Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to laser cutting equipment for automobile parts. Background Art

[0002] Existing automotive parts, such as control arm linings, are produced by laser cutting flat metal sheets into specific shapes, which are then subsequently stamped into suspension parts.

[0003] Laser cutting equipment focuses the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of metal cutting.

[0004] Laser cutting equipment uses a beam to replace the traditional mechanical knife. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It will gradually improve or replace traditional metal cutting process equipment, but there are still some shortcomings: At present, most laser cutting equipment is equipped with a workbench for use. The workbench is equipped with several supporting angle heads for supporting metal plates. However, with long-term use, the supporting angle heads will be disturbed by heat and cutting slag, resulting in the formation of welding-like slag on the supporting angle heads, which will gradually affect the horizontal support of the metal plates, and then cause the laser focus to fluctuate up and down, affecting the cutting accuracy. In addition, when the current laser equipment is cutting metal plates, the cut plates are also supported by the supporting angle heads, which are on the same plane as the plates to be retained. Therefore, after the plates are processed, they need to be manually peeled off, which increases the demand for manual operation.

[0005] In view of such a situation, the present invention provides a laser cutting device for automobile parts, aiming to solve the above-mentioned problems. Summary of the invention

[0006] In response to the above problems, the present application provides a laser cutting device for automotive parts, which solves the problem mentioned in the above background technology. At present, most laser cutting equipment will be equipped with a workbench for use. A number of supporting angle heads are provided on the workbench to support metal plates. However, with long-term use, the supporting angle heads will be disturbed by heat and cutting slag, resulting in the formation of welding-like slag on the supporting angle heads, which will gradually affect the horizontal support of the metal plates, and then cause the laser focus to fluctuate up and down, affecting the cutting accuracy. In addition, when the current laser equipment is cutting metal plates, the cut plates are also supported by the supporting angle heads, which are on the same plane as the plates to be retained. Therefore, after the plates are processed, they need to be manually peeled off, which increases the problem of manual operation requirements.

[0010] Furthermore, when the driving rod collides with one of the contact plates, the docking tube cooperates with the docking seat to transport the coolant into the pressure pipe, that is, the limit pin stretches spring 2 under the condition of water pressure. At this time, when the driving rod runs and collides with each contact plate, the limit pin at the position will extend to limit the contact plate and prevent the contact plate from being reset. When the driving rod collides with the other contact plate, the docking tube releases the cooperation with the cooling tube, that is, the limit pin will not extend. At this time, when the driving rod moves and collides with the contact plate, the contact plate is reset by spring 1.

[0011] Furthermore, the top of the base is fixedly connected to a fixed mold by bolts, a through groove is opened inside the fixed mold, a material plate of corresponding specifications and dimensions is placed in the through groove, and a single-sided retaining ring with a size of 5MM is provided on the inner wall of the through groove opened by the fixed mold, and the bottom of the material plate is in contact with the top of the retaining ring.

[0012] Furthermore, the cutting mechanism also includes two mounting brackets fixedly connected to the top of the base body, one side of the two mounting brackets is fixedly installed with a motor 1, the interior of the two mounting brackets is rotatably connected with a screw rod, one end of the screw rod is fixedly connected to one end of the output shaft of the mounting bracket, the outer walls of the two screw rods are threadedly connected with a translation table, the translation table is slidably connected between the two mounting brackets, the top of the translation table is fixedly connected with a motor 2, the top of the translation table is slidably connected with a fixed plate, the top of the translation table is rotatably connected with a rotating shaft, the outer wall of the rotating shaft is provided with a transmission belt, one end of the output shaft of the motor 2 is transmission-connected to the rotating shaft through the transmission belt, the fixed plate is fixedly connected to the outer wall of the transmission belt, a hydraulic rod is fixedly installed on the top of the fixed plate, the telescopic end of the hydraulic rod is fixedly connected with a laser cutter, and the driving rod is fixedly connected to the bottom of the translation table.

