Description

Technical Field

[0001] This invention relates to the field of forging equipment, and more particularly to a forging equipment for processing bearings for new energy power equipment. Background Technology

[0002] Forging is a general term for forging and stamping. It refers to the forming process of applying pressure to a metal billet through forging machinery to cause plastic deformation, thereby obtaining a part of the desired shape.

[0003] The invention patent with publication number CN119407085A discloses an adjustable forging and punching device, including a forging mechanism, a quantitative oil supply mechanism, a lifting control mechanism, and a horizontal one-way unlocking mechanism. The forging mechanism includes a forging base, a forging workpiece, a forging arm, a square pressure block, and a compression oil supply component.

[0004] As can be seen from the existing technology, bottom openings in punches are mostly used for blind hole machining, where lubricating oil is discharged to meet the friction reduction requirements of blind hole forging. However, in bearing forging, through holes are mostly machined at high temperatures, and lubricating oil is generally not required. Instead, a release agent is needed to form a continuous and uniform isolation film at the contact point between the punch and the workpiece to prevent the punch from sticking to the inner wall of the hole during retraction. If existing punches with bottom openings are used, the release agent is discharged from the bottom. The high temperature of hot forging may cause the release agent to evaporate and become ineffective. Furthermore, it is difficult to replenish the release agent to the side wall during the retraction process, resulting in poor separation between the punch and the workpiece. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the punch does not separate effectively from the workpiece, and to propose a forging device for bearing processing in new energy power equipment.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a forging device for processing bearings of new energy power equipment, comprising a frame, a hydraulic push rod fixed to the top of the frame, a forging head fixed to the bottom of the hydraulic push rod, and a forging punch fixed to the bottom of the forging head, and further comprising:

[0007] The liquid inlet channel is located inside the forging punch and is fixed to an external conveying device. Multiple discharge channels are provided on the side wall of the forging punch, including a first channel and a second channel. Both the first channel and the second channel are connected to the liquid inlet channel, and the first channel is located below the second channel.

[0008] A control valve is fixed inside the liquid inlet channel and is positioned between the first channel and the second channel.

[0009] A drainage assembly includes a fixed cylinder with a sliding cavity and an expansion cavity inside. A sealing element is inserted into the sliding cavity. An elastic support assembly is provided on one side of the sealing element to provide elastic support for the sealing element, so that the sealing element seals the sliding cavity. The other end of the sealing element extends out of the sliding cavity.

[0010] Preferably, the sealing component includes a sliding plug, a sealing plug, and a trigger ball. The sliding plug is inserted into the sliding cavity, and the outer wall of the sliding plug is in sealing contact with the inner wall of the sliding cavity. The size of the sealing plug is larger than the opening size of the sliding cavity. A connecting ring is fixed between one end of the sliding plug and the sealing plug, and a connecting plate is fixed to the other end of the sliding plug. The trigger ball is rotatably connected to the connecting plate. Both the connecting plate and the sliding plug are hollow structures. The interiors of the connecting plate and the sliding plug are interconnected. A discharge hole is provided on the side wall of the connecting plate. A communicating groove is provided at the end of the sliding plug, which communicates with the interior of the connecting ring. Multiple through holes are provided on the side wall of the connecting ring.

[0011] When in use, first place the forging workpiece under the forging head in the frame body, and push the forging head down by starting the hydraulic push rod. The forging head drives the forging punch to descend, and the forging punch squeezes into the interior of the forging workpiece to perform the punching operation.

