Description

Technical Field

[0001] The present invention relates to the technical field of forging, and particularly relates to a manufacturing device and a forging method for high-quality titanium rod forgings. Background Art

[0002] For example, the publication number is CN119237638A, and the name is a forging device for the production of titanium alloy rods, belonging to the technical field of forging equipment. It includes a moving component, and the moving component includes a track. A moving block is slidably connected to the upper side wall of the track. A clamping component is arranged on one side of the moving block. The clamping component includes a fixed ring shell. A guiding ring body is rotatably connected inside the fixed ring shell. A rotating ring block is rotatably connected inside the guiding ring body. A plurality of extrusion components are inserted on the rotating ring block; the extrusion component includes a guiding pressing block inserted on the rotating ring block. An extrusion block is arranged on the lower side of the guiding pressing block. A fixed pipe is fixedly connected to the upper end of the extrusion block. Through the setting of the moving component and the clamping component, this device can effectively clamp, rotate, and convey titanium alloy ingot rods with different diameters. At the same time, in cooperation with the extrusion component and the contact component, multiple cross plates can all contact the surface of the titanium alloy ingot rod, expanding the contact surface with the surface of the titanium alloy ingot rod and improving the clamping effect.

[0003] The above-mentioned titanium rod manufacturing equipment mainly solves the clamping problem of titanium rods. However, during the rolling process, due to coarse grains and local stress concentration, it is impossible to make full use of the characteristics of the improved plasticity and reduced deformation resistance of titanium materials at high temperatures to hammer the titanium rod in all directions to promote the occurrence of dynamic recrystallization to form fine equiaxed grains and avoid the potential cracking risk caused by local stress concentration. Moreover, titanium is extremely easy to react with oxygen and nitrogen to form an oxide layer or a nitride layer at high temperatures, resulting in an oxide layer, impurities, and uneven areas remaining on the surface of the titanium rod during the forging process. Therefore, the present application provides a manufacturing device and a forging method for high-quality titanium rod forgings to meet the requirements. Summary of the Invention

[0010] Among them, one end of the rotating rod is provided with an extrusion block, and one end of the extrusion block is provided with a push spring. The extrusion block is located inside the second installation groove.

[0011] Among them, the gas protection component includes a ring shell and a ring tube. The ring shell is installed between the second inner tube and the first inner tube. A plurality of communicating tubes communicating with the inside of the ring shell are arranged on the inner wall of the ring tube. A ventilation tube penetrating the outer shell is arranged on the upper part of the outer surface of the ring tube.

[0012] Among them, the heating component includes a conical shell. The conical shell is installed at one end of the outer shell and the second inner tube. A heating ring is arranged inside the conical shell. A plurality of through holes are formed on the outer surface of the conical shell.

[0015] The present invention also provides a forging method for a high-quality titanium rod, and the specific forging method is as follows:

[0016] S1. After the titanium rod is taken out of the heating furnace, it is grabbed by the forging claw and sent into the inside of the hammer pressing assembly. The hammer pressing assembly hammers the titanium rod in all directions, thereby pre-forging the titanium rod to refine the grain structure inside the titanium rod and improve the microstructure of the material;

[0017] S2. After being forged by the hammer pressing assembly, the titanium rod is sent into the interior of the extrusion mechanism, and the gas protection assembly sprays inert gas to fill the internal cavities of the extrusion mechanism, the heating assembly and the hammer pressing assembly, so that the titanium rod is forged under the protection of the inert gas, and the extrusion assembly contacts and squeezes the surface of the titanium rod to clean the impurities on the surface of the titanium rod;

[0018] S3. The titanium rod processed by the extrusion mechanism will be sent into the interior of the heating component. The heating component heats the titanium rod to release the stress generated by the forging of the titanium rod. Finally, the titanium rod is rolled by the rolling component.

[0019] In summary, the technical effects and advantages of the present invention are as follows:

[0020] 1. In the present invention, the titanium rod is heated to the β phase region (900-1000°C) or the α+β two-phase region (750-950°C) in a heating furnace, at which time the plasticity of titanium is significantly improved and the deformation resistance is reduced. Then, the hammer pressing assembly applies all-round hammering to the titanium rod, which promotes dynamic recrystallization through plastic deformation at high temperature. Dynamic recrystallization will form fine equiaxed grains to replace the original coarse deformed grains, refine the grain structure and improve the mechanical properties. The all-round hammering of the hammer pressing assembly makes the titanium rod evenly stressed in multiple directions to avoid local stress concentration.

