Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting machine for fireproof partition treatment. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam. When laser cutting steel fireproof partition frames, the laser emitter emits a downward-facing laser beam to cut the flat frame steel. To prevent potential hazards from prolonged laser emitter operation and to effectively cool the emission port of the laser emitter during rest periods, the laser emitter needs to be replaced periodically. After replacement, the new laser emitter continues to emit a downward-facing laser beam to cut the frame steel. When the laser emitter is replaced, the laser beam illuminating the frame steel disappears, and laser cutting pauses. Subsequently, a new laser beam is generated, and the cutting of the frame steel continues. There is a temperature change on the cut surface of the frame steel, and the cut surface of the frame steel is not formed continuously, ultimately resulting in an uneven cut surface of the frame steel.

[0003] In existing technologies, two laser emitters can be used to irradiate the same point. After one laser beam disappears, the other laser emitter immediately emits a laser, which can avoid the gap problem of the laser disappearing and reappearing, and achieve the purpose of continuous laser cutting. However, this laser cutting method still has shortcomings. Although the laser irradiation point is the same, the laser beams emitted by the two laser emitters are in different directions, resulting in differences in the front and back of the cut on the frame steel. It is necessary to change the laser irradiation method to reduce this difference.

[0004] By dispersing the original laser beam into multiple low-energy laser beams, the problem of significant changes in temperature and direction after the disappearance of a single laser beam can be avoided. In other words, multiple laser beams are used to converge and irradiate the same cutting point. When multiple laser emitters are working, one laser emitter is taken out to rest in turn, while the remaining laser emitters work together. This reduces the impact of changes in a single variable on the whole and reduces the variation in the laser-cut surface on the frame steel. Summary of the Invention

[0005] The purpose of this invention is to provide a laser cutting machine for fireproof partition processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting machine for fireproof partition treatment, comprising a laser focusing head and a machine tool body for controlling the movement and power supply of the laser focusing head, wherein the laser focusing head comprises:

[0007] A pile tube installed on the machine tool body, with power supply wires installed inside the pile tube;

[0008] Multiple conical frames arranged in a fan shape are installed below the pile, and a laser emitter is fixed in each conical frame;

[0009] Each conical square frame is connected to a telescopic device on one side, and a row of arc-shaped sliding rods are distributed perpendicularly to the telescopic devices, as well as multiple arc-shaped springs sleeved on the arc-shaped sliding rods. The arc-shaped sliding rods support multiple telescopic devices arranged in an arc shape, and an arc-shaped spring is placed between two adjacent telescopic devices.

[0010] The air control system supplies air to all expansion joints. The air control system has two semi-arm devices driven at both ends, and a concave main frame for supporting the semi-arm devices. The end of the arc-shaped sliding rod is fixed on the concave main frame. The concave main frame supports the air control system and is fixed on the pile. After a conical square frame is separated from the fan-shaped arrangement, two semi-arm devices cooperate to clamp the remaining conical square frame to form a new fan-shaped arrangement. Multiple laser emitters in the new arrangement achieve cutting by emitting lasers that converge on the steel.

[0011] The telescopic device includes:

[0012] A translational plate fixed at one end to a conical square frame, a unit plate set at the other end of the translational plate, and a tension spring connecting the unit plate and the translational plate. The translational plate slides through the plate hole opened on the unit plate, and the arc-shaped slide rod slides through the arc-shaped hole opened on the unit plate. Both sides of the unit plate are in contact with arc-shaped springs.

[0013] The accompanying rigid tube is fixed to the unit plate, and a telescopic tube is slidably inserted into the accompanying rigid tube at one end. The other end of the telescopic tube is fixed to a plug set on the translation plate, and the plug is provided with a vent hole.