[0017] The beneficial effects of the present invention are as follows: (1) The laser cutting equipment for automobile parts described in the present invention cooperates with the support mechanism, the adjustment component and the drive rod. When the laser cutter moves, the drive rod will also move together and slide inside the base. During this period, the drive rod will contact the contact plate and apply pressure to it, so that the contact plate slides inside the mounting seat and stretches the spring 1 on one side and squeezes the spring 1 on the other side. The movement of the contact plate will cause the output tube to rotate, that is, drive the support angle head plate and the V-shaped injection head to move. Therefore, when the laser cutter moves and cuts, the support angle head plate directly below the laser cutter will move to avoid the vertical line of the focus of the laser cutter and will temporarily break away from contact with the metal plate, thereby reducing the laser heat received by the support angle head plate, thereby protecting the support angle head plate and reducing the formation of welding slag, so that the support angle head plate can remain intact, providing effective horizontal support for the metal plate, ensuring cutting accuracy and quality, and at the same time extending the service life of the support angle head plate.

[0018] (2) In the laser cutting equipment for automobile parts described in the present invention, the coolant is transported to the cooling pipe through a water pump, then enters the output pipe, and then is transported to each supporting angle head plate and sprayed out from the V-shaped spray head to cool the metal sheet, which can reduce the heat transfer of the metal sheet except for the laser focus. When the laser cutter is running, the coolant sprayed by the moving V-shaped spray head is not on the vertical line of the laser cutter's focus, while the other V-shaped spray heads cool other parts of the metal sheet. Therefore, this can also reduce the heat transfer of non-cutting points, prevent the internal characteristics of the metal sheet from changing due to heating, and affect the use requirements of the metal sheet.

[0019] (3) In the laser cutting equipment for automobile parts described in the present invention, when the driving rod contacts one of the contact plates, the butt joint tube slides inside the base, and one end of the butt joint tube cooperates with the butt joint seat. At this time, the coolant in the cooling tube is input into the pressure pipe through the butt joint tube and the transmission pipe. The limit pin will stretch the spring 2 under the water pressure. At this time, when the driving rod contacts the contact plate again, the limit pin at this place will extend after the contact plate moves, blocking the return of the contact plate until all the supporting angle head plates are moved. The metal sheet to be retained is temporarily supported by the retaining ring, and the metal sheet to be cut and removed will fall down onto the moving supporting angle head plate. Since the overall height of the supporting angle head plate will become lower after it moves, the removed metal sheet and the retained metal sheet are not on the same horizontal plane, which facilitates the subsequent manual material collection and the processing of the cut part.

Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] Example: like Figure 1-Figure 19As shown, an embodiment of the present invention provides a laser cutting device for automobile parts, including a base 1 and a cutting mechanism 2, a storage box 5 for storing coolant is fixedly installed on the top of the base 1, and also includes a support mechanism 3 movably arranged inside the base 1, an adjustment component 38 is arranged inside the support mechanism 3, and the cutting mechanism 2 includes a driving rod 29 and a laser cutter 28 running together; the support mechanism 3 is configured to support the metal plate, and the support mechanism 3 includes a base 31 and two mounting seats 33, the two driving rods 29 are slidably connected to the inside of the base 31, and a water pump is arranged inside the storage box 5, and the water pump is connected to one end of the cooling pipe 34 and is fixedly connected to the inside of the two mounting seats 33. There is a cooling tube 34, and a plurality of output tubes 39 are rotatably connected between the cooling tubes 34. The outer wall of the output tube 39 is fixedly connected to a supporting angle head plate 310. A plurality of V-shaped injection heads 311 are installed on one side of the supporting angle head plate 310. The inner cavity of the V-shaped injection head 311 is communicated with the inner cavity of the cooling tube 34. Both ends of the cooling tube 34 are plugged into the interior of the storage box 5. The adjustment component 38 includes a contact plate 3802, a limit pin 3803, a pressure pipe 3806 and a plurality of springs 1 3801 and springs 2 3804. The contact plate 3802 is fixedly connected to the outer wall of the output tube 39 and is located between the two springs 1 3801, that is, the contact plate 3802 is supported, limited and reset by the spring 1 3801.

