Description

Technical Field

[0001] This invention relates to the field of die forging technology, specifically to a synchronous rotary workpiece ejection and unloading device for multi-directional die forging. Background Technology

[0002] Multi-directional forging is a precision forging process that uses multi-directional pressure to plastically form metal billets in a closed mold along multiple directions. It can form complex structural parts such as complex cavities, internal threads, and polygonal grooves in one step. It has advantages such as high forming accuracy, high material utilization, and excellent mechanical properties, and is widely used in the manufacturing of high-end parts in machinery, automobiles, aerospace and other industries.

[0003] In multi-directional die forging, the die needs to work with the core to complete the rotary forging and forming. After forming, the workpiece needs to be ejected from the die quickly. However, workpieces with complex cavities are more prone to sticking to the die, requiring manual demolding. The degree of automation is low, and situations such as jamming and demolding failure are likely to occur.

[0004] For example, a publicly available patent document (publication number CN121491262A) discloses a multi-directional forging device for heavy-duty vehicle hangers, including a workbench, an upper die assembly, and a lower die table. A multi-directional punch mechanism and a cooling gas injection assembly are arranged circumferentially on the outer side of the lower die table. The multi-directional punch mechanism includes a rotating unit and multiple horizontal punch assemblies. The rotating unit is located on the outer wall of the lower die table and connected to each horizontal punch assembly. During the downward movement of the upper die assembly, it drives all horizontal punch assemblies to synchronously feed radially, extruding the hanger blank from the side into the cavity, achieving coordinated multi-directional forging with the upper die. The cooling gas injection assembly is connected to the horizontal punch assemblies.

[0005] Taking the aforementioned multi-directional die forging device as an example, complex cavity forming of workpieces can easily lead to sticking to the mold, and manual demolding is required inside the complex equipment. However, the friction between the billet and the inner wall of the mold is large, making demolding difficult. Scratches and deformations are easily generated during demolding, affecting the quality of the workpiece. Summary of the Invention

[0012] Preferably, the top material control assembly includes a hydraulic cylinder four and a telescopic rod fixedly installed on the outside of the processing table.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When this application is used, it controls the operation of multiple snap-fit ​​components, changes the transmission state of the ejector frame, and transforms the ejector frame from the state of driving the mold to rotate to the ejector structure that demolds the blank from inside the mold. This avoids the structure of the blank demolding affecting the rotation drive of the mold, making the blank demolding quick and simple.

