[0004] When the above device is in use, the existing device can well drive the position change of the baffle through the motor by using the protective cover and the baffle, and under the action of the protective cover, the safety of the staff can be well guaranteed. However, there can be a better optimization scheme in the design of the protective cover. For example, the protective cover can be used to protect against sputtered sparks and weaken the dazzling glare to avoid harm to the human body and eyes. Moreover, a large amount of waste gas will be generated during flame cutting, which causes harm to the human body, and an effective method is needed to control the waste gas. Therefore, a clamping type flame numerical control cutting machine that solves the above problems is needed. Content of the Utility Model

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 5, A clamping type flame numerical control cutting machine, including a processing frame 1. A side wall 2 is installed in the inner cavity of the processing frame 1. A workpiece 3 is placed on the inner wall of the side wall 2. A water storage tank 4 is provided at the bottom of the workpiece 3. A front and rear brake rod 5 is sleeved on the top of the side wall 2. A chute 6 is opened in the inner wall of the front and rear brake rod 5. A brake 7 is sleeved in the inner cavity of the chute 6. A sliding disk 8 is fixedly connected to the outer wall of the brake 7. A lifter 9 is sleeved on the inner wall of the sliding disk 8. A flame cutter 10 is installed on the outer wall of the lifter 9. A cutting port 11 is provided at the bottom of the flame cutter 10. An installation piece 12 is sleeved on the outer wall of the flame cutter 10. An extrusion structure 13 is connected to the inner wall of the installation piece 12. A gasket 14 is fixedly connected to the bottom of the extrusion structure 13. A reset device 15 is connected to the outer wall of the extrusion structure 13. One end of the reset device 15 away from the installation piece 12 is connected to a protective cover 16. An air extraction head 17 is fixedly installed on the outer wall of the installation piece 12.

[0023] In a preferred embodiment, a water storage tank 4 is formed at the position between the processing frame 1 and the workpiece 3, and the inner cavity of the water storage tank 4 is filled with cooling water. By forming the water storage tank 4 at the position between the processing frame 1 and the workpiece 3 on the device, a water storage tank 4 is formed at the position between the processing frame 1 and the workpiece 3 on the device, and a large amount of water is filled in the inner cavity of the water storage tank 4. When flame cutting is performed at the cutting port 11, part of the flame passing through the workpiece 3 during the cutting process impacts into the water, and then the water is used to cool the cutting flame.

[0024] In a preferred embodiment, the front and rear brake rod 5 moves back and forth along the outer wall of the side wall 2, and the brake 7 moves left and right along the inner wall of the chute 6. By moving the front and rear brake rod 5 back and forth along the outer wall of the side wall 2 on the device, when the cutting port 11 on the device needs to move, the front and rear brake rod 5 is used for reciprocating back and forth movement, and the brake 7 is used to move left and right along the chute 6, so that the cutting port 11 on the device reaches the predetermined position before the cutting work, and then the cutting is completed.

[0025] In a preferred embodiment, the flame cutter 10 is connected to the sliding disk 8 through the lifter 9, and the lifter 9 moves up and down along the inner wall of the sliding disk 8. By connecting the flame cutter 10 to the sliding disk 8 through the lifter 9 on the device, when the cutting port 11 on the device needs to descend to be close to the surface of the workpiece 3, the lifter 9 is used to drive the flame cutter 10 and the cutting port 11 to move up and down along the inner wall of the sliding disk 8, so as to complete the lifting of the height of the cutting port 11, and then complete the lifting work of the cutting port 11 during and after cutting.

[0026] In a preferred embodiment, the extrusion structure 13 has the same structure as the reset device 15, and there is a telescopic sleeve rod in the middle part, and a spring is wrapped around the outer wall. Since the extrusion structure 13 and the reset device 15 on the device have the same structure, when the extrusion structure 13 on the device contacts the outer wall of the workpiece 3 through the gasket 14, the gasket 14 transmits the extrusion force to the extrusion structure 13, causing the spring on the outer wall of the extrusion structure 13 to contract and the telescopic sleeve rod to contract. Moreover, the inner cavities of the extrusion structure 13 and the reset device 15 are connected, and the air in the inner cavity pushes the reset device 15 to perform an elongation movement, and the spring on the outer wall of the reset device 15 is stretched. Thus, when the extrusion structure 13 on the device is under pressure, the reset device 15 is pushed, and the prestress of the spring on the outer wall of the extrusion structure 13 is higher than that of the spring on the outer wall of the reset device 15. Therefore, when the pressure on the extrusion structure 13 disappears, the extrusion structure 13 drives the reset device 15 to reset.

[0027] In a preferred embodiment, the opening of the air extraction head 17 faces downward and is close to the cutting opening 11, and a trachea is connected to the top of the air extraction head 17. Since the opening of the air extraction head 17 on the device faces downward and is close to the cutting opening 11, the air extraction head 17 on the device collects waste gas at a position close to the cutting opening 11, and an external air extraction device is connected to the trachea at the top of the air extraction head 17. Thus, the air extraction head 17 on the device absorbs waste gas at a position close to the cutting opening 11, thereby avoiding a large amount of waste gas generated during the cutting process of the device from being discharged into the air.

[0028] Working principle: First, through the coordinated use of the gasket 14, the extrusion structure 13, the reset device 15, and the protective cover 16 on the device, when the cutting opening 11 on the device descends, the gasket 14 on the device will first contact the surface of the workpiece 3, and under the action of the extrusion force, compress the length of the extrusion structure 13. And when the inner cavities of the extrusion structure 13 and the reset device 15 are connected, the air flow pressure in the inner cavity pushes the reset device 15 to move a certain position, so that the protective covers 16 on both sides of the cutting opening 11 move closer to the middle and block the cutting opening 11. Thus, during the flame cutting process of the cutting opening 11, the splashing of sparks is avoided, which may cause harm to the human body, and at the same time, the harmful glare of the flame cutting is weakened by the protective cover 16 to reduce the harm to the human eye. Then, through the coordinated use of the air extraction head 17 and the cutting opening 11 on the device, the air extraction head 17 on the device collects waste gas at a position close to the cutting opening 11, and an external air extraction device is connected to the trachea at the top of the air extraction head 17. Thus, the air extraction head 17 on the device absorbs waste gas at a position close to the cutting opening 11, thereby avoiding a large amount of waste gas generated during the flame cutting process of the device from being discharged into the air and preventing the waste gas from being inhaled by the staff and causing harm to the human body.
