Description

Technical Field

[0001] The present invention relates to the technical field of additive manufacturing, and in particular to a metal component manufacturing method, device and storage medium. Background Art

[0002] Metal additive manufacturing is a kind of additive manufacturing process with a wide range of applications and high maturity. According to different ways of feeding raw materials and different sources of raw material melting energy, it can be divided into powder bed fusion (PBF) and directed energy deposition (DED). Directed energy deposition technology has the advantages of high forming efficiency, large product size, and high material utilization. It is widely used in the manufacture of aircraft frame beams, aircraft tail nozzles, manned spacecraft frames and other products. It has achieved good results in weight reduction and structural optimization, but it also has the outstanding problem of "large residual stress in the forming process and high risk of component deformation or cracking".

[0003] Existing additive manufacturing methods generally adopt a method of interlacing printing and stress relief, and artificially divide the printing process into several sections. After each section is printed, the component is taken out of the forming chamber and subjected to stress relief treatment in the heat treatment workshop. After completion, the forming process is carried out again. Although this method can reduce the residual stress of the forming process in stages, it has the disadvantages of high consumption of protective gas, high risk of suffocation, part misalignment, and low efficiency due to the need to frequently remove and reposition parts. Summary of the invention

[0004] The purpose of the present invention is to provide a metal component manufacturing method, device and storage medium to solve the problems of large consumption of protective gas, high risk of suffocation, part misalignment and low printing efficiency in existing additive manufacturing methods for reducing residual stress.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] In a first aspect, the present invention provides a method for manufacturing a metal component, the method comprising:

[0007] Obtaining a current deposition manufacturing layer obtained by printing the metal component to be printed;

[0008] Performing temperature monitoring on the current deposition manufacturing layer, if the current deposition manufacturing layer has a first region whose temperature is higher than a first temperature value, obtaining the area of ​​the first region, and if the area of ​​the first region is greater than the first area value, pausing printing of the next deposition manufacturing layer;

[0009] If the current deposition manufacturing layer has a second region whose temperature is lower than the second temperature value, the area of ​​the second region is obtained; if the area of ​​the second region is greater than the second area value, the printing of the next deposition manufacturing layer is continued to obtain the metal component to be printed.

[0010] Compared with the prior art, the present invention provides a method for manufacturing a metal component. By monitoring the temperature of the current deposition manufacturing layer, stress accumulation due to temperature accumulation in additive manufacturing is avoided. When there is a first area in the current deposition manufacturing layer with a temperature higher than a first temperature value, the area of ​​the first area is obtained. If the area of ​​the first area is greater than the first area value, the printing of the next deposition manufacturing layer is suspended. At the same time, when there is a second area in the current completed deposition manufacturing layer with a temperature lower than a second temperature value, the area of ​​the second area is obtained. If the area of ​​the second area is greater than the second area value, the printing of the next deposition manufacturing layer is continued to obtain a metal component to be printed. The metal component can be prevented from being overheated due to long-term continuous printing, and the residual stress in the forming process is reduced, and the risk of deformation and cracking of the metal component due to stress is reduced. At the same time, the present method for manufacturing a metal component does not require frequent removal of the metal component from the forming chamber, thus avoiding stress relief heat treatment, making the operating environment more friendly, and improving printing efficiency.

[0011] In a second aspect, the present invention further provides a metal component manufacturing device, comprising:

[0012] A deposition manufacturing layer acquisition module, used to acquire the current deposition manufacturing layer obtained by printing the metal component to be printed;

[0013] a printing pause module, configured to monitor the temperature of the current deposition manufacturing layer, and if the current deposition manufacturing layer has a first region whose temperature is higher than a first temperature value, obtain the area of ​​the first region, and if the area of ​​the first region is greater than the first area value, suspend the printing of the next deposition manufacturing layer;

[0014] The continue printing module is used to obtain the area of ​​the second area if the current deposition manufacturing layer has a second area whose temperature is lower than the second temperature value, and if the area of ​​the second area is greater than the second area value, continue printing the next deposition manufacturing layer to obtain the metal component to be printed.

[0015] Compared with the prior art, the beneficial effects of a metal component manufacturing device provided by the present invention are the same as the beneficial effects of a metal component manufacturing method described in the above technical solution, which will not be elaborated here.