[0025] In this embodiment, the coolant in the storage box 5 is transported to the cooling pipe 34 through a water pump, then enters the output pipe 39, and is then transported to each supporting angle head plate 310, and is sprayed out from the V-shaped spray head 311 to cool the metal sheet.

[0026] In this embodiment, the support mechanism 3 supports the metal sheet that needs to be laser cut, mainly supporting the top of the angle head plate 310 to support the bottom of the metal sheet, and then cutting it through the laser cutter 28 in the cutting mechanism 2, wherein when the laser cutter 28 moves, the driving rod 29 will also move together and slide inside the base 31. During this period, the driving rod 29 will contact the contact plate 3802 and apply pressure to it, so that the contact plate 3802 slides inside the mounting seat 33, and stretches the spring 1 3801 on one side thereof and squeezes the spring 1 3801 on the other side thereof, and the movement of the contact plate 3802 will cause the output tube 39 to rotate (the rotation angle is as shown in FIG. 2 ). Fig.15 As shown), that is, the support angle head plate 310 and the V-shaped injection head 311 are driven to move (as shown Figure 3As shown in the figure, when the laser cutter 28 is moving and cutting, the support angle head plate 310 directly below the laser cutter 28 will move to avoid the vertical line of the focus of the laser cutter 28, and will temporarily break away from the contact with the metal sheet, thereby reducing the laser heat received by the support angle head plate 310, thereby protecting the support angle head plate 310 and reducing the formation of welding slag, so that the support angle head plate 310 can remain intact and provide horizontal support for the metal sheet, which can also extend the service life of the support angle head plate 310; In addition, the coolant sprayed by the V-shaped spray head 311 can reduce the heat transfer of the metal sheet except for the laser focus (such as Figure 3 As shown in the figure, when the laser cutter 28 is cutting, the coolant sprayed by the V-shaped spray head 311 after movement is not on the vertical line of the focus of the laser cutter 28, while other V-shaped spray heads 311 are used to cool other parts of the metal sheet. Therefore, this can also reduce the heat transfer of non-cutting points, prevent the metal sheet from being heated and causing changes in its internal characteristics, affecting the use requirements of the metal sheet. When the laser cutter 28 leaves this place, the contact plate 3802 will be reset under the reset of the spring 1 3801, that is, the support angle head plate 310 and the V-shaped spray head 311 are reset; The establishment of the adjustment component 38 can control whether the contact plate 3802 can be reset, that is, whether the output pipe 39, the supporting angle head plate 310 and the V-shaped injection head 311 can be reset.

