Description

Technical Field

[0001] This utility model relates to the field of metal component manufacturing technology, and in particular to a laser additive manufacturing equipment for metal component manufacturing. Background Technology

[0002] Metal components refer to structural parts or components made of metallic materials, which can be simple single parts or complex composite components. Laser additive manufacturing equipment for manufacturing metal components typically achieves repair, improvement of the outer surface, or addition of new functional outer layers by adding material to the outside of existing metal components.

[0003] When using existing laser additive manufacturing equipment, the metal component must first be placed on the equipment's placement platform. Then, the laser performs additive manufacturing by scanning the exterior of the metal component. Although existing equipment can effectively perform additive manufacturing on components that have been in use for many years, the component cannot be fixed in place on the platform during use. Since the additive manufacturing process involves the operation of the laser and the feeding system, these operations will generate vibrations or apply forces. If the metal component is not firmly fixed, it may move or shift during the additive manufacturing process, causing the laser beam to fail to accurately align with the target area. This deviation will directly affect the accuracy of the additive manufacturing, resulting in the final product not meeting the design requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a laser additive manufacturing equipment for manufacturing metal components, which aims to improve the problem in the prior art that the laser beam may move or deviate during the additive manufacturing process, resulting in the laser beam not being able to accurately align with the target area. This deviation will directly affect the accuracy of the additive manufacturing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A laser additive manufacturing apparatus for manufacturing metal components includes:

[0007] A bracket is a basic installation component for an overall laser additive manufacturing equipment. A housing is fixedly connected to the upper part of the bracket. An electric push rod is fixedly connected to the top of the housing. A laser additive is fixedly connected to the output end of the electric push rod. An installation cavity is opened inside the housing. A filter box is fixedly connected inside the bracket. An installation shell is fixedly connected to the outside of the filter box. An air outlet is fixedly connected to the right side inside the installation shell. A placement platform is fixedly connected inside the housing.

[0008] A fixing mechanism, located inside the mounting cavity, is used to fix the metal component requiring additive manufacturing. The fixing mechanism includes a cylinder, which is fixedly connected inside the mounting cavity. A moving block is fixedly connected to the output end of the cylinder. One end of a rotating plate is rotatably connected to the outer periphery of the moving block. A guide rail is fixedly connected inside the housing. Multiple rotating plates are rotatably connected to the outer periphery of the guide rail. Slider blocks are slidably connected to both sides of the guide rail. Fixed rods are fixedly connected to both sides of the two sliders. The other end of the multiple rotating plates is rotatably connected to the outside of the multiple fixed rods. Connecting plates are fixedly connected to the upper part of the two sliders. Arc-shaped clamping plates are fixedly connected to the outside of the two connecting plates.

[0009] The filtration mechanism, located inside the mounting housing, is used to adsorb and filter the fumes generated during the additive manufacturing of metal components.

[0010] Furthermore, both of the arc-shaped plates are provided with protective pads inside, and the material of the two protective pads is rubber.

[0011] Furthermore, the filtration mechanism includes a fan, which is fixedly connected inside the mounting housing. A filter plate is inserted into the left side of the filter box, and an activated carbon adsorption plate is inserted into the right side of the filter box. One end of a conveying pipe is fixedly connected to the left side of the filter box. A smoke collection hood is provided on the left side of the box. The other end of the conveying pipe passes through the inside of the box and is fixedly connected to the inside of the smoke collection hood. An installation pipe is fixedly connected to the front side of the filter box. A guide rod is fixedly connected inside the installation pipe. Sliding blocks are slidably connected to both sides of the guide rod. A return spring is provided in the middle of the two sliding blocks. The return spring is sleeved on the outside of the guide rod. A handle is fixedly connected to the front side of the two sliding blocks. An insertion rod is fixedly connected to the outside of the two sliding blocks.

[0012] Furthermore, mounting rods are fixedly connected to both sides of the exterior of the smoke collection hood, and the bottoms of the two mounting rods are fixedly connected to the inside left side of the housing.

[0013] Furthermore, the mounting tube has first through holes on both sides inside, and the two insertion rods are slidably connected inside the two first through holes.