[0018] 2. When using this application, after the billet is demolded, the multiple small oil outlet holes on the outside of the ejector frame are located at the top of the mold cavity. After the pump in the liquid supply assembly is activated, lubricating oil is supplied to the interior of the multi-faceted column. The lubricating oil enters the interior of the ejector frame and is sprayed out through the multiple small oil outlet holes connected to the interior of the ejector frame. At the same time, the hydraulic cylinder four is activated to push the mounting bracket two and the ejector frame downward. At this time, the multiple small oil outlet holes move downward, spraying lubricating oil into the interior of the mold, reducing the friction generated during the forging process of the billet inside the mold, reducing the difficulty of billet demolding, and reducing scratches on the outside of the billet. 3. When this application is used, after the ejector frame moves down and aligns the oil outlet hole with the bottom of the mold cavity, the hydraulic cylinder four pauses for a period of time, allowing excess lubricating oil inside the mold to enter the ejector frame through multiple oil outlet holes. Then, the hydraulic cylinder four resumes operation to reset the ejector frame. At this time, the oil outlet hole is blocked by the mold, and the excess lubricating oil is stored inside the ejector frame and the waste oil storage chamber. Through the setting of multiple oil outlet holes, floating box, pressure relief valve, and other structures, lubricating oil is sprayed into the mold during the ejector frame demolding process. This not only allows the excess lubricating oil inside the mold to be recycled into the sealed space for reuse, but also prevents the clean lubricating oil waiting to be used from being contaminated, thus controlling the cost of automatic demolding of the blank.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Figures 1-13 As shown, the present invention provides a synchronous rotary workpiece ejection and unloading device for multi-directional die forging, including a processing table 11 and a mold 12. A rotating platform 16 is rotatably embedded on the top of the processing table 11, and an ejector frame 18 is inserted into the bottom of the mold 12. Multiple receiving slots 19 are opened on the outer side of the rotating platform 16, and a snap-fit ​​component is provided inside the receiving slots 19. An ejector control component is connected between the ejector frame 18 and the processing table 11. Multiple small oil outlet holes 24 are opened on the top of the outer side of the ejector frame 18. A multi-faceted column 25 passes through the ejector frame 18. A transmission component is provided between the multi-faceted column 25 and the processing table 11. A connecting pipe 35 is fixedly installed at the bottom of the multi-faceted column 25. A backflow bend 36 is rotatably installed on the outer side of the connecting pipe 35. One end of the backflow bend 36 is connected to a liquid supply component. The liquid supply component includes an oil storage tank 45 fixedly connected to the bottom of the processing table 11. A solenoid valve 42 is fixedly installed on one side of the oil storage tank 45. A liquid extraction bend 46 is fixedly connected to the water inlet end of the solenoid valve 42. The liquid extraction bend 46 is located inside the oil storage tank 45. A liquid extraction pump 41 is installed on one side of the oil storage tank 45. The water outlet end of the solenoid valve 42 is fixedly connected to the water inlet end of the liquid extraction pump 41. A diversion box 37 is fixedly connected to the water outlet end of the liquid extraction pump 41. One end of the backflow bend 36 is fixedly connected to the bottom of the inner cavity of the diversion box 37. Two fixed brackets 43 are fixedly connected between the top of the diversion box 37 and the processing table 11. Multiple spring telescopic rods 39 are fixedly inserted through the bottom of the diversion box 37. A floating box 38 is fixedly connected between the piston ends of the multiple spring telescopic rods 39. The floating box 38 is slidably disposed inside the diversion box 37. A pressure relief valve 40 is fixedly inserted through the floating box 38.

[0023] Specifically, such as Figure 1 and Figure 2 A hydraulic cylinder 2 is fixedly mounted on a fixed frame 1 at the top of the processing table 11. A core 4 and multiple mounting brackets 6 are fixedly connected to the bottom of a fixed frame 3 that is fixedly connected to the piston end of the hydraulic cylinder 2. A core 5 is rotatably mounted on the outside of the core 4. The core 5 can continue to rotate.

[0024] The rolling ball 7, which is rolled at the bottom of the mounting bracket 16, abuts against the top of the core 2 5. Multiple mounting brackets 16 and multiple rolling balls 7 support the core 2 5. The rolling ball 7 can roll without affecting the rotation of the core 2 5. A fixing bracket 3 8 is fixedly connected between two mounting brackets 16. A friction plate 10 is fixedly connected to the piston end of a hydraulic cylinder 2 9 fixedly installed on the fixing bracket 3 8. The side of the friction plate 10 facing the core 2 5 is rough. Controlling the hydraulic cylinder 2 9 to work pushes the friction plate 10 against the core 2 5. The friction plate 10 limits the core 2 5 and cannot rotate.

[0025] By controlling the operation of hydraulic cylinder 2, the lower movement of core 4 and core 5 can be controlled, thus controlling their vertical positions.

[0026] Specifically, such as Figure 1 and Figure 3 Both sides of the top of the rotating table 16 are fixedly installed with a four-fixed frame 15. The piston end of the hydraulic cylinder three 13 fixedly installed on the top of the four-fixed frame 15 is fixedly installed with a core three 14. The hydraulic cylinder three 13 controls the core three 14 to move into the mold 12. The core four 17 fixedly connected to the top of the ejector frame 18 is set inside the mold 12.