[0012] In the initial state, under the elastic force of the elastic support component, the surface of the trigger ball at the end of the sealing component is in a state of extending out of the side wall of the forging punch, and the sealing plug contacts and seals the end of the sliding cavity. As the forging punch enters the interior of the forging workpiece, the trigger ball is pushed into the interior of the sliding cavity by the workpiece. The trigger ball drives the connecting plate, sliding plug, and sealing plug to move as a whole, so that the sealing plug moves away from the end of the sliding cavity, thus exposing the connecting ring. At this time, the internal space of the connecting ring is connected to the interior of the expansion cavity through the through hole on its surface. Since the connecting ring is connected to the interior of the sliding plug and the connecting plate through the connecting groove, and the connecting plate is connected to the interior of the sliding cavity through the discharge hole, the expansion cavity and the sliding cavity are connected, and the sealing effect of the sealing component is canceled. At this time, the release agent can enter the expansion cavity and the sliding cavity from the liquid inlet channel, and finally flow out from the end of the sliding cavity and enter the contact surface between the extrusion punch and the workpiece. During the punching process, a continuous isolation film is formed. By opening multiple liquid discharge channels on the side wall of the extrusion punch, the uniformity of the isolation film can be ensured.

[0013] When forged workpieces are in a high-temperature state, as the contact time between the release agent and the high-temperature workpiece increases, the release agent in some locations may volatilize. To avoid the volatilization effect of high temperature on the release agent, this invention sets up a first channel and a second channel at different heights. The first channel can drain liquid throughout the entire process as the extrusion punch moves, ensuring the continuity of the release film formation. When the extrusion punch moves to the middle position of the workpiece height, the second channel located above begins to enter the workpiece. By setting up the second channel for secondary drainage, a secondary film is formed on the upper half of the volatile section of the hole wall, which helps to reduce the impact of volatilization.

[0014] Preferably, the elastic support assembly includes a bracket, which is fixed to the inner wall of the expansion cavity, and a first spring is fixed between the bracket and the sealing plug.

[0015] Specifically, under the pushing action of the first spring, the sealing plug always tends to move towards the side closer to the sliding cavity. When the trigger ball is pushed into the sliding cavity, the first spring is in a compressed state. When the forging punch is separated from the workpiece, the trigger ball loses its pushing action. The first spring can push the sealing plug towards the side closer to the sliding cavity to re-seal the sliding cavity. At the same time, the trigger ball can also be reset under the pushing action.

[0016] Preferably, the connecting plate has a cam inside, the cam is coaxially connected to the trigger ball, a sliding plate is provided on one side of the cam, the sliding plate is slidably connected to the inner wall of the connecting plate, a first piston disc is slidably connected inside the sliding plug, the first piston disc is in sealing contact with the inner wall of the sliding plug, a connecting pipe is fixedly connected between the first piston disc and the sliding plate, the two ends of the connecting pipe pass through the first piston disc and the sliding plate respectively, a first one-way valve is fixed inside the connecting pipe, a second one-way valve is fixed inside the communicating groove, and a second spring is fixed between the sliding plate and the sliding plug.

[0017] Preferably, a second piston disc is slidably connected to the inner wall of the sliding plug, the second piston disc is slidably sleeved on the outside of the connecting pipe, a third spring is fixed between the second piston disc and the first piston disc, a telescopic cover is fixed to the surface of the first piston disc, a first exhaust hole and a second exhaust hole are opened on the surface of the first piston disc located inside the telescopic cover, a third one-way valve is fixed in the first exhaust hole, and a microporous assembly is provided in the second exhaust hole.

[0018] Preferably, the microporous assembly includes a movable cylinder, which is inserted inside a second vent hole, and a through groove is formed in the middle of the second vent hole.

[0019] Preferably, a connecting frame is fixed on the outer wall of the first piston disc, the connecting frame has a clearance hole communicating with the through groove, a fourth spring is fixed between the connecting frame and the moving cylinder, the surface of the moving cylinder has an inclined surface, and a conical groove is formed on the inner wall of the second exhaust hole.

[0020] Preferably, the cam includes a connecting part and a sliding part. The connecting part is coaxially fixed with the trigger ball. The end face of the connecting part has a sliding surface. The sliding part is slidably connected to the sliding surface. A limit strip is fixed to the end of the sliding surface. A limit groove is formed on the surface of the sliding part. The limit strip is inserted into the limit groove. A fifth spring is fixed between the limit strip and the sliding part.

[0021] Preferably, the trigger ball comprises two hemispherical blocks, which are symmetrically arranged on both sides of the connecting plate, and the surfaces of the hemispherical blocks have friction surfaces.