[0027] One end of spring 1 3801 is fixedly connected to the inside of the mounting seat 33, the other end of spring 1 3801 is fixedly connected to the contact plate 3802, the contact plate 3802 is slidably connected to the inside of the mounting seat 33, the pressure pipe 3806 is opened in the inside of the mounting seat 33, a plurality of springs 2 3804 are fixedly connected to the inside of the pressure pipe 3806, one end of the limit pin 3803 is fixedly connected to the pressure pipe 3806, the support mechanism 3 also includes a driving roller 32 arranged on both sides of the base 31, the driving roller 32 is driven by a motor, the inside of the base 31 is slidably connected to two docking pipes 36, both ends of the docking pipes 36 are fixedly connected to the contact plates 314, the outer wall of the cooling pipe 34 is fixedly connected to two docking seats 35, one side of the docking pipe 36 is plugged with a transmission pipe 37, the other end of the transmission pipe 37 is plugged into one side of the pressure pipe 3806, the top of the base 31 is fixedly connected to a fixed mold 312 by bolts, the inside of the fixed mold 312 is provided with a through groove, and the through groove is placed with corresponding specifications The material plate 313 is of a certain size, and the inner wall of the through groove opened by the fixed mold 312 is provided with a retaining ring with a single side of 5MM. The bottom of the material plate 313 contacts the top of the retaining ring. The interior of the mounting seat 33 is provided with a plurality of air-avoiding grooves 3805, and the limiting pin 3803 can be located in the air-avoiding grooves 3805. When the driving rod 29 conflicts with one of the abutting pieces 314, the butt joint 36 cooperates with the butt joint 35 to transport the coolant to the pressure pipe 3806, that is, the limiting pin 3803 is pulled under the water pressure. The second spring 3804 is extended. At this time, when the driving rod 29 runs and conflicts with each contact plate 3802, the limit pin 3803 at the position will be extended to limit the contact plate 3802 and prevent the contact plate 3802 from resetting. When the driving rod 29 conflicts with another contact plate 314, the docking tube 36 releases the cooperation with the cooling tube 34, that is, the limit pin 3803 will not be extended. At this time, when the driving rod 29 moves and conflicts with the contact plate 3802, the contact plate 3802 is reset by the spring 1 3801.

[0028] In this embodiment, there are two specific situations regarding whether the output pipe 39, the supporting angle head plate 310, and the V-shaped injection head 311 can be reset; First, when the driving rod 29 contacts one of the contact pieces 314, the butt joint 36 slides inside the base 31, and one end of the butt joint 36 cooperates with the butt joint 35. At this time, the coolant in the cooling pipe 34 is input into the pressure pipe 3806 through the butt joint 36 and the transmission pipe 37. The stop pin 3803 stretches the spring 2 3804 under the water pressure. At this time, when the driving rod 29 contacts the contact plate 3802 again, the stop pin 3803 at the contact plate 380 2 After the movement, it will extend out to block the reset of the resistance plate 3802 until all the support angle head plates 310 are moved. The metal sheet that needs to be retained is temporarily supported by the retaining ring, and the metal sheet that is cut and removed will fall down (falling on the support angle head plate 310 after it moves, but because the overall height of the support angle head plate 310 becomes lower after it moves, the removed metal sheet and the retained metal sheet are not on the same horizontal plane, which facilitates the subsequent manual material removal and the processing of the cut part.) 2. When the driving rod 29 contacts the other contact piece 314, the docking tube 36 is separated from the docking seat 35. At this time, after the driving rod contacts the contact plate 3802, the contact plate 3802 is reset under the reset of the spring 1 3801; The above two situations are respectively applied in the processing stage and the material taking stage after processing. Specifically, after the processing is completed, the butt joint 36 will be matched with the butt joint 35. After the match, the position of the driving rod 29 is in the following state: Figure 2 The position shown in FIG. 1 (which also shows the position of the cutting mechanism 2), and then the support mechanism 3 is moved to the position shown in FIG. Figure 1 The position shown, that is, during this movement, each contact plate 3802 is in conflict with the drive rod 29. It should be noted that during this movement, the support mechanism 3 does not have to move completely into place, especially the drive rod 29 cannot be released from the other contact plate 314. After the material is taken, the support mechanism 3 moves completely into place again, and the drive rod 29 will conflict with the other contact plate 314, that is, the docking tube 36 is separated from 35, and the limit pin 3803 will be reset under the reset force of the spring 2 3804, and the coolant in the pressure pipe 3806 can flow to the conveyor belt module 6 or other positions. At this time, other metal sheets that need to be processed can be added again.