[0014] Furthermore, both the filter plate and the activated carbon adsorption plate have insertion holes inside, and the two insertion rods are respectively inserted into the two insertion holes.

[0015] Furthermore, a second through hole is provided on the front side of the inside of the mounting tube, and the two grips are slidably connected inside the second through hole.

[0016] Furthermore, a transparent cabinet door is installed on the front side of the outer side of the box, and a handle is fixedly connected to the outside of the transparent cabinet door.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, when additive manufacturing of metal components, the transparent cabinet door is first opened, and the metal component is placed on the placement platform. Then, the cylinder is activated, causing the moving block to move downwards, which in turn drives four rotating plates and a fixing rod to move relative to each other on the guide rail. At this time, two arc-shaped clamping plates move relative to each other through the connecting plate, causing the protective pads to contact the two sides of the metal component, thus completing the fixation. This process ensures that the metal component remains stable during the additive manufacturing process, improving the precision and quality of the laser additive manufacturing operation, ensuring that each layer of material deposition meets the design requirements, and ultimately obtaining a high-quality finished product.

[0019] 2. In this invention, during the laser additive manufacturing process, a fan is started to draw in smoke through a fume hood and introduce it into a filter box via a delivery pipe. The smoke first passes through a filter plate to filter particulate matter, and then through an activated carbon adsorption plate to filter and adsorb harmful substances. The purified gas is discharged from the outlet. When the filter plate and activated carbon adsorption plate need cleaning, the sliding block is moved by the handle to disengage the insertion rod from the insertion hole, allowing the filter plate and adsorption plate to be pulled out for cleaning. During installation, releasing the handle causes a return spring to reinsert the insertion rod into the insertion hole, achieving convenient smoke adsorption, filtration, and filter plate cleaning, thus improving the safety and cleanliness of the working environment.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model is a laser additive manufacturing equipment for manufacturing metal components, comprising:

[0031] The bracket 1 is a basic installation component for the overall laser additive manufacturing equipment. A housing 2 is fixedly connected to the upper part of the bracket 1. An electric push rod 4 is fixedly connected to the top of the housing 2. A laser additive 5 is fixedly connected to the output end of the electric push rod 4. An installation cavity 6 is opened inside the housing 2. A filter box 10 is fixedly connected inside the bracket 1. An installation shell 11 is fixedly connected to the outside of the filter box 10. An air outlet 12 is fixedly connected to the right side inside the installation shell 11. A placement platform 9 is fixedly connected inside the housing 2. A transparent cabinet door 3 is installed on the front side of the outside of the housing 2. A handle is fixedly connected to the outside of the transparent cabinet door 3.

[0032] The bracket 1 facilitates the fixation of the housing 2. When adding metal components, the electric push rod 4 is activated to move the laser additive 5 to a suitable position. Then, the laser additive 5 is used to add metal components. The model of the laser additive 5 is EOSM290. The placement platform 9 facilitates the placement of metal components. The transparent cabinet door 3 allows the operator to check the metal component addition process in a timely manner.

[0033] Reference Figure 5 and Figure 6 The fixing mechanism 7 is located inside the mounting cavity 6 and is used to fix the metal components that need to be added. The fixing mechanism 7 includes a cylinder 701, which is fixedly connected inside the mounting cavity 6. A moving block 702 is fixedly connected to the output end of the cylinder 701. One end of a rotating plate 703 is rotatably connected to the outer periphery of the moving block 702. A guide rail 704 is fixedly connected inside the housing 2. Multiple rotating plates 703 are rotatably connected to the outer periphery of the guide rail 704. Slider blocks 705 are slidably connected to both sides of the guide rail 704. Fixing rods 706 are fixedly connected to both sides of the two sliders 705. The other end of the multiple rotating plates 703 is rotatably connected to the outside of the multiple fixing rods 706. A connecting plate 707 is fixedly connected to the upper part of the two sliders 705. An arc-shaped clamping plate 708 is fixedly connected to the outside of the two connecting plates 707. A protective pad 8 is provided inside the two arc-shaped clamping plates 708. The material of the two protective pads 8 is rubber.

