Description

Technical Field

[0001] The present invention relates to the field of laser processing technology, and in particular to a multi-module collaborative laser green repair metal remanufacturing device. Background Art

[0002] Laser green repair is a laser surface modification technology, which is to add green repair materials (powder feeding, wire feeding, presetting, etc.) to the surface of the workpiece (or base material), and through high-energy density laser heating, the green repair material and the thin layer of metal on the base surface quickly reach a molten state. At this time, relying on the heat conduction of the workpiece itself, it quickly solidifies and crystallizes into a green repair layer, so as to obtain a modified layer or repair layer that is metallurgically bonded with the base material and has a low dilution rate and various characteristics. Compared with traditional surface treatment technologies such as surfacing, thermal spraying, and electroplating, it has many advantages, such as a wide range of applicable material systems, controllable dilution rate of the green repair layer, metallurgical bonding between the green repair layer and the base, small thermal deformation of the base, and easy automation of the process. Therefore, since the 1980s, laser green repair technology has received widespread attention at home and abroad, and has been applied in many industrial fields.

[0003] For example, in the publications CN107627002A, CN107217257A, and CN106583726A, the positional relationship between the laser beam and the powder beam inside the nozzle has been disclosed. However, in actual use, the powder beam is pushed by gas to transport the powder beam to the molten pool area to achieve green repair forming. When the powder leaves the nozzle, the inertial force generated will cause the powder to deviate from the center of the pipeline output port when it is output to the feeding channel. Under the action of powder divergence, although a light-wrapped powder beam is used, the powder still cannot be wrapped by the entire molten pool. The powder overflowing to the outside of the molten pool cannot be melted, resulting in a low powder utilization rate. Part of the overflowed powder will adhere to the surface of the green repair layer, causing problems such as poor surface roughness, and cannot be accurately coaxially coupled with the light beam, affecting the forming accuracy and quality of the metal 3D parts. In addition, the hose connecting the powder feeder and the nozzle is relatively long, causing pressure loss in the powder feeder, unstable powder feeding rate, and affecting the forming quality and efficiency. In addition, the nozzle will drive the movement of the hose during operation, causing unstable powder transmission, which will ultimately affect the forming accuracy. Summary of the invention

[0017] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0018] See attached Figure 1-Figure 11As shown, a multi-module collaborative laser green repair metal remanufacturing device includes a support frame 1 and a gas cylinder 7. A connecting frame 2 is fixedly installed on the top of the support frame 1, and a shell 3 is fixedly installed on the other end of the connecting frame 2. A powder conveying component is arranged inside the shell 3, and a powder storage tank 31 for storing powder is arranged on the top of the shell 3. A laser 6 capable of green repairing the powder is fixedly installed on the back of the support frame 1, and the gas cylinder 7 is connected to the powder storage tank 31 through a gas pipe 71.

[0019] The powder conveying assembly includes a fixed seat 34 arranged inside the shell 3, a driving motor 33 is fixedly installed on the upper surface of the fixed seat 34, the top of the driving motor 33 is rotatably connected to the powder conveying turntable 32, a first funnel 35 is arranged on one side of the top of the driving motor 33, a second funnel 36 is arranged on one side of the bottom of the fixed seat 34, a conveying pipe 38 capable of conveying powder to the surface of the substrate 5 is arranged at the bottom of the second funnel 36, the bottom of the conveying pipe 38 extends downward to the outside of the shell 3, and a turntable scraper in contact with the upper surface of the powder conveying turntable 32 is arranged at the bottom of the powder storage tank 31; The diameter of the second funnel 36 is greater than that of the first funnel 35, and the first funnel 35 is located on one side of the top of the second funnel 36. The fixing seat 34 is fixedly connected to the inner wall of the outer shell 3 by bolts, and the connecting seat 37 is fixedly connected to the inner wall of the outer shell 3 by bolts; when it is necessary to squeeze the powder into the surface of the powder conveying turntable 32 through the powder storage tank 31, the driving motor 33 rotates the powder conveying turntable 32 counterclockwise, so that the powder conveying turntable 32 scrapes the powder into the second funnel 36 through the turntable scraper, driving the powder to pass through the first funnel 35 and the second funnel 36 in turn and convey it to the upper surface of the substrate 5.

