TECHNICAL FIELD

[0002] Titanium alloy has the advantages of high specific strength, good corrosion resistance and good thermal strength, and can greatly reduce the product quality and further improve the thrust-to-weight ratio of engines in the field of aerospace. Among them, Ti65 alloy is a multi-element composite reinforced near-alpha type high-temperature titanium alloy designed by China itself, which has excellent comprehensive performance and high thermal strength, oxidation resistance and thermal stability at 650°C.

[0003] However, the forming process of high-temperature titanium alloy has poor performance, and smelting, forging and welding are difficult. The traditional titanium alloy forming preparation method mainly relies on special-shaped rolling mills and matching dies (such as special-shaped rolling dies) to implement. The specific process is to apply pressure through a special-shaped rolling mill, and to force the titanium alloy blank to deform plastically by using the specific shape of the special-shaped rolling die to preliminarily form a target special-shaped ring forge piece (such as an S-bent special-shaped ring forge piece). However, this titanium alloy forming preparation method has the following significant shortcomings: the machining efficiency of the target special-shaped ring forge piece is low due to the complexity of the titanium alloy forming process, the forming effect of the target special-shaped ring forge piece is poor due to the insufficient tonnage of the special-shaped rolling mill, and the die cost is high.

[0004] Therefore, how to effectively improve the machining efficiency and forming effect of the target special-shaped ring forge piece and reduce the die cost of the intelligent preparation process has become a problem to be solved. SUMMARY

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in detail with the drawings in the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0021] To better understand the embodiments of the present application, first, the application scenarios of the intelligent preparation method of a titanium alloy special-shaped ring forge piece provided by the embodiments of the present application will be described in detail. Since the intelligent preparation method of titanium alloy special-shaped ring forgings is suitable for fields with high requirements on material performance, in addition to being applied in the field of aerospace, it can also be applied in the fields of energy (such as petroleum, natural gas and nuclear energy, for manufacturing high-pressure containers, pipeline connections and reactor components, etc.), chemical industry and marine engineering (for manufacturing corrosion-resistant pipes, valves and pump bodies, etc.), medical devices (for manufacturing artificial joints, dental implants and surgical instruments, etc.), and automobile manufacturing (for manufacturing high-performance engine components, suspension systems and transmission systems, etc.), and other fields with extremely high requirements on the precision of parts.

[0022] It should be noted that the execution subject involved in the embodiments of the present application can be an intelligent preparation device of titanium alloy special-shaped ring forgings, or an electronic device. Optionally, the electronic device can include a computer, a mobile terminal, an electronic assembly device, and an electrical equipment production device.

[0023] The intelligent preparation method of titanium alloy special-shaped ring forgings provided by the embodiments of the present application will be described in detail below taking an electronic device as an example: Figure 1 is a flowchart of the intelligent preparation method of titanium alloy special-shaped ring forgings provided by the embodiments of the present application. As shown in Figure 1 , the method includes the following steps 101-104.

[0024] Step 101, place the titanium alloy bar in the tire mold forming die, and control the lower plane of the first upper hammer anvil to press down to the upper end face of the tire mold forming die to preliminarily form the titanium alloy bar to obtain a titanium alloy blank; wherein the lower end face of the tire mold forming die is placed on the lower hammer anvil, and the closed die cavity formed by the combination of the lower hammer anvil, the tire mold forming die and the second upper hammer anvil with the punch matches the shape of the target special-shaped ring forging.

[0025] The titanium alloy bar is a rod-shaped metal material with a certain diameter and length taking titanium as the main alloying element. The titanium alloy bar is also the initial processing raw material, which is gradually changed into a forging with a target shape (i.e. a target special-shaped ring forging such as an S-bent special-shaped ring forging) through a series of titanium alloy forming operations.

[0026] The tire mold forming die is a die for forming the titanium alloy bar. The tire mold forming die has a specific shape and structure, and the shape of the internal cavity of the tire mold forming die determines the shape of the blank after the preliminary forming of the titanium alloy bar, that is, the shape of the closed die cavity formed by the combination of the tire mold forming die, the lower hammer anvil and the second upper hammer anvil with the punch matches the shape of the target special-shaped ring forging. It should be noted that the tire mold forming die provides space and constraints for the deformation of the titanium alloy bar, guides the flow of the material, and makes the titanium alloy bar gradually approach the shape of the target special-shaped ring forging.

