Description

Technical Field

[0001] The invention relates to the technical field of laser shock strengthening, and in particular to a laser shock strengthening machine for the surface of a metal blind track plate. Background Art

[0002] Laser shock peening machine is a device that uses a high-energy density laser beam to strengthen the surface of metal materials. Its principle is based on laser-induced shock waves. When a short-pulse laser beam with high power density acts on the surface of the metal material, the absorption layer on the surface of the material will quickly absorb the laser energy and vaporize. The vaporized material will expand rapidly, generating a high-intensity shock wave. This shock wave acts on the surface of the material with extremely high pressure, causing the surface of the material to produce plastic deformation. The laser shock peening machine uses a high-energy density laser beam to irradiate the surface of the metal blind plate. When the laser beam acts on the absorption layer coated on the surface of the plate, the absorption layer quickly absorbs the laser energy and vaporizes, generating high-temperature and high-pressure plasma. The rapid expansion of the plasma will form a high-intensity shock wave, which acts on the surface of the metal plate with extremely high pressure, causing the surface to produce plastic deformation, thereby forming a residual compressive stress layer.

[0003] Metal tactile paving plates are a type of ground guidance facility material specially designed for the visually impaired. Through their special touch and texture, they help the visually impaired to walk safely and independently. They are mainly used for the laying of barrier-free passages in urban roads, public buildings, schools and other places. When laser shock strengthening is performed on the surface of metal tactile paving plates, during the laser shock strengthening process, when the laser beam acts on the absorption layer on the surface of the tactile paving plates, the absorption layer will quickly vaporize. When the high-temperature and high-pressure plasma generated by the vaporization expands, some of the incompletely vaporized materials and the surrounding tiny particles may splash out from the surface of the plate, thereby forming impurities and dust, which will then cause impurity splashing during processing. Summary of the invention

[0007] The collecting component comprises a collecting shell, the side surface of the collecting shell is fixedly connected to the inner side of the bracket, the inner side of the collecting shell is fixedly connected with a mesh plate, the bottom of the mesh plate is slidably connected with a connecting shaft, the bottom of the connecting shaft is fixedly connected with a connecting frame, a first spring is sleeved on the connecting shaft, the top of the first spring is fixedly connected to the bottom of the mesh plate, the bottom of the first spring is fixedly connected to the top of the connecting frame, the top of the connecting frame is fixedly connected with an ejection mechanism, the ejection mechanism is concentrically arranged with the mesh of the mesh plate, the bottom of the inner cavity of the collecting shell is fixedly connected with an air suction machine, the top of the air suction machine is provided with a collecting plate, the side surface of the collecting plate is fixedly connected to the inner side of the collecting shell, the top of the collecting plate is rotatably connected with a rotating mechanism, and both sides of the collecting shell are fixedly connected with a collecting box; during the laser shock strengthening process, when the laser beam acts on the absorption layer on the surface of the blind paving plate, the absorption layer will quickly vaporize, and the high temperature and high pressure plasma generated by the vaporization When the body expands, some incompletely vaporized materials and surrounding tiny particles may splash out from the surface of the plate, thereby forming impurities and dust. If the impurities and dust fall on the surface of the blind paving board, the flatness and finish of the plate surface may be affected. In the subsequent processing process, these impurities may be embedded in the surface of the plate, affecting the appearance and performance of the blind paving board. When the surface of the blind paving board is laser impact strengthened, the vacuum machine is turned on and the suction force generated by the vacuum machine is used to suck the waste generated during the processing into the collection shell through the mesh plate for collection. At the same time, the suction force generated by the vacuum machine causes the connecting frame to move downward through the connecting axis. At the same time, when the connecting frame moves downward, it drives the ejection mechanism to detach from the inner side of the mesh plate, sucks the waste into the collection shell, and drives the rotating mechanism to rotate on the collection plate, thereby driving the impurities accumulated on the collection plate to both sides, and then sweeping the impurities into the collecting box for collection.

