Description

Technical Field

[0001] The present invention relates to the technical field of hot forging die sets, and particularly to a hot forging die set for aviation components. Background Art

[0002] The forging process carried out above the metal recrystallization temperature is called hot forging, also known as hot die forging. During forging, the deformed metal flows violently, and the contact time between the forging and the die is relatively long. Therefore, it is required that the die material has high thermal stability, high-temperature strength and hardness, impact toughness, heat fatigue resistance and wear resistance and is easy to process. Low-alloy steel can be used to manufacture hot forging dies with relatively light working loads. The hot forging process precisely controls parameters such as temperature, pressure, and strain rate to achieve precise control of the shape and size of metal parts. The high-temperature effect also helps to eliminate residual stresses and defects inside the material, improve the material density and mechanical properties of the parts. The surface finish of hot forgings is high, without burrs and cracks, and can meet the high surface quality requirements without additional machining. During hot forging, after the blank is heated to a high temperature, during the hot forging process, oxide scale is likely to appear on the surface. After the oxide scale is pressed into the part during hot forging, it is easy to cause defects in the part. Although the blank will be descaled before being added to the forging equipment, new oxide scale will still be formed on the blank during the forging process. Moreover, in the existing forging die sets, the blank will continuously contact the lower die during forging, making it inconvenient to clean the new oxide scale formed on the lower surface of the blank during forging. There is a need for a hot forging die set for aviation components. Summary of the Invention

[0003] The purpose of the present invention is to provide a hot forging die set for aviation components to solve the problems raised in the above background art.

[0014] Furthermore, the driving mechanism includes a driving motor, a transmission shaft, and a connecting frame. The transmission shaft is rotatably connected to the top end of the annular frame. The connecting frame is fixedly connected to one end face of the rotary frame. A transmission connection is provided between the transmission shaft and the connecting frame. The driving motor is fixedly installed on the main support frame, and a transmission connection is provided between the output end of the driving motor and the other end of the transmission shaft.

[0015] Furthermore, an impact module is arranged inside the push rod, and the impact module is used to strike the mounting seat when the rotary frame rotates.

[0016] Furthermore, the impact module includes an impact rod. A long groove is formed on the outer side wall of the other end of the push rod. The impact rod is slidably inserted into the adjacent push rod. A limiting rod is fixedly connected to the bottom end of the impact rod. A first guiding groove is formed on one side wall of the side closing plate. A wave section is formed on one side of the first guiding groove. The other parts of the first guiding groove except the wave section are arranged at equal intervals from the second guiding groove. Both ends of the limiting rod are slidably connected to the first guiding groove. An impact block is slidably connected to the inner wall of the other end of the push rod. A connecting spring is fixedly connected between the impact block and the other end of the impact rod. A core rod is fixedly connected to the other end of the impact rod, and the core rod is slidably inserted into the impact block.

[0017] Furthermore, a recessed groove is provided in the middle position of the inner wall of the annular frame. An air inlet nozzle is fixedly connected to the bottom end of the annular frame. The jetting assembly further includes an outer air ring, which is fixedly connected to the inner wall of the recessed groove. The air inlet nozzle is communicated with the inner wall of the outer air ring. An inner air ring is slidably connected to the inner wall of the outer air ring. Fixed ears are fixedly connected to both inner walls of the inner air ring. One end of the fixed ear is rotatably connected to a rotating seat, and one end of the rotating seat is fixedly connected to an exhaust nozzle.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Through the setting of the rotary opening and closing assembly, the driving mechanism drives the rotary frame to rotate. When the rotary frame rotates, it drives the two mounting seats to cycle open and close. When the two mounting seats revolve to the upper and lower positions, the two mounting seats move away from each other. When the mounting seats revolve from the upper and lower positions to the left and right side positions, the two mounting seats approach and close to each other, realizing multiple forging and shaping of the blank. And during forging, the blank is turned over on both sides. Furthermore, in cooperation with the jetting assembly, air is jetted onto the upper side of the blank and the molds in the mounting seats located at the upper end position, so as to alternately remove the scale on the two molds and the two sides of the blank, reducing the influence of the scale generated during forging on the parts.

[0022] Through the setting of the impact module, when the push rod deflects from the left side to the upper side, the push rod moves outward relative to the rotary frame, causing the two mounting seats to move away from each other and separate. At the same time, when the limiting rod enters the wave section, the limiting rod drives the impact rod to move back and forth along the axis of the push rod relative to the push rod, so that the impact rod drives the impact block to knock on the corresponding mounting seat through the connecting spring, facilitating knocking on the mounting seat deflected to the upper side position and facilitating the separation of the mounting seat deflected to the upper side position from the blank, avoiding the blank being stuck in the mounting seat.

