Description

Technical Field

[0001] This invention relates to the field of machine tool workpiece forging technology, specifically an automatic ejection structure and ejection method for machine tool slide rail forging products. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. Forging can eliminate defects such as casting porosity generated during the smelting process and optimize the microstructure. At the same time, because it retains complete metal flow lines, the mechanical properties of forgings are generally superior to those of castings made of the same material. Important parts in related machinery that are subject to high loads and harsh working conditions are mostly made of forgings, except for simpler shapes that can be made of rolled plates, profiles, or welded parts.

[0003] In particular, when forging compact forgings such as tool holders and machine tool slides, the surface of the finished forging parts has many grooves. At this time, the surface of the forged finished product is still in a state of high heat and easy deformation. When pushing out such forged finished products, the forged finished products are prone to sticking to the forging groove. Forcing them out at this time can easily cause scratches on the surface of the finished product, resulting in damage to the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic ejection structure and ejection method for machine tool slide rail forgings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic ejection structure for machine tool slide rail forgings includes: a forging press, wherein the forging press is provided with a forging groove and a hydraulic forging;

[0007] The forging press is also equipped with a lifting component and a pre-treatment component. During the lifting process of the hydraulic forging, the pre-treatment component is triggered to cool the forged product in the forging groove first, so that the forged product cools and shrinks, thereby making it easier for the lifting component to push the forged product out of the forging groove later.

[0008] The lifting assembly includes a drive structure, a lifting structure, and a pushing structure. The drive structure cooperates with the hydraulic forging component of the forging press. After the forged product cools, the hydraulic forging component drives the drive structure to move, thereby driving the lifting structure to push the forged product placed in the forging press out of the forging groove until the forged product is flush with the forging platform and maintains the same state. Then, the pushing structure is driven to push the forged product to slide along the forging platform so that the forged product is completely separated from the forging groove.

[0009] The automatic ejection structure for machine tool slide rail forgings as described above: the pretreatment component includes a water-cooling pipe disposed in the forging press, a triggering structure installed on the hydraulic forging, and a guide disposed on the forging press;

[0010] The outlet of the water-cooling pipe is connected to a water outlet component installed on the forging press, and the water outlet component is provided with a sealing structure. The sealing structure includes a sealing plate slidably installed on the water outlet component. A plug rod is provided on the side of the sealing plate away from the water outlet component. A sleeve is slidably installed on the plug rod. A moving rod is provided on the sleeve. The moving rod is connected to the guide component. During the rise of the hydraulic forging component, the triggering structure cooperates with the guide component to seal the water outlet component.

[0011] The automatic ejection structure of the machine tool slide rail forging as described above: the triggering structure includes a guide rail disposed on the hydraulic forging, a transverse plate elastically slidably disposed on the guide rail, a second mounting member disposed on the transverse plate, a second sliding rod formed on the second mounting member, the second sliding rod cooperating with the guide member, and being able to drive the sealing plate to slide relative to the water outlet member.

[0012] The automatic ejection structure for machine tool slide rail forgings as described above: the guide includes a guide plate disposed on the forging press, the guide plate is provided with a first fitting groove and a second fitting groove, the second slide rod is slidably disposed in the first fitting groove, the moving rod is slidably disposed in the second fitting groove, the first fitting groove includes a reset groove, a second inclined groove, a vertical groove and a horizontal groove disposed on the guide plate, and a deflection plate is elastically disposed at the connection between the second inclined groove and the reset groove.

[0013] The automatic ejection structure for machine tool slide rail forgings as described above: the second fitting groove includes a first locking groove, a first inclined groove and a second locking groove formed on the guide plate.

[0014] The automatic ejection structure for machine tool slide rail forgings as described above: the driving structure includes a moving plate and a first mounting component. The moving plate is slidably disposed on the forging press, the first mounting component is disposed on the hydraulic forging, and the first mounting component is provided with a first sliding rod. The first sliding rod is slidably disposed on a composite groove opened on the moving plate, the composite groove including a third inclined groove and a sliding groove.