[0008] Preferably, the ejection mechanism includes an ejection rod, the bottom of the ejection rod is fixedly connected to the top of the connecting frame, a sliding groove is opened on the side of the ejection rod, a sliding block is slidably connected to the inner side of the sliding groove, the side of the sliding block is fixedly connected to the sliding rod, the side of the sliding rod is slidably connected to the inner side of the ejection rod, an end of the sliding rod away from the sliding block is fixedly connected to an ejector pin, a second spring is sleeved on the sliding rod, the top of the second spring is fixedly connected to the ejector pin, and the bottom of the second spring is fixedly connected to the top of the ejection rod; a large amount of impurities enter the collection shell through the mesh plate, and when the laser strengthening work on the surface of the blind road plate is completed After the suction machine stops working, the connecting frame is driven by the reset stretching of the first spring, so that the connecting frame drives the ejection rod to move upward, so that the ejection rod drives the ejection block to move toward the mesh of the mesh plate, thereby ejecting the waste chips blocked in the mesh of the mesh plate. At the same time, when the extrusion pressure between the impurities and the inner side of the mesh of the mesh plate is too large, and the extrusion pressure between the ejector pin and the impurities is greater than the stretching force of the second spring, the sliding rod drives the ejector pin to move downward through the sliding block, and at the same time, the sliding block slides in the sliding groove, and the buffering work of the second spring is performed, so as to avoid excessive extrusion pressure between the impurities and the ejector pin, which will cause extrusion damage to the ejector pin impurities;

[0009] Preferably, the rotating mechanism includes a rotating block, the bottom of which is rotatably connected to the top of the collecting plate, both sides of the rotating block are fixedly connected with rotating rods, a rotating groove is provided on the side of the rotating rod away from the rotating block, a grabbing rod is rotatably connected to the inner side of the rotating groove, grabbing grooves are provided on both ends of the grabbing rod, a brush is fixedly connected to the side of the rotating rod close to the collecting plate, and the side of the brush away from the rotating rod is in contact with the top of the collecting plate; when a large amount of impurities enter the collecting shell through the suction force of the vacuum machine and then gather on the collecting plate, the suction force of the vacuum machine makes the rotating block drive the rotating rod to rotate on the collecting plate, so that the rotating rod drives the brush to clean the top of the collecting plate, thereby avoiding the accumulation of a large amount of impurities. The dust collecting plate is on the collecting plate, which will interfere with the normal ventilation of the collecting plate. At the same time, when the rotating rod rotates on the collecting plate, the rotating rod drives the impurities gathered on the top of the collecting plate to rotate, thereby swinging the impurities on the collecting plate to both sides, and throwing the impurities on the collecting plate into the collecting box. At the same time, when the rotating rod rotates, the grabbing rod is rotated in the rotating groove by centrifugal force. At the same time, grabbing grooves are provided on both sides of the grabbing rod, so that the dust that follows the impurities into the collecting shell is grabbed, thereby avoiding the phenomenon that when the brush rotates and cleans the top of the collecting plate, the dust attached to the collecting plate is swept into strips of dust, thereby entangled in the brush and the rotating block, thereby interfering with the cleaning work of the rotating rod.

[0010] Preferably, the transport component comprises a limit frame, the side surface of the limit frame is fixedly connected to the bracket, the inner side of the limit frame is fixedly connected to a transmission mechanism, the top of the limit frame is fixedly connected to a fixing frame, the inner side of the fixing frame is slidably connected to a connecting rod, a third spring is sleeved on the connecting rod, the top of the third spring is fixedly connected to the inner side of the fixing frame, the bottom of the third spring is fixedly connected to the top of the cleaning plate, and the end of the connecting rod away from the fixing frame is fixedly connected to the cleaning mechanism; the blind paving board is placed on the transmission mechanism, the blind paving board is driven by the transmission mechanism to be transported and moved, and the top of the blind paving board is cleaned by the cleaning mechanism, so that when the surface of the blind paving board is laser impact strengthened, its surface can be cleaned and other treatments can be performed to remove oil, impurities and oxide layer, so as to ensure that the laser can effectively act on the surface of the plate and improve the strengthening effect;