Detailed implementation manners

[0032] 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.

[0033] Please refer to Figures 1 - 8, in the embodiment of the present invention, a hot forging die holder for aviation parts includes a main support frame 100, a driving mechanism 200, a guiding assembly 300, a rotary opening and closing assembly 400, and a jetting assembly 500. The guiding assembly 300 includes an annular frame 310 and two side closing plates 320. The two side closing plates 320 clamp the annular frame 310 and are fixed to each other by bolts. A second guiding groove 330 is formed between the annular frame 310 and the side closing plates 320. The main support frame 100 supports and fixes the annular frame 310. The rotary opening and closing assembly 400 includes a rotary frame 410. Two mounting seats 430 are slidably connected inside the rotary frame 410. Mounting grooves for mounting the die are formed inside the mounting seats 430. Push rods 440 are slidably connected to both ends of the rotary frame 410. One end of the push rod 440 is fixedly connected to the adjacent mounting seat 430, and the other end of the push rod 440 is slidably connected to the second guiding groove 330. The jetting assembly 500 is located inside the annular frame 310. The jetting assembly 500 includes two exhaust nozzles 550. The two exhaust nozzles 550 are respectively aligned with the mounting grooves on the two mounting seats 430. The driving mechanism 200 is used to drive the rotary frame 410 to rotate.

[0034] Specifically, the upper die and the lower die of the die are respectively installed in the mounting grooves of the mounting seats 430. The driving mechanism 200 drives the rotary frame 410 to rotate. When the rotary frame 410 rotates, it drives the two push rods 440 to revolve. When the push rods 440 revolve, the limit on the other end of the push rods 440 through the second guiding groove 330 enables the rotary frame 410 to revolve and drive the two mounting seats 430 to cycle open and close. When the two mounting seats 430 revolve to the upper and lower positions, the two mounting seats 430 deviate from each other. When the mounting seats 430 revolve from the upper and lower positions to the left and right side positions, the two mounting seats 430 approach and close to each other, realizing multiple forging and shaping of the blank, and turning the blank on both sides during forging. Furthermore, in cooperation with the jetting assembly 500, jets are blown to the upper side of the blank and the die inside the mounting seat 430 located at the upper end position, so as to alternately remove the scale on both sides of the two dies and the blank, reducing the influence of the scale generated during forging on the parts.

[0035] Embodiment 1:

[0036] As Figures 5 - 8As shown, in this embodiment, fixed seats 420 are fixedly connected to both ends of the inner side wall of the slewing frame 410. Slide bars 421 are fixedly connected between the four top corners of the two fixed seats 420. The mounting seat 430 is slidably sleeved on the multiple slide bars 421. The push rod 440 is slidably inserted into the fixed seat 420 at the adjacent end. The second guiding groove 330 includes closing portions 331 provided at both ends. The second guiding groove 330 includes opening portions 332 provided on both sides. The distance between the two closing portions 331 is greater than the distance between the two opening portions 332. The arc angle of the opening portion 332 is 90 degrees. The other end of the push rod 440 is fixedly connected with a sliding seat 441. Rollers 442 are rotatably connected to the bottom end and the top end of the sliding seat 441. The rollers 442 are located in the second guiding groove 330. The driving mechanism 200 includes a driving motor 230, a transmission shaft 220, and a connecting frame 210. The transmission shaft 220 is rotatably connected to the top of the annular frame 310. The connecting frame 210 is fixedly connected to one end face of the slewing frame 410. The transmission shaft 220 is drivingly connected to the connecting frame 210. The driving motor 230 is fixedly installed on the main support frame 100. The output end of the driving motor 230 is drivingly connected to the other end of the transmission shaft 220.

[0037] In this embodiment, through the arrangement of the closing portions 331 and the opening portions 332, when the rollers 442 at the other end of the push rod 440 are located at the opening portions 332, the two mounting seats 430 are in a closed state. When the other ends of the two push rods 440 are located on the closing portions 331, the two mounting seats 430 are in a separated state. And when the other ends of the two push rods 440 are located at the middle positions of the closing portions 331, the distance between the two mounting seats 430 is the largest. It is realized that when the slewing frame 410 rotates one circle, the two mounting seats 430 are cyclically opened and closed twice, so that the mounting seats 430 are alternately deflected to the upper position and separated from the blank, thereby facilitating jet cleaning of the mold cavity.