[0027] Specifically, such as Figure 4 , Figure 7 and Figure 9 The rotating table 16 has multiple storage slots 19 on its outer side. The pneumatic cylinder 20 in the snap-fit ​​assembly is located inside the storage slot 19 at the end away from the top material frame 18. The outer wall of the pneumatic cylinder 20 is fixedly connected to the rotating table 16. A spring telescopic rod 21 is fixedly connected to the piston end of the pneumatic cylinder 20. The spring telescopic rod 21 can extend and retract. A drive shaft 22 is fixedly connected to the piston end of the spring telescopic rod 21. The top material frame 18 passes through the rotating table 16. The top material frame 18 can move up and down when it is not restricted. Multiple snap-fit ​​slots 23 are provided on the outer side of the top material frame 18. The snap-fit ​​slots 23 correspond one-to-one with the drive shaft 22.

[0028] The control cylinder 20 operates to push the spring telescopic rod 21 and the drive shaft 22 toward the top material frame 18. When the drive shaft 22 is aligned with the locking groove 23, one end of the drive shaft 22 is directly inserted into the locking groove 23. When the drive shaft 22 is misaligned with the top material frame 18, the drive shaft 22 abuts against the top material frame 18, the spring telescopic rod 21 retracts, and then the control cylinder 18 slowly rotates. When the drive shaft 22 is aligned with the locking groove 23, the rebounding spring telescopic rod 21 pushes one end of the drive shaft 22 directly into the locking groove 23.

[0029] Therefore, by controlling the operation of multiple snap-fit ​​components, multiple drive shafts 22 are ultimately inserted into multiple snap-fit ​​slots 23. The multiple drive shafts 22 are snapped between the rotating table 16 and the top material frame 18. At this time, the rotation of the top material frame 18 drives the rotation of the rotating table 16 through the multiple drive shafts 22. The multiple snap-fit ​​components serve as the transmission structure between the top material frame 18 and the rotating table 16, enabling the two to rotate synchronously.

[0030] The pneumatic cylinder 20 is controlled to operate, so that the drive shaft 22 is completely removed from the inside of the snap-fit ​​groove 23, and the interference between the rotation and up-and-down movement of the top material frame 18 and the rotating table 16 is eliminated.

[0031] Specifically, such as Figure 1 , Figure 5 and Figure 7 The top material control component includes a hydraulic cylinder 33 and a telescopic rod 34 fixedly mounted on the outside of the processing table 11. A mounting frame 32 is fixedly connected between the piston end of the hydraulic cylinder 33 and the piston end of the telescopic rod 34. The mounting frame 32 is rotatably mounted on the outside of the top material frame 18. The mounting frame 32 drives the top material frame 18 to move up and down. The mounting frame 32 does not obstruct the rotation of the top material frame 18. Support beams 44 are provided on both sides of the bottom of the mounting frame 32. The support beams 44 are fixedly connected to the processing table 11 and support the bottom of the mounting frame 32. The downward force on the top material frame 18 is directly applied to the processing table 11 through the support beams 44, providing protection for the transmission components.

[0032] Specifically, such as Figure 5 In the transmission assembly, the forward and reverse motor 31 and the gearbox 29 are both fixedly installed at the bottom of the processing table 11. The output end of the forward and reverse motor 31 is fixedly connected to the input end of the gearbox 29. The output end of the gearbox 29 is fixedly connected to the transmission shaft 28, and a brake 30 is sleeved on the outside. The brake 30 is fixedly installed at the bottom of the gearbox 29. The brake 30 is controlled to work to brake the transmission shaft 28, and the transmission shaft 28 is stopped from rotating.

[0033] Gear 27 is fixedly installed on the bottom outer side of the drive shaft 28. Gear 26 meshing on one side of gear 27 is fixedly installed on the outer side of the multi-faceted column 25. The multi-faceted column 25 is inserted into the top material frame 18. The top material frame 18 can move up and down on the outer side of the multi-faceted column 25 to control the operation of the forward and reverse motor 31. The forward and reverse motor 31 drives the multi-faceted column 25 to rotate through the gearbox 29, drive shaft 28, gear 27, and gear 26. The multi-faceted column 25 drives the top material frame 18 to rotate.

[0034] Therefore, the control transmission assembly is activated, and the top material frame 18 is driven to rotate.

