[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figures 1-7 This utility model discloses an isothermal forging auxiliary device for producing U-shaped forgings from titanium alloy, including a frame 1 and a control console 2 located on one side of the frame 1, and also including an upper die assembly 3, a lower die assembly 4, a limiting assembly 5, a buffer assembly 6, and a temperature control assembly 7, wherein:

[0026] The frame 1 is equipped with a hydraulic platform 11. The frame 1 is fixed to the bottom surface by expansion bolts. A pressure-bearing platform 12 is provided below the hydraulic platform 11.

[0027] Please refer to the appendix. Figure 6 The limiting component 5 includes a limiting baffle 51, and a locking block 52 is provided on the opposite side of the limiting baffle 51. One end of the locking block 52 abuts against the blank 8, and the other end is fitted with a spiral column 53. The spiral column 53 is mounted on a servo motor 54, and the servo motor 54 is electrically connected to the control console 2.

[0028] Please refer to the appendix. Figure 5The buffer assembly 6 includes a buffer plate 61, with several buffer springs 62 welded to the bottom of the buffer plate 61. Buffer grooves 121 are welded to the other end of the buffer springs 62. The buffer plate 61 fits into the buffer grooves 121 and slides in fit. The top surface of the buffer plate 61 is fixed to the bottom surface of the lower mold base 42 by screws. Specifically, when the lower mold 41 is subjected to an impact force, the lower mold base 42 drives the buffer plate 61 to move down and compress the buffer springs 62 to buffer the impact force.

[0029] The limiting baffle 51 is welded to the bottom surface of the sealing groove 411 of the lower mold 41, and the bottom of the locking block 52 abuts against the sealing groove 411 and slides in fit.

[0030] In this embodiment, the servo motor 54 drives the spiral column 53 to rotate. The spiral column 53 interacts with the locking block 52. Through the spiral force, the locking block 52 slides on the surface of the sealing groove 412 and pushes the billet 8 until the other end of the billet 8 abuts against the limiting baffle 51, thus clamping the billet and ensuring that the position of the billet 8 is stable during the forging process, thereby improving the dimensional accuracy of the forging. Example 2

[0031] Based on the above embodiment 1, please refer to Figure 3 as well as Figure 4 The upper mold assembly 3 includes an upper mold 31. The surface of the upper mold 31 is provided with a limiting groove 311. The limiting groove 311 and the limiting baffle 51 are symmetrically arranged and slidably engaged. The locking block 52 is symmetrically provided with a locking groove 312 above it and is slidably engaged. Specifically, the limiting baffle 51 and the locking block 52 can seal and fit with the limiting groove 311 and the locking groove 312 of the upper mold 31 while limiting the blank, thus preventing the blank 8 from flowing in.

[0032] The upper mold groove 313 is provided on the outside of the limiting groove 311, and the lower mold groove 412 is symmetrically provided below the upper mold groove 313. Specifically, when the upper mold groove 313 and the lower mold groove 412 overlap, a complete mold cavity is formed to shape the forging.

[0033] The upper mold 31 is welded to the top of the upper mold base 32, and the lower mold 41 is welded to the lower mold base 42. Both the upper mold base 32 and the lower mold base 42 are provided with a heating cavity 71 at one end.

[0034] A hydraulic column 33 is welded to the top of the upper mold base 32. The top of the hydraulic column 33 is connected to a hydraulic cylinder 34. The hydraulic cylinder 34 is connected to a solenoid valve 35 through an oil pipe. The solenoid valve 35 is electrically connected to the control console 2. Specifically, the solenoid valve 35 controls the cylinder 34 to drive the hydraulic column 33 to extend and retract, thereby controlling the upper mold base 32 to rise and fall and drive the mold to complete isothermal forging.

[0035] The temperature control assembly 7 includes a temperature controller 72, which is electrically connected to a heating wire 73. The heating wire 73 is connected to a heating plate 74, which is installed inside the heating chamber 71.

[0036] In this embodiment, the temperature controller 72 precisely controls the upper and lower dies and the billet 8 to reach a suitable constant temperature. The temperature controller 72 heats the heating plate 74 through the heating wire 73 to ensure uniform die temperature. This achieves isothermal heating of the upper and lower dies to avoid uneven structure and stress concentration caused by temperature changes, which is beneficial to improving the quality and performance of the forging.

[0037] The working principle and usage process of this utility model are as follows: First, the blank 8 is placed inside the lower mold groove 412 on the surface of the lower mold 41. The length parameters of the rectangular blank 8 are input through the control console 2, and the equipment is started. The control console 2 controls the servo motor 54 to rotate according to the parameters. The servo motor 54 drives the spiral column 53 to rotate. The spiral column 53 interacts with the locking block 52. Through the spiral force, the locking block 52 slides on the surface of the sealing groove 412 and pushes the blank 8 until the other end of the blank 8 abuts against the limiting baffle 51, forming a stable clamping of the blank and realizing the precise positioning of the blank.

[0038] Subsequently, the control console 2 controls the solenoid valve 35 to cause the hydraulic cylinder 34 to move. The hydraulic cylinder 34 drives the hydraulic column 33 to extend, which in turn drives the upper mold base 32 to move downward. The upper mold base 32 drives the limiting groove 311 of the upper mold 31 to engage and slide with the lower limiting baffle 51. At the same time, the slot 312 engages and slides with the lower locking block 52, so that when the upper mold groove 313 and the lower mold groove 412 overlap, a sealed mold cavity is formed inside.

[0039] When the upper and lower dies extrude the billet 8, the control console 2 precisely controls the upper and lower dies and the billet to reach a suitable constant temperature through the temperature controller 72. The temperature controller 72 heats the heating plate 74 through the heating wire 73 to ensure uniform die temperature and achieve isothermal heating of the upper and lower dies. This keeps the constant temperature below the β transformation temperature of the titanium alloy, which can keep the titanium alloy billet in a good plastic state, reduce its deformation force, and avoid uneven structure and stress concentration caused by temperature changes. This is beneficial to improving the quality and performance of the forging.

[0040] Finally, the blank 8 flows into the mold cavity under the extrusion of the upper mold 31 and the lower mold 41 to complete the shaping. When the upper mold 31 and the lower mold 41 collide and generate impact force, the lower mold 41 drives the buffer plate 61 to move down through the lower mold base 42 and compresses the buffer spring 62 to buffer the impact force and avoid long-term hard collision between the upper mold 31 and the lower mold 41 causing mold damage.