[0022] Preferably, there are multiple first channels and multiple second channels, and the multiple first channels and second channels are arranged alternately.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] I. This invention establishes a first channel and a second channel at different heights. The first channel drains liquid throughout the entire process as the extrusion punch moves, ensuring the continuity of the release film formation. When the extrusion punch moves to the middle of the workpiece height, the upper second channel begins to enter the workpiece, performing secondary drainage and secondary film formation on the volatile upper part of the hole wall, thus reducing the impact of volatilization. During the return stroke of the extrusion punch, the control valve closes, stopping the supply of liquid to the lower first channel and stopping its drainage function. Meanwhile, the trigger ball in the second channel rotates in the opposite direction, driving the cam to rotate in the opposite direction. By improving the cam, its length is reduced during reverse rotation, thus reducing the cam's pushing distance. This allows the forging punch to move upward and drain a small amount of liquid during the process of separating from the workpiece. This reduces waste caused by excessive drainage and allows for timely replenishment of the release agent in areas where it has become ineffective due to volatilization.

[0025] Second, this invention discharges liquid by using a trigger ball to drive the cam to rotate, squeezing the liquid out of the storage space. This ensures that the amount of liquid discharged by the forging punch is the same at different speeds. Furthermore, when the forging punch descends slowly, the cam rotates slowly, resulting in a slow liquid discharge speed. When the forging punch descends quickly, the cam rotates quickly, resulting in a fast liquid discharge speed. This ensures that the liquid discharge speed is matched with the forging punch's moving speed, which in turn helps to ensure the uniformity of film formation and avoids situations where some areas have thick films and others have thin films.

[0026] Third, when the forging punch moves slowly, the effective pushing distance of the second piston disc is longer and the discharge volume is larger. By simultaneously increasing the discharge volume when the forging punch moves slowly, this invention helps to further reduce the impact of volatilization. Attached Figure Description

[0037] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0038] like Figures 1 to 9 The forging device shown is for processing bearings in new energy power equipment. It includes a frame 1, a hydraulic push rod 2 fixed to the top of the frame 1, a forging head 3 fixed to the bottom of the hydraulic push rod 2, and a forging punch 4 fixed to the bottom of the forging head 3. It also includes:

[0039] Liquid inlet channel 5 is opened inside the forging punch 4. Liquid inlet channel 5 is fixed to the external conveying device. Multiple discharge channels are opened on the side wall of the forging punch 4. The discharge channels include a first channel 6 and a second channel 7. Both the first channel 6 and the second channel 7 are connected to the liquid inlet channel 5. The first channel 6 is located below the second channel 7.

[0040] Control valve 8 is fixed inside the liquid inlet channel 5 and is located between the first channel 6 and the second channel 7.

[0041] The drainage assembly includes a fixed cylinder 9, which has a sliding cavity 10 and an expansion cavity 11 inside. A sealing element is inserted into the sliding cavity 10. An elastic support assembly is provided on one side of the sealing element. The elastic support assembly is used to provide elastic support for the sealing element so that the sealing element seals the sliding cavity 10. The other end of the sealing element extends out of the sliding cavity 10.

[0042] The sealing component includes a sliding plug 12, a sealing plug 13, and a trigger ball 14. The sliding plug 12 is inserted into the sliding cavity 10, and the outer wall of the sliding plug 12 is in sealing contact with the inner wall of the sliding cavity 10. The size of the sealing plug 13 is larger than the opening size of the sliding cavity 10. A connecting ring 15 is fixed between one end of the sliding plug 12 and the sealing plug 13, and a connecting plate 16 is fixed to the other end of the sliding plug 12. The trigger ball 14 is rotatably connected to the connecting plate 16. Both the connecting plate 16 and the sliding plug 12 are hollow structures. The interiors of the connecting plate 16 and the sliding plug 12 are interconnected. A discharge hole 17 is provided on the side wall of the connecting plate 16. A connecting groove 18 communicating with the interior of the connecting ring 15 is provided at the end of the sliding plug 12. Multiple through holes 19 are provided on the side wall of the connecting ring 15.

