Description

TECHNICAL FIELD

[0001] The application relates to the technical field of titanium alloy forming processing, in particular to a high-temperature titanium alloy special-shaped ring forge piece preparation method and device based on a twin model. BACKGROUND

[0002] Titanium and titanium alloy are a new type of structural and functional material, which has high specific strength, excellent corrosion resistance and good high-temperature performance. However, due to the low hardness and poor wear resistance of titanium alloy, it cannot meet the actual production application requirements of many industries, therefore, a Ti65 alloy is designed by China, which is a multi-element composite reinforced near-alpha type high-temperature titanium alloy, and has excellent comprehensive performance such as high thermal strength, oxidation resistance and thermal stability at high temperature (such as 650 DEG C).

[0003] However, the high-temperature titanium alloy has poor forming process performance, and has problems such as smelting, forging and welding. The traditional titanium alloy special-shaped ring forge piece preparation method highly depends on manual operation, and the specific process includes: the operator needs to accurately control the ring forging equipment, and sequentially processes the titanium alloy bar through upsetting, punching, mandrel hole expansion, circular rolling and final forming and other processes, so as to obtain the target special-shaped ring forge piece. However, the preparation process with full manual participation has the following disadvantages: firstly, since the operator needs to directly intervene in each processing process, the operation error caused by human factors is difficult to avoid; secondly, when the operation error occurs, the traditional preparation method needs to rely on manual checking and correction one by one, which not only consumes time and effort, but also the correction effect is limited by the experience level of the operator, and there is great uncertainty.

[0004] Therefore, how to break through the technical bottleneck of the traditional preparation method and effectively improve the forming effect and processing efficiency of the target special-shaped ring forge piece has become a problem to be solved. SUMMARY

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] To better understand the embodiments of this application, the background technology will first be described in detail: In existing technologies, the traditional method for preparing titanium alloy irregular ring forgings is a fully manual process, which has the following drawbacks: First, because operators must be directly involved in each processing step, errors caused by human factors are difficult to avoid. For example, during the upsetting process, improper control of the operating force can easily lead to uneven stress distribution within the high-temperature titanium alloy bar; during the punching process, problems such as excessive hole diameter deviation or excessive hole wall roughness frequently occur; during the reaming process, the reaming amount and shape accuracy are difficult to guarantee; during the circular rolling process, fluctuations in rolling force may cause uneven forging thickness; and during the final forming process, die wear or operational errors can easily lead to dimensional deviations or surface defects in the forging. These errors accumulate and are transmitted through multiple processes, ultimately significantly reducing the forming effect of the target irregular ring forging, manifesting as insufficient geometric dimensional accuracy, uneven microstructure and properties, and surface quality defects.

[0022] Secondly, when operational errors occur, traditional manufacturing methods rely on manual inspection and correction of each part. This process is not only time-consuming and labor-intensive, but the effectiveness of the correction is also limited by the experience level of the operators, resulting in significant uncertainty. For example, forgings with uneven internal stress distribution require adjustment through complex heat treatment processes; forgings with out-of-tolerance dimensions may need to be reworked. These additional operations significantly extend the production cycle, leading to low processing efficiency for the entire irregular ring forging and making it difficult to meet the demands of modern industrial production for efficient and stable manufacturing.

[0023] Furthermore, traditional methods for preparing titanium alloy shaped ring forgings often employ shaped rolling mills and matching dies (such as shaped rolling dies) during the forming process of high-temperature titanium alloy bars. Specifically, pressure is applied through the shaped rolling mill, and the specific shape of the shaped rolling die forces the titanium alloy billet into plastic deformation to initially form the target shaped ring forging (such as a "trumpet-shaped" ring forging). However, besides the poor forming effect of the target shaped ring forging due to insufficient tonnage of the shaped rolling mill, the entire process also suffers from drawbacks such as complex titanium alloy forming technology, low material utilization, long production cycle, and high die costs.

[0024] Therefore, how to break through the technical bottlenecks of traditional preparation methods and effectively improve the forming effect and processing efficiency of the target irregular ring forgings has become an urgent problem to be solved.

