Description

Technical Field

[0001] The present invention relates to the technical field of laser selective melting additive manufacturing, and in particular to a method for verifying the forming quality of a flying additive manufacturing device with a moving wind field. Background Art

[0002] Selective Laser Melting (SLM) technology achieves rapid manufacturing of complex structural products by stacking metal powder layer by layer into a three-dimensional entity, liberates structural process design, and breaks through the technical barriers of traditional manufacturing technology in terms of material diversity, scale flexibility, and structural complexity. It is highly valued in the global advanced manufacturing field and is widely used in aerospace, shipbuilding, automotive and other fields.

[0003] As the demand for complex structural product sizes in various industries continues to increase, the size of the SLM equipment forming chamber at home and abroad has also been driven to increase. However, for traditional large-size SLM equipment, it uses a fixed galvanometer structure. When the size of the forming chamber is further increased, it will face problems such as poor wind field uniformity and multiple laser overlap areas, making it difficult to achieve high-quality laser forming of oversized parts. Therefore, the "flying printing equipment" that can realize the movement of the galvanometer system within the forming chamber has become one of the main solutions for high-quality forming of oversized SLM components.

[0004] The flying additive manufacturing equipment integrates a large number of scanning galvanometers on the movable gantry and forms a flying optical module, which moves sequentially on the forming format to achieve "printing while moving", and the wind field (air outlet and air suction port) is also integrated on the movable gantry to form a "follow-up wind field". Since the range of this type of follow-up wind field only covers 1 to 2 rows of galvanometers, it can avoid the impact of the increase in the format of the forming chamber on the wind field and greatly improve the quality of the wind field. However, due to its special structure and working mode, the follow-up wind field may also introduce new problems for laser forming quality control: for example, since the black slag in the printing process is easily incompletely sucked in or slightly blocked at the air suction port, black slag or large particles of powder may accumulate near the wind field suction port. For traditional structure SLM equipment, the air suction port is generally located outside the forming format range and will not affect the printed product; for the flying printing equipment, the air suction port moves across the entire format with the moving gantry, which is likely to cause the ratio of large particles of powder and black slag in the powder bed to increase, affecting the actual production laser forming quality. Therefore, it is necessary to systematically verify the quality of laser forming in the following wind field to ensure the reliability and production stability of the flight printing equipment in actual production.

[0005] As a new type of structural additive manufacturing equipment, the forming quality of flying additive manufacturing equipment under the following wind field has not been fully verified, and there is currently no systematic following wind field quality verification plan. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0007] The present invention provides a method for verifying the quality of follow-up wind field forming of a flying additive manufacturing device, the verification method comprising:

[0008] Design wind field verification characteristic components: The wind field verification characteristic components include a windshield and two groups of test specimens, which are located on the upwind side and the downwind side of the windshield respectively; each group of test specimens includes a metallographic test block and a tensile test bar;

[0009] Fixed gantry, in a fixed wind field, to conduct fixed wind field laser forming quality verification;

[0010] The gantry moves normally, and the mobile wind field laser forming quality verification is carried out in the mobile wind field.

[0011] By applying the technical solution of the present invention, a verification method for the forming quality of a flying additive manufacturing device in a moving wind field is provided. The verification method designs a special verification feature component for wind field verification, including a wind shield and two groups of test pieces, and performs laser forming quality verification in a fixed wind field and a moving wind field, respectively. The wind shield simulates the factors that may affect the laser forming quality, such as large-particle powder and black slag that may be introduced by the moving wind field, thereby improving the accuracy and reliability of the wind field laser forming quality verification. Compared with the prior art, the technical solution of the present invention can solve the technical problem that the prior art cannot realize the quality verification of flying additive manufacturing equipment in a moving wind field.

[0020] like Figures 1 to 4 As shown, according to a specific embodiment of the present invention, a method for verifying the quality of the following wind field forming of a flying additive manufacturing device is provided, and the verification method includes:

[0021] S1, design wind field verification characteristic components: the wind field verification characteristic components include a windshield and two groups of test specimens, the two groups of test specimens are located on the upwind side and the downwind side of the windshield respectively; each group of test specimens includes a metallographic test block and a tensile test bar;

[0022] S2, fixed gantry, in a fixed wind field, to conduct fixed wind field laser forming quality verification;

[0023] S3, the gantry moves normally, and the mobile wind field laser forming quality verification is carried out in the mobile wind field.