[0043] The trigger ball 14 includes two hemispherical blocks, which are symmetrically arranged on both sides of the connecting plate 16, and the surface of the hemispherical blocks has a friction surface.

[0044] Specifically, during use, the forged workpiece is first placed under the forging head 3 inside the frame 1. The forging head 3 is pushed down by starting the hydraulic push rod 2. The forging head 3 drives the forging punch 4 to descend. The forging punch 4 is squeezed into the interior of the forged workpiece to perform the punching operation.

[0045] In the initial state, under the elastic pushing action of the elastic support component, the surface of the trigger ball 14 at the end of the sealing member is in a state of extending out of the side wall of the forging punch 4, and the sealing plug 13 contacts and seals the end of the sliding cavity 10; as the forging punch 4 enters the interior of the forging workpiece, under the obstruction of the workpiece, the trigger ball 14 can be pushed into the interior of the sliding cavity 10, and the trigger ball 14 drives the connecting plate 16, the sliding plug 12, and the sealing plug 13 to move as a whole, thereby causing the sealing plug 13 to move away from the end of the sliding cavity 10, thus exposing the connecting ring 15. At this time, the internal space of the connecting ring 15 is connected to the expansion through the through hole 19 on its surface. The cavity 11 is internally connected. Since the connecting ring 15 is internally connected to the sliding plug 12 and the connecting plate 16 through the connecting groove 18, and the connecting plate 16 is internally connected to the sliding cavity 10 through the discharge hole 17, the expansion cavity 11 and the sliding cavity 10 are connected, thus eliminating the sealing effect of the sealing component. At this time, the release agent can enter the expansion cavity 11 and the sliding cavity 10 from the liquid inlet channel 5, and finally flow out from the end of the sliding cavity 10, entering the contact surface between the extrusion punch and the workpiece. During the punching process, a continuous isolation film is formed. By opening multiple liquid discharge channels on the side wall of the extrusion punch, the uniformity of the isolation film can be ensured.

[0046] When a forged workpiece is in a high-temperature state, as the contact time between the release agent and the high-temperature workpiece increases, the release agent in some locations may volatilize. To avoid the volatilization effect of high temperature on the release agent, this invention sets up a first channel 6 and a second channel 7 at different heights. The first channel 6 can drain liquid throughout the entire process as the extrusion punch moves, ensuring the continuity of the release film formation. When the extrusion punch moves to the middle position of the workpiece height, the second channel 7 located above begins to enter the workpiece. By setting up the second channel 7 for secondary drainage, a secondary film is formed on the upper half of the volatile section of the hole wall, which helps to reduce the impact of volatilization.

[0047] It should be noted that both the first channel 6 and the second channel 7 are equipped with drainage components. By setting drainage components, it can be ensured that the first channel 6 and the second channel 7 will not drain before entering the workpiece, thus avoiding waste. Furthermore, in order to avoid ineffective drainage and reduce waste, the present invention sets a control valve 8. During the return stroke of the extrusion punch, the control valve 8 is closed to stop the supply of liquid to the first channel 6 located below, thereby stopping the drainage function of the first channel 6.

[0048] As a further embodiment of the present invention, the elastic support assembly includes a bracket 20, which is fixed on the inner wall of the expansion cavity 11, and a first spring 21 is fixed between the bracket 20 and the sealing plug 13.

[0049] Specifically, under the pushing action of the first spring 21, the sealing plug 13 always tends to move towards the side closer to the sliding cavity 10. When the trigger ball 14 is pushed into the sliding cavity 10, the first spring 21 is in a compressed state. When the forging punch 4 is separated from the workpiece, the trigger ball 14 loses its pushing action. The first spring 21 can push the sealing plug 13 to move towards the side closer to the sliding cavity 10, and re-seal the sliding cavity 10. At the same time, the trigger ball 14 can also be reset under the pushing action.