[0025] To address the aforementioned technical problems, this application provides a method for preparing high-temperature titanium alloy irregular-shaped ring forgings based on a twin model. The method involves constructing a three-dimensional digital twin model of the high-temperature titanium alloy bar based on collected three-dimensional scanning data and material properties; acquiring real-time deformation data of the ring forging equipment during the forming process; updating the model parameters of the three-dimensional digital twin model in real time based on the deformation data; generating equipment adjustment instructions based on the model parameters; and controlling the adjusted ring forging equipment to continue forming the high-temperature titanium alloy bar to obtain the target irregular-shaped ring forging. This method, by constructing a three-dimensional digital twin model of the high-temperature titanium alloy bar, achieves intelligent control of the forming process, eliminating the need for manual intervention and effectively improving the processing efficiency and forming effect of the target irregular-shaped ring forging.

[0026] It should be noted that, since the above-mentioned method for preparing high-temperature titanium alloy irregular ring forgings based on twin models is applicable to fields with high requirements for material properties, it can be applied to aerospace (such as engine blades and turbine disks), energy (such as oil, natural gas and nuclear energy, used to manufacture high-pressure vessels, pipe fittings and reactor components, etc.), chemical and marine engineering (used to manufacture corrosion-resistant pipes, valves and pump bodies, etc.), medical devices (used to manufacture artificial joints, dental implants and surgical instruments, etc.), and automobile manufacturing (used to manufacture high-performance engine components, suspension systems and transmission systems, etc.), as well as other fields with extremely high precision requirements for parts.

[0027] Optionally, the execution subject of the above-mentioned method for preparing high-temperature titanium alloy irregular ring forgings based on twin models can be a high-temperature titanium alloy irregular ring forging preparation device based on twin models, or an electronic device, without specific limitations here.

[0028] Optionally, the electronic device may include: a computer, a mobile terminal, a main control device, electronic assembly equipment, and electrical equipment manufacturing equipment, etc.

[0029] The following uses an electronic device as an example to illustrate in detail the method for preparing high-temperature titanium alloy irregular ring forgings based on a twin model provided in this application: Figure 1 This is a schematic flowchart of the method for preparing high-temperature titanium alloy irregular ring forgings based on a twin model, provided in an embodiment of this application. Figure 1 As shown, the method includes the following steps 101-104.

[0030] Step 101: Based on the collected three-dimensional scanning data and material properties of the high-temperature titanium alloy bar, construct a three-dimensional digital twin model of the high-temperature titanium alloy bar.

[0031] Among them, high-temperature titanium alloy bars are rod-shaped metal materials with a certain diameter and length, with titanium as the main alloying element. They are also the initial processing raw materials. After a series of titanium alloy forming operations, they are gradually transformed into forgings of the target shape (i.e., target irregular ring forgings, such as "trumpet mouth" irregular ring forgings).

[0032] 3D scanning data refers to a series of digital data obtained by comprehensively and accurately acquiring spatial information such as the surface geometry, dimensions, and contours of high-temperature titanium alloy bars through specific 3D scanning technologies. This data is presented in the form of point clouds, meshes, etc., and can accurately describe the shape characteristics of the high-temperature titanium alloy bar in three-dimensional space, including details such as length, diameter, roundness, surface roughness, and the location and shape of possible defects. Specifically, this 3D scanning data is acquired by one of the following scanning devices: laser 3D scanner, structured light 3D scanner, or industrial computed tomography (CT) scanner.

[0033] Material properties refer to the inherent physical, chemical, and mechanical properties of high-temperature titanium alloy bars. These properties determine the behavior and performance of the high-temperature titanium alloy bars under different environmental conditions. These material properties are collected by testing equipment such as physical property testing equipment, chemical property testing equipment, and mechanical property testing equipment.

[0034] A three-dimensional digital twin model is a virtual, fully corresponding 3D digital model of the aforementioned high-temperature titanium alloy bar. It not only accurately simulates the geometry and dimensions of the bar, achieving high-precision shape reproduction by integrating 3D scanning data, but also incorporates material properties, enabling the 3D digital twin model to realistically reflect the physical, chemical, and mechanical behavior of the high-temperature titanium alloy bar under different environmental conditions. Furthermore, this 3D digital twin model possesses real-time interactivity and dynamic updating capabilities, allowing for real-time synchronization and interactive feedback with various data from the actual high-temperature titanium alloy bar during production and use.

[0035] Optionally, the 3D scan data may include surface point cloud data and internal structure data, etc.

[0036] Optionally, material properties may include mechanical properties, thermophysical parameters, and microstructure data.