[0016] In a third aspect, the present invention further provides a computer storage medium, wherein instructions are stored in the computer storage medium, and when the instructions are executed, the above-mentioned metal component manufacturing method is implemented.

[0018] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention. In the drawings:

[0020] Figure 2 The present invention is a schematic structural diagram of a metal component manufacturing device provided by the present invention. DETAILED DESCRIPTION

[0021] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and their order is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0022] It should be noted that, in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0023] In the present invention, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b and c, where a, b, c can be single or multiple.

[0024] Directed energy deposition uses a high energy density heat source, focused on the substrate, to form a small molten pool, while melting the raw materials delivered to the molten pool in the form of powder or wire. As the heat source moves forward, the deposited metal solidifies on the substrate to form a metal melt path, which overlaps each other according to the predefined pattern fill distance. After the deposition is completed, the deposited layer is moved up to the next layer. Therefore, the deposition of all layers produces a 3D near-net shape component. Residual stress will be generated in this process. The larger the printing area, the greater the residual stress accumulation. For large or super-large metal components, the accumulation of residual stress will be very large, and the risk of deformation or cracking will also increase. In addition, directed energy deposition needs to be formed in a forming chamber with protective gas. Existing additive manufacturing methods usually use printing and stress relief interlaced to avoid stress accumulation. Not only does it require frequent removal of parts and repositioning, the printing efficiency is low, but also the protective gas consumption is large, the risk of suffocation is high, and it is easy to cause part misalignment.

[0025] To solve the above problems, the present invention provides a metal component manufacturing method, device and storage medium. By monitoring the temperature of the currently printed deposition manufacturing layer and performing corresponding operations according to the monitored temperature, the excessive temperature of the metal component caused by long-term continuous printing can be avoided, thereby reducing the residual stress in the forming process. The following is an explanation with reference to the accompanying drawings.

[0026] See also Figure 1 The present invention provides a method for manufacturing a metal component, which is applied to an additive manufacturing device, such as Figure 1 As shown, the method comprises the following steps:

[0027] Step 101: Obtain the current deposition manufacturing layer of the metal component to be printed obtained by printing.

[0028] It can be understood that the current deposition manufacturing layer is the deposition manufacturing layer that is most recently printed.

[0029] As an optional method, a method for obtaining the current deposition manufacturing layer of the metal component to be printed obtained by printing is:

[0030] Obtaining a three-dimensional model of a metal component to be printed;

[0031] Slicing the three-dimensional model to obtain multiple slice layers;

[0032] Performing path filling on the multiple slice layers to obtain a printing path;

[0033] The metal component to be printed is printed according to the printing path to obtain a current deposition manufacturing layer.

[0034] The three-dimensional model of the metal component to be printed can be modeled using computer-aided design software, such as UG, CATIA, SOLIDWORKS, etc., and the established three-dimensional model can be converted into a common standard file type STL format.

[0035] Step 102: Monitor the temperature of the current deposition manufacturing layer. If the current deposition manufacturing layer has a first region with a temperature higher than a first temperature value, obtain the area of ​​the first region. If the area of ​​the first region is greater than the first area value, suspend printing of the next deposition manufacturing layer.

[0036] Infrared thermal imaging equipment can be used to monitor the temperature of the current deposition manufacturing layer.

[0037] As an optional method, before the temperature of the current deposited manufacturing layer is monitored, it is necessary to obtain the cross-sectional area value of the current deposited manufacturing layer; the ratio of the first temperature value to the material melting point value is a first multiple; the first multiple is less than 1. The ratio of the first area value to the cross-sectional area value is a third multiple, and the third multiple is less than 1.

[0038] Step 103: If the current deposition manufacturing layer has a second area whose temperature is lower than the second temperature value, obtain the area of ​​the second area; if the area of ​​the second area is greater than the second area value, continue printing the next deposition manufacturing layer to obtain the metal component to be printed.

[0039] As an optional manner, the ratio of the second temperature value to the material melting point value is a second multiple; the material melting point value is the melting point value or the average melting point value of the material of the metal component to be printed. The first multiple and the second multiple are less than 1. The ratio of the second area value to the cross-sectional area value is a fourth multiple. The cross-sectional area value is the cross-sectional area value of the current deposition manufacturing layer currently being printed. The third multiple and the fourth multiple are less than 1.