[0050] As a further embodiment of the present invention, a cam 22 is provided inside the connecting plate 16. The cam 22 is coaxially connected to the trigger ball 14. A sliding plate 23 is provided on one side of the cam 22. The sliding plate 23 is slidably connected to the inner wall of the connecting plate 16. A first piston disc 24 is slidably connected inside the sliding plug 12. The first piston disc 24 is in sealed contact with the inner wall of the sliding plug 12. A connecting pipe 25 is fixedly connected between the first piston disc 24 and the sliding plate 23. The two ends of the connecting pipe 25 pass through the first piston disc 24 and the sliding plate 23 respectively. A first one-way valve 26 is fixed inside the connecting pipe 25. A second one-way valve 27 is fixed inside the connecting groove 18. A second spring 28 is fixed between the sliding plate 23 and the sliding plug 12.

[0051] Specifically, the side of the first piston disc 24 away from the cam 22 has a liquid storage space between it and the sliding plug 12. During the punching process, the trigger ball 14 is always in contact with the workpiece. During the descent of the forging punch 4, the trigger ball 14 rubs against the surface of the workpiece, thereby enabling the trigger ball 14 to rotate. The trigger ball 14 drives the cam 22 to rotate. During the rotation, the cam 22 can push the sliding plate 23, the connecting pipe 25, and the first piston disc 24 to move towards the expansion cavity 11, thereby reducing the liquid storage space. Under the obstruction of the second one-way valve 27, the liquid in the liquid storage space can only be discharged from the first one-way valve 26 at the position of the connecting pipe 25 into the interior of the connecting plate 16 and discharged from the discharge hole 17 on the side wall of the connecting plate 16.

[0052] As the cam 22 moves away from the sliding plate 23, the sliding plate 23, driven by the second spring 28, moves the connecting pipe 25 and the first piston disc 24 away from the second one-way valve 27, thereby increasing the liquid storage space and generating negative pressure. Under the action of negative pressure, the liquid inside the expansion chamber 11 can be drawn into the liquid storage space through the second one-way valve 27 to fill the liquid storage space.

[0053] It should be noted that the descent speed of the forging punch 4 needs to be adjusted according to the material of the workpiece. Some workpieces require a slower punching speed during forging, while others require a faster punching speed. This results in differences in the descent speed of the forging punch 4 for different workpieces. In order to ensure that the discharge volume is similar for different descent speeds and that the discharge speed is matched with the moving speed of the forging punch 4, this invention uses the trigger ball 14 to drive the cam 22 to rotate, squeezing out the liquid in the storage space to discharge the liquid. This ensures that the discharge volume of the forging punch 4 is the same at different speeds.

[0054] Furthermore, when the forging punch 4 descends slowly, the cam 22 rotates slowly, resulting in a slow extrusion and drainage speed. When the forging punch 4 descends quickly, the cam 22 rotates quickly, resulting in a fast extrusion and drainage speed. This ensures that the drainage speed matches the moving speed of the forging punch 4, which in turn helps to guarantee the uniformity of film formation and avoids situations where some areas have thick films and others have thin films.

[0055] As a further embodiment of the present invention, a second piston disc 29 is slidably connected to the inner wall of the sliding plug 12. The second piston disc 29 is slidably sleeved on the outside of the connecting pipe 25. A third spring 30 is fixed between the second piston disc 29 and the first piston disc 24. A telescopic cover 31 is fixed on the surface of the first piston disc 24. A first exhaust hole 32 and a second exhaust hole 33 are opened on the surface of the first piston disc 24 located inside the telescopic cover 31. A third one-way valve 34 is fixed in the first exhaust hole 32. A microporous assembly is provided in the second exhaust hole 33.

[0056] Specifically, when the forging punch 4 descends slowly, the release agent is in contact with the workpiece for a long time, requiring an increase in the amount of release agent discharged. This invention provides a second piston disc 29 on one side of the first piston disc 24, through which the liquid is pushed out. When the forging punch 4 moves slowly, the trigger ball 14 also moves slowly, which causes the cam 22 to push the sliding plate 23 to move slowly. At this time, the sliding plate 23 drives the connecting pipe 25 and the first piston disc 24 to move. There is a fourth spring 39 between the first piston disc 24 and the second piston disc 29. The first piston disc 24 drives the second piston disc 29 to perform the liquid pushing operation through the fourth spring 39.