[0027] The first upper anvil is an upper tool used to apply pressure to titanium alloy bars. This first upper anvil has a flat lower surface and, under the control of electronic equipment, can move downwards above a forming die, pressing the lower surface against the upper end face of the forming die. This applies pressure to the titanium alloy bar placed within the forming die, causing plastic deformation and achieving preliminary forming. It should be noted that the first upper anvil needs sufficient strength and rigidity to ensure it does not deform under high pressure. Furthermore, the flatness of the lower surface of the first upper anvil has a significant impact on the forming quality of the titanium alloy.

[0028] The lower anvil is a supporting component throughout the titanium alloy forming process. The lower end face of the forming die rests on the upper surface of the lower anvil. Therefore, the lower anvil provides stable support for the forming die, withstanding pressure from the first upper anvil, the deformation of the titanium alloy bar, and the forming die itself. It should be noted that the lower anvil also needs to possess high strength and good stability to ensure that it does not move or break during the entire titanium alloy forming process, thus guaranteeing the smooth progress of the forming process.

[0029] The second upper hammer anvil is an upper tool used in subsequent processing steps. It should be noted that the second upper hammer anvil is used to further precisely shape the aforementioned titanium alloy billet, enabling the titanium alloy billet to meet the shape and size requirements of the target irregular ring forging.

[0030] The punch is a component mounted on the second upper anvil and is a key tool in the titanium alloy forming process. The shape of the punch is designed according to the internal shape of the target irregular ring forging. When the second upper anvil moves downwards above the die forming mold, the punch can embed itself into the interior of the titanium alloy billet, applying pressure to the billet and causing it to flow and deform according to the shape of the punch. This forms a portion within the closed die cavity that conforms to the internal shape of the target irregular ring forging. Working together with the lower anvil, the die forming mold, and the second upper anvil, it completes the precise forming of the target irregular ring forging.

[0031] In conjunction with step 101, for example, as follows Figure 2a The image shown is a schematic diagram illustrating a scenario for determining a titanium alloy billet according to an embodiment of this application. From... Figure 2aAs can be seen: in the process of blanking, the electronic device first acquires the titanium alloy bar and places the acquired titanium alloy bar in the tire mold forming die. Then, in the process of processing the titanium alloy bar, the electronic device can control the first upper anvil to move downward in the upward direction of the tire mold forming die, apply pressure to the titanium alloy bar placed in the tire mold forming die, cause the titanium alloy bar to plastically deform, realize the preliminary forming of the titanium alloy bar, and specifically control the lower plane of the first upper anvil to press down to the upper end face of the tire mold forming die to preliminarily form the titanium alloy bar to obtain a titanium alloy blank. At this time, the titanium alloy blank is in contact with the upper end face of the tire mold forming die, which can effectively ensure the correct position and preliminary shape of the titanium alloy blank in the tire mold forming die for subsequent continuous processing.

[0032] It can be understood that the first upper anvil and the second upper anvil can be the same or different, and are not specifically limited here.

[0033] In some embodiments, before the electronic device acquires the titanium alloy bar and places it in the tire mold forming die, the method can further include: the electronic device heats and holds the initial titanium alloy bar at a temperature range of (Tβ-50) to (Tβ-30) to obtain the titanium alloy bar; wherein Tβ represents the β phase transition temperature of the titanium alloy material.

[0034] The initial titanium alloy bar is a rod-shaped metal material with a certain diameter and length that has not been treated in any way and has titanium as the main alloying element.

[0035] In the process of determining the titanium alloy bar, the electronic device can first acquire the initial titanium alloy bar, and then heat and hold the acquired initial titanium alloy bar at a temperature range of (Tβ-50) to (Tβ-30) to obtain the titanium alloy bar. It should be noted that the initial titanium alloy bar in the above temperature range is in the α+β two-phase region, and the proportion of the β phase is relatively high. The purpose of heating is to provide energy to the initial titanium alloy bar so that the atoms of the initial titanium alloy bar have sufficient activity to change the microstructure; the purpose of holding is to make the internal temperature of the initial titanium alloy bar uniform to ensure that the entire bar can fully undergo organizational transformation. That is, after heating and holding, the microstructure and properties of the initial titanium alloy bar will change, and a titanium alloy bar with better performance will be obtained.