[0014] The pneumatic control integration includes an L-shaped pile plate fixed at one end to the concave main frame, a gas distribution pipe fixedly supported at the other end of the L-shaped pile plate, multiple stationary hard pipes fixedly connected to the gas distribution pipe, a hose fixedly connected at one end of each stationary hard pipe, a switch group for controlling the gas flow between the gas distribution pipe and the stationary hard pipe, and a central control frame with contact transmission on one side of the switch group. The end of the central control frame establishes a transmission with the semi-arm device, and the hose and the accompanying hard pipe are fixedly connected.

[0015] The switch assembly includes an integrated shaft supported on an L-shaped piling plate, a row of cam bodies fixed on the integrated shaft, an L-shaped door plate controlled by pushing on one side of each cam body, and a spring-loaded reset component for driving the L-shaped door plate to reset. One end of the L-shaped door plate with a reset tendency is close to the cam body, and the other end of the L-shaped door plate is slidably inserted into the plate groove set at the interface of the stationary hard pipe and the gas distribution pipe.

[0016] One end of the integrated shaft is movably sleeved in a through hole opened in an L-shaped pile plate. The cam body includes a cam and a horizontal bar vertically fixed at the tip of the cam. The tips of a row of cam bodies point in different directions and are evenly arranged in multiple directions.

[0017] The central control frame includes a horizontal frame column and a row of sub-columns vertically fixed on one side of the horizontal frame column. The sub-columns are provided with arc-shaped tips that pass through square holes opened on the L-shaped door panel. When the tip of the cam body fully lifts the L-shaped door panel, the horizontal bar on the cam body pushes the sub-columns on the central control frame.

[0018] The semi-arm device includes an extension group located at the end of the concave main frame, a rod frame connected to one end of the extension group, a transfer group that establishes a transmission with the central control frame, and a lifting frame that transmits between the transfer group and the extension group. Two rod frames that are close to each other cooperate to clamp multiple conical square frames arranged in an arc.

[0019] The adapter assembly includes a Z-shaped pile fixed on the concave main frame, a range extender shaft supported on the Z-shaped pile, and a range extender gear fixed at one end of the range extender shaft. The range extender shaft is movably sleeved in a through hole opened on the Z-shaped pile.

[0020] The lifting frame slides through the long rail square hole set on the Z-shaped pile, and the top of the lifting frame is equipped with a row of teeth to mesh with the range extender gear for transmission, and the end of the range extender shaft is equipped with a shaft gear to mesh with the rack set at the end of the central control frame for transmission.

[0021] The range extender assembly includes an ear plate fixed on the concave main frame, a lever shaft movably sleeved in a through hole on the ear plate, a swing body fixed at one end of the lever shaft, and an arc seat plate rack that drives on one side of the swing body. The arc seat plate rack and the rod frame are fixedly connected.

[0022] The swing pressure body is equipped with an arc-shaped rack that meshes with the arc seat plate rack for transmission. The arc seat plate rack slides through the arc plate hole opened at the end of the concave main frame. The end of the lever pressure shaft is equipped with a gear that meshes with a row of teeth at the end of the lifting frame for transmission.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The laser cutting point is moved on the frame steel to achieve cutting. This invention controls multiple weak laser beams to converge and irradiate one laser cutting point. When a single laser beam emitter is replaced, if one laser beam disappears, a new laser beam will immediately be generated and irradiate the laser cutting point. In this way, the energy destructive intensity of the convergence point of multiple laser beams remains unchanged.

[0025] 2. Compared with the problem that the resulting cut surface structure and texture are obviously different when two laser beams from different directions irradiate the cutting point in turn in the traditional technology, the laser beam convergence point in this invention faces downward. The replacement of a single laser beam has little impact on the main direction of the laser beam convergence point. Moreover, after the laser beam emitter is replaced, the multiple laser emitters that emit the laser beam re-converge, so the impact direction of the main body of the laser beam convergence point is more stable.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1 to 14 The present invention provides a technical solution: a laser cutting machine for fireproof partition treatment, comprising a laser focusing head 1, and a machine tool body 2 for controlling the movement and power supply of the laser focusing head 1, wherein the laser focusing head 1 comprises:

[0043] The pile tube 3 is installed on the machine tool body 2, and power supply wires are laid inside the pile tube 3;

[0044] Multiple conical square frames 4 arranged in a fan shape are set below the pile tube 3, and a laser emitter 5 is fixed in each conical square frame 4.