[0035] Specifically, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 In the liquid supply assembly, the oil storage tank 45 is fixedly installed at the bottom of the processing table 11. The water inlet end of the solenoid valve 42 fixedly installed on one side of the oil storage tank 45 is fixedly connected to the liquid extraction bend 46. The liquid extraction bend 46 is located inside the oil storage tank 45. A liquid extraction pump 41 is provided on one side of the oil storage tank 45. The water outlet end of the solenoid valve 42 is fixedly connected to the water inlet end of the liquid extraction pump 41 to control the operation of the liquid extraction pump 41. The liquid extraction pump 41 extracts lubricating oil from inside the oil storage tank 45 through the solenoid valve 42 and the liquid extraction bend 46.

[0036] The outlet of the liquid pump 41 is fixedly connected to a diversion box 37. One end of the backflow bend 36 is fixedly connected to the bottom of the diversion box 37. Two fixing brackets 43 are fixedly connected between the top of the diversion box 37 and the processing table 11. The positions of the diversion box 37 and the backflow bend 36 are fixed.

[0037] Multiple spring telescopic rods 39 are fixedly inserted through the bottom of the diversion box 37. A floating box 38, which is fixedly connected between the piston ends of the multiple spring telescopic rods 39, is slidably disposed inside the diversion box 37. A pressure relief valve 40 is fixedly inserted through the floating box 38. When the pressure relief valve 40 is not open, the diversion box 37 and the pressure relief valve 40 move up and down inside the diversion box 37.

[0038] The pump 41 delivers lubricating oil into the distribution box 37. After the lubricating oil enters the top of the distribution box 37, the hydraulic pressure at the top of the distribution box 37 increases, causing the floating box 38 and the pressure relief valve 40 to move downwards. When the floating box 38 moves to its limit, the downward movement of the pressure relief valve 40 is restricted, and the bottom of the pressure relief valve 40 abuts against the bottom of the distribution box 37. The outlet end of the pressure relief valve 40 is inserted into the backflow bend 36. As the hydraulic pressure at the top of the distribution box 37 increases, the pressure relief valve 40 is opened by the lubricating oil, and the lubricating oil enters the backflow bend 36. The backflow bend 36 is connected to the interior of the multifaceted column 25 through the connecting pipe 35, and the lubricating oil enters the interior of the multifaceted column 25.

[0039] Therefore, after the liquid pump 41 in the control liquid supply assembly is working, it delivers lubricating oil into the interior of the multi-faceted column 25. The lubricating oil enters the interior of the top material rack 18 and is sprayed out through multiple small oil outlet holes 24 that are connected to the interior of the top material rack 18.

[0040] In summary, the multi-directional forging device consists of a processing table 11, a mold 12, a rotating table 16, an ejector frame 18, multiple snap-fit ​​components, an ejector control component, multiple oil outlet holes 24, a multi-faceted column 25, a transmission component, a connecting pipe 35, a backflow bend 36, and a liquid supply component. The working principle of the multi-directional forging device is as follows: The blank is placed inside the mold 12. Then, hydraulic cylinder 12 pushes core 14 and core 25 downwards. Once core 25 enters the mold 12, hydraulic cylinder 29 retracts, moving friction plate 10 away from core 25, allowing core 25 to rotate. Subsequently, multiple snap-fit ​​components are controlled to operate, and the forward and reverse motors 31 in the transmission assembly rotate forward, causing the ejector frame 18 to rotate clockwise. The ejector frame 18 first rotates slowly once and then rotates rapidly. The ejector frame 18 drives the rotating table 16 to rotate via multiple snap-fit ​​components. The mold 12 and two hydraulic cylinders 13 rotate, the mold 12 drives the core 5 to rotate, and the rotation of the mold 12 drives the blank to rotate, so that the core 4 forms a threaded groove on the blank. During the downward movement of the core 4, the hydraulic cylinders 13 are controlled to work and push the core 14. The core 14 forms a cavity on the outside of the blank. As the blank is subjected to the downward thrust applied by the core 5, the core 4 17 forms a polygonal groove on the blank. When the core 4, core 5 and two hydraulic cylinders 13 move to the preset position, the multi-directional forging device stops working and the blank forging is completed.

