Description

Technical Field

[0001] The utility model relates to the field of laser cutting machines, in particular to a follow-up encircling laser cutting machine. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt and vaporize rapidly, while a high-speed airflow coaxial with the beam blows away the molten material, thereby cutting the workpiece. The laser used for cutting is generally a level 3 or 4 laser, which will produce strong light during processing, and will also produce different degrees of scattering due to different processed materials. If the operator misjudges the processing position or is exposed to scattered light, it will cause damage to the eyes for a long time and produce a stinging sensation. In addition, a large amount of slag and smoke will be generated during the cutting process. Under the action of the processing auxiliary gas, the smoke will spread around the equipment. These fumes contain a large number of chemical components, which will also cause certain harm to the human respiratory system.

[0003] At present, for the above-mentioned problem, a commonly used method is to directly set a set of dust suction equipment in the cutting machine body to suck away the smoke. However, the exhaust port of the dust suction equipment is often set below the processing table, at the position of the ground rails on both sides of the table, which is a certain distance away from the cutting position. Especially when the cutting position is located in the middle of the table, the exhaust dust removal effect is poor.

[0004] On the other hand, a large enclosure can be set outside the laser cutting machine to form a relatively closed space around the laser cutting machine, and an air purification system can be installed to purify the air inside the large enclosure, which can achieve a more thorough purification effect. However, laser cutting machines with large enclosures are often larger in size and have higher equipment costs. Summary of the invention

[0005] The utility model aims to solve the problems of large enclosure structure of current laser cutting machines being too large and costly, and provides a laser cutting machine with a follow-up enclosure.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a follow-up type enclosed laser cutting machine, including a bed, a crossbeam movably installed on the bed, an enclosed component fixedly installed on the crossbeam, the enclosed component encloses the top surface and the surrounding of the crossbeam, and the top of the enclosed component is connected to the exhaust gas purification box through an exhaust pipe. This solution installs an enclosed component on the crossbeam of the laser cutting machine, partially encloses the crossbeam and the laser head thereon, forms an enclosed space at the processing position, and guides the gas therein to the exhaust gas purification box through the exhaust pipe. At the same time, the enclosed component moves with the crossbeam, that is, the processing position. This solution ensures the wind dust removal effect while the laser cutting machine is smaller in size and has lower equipment cost.

[0007] Preferably, the enclosure assembly includes two end panels, which are respectively fixedly mounted at the two ends of the beam, and two middle panels are arranged between the two end panels. A set of opposite sides of the middle panels are respectively connected to the two end panels, and in the moving direction of the beam, the two end surfaces are respectively located at the front and rear sides of the beam, and an upper cover body is jointly installed on the top of the end panels and the middle panels.

[0008] Preferably, the upper cover body is in the shape of a cone that contracts upward, and the exhaust duct is connected to the top end of the upper cover body.

[0009] Preferably, at least one of the middle panels is provided with a window, in which a switch door is installed, so as to facilitate the inspection and maintenance of the beam and head components of the laser cutting machine.

[0010] Preferably, in the vertical direction, the lower end of the end panel extends below the table top of the bed.

[0011] Preferably, a barrier curtain is provided at the bottom of the middle panel to increase the coverage of the surrounding component and improve the sealing performance, while the barrier curtain can be deformed and will not scratch the workpiece.

[0012] Preferably, the exhaust duct includes a first duct, a collecting tank and a second duct, the collecting tank is fixedly arranged on the side of the bed, one end of the first duct is connected to the surrounding assembly, and the other end is connected to the collecting tank, and the end of the collecting tank is connected to the exhaust gas purification box through the second duct. The exhaust duct is divided into a part that moves with the surrounding assembly and a fixed part, the fixed part, the moving part is close to the cutting machine bed, and the fixed part is arranged on the ground and connected to the exhaust gas purification box, which can optimize the space layout in the workshop and reduce the space occupied by moving parts.

[0013] Preferably, the collecting groove is a U-shaped groove, a dust box is slidably mounted on the opening surface of the U-shaped groove, and bellows covers are provided between the two sides of the dust box and the two ends of the collecting groove, and the bellows covers cover the opening of the U-shaped groove. The first pipe is connected to the dust box. The dust box can be moved, and the first pipe does not need to be extended and retracted in a large range, thereby reducing the required length of the first pipe.

[0014] Preferably, the dust collection box is fixedly connected to the surrounding assembly or the crossbeam. The dust collection box moves with the crossbeam, which greatly reduces or eliminates the tension on the first pipeline.

[0015] Preferably, a first fan is provided at the connection between the enclosure component and the first pipeline, and / or a second fan is provided at the connection between the collection tank and the second pipeline.