[0021] 2. In the present invention, titanium reacts extremely easily with oxygen and nitrogen at high temperatures to form an oxide layer or a nitride layer. The filling of an inert gas (such as argon) isolates the air, preventing the titanium rod surface from undergoing chemical reactions due to high-temperature exposure during subsequent processing, and maintaining the surface purity. The inert gas not only protects the titanium rod but also maintains the internal environment of the hammering assembly, the heating assembly, and the extrusion mechanism. There may be an oxide layer, impurities, or uneven areas remaining on the surface of the titanium rod after hammering. The extrusion assembly can effectively scrape off these surface defects by directly contacting and applying pressure. The extrusion pressure can eliminate the surface stress concentration that may occur during the hammering process, reducing the risk of cracking during subsequent processing or use.

[0022] 3. During the hammering and extrusion processes in the present invention, a large amount of residual stress generated by work hardening accumulates inside the titanium rod. The heating assembly heats the titanium rod to an appropriate temperature of 500 - 700 °C, causing dynamic recovery and recrystallization of the material, thereby eliminating or significantly reducing the residual stress, preventing cracking caused by stress concentration during subsequent processing or use, and reducing the deformation resistance of the titanium rod by heating to provide a more deformable material state for subsequent rolling.

Specific implementation mode

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Example 1. Refer to Figures 1 to 20 A high-quality titanium rod forging manufacturing device as shown, including a support frame 1, a rolling frame 2 is arranged on one side of the support frame 1, an installation cover plate 9 is arranged on the inner wall of the support frame 1, a hammer pressing assembly 5 for continuously hammering the surface of the titanium rod in all directions is arranged inside the installation cover plate 9, an extrusion mechanism 7 for improving the surface quality of the titanium rod is arranged on one side of the hammer pressing assembly 5, a heating assembly 6 for releasing the hot rolling stress of the titanium rod is arranged on one side of the extrusion mechanism 7, and a rolling assembly 4 for adjusting the hot rolling strength of the titanium rod is arranged inside the support frame 1;

[0047] The extrusion mechanism 7 includes a gas protection assembly 72 for releasing inert gas to improve the surface quality of the titanium rod and an extrusion assembly 71 for extruding the surface of the titanium rod to remove the oxide layer or impurities.

[0048] It should be noted that after the titanium rod is taken out of the heating furnace, it is grabbed by the forging claw and sent into the inside of the hammer pressing assembly 5. The hammer pressing assembly 5 hammers the titanium rod in all directions, thereby pre-forging the titanium rod to refine the crystal grain structure inside the titanium rod and improve the microstructure of the material;

[0049] Among them, the titanium rod is heated in a heating furnace to 900-1000°C in the β phase region or 750-950°C in the α+β two-phase region. At this time, the plasticity of titanium is significantly improved and the deformation resistance is reduced. Then the hammer pressing component 5 applies all-round hammering to the titanium rod, which promotes dynamic recrystallization through plastic deformation at high temperature. Dynamic recrystallization will form fine equiaxed grains to replace the original coarse deformed grains, refine the grain structure and improve the mechanical properties. The all-round hammering of the hammer pressing component makes the titanium rod evenly stressed in multiple directions to avoid local stress concentration.

[0050] After being forged by the hammer pressing assembly 5, the titanium rod is sent into the interior of the extrusion mechanism 7, and the gas protection assembly 72 sprays inert gas to fill the internal cavities of the extrusion mechanism 7, the heating assembly 6 and the hammer pressing assembly 5, so that the titanium rod is forged under the protection of the inert gas, and the extrusion assembly 71 contacts and squeezes the surface of the titanium rod to clean the impurities on the surface of the titanium rod;

[0051] Among them, titanium is very easy to react with oxygen and nitrogen at high temperature to form an oxide layer or a nitride layer. The filling of inert gas such as argon isolates the air, prevents the surface of the titanium rod from chemically reacting due to high temperature exposure during subsequent processing, and keeps the surface pure. The inert gas not only protects the titanium rod, but also maintains the internal environment of the hammering component 5, the heating component 6 and the extrusion mechanism 7. The surface of the titanium rod after hammering may have residual oxide layers, impurities or uneven areas. The extrusion component 71 can effectively scrape off these surface defects by direct contact and applying pressure. The extrusion pressure can eliminate the surface stress concentration that may be generated during the hammering process, and reduce the risk of cracking during subsequent processing or use.

[0052] The titanium rod processed by the extrusion mechanism 7 will be sent into the interior of the heating component 6, and the heating component 6 will heat the titanium rod to release the stress generated by the forging of the titanium rod. Finally, the titanium rod will be rolled by the rolling component 4.

[0053] During the hammering and extrusion process, a large amount of residual stress caused by work hardening will accumulate inside the titanium rod. The heating component 6 heats the titanium rod to an appropriate temperature such as 500-700°C to cause dynamic recovery and recrystallization of the material, thereby eliminating or significantly reducing the residual stress and preventing cracking due to stress concentration during subsequent processing or use. The deformation resistance of the titanium rod is reduced by heating, providing a material state that is easier to deform for subsequent rolling.