[0020] The outer shell 3 seals and wraps the powder conveying assembly, so that after the gas cylinder 7 conveys gas into the powder storage tank 31 through the gas pipe 71, the powder stored in the powder storage tank 31 is input onto the powder conveying turntable 32, and then the driving motor 33 is started, so that the driving motor 33 drives the powder conveying turntable 32 to rotate counterclockwise, so that the powder conveying turntable 32 drives the powder to move to the turntable scraper, and then the turntable scraper scrapes the powder on the powder conveying turntable 32 into the first funnel 35, and uniformly enters the second funnel 36, and finally flows into the corresponding position on the substrate 5 through the conveying pipe 38. The device uses the outer shell 3 and the gas cylinder 7 and cooperates with the powder conveying assembly to avoid the problem that the pressure loss of the powder feeder and the unstable powder feeding rate caused by the long distance between the hose connecting the powder feeder and the nozzle affect the forming quality and efficiency, and also avoids the problem that the movement of the hose during the operation of the nozzle causes unstable powder transmission, which ultimately affects the forming accuracy.

[0021] As attached Figure 5As shown, the arrow on one side of the powder conveying turntable 32 is an arrow indicating the rotation direction of the powder conveying turntable 32, and the arrows at the powder conveying turntable 32, the first funnel 35, the second funnel 36, the conveying pipe 38 and the pre-scraping powder bundle 51 are arrows indicating the flow direction of the powder bundle.

[0022] As attached Figure 4 and attached Figure 6 As shown, the arrow at the laser 6 indicates the direction of the laser.

[0023] The front side of the support frame 1 is rotatably connected to a turntable 4, and a variety of scraper assemblies capable of adjusting the cross-section of the powder beam are arranged on the front side of the turntable 4. The variety of scraper assemblies include an adjustment seat 41 arranged on the front side of the turntable 4, and a plurality of adjustment seats 41 are arranged around the center of the turntable 4. A scraper capable of adjusting the cross-section of the powder beam is arranged on the outer side of each adjustment seat 41, and an adjustment mechanism capable of adjusting the position of the scraper is arranged on the adjustment seat 41; the scraper is composed of a middle rectangular scraper 42, two side rectangular scrapers 43 and a flat scraper 44, and the middle rectangular scraper 42, two side rectangular scrapers 43 and the flat scraper 44 are respectively connected to the corresponding adjustment seat 41, a groove is arranged in the middle part of the outer side of the middle rectangular scraper 42, a protrusion is arranged in the middle part of the outer side of the two side rectangular scrapers 43, and the outer side of the flat scraper 44 is arranged in a plane.

[0024] Since the printing requirements may be different each time, the scraper needs to be replaced frequently. The various scraper assemblies in the present solution can integrate various scrapers on a turntable 4. When the scraper needs to be replaced, the scraper does not need to be disassembled. You only need to rotate the turntable 4 to replace it with the corresponding middle rectangular scraper 42, the two side rectangular scrapers 43 or the flat scraper 44.

[0025] When the powder beam is conveyed to the substrate 5 through the powder conveying assembly, the turntable 4 is rotated as needed to move the corresponding middle rectangular scraper 42, the two side rectangular scrapers 43 or the flat scraper 44 to the bottom, and then the substrate 5 drives the powder to pass through the middle rectangular scraper 42, the two side rectangular scrapers 43 or the flat scraper 44 at the corresponding position in the multi-scraper assembly to form a powder beam of corresponding shape and thickness. This avoids the situation where the powder cannot be gathered into the molten pool due to the divergence of the powder beam itself after being conveyed to the substrate 5, resulting in irregular powder distribution. During the forming process, the dispersed powder will also adhere to the surface of the green repair layer, causing the surface of the green repair layer to be bumpy, resulting in poor surface roughness, poor precision of the formed parts, and poor quality.

[0026] Furthermore, the adjustment mechanism includes a tension bolt 46 disposed on the turntable 4 , and a second adjustment slot 45 is provided inside the adjustment seat 41 , and the adjustment seat 41 adjusts its position through the cooperation between the second adjustment slot 45 and the tension bolt 46 .

[0027] When the thickness of the powder on the substrate 5 needs to be controlled, the adjustment seat 41 can be released by rotating the tension bolt 46, and then the adjustment seat 41 is pulled to move and adjust on the surface of the tension bolt 46 through the second adjustment groove 45, and then the adjustment seat 41 is fixed by the tension bolt 46.