[0037] The following section details how an electronic device constructs a three-dimensional digital twin model of a high-temperature titanium alloy rod based on the collected three-dimensional scanning data and material properties: In some embodiments, the electronic device constructs a three-dimensional digital twin model of the high-temperature titanium alloy bar based on the collected three-dimensional scanning data and material properties of the high-temperature titanium alloy bar. This may include: the electronic device collecting surface point cloud data and internal structure data of the high-temperature titanium alloy bar and determining them as three-dimensional scanning data; the electronic device collecting mechanical properties, thermophysical parameters, and microstructure data of the high-temperature titanium alloy bar and determining them as material properties; and the electronic device modeling the high-temperature titanium alloy bar based on the three-dimensional scanning data and material properties to obtain a three-dimensional digital twin model.

[0038] In constructing a three-dimensional digital twin model, the electronic device first uses a laser 3D scanner and a structured light 3D scanner to scan the high-temperature titanium alloy bar, obtaining surface point cloud data. This surface point cloud data can accurately describe the geometry, size, and contour of the bar's surface. Simultaneously, an industrial CT scanner uses X-ray tomography to acquire internal structural data of the high-temperature titanium alloy bar, including the distribution of internal defects such as pores, cracks, and inclusions, as well as the hierarchical structure of different microstructures. Then, the electronic device integrates the surface point cloud data and the internal data to form three-dimensional scan data, providing rich information for a comprehensive understanding of the geometric characteristics of the high-temperature titanium alloy bar.

[0039] Next, the electronic device uses mechanical property testing equipment (such as a universal testing machine) to conduct tensile, compression, and bending tests on the high-temperature titanium alloy bar to obtain mechanical properties, including tensile strength, yield strength, and fracture toughness. It then uses physical property testing equipment (such as a thermal expansion meter and thermal conductivity meter) to measure thermophysical parameters, including the coefficient of thermal expansion and thermal conductivity. Finally, it uses chemical property testing equipment (such as a metallographic microscope and scanning electron microscope) to observe and analyze the microstructure data of the high-temperature titanium alloy bar, including grain size, phase composition, and crystal orientation. Finally, the electronic device comprehensively determines the material properties based on the mechanical properties, thermophysical parameters, and microstructure data.

[0040] Finally, the electronic device integrates and analyzes the collected 3D scan data and material property data. Using computer graphics, numerical simulation, and other technologies, a geometric model of the high-temperature titanium alloy bar is established based on the 3D scan data, accurately reproducing its external shape and internal structure. Simultaneously, material properties are assigned to each part of the geometric model, ensuring that the model not only has an accurate geometric shape but also simulates the physical, chemical, and mechanical behavior of the material under different environmental conditions. In this way, a 3D digital twin model highly consistent with the aforementioned high-temperature titanium alloy bar is constructed.

[0041] It should be noted that there are no time restrictions on the timing of electronic devices acquiring 3D scanning data and material properties.

[0042] Optionally, before step 101, the method may further include: an electronic device heating and holding the initial high-temperature titanium alloy rod in a temperature range of (Tβ-50)℃ to (Tβ-30)℃ to obtain a high-temperature titanium alloy rod; wherein, Tβ represents the β-phase transformation temperature of the titanium alloy material.

[0043] Among them, the initial high-temperature titanium alloy rod is a rod-shaped metal material with a certain diameter and length, which is made of titanium as the main alloying element and has no treatment.

[0044] In determining the high-temperature titanium alloy rod material for electronic devices, an initial high-temperature titanium alloy rod material can be obtained first. This initial rod material is then heated and held at a temperature range of (Tβ-50)℃ to (Tβ-30)℃ to obtain the final high-temperature titanium alloy rod material. It should be noted that the initial high-temperature titanium alloy rod material within this temperature range is in the α+β two-phase region, with a relatively high proportion of the β phase. The purpose of heating is to provide energy to the initial high-temperature titanium alloy rod material, enabling its atoms to have sufficient mobility, thereby causing changes in its microstructure. The purpose of holding the temperature is to ensure uniform internal temperature of the initial high-temperature titanium alloy rod material, ensuring that the entire rod material can undergo sufficient microstructural transformation. In other words, after heating and holding, the microstructure and properties of the initial high-temperature titanium alloy rod material will change, resulting in a high-temperature titanium alloy rod material with superior performance.