[0036] Furthermore, heating and holding the initial 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 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.

[0037] Optionally, after heating and heat preservation, the method may further include: an electronic device upsetting the initial titanium alloy bar to obtain a titanium alloy bar.

[0038] Upsetting process reduces the height and increases the cross-sectional area of ​​the initial titanium alloy bar through axial compression.

[0039] In this way, after the initial titanium alloy rod is upset, the electronic device can achieve the initial shaping of the initial titanium alloy rod and obtain the titanium alloy rod for further processing.

[0040] Step 102: Control the punch on the second upper hammer anvil to be positioned above the titanium alloy billet for alignment and positioning, and obtain the positioning result.

[0041] Combining step 102 and Figure 2a For example, such as Figure 2b The image shown is a schematic diagram illustrating a scenario for aligning and positioning a titanium alloy billet, as provided in an embodiment of this application. From... Figure 2b As can be seen, during the alignment and positioning process of the titanium alloy billet, the electronic equipment first controls the punch on the second upper hammer anvil to be positioned above the titanium alloy billet, and then controls the punch to move above the titanium alloy billet to achieve alignment and positioning. This allows the system to determine whether the relative position between the punch and the titanium alloy billet is accurate, and obtain the corresponding positioning result. It should be noted that accurate alignment and positioning can avoid the punch applying uneven force to the titanium alloy billet during the die forming process, thereby reducing the concentration of internal stress in the titanium alloy billet and lowering the possibility of defects such as cracks and folds. In addition, by precisely controlling the relative position between the punch and the titanium alloy billet, it can be ensured that the dimensions, performance, and quality of the processed titanium alloy product (i.e., the target irregular ring forging) meet the design requirements.

[0042] The following section details the process of aligning and positioning the punch on the second upper hammer anvil above the titanium alloy billet using electronic control, and the resulting positioning information: In some embodiments, the electronic device controls the punch on the second upper anvil to be positioned above the titanium alloy blank for alignment positioning to obtain a positioning result, which can include: the electronic device controls the punch to be positioned above the titanium alloy blank; the electronic device determines a center point of a lower end surface of the punch as a first center point; and determines a center point of an upper end surface of the titanium alloy blank as a second center point; the electronic device calculates a line between the first center point and the second center point; the electronic device detects a perpendicularity deviation between the line and an upper end surface of the tire mold forming die, and determines the positioning result according to the perpendicularity deviation.

[0043] The line is used to reflect the relative relationship between the direction of the punch force and the center position of the titanium alloy blank, and is an important basis for judging the accuracy of the alignment positioning.

[0044] The perpendicularity deviation is an index of the allowed variation range of the actual direction between the measured element (i.e., the line) and the reference element (i.e., the upper end surface of the tire mold forming die) deviating from the ideal vertical direction (i.e., 90° angle), which ensures that the line and the upper end surface maintain a strict orthogonal relationship. The size of the perpendicularity deviation directly reflects whether the alignment positioning of the punch and the titanium alloy blank is vertical. If there is a deviation, it may cause uneven stress on the titanium alloy blank during subsequent forming processing, thereby causing defects such as deformation and cracking.

[0045] During the alignment positioning of the titanium alloy blank by the electronic device, the punch is first controlled to move and be positioned above the titanium alloy blank; then, the geometric center of the lower end surface (i.e., the plane close to the titanium alloy blank) of the punch is identified and positioned, and is determined as the first center point, and the geometric center of the upper end surface (i.e., the plane close to the punch) of the titanium alloy blank is identified and positioned, and is determined as the second center point; subsequently, the electronic device calculates the line between the first center point and the second center point, and detects the perpendicularity deviation between the line and the upper end surface of the tire mold forming die, and then determines the positioning result. It should be noted that the entire alignment positioning process can ensure accurate alignment positioning between the punch and the titanium alloy blank, providing high-quality initial conditions for subsequent tire mold forming processing. In addition, accurate alignment positioning can improve the machining precision of the target special-shaped ring forging, reduce the scrap rate and production cost, and ensure that the size, performance and quality of the target special-shaped ring forging meet the design requirements.