[0045] Each conical square frame 4 is connected to a telescopic device 6 on one side, and a row of arc-shaped sliding rods 7 are distributed perpendicularly to the telescopic device 6, and multiple arc-shaped springs 8 are sleeved on the arc-shaped sliding rods 7. The arc-shaped sliding rods 7 support multiple arc-shaped telescopic devices 6, and an arc-shaped spring 8 is placed between two adjacent telescopic devices 6.

[0046] The pneumatic control integration 9 supplies air to all expansion joints 6. The pneumatic control integration 9 drives the semi-arm device 10 at both ends, and the concave main frame 11 supports the semi-arm device 10. The end of the arc-shaped slide rod 7 is fixed on the concave main frame 11. The concave main frame 11 supports the pneumatic control integration 9 and is fixed on the pile cylinder 3. After a conical square frame 4 is separated from the fan-shaped arrangement, two semi-arm devices 10 cooperate to clamp the remaining conical square frame 4 to form a new fan-shaped arrangement. The multiple laser emitters 5 in the new arrangement achieve cutting by emitting lasers that converge on the steel.

[0047] The main workflow of this invention is as follows: (Refer to...) Figure 6 In a series of conical frames 4 arranged in an arc, one frame 4 will be removed from the arrangement. The remaining frames 4 will then be reassembled into a new fan-shaped queue. Multiple laser emitters 5 in this new queue will collectively emit lasers to converge on a single cutting point, similar to the principle of laser focusing. The laser emitters 5 in the removed frame 4 will not emit lasers. At predetermined intervals, the removed frame 4 will return to the queue, and a new frame 4 will be selected for the next removal, while the previous frame 4 returns. Upon joining the queue, the laser emitter 5 in the conical frame 4 emits a laser, while the laser emitter 5 in the next conical frame 4 preparing to leave the queue stops emitting a laser. This connection ensures that the overall cutting laser energy remains constant. After the next conical frame 4 has completely left the queue, the remaining conical frames 4 converge again to form a new fan-shaped queue, completing one work cycle. When multiple laser beams converge, changes in a single laser beam have little impact on the overall laser beam irradiation direction. Thus, when the laser beam composed of multiple weak laser beams converges to cut the steel frame, the resulting steel cut surface is smoother.

[0048] refer to Figure 7 Understood, the telescoping device 6 includes:

[0049] A translational plate 16 is fixed at one end to a conical square frame 4, a unit plate 15 is provided at the other end of the translational plate 16, and a tension spring 14 is connected between the unit plate 15 and the translational plate 16. The translational plate 16 slides through the plate hole opened on the unit plate 15, the arc-shaped slide rod 7 slides through the arc-shaped hole opened on the unit plate 15, and both sides of the unit plate 15 are in contact with arc-shaped springs 8.

[0050] A rigid tube 13 is fixed to the unit plate 15, and a telescopic tube 12 is slidably inserted into the rigid tube 13 at one end. The other end of the telescopic tube 12 is fixed to a plug provided on the translation plate 16, and the plug has a vent hole. Air is injected into the rigid tube 13, and the air pressure is applied to the translation plate 16. Figure 7 The translation plate 16 will gradually slide to the left. If the air injection stops, the vent hole on the plug will slowly release the air, so the tension spring 14 will pull the translation plate 16, and the translation plate 16 will slide back to the right.