[0057] Among them, the third one-way valve 34 is a pressure valve, which requires sufficient pressure to open. During the slow movement of the first piston disc 24, the pushing speed is relatively slow. The gas between the first piston disc 24 and the second piston disc 29 can be discharged through the microporous assembly to maintain the gas pressure balance. As a result, during the synchronous movement of the first piston disc 24 and the second piston disc 29, the distance between the first piston disc 24 and the second piston disc 29 gradually decreases.

[0058] When the first piston disc 24 moves quickly, the pressure between the first piston disc 24 and the second piston disc 29 increases sharply. Under the action of air pressure, the third one-way valve 34 can be opened immediately to exhaust the gas, thereby rapidly reducing the distance between the first piston disc 24 and the second piston disc 29. It can be seen that when the forging punch 4 moves slowly, the effective liquid pushing distance of the second piston disc 29 is longer and the liquid discharge volume is larger. This invention, by simultaneously increasing the liquid discharge volume when the forging punch 4 moves slowly, is beneficial to further reduce the impact of volatilization.

[0059] As a further embodiment of the present invention, the microporous assembly includes a movable cylinder 35, which is inserted inside the second exhaust hole 33, and a through groove 36 is provided in the middle of the second exhaust hole 33.

[0060] A connecting frame 37 is fixed on the outer wall of the first piston disc 24. A clearance hole 38 communicating with the through groove 36 is provided on the connecting frame 37. A fourth spring 39 is fixed between the connecting frame 37 and the moving cylinder 35. An inclined surface is provided on the surface of the moving cylinder 35. A conical groove 40 is provided on the inner wall of the second exhaust hole 33.

[0061] Specifically, when the first piston disc 24 moves slowly, gas can be discharged from the through groove 36. When the cam 22 disengages from the sliding plate 23, during the reset process of the first piston disc 24 and the second piston disc 29, under the pushing action of the fourth spring 39, the first piston disc 24 and the second piston disc 29 move away from each other. Since the inner diameter of the through groove 36 is small and the air intake speed is slow, in order to improve the air intake speed, the present invention sets a conical groove 40. Under the action of negative pressure, the moving cylinder 35 can be drawn to gradually move into the second vent hole until its inclined surface position moves into the conical groove 40. The gap generated between the inclined surface and the conical groove 40 can increase the gas entry position, thereby accelerating the entry speed.

[0062] As a further embodiment of the present invention, the cam 22 includes a connecting part 41 and a sliding part 42. The connecting part 41 is coaxially fixed with the trigger ball 14. The end face of the connecting part 41 has a sliding surface. The sliding part 42 is slidably connected to the sliding surface. A limit strip 43 is fixed at the end of the sliding surface. A limit groove 44 is formed on the surface of the sliding part 42. The limit strip 43 is inserted into the limit groove 44. A fifth spring 45 is fixed between the limit strip 43 and the sliding part 42.

[0063] Specifically, when the forging punch 4 moves downward, the trigger ball 14 rotates in the forward direction. At this time, the trigger ball 14 drives the connecting part 41 to rotate, and the connecting part 41 drives the sliding part 42 to move. When the sliding part 42 contacts the sliding plate 23, under the blocking action of the limit bar 43, the connecting part 41 can drive the sliding part 42 to move synchronously, thereby completing the pushing function.

[0064] When the forging punch 4 retracts, if the first channel 6 located above continues to drain liquid, it may lead to excessive liquid discharge. If the liquid discharge stops, it may be difficult to replenish the positions where the mold release agent has evaporated and failed in time. In this invention, when the forging punch 4 moves upward, the trigger ball 14 rotates in the opposite direction. At this time, the trigger ball 14 drives the connecting part 41 to rotate in the opposite direction. When the sliding part 42 contacts the sliding plate 23, the sliding part 42 slides on the sliding surface under the blocking action of the sliding plate 23, thereby reducing the length of the cam 22 and reducing the pushing distance of the cam 22. This allows the forging punch 4 to move upward and disengage from the workpiece, during which a small amount of liquid can be discharged. On the one hand, this can reduce the waste caused by excessive liquid discharge. On the other hand, by discharging a small amount of liquid, it can also replenish the positions where the mold release agent has evaporated and failed in time.