[0040] Specifically, the first multiple can be 0.7, the second multiple can be 0.4, the third multiple can be 0.5, and the fourth multiple can be 0.8. That is, when the current deposition manufacturing layer has an area with a temperature exceeding 0.7Tf, and the cumulative area of ​​the area reaches more than 50% of the cross-sectional area of ​​the deposition manufacturing layer, the printing is suspended; when the current deposition manufacturing layer has an area with a temperature below 0.4Tf, and the cumulative area of ​​the area reaches more than 80% of the cross-sectional area of ​​the currently printed deposition manufacturing layer, the next deposition manufacturing layer is continued to be printed. Tf is the melting point of the material.

[0041] As an optional method, in the process of obtaining the printing path, the optimal path planning can be calculated in the computer software according to the initial parameters of the metal component to be printed in the three-dimensional model. The path planning may include the planned pause height, pause time and forming strategy. Among them, the planned pause height corresponds to the condition for pausing the printing of the deposition manufacturing layer. Since not every layer reaches the first temperature value during the printing process, but as the height of the deposition manufacturing layer increases, the temperature accumulates and increases, and finally the area of ​​the first temperature value in the pause printing condition appears, and the cumulative area of ​​the area reaches more than 50% of the cross-sectional area of ​​the deposition manufacturing layer. Therefore, the planned pause height can be set as the condition for pausing the printing of the deposition manufacturing layer, and the printing process can be simulated, that is, the temperature of the current deposition manufacturing layer and the area of ​​the temperature area during the printing process can be analyzed by simulation, and then the planned pause height can be determined. In addition, the pause time can be determined by simulating and analyzing the temperature of the deposition manufacturing layer printed during the pause period, and the printing is restarted when the conditions for continuing the deposition manufacturing layer printing are reached.

[0042] After calculating the printing path, the printing process is simulated in the computer software according to the printing path, and the printing process is simulated and analyzed. According to the simulation results, the calculated printing path is optimized and corrected by means of multi-parameter response surface analysis and principal component analysis until the deviation meets the requirements. The printing path is corrected and fed back by using simulation printing technology, which improves the rationality and accuracy of path planning.

[0043] As an optional manner, before slicing the three-dimensional model to obtain a plurality of slice layers, the step further includes:

[0044] Set material properties, additive manufacturing processing parameters, and the number of print heads.

[0045] As an optional method, the current deposition manufacturing layer is obtained by printing through a directed energy deposition additive manufacturing method, and the energy source can be laser, plasma or arc. The material for printing the metal component can be powder or wire.

[0046] The specific implementation process is as follows: a three-dimensional model of a metal component to be printed is imported into the printing software, and the material properties, additive manufacturing processing parameters, and the number of print heads in the additive manufacturing equipment are set; path planning is performed according to the three-dimensional model to obtain a printing path, and a printing process is simulated according to the printing path, the printing path is optimized and corrected, and the optimized printing path is imported into the additive manufacturing equipment to print the metal component. During the printing process, an infrared thermal imaging instrument is used to monitor the temperature of the currently printed deposition manufacturing layer. When an area with a temperature exceeding 0.7Tf appears in the current deposition manufacturing layer, and the cumulative area of ​​the area reaches more than 50% of the current printing cross-section, the printing of the next deposition manufacturing layer is suspended, and the printed deposition manufacturing layer is naturally cooled, and the temperature of the deposition manufacturing layer whose cooling process is suspended is continuously monitored. When an area with a temperature lower than 0.4Tf appears in the printed deposition manufacturing layer, and the cumulative area of ​​the area reaches more than 80% of the cross-sectional area of ​​the currently printed deposition manufacturing layer, the printing of the next deposition manufacturing layer is continued, and the above printing process is repeated to finally obtain the metal component to be printed.

[0047] Through the above-mentioned metal component manufacturing method and specific implementation process, it can be known that a metal component manufacturing method provided by the present invention controls the temperature of the metal component during the forming process online, thereby avoiding excessive temperature of the component caused by long-term continuous printing, reducing the residual stress in the forming process, and reducing the risk of deformation and cracking of the component due to stress; at the same time, the simulation printing technology is used to correct and feedback the path planning, which improves the rationality and accuracy of the path planning. In addition, there is no need to frequently take the component out of the forming chamber, which avoids stress relief heat treatment, makes the operating environment more friendly, and saves energy and reduces consumption.