[0034] When performing additive manufacturing on metal components, the transparent cabinet door 3 is first opened, and the metal component to be added is placed on the upper part of the placement platform 9. The transparent cabinet door 3 is designed not only to facilitate the placement and removal of components by the operator, but also to provide visual observation during the additive manufacturing process, ensuring the accuracy and safety of the operation. Then, cylinder 701 is activated, which drives the movable block 702 fixed at its output end to move downwards. When the movable block 702 moves downwards, it drives four rotating plates 703 rotatably connected to its outer perimeter to rotate outside the guide rail 704. The rotation of the rotating plates 703 further drives four fixed rods 706 fixed to their outer perimeter to move. These fixed rods 706 are connected to two sliders 705, causing the sliders 705 to move relative to each other along the outer perimeter of the guide rail 704. When the two sliders 705 move relative to each other, the two connecting plates 707 connected to them also move relative to each other. The relative movement of the connecting plates 707 guides two externally fixed arc-shaped clamping plates 708 to move relative to each other towards the metal component. As the two curved plates 708 approach each other, the two protective pads 8 inside them also move relative to each other until the two protective pads 8 are in close contact with the outer sides of the metal component, ensuring that the component is firmly fixed on the placement stage 9. This ensures that the metal component remains stable during additive manufacturing. Fixing the metal component effectively prevents the component from moving or shifting due to vibration or other external forces during additive manufacturing, ensuring that the laser beam can be accurately aligned with the area to be added. This fixing method can significantly improve the accuracy of additive manufacturing operations, ensuring that the deposition of each layer of material meets the design requirements, ultimately obtaining a high-quality finished product. The two protective pads 8 are made of rubber, which can avoid damage to the surface of the metal component and maintain the integrity and aesthetics of the component surface.

[0035] Reference Figure 4 and Figure 7The filter mechanism 13, located inside the mounting housing 11, is used to adsorb and filter the smoke generated during the additive manufacturing of metal components. The filter mechanism 13 includes a fan 1301, which is fixedly connected inside the mounting housing 11. A filter plate 1302 is inserted into the left side of the filter box 10, and an activated carbon adsorption plate 1303 is inserted into the right side of the filter box 10. One end of a conveying pipe 1304 is fixedly connected to the left side of the filter box 10. A smoke collection hood 1305 is located on the left side of the box 2. The other end of the conveying pipe 1304 passes through the inside of the box 2 and is fixedly connected to the inside of the smoke collection hood 1305. An installation pipe 1306 is fixedly connected to the front side of the filter box 10. A guide rod 1307 is fixedly connected inside the installation pipe 1306. Sliding blocks 1308 are slidably connected to both sides of the guide rod 1307. A return spring 1310 is provided in the middle of 308. The return spring 1310 is sleeved on the outside of the guide rod 1307. A handle 1309 is fixedly connected to the front side of the two sliding blocks 1308. An insertion rod 1311 is fixedly connected to the outside of the two sliding blocks 1308. Mounting rods 14 are fixedly connected to both sides of the outside of the smoke hood 1305. The bottom of the two mounting rods 14 is fixedly connected to the inside left side of the box 2. A first through hole 16 is opened on both sides of the inside of the mounting tube 1306. The two insertion rods 1311 are slidably connected to the inside of the two first through holes 16. An insertion hole 15 is opened in the inside of the filter plate 1302 and the activated carbon adsorption plate 1303. The two insertion rods 1311 are respectively inserted into the two insertion holes 15. A second through hole 17 is opened on the front side of the inside of the mounting tube 1306. The two handles 1309 are slidably connected to the inside of the second through hole 17.