[0041] When it is necessary to unload the blank, the hydraulic cylinder 313 drives the core 314 to reset, so that the blank moves upward without obstruction. Then, the forward and reverse motor 31 in the transmission assembly is controlled to work in reverse. At this time, the ejector 18 rotates counterclockwise, the rotating table 16 and the mold 12 rotate counterclockwise, and the blank rotates counterclockwise. At the same time, the hydraulic cylinder 12 is controlled to work to drive the core 4 to move upward. At this time, the direction of the blank rotation is the direction in which the blank rotates and separates from the outside of the core 4. Under the influence of the core 4, the rotating blank is subjected to a force away from the core 5. Therefore, as the core 4 moves upward, the blank rotates and separates from the core 4 and stays inside the mold 12, completing the separation effect of the blank from the core 4. The blank stays inside the mold 12.

[0042] When core 1 4 and core 2 5 move up to the preset distance, the transmission assembly stops working, hydraulic cylinder 2 9 works to brake core 2 5 so that it cannot rotate, brake 30 works to brake transmission shaft 2 28, multi-faceted column 25 is braked, and ejector 18 is braked so that it cannot rotate. Subsequently, multiple snap-fit ​​components stop working, allowing ejector 18 to move up and down. Control hydraulic cylinder 4 33 works to drive mounting bracket 2 32 to move up, mounting bracket 2 32 drives ejector 18 to move up, and ejector 18 pushes the blank to move up and away from the mold 12, completing the separation of the blank from the mold 12.

[0043] By controlling the operation of multiple snap-fit ​​components, the transmission state of the ejector 18 is changed, so that the ejector 18 changes from the state of driving the mold 12 to the state of ejecting the blank from the inside of the mold 12. This avoids the blank ejection structure affecting the rotation drive of the mold 12, making blank ejection quick and simple. The transmission state can be switched with one key by switching the snap-fit ​​components on and off. It does not add extra mechanisms or occupy space. It does not interfere with the rotation molding of the blank during rotation molding, and there is no jamming when the blank is ejected.

[0044] After the billet is demolded, the multiple oil outlet holes 24 on the outside of the ejector frame 18 are located at the top of the inner cavity of the mold 12. After the pump 41 in the liquid supply assembly is activated, lubricating oil is supplied to the interior of the multi-faceted column 25. The lubricating oil enters the interior of the ejector frame 18 and is sprayed out through the multiple oil outlet holes 24 that are connected to the interior of the ejector frame 18. At the same time, the hydraulic cylinder 33 is activated to push the mounting bracket 32 ​​and the ejector frame 18 downward. At this time, the multiple oil outlet holes 24 move downward, spraying lubricating oil into the interior of the mold 12, reducing the friction generated during the forging process of the billet inside the mold 12, reducing the difficulty of billet demolding, and reducing scratches on the outside of the billet. After the pump 41 has been working for a period of time, it stops working, the top of the floating box 38 and the pressure relief valve 40 are hydraulically lowered, and the multiple spring telescopic rods 39 rebound and push the floating box 38 upward, so that the flow box 37 is filled with lubricating oil. When the ejector 18 moves down and aligns the oil outlet 24 with the bottom of the inner cavity of the mold 12, the hydraulic cylinder 33 pauses for a period of time, allowing excess lubricating oil inside the mold 12 to enter the ejector 18 through multiple oil outlets 24. Then, the hydraulic cylinder 33 resumes operation to reset the ejector 18. At this time, the oil outlet 24 is blocked by the mold 12, and the excess lubricating oil is stored inside the ejector 18 and the waste oil storage cavity. Through the design of multiple oil outlets 24, floating box 38, pressure relief valve 40, etc., lubricating oil is sprayed into the mold 12 during the ejector 18 demolding process. This not only allows the excess lubricating oil inside the mold 12 to be recycled into the sealed space for reuse, but also prevents the clean lubricating oil waiting to be used from being contaminated, thus controlling the cost of automatic demolding of the blank.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
