Description

Technical Field

[0001] The invention relates to the field of laser cutting machines, and in particular to a water cooling device and a water cooling method for a laser cutting machine. Background Art

[0002] The laser cutting machine uses a high-power laser beam focused by the optical path system from the laser emitted from the laser to irradiate the surface of the workpiece, so that the workpiece reaches the melting point or boiling point, and gradually forms a slit on the workpiece, thereby achieving the purpose of cutting. The laser cutting process uses an invisible light beam to replace the traditional mechanical knife. It has many advantages such as high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. However, the laser cutting machine will generate high heat during use. The laser cutting machine is in a high temperature state for a long time, and the heat dissipation of the laser cutting head is not timely, which may cause damage to parts.

[0003] The Chinese patent with announcement number CN219131169 U provides a cooling device for a laser cutting machine. The pumping mechanism pumps the cold water in the water cooling box into the water storage chamber in the shell of the laser cutting machine. The cold water in the water storage chamber physically cools the laser generator, so that the cold water in the water storage chamber enters the ring pipe through two support pipes. At the same time, three atomizing nozzles atomize the cold water, and then cool the laser cutting head and the plate cutting position.

[0004] In summary, the above structure requires a large amount of water resources to cool it during actual use, and the cooled water is directly discharged. This cooling method will cause a waste of water resources, and the ring pipe is fixed at the laser generator. During the water cooling process, the water cooling effect at some positions of the outer wall of the laser generator may be poor, which will affect the overall working efficiency of the laser generator. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a water cooling device and a water cooling method for a laser cutting machine, so as to solve the technical problem that the water source after cooling is directly discharged, which will cause waste of water resources and may lead to poor water cooling effect at some positions of the outer wall of the laser generator during the water cooling process.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water cooling device for a laser cutting machine, comprising a cutting table, a driving frame and a shell, a laser generator is installed in the shell, a first tooth block is arranged on one side of the driving frame, and a fixed gear meshing with the first tooth block is rotatably arranged in the shell, a reciprocating screw matched with the fixed gear is rotatably arranged in the shell, and a cooling plate matched with the reciprocating screw is slidably arranged on the outer wall of the laser generator, a second tooth block is arranged on the inner wall of the shell, and a driving gear matched with the second tooth block is rotatably connected at the cooling plate, one end of the driving gear penetrates into the cooling plate and is connected to a worm, and a worm wheel is meshed at one side of the worm, and an array of atomizing nozzles are evenly arranged on the inner wall of the worm wheel, a fixed filter plate is installed in the shell, and a piston plate matched with the cooling plate is slidably arranged at the bottom of the fixed filter plate, a cooling water tank is arranged on one side of the driving frame, and a water inlet pipe and a water return pipe are respectively connected between the cooling water tank and the shell.

[0007] By adopting the above technical scheme, the reciprocating screw is rotated by the action of the transmission mechanism, and the cooperation of the worm and the worm wheel is used to drive the atomizing nozzle to rotate on the inner side of the cooling plate. When the cooling plate slides downward, the vertical rod is squeezed, and the coolant accumulated at the bottom of the shell is squeezed into the return pipe, so that the cooled coolant is recovered for the second time. At the same time, the coolant is gathered at the bottom of the shell during the subsequent resetting process, so that the cooled coolant can cool the bottom end of the laser generator for the second time.

[0008] The present invention is further configured such that an annular flow channel is disposed on the outer wall of the shell, and the bottom of the annular flow channel is concavely configured.

[0009] By adopting the above technical solution, the coolant sprayed through the atomizing nozzle will accumulate in the annular flow channel. At this time, the accumulated coolant will flow to the bottom through the annular flow channel under the action of its own gravity. In this process, the flow path of part of the coolant on the outer wall of the shell is extended, and the cooling time of the coolant on the outer wall of the shell is also extended, thereby further improving the utilization rate of the coolant.

[0010] The present invention is further configured such that a transmission mechanism is connected to the top of the fixed gear, and the other end of the transmission mechanism is connected to a reciprocating screw.

[0011] By adopting the above technical solution, when the fixed gear rotates through the first tooth block, the transmission mechanism at the top will be driven to rotate, thereby driving the reciprocating screw at the other end of the transmission mechanism to follow and rotate.

[0012] The present invention is further configured such that a screw sleeve is slidably provided on the outer wall of the reciprocating screw, and one side of the screw sleeve is connected to a cooling plate.

[0013] By adopting the above technical solution, during the rotation of the reciprocating screw, the screw sleeve is driven to slide back and forth on the outer wall of the reciprocating screw, thereby driving the cooling plate to slide and cool on the outer wall of the laser generator.