[0045] Furthermore, heating and holding the initial high-temperature titanium alloy bar within a temperature range of (Tβ-50)℃ to (Tβ-30)℃ is a key prerequisite for ensuring the uniformity of the microstructure and the final mechanical properties of the initial high-temperature titanium alloy bar during subsequent die forming. This ensures the uniformity of the microstructure of the subsequent target irregular ring forging under triaxial stress during the entire die forming process, avoiding problems such as clear and semi-clear crystals in the forging, and thus guaranteeing the mechanical properties of the target irregular ring forging.

[0046] Step 102: Obtain real-time deformation data of the high-temperature titanium alloy bar formed by the ring forging forming equipment.

[0047] Among them, the ring forging forming equipment is a device that achieves integral forming of high-temperature titanium alloy bars through local deformation accumulation.

[0048] Real-time deformation data refers to at least one of the following data collected in real time during the forming process of irregular ring forging: geometric deformation data, mechanical response data, temperature field data, force-energy parameters, defect early warning data, and micro-evolution data.

[0049] Optionally, the ring forging forming equipment may include at least: die forming equipment, upsetting equipment, punching equipment, frame reaming equipment, and circular rolling equipment.

[0050] The die-forming equipment is a closed-type die forging device consisting of a die-forming mold, a lower anvil, and an upper anvil with a first punch. It uses dynamic hammering to fill a shaped cavity with a high-temperature titanium alloy bar. Understandably, the lower end face of the die-forming equipment rests on the lower anvil, and the closed cavity shape formed by the combination of the lower anvil, die-forming mold, and upper anvil matches the shape of the target shaped ring forging. The vertical height of the first punch matches the height of the internal cavity of the die-forming mold, and the diameter of the upper end face of the first punch is larger than the diameter of the lower end face of the first punch.

[0051] Upsetting equipment is an open forging equipment that reduces the height and increases the diameter of high-temperature titanium alloy bars through axial compression.

[0052] A punching machine is an axial loading device that uses a second punch to perform penetration processing in the central area of ​​a high-temperature titanium alloy bar, which can produce a high-temperature titanium alloy perforated bar.

[0053] The frame-type hole enlarging equipment is a rotary forming device that expands the ring diameter of high-temperature titanium alloy perforated rods through radial rolling of frame rollers and cooperation with a mandrel.

[0054] A circular rolling mill is a continuous rolling mill that uses a combination of flat and vertical rolls to precisely form circular cross-section rings.

[0055] Optionally, when the ring forging forming equipment includes a die forming equipment, an upsetting equipment, a punching equipment, a reaming machine, and a circular rolling equipment, the process of the electronic equipment controlling the ring forging forming equipment to perform forming processing on the high-temperature titanium alloy bar is as follows: the electronic equipment sequentially controls the upsetting equipment, the punching equipment, the reaming machine, the circular rolling equipment, and the die forming equipment to perform corresponding processing on the high-temperature titanium alloy bar, thereby achieving the successful forming of the subsequent target irregular-shaped ring forging.

[0056] Specifically, electronic equipment controls an upsetting device to reduce the height and increase the diameter of a high-temperature titanium alloy bar A through axial compression, resulting in an upset high-temperature titanium alloy bar B. Next, an electronic punching device is controlled to perform penetration processing in the central area of ​​the high-temperature titanium alloy bar B using a second punch, generating a high-temperature titanium alloy perforated bar A'. Then, an electronic reaming device is controlled to achieve rotational forming of the ring diameter of the high-temperature titanium alloy perforated bar A' through radial rolling with a mandrel, resulting in a high-temperature titanium alloy perforated bar B'. Finally, an electronic circular rolling device is controlled to achieve continuous and precise forming of the circular cross-section ring corresponding to the high-temperature titanium alloy perforated bar B' through a combination of flat and vertical rolls. Rolling yields a high-temperature titanium alloy perforated rod C'. Finally, the high-temperature titanium alloy perforated rod C' is formed using a die-forming device. Specifically, the high-temperature titanium alloy perforated rod C' is placed inside the die-forming mold, and the first punch is positioned above the second high-temperature titanium alloy billet for alignment and positioning. Under alignment, the upper hammer anvil is pressed down onto the upper end face of the die-forming mold, so that the high-temperature titanium alloy perforated rod C' is formed within the closed cavity formed by the lower hammer anvil, the die-forming mold, and the upper hammer anvil. Since the diameter of the upper end face of the first punch is larger than the diameter of the lower end face of the first punch, the diameter reduction of the high-temperature titanium alloy perforated rod C' can be effectively achieved.