[0065] As a further embodiment of the present invention, there are multiple first channels 6 and multiple second channels 7, and the multiple first channels 6 and multiple second channels 7 are arranged alternately.

[0066] Specifically, the mold release agent located far from the drainage channel is more volatile than the mold release agent located near the liquid distribution channel. In this invention, the first channel 6 and the second channel 7 are staggered. After the liquid is drained from the upper second channel 7, it can replenish the isolation membrane between the adjacent first channel 6 below, which helps to reduce the volatilization of the mold release agent located far from the drainage channel and further improves the uniformity of the drainage between the upper and lower layers.

[0067] Working principle: When in use, the forging workpiece is first placed under the forging head 3 inside the frame 1. The hydraulic push rod 2 is activated to push the forging head 3 downward. The forging head 3 drives the forging punch 4 to descend. The forging punch 4 is squeezed into the interior of the forging workpiece to perform the punching operation.

[0068] In the initial state, under the elastic pushing action of the elastic support component, the surface of the trigger ball 14 at the end of the sealing member is in a state of extending out of the side wall of the forging punch 4, and the sealing plug 13 contacts and seals the end of the sliding cavity 10; as the forging punch 4 enters the interior of the forging workpiece, under the obstruction of the workpiece, the trigger ball 14 can be pushed into the interior of the sliding cavity 10, and the trigger ball 14 drives the connecting plate 16, the sliding plug 12, and the sealing plug 13 to move as a whole, thereby causing the sealing plug 13 to move away from the end of the sliding cavity 10, thus exposing the connecting ring 15. At this time, the internal space of the connecting ring 15 is connected to the expansion through the through hole 19 on its surface. The cavity 11 is internally connected. Since the connecting ring 15 is internally connected to the sliding plug 12 and the connecting plate 16 through the connecting groove 18, and the connecting plate 16 is internally connected to the sliding cavity 10 through the discharge hole 17, the expansion cavity 11 and the sliding cavity 10 are connected, thus eliminating the sealing effect of the sealing component. At this time, the release agent can enter the expansion cavity 11 and the sliding cavity 10 from the liquid inlet channel 5, and finally flow out from the end of the sliding cavity 10, entering the contact surface between the extrusion punch and the workpiece. During the punching process, a continuous isolation film is formed. By opening multiple liquid discharge channels on the side wall of the extrusion punch, the uniformity of the isolation film can be ensured.

[0069] When the extrusion punch moves to the middle position of the workpiece height, the second channel 7 located above begins to enter the workpiece. By setting the second channel 7, secondary drainage is carried out, and secondary film is formed on the volatile section of the upper half of the hole wall, which helps to reduce the impact of volatilization.

[0070] During the descent of the forging punch 4, the trigger ball 14 comes into frictional contact with the workpiece surface, thereby enabling the trigger ball 14 to rotate. The trigger ball 14 drives the cam 22 to rotate. During the rotation, the cam 22 can push the sliding plate 23, the connecting pipe 25, and the first piston disc 24 to move closer to the expansion cavity 11, thereby reducing the liquid storage space. Under the obstruction of the second one-way valve 27, the liquid in the liquid storage space can only be discharged from the first one-way valve 26 at the position of the connecting pipe 25 into the interior of the connecting plate 16, and discharged from the discharge hole 17 on the side wall of the connecting plate 16.

[0071] As the cam 22 moves away from the sliding plate 23, the sliding plate 23, driven by the second spring 28, moves the connecting pipe 25 and the first piston disc 24 away from the second one-way valve 27, thereby increasing the liquid storage space and generating negative pressure. Under the action of negative pressure, the liquid inside the expansion chamber 11 can be drawn into the liquid storage space through the second one-way valve 27 to fill the liquid storage space.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