[0029] The cutting mechanism 2 also includes two mounting frames 21 fixedly connected to the top of the base 1, one side of the two mounting frames 21 is fixedly installed with a motor 22, the interior of the two mounting frames 21 is rotatably connected with a screw rod 23, one end of the screw rod 23 is fixedly connected to one end of the output shaft of the mounting frame 21, the outer walls of the two screw rods 23 are threadedly connected with a translation stage 24, the translation stage 24 is slidably connected between the two mounting frames 21, the top of the translation stage 24 is fixedly connected with a motor 25, the top of the translation stage 24 is slidably connected with a fixed plate 27, the top of the translation stage 24 is rotatably connected with a rotating shaft, the outer wall of the rotating shaft is provided with a transmission belt 26, one end of the output shaft of the motor 25 is transmission-connected to the rotating shaft through the transmission belt 26, the fixed plate 27 is fixedly connected to the outer wall of the transmission belt 26, a hydraulic rod is fixedly installed on the top of the fixed plate 27, the telescopic end of the hydraulic rod is fixedly connected with a laser cutter 28, and a driving rod 29 is fixedly connected to the bottom of the translation stage 24.

[0030] In this embodiment, the screw rod 23 is driven to rotate by the motor 1 22, so that the threaded translation stage 24 moves in the X-axis direction, and the transmission belt 26 is driven by the motor 25 to move, which can drive the fixed plate 27 to move in the Y-axis direction. The movement of the hydraulic rod can drive the laser cutter 28 to move in the Z-axis direction to control the laser focus, so as to achieve the purpose of laser cutting of the metal sheet. The transmission belt 26 is connected to one end of the output shaft of the motor 2 25 and the rotating shaft through a pulley. This is the prior art and will not be described in detail. In this embodiment, the principle of the laser cutter 28 is to irradiate the surface of the metal sheet with a laser beam, causing the metal sheet to reach a melting point or a boiling point, and finally forming a cut. This is the prior art and will not be described in detail.

[0031] Two coiled tube modules 4 are fixedly installed on the top of the base 1, and both ends of the cooling tube 34 are respectively wound around the inside of the two coiled tube modules 4. A conveyor belt module 6 is fixedly installed inside the base 1, and a waste collection box 7 is placed on one side of the base 1. The waste collection box 7 is located below one end of the conveyor belt module 6.

[0032] In this embodiment, the two tube reel modules 4 can control the length of the cooling tube 34 when the support mechanism 3 moves. The tube reel module 4 is used to reel in and unfold the cooling tube 34. It should be noted that the cooling tube 34 in the tube reel module 4 must remain unobstructed. The conveyor belt module 6 can transfer some cutting residues to the waste collection box 7 for unified treatment.