[0024] By using this configuration, a verification method for the quality of the forming of a flying additive manufacturing device in a moving wind field is provided. The verification method designs a special verification feature component for wind field verification, including a wind shield and two sets of test pieces, and performs laser forming quality verification in a fixed wind field and a moving wind field respectively. The wind shield simulates the factors that may affect the quality of laser forming, such as large particles of powder and black slag that may be introduced by the moving wind field, thereby improving the accuracy and reliability of the wind field laser forming quality verification.

[0025] Furthermore, in the present invention, a wind field verification characteristic component is first designed: the wind field verification characteristic component includes a wind shield and two groups of test pieces, and the two groups of test pieces are respectively located on the upwind side and the leeward side of the wind shield; any group of test pieces includes a metallographic test block and a tensile test rod.

[0026] Large-particle powder and black slag may cause defects such as unfused components during the laser forming process, affecting the quality of laser forming, and even causing deterioration of mechanical properties or cracking in printing in severe cases. In order to amplify the impact of wind field quality on forming quality, the present invention specially designs the wind field verification feature component and adds a wind shield. The forming of the wind shield can produce large-particle powder, black smoke and other forming impurities to simulate the actual flight printing follow-up wind field that may inhale particle powder and black slag. At the same time, a group of test pieces are set on the upwind side and leeward side of the wind shield for wind field quality comparison. The test pieces on the upwind side of the wind shield are less affected by particle powder, black smoke and other forming impurities than the test pieces on the leeward side.

[0027] like Figure 1 As shown, as a specific embodiment of the present invention, the wind shield can be configured as a plate-shaped entity with a curved surface, and the curved surface is convex toward the upwind side.

[0028] As another specific embodiment of the present invention, the metallographic test blocks in any group of test pieces may include continuous scanning metallographic test blocks and interlayer scanning metallographic test blocks. The continuous scanning metallographic test blocks are used to verify the forming quality at different positions; Figure 2 As shown in the figure, the interlayer scanning metallographic test block is scanned every several layers to make the metallographic structure in a critical dense state, so that the influence of large particles of powder and black smoke in the forming process is more obvious. By setting the interlayer scanning metallographic test block, the influence of large particles of powder and black smoke on the metallographic structure can be magnified.

[0029] As another specific embodiment of the present invention, the tensile test bars in any group of test pieces include a tensile horizontal bar and a tensile vertical bar, and the tensile horizontal bar and the tensile vertical bar are used for static load tensile in a sedimentary state to evaluate the mechanical property levels at different positions.

[0030] Furthermore, in the present invention, after the design of the wind field verification feature component is completed, the gantry is fixed, and the fixed wind field laser forming quality verification is performed in the fixed wind field. Specifically, the following steps are included:

[0031] S21, fixing the gantry, and determining the number and arrangement of wind field verification feature components in the fixed wind field according to the gantry structure and the wind field.

[0032] As a specific embodiment of the present invention, within the gantry size range, three groups of wind field verification feature components are arranged alternately in sequence along the blowing direction of the wind field. Among them, the three groups of wind field verification feature components can be evenly arranged along the blowing direction, such as Figure 3 As shown, they are arranged near the air outlet, in the middle of the gantry, and near the air intake.

[0033] S22, setting process parameters, keeping the gantry stationary, and using the flying additive manufacturing equipment to synchronously print each group of wind field verification feature components under different wind turbine powers. For any wind field verification feature component, the printing start time of the wind shield is earlier than the printing start time of the test pieces on both sides of the wind shield.

[0034] In this step, since the gantry remains stationary, multiple groups of wind field verification feature components can be printed synchronously to save printing time and improve verification efficiency. At the same time, the printing start time of the windshield in any wind field verification feature component is set earlier than the printing start time of the test pieces on both sides of the windshield, thereby ensuring that the large particles of powder and black slag brought by the formation of the windshield will not affect the quality of the test pieces on the downwind side.

[0035] In order to further increase the amount of large-particle powder and black smoke generated during the printing process of the windshield, the laser power in the windshield entity filling parameters can be set to 110% to 115% of the preset laser power, the scanning speed can be set to 75% to 80% of the preset scanning speed, and the distance can be set to 80% to 90% of the preset distance. The above settings increase the laser power of the windshield entity filling parameters by 10% to 15%, reduce the scanning speed by 20% to 25%, and reduce the distance by 10% to 20%, which can further increase the amount of large-particle powder and black smoke generated during the printing process of the windshield and amplify the influence of the wind field quality on the molding quality.