[0057] It should be noted that during the forming process, the high-temperature titanium alloy perforated rod C' is processed and formed step by step by using a die-shaped forming operation. The upper hammer anvil and the first punch on the upper hammer anvil are controlled in sequence with the die-shaped forming mold and the lower hammer anvil. The entire forming process does not rely on a special-shaped rolling mill and special-shaped rolling mold, which can effectively improve the processing efficiency and forming effect of the target special-shaped ring forging and reduce the mold cost of the preparation process.

[0058] Understandably, in order to ensure the precise forming of the target irregular ring forging, during the forming process of the ring forging equipment controlled by electronic equipment on the high-temperature titanium alloy bar, the high-temperature titanium alloy bar A, high-temperature titanium alloy bar B, high-temperature titanium alloy perforated bar A', high-temperature titanium alloy perforated bar B' and high-temperature titanium alloy perforated bar C' are always heated and held at a temperature range of (Tβ-50)℃ to (Tβ-30)℃.

[0059] In some embodiments, when the ring forging forming equipment is a die forming equipment, the real-time deformation data may include: geometric deformation data (such as three-dimensional cavity filling rate, axial compression, radial flow velocity field, flash thickness distribution, etc.), mechanical response data (such as mold closing impact force, mold parting surface pressure, material flow resistance gradient, etc.), temperature field data (such as cavity internal temperature distribution, adiabatic temperature rise hot spot, etc.), and defect early warning data (such as fold defect acoustic emission signal and surface crack, etc.).

[0060] In some embodiments, when the ring forging forming equipment is an upsetting equipment, the real-time deformation data may include: geometric deformation data (such as the diameter change, axial compression, and radial widening of high-temperature titanium alloy bars), temperature field data (such as core temperature and surface temperature), mechanical response data (such as real-time deformation resistance and strain rate), and micro-evolution data (such as grain orientation).

[0061] In some embodiments, when the ring forging forming equipment is a punching equipment, the real-time deformation data may include: geometric deformation data (such as the displacement of the second punch in the punching equipment relative to the high-temperature titanium alloy bar, the hole diameter expansion of the high-temperature titanium alloy bar, the material flow velocity field, etc.), force-energy parameters (such as the axial pressure of the punch, the radial extrusion pressure, the punching work, etc.), and temperature field data (such as the hole wall temperature gradient, and the contact surface temperature between the high-temperature titanium alloy bar and the second punch, etc.).

[0062] In some embodiments, when the ring forging forming equipment is a reaming machine, the real-time deformation data may include: geometric deformation data (such as radial reaming amount, wall thickness reduction rate, ellipticity deviation, etc.), mechanical response data (such as reaming roll force, mandrel axial tension, torque fluctuation, etc.), temperature field data (such as temperature difference between the inner and outer walls of the ring, instantaneous temperature rise in the deformation zone, etc.), and micro-evolution data (such as dynamic recrystallization acoustic characteristics and texture evolution, etc.).

[0063] In some embodiments, when the ring forging forming equipment is a circular rolling equipment, the real-time deformation data may include: geometric deformation data (such as compression in the thickness direction, widening in the width direction, elongation in the length direction, cross-sectional shape distortion, etc.), mechanical response data (such as strain rate field), temperature field data (such as temperature gradient on the surface of the rolled piece, transient temperature rise in the roll contact area, etc.), and micro-evolution data (such as dynamic recrystallization acoustic emission characteristics), etc.

[0064] Step 103: Update the model parameters of the three-dimensional digital twin model in real time based on the real-time deformation data; and generate equipment adjustment instructions based on the model parameters. The equipment adjustment instructions are used to instruct the ring forging forming equipment to adjust according to the equipment adjustment parameters.

[0065] Among them, the model parameters are digital variables that describe the geometry, material state and process conditions of high-temperature titanium alloy bars. The core function of these model parameters is to map the deformation state of the high-temperature titanium alloy bar entity in the physical world in real time.

[0066] The equipment adjustment parameters are control commands generated based on model parameter analysis and directly applied to the ring forging forming equipment. The core objective of these equipment adjustment parameters is to eliminate the deviation between actual processing and the theoretical model.