[0016] It can be seen from the above technical scheme that the advantages of the utility model are that the laser cutting machine is equipped with a local enclosing component on the beam. The enclosing component moves with the beam and is kept in the processing position at any time, forming a relatively closed space at the processing position, and exhausting and purifying the space. Compared with the integral large enclosing components, the overall volume of the equipment is greatly reduced, and the equipment cost is reduced; the pipeline structure design and layout are reasonable, the pipeline is subjected to small tension, and the range of movement is small, which reduces the occupation of workshop space by dynamic components and further reduces the space required for equipment; at the same time, the equipment is easy to assemble and has good covering properties. It also has a switch door, which is convenient for maintenance of beams, machine heads and other components. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] like Figure 1As shown, a follow-up enclosed laser cutting machine includes a bed 1, on which a crossbeam is movably installed. The bed, the crossbeam and the driving structure between the two are all prior art and will not be described here. In this laser cutting machine, an enclosed assembly is fixedly installed on the crossbeam, and the enclosed assembly is enclosed on the top surface and the surrounding of the crossbeam. Specifically, the enclosed assembly includes two end panels 2 and two middle panels. The end panels 2 and the middle panels form a box structure that is through from top to bottom. The two end panels 2 are respectively fixedly installed at the two ends of the crossbeam, and a group of opposite sides of the middle panel are respectively connected to the edges of the two end panels 2 on the same side. In the moving direction of the crossbeam, the two middle panels are respectively located on the front and rear sides of the crossbeam, that is, the two end panels 2 and the two middle panels surround the four sides of the crossbeam. In the vertical direction, the lower end of the end panel 2 extends to the bottom of the table of the bed 1, and a curtain 5 is provided at the bottom of the middle panel. A hollow window is provided in the two end panels 2, and a switch door 4 is provided in the window. The switch door 4 can be opened to perform maintenance operations on the crossbeam and its upper machine head and other components.

[0024] The top of the two end panels 2 and the two middle panels are jointly mounted with an upper cover 3, which is a conical structure and contracts upwards. Figure 1 As shown, it is a quadrangular pyramid with a rectangular bottom surface. The four sides of the rectangle are fixedly connected to the top edges of the two end panels 2 and the two middle panels. An exhaust duct is connected to the top of the upper cover 3. Figure 2 The exhaust duct includes a first duct 6, a collecting trough 7 and a second duct 8. The collecting trough 7 is fixedly arranged on the side of the bed 1. The collecting trough 7 is a U-shaped trough. A dust box 9 is slidably installed on the opening surface of the U-shaped trough (for example, installed by a linear guide rail). An accordion cover 13 is provided between the two side surfaces of the dust box 9 and the two ends of the collecting trough 7. The accordion cover 13 covers the opening of the U-shaped trough. One end of the first duct 6 is connected to the conical top end of the upper cover body 3, and a first fan 10 is provided at the connection. The other end of the first duct is connected to the dust box 9; one end of the second duct 8 is connected to one end of the collecting trough 7 (the other end of the collecting trough is closed), and a second fan 11 is provided at the connection. The other end of the second duct 8 is connected to the exhaust gas purification box 12.

[0025] When the laser cutting machine of the utility model is working, the surrounding assembly moves with the crossbeam, and the laser processing position is located below the machine head on the crossbeam, that is, the surrounding assembly is located above the processing position at any time, and the cutting smoke is attracted to the exhaust gas purification box through the first and second fans. During this process, the dust collection box moves with the movement of the first pipe.

[0026] Furthermore, the dust box can be fixedly connected to the crossbeam or the surrounding component so that the dust box moves with the crossbeam, thereby eliminating the pulling force on the first pipe caused by dragging the dust box. Specifically, an extension plate can be added to the bottom of the end panel 2 close to the collecting trough side, and the extension plate can be fixedly connected to the dust box.

[0027] It can be seen from the above embodiments that the beneficial effect of the utility model lies in that the laser cutting machine is equipped with a local enclosing component on the crossbeam, and the enclosing component moves with the crossbeam and is kept in the processing position at any time, forming a relatively closed space at the processing position, and exhausting and purifying the space. Compared with the integral large enclosing components, the overall volume of the equipment is greatly reduced, and the equipment cost is reduced; the pipeline structure is reasonably designed and arranged, the pipeline is subjected to small tension and has a small range of motion, which reduces the occupation of workshop space by dynamic components and further reduces the space required for the equipment; at the same time, the equipment is easy to assemble and has good covering properties. It also has a switch door, which is convenient for inspection and maintenance of components such as crossbeams and machine heads.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