Since the angle of the bent plate is smaller than that of the rubber plate, the bent plate will not move against the top of the blind paving plate, but move with a gap between the top of the blind paving plate, so that the bent plate moves the blind paving plate At the same time, a rubber plate is arranged on the side of the connecting plate away from the bent plate, and the angle of the rubber plate is greater than that of the bent plate, so that the rubber plate can contact and move with the top of the blind paving board, thereby avoiding that when the blind paving board is processed, there will be residual impurities on the top of the blind paving board, thereby interfering with the processing work. The shape of the arc rubber plate can fit well with the surface of the plate. For materials such as blind paving boards that may have a certain curvature or uneven surface, the arc design of the arc rubber plate can closely contact various parts of the surface of the plate. For example, the raised stripes on the surface of the blind paving board can be cleaned along the curvature of the stripes without missing gaps and corners, effectively removing impurities and dust attached to these special shape areas, and at the same time, when the arc-shaped rubber plate contacts and cleans the blind paving board, it can also avoid friction damage to the top of the blind paving board.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention sets a collecting component. During the laser shock peening process, when the laser beam acts on the absorption layer on the surface of the blind paving board, the absorption layer will be rapidly vaporized. When the high-temperature and high-pressure plasma generated by the vaporization expands, some of the incompletely vaporized materials and the surrounding tiny particles may splash out from the surface of the plate, thereby forming impurities and dust. If the impurities and dust fall on the surface of the blind paving board, the flatness and smoothness of the surface of the plate may be affected. In the subsequent processing, these impurities may be embedded in the surface of the plate, affecting the appearance and performance of the blind paving board. When the surface of the blind paving board is subjected to laser shock peening, the suction machine is turned on and the suction force generated by the suction machine is used to suck the waste chips generated during the processing into the collection shell through the mesh plate for collection.

[0014] 2. The present invention provides an ejection mechanism so that a large amount of impurities enter the collecting shell through the mesh plate. After the laser strengthening work on the surface of the blind paving plate is completed and the air suction machine stops working, the connecting frame is driven by the reset stretching of the first spring, so that the connecting frame drives the ejection rod to move upward, so that the ejection rod drives the ejection block to move toward the mesh holes of the mesh plate, thereby ejecting the waste chips blocked in the mesh holes of the mesh plate. At the same time, when the extrusion pressure between the impurities and the inner side of the mesh holes of the mesh plate is too large, and the extrusion pressure between the ejector pin and the impurities is greater than the stretching force of the second spring, the sliding rod drives the ejector pin to move downward through the sliding block, and at the same time, the sliding block slides in the sliding groove, and the buffering work of the second spring is performed to avoid excessive extrusion pressure between the impurities and the ejector pin, which will cause extrusion damage to the impurities in the ejector pin.

[0015] 3. The present invention sets a rotating mechanism. When the rotating rod rotates, the grabbing rod rotates in the rotating groove by centrifugal force. At the same time, grabbing grooves are opened on both sides of the grabbing rod, so that the dust that follows the impurities into the collecting shell can be grabbed, thereby avoiding the phenomenon that when the brush rotates and cleans the top of the collecting plate, the dust attached to the collecting plate is swept into strips of dust, which are entangled on the brush and the rotating block, thereby interfering with the cleaning work of the rotating rod.

[0016] 4. The present invention places the tactile paving board on the transmission mechanism by setting a transport component, and drives the tactile paving board to be transported and moved by the transmission mechanism. At the same time, the top of the tactile paving board is cleaned by the cleaning mechanism. When the surface of the tactile paving board is laser impact strengthened, its surface can be cleaned and treated to remove oil, impurities and oxide layer, so as to ensure that the laser can effectively act on the surface of the plate and improve the strengthening effect.