[0054] Embodiment 2: Based on the hammer pressing assembly 5 provided in embodiment 1, this embodiment provides a further technical solution of the hammer pressing assembly 5.

[0055] refer to Figures 7 to 12The shown hammering component 5 includes a sleeve 54 and a first inner tube 57. The first inner tube 57 is installed on the inner wall of the mounting cover plate 9. A plurality of first mounting grooves 513 distributed in an annular array are formed on the outer surface of the first inner tube 57. A support rod 512 is slidably installed inside the first mounting groove 513. One end of the support rod 512 is provided with a push block 58, and the other end of the support rod 512 is provided with a hammering block 511. A spring 59 is sleeved on the outer surface of the support rod 512, and the spring 59 is located at the bottom of the push block 58. The hammering block 511 is located inside the first inner tube 57.

[0056] The hammering component 5 further includes a driving motor 51 installed on one side of the support frame 1. The output end of the driving motor 51 is provided with a gear 52. A toothed ring 53 is arranged on the outer surface of the sleeve 54. The toothed ring 53 meshes with the gear 52. A plurality of top blocks 56 distributed in an annular array are arranged on the inner wall of the sleeve 54. Both the top block 56 and the push block 58 are semi-cylindrical. Two bearings 55 are symmetrically arranged on the inner wall of the sleeve 54, and both the two bearings 55 are installed on the outer surface of the first inner tube 57.

[0057] It should be noted that when the titanium rod is fed into the first inner tube 57 during use, the driving motor 51 drives the gear 52 to rotate through the output end. The gear 52 meshes with the toothed ring 53 to drive the sleeve 54 to rotate. The sleeve 54 rotates on the outer surface of the first inner tube 57 through the bearings 55. The top block 56 is driven to rotate by the sleeve 54. Since both the top block 56 and the push block 58 are semi-cylindrical, the push block 58 is squeezed by the rotation of the top block 56, so that the push block 58 drives the support rod 512 to slide inside the first mounting groove 513. Because the set push block 58 and the top block 56 are arranged in a staggered manner, the top block 56 can squeeze the push block 58 to move when it moves. The spring 59 provides a supporting force for the reset of the push block 58. When the support rod 512 moves towards the central axis of the first inner tube 57, the support rod 512 will also drive the hammering block 511 to move towards the central axis. The set multiple hammering blocks 511 are arranged in an annular array and can synchronously squeeze the titanium rod located in the middle of the first inner tube 57. When the sleeve 54 rotates, the top block 56 and the push block 58 are quickly misaligned, so that the first inner tube 57 quickly hits the surface of the titanium rod.

[0058] Among them, the multiple hammering blocks are distributed in an annular array, and the titanium rod can be squeezed 360° in all directions to ensure that the deformation force is evenly applied to the circumference of the titanium rod. The uniform stress distribution promotes dynamic recrystallization, avoids cracking caused by local overload, and improves the dimensional stability and fatigue life of the material. The top block 56 and the push block 58 are arranged in a staggered manner. When the sleeve 54 rotates, the top block 56 periodically squeezes the push block 58, and a high-frequency reciprocating motion is realized through the reset of the spring 59. The high-frequency light hitting is used to replace the heavy hitting to increase the hammering frequency, reduce the single impact energy, and reduce the deformation resistance. The deformation heat effect generated by the high-frequency light hitting is lower than that of traditional hammer forging, avoiding excessive decomposition of the β phase or grain coarsening.

[0059] Embodiment 3. Based on the extrusion mechanism 7 and the heating component 6 provided in Embodiment 1, this embodiment provides a further technical solution for the extrusion component 71, the gas protection component 72, and the heating component 6.

[0060] The gas protection component 72 includes an annular shell 724 and an annular tube 722. The annular shell 724 is installed between the second inner tube 712 and the first inner tube 57. A plurality of communicating tubes 723 communicating with the inside of the annular shell 724 are provided on the inner wall of the annular tube 722. An air vent tube 721 penetrating through the outer shell 711 is provided on the upper part of the outer surface of the annular tube 722.

[0061] It should be noted that after the titanium rod is hammered by the hammering component 5, the inert gas enters the inside of the annular tube 722 through the gas protection component 72, then enters the inside of the annular shell 724 through the communicating tubes 723, and diffuses through the annular shell 724 to contact the surface of the titanium rod through the inert gas inside the second inner tube 712 and the first inner tube 57 to prevent the surface of the titanium rod from oxidizing.