[0046] Alternatively, since the upper end surface of the tire mold forming die is parallel to the lower end surface of the tire mold forming die, the electronic device can also detect the perpendicularity deviation between the line and the lower end surface of the tire mold forming die, and then determine the positioning result.

[0047] It should be noted that the timing of the electronic device determining the first center point and the second center point is not limited.

[0048] In step 103, the electronic device controls the punch to continue to press down according to the positioning result, and detects the embedding depth of the punch relative to the titanium alloy blank in real time during the continuous pressing.

[0049] The embedding depth refers to the distance of the part of the punch pressed into the titanium alloy blank in the vertical direction.

[0050] In step 103, the electronic device can control the punch to continue to press down according to the positioning result, and detect the embedding depth of the punch relative to the titanium alloy blank in real time during the continuous pressing. It should be noted that the entire pressing action can continuously apply pressure to the titanium alloy blank by the punch, so that the titanium alloy blank gradually plastically deforms, and then the titanium alloy blank can flow and deform according to the shape of the punch, so as to change the shape and size of the titanium alloy blank, so as to achieve the design requirement in the subsequent form.

[0051] The electronic device controls the punch to press down according to the positioning result is described in detail as follows: In some embodiments, the electronic device controls the punch to press down according to the positioning result can include: the electronic device judges whether the verticality deviation indicated by the positioning result meets the preset tolerance requirement; if it meets, the electronic device controls the punch to press down; if it does not meet, the electronic device controls the punch to move and re-executes the alignment positioning step according to the verticality deviation until the verticality deviation indicated by the latest positioning result meets the preset tolerance requirement, and then controls the punch to press down.

[0052] During the process of controlling the punch to press down, the electronic device can first judge whether the verticality deviation indicated by the positioning result meets the preset tolerance requirement, so as to judge whether the alignment positioning between the punch and the titanium alloy blank is accurate. If it meets, it means that the alignment positioning between the punch and the titanium alloy blank is accurate, at this time, the electronic device controls the punch to press down, based on which the pressure applied by the punch to the titanium alloy blank is uniform; if it does not meet, it means that the alignment positioning between the punch and the titanium alloy blank is not accurate, if the punch is controlled to press down at this time, the pressure applied by the punch to the titanium alloy blank will be non-uniform. In order to ensure that the target special-shaped ring forge piece can meet the design requirement in the subsequent form, the electronic device controls the punch to move and re-executes the alignment positioning step according to the verticality deviation until the verticality deviation indicated by the latest positioning result meets the preset tolerance requirement, so that the alignment positioning between the punch and the titanium alloy blank is accurate, at this time, the electronic device controls the punch to press down, so as to effectively avoid defects such as deformation and cracks of the titanium alloy blank.

[0053] In some embodiments, the preset tolerance requirement is that the angle difference between the angle between the connecting line and the upper end face of the forming die of the tire mold and the vertical line of the upper end face is less than or equal to the preset deviation threshold.

[0054] The preset deviation threshold value is any value in the range of [0°, 1°].

[0055] For example, the preset deviation threshold value is 1°, or 0.5°.

[0056] It should be noted that, in the case that the perpendicularity deviation indicated by the positioning result meets the preset tolerance requirement, the punch and the titanium alloy blank can be ensured to be centered, which is the key to realizing subsequent accurate embedding and avoiding damage to the die or affecting the quality of the forged piece (such as uneven wall thickness), so as to improve the quality of the subsequent target special-shaped ring forged piece and reduce the material utilization rate (such as reducing waste products / repair).

[0057] The electronic device real-time detects the embedding depth of the punch relative to the titanium alloy blank as follows: In some embodiments, the electronic device real-time detects the embedding depth of the punch relative to the titanium alloy blank, which can include: the electronic device determines that the fixed height between the upper end face of the die former forming die and the lower end face of the die former forming die is the die closing height H1; the electronic device real-time measures the current height H2 between the lower end face of the punch and the lower end face of the die former forming die; and the electronic device obtains the embedding depth ΔH according to the height calculation formula ΔH=H1-H2.