[0036] By changing the fan power, the forming quality at each position under different wind speeds can be verified. As a specific embodiment of the present invention, the fan power can be adjusted to 40%, 60% and 80% respectively.

[0037] S23, pre-processing the printed wind field verification feature component.

[0038] As a specific embodiment of the present invention, after printing is completed, the substrate is taken out from the flying additive manufacturing device, and the surface metal powder is cleaned until no metal powder remains on the surface; wire cutting is used to separate each feature from the substrate.

[0039] S24, the metallographic structure analysis of the longitudinal cross-section sampling of the metallographic test block after S23 pretreatment, the room temperature tensile mechanical property test of the tensile test bar after S23 pretreatment, the metallographic quality and mechanical properties of each position under different wind speeds were compared to verify the quality of laser forming in a fixed wind field.

[0040] Furthermore, in the present invention, after completing the fixed wind field laser forming quality verification, the gantry moves normally, and the mobile wind field laser forming quality verification is performed in the mobile wind field. Specifically, the following steps are included:

[0041] S31, determining the number and arrangement of wind field verification feature components in the mobile wind field according to the gantry moving position and the wind field.

[0042] As a specific embodiment of the present invention, in the forming chamber, four groups of wind field verification feature components are arranged in sequence along the blowing direction of the wind field. Among them, the four groups of wind field verification feature components can be evenly arranged along the blowing direction, such as Figure 4 As shown, they are respectively arranged at the starting position of the gantry, the 1 / 3 position of the gantry moving stroke, the 2 / 3 position of the gantry moving stroke and the end position of the gantry.

[0043] S32, setting process parameters, the gantry moves normally, and under different fan powers, using the flying additive manufacturing equipment to print each group of wind field verification feature components in sequence along the gantry movement direction. For any wind field verification feature component, the printing start time of the wind shield is earlier than the printing start time of the test pieces on both sides of the wind shield.

[0044] In this step, since the gantry moves in the forming chamber, multiple sets of wind field verification feature components need to be printed in sequence according to the moving direction of the gantry to verify the quality of the mobile wind field laser forming.

[0045] Similarly, in order to further increase the amount of large-particle powder and black smoke generated during the printing process of the windshield, in this step, the laser power in the windshield solid filling parameters can be set to 110% to 115% of the preset laser power, the scanning speed to 75% to 80% of the preset scanning speed, and the distance to 80% to 90% of the preset distance to amplify the influence of the wind field quality on the molding quality.

[0046] As a specific embodiment of the present invention, the adjustable fan power is 40%, 60% and 80% respectively.

[0047] S33, pre-processing the printed wind field verification feature component.

[0048] As a specific embodiment of the present invention, after printing is completed, the substrate is taken out from the flying additive manufacturing device, and the surface metal powder is cleaned until no metal powder remains on the surface; wire cutting is used to separate each feature from the substrate.

[0049] S34, the metallographic structure analysis of the longitudinal cross-section sampling of the metallographic test block after S33 pretreatment, the room temperature tensile mechanical property test of the tensile test bar after S33 pretreatment, the metallographic quality and mechanical properties of each position under different wind speeds were compared to verify the quality of mobile wind field laser forming.

[0050] In view of the structural characteristics of flying additive manufacturing equipment, the present invention provides a verification method for the following wind field forming quality of flying additive manufacturing equipment. The method artificially simulates factors that may affect the laser forming quality, such as large particle powder and black slag that may be introduced by the following wind field, and performs wind field laser forming quality verification in a fixed wind field and a mobile wind field respectively. The verification efficiency is high and can meet the verification accuracy requirements, thereby providing a guarantee for the reliability and production stability of subsequent flying additive manufacturing equipment in actual production.

[0051] In order to further understand the present invention, the following Figures 1 to 4 The verification method for the follow-up wind field forming quality of the flying additive manufacturing equipment of the present invention is described in detail.

The continuous scanning metallographic test blocks are set to be 15×15×15mm metallographic test blocks, which are used to verify the forming quality at different positions.

[0056] In order to amplify the influence of large-particle powder and black smoke on the metallographic structure, a layer scanning metallographic test block is set up, such as Figure 2 According to the metal powder grade used, scanning is set every 2 to 3 layers to make the metallographic structure in a critical dense state, so that the influence of large-particle powder and black smoke in the forming process is more obvious.