[0062] The extrusion component 71 includes an outer shell 711 and a second inner tube 712. A plurality of second installation grooves 713 are provided on the outer surface of the second inner tube 712. A plurality of limiting blocks 710 are provided on the inner wall of the outer shell 711, and an annular ring 714 is provided inside the limiting block 710. A plurality of rotating rods 715 distributed in an annular array are rotatably installed on the outer surface of the annular ring 714, and the limiting block 710 is used to limit the sliding of the rotating rod 715 on the surface of the annular ring 714.

[0063] One end of the rotating rod 715 is provided with an extrusion block 717, one end of the extrusion block 717 is provided with a push spring 716, and the extrusion block 717 is located inside the second installation groove 713.

[0064] Among them, after the titanium rod is hammered by the hammering component 5, the titanium rod will be sent between a plurality of extrusion blocks 717, and the provided push spring 716 provides a thrust for the extrusion block 717, so that the extrusion block 717 can contact and extrude the surface of the titanium rod, and the extrusion block 717 will also drive the rotating rod 715 to rotate on the outer surface of the annular ring 714.

[0065] The heating component 6 includes a conical shell 61. The conical shell 61 is installed at one end of the outer shell 711 and the second inner tube 712. A heating ring 62 is provided inside the conical shell 61, and a plurality of through holes 63 are provided on the outer surface of the conical shell 61.

[0066] Among them, when the titanium rod is extruded by the extrusion block 717, it will be sent into the conical shell 61, and the heating ring 62 reheats the titanium rod to release the stress generated by rolling.

[0067] Among them, before the hammering component 5 hammers the titanium rod, an inert gas such as argon enters the annular tube 722 through the gas protection component 72 and further diffuses into the second inner tube 712 and the first inner tube 57, ensuring that the surface of the titanium rod does not contact with oxygen in the air during high temperature or deformation, and avoiding the formation of a surface oxide layer.

[0068] After being hammered, the titanium rod is sent between several extrusion blocks 717. The extrusion blocks 717 are provided with a thrust by the push spring 716 and can closely contact and extrude the surface of the titanium rod. After being extruded, the titanium rod enters the inside of the conical shell 61, and the heating ring 62 reheats it. The purpose is to allow the titanium rod to release the stress accumulated due to the previous processing of hammering and extrusion, and it can also cause dynamic recovery or recrystallization phenomena inside the titanium rod, thereby effectively eliminating or alleviating the residual stress and reducing the risk of cracking caused by stress concentration during subsequent use.

[0069] Embodiment 4. For the rolling component 4 proposed in Embodiment 1, this embodiment provides a further technical solution for the rolling component 4.

[0070] The rolling component 4 includes two movable shaft blocks 47 and a shaft frame 43. The two movable shaft blocks 47 are installed inside the rolling frame 2. The two shaft frames 43 are both slidably installed inside the rolling frame 2. Rolling wheels 46 are rotatably installed between the two shaft frames 43 and the movable shaft blocks 47. One end of the rolling wheel 46 swings up and down inside the movable shaft block 47 through a rotating shaft, and the swing amplitude is less than thirty degrees, ensuring that the movable shaft block 47 will not move when the rolling wheel 46 moves.

[0071] On one side of the upper part of the rolling frame 2, two chain gears 45 are provided, and drive chains 44 are wound around the outer surfaces of the two chain gears 45. One end of each of the two drive chains 44 is fixedly connected to one of the shaft frames 43 located above. The other ends of the two drive chains 44 are both equipped with hydraulic rods 41, and the two hydraulic rods 41 are fixedly installed on both sides of one of the shaft frames 43 located at the bottom. One end of each of the two rolling wheels 46 is provided with a connecting shaft 42, and a transmission shaft 3 is provided inside each of the two connecting shafts 42.

[0072] It should be noted that the distance between the two shaft frames 43 is changed by stretching the drive chain 44 through the extension of the hydraulic rod 41 according to the size of the rolled titanium rod. When the total length becomes shorter after the hydraulic rod 41 contracts, the drive chain 44 will pull one of the upper shaft frames 43 to move, increasing the distance between the two shaft frames 43, thereby adjusting the distance between the two rolling wheels 46 to adjust the rolling size of the titanium rod. A counterweight is provided on the shaft frame 43 at the bottom of the inner cavity of the rolling frame 2 to ensure sufficient gravity support when the upper shaft frame 43 slides. The provided transmission shaft 3 drives the rolling wheel 46 to rotate through the connecting shaft 42 to roll the titanium rod.

[0073] Among them, through the telescopic movement of the hydraulic rod 41, the distance between the two shaft frames 43 can be accurately adjusted, and further the distance between the two rolling wheels 46 can be adjusted, allowing for the adaptive processing of titanium rods with different diameters or cross-sectional shapes, and being able to meet the production requirements of titanium rods of different specifications. The transmission shaft 3 drives the rolling wheel 46 to rotate through the connecting shaft 42, ensuring the stability and efficiency of power transmission.

[0074] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