[0038] As Figures 4 - 6As shown, in this embodiment, an impact module 450 is provided inside the push rod 440. The impact module 450 is used to strike the mounting seat 430 when the slewing frame 410 rotates. The impact module 450 includes an impact rod 451. A long groove 444 is formed on the outer side wall of the other end of the push rod 440. The impact rod 451 is slidably inserted between the adjacent push rod 440. A limiting rod 452 is fixedly connected to the bottom end of the impact rod 451. A first guiding groove 321 is formed on one side wall of the side closing plate 320. A wavy section 322 is formed on one side of the first guiding groove 321. The other parts of the first guiding groove 321 except the wavy section 322 are arranged at equal intervals with the second guiding groove 330. The two ends of the limiting rod 452 are slidably connected to the first guiding groove 321. An impact block 455 is slidably connected to the inner wall of the other end of the push rod 440. A connecting spring 454 is fixedly connected between the impact block 455 and the other end of the impact rod 451. A core rod 453 is fixedly connected to the other end of the impact rod 451. The core rod 453 is slidably inserted between the impact block 455.

[0039] During specific implementation, the wavy section 322 is located at the upper left position of the first guiding groove 321. When the push rod 440 deflects from the left side to the upper side, the push rod 440 moves outward relative to the slewing frame 410, causing the two mounting seats 430 to move away from each other. At the same time, when the limiting rod 452 enters the wavy section 322, the limiting rod 452 drives the impact rod 451 to move back and forth along the axis of the push rod 440 relative to the push rod 440. Thus, the impact rod 451 drives the impact block 455 to strike the corresponding mounting seat 430 through the connecting spring 454, facilitating the striking of the mounting seat 430 deflected to the upper side position, and facilitating the separation of the mounting seat 430 deflected to the upper side position from the workpiece, avoiding the workpiece being stuck in the mounting seat 430.

[0040] Embodiment Two:

[0041] As Figures 4 - 8As shown, in this embodiment, an embedded groove 311 is formed in the middle position of the inner wall of the annular frame 310. An air inlet nozzle 312 is fixedly communicated with the bottom end of the annular frame 310. The jet assembly 500 further includes an outer air ring 510. The outer air ring 510 is fixedly connected to the inner wall of the embedded groove 311. The air inlet nozzle 312 is communicated with the inner wall of the outer air ring 510. An inner air ring 520 is slidably connected to the inner wall of the outer air ring 510. Fixed ears 530 are fixedly connected to both inner walls of the inner air ring 520. One end of the fixed ear 530 is rotatably connected to a rotating seat 540. One end of the rotating seat 540 is fixedly connected to an exhaust nozzle 550. A ball head 560 is slidably sleeved on one end of the exhaust nozzle 550. Ball socket seats 411 are fixedly connected to both sides of the rotary frame 410. The ball head 560 is movably sleeved with the adjacent ball socket seat 411. A hose is communicated between one end of the exhaust nozzle 550 and the inner wall of the inner air ring 520. Oblique guide frames 570 are fixedly connected to both ends of the inner wall of the inner air ring 520. A side support 443 is fixedly connected to one side of the sliding seat 441. One end of the side support 443 is slidably connected to the inner wall of the oblique guide frame 570. The oblique guide frame 570 is inclined. The distance between one end of the oblique guide frame 570 and the adjacent sliding seat 441 is less than the distance between the other end of the oblique guide frame 570 and the ball socket seat 411.

[0042] During specific implementation, through the settings of the outer air ring 510 and the inner air ring 520, it is convenient for the jet assembly 500 to revolve with the rotary frame 410. External gas is introduced into the exhaust nozzle 550 through the air inlet nozzle 312. At the same time, through the setting of the oblique guide frame 570, when the other end of the push rod 440 moves towards the rotary frame 410, the two mounting seats 430 approach each other. At the same time, the sliding seat 441 drives the inner air ring 520 to rotate through the side support 443 and the oblique guide frame 570. When the sliding seat 441 moves away from the inner air ring 520, the inner air ring 520 is driven to rotate relative to the rotary frame 410 through the side support 443 and the oblique guide frame 570. When the inner air ring 520 rotates relative to the rotary frame 410, the exhaust nozzle 550 is driven to rotate through the fixed ear 530, so as to adjust the angle of the exhaust nozzle 550. Furthermore, when the mounting seat 430 opens and closes and moves, it is convenient for the exhaust nozzle 550 to adjust the angle following the movement of the mounting seat 430, so that the corresponding exhaust nozzle 550 always aligns with the mounting groove on the mounting seat 430.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