[0036] During the fume treatment process, the generated fume is effectively drawn into the fume collection hood 1305 by starting the fan 1301, and then guided to the interior of the filter box 10 for treatment through the delivery pipe 1304. First, the fume passes through the filter plate 1302 inside the filter box 10. The main function of the filter plate 1302 is to filter particulate matter in the fume. It can capture larger particles, reducing the burden on the activated carbon adsorption plate 1303. Next, the pre-filtered fume passes through the activated carbon adsorption plate 1303. The activated carbon adsorption plate 1303 has a highly developed pore structure, which can effectively adsorb harmful substances in the fume, such as organic compounds, odors, and some gaseous pollutants. This step greatly improves the filtration effect, ensuring that the final exhaust gas is cleaner, thereby maintaining the safety of the working environment and air quality. The purified gas is finally discharged through the air outlet 12, ensuring a fresh and pollution-free operating environment. After a period of use, filter plates 1302 and activated carbon adsorption plates 1303 will accumulate a large amount of particulate matter and harmful substances. The operator can move the handles 1309 relative to each other. The relative movement of the two handles 1309 drives the two externally fixed sliding blocks 1308 to move relative to each other outside the guide rod 1307. During this process, the sliding blocks 1308 compress the return spring 1310 sleeved outside the guide rod 1307, causing the return spring 1310 to deform and provide a certain tension. As the sliding blocks 1308 continue to move, they drive the two externally fixed insertion rods 1311 to move synchronously. When the two insertion rods 1311 disengage from the insertion holes 15, the filter plates 1302 and activated carbon adsorption plates 1303 can be easily pulled out of the filter box 10 for easy cleaning or replacement. After cleaning or replacement, simply reinsert the filter plates 1302 and activated carbon adsorption plates 1303 into the filter box 10 and then release the two handles 1309. Under the reaction force of the return spring 1310, the insertion rod 1311 will automatically insert into the insertion hole 15, firmly fixing the filter plate 1302 and the activated carbon adsorption plate 1303 inside the filter box 10, ensuring that it can effectively filter smoke and harmful substances when used next time.

[0037] Working principle: When adding materials to metal components, first, open the transparent cabinet door 3 and place the metal component to be added on the upper part of the placement platform 9. Then, start the cylinder 701. The cylinder 701 moves the moving block 702 fixed at the output end downward. The downward movement of the moving block 702 causes the rotating plates 703 connected to the four sides to rotate outside the guide rail 704. When the four rotating plates 703 rotate, they cause the two sliders 705 fixed to the four fixed rods 706 to move relative to each other outside the guide rail 704. When the two sliders 705 move relative to each other, they cause the two connecting plates 707 fixed at the top to move relative to each other. The relative movement of the two connecting plates 707 causes the two externally fixed arc-shaped clamping plates 708 to move relative to each other. The relative movement of the two arc-shaped clamping plates 708 causes the two externally fixed arc-shaped clamping plates to move relative to each other. The two internally installed protective pads 8 move relative to each other, allowing them to contact the outer sides of the metal component to fix it. This facilitates the fixation of the metal component during additive manufacturing, preventing movement or displacement during the process and ensuring the laser beam is accurately aligned with the area to be added. This significantly improves the precision of the additive manufacturing operation, ensuring that each layer of material deposition meets design requirements and ultimately yields a high-quality finished product. Then, when dealing with the smoke generated during the laser additive manufacturing process, the fan 1301 is activated, drawing the smoke through the smoke hood 1305. The smoke is then transported through the delivery pipe 1304 to the interior of the filter box 10. First, the smoke... After passing through filter plate 1302, the smoke can filter particulate matter in the smoke. Then, the smoke passes through activated carbon adsorption plate 1303, which can filter and adsorb harmful substances in the smoke. Finally, the purified gas is discharged through air outlet 12. After the filter plate 1302 and activated carbon adsorption plate 1303 have been used for a period of time, the relative movement of the handles 1309 causes the two externally fixed sliding blocks 1308 to move relative to each other outside the guide rod 1307. When the two sliding blocks 1308 move relative to each other, they compress the return spring 1310 sleeved on the outside of the guide rod 1307, causing the return spring 1310 to deform under force. Then, the two sliding blocks... When block 1308 moves, it moves synchronously with the two externally fixed insert rods 1311, allowing the filter plate 1302 and activated carbon adsorption plate 1303 to be pulled out of the filter box 10 for cleaning by disengaging the two insert rods 1311 from the inside of the two insertion holes 15. During installation, simply insert the filter plate 1302 and activated carbon adsorption plate 1303 into the filter box 10, and then release the two handles 1309. Under the reaction force of the return spring 1310, the two insert rods 1311 will be inserted into the two insertion holes 15. This facilitates the adsorption and filtration of fumes generated during the additive manufacturing of metal components, and also facilitates the disassembly and cleaning of the filter plate 1302 and activated carbon adsorption plate 1303, improving the safety and cleanliness of the working environment.