[0058] In the process of determining the embedding depth ΔH, the electronic device can first determine that the fixed height between the upper end face of the die former forming die and the lower end face of the die former forming die is the die closing height H1, which is also the forging height of the subsequent target special-shaped ring forged piece. Then, the electronic device real-time measures the current height H2 between the lower end face of the punch and the lower end face of the die former forming die. Since the electronic device controls the continuous downward pressing of the punch, the current height H2 is real-time changing, and gradually shortens as the punch continues to press down. Further, the electronic device calculates the die closing height H1 and the current height H2, and obtains the embedding depth ΔH by using the height calculation formula ΔH=H1-H2.

[0059] It can be understood that, if ΔH=H1-H2 is negative, it means that the lower end face of the punch is located above the die former forming die, at this time, the punch does not contact the titanium alloy blank in the die former forming die, and cannot apply pressure to the titanium alloy blank. If ΔH=H1-H2 is 0, it means that the lower end face of the punch just contacts the upper end face of the die former forming die, at this time, the punch contacts the titanium alloy blank in the die former forming die, but does not apply pressure to the titanium alloy blank. If ΔH = H1 - H2 is positive, it means that the lower end surface of the punch is below the upper end surface of the tire mold forming die, at this time, the punch has contact with the titanium alloy blank in the tire mold forming die, and the titanium alloy blank has been subjected to pressure.

[0060] Step 104: When it is detected that the embedding depth reaches the preset depth threshold, control the second upper anvil to be pressed down to the upper end surface of the tire mold forming die, so that the titanium alloy blank is finally formed in the closed die cavity formed by the combination of the lower anvil, the tire mold forming die and the second upper anvil, and a target special-shaped ring forge piece is obtained.

[0061] The preset depth threshold is a key depth value that is set in advance, which can be determined according to the key parameters such as the size, shape and tolerance range specified in the design drawing of the target special-shaped ring forge piece, and / or the plastic deformation ability and work hardening characteristics of the titanium alloy material, or can be determined by the staff according to actual experience, so as to ensure that the finally formed target special-shaped ring forge piece can meet the use performance and assembly requirements of the product.

[0062] It should be noted that a reasonable preset depth threshold can effectively prevent the punch from being pressed down too much, and prevent problems such as equipment overload and die damage caused by excessive deformation of the titanium alloy blank.

[0063] In combination with Figure 2b , an example is shown in Figure 2c , which is a scene schematic diagram for determining a target special-shaped ring forge piece provided by the embodiments of the present application. As can be seen from Figure 2c , in the process of determining the target special-shaped ring forge piece, the electronic device can first compare the real-time detected embedding depth with the preset depth threshold, until the latest embedding depth reaches the preset depth threshold, which means that the titanium alloy blank has completed the preliminary plastic deformation and reached the predetermined processing stage. Based on this, the electronic device controls the second upper anvil to be pressed down as a whole until the upper end surface of the tire mold forming die, at this time, the above-mentioned punch has been completely embedded in the inside of the titanium alloy blank, and the whole control operation can make the alloy blank be finally formed in the closed die cavity formed by the combination of the lower anvil, the tire mold forming die and the second upper anvil, and a target special-shaped ring forge piece is obtained.

[0064] It should be noted that in order to ensure the accurate forming of the target special-shaped ring forge piece, the titanium alloy blank is heated and kept at a temperature range of (Tβ-50) ℃ to (Tβ-30) ℃ during the step-by-step processing of the titanium alloy blank in steps 102-104.

[0065] For example, assuming that the target special-shaped ring forge piece is an S-bent special-shaped ring forge piece, as shown in Figure 3a , which is one of the simulation diagrams of the S-bent special-shaped ring forge piece provided by the embodiments of the present application; as shown in Figure 3bThe image shown is the second simulation diagram of the S-bend irregular ring forging provided in the embodiments of this application. From... Figure 3a It can be seen that: the electronic equipment controls the downward pressure of the punch and detects the embedding depth of the punch relative to the titanium alloy billet in real time; this embedding depth has reached the preset depth threshold; from Figure 3b It can be seen from this that: Figure 3a Based on this, the electronic device controls the second upper hammer anvil to press down as a whole onto the upper end face of the die forming mold, so that the punch is completely embedded in the interior of the titanium alloy billet, and the titanium alloy billet is finally formed in the closed mold cavity formed by the combination of the lower hammer anvil, the die forming mold, and the second upper hammer anvil, to obtain the S-shaped ring forging.