[0051] refer to Figure 8The pneumatic control integration 9 includes an L-shaped piling plate 22 with one end fixed to the concave main frame 11, a gas distribution pipe 21 fixedly supported at the other end of the L-shaped piling plate 22, a plurality of stationary hard pipes 18 fixedly connected to the gas distribution pipe 21, a hose 19 fixedly connected to one end of each stationary hard pipe 18, a switch group 20 for controlling the gas flow between the gas distribution pipe 21 and the stationary hard pipes 18, and a central control frame 17 with contact transmission on one side of the switch group 20. The end of the central control frame 17 establishes transmission with the semi-arm device 10, and the hose 19 and the accompanying hard pipe 13 are fixedly connected.

[0052] refer to Figure 10 Understandably, the switch assembly 20 includes an integrated shaft 25 supported on an L-shaped piling plate 22, a row of cam bodies 26 fixed on the integrated shaft 25, an L-shaped door plate 24 with push control on one side of each cam body 26, and a spring-loaded reset member 23 for driving the L-shaped door plate 24 to reset. One end of the L-shaped door plate 24 with a reset tendency is close to the cam body 26, and the other end of the L-shaped door plate 24 is slidably inserted into the plate groove provided at the interface between the stationary hard tube 18 and the air distribution tube 21.

[0053] One end of the integrated shaft 25 is movably sleeved in the through hole opened on the L-shaped pile plate 22. The cam body 26 includes a cam and a horizontal bar that is vertically fixed at the tip of the cam. The tips of a row of cam bodies 26 point in different directions and are evenly arranged in multiple directions.

[0054] refer to Figure 10 Understandably, the central control frame 17 includes a horizontal frame column and a row of sub-columns vertically fixed on one side of the horizontal frame column. The sub-columns are provided with arc-shaped tips that pass through the square holes opened on the L-shaped door panel 24. When the tip of the cam body 26 fully lifts the L-shaped door panel 24, the horizontal bar on the cam body 26 pushes the sub-columns on the central control frame 17.

[0055] One end of the gas distribution pipe 21 is externally connected to a gas supply mechanism in the prior art, and one end of the integrated shaft 25 is externally connected to a drive mechanism in the prior art. By controlling the rotation of the integrated shaft 25, a stationary rigid pipe 18 and a gas distribution pipe 21 are selected for gas supply. Specifically, a cam body 26 is controlled to push the tip of an L-shaped door panel 24, which will produce... Figure 10In the middle state, the L-shaped door panel 24 slides to the right, and the left end of the L-shaped door panel 24 leaves the interface between the stationary hard pipe 18 and the air distribution pipe 21. Then, the airflow in the air distribution pipe 21 is injected into the stationary hard pipe 18. When the cam body 26 pushes the L-shaped door panel 24 to the maximum extent, the cross bar on the cam body 26 presses against the column of the control frame 17. If the integrated shaft 25 continues to rotate, the L-shaped door panel 24 will lose the push of the tip of the cam body 26. The spring reset component 23 drives the L-shaped door panel 24, and the L-shaped door panel 24 gradually moves to the left to reset. The left end of the L-shaped door panel 24 will re-seal the interface channel between the stationary hard pipe 18 and the air distribution pipe 21. The spring reset component 23 is a prior art device, including a shaft fixed on one side of the air distribution pipe 21, a spring fixedly sleeved on the outside of the shaft, and a cylindrical gear fixedly sleeved on the outside of the spring. One end of the cylindrical gear is movably sleeved on the shaft of the spring reset component 23 through a fixed ring plate.

[0056] The semi-arm device 10 includes an extension group 30 disposed at the end of the concave main frame 11, a rod frame 29 connected to one end of the extension group 30, a transfer group 27 that establishes a transmission with the central control frame 17, and a lifting frame 28 that transmits between the transfer group 27 and the extension group 30. Two rod frames 29 that are close to each other cooperate to clamp multiple conical square frames 4 arranged in an arc.