[0067] In step 103, since abnormalities inevitably occur during the forming process of high-temperature titanium alloy bars by the ring forging forming equipment, the electronic equipment, after acquiring real-time deformation data, can update the model parameters of the three-dimensional digital twin model in real time based on this data. Then, it calculates the updated model parameters to obtain equipment adjustment parameters and generates corresponding equipment adjustment commands. This allows the adjusted ring forging forming equipment to continue forming the high-temperature titanium alloy bars more efficiently and accurately. Furthermore, the entire process, based on the model parameters of the three-dimensional digital twin model, allows for timely adjustment of the equipment parameters of the ring forging forming equipment, effectively shortening the production cycle.

[0068] It should be noted that since the electronic equipment sequentially controls the upsetting equipment, punching equipment, reaming equipment, circular rolling equipment and die forming equipment to process the high-temperature titanium alloy bars, when different equipment processes the high-temperature titanium alloy bars, real-time deformation data can be collected for the processing of each equipment, and subsequent steps 103-104 can be executed.

[0100] Step 104: The adjusted ring forging equipment is used to continue forming the high-temperature titanium alloy bar to obtain the target anisotropic ring forging.

[0101] In step 104, the adjusted ring forging forming equipment can more efficiently and accurately continue forming the high-temperature titanium alloy bar, obtaining a target irregular ring forging with a higher forming quality. Furthermore, the entire process requires no manual intervention. Based on a three-dimensional digital twin model corresponding to the physical high-temperature titanium alloy bar, real-time and accurate correction of the bar during processing can be achieved, saving time and effort and effectively improving the processing efficiency of the target irregular ring forging.

[0102] For example, in the case where the target irregular ring forging is a "flared" irregular ring forging, such as Figure 2 The image shown is a schematic diagram illustrating a scenario of punching a high-temperature titanium alloy rod B according to an embodiment of this application. From... Figure 2 As can be seen from the above: the upsetting equipment, controlled and adjusted by the electronic equipment, reduces the height and increases the diameter of the high-temperature titanium alloy bar A through axial compression, resulting in the upset high-temperature titanium alloy bar B; then the punching equipment, controlled and adjusted by the electronic equipment, uses the second punch to perform penetration processing in the central area of ​​the high-temperature titanium alloy bar B, generating a high-temperature titanium alloy perforated bar A'.

[0103] For example, combined Figure 2 ,like Figure 3 The diagram shown is a schematic representation of a scenario involving the reaming of a high-temperature titanium alloy perforated bar B' according to an embodiment of this application. The reaming equipment, controlled and adjusted by electronic equipment, achieves rotational forming of the ring diameter of the high-temperature titanium alloy perforated bar A' through radial rolling of the reamer rollers and cooperation with the mandrel, resulting in the high-temperature titanium alloy perforated bar B'. Then, the adjusted circular rolling equipment, controlled by electronic equipment, continuously rolls a circular section ring corresponding to the high-temperature titanium alloy perforated bar B' through a combination of flat and vertical rollers, precisely forming the ring, resulting in the desired ring shape. Figure 4 The high-temperature titanium alloy perforated rod C' shown is shown.

[0104] For example, combined Figure 3 and Figure 4 ,like Figure 5 The image shown is a schematic diagram illustrating the forming process of a high-temperature titanium alloy perforated rod C' according to an embodiment of this application; as shown... Figure 6 The image shown is a simulation diagram illustrating the forming process of a high-temperature titanium alloy perforated rod C' according to an embodiment of this application. Figure 5It can be seen that the electronic device controls the high-temperature titanium alloy piercing rod C' to be placed on the lower hammer anvil, and controls the mold forming die to press down, so that the high-temperature titanium alloy piercing rod C' is placed inside the mold forming die. From Figure 6 As can be seen from (a)-(d) in the diagram: the electronic device controls the first punch on the upper hammer anvil to be positioned above the second high-temperature titanium alloy billet for alignment and positioning. Under alignment, the upper hammer anvil is controlled to press down as a whole onto the upper end face of the die forming mold, so that the high-temperature titanium alloy piercing rod C' is formed in the closed mold cavity formed by the combination of the lower hammer anvil, the die forming mold, and the upper hammer anvil, resulting in... Figure 7 The image shows a "trumpet-shaped" irregular ring forging.

[0105] exist Figures 2-6 In the process shown, the high-temperature titanium alloy perforated bar C' is processed step by step through the die-forming operation, controlling the upper hammer anvil and the first punch on the upper hammer anvil, combined with the die-forming mold and the lower hammer anvil, to obtain the target irregular ring forging. The whole process does not rely on irregular rolling mills and irregular rolling dies, which simplifies the titanium alloy forming process and effectively reduces the mold cost.