[0066] For example, combined Figure 3a and Figure 3b ,like Figure 4 The image shown is a physical drawing of the S-shaped ring forging provided in an embodiment of this application. Figure 4 The S-shaped ring forging shown is determined based on the technical solution shown in steps 101-104 above, and the dimensions, performance and quality of the S-shaped ring forging meet the design requirements.

[0067] It should be noted that the S-shaped ring forging exhibits a strength of approximately 700 MPa and a plasticity of approximately 28% at 650℃; and a strength of approximately 610 MPa and a plasticity of approximately 40% at 700℃. The creep rupture time is 58 hours at 650℃ and a stress of 280 MPa; and 25 hours at 700℃ and a stress of 200 MPa. The high-magnification microstructure of this S-shaped ring forging primarily consists of equiaxed and / or elongated primary α phases distributed within 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 S-shaped ring forging meet the forging acceptance requirements.

[0068] The following section details how, when the embedded depth reaches a preset depth threshold, the electronic device controls the second upper hammer anvil to press down entirely onto the upper surface of the mold forming die: In some embodiments, when the embedding depth is detected to reach a preset depth threshold, the electronic device controls the second upper hammer anvil to press down onto the upper surface of the mold forming die, which may include at least one of the following implementation methods: Implementation method 1: The electronic device detects the contact pressure of the punch in real time; when the contact pressure of the punch reaches the preset pressure threshold and the embedding depth reaches the preset depth threshold, the electronic device automatically triggers the control of the second upper hammer anvil to press down to the upper surface of the mold forming die.

[0069] The punch contact pressure refers to the interaction force generated when the punch contacts the titanium alloy blank during the pressing process. It should be noted that, during the processing of the titanium alloy blank, a suitable punch contact pressure can ensure that the punch effectively performs the forming operation on the titanium alloy blank. If the punch contact pressure is too small, the titanium alloy blank may not achieve the desired deformation effect; if the punch contact pressure is too large, the titanium alloy blank and / or the punch may be damaged.

[0070] It can be understood that, if the punch contact pressure is 0, it means that either of the following situations occurs. Situation one: the lower end surface of the punch is located above the upper end surface of the tire mold forming die, at this time, the punch does not contact the titanium alloy blank in the tire mold forming die and cannot apply pressure to the titanium alloy blank; situation two: the lower end surface of the punch just contacts the upper end surface of the tire mold forming die, at this time, the punch contacts the titanium alloy blank in the tire mold forming die, but does not apply pressure to the titanium alloy blank. If the punch contact pressure is greater than 0, it means that the lower end surface of the punch is located below the upper end surface of the tire mold forming die, at this time, the punch contacts the titanium alloy blank in the tire mold forming die and has applied pressure to the titanium alloy blank.

[0071] In the process of determining the target special-shaped ring forge piece, the electronic device detects the punch contact pressure in real time while detecting the embedding depth of the punch relative to the titanium alloy blank in real time, then determines whether the punch contact pressure reaches a preset pressure threshold and whether the embedding depth reaches a preset depth threshold, if the current punch contact pressure reaches the preset pressure threshold and the embedding depth reaches the preset depth threshold, the second upper anvil is automatically triggered to be controlled to be pressed down to the upper end surface of the tire mold forming die, if the current punch contact pressure does not reach the preset pressure threshold and / or the embedding depth does not reach the preset depth threshold, the punch is continuously controlled to be pressed down until the latest punch contact pressure reaches the preset pressure threshold and the embedding depth reaches the preset depth threshold, at this time, the second upper anvil is automatically triggered to be controlled to be pressed down to the upper end surface of the tire mold forming die, so that the alloy blank is finally formed in the closed die cavity formed after the lower anvil, the tire mold forming die and the second upper anvil are combined, and the target special-shaped ring forge piece is obtained.

[0072] Implementation 2: The electronic device controls the second upper anvil to be pressed down to the upper end surface of the tire mold forming die, so that the titanium alloy blank is finally formed in the closed die cavity formed after the lower anvil, the tire mold forming die and the second upper anvil are combined, and an initial target special-shaped ring forge piece is obtained; the electronic device performs repair, heat treatment, physical and chemical testing, rough machining and ultrasonic flaw detection operations on the initial target special-shaped ring forge piece, and obtains the target special-shaped ring forge piece.

