Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, and specifically to a dust removal system for laser tube cutting machines. Background Technology

[0002] Laser tube cutting machines are highly efficient devices that use high-energy laser beams to cut metal tubes, and are widely used in automobile manufacturing, aerospace, and other fields. During the cutting process, a large amount of smoke, high-temperature molten particles, and small amounts of harmful gases are generated. If these hazards are not promptly eliminated, the following problems will occur: environmental pollution and occupational health risks, decreased equipment performance, and reduced product quality.

[0003] Traditional dust removal systems mostly use fixed negative pressure dust hoods, which can only cover the area near the cutting point. They have low efficiency in capturing all-around dust generated during pipe rotation cutting, especially from the inner wall of the pipe, the cutting end face, and splash particles, resulting in a large amount of dust escaping into the workshop. This invention designs a dust removal system for currently used laser pipe cutting machines, meeting the need for efficient removal of suspended dust, slag, and residues on the inner wall of the pipe. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a dust removal system for laser tube cutting machines, solving the problem of efficiently removing smoke, debris, and residues generated during tube cutting.

[0005] This utility model is achieved through the following technical solution:

[0006] A dust removal system for a laser tube cutting machine includes a dust collector, a slag removal mechanism, and a fixed dust suction hood. The fixed dust suction hood is located around the laser cutting head and its bottom side is connected to the dust collector. A front chuck and a rear chuck are used to clamp the tube to be cut. An air blowing port is added to the tail end of the rear chuck. A part of the slag removal mechanism can be extended into the tube to be cut.

[0007] Preferably, the slag removal mechanism includes a frame a, a linear bearing b, a cylinder c, a slag removal pipe d, and a vertical support plate f. The cylinder c is horizontally fixed to the top of the frame a. The slag removal pipe d is sleeved in the linear bearing b. The telescopic end of the cylinder c is horizontally fixed to the vertical support plate e. One end of the slag removal pipe d is provided with a receiving hole. The bottom of the frame a is provided with the linear bearing b. The other end of the slag removal pipe d, after being horizontally inserted through the linear bearing b, is radially and vertically fixed to the vertical support plate f, and an air intake e is provided at the end of this end.

[0008] Preferably, the vertical support plate e is also provided with an adjusting screw horizontally, the head of which is fixed to the vertical support plate e, and the other end of which can abut against the side wall of the frame a.

[0009] Preferably, after the other end of the slag removal pipe d is horizontally inserted through the linear bearing b, a vertical support plate f is vertically fixed radially through the mounting flange.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Figure 1-2A dust removal system for a laser tube cutting machine is shown, including a dust collector, a slag removal mechanism 1, and a fixed dust suction hood 3. The fixed dust suction hood 3 is located around the laser cutting head 2, and its bottom side is connected to the dust collector, which is used to adsorb suspended dust and some molten slag in the cutting area. A front chuck 4 and a rear chuck 6 are used to hold the tube 5 to be cut. An air outlet 7 is added to the tail end of the rear chuck 6, which can be connected to high-pressure air. A part of the slag removal mechanism 1 can extend into the tube 5 to be cut. By combining the fixed dust suction hood 3, positive pressure air blowing from the air outlet 7, negative pressure collection by the dust collector, and slag removal from the inner wall of the tube, the fixed dust suction hood 3 adsorbs suspended dust, the positive pressure air blowing unit removes high-temperature molten slag, and the negative pressure collection unit collects molten slag and debris inside the tube, a highly efficient cleaning process of "dust-molten slag-debris" is achieved.

[0019] Preferably, the slag removal mechanism 1 includes a frame a, a linear bearing b, a cylinder c, a slag removal pipe d, and a vertical support plate f. The cylinder c is horizontally fixed to the top of the frame a, the slag removal pipe d is sleeved in the linear bearing b, the telescopic end of the cylinder c is horizontally fixed to the vertical support plate e, one end of the slag removal pipe d has a receiving hole 9, the bottom of the frame a has a linear bearing b, and the other end of the slag removal pipe d, after being horizontally inserted through the linear bearing b, is radially and vertically fixed to the vertical support plate f, and a suction port e is constructed at the end of this end. A "blow-suction" airflow circuit is formed by the fixed dust suction hood 3 and the slag removal pipe d, which can be extended into the pipe 5 to be cut, to draw smoke and slag into the high negative pressure dust collector. The negative pressure is used to adsorb the slag and smoke blown into the cutting pipe 5 during laser cutting through the suction port e and the receiving hole 9 on the upper side of the slag removal pipe d, preventing the slag and smoke from adsorbing on the inner wall of the cutting pipe 5. Cylinder c is fixed on frame a to control the slag removal pipe d to reciprocate through linear bearing b.

[0020] An adjusting screw 10 is also horizontally mounted on the vertical support plate e, with its head fixed to the vertical support plate e and its other end abutting against the side wall of the frame a. When the telescopic end of the cylinder c retracts (e.g.) Figure 2 (That is, the slag removal pipe d is moved to the right in the figure), and the end of the adjusting screw 10 will gradually abut against the side wall of the frame a. The displacement of the slag removal pipe d can be adjusted by setting the length of the adjusting screw 10.

[0021] The other end of the slag removal pipe d is horizontally inserted through the linear bearing b, and then radially fixed to a vertical support plate f via the mounting flange 8. The mounting flange 8 facilitates disassembly and installation, and allows for regular replacement of the slag removal pipe d.

[0022] The working principle of this utility model:

[0023] Positive pressure blows air through the air outlet 7, and negative pressure is collected by the dust collector: the negative pressure is used to adsorb the molten slag and dust blown into the cutting pipe 5 during laser cutting through the suction port e and the collection hole 9 on the upper side of the slag removal pipe d, so as to avoid the molten slag and dust adsorbing on the inner wall of the cutting pipe 5.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