[0106] It should be noted that the "trumpet-shaped" ring forging has a strength of approximately 670 MPa and a plasticity of approximately 22% at 650℃; and a strength of approximately 600 MPa and a plasticity of approximately 13% at 700℃. The high-magnification microstructure of this "trumpet-shaped" ring forging mainly consists of equiaxed and / or elongated primary α phases distributed on a β-transformed matrix. All primary β grain boundaries should be broken, and the volume fraction of the equiaxed primary α phase should be 5%–25%. Its excellent overall performance ensures that the dimensions, properties, and quality of this "trumpet-shaped" ring forging meet the forging acceptance requirements.

[0107] The following section details the process by which a ring forging forming equipment, after adjustments to electronic control, further processes high-temperature titanium alloy bars to obtain the desired anisotropic ring forgings: Optionally, the ring forging forming equipment controlled and adjusted by electronic equipment continues to perform forming processing on the high-temperature titanium alloy bar to obtain the target irregular ring forging. This may include: the ring forging forming equipment controlled and adjusted by electronic equipment continues to perform forming processing on the high-temperature titanium alloy bar to obtain the initial target irregular ring forging; the electronic equipment performs rework, heat treatment, physical and chemical testing, rough machining and ultrasonic flaw detection operations on the initial target irregular ring forging to obtain the target irregular ring forging.

[0108] Rework refers to the process of repairing defects or adjusting the dimensions of the initial target irregular-shaped ring forging. During the forging process, defects such as cracks, folds, and dimensional discrepancies may occur. The purpose of rework is to eliminate these defects through methods such as welding, grinding, and correction, so that the target irregular-shaped ring forging meets the specified quality requirements.

[0109] Heat treatment refers to the process of altering the internal microstructure of an initial target irregular-shaped ring forging through heating, holding, and cooling, thereby improving its mechanical and machinability. Optionally, heat treatment may include annealing, normalizing, quenching, and tempering. For initial target irregular-shaped ring forgings, heat treatment can eliminate internal stress and improve the strength, hardness, and toughness of titanium alloy materials.

[0110] Physicochemical testing refers to the process of testing the physical and chemical properties of the initial target irregular-shaped ring forging. This testing may include tensile testing, impact testing, hardness testing, metallographic analysis, etc., to evaluate the strength, plasticity, toughness, hardness, and other mechanical properties of the initial target irregular-shaped ring forging, as well as whether the chemical composition and microstructure of the titanium alloy material meet the requirements.

[0111] Rough machining refers to the preliminary machining of an initial target irregular-shaped ring forging to bring it closer to its final shape and size. Optionally, rough machining may include operations such as turning, milling, and drilling, with the aim of removing excess material from the surface of the initial target irregular-shaped ring forging.

[0112] Ultrasonic testing is a non-destructive testing method that utilizes the propagation characteristics of ultrasonic waves in titanium alloy materials to detect internal defects in an initial target irregular-shaped ring forging. By emitting ultrasonic waves and receiving the reflected signals, it is possible to determine whether defects such as cracks, porosity, and inclusions exist inside the initial target irregular-shaped ring forging, and to determine the location and size of the defects.

[0113] After determining the initial target irregular-shaped ring forging for electronic equipment, some minor defects may still exist. Therefore, the rework, heat treatment, physical and chemical testing, rough machining, and ultrasonic testing operations performed on the initial target irregular-shaped ring forging are important steps to ensure the quality, performance, and safety of the forging, thereby effectively improving material utilization. These operations are interrelated and together constitute the complete processing flow of the irregular-shaped ring forging from its initial state to the final product.

[0114] In this embodiment, a three-dimensional digital twin model of the high-temperature titanium alloy bar is constructed based on the collected three-dimensional scanning data and material properties. Real-time deformation data of the high-temperature titanium alloy bar during forming processing by a ring forging equipment is acquired. The model parameters of the three-dimensional digital twin model are updated in real time based on the deformation data. Equipment adjustment instructions are generated based on the model parameters, instructing the ring forging equipment to adjust according to the equipment adjustment parameters. The adjusted ring forging equipment is then controlled to continue forming processing of the high-temperature titanium alloy bar to obtain the target irregular-shaped ring forging. This method, by constructing a three-dimensional digital twin model of the high-temperature titanium alloy bar, achieves intelligent control of the forming process of the high-temperature titanium alloy bar. The entire process requires no manual intervention and can effectively improve the processing efficiency and forming effect of the target irregular-shaped ring forging.