[0028] Furthermore, a fixing plate 61 connected to the support frame 1 is provided on one side of the laser 6. The laser 6 is composed of a laser emission head, a collimator lens and a shaping lens group. A connecting block 62 is fixedly installed on the back of the fixing plate 61. A first adjusting groove 12 is provided on the back of the support frame 1. A loosening screw 13 connected to the connecting block 62 is provided inside the first adjusting groove 12, and a spring capable of adjusting the height of the connecting block 62 is provided on the surface of the loosening screw 13. The top of the loosening screw 13 extends upward to the top of the connecting block 62, and a nut 14 capable of adjusting the tightness of the spring is provided on the top of the loosening screw 13. Through the cooperation between the connecting block 62 and the loosening screw 13, the loosening screw 13 is moved up and down by twisting the nut 14, squeezing or relaxing the spring, and the connecting block is connected thereto (such as Fig.10 As shown), the connecting block 62 can slide up and down. At the same time, since the connecting block 62 is connected to the fixing plate 61, and the fixing plate 61 is connected to the laser 6, the laser 6 can be driven to move up and down, and the position can be adjusted according to the defocus requirement.

[0029] In actual use, due to the different thicknesses of powder to be used, the height position of the laser 6 can be adjusted by loosening the screw 13 and the spring to achieve laser beam focus adjustment, so that the laser is at the optimal defocus amount each time printing is performed, which is used to cope with powder beams 52 after scraping of different thicknesses, thereby increasing the versatility of the device and improving the user experience.

[0030] Furthermore, the mounting plate 11 is fixedly connected to the support frame 1 by bolts, and threaded grooves are provided at both ends of the outer side of the mounting plate 11. The support frame 1 and the mounting plate 11 form an L-shaped support assembly. The connecting frame 2 consists of a vertical portion and an L portion. The bottom end of the vertical portion is fixedly connected to the upper surface of the support frame 1, and the top end of the vertical portion is fixedly connected to the top end of the L portion, and the bottom end of the L portion is fixedly connected to the upper surface of the outer shell 3.

[0031] By setting the threaded groove, the support frame 1 can be fixed at a specified position such as the inner wall of the device housing or the support frame through the mounting plate 11, and the setting of the L-shaped support assembly makes the positions of the powder conveying assembly, the multi-scraper assembly and the laser 6 correspond to the moving direction of the substrate 5.

[0032] As attached Figure 7-Figure 9As shown, the turntable 4 is rotated as needed to move the middle rectangular scraper 42, the two side rectangular scrapers 43 or the flat scraper 44 to the specified position on the substrate 5. After the pre-scraping powder beam 51 passes through the substrate 5 and passes through the middle rectangular scraper 42, the two side rectangular scrapers 43 or the flat scraper 44, a post-scraping powder beam 52 of a corresponding shape will be formed.

[0033] Among them, as attached Figure 7 As shown, when the middle rectangular scraper 42 is used, the powder passes through the empty space in the middle, producing the attached Figure 7 The shaved powder beam 52 is then focused on the shaved powder beam 52 by adjusting the shaping lens group in the laser 6, so that the laser 6 generates an intermediate laser beam spot 421 corresponding to the shaved powder beam 52, and then the intermediate laser beam spot 421 is directed to a specified position on the shaved powder beam 52 (such as the attached Figure 7 The shadow on the powder beam 52 after the middle scraping) is repaired with green color; As attached Figure 8 As shown, when the rectangular scrapers 43 on both sides are used, the powder can only pass through the empty space on both sides, resulting in the following Figure 8 The post-shaving powder beam 52 in the laser 6 is focused on the post-shaving powder beam 52 by adjusting the shaping lens group in the laser 6, so that the laser 6 generates a double laser beam spot 431 corresponding to the post-shaving powder beam 52, and then the double laser beam spot 431 is directed to a specified position on the post-shaving powder beam 52 (such as the attached Figure 8 The shadow on the powder beam 52 after the middle scraping) is repaired with green color; As attached Fig. 9 As shown, when a flat scraper 44 is used, since the flat scraper 44 is slightly lower, the powder can pass through the empty space below it, producing a Fig. 9 The post-shaving powder beam 52 in the laser 6 is focused on the post-shaving powder beam 52 by adjusting the shaping lens group in the laser 6, so that the laser 6 generates a plane laser beam spot 441 corresponding to the post-shaving powder beam 52, and then the plane laser beam spot 441 is directed to a specified position on the post-shaving powder beam 52 (such as the attached Fig. 9 Green repair is performed on the shadow area on the powder beam 52 after scraping.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