[0014] The present invention is further configured such that the transmission mechanism includes a driving disk, a transmission belt and a driven disk, the driving disk and the driven disk are connected by a transmission belt, one end of the fixed gear is connected to the driving disk, and the other end of the driven disk is connected to the reciprocating screw rod, and the diameter of the driving disk in the transmission mechanism is larger than the diameter of the driven disk.

[0015] By adopting the above technical solution, the active disk will be driven to rotate during the rotation of the fixed gear, and the driven disk will drive the reciprocating screw to rotate under the action of the transmission belt. Since the diameter of the active disk in the transmission mechanism is larger than the diameter of the driven disk, the driven disk will drive the reciprocating screw to rotate several times during the process of the active disk driving the fixed gear to rotate several circles, thereby realizing that the cooling plate can slide back and forth multiple times in the outer shell during the driving of the drive frame.

[0016] The present invention is further configured such that both ends of the piston plate are provided with clamping blocks, the top of the clamping block is connected with a vertical rod, and a compression spring is connected between the clamping block and the inner wall of the shell.

[0017] By adopting the above technical solution, the bottom vertical rod will be squeezed when the cooling plate slides downward. At this time, the piston plate is driven downward by the action of the vertical rod. At the same time, the compression spring itself is in a stretched state. When the cooling plate is reset subsequently, the piston plate follows the reset slide under the reset action of the compression spring.

[0018] The present invention is further configured such that one end of the water inlet pipe passes through the shell and is connected to a branch pipe, and the number of the branch pipes corresponds to the atomizing nozzle, and the other end of the branch pipe passes through the cooling plate and is connected to the atomizing nozzle.

[0019] By adopting the above technical solution, the coolant in the cooling water tank is discharged into the branch pipe through the water inlet pipe, and then atomized and sprayed out through the atomizing nozzle.

[0020] The present invention is further configured such that a rotating groove is provided on the top of the cooling plate for the branch pipe to rotate following the worm gear.

[0021] By adopting the above technical solution, when the worm gear drives the atomizing nozzle to rotate, the rotating groove on the cooling plate facilitates the branch pipe to rotate together, and during the rotation process, the branch pipe can rotate orderly with the connection with the water inlet pipe.

[0022] The present invention is further configured such that a water inlet check valve and a water discharge check valve are respectively provided on the piston plate and the water return pipe.

[0023] By adopting the above technical solution, under normal conditions, the coolant will flow to the piston plate after passing through the fixed filter plate. The gravity of the coolant itself will cause the water inlet check valve to open and the water discharge check valve to close. At this time, the coolant will accumulate at the bottom of the shell. Subsequently, as the piston plate slides downward, the water inlet check valve is closed and the water discharge check valve is opened. At this time, the coolant accumulated at the bottom will be discharged into the cooling water tank through the return pipe, thereby realizing secondary collection and utilization of the coolant.

[0024] A water cooling method for a laser cutting machine comprises the following steps:

[0025] Step 1: The worker places the cutting path of the workpiece in a horizontal cutting manner, and fixes it on the top of the cutting table with the help of a clamping tool, and then starts the drive frame to drive the laser generator to perform horizontal sliding cutting;

[0026] Step 2: When the housing slides horizontally through the driving frame, the reciprocating screw rotates under the meshing of the first gear block and the fixed gear, thereby driving the cooling plate to slide up and down on the outer wall of the laser generator. At the same time, during the sliding process of the cooling plate, under the action of the worm and worm gear, the atomizing nozzle rotates inside the cooling plate following the worm gear;

[0027] Step 3: As the cooling plate slides downward, the vertical rod is squeezed, causing the piston plate to move downward to discharge the coolant accumulated at the bottom of the shell into the cooling water tank through the return pipe. At the same time, when the cooling plate is reset, the coolant will accumulate at the bottom of the shell again through the fixed filter plate to cool the laser generator for the second time.

[0028] By adopting the above technical solution, the outer wall of the laser generator can be cooled as a whole, and the working efficiency of the laser generator can be improved. At the same time, the cooling liquid can be fully utilized, thereby accelerating the cooling efficiency of the laser generator as a whole.

[0029] In summary, the present invention mainly has the following beneficial effects:

[0030] 1. In the process of moving and cutting the laser generator, the first tooth block drives the fixed gear to rotate, and the reciprocating screw is rotated by the action of the transmission mechanism. In this process, the cooling plate drives the atomizing nozzle to slide up and down on the outer wall of the laser generator, so as to cool down the outer wall of the laser generator as a whole. At the same time, in the process of sliding up and down on the cooling plate, the second tooth block drives the driving gear to rotate, and the atomizing nozzle is driven to rotate on the inner side of the cooling plate through the cooperation of the worm and the worm wheel. In this process, the contact area between the coolant and the outer wall of the laser generator is further increased, thereby ensuring the overall cooling effect and improving the working efficiency of the laser generator.