[0057] The adapter assembly 27 includes a Z-shaped pile 31 fixed on the recessed main frame 11, a range extender shaft 33 supported on the Z-shaped pile 31, and a range extender gear 32 fixed at one end of the range extender shaft 33. The range extender shaft 33 is movably sleeved in a through hole opened on the Z-shaped pile 31.

[0058] The lifting frame 28 slides through the long rail square hole set on the Z-shaped pile 31, and the top of the lifting frame 28 is equipped with a row of teeth to mesh with the range extender gear 32 for transmission, and the end of the range extender shaft 33 is equipped with a shaft gear to mesh with the rack set at the end of the central control frame 17 for transmission.

[0059] The range extender 30 includes an ear plate 36 fixed on the concave main frame 11, a lever shaft 34 movably sleeved in a through hole on the ear plate 36, a swing body 35 fixed at one end of the lever shaft 34, and an arc seat plate rack 37 that drives on one side of the swing body 35. The arc seat plate rack 37 and the rod frame 29 are fixedly connected.

[0060] The swing pressure body 35 is equipped with an arc-shaped rack to mesh with the arc seat plate rack 37 for transmission. The arc seat plate rack 37 slides through the arc plate hole opened at the end of the concave main frame 11. The end of the lever pressure shaft 34 is equipped with a gear to mesh with a row of teeth set at the end of the lifting frame 28 for transmission.

[0061] As previously mentioned, by controlling the rotation of the integrated shaft 25, a stationary rigid tube 18 is selected for ventilation. In this way, the airflow in the air distribution tube 21 is injected into the stationary rigid tube 18, and then injected into the accompanying rigid tube 13 through the hose 19. The air pressure is then applied to the designated expansion joint 6. As previously mentioned, the ventilated expansion joint 6 will drive the corresponding conical square frame 4 to leave the fan-shaped queue. As a result, the laser emitter 5 in the conical square frame 4 will leave the fan-shaped queue. The remaining conical square frames 4 will be clamped by the rods 29 that converge on both sides. The remaining conical square frames 4 will then converge again to form a new fan-shaped queue. Here, one conical square frame 4 leaves the queue, and the remaining conical square frames 4 converge. The main body of the conical square frame 4 occupies a fixed angle, and the swing angle of the converging conical square frame 4 is half of its own occupied angle.

[0062] The driving process of the rod frame 29 is as follows: after the column on the central control frame 17 is pushed, the end of the moving central control frame 17 drives the extension shaft 33, and then drives the lifting frame 28 through the extension gear 32. The lifting frame 28 descends to drive the lever pressure shaft 34 to rotate. Then the swing pressure body 35 swings to drive the arc seat plate rack 37 to slide, which in turn causes the rod frame 29 to be driven. The two rod frames 29 cooperate to support the multiple conical square frames 4 arranged in a fan shape.

[0063] To further explain the previous paragraph, one conical frame 4 detaches from the fan-shaped formation, and the remaining conical frames 4 regroup to form a new fan-shaped formation. The conical frames 4, the translation plate 16, and the unit plates 15 swing synchronously. Thus, the regrouping process of the remaining conical frames 4 is accompanied by the movement of the unit plates 15 on the arc-shaped slide bar 7, causing the arc-shaped springs 8 on both sides to deform. The multiple arc-shaped springs 8 distributed on the arc-shaped slide bar 7 are used to push the unit plates 15 to reset, that is, the two rods 29 move away from each other. The regrouped conical frames 4 automatically separate under the push of the arc-shaped springs 8, leaving space for the conical frames 4 that are about to return to the formation. Because there is no external pressure, that is, after the two rods 29 separate, the row of arc-shaped springs 8 on the arc-shaped slide bar 7 applies elastic force at the same time, which controls the row of unit plates 15 on the arc-shaped slide bar 7 to be evenly distributed, thus corresponding to the multiple conical frames 4 arranged in an even arc shape. Each conical frame 4 has its own position to enter and exit the fan-shaped formation.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