[0115] To better understand the embodiments of this application, the low-magnification and high-magnification microstructures of the target irregular ring forging (such as a "trumpet-mouth" irregular ring forging) are described in detail below: For example, such as Figure 8a The image shown is a low-magnification photograph of the microstructure of the "trumpet-shaped" irregular ring forging provided in an embodiment of this application. From... Figure 8a As can be seen from the data, the corroded surface of the low-magnification specimen must not have any visually visible cracks, shrinkage cavities, porosity, folds, inclusions, segregation, or other defects that affect its use. Segregated bright streaks, bright patches, β spots, hard α phase and soft α phase inclusions, and high-density inclusions are not allowed. The low-magnification microstructure of the specimen should be fine, indistinct crystals; obvious, visually visible, clear grains are not permitted. The low-magnification microstructure should conform to GJB2220A-2018. Figure 1 Requirements for Level 1 to Level 3.

[0116] For example, such as Figure 8b The image shown is a low-magnification photograph of the microstructure of the "trumpet-shaped" irregular ring forging provided in an embodiment of this application. From... Figure 8b It can be seen that the high-magnification tissues are all processed tissues in the α+β region, which conforms to GJB2220A-2018. Figure 3 Grade 4, primary α phase volume fraction is 20%, and tissue morphology meets standard requirements.

[0117] In summary, combining Figure 8a and Figure 8b It can be seen that the dimensions, performance, and quality of the "trumpet-shaped" irregular ring forging meet the design requirements.

[0118] The room temperature tensile properties and high temperature tensile properties of the "trumpet-shaped" irregular ring forgings are described in detail below: For example, Table 1 is a table of room temperature tensile properties of "trumpet mouth" shaped ring forgings.

[0119] Table 1: Rm represents tensile strength, which characterizes the maximum stress that titanium alloy materials can withstand in a tensile test, and the unit is megapascal (MPa). Rp0.2 represents the 0.2% yield strength, which characterizes the stress that a titanium alloy material can withstand when it undergoes 0.2% plastic deformation, and is measured in megapascals (MPa). A represents the elongation after fracture, which characterizes the ratio of the total deformation of the gauge length segment to the original gauge length after tensile fracture of the titanium alloy material, expressed as a percentage. Z represents the reduction of area, which characterizes the ratio of the area of ​​the reduced cross-section to the original cross-sectional area after tensile fracture of a titanium alloy material, expressed as a percentage. HBW represents Brinell hardness, which characterizes the hardness value of titanium alloy materials.

[0120] It should be noted that Table 1 shows the results of two tensile property tests on titanium alloy materials at room temperature and the corresponding acceptance criteria.

[0121] As can be seen from Table 1, the results of the two tensile property tests of the titanium alloy material at room temperature both met or exceeded the given acceptance criteria, indicating that the titanium alloy material exhibits good performance in terms of tensile strength, yield strength, elongation after fracture, reduction of area, and hardness, and meets the application requirements.

[0122] For example, Table 2 is a table of high-temperature tensile properties of "trumpet mouth" shaped ring forgings.

[0123] Table 2: It should be noted that Table 2 shows the tensile property test results of titanium alloy materials at 650℃ and 700℃, as well as the corresponding acceptance criteria.

[0124] As shown in Table 2, the tensile properties of the titanium alloy at 650℃ and 700℃ both meet or exceed the given acceptance criteria. The titanium alloy exhibits excellent performance in terms of tensile strength, 0.2% yield strength, elongation after fracture, and reduction of area. Particularly noteworthy is its ability to maintain high strength and ductility even at high temperatures (700℃), demonstrating its superior high-temperature performance. Therefore, this titanium alloy is suitable for applications requiring high temperatures and high stress.

[0125] In summary, the intelligent manufacturing method for titanium alloy shaped ring forgings provided in this application can solve the complex problems encountered in the production process of Ti65 alloy "trumpet-shaped" ring forgings. It can also quickly and efficiently produce Ti65 alloy "trumpet-shaped" ring forgings, and can significantly improve the strength and plasticity of Ti65 alloy "trumpet-shaped" ring forgings. It does not require manual intervention, nor does it require shaped rolling mills and shaped rolling dies. It can effectively improve the processing efficiency and forming effect of the target shaped ring forgings and reduce the mold cost in the manufacturing process.