[0031] 2. The present invention provides a fixed filter plate in the housing. When the cooling plate slides downward, the vertical rod is squeezed. At this time, the vertical rod drives the piston plate to slide downward. In this process, the coolant accumulated at the bottom of the housing is squeezed into the return pipe, so that the cooled coolant is recycled for the second time. In this process, the waste of coolant is greatly reduced. At the same time, the coolant will gather at the bottom of the housing during the subsequent resetting process, so that the cooled coolant can cool the bottom of the laser generator for the second time, so that the coolant is fully utilized and the overall cooling efficiency is accelerated.

[0032] 3. The present invention provides an annular flow channel on the outer wall of the shell, and the coolant sprayed by the atomizing nozzle will accumulate in the annular flow channel. At this time, the accumulated coolant will flow to the bottom through the annular flow channel under the action of its own gravity. In this process, the flow path of part of the coolant on the outer wall of the shell is extended, and the cooling time of the coolant on the outer wall of the shell is also extended, thereby further improving the utilization rate of the coolant.

DETAILED DESCRIPTION

[0043] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] The following describes an embodiment of the present invention based on its overall structure.

[0045] Embodiment 1

[0046] A water cooling device and water cooling method for a laser cutting machine, such as Figure 1-Figure 8 As shown, it includes a cutting table 1, a driving frame 2, a shell 4, a laser generator 5, a transmission mechanism 13, a cooling mechanism and a collecting mechanism. The staff arranges the cutting path of the workpiece in a horizontal cutting manner, and fixes it on the top of the cutting table 1 by the action of a clamping tool, and then starts the driving frame 2 to drive the laser generator 5 to perform horizontal sliding cutting. Since a first tooth block 3 is provided on one side of the driving frame 2, and a fixed gear 12 meshing with the first tooth block 3 is rotatably provided in the shell 4, when the driving frame 2 drives the laser generator 5 to perform sliding cutting, the first tooth block 3 will drive the fixed gear 12 to rotate, and a transmission mechanism 13 is connected to the top of the fixed gear 12, and the other end of the transmission mechanism 13 is connected to the reciprocating screw 9. When the fixed gear 12 rotates through the first tooth block 3, the transmission mechanism 13 on the top will be driven to rotate, thereby driving the reciprocating screw 9 at the other end of the transmission mechanism 13 to rotate;

[0047] A screw sleeve 14 is slidably provided on the outer wall of the reciprocating screw 9, and one side of the screw sleeve 14 is connected to the cooling plate 15. When the reciprocating screw 9 rotates, the screw sleeve 14 is driven to slide back and forth on the outer wall of the reciprocating screw 9, thereby driving the cooling plate 15 to slide up and down on the outer wall of the laser generator 5 for cooling, thereby cooling the outer wall of the laser generator 5 as a whole. At the same time, a second tooth block 21 is provided on the inner wall of the housing 4, and a driving gear 17 cooperating with the second tooth block 21 is rotatably connected at the cooling plate 15. At one end of the driving gear 17 A worm 18 is connected to the cooling plate 15, and a worm wheel 19 is meshed on one side of the worm 18. At the same time, an array of atomizing nozzles 20 are evenly arranged on the inner wall of the worm wheel 19. When the cooling plate 15 slides up and down, the second gear block 21 drives the driving gear 17 to rotate. Through the cooperation of the worm 18 and the worm wheel 19, the atomizing nozzle 20 is driven to rotate on the inner side of the cooling plate 15. In this process, the contact area between the coolant and the outer wall of the laser generator 5 is further increased, thereby ensuring the overall cooling effect and improving the working efficiency of the laser generator 5.

[0048] At the same time, a fixed filter plate 10 is installed in the shell 4, and a piston plate 22 is slidably arranged at the bottom of the fixed filter plate 10, and blocks 25 are arranged at both ends of the piston plate 22, and the top of the block 25 is connected with a vertical rod 23, wherein a compression spring 24 is connected between the block 25 and the inner wall of the shell 4, and the vertical rod 23 at the bottom is squeezed during the downward sliding of the cooling plate 15, and at this time, the piston plate 22 is driven to move downward under the action of the vertical rod 23, and the coolant accumulated at the bottom of the shell 4 is squeezed into the return pipe 8 during this process, so as to realize the secondary recovery of the cooled coolant, which greatly reduces the waste of the coolant. At the same time, the compression spring 24 itself is in a stretched state. When the cooling plate 15 is reset subsequently, the piston plate 22 is reset and slid by the reset action of the compression spring 24, so that the cooled coolant performs secondary cooling on the bottom of the laser generator 5, so as to realize the full utilization of its coolant and accelerate the overall cooling efficiency.

