinkled on the workpiece, preventing the temperature from being too high during laser cutting and causing burns.

[0026] After the workpiece is processed, it moves to the initial position through the left and right moving frame 2. The bottom of the left and right moving frame 2 will leave the connecting rod 83. At this time, the reset spring 82 will drive the connecting rod 83 to rise, and at the same time drive the support rod 84 to rise. The convex column on the support rod 84 will also rise accordingly, and the convex column will drive the workpiece to rise. When the left and right moving frame 2 is working, the left and right moving frame 2 will squeeze the connecting rod 83, causing the connecting rod 83 to compress the reset spring 82 into the sliding groove 81, preventing the operator from being stabbed by the sharp objects on the surface of the base 1 when manually taking the workpiece, and bringing physical harm to the operator.

[0027] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