[0073] Among them, the repair refers to the process of repairing defects or adjusting the size of the initial target special ring forge piece. In the forging process, defects such as cracks, folds, and size inconsistencies may occur. The purpose of repair is to eliminate these defects through welding, grinding, and correction, so that the target special ring forge piece meets the specified quality requirements.

[0074] Heat treatment refers to changing the internal structure of the initial target special ring forge piece through heating, holding and cooling processes, so as to improve the mechanical properties and processing performance of the initial target special ring forge piece. Optionally, heat treatment can include annealing, normalizing, quenching and tempering, etc. For the initial target special ring forge piece, heat treatment can eliminate internal stress and improve the strength, hardness and toughness of the titanium alloy material.

[0075] Physical and chemical testing refers to the process of testing the physical and chemical properties of the initial target special ring forge piece. The physical and chemical testing can include tensile test, impact test, hardness test, metallographic analysis, etc. to evaluate the mechanical properties such as strength, plasticity, toughness and hardness of the initial target special ring forge piece, and whether the chemical composition and microstructure of the titanium alloy material meet the requirements.

[0076] Rough machining refers to the process of initially machining the initial target special ring forge piece to make it close to the final shape and size. Optionally, rough machining can include turning, milling, drilling and other operations, the purpose of which is to remove excess material on the surface of the initial target special ring forge piece.

[0077] Ultrasonic flaw detection is a non-destructive testing method that uses the propagation characteristics of ultrasonic waves in titanium alloy materials to detect internal defects of the initial target special ring forge piece. By emitting ultrasonic waves and receiving the reflected signals, it can be determined whether there are cracks, pores, inclusions and other defects inside the initial target special ring forge piece, and the location and size of the defects can be determined.

[0078] After the electronic device determines the initial target special ring forge piece, since the initial target special ring forge piece may still have some small defects, the repair, heat treatment, physical and chemical testing, rough machining and ultrasonic flaw detection operations performed on the initial target special ring forge piece are important steps to ensure the quality, performance and safety of the forge piece. These operations are interrelated and together constitute a complete processing flow of the special ring forge piece from the initial state to the final product.

[0079] In the embodiment of the present application, through the step-by-step forming operation of the die mold, the first upper anvil, the second upper anvil, the punch on the second upper anvil, the die mold and the lower anvil are combined to process and form the titanium alloy bar according to steps 101-104, so as to obtain the target special-shaped ring forge piece. The whole process does not need to rely on special-shaped rolling mill and special-shaped rolling die, and can effectively improve the processing efficiency and forming effect of the target special-shaped ring forge piece and reduce the mold cost of the intelligent preparation process.

[0080] In addition, the technical solutions shown in steps 101-104 can ensure that each titanium alloy bar undergoes the same forming process during processing, so as to ensure that each target special-shaped ring forge piece formed finally has consistent quality and performance. Whether in large-scale production or small-batch customized production, the processing and forming can be strictly carried out according to the preset standard (i.e. the above technical solution), the quality fluctuation of the titanium alloy product is reduced, and the qualified rate of the titanium alloy product is improved.

[0081] In order to better understand the embodiments of the present application, the forge macrostructure and the forge microstructure of the target special-shaped ring forge piece (such as the S-bent special-shaped ring forge piece) are described in detail as follows: Exemplarily, as shown in Figure 5a , it is a photo schematic diagram of the forge macrostructure of the S-bent special-shaped ring forge piece provided by the embodiment of the present application. It can be seen from Figure 5a that: there are no visually visible cracks, shrinkage holes, pores, folds, inclusions, segregation and other defects affecting use on the etched surface of the macrotest piece. There are no segregation type bright strips, bright blocks, β spots, hard α phase and soft α phase inclusions and high-density inclusions. The macrostructure of the macrotest piece should be fine and blurred grains, and there should be no obvious and visually visible clear grains. The macrostructure should meet the requirements of 1st to 3rd levels in GJB2220A-2018 Figure 1 .