When the paving board 5 is expanded, some of the incompletely vaporized materials and the surrounding tiny particles may splash out from the surface of the plate, thereby forming impurities and dust. If the impurities and dust fall on the surface of the blind paving board 5, the flatness and finish of the surface of the plate may be affected. In the subsequent processing process, these impurities may be embedded in the surface of the plate, affecting the appearance and performance of the blind paving board 5. When the surface of the blind paving board 5 is laser impact strengthened, the suction machine 48 is turned on, and the suction force generated by the suction machine 48 is used to suck the waste generated during the processing through the mesh plate 42 into the collection shell 41 for collection. At the same time, the suction force generated by the suction machine 48 makes the connecting frame 44 move downward through the connecting shaft 43. At the same time, when the connecting frame 44 moves downward, it drives the ejection mechanism 46 to separate from the inner side of the mesh plate 42, and sucks the waste into the collection shell 41. At the same time, it drives the rotating mechanism 49 to rotate on the collection plate 47, so that the impurities gathered on the collection plate 47 are driven to both sides, and then the impurities are swept into the material receiving box 410 for collection.

At the same time, when the extrusion pressure between the impurities and the inner side of the mesh of the mesh plate 42 is too large, and the extrusion pressure between the ejector pin 465 and the impurities is greater than the stretching force of the second spring 466, the sliding rod 464 drives the ejector pin 465 to move downward through the sliding block 463, and at the same time, the sliding block 463 slides in the sliding groove 462, and the buffering work of the second spring 466, so as to avoid the extrusion pressure between the impurities and the ejector pin 465 being too large, which will cause the ejector pin 465 to be squeezed and damaged by the impurities;

[0034] The rotating mechanism 49 includes a rotating block 491, the bottom of which is rotatably connected to the top of the collecting plate 47, and rotating rods 492 are fixedly connected to both sides of the rotating block 491. A rotating groove 493 is provided on the side of the rotating rod 492 away from the rotating block 491, and a grabbing rod 494 is rotatably connected to the inner side of the rotating groove 493.

[0035] Embodiment 2, use Figure 8-Figure 9 The laser shock strengthening machine for the surface of a metal blind paving plate of the present invention is described as follows;

[0036] like Figure 8-Figure 9 The present invention shows a laser shock peening machine for metal blind track plate surface, based on the first embodiment;

[0037] The transport component 3 includes a limit frame 31, the side of the limit frame 31 is fixedly connected to the bracket 1, the inner side of the limit frame 31 is fixedly connected to a transmission mechanism 32, the top of the limit frame 31 is fixedly connected to a fixing frame 33, the inner side of the fixing frame 33 is slidably connected to a connecting rod 34, a third spring 35 is sleeved on the connecting rod 34, the top of the third spring 35 is fixedly connected to the inner side of the fixing frame 33, the bottom of the third spring 35 is fixedly connected to the top of the cleaning plate 361, and the end of the connecting rod 34 away from the fixing frame 33 is fixedly connected to a cleaning mechanism 36; the blind paving board 5 is placed on the transmission mechanism 32, and the blind paving board 5 is driven by the transmission mechanism 32 to be transported and moved, and the top of the blind paving board 5 is cleaned by the cleaning mechanism 36, and then when the surface of the blind paving board 5 is laser impact strengthened, its surface can be cleaned and processed to remove oil, impurities and oxide layer, so as to ensure that the laser can effectively act on the surface of the plate and improve the strengthening effect;

[0038] The cleaning mechanism 36 includes a cleaning plate 361, both sides of the cleaning plate 361 are in contact with the inner side of the limit frame 31, the top of the cleaning plate 361 is fixedly connected to the bottom of the connecting rod 34, both sides of the inner cavity of the cleaning plate 361 are rotatably connected to cleaning rollers 362, the middle of the inner cavity of the cleaning plate 361 is fixedly connected to a connecting plate 363, one side of the connecting plate 363 is fixedly connected to a bent plate 364, and the side of the connecting plate 363 away from the bent plate 364 is fixedly connected to a rubber plate 365; when the blind paving board 5 is driven by the transmission mechanism 32 When the top of the blind paving board 5 contacts the first cleaning roller 362, the cleaning roller 362 can clean and wipe the surface of the blind paving board 5. When the blind paving board 5 continues to move through the transmission mechanism 32, the connecting plate 363 drives the bent plate 364 to move the top of the blind paving board 5. Since the angle of the bent plate 364 is smaller than that of the rubber plate 365, the bent plate 364 will not move against the top of the blind paving board 5, but move with a gap between the top of the blind paving board 5, so that The curved plate 364 scrapes off the larger and more adhesive impurities on the top of the blind paving board 5. At the same time, a rubber plate 365 is arranged on the side of the connecting plate 363 away from the curved plate 364. The angle of the rubber plate 365 is greater than that of the curved plate 364, so that the rubber plate 365 contacts and moves with the top of the blind paving board 5, thereby avoiding that when the blind paving board 5 is processed, impurities of components will remain on the top of the blind paving board 5 and interfere with the processing work. The shape of the arc rubber plate 365 can fit well with the surface of the plate. For materials such as the blind paving board 5 that may have a certain curvature or an uneven surface, the arc design of the arc rubber plate 365 can closely contact various parts of the surface of the plate, for example, the raised stripes on the surface of the blind paving board 5. The arc rubber plate 365 can clean along the curvature of the stripes without missing gaps and corners, effectively removing impurities and dust attached to these special shape areas. At the same time, when the arc-shaped rubber plate 365 contacts and cleans the blind paving board 5, it can also avoid friction damage to the top of the blind paving board 5.