[0049] See also Figure 3 One end of the water inlet pipe 6 passes through the shell 4 and is connected to a branch pipe 11, and the number of the branch pipes 11 corresponds to the atomizing nozzle 20. The other end of the branch pipe 11 passes through the cooling plate 15 and is connected to the atomizing nozzle 20. The coolant in the cooling water tank 7 is discharged into the branch pipe 11 through the water inlet pipe 6, and then atomized and sprayed out through the atomizing nozzle 20. A rotating groove 16 is provided on the top of the cooling plate 15 for the branch pipe 11 to rotate with the worm gear 19. In the process of the worm gear 19 driving the atomizing nozzle 20 to rotate, the rotating groove 16 on the cooling plate 15 facilitates the branch pipe 11 to rotate together, and during the rotation, the branch pipe 11 can rotate orderly at the connection with the water inlet pipe 6.

[0050] See also Figure 1 and Figure 3 A water inlet check valve and a water discharge check valve are respectively provided on the piston plate 22 and the return pipe 8. Under normal conditions, the coolant will flow to the piston plate 22 after passing through the fixed filter plate 10. The gravity of the coolant itself will cause the water inlet check valve to open and the water discharge check valve to close. At this time, the coolant will accumulate at the bottom of the shell 4. Subsequently, when the piston plate 22 slides downward, the water inlet check valve is closed and the water discharge check valve is opened. At this time, the coolant accumulated at the bottom will be discharged into the cooling water tank 7 through the return pipe 8, so that the coolant can be collected and utilized for the second time.

[0051] See also Figure 4 The transmission mechanism 13 includes a driving disk, a transmission belt and a driven disk. One end of the fixed gear 12 is connected to the driving disk, and the other end of the driven disk is connected to the reciprocating screw 9. When the fixed gear 12 rotates, the driving disk will be driven to rotate, and the driven disk drives the reciprocating screw 9 to rotate under the action of the transmission belt. Since the diameter of the driving disk in the transmission mechanism 13 is larger than the diameter of the driven disk, when the driving disk drives the fixed gear 12 to rotate several times, the driven disk will drive the reciprocating screw 9 to rotate several times, thereby realizing that during the driving process of the drive frame 2, the cooling plate 15 can slide back and forth multiple times in the shell 4.

[0052] Embodiment 2

[0053] like Fig. 9 A water cooling device and water cooling method for a laser cutting machine shown in the figure have an overall structure similar to that of the first embodiment, wherein an annular flow channel 26 is provided on the outer wall of the outer shell 4, and the bottom of the annular flow channel 26 is concavely arranged, and the coolant sprayed through the atomizing nozzle 20 will accumulate in the annular flow channel 26. At this time, the accumulated coolant will flow to the bottom through the annular flow channel 26 under the action of its own gravity. In this process, the flow path of part of the coolant on the outer wall of the outer shell is extended, and the cooling time of the coolant on the outer wall of the outer shell is also extended, thereby further improving the utilization rate of the coolant, and the concave arrangement can effectively prevent the coolant from sliding toward the outer wall during the flow.

[0054] The working principle of the present invention is as follows: when in use, the housing 4 is mounted on one side of the driving frame 2, and then the workpiece to be processed is placed on the top of the cutting table 1, and the driving frame 2 is started to drive the housing 4 to slide back and forth. Since a first tooth block 3 is provided on one side of the driving frame 2, the fixed gear 12 in the housing 4 is driven to rotate under the action of the first tooth block 3, and the reciprocating screw 9 is rotated through the cooperation of the transmission mechanism 13. During this process, the cooling plate 15 in the housing 4 slides up and down in the housing 4, so as to realize the cooling of the outer wall of the laser generator as a whole, and during the sliding of the cooling plate 15 up and down, the atomizing nozzle 20 is driven to rotate on the inner side of the cooling plate 15 through the cooperation of the worm 18 and the worm wheel 19, thereby completing the cooling of the outer wall of the laser generator 5.

[0055] A piston plate 22 is provided at the bottom of the shell 4. When the cooling plate 15 slides downward, the vertical rod 23 is squeezed to move the piston plate 22 downward, so that the coolant accumulated at the bottom of the shell 4 is discharged through the return pipe 8, so that the cooled coolant is recovered for a second time. In the process of resetting the cooling plate 15, the piston plate 22 is reset by the action of the compression spring 24. At this time, the coolant flows to the bottom of the shell 4 through the fixed filter plate 10, so as to accumulate at the bottom of the shell 4 again, so that the cooled coolant can cool the bottom end of the laser generator 5 for a second time, so that the coolant is fully utilized.

[0056] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