[0082] Exemplarily, as shown in Figure 5b , it is a photo schematic diagram of the forge macrostructure of the S-bent special-shaped ring forge piece provided by the embodiment of the present application. It can be seen from Figure 5b that: the microstructure is all α+β region processing structure, which meets the 4th level in GJB2220A-2018 Figure 3, and the volume fraction of primary α phase is 20%, and the morphology of the structure meets the standard requirements.

[0083] In summary, combined with Figure 5a and Figure 5b , it can be known that the size, performance and quality of the S-bent special-shaped ring forge piece meet the design requirements.

[0084] The forge room temperature tensile properties, forge high temperature tensile properties and forge high temperature endurance properties of the S-bent special-shaped ring forge piece are described in detail as follows: Exemplarily, Table 1 is a table of the room temperature tensile properties of the S-bend special-shaped ring forging.

[0085] Table 1: Rm represents the tensile strength, which represents the maximum stress that the titanium alloy material can withstand in the tensile test, with the unit of megapascal (MPa); Rp0.2 represents the 0.2% yield strength, which represents the stress that the titanium alloy material can withstand when producing 0.2% plastic deformation, with the unit of megapascal; A represents the elongation after fracture, which represents the ratio of the total deformation of the gauge section to the original gauge after the titanium alloy material is fractured in tension, expressed in percentage; Z represents the reduction of area, which represents the ratio of the area of the reduced section to the original cross-sectional area after the titanium alloy material is fractured in tension, expressed in percentage; HBW represents the Brinell hardness, which represents the hardness value of the titanium alloy material.

[0086] It should be noted that Table 1 shows the results of two tensile property tests of the titanium alloy material at room temperature and the corresponding acceptance standards.

[0087] As can be seen from Table 1, the results of the two tensile property tests of the titanium alloy material at room temperature both meet or exceed the given acceptance standards, indicating that the titanium alloy material exhibits good performance in terms of tensile strength, yield strength, elongation after fracture, reduction of area, and hardness, meeting the use requirements.

[0088] Exemplarily, Table 2 is a table of the high-temperature tensile properties of the S-bend special-shaped ring forging.

[0089] Table 2: It should be noted that Table 2 shows the results of the tensile property tests of the titanium alloy material at 650°C and 700°C, as well as the corresponding acceptance standards.

[0090] As can be seen from Table 2, the results of the tensile property tests of the titanium alloy material at 650°C and 700°C both meet or exceed the given acceptance standards. In terms of tensile strength, 0.2% yield strength, elongation after fracture, and reduction of area, the titanium alloy material exhibits good performance. In particular, at high temperature (700°C), the titanium alloy material can still maintain high strength and plasticity, indicating that the titanium alloy material has excellent high-temperature performance. Therefore, the titanium alloy material is suitable for application scenarios that require high temperature and high stress.

[0091] Exemplarily, Table 3 is a table of the high-temperature endurance properties of the S-bend special-shaped ring forging.

[0092] Table 3: It should be noted that Table 3 shows the performance data of the titanium alloy material after long-time testing at a specified stress level at a test temperature of 650 DEG C and 700 DEG C, specifically the cross-sectional shrinkage (Z / %) and the corresponding test time, and the corresponding acceptance standard is also given.

[0093] As can be seen from Table 3, the titanium alloy material is subjected to long-time testing at a specified stress level at a test temperature of 650 DEG C and 700 DEG C, and the cross-sectional shrinkage of the titanium alloy material far exceeds the corresponding acceptance standard. It shows that the titanium alloy material can still maintain good plasticity and toughness under these high temperature and high stress conditions. Therefore, the titanium alloy material is suitable for application scenarios that can withstand a specified stress level at a temperature of 650 DEG C and 700 DEG C.

[0094] In summary, the intelligent preparation method of the titanium alloy profiled ring forging provided by the embodiments of the present application can solve the complex problems that occur in the production process of the S-bent profiled ring forging of Ti65 alloy, and can quickly and efficiently produce the S-bent profiled ring forging of Ti65 alloy, and can greatly improve the strength and plasticity of the S-bent profiled ring forging of Ti65 alloy, without relying on profiled rolling mills and profiled rolling dies, and can effectively improve the processing efficiency and forming effect of the target profiled ring forging and reduce the mold cost of the intelligent preparation process.