[0039] The specific workflow is as follows:

[0040] During operation, the blind paving board 5 is placed on the transport component 3, and the transport component 3 drives the blind paving board 5 to pass through the coating component 7, and a layer of energy absorption coating is evenly coated on the surface of the blind paving board 5. Commonly used coating materials include black paint, aluminum foil, etc. The function of the coating is to absorb laser energy and quickly vaporize to generate plasma, thereby triggering shock waves. A constraint layer is arranged on the surface of the absorption layer, such as running water, K9 glass, etc. The constraint layer can constrain the expansion of plasma, increase the peak pressure of the shock wave, and prolong its action time, making the strengthening effect more significant. The blind paving board 5 is driven by the transport component 3 and continuously moved to the fixing component 6, and the blind paving board 5 is fixed manually. After that, the surface of the blind paving board 5 is laser-shock-hardened by the laser system 2. The laser generator generates a high-energy-density laser beam, which is accurately focused on a predetermined position on the surface of the blind paving board 5 by the beam transmission and focusing system. After the laser beam acts on the absorption layer, the absorption layer is rapidly vaporized to form plasma, and the plasma expands to generate a high-intensity shock wave. The shock wave acts on the surface of the plate, causing it to undergo plastic deformation, thereby forming a residual compressive stress layer. At the same time, the debris generated during the laser shock-hardening work is collected by opening the collecting component 4. After the processing, the blind paving board 5 is transported and unloaded through the transport component 3 on the other side.

[0041] The blind paving board 5 is placed on the transmission mechanism 32, and the blind paving board 5 is driven by the transmission mechanism 32 to be transported and moved. At the same time, the top of the blind paving board 5 is cleaned by the cleaning mechanism 36, and then when the surface of the blind paving board 5 is laser impact strengthened, its surface can be cleaned and treated to remove oil, impurities and oxide layer, so as to ensure that the laser can effectively act on the surface of the plate and improve the strengthening effect;

[0042] When the blind paving board 5 is driven to move by the transmission mechanism 32, when the top of the blind paving board 5 contacts the first cleaning roller 362, the cleaning roller 362 can clean and wipe the surface of the blind paving board 5. When the blind paving board 5 continues to move through the transmission mechanism 32, the connecting plate 363 drives the bent plate 364 to move the top of the blind paving board 5. Since the angle of the bent plate 364 is smaller than the rubber plate 365, the bent plate 364 will not move against the top of the blind paving board 5, but move with a gap between the top of the blind paving board 5, so that the bent plate 364 can scrape off the larger and more adhesive impurities on the top of the blind paving board 5. At the same time, a rubber plate 365 is provided on the side of the connecting plate 363 away from the bent plate 364, and the angle of the rubber plate 365 is greater than that of the bent plate 364. , so that the rubber plate 365 is in contact with and moves with the top of the blind paving board 5, thereby avoiding that when the blind paving board 5 is processed, impurities of components will remain on the top of the blind paving board 5 and interfere with the processing work. The shape of the arc rubber plate 365 can fit well with the surface of the plate. For materials such as the blind paving board 5 that may have a certain curvature or an uneven surface, the arc design of the arc rubber plate 365 can closely contact various parts of the surface of the plate. For example, the raised stripes on the surface of the blind paving board 5, the arc rubber plate 365 can be cleaned along the curvature of the stripes without missing gaps and corners, and effectively remove impurities and dust attached to these special shape areas. At the same time, when the arc-shaped rubber plate 365 contacts and cleans the blind paving board 5, it can also avoid friction damage to the top of the blind paving board 5.