[0033] How it works: When in use, select a fixed die 312 that matches the size of the metal sheet to be cut, fix it on the base 31 with bolts, and then place the metal sheet in the through slot opened in the fixed die 312; The screw rod 23 is driven to rotate by the motor 1 22, so that the threaded translation stage 24 moves in the X-axis direction. The transmission belt 26 is driven to move by the motor 25, which can drive the fixed plate 27 to move in the Y-axis direction. The movement of the hydraulic rod can drive the laser cutter 28 to move in the Z-axis direction to control the laser focus, so as to achieve the purpose of laser cutting of metal plates. The coolant in the storage box 5 is transported to the cooling pipe 34 through a water pump, then enters the output pipe 39, and then transported to each supporting angle head plate 310, and sprayed out from the V-shaped spray head 311 to cool the metal plate. The two coiling modules 4 can control the length of the cooling pipe 34 when the supporting mechanism 3 moves. The coiling module 4 is used to roll up and unfold the cooling pipe 34. It should be noted that the cooling pipe 34 in the coiling module 4 should be kept unobstructed. When the laser cutter 28 moves, the driving rod 29 also moves and slides inside the base 31. During this period, the driving rod 29 will contact the contact plate 3802 and apply pressure to it, so that the contact plate 3802 slides inside the mounting seat 33, stretching the spring 1 3801 on one side and squeezing the spring 1 3801 on the other side. The movement of the contact plate 3802 will cause the output tube 39 to rotate (the rotation angle is as shown in FIG. Fig.15 As shown), that is, the support angle head plate 310 and the V-shaped injection head 311 are driven to move (as shown Figure 3 As shown in the figure, when the laser cutter 28 is moving and cutting, the support angle head plate 310 directly below the laser cutter 28 will move to avoid the vertical line of the focus of the laser cutter 28, and will temporarily break away from the contact with the metal sheet, thereby reducing the laser heat received by the support angle head plate 310, thereby protecting the support angle head plate 310 and reducing the formation of welding slag, so that the support angle head plate 310 can remain intact and provide horizontal support for the metal sheet, which can also extend the service life of the support angle head plate 310; In addition, the coolant sprayed by the V-shaped spray head 311 can reduce the heat transfer of the metal sheet except for the laser focus (such as Figure 3 As shown in the figure, when the laser cutter 28 is cutting, the coolant sprayed by the V-shaped spray head 311 after movement is not on the vertical line of the focus of the laser cutter 28, while other V-shaped spray heads 311 are used to cool other parts of the metal sheet. Therefore, this can also reduce the heat transfer of non-cutting points, prevent the metal sheet from being heated and causing changes in its internal characteristics, affecting the use requirements of the metal sheet. When the laser cutter 28 leaves this place, the contact plate 3802 will be reset under the reset of the spring 1 3801, that is, the support angle head plate 310 and the V-shaped spray head 311 are reset; The establishment of the adjustment component 38 can control whether the contact plate 3802 can be reset, that is, whether the output pipe 39, the supporting angle head plate 310 and the V-shaped injection head 311 can be reset. Regarding whether the output pipe 39, the supporting angle head plate 310 and the V-shaped injection head 311 can be reset, there are two specific situations; First, when the driving rod 29 contacts one of the contact pieces 314, the butt joint 36 slides inside the base 31, and one end of the butt joint 36 cooperates with the butt joint 35. At this time, the coolant in the cooling pipe 34 is input into the pressure pipe 3806 through the butt joint 36 and the transmission pipe 37. The stop pin 3803 stretches the spring 2 3804 under the water pressure. At this time, when the driving rod 29 contacts the contact plate 3802 again, the stop pin 3803 at the contact plate 380 2 After the movement, it will extend out to block the reset of the resistance plate 3802 until all the support angle head plates 310 are moved. The metal sheet that needs to be retained is temporarily supported by the retaining ring, and the metal sheet that is cut and removed will fall down (falling on the support angle head plate 310 after it moves, but because the overall height of the support angle head plate 310 will become lower after it moves, the removed metal sheet and the retained metal sheet are not on the same horizontal plane, which facilitates the subsequent manual material removal and the processing of the cut part.) Second, when the driving rod 29 contacts the other contact piece 314, the docking tube 36 is separated from the docking seat 35. At this time, after the driving rod contacts the contact plate 3802, the contact plate 3802 is reset under the reset of the spring 1 3801; The above two situations are respectively applied in the processing stage and the material taking stage after processing. Specifically, after the processing is completed, the butt joint 36 will be matched with the butt joint 35. After the match, the position of the driving rod 29 is in the following state: Figure 2 The position shown in FIG. 1 (which also shows the position of the cutting mechanism 2), and then the supporting mechanism 3 moves to the position shown in FIG. Figure 1 The position shown, that is, during this movement, each contact plate 3802 is in conflict with the drive rod 29. It should be noted that during this movement, the support mechanism 3 does not have to move completely into place, especially the drive rod 29 cannot be released from the other contact plate 314. After the material is taken, the support mechanism 3 moves completely into place again, and the drive rod 29 will conflict with the other contact plate 314, that is, the docking tube 36 is separated from 35, and the limit pin 3803 will be reset under the reset force of the spring 2 3804, and the coolant in the pressure pipe 3806 can flow to the conveyor belt module 6 or other positions. At this time, other metal sheets that need to be processed can be added again.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