[0043] During the laser shock peening process, when the laser beam acts on the absorption layer on the surface of the blind paving board 5, the absorption layer will be rapidly vaporized. When the high-temperature and high-pressure plasma generated by the vaporization expands, some of the incompletely vaporized materials and the surrounding tiny particles may splash out from the surface of the plate, thereby forming impurities and dust. If the impurities and dust fall on the surface of the blind paving board 5, the flatness and smoothness of the surface of the plate may be affected. In the subsequent processing process, these impurities may be embedded in the surface of the plate, affecting the appearance and performance of the blind paving board 5. When the surface of the blind paving board 5 is subjected to laser shock peening, the air intake is opened. The suction machine 48, through the suction force generated by the suction machine 48, sucks the waste chips generated during processing through the mesh plate 42 into the collection shell 41 for collection. At the same time, the suction force generated by the suction machine 48 makes the connecting frame 44 move downward through the connecting shaft 43. At the same time, when the connecting frame 44 moves downward, it drives the ejection mechanism 46 to separate from the inner side of the mesh plate 42, and sucks the waste chips into the collection shell 41. At the same time, it drives the rotating mechanism 49 to rotate on the collection plate 47, so as to drive the impurities gathered on the collection plate 47 to both sides, and then sweep the impurities into the receiving box 410 for collection.

[0044] A large amount of impurities enter the collecting shell 41 through the mesh plate 42. When the laser strengthening work on the surface of the blind paving board 5 is completed and the suction machine 48 stops working, the connecting frame 44 is driven by the reset stretching of the first spring 45, so that the connecting frame 44 drives the ejection rod 461 to move upward, so that the ejection rod 461 drives the ejection block to move toward the mesh of the mesh plate 42, thereby ejecting the waste chips blocked in the mesh of the mesh plate 42. At the same time, when the extrusion pressure between the impurities and the inner side of the mesh of the mesh plate 42 is too large, and the extrusion pressure between the ejector pin 465 and the impurities is greater than the stretching force of the second spring 466, the sliding rod 464 drives the ejector pin 465 to move downward through the sliding block 463, and at the same time, the sliding block 463 slides in the sliding groove 462, and the buffering work of the second spring 466, so as to avoid excessive extrusion pressure between the impurities and the ejector pin 465, which will cause extrusion damage to the impurities of the ejector pin 465.

[0045] When a large amount of impurities enter the collection housing 41 through the suction force of the air suction machine 48 and then gather on the collection plate 47, the suction force of the air suction machine 48 causes the rotating block 491 to drive the rotating rod 492 to rotate on the collection plate 47, so that the rotating rod 492 drives the brush 496 to clean the top of the collection plate 47, thereby preventing a large amount of impurities from accumulating on the collection plate 47 and interfering with the normal ventilation of the collection plate 47. At the same time, when the rotating rod 492 rotates on the collection plate 47, the rotating rod 492 drives the impurities gathered on the top of the collection plate 47 to rotate, thereby moving the impurities on the collection plate 47 to both sides. The impurities on the collecting plate 47 are swung into the material receiving box 410. At the same time, when the rotating rod 492 rotates, the grabbing rod 494 is rotated in the rotating groove 493 by centrifugal force. At the same time, grabbing grooves 495 are provided on both sides of the grabbing rod 494, so that the dust that follows the impurities into the collecting shell 41 can be grabbed, thereby avoiding the brush 496 rotating and cleaning the top of the collecting plate 47, sweeping the dust attached to the collecting plate 47 into strips of dust, thereby entangled in the brush 496 and the rotating block 491, and interfering with the cleaning work of the rotating rod 492.