[0015] The automatic ejection structure for machine tool slide rail forgings as described above: the lifting structure includes a lifting plate slidably disposed on the forging press, a series of support members adapted to the forging groove are equidistantly distributed on the lifting plate, and an installation plate is also provided on the lifting plate. The installation plate is provided with a guide groove, which includes a transverse groove, a fourth inclined groove, a stabilizing groove and a return groove provided on the installation plate. A baffle is elastically provided at the connection between the fourth inclined groove and the transverse groove.

[0016] The automatic ejection structure for machine tool slide rail forgings as described above: The pushing structure includes guide rods disposed on the forging press. Two sets of guide rods are disposed along the thickness direction of the moving plate. The two sets of guide rods are distributed on both sides of the forging groove. A second spring is sleeved on each set of guide rods. One end of the second spring abuts against the end of the guide rod, and the other end abuts against the pushing plate slidably disposed on the two sets of guide rods.

[0017] The automatic ejection structure for machine tool slide rail forgings as described above: the moving plate is further provided with a pusher, the pusher including an abutment plate provided on the moving plate, the abutment plate being provided with a third slide rod, the third slide rod being slidably disposed in the guide groove.

[0018] Correspondingly, an automatic ejection method for machine tool slide rail forgings is also proposed, employing the automatic ejection structure for machine tool slide rail forgings as described above, including the following steps:

[0019] Step 1: After the hydraulic forging of the part is completed, when it rises, the moving plate remains stationary at first. After a period of time, the moving plate slides along the axial direction of the guide rod.

[0020] Step 2: While the moving plate remains stationary, the second slide rod slides along the axial direction of the guide rod under the guidance of the first fitting groove. During this process, the second slide rod, in cooperation with the first fitting groove, drives the moving rod to rise, thereby blocking the water outlet so that the water cooling pipe can cool the forged finished product.

[0021] Step 3: During the subsequent movement of the moving plate, the third slide bar cooperates with the mounting plate to drive the lifting plate to rise, raising the forged product to be level with the forging platform and maintaining its state. Then, the moving plate continues to move and can push the push plate to slide along the axial direction of the guide rod, thereby separating the forged product from the forging groove.

[0022] Step 4: When the hydraulic forging part rises to its highest point, the forged product is completely separated from the forging groove. At this time, the lifting plate returns to its original position with the help of the mounting plate.

[0023] Step 5: When the hydraulic forging part descends again, the moving rod resets until the hydraulic forging part rises again. Repeat steps one to four to push the forging part out again.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] By setting up pretreatment and lifting components, during the lifting process of the hydraulic forging, the pretreatment component utilizes the cooperation between the triggering structure, the sealing structure, and the guide to automatically seal the outlet, allowing cooling water to enter and remain in the water-cooling pipe. During the sealing process, the third spring is compressed to store energy, which enhances the sealing pressure between the sealing plate and the outlet, ensuring that the cooling water remains in the water-cooling pipe without leakage, thereby improving cooling efficiency. Furthermore, when the cooling water uniformly cools the surface of the forged product, it can cause the contact surface between the forged product and the forging groove to quickly contract and form a gap, providing physical separation conditions for subsequent lifting and avoiding excessive ejection resistance or scratches on the surface of the finished product due to adhesion.

[0026] Furthermore, after the pretreatment component cools the surface of the forged product, the continuously rising hydraulic forging can drive the lifting component to move. During this process, the drive structure, lifting structure, and pushing structure cooperate to first lift the forged product to be level with the forging platform. After the lifting is completed, the pushing structure is used to push the forged product horizontally to ensure that the forged product is completely separated from the forging groove.

[0027] During the subsequent descent of the hydraulic forging, the first and second fitting grooves on the guide, in conjunction with the triggering structure and the sealing structure, can release the water outlet component so that each component returns to its initial position, allowing the forging product to be pushed out again.

[0028] The entire process requires no manual intervention. By utilizing the synergistic effect of mechanical linkage and physical cooling, it solves the problems of easy sticking and damage to finished products during the traditional forging and ejection process, and realizes the automated ejection of precision forgings such as machine tool slide rails.

[0042] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0043] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0044] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0045] Please see Figures 1-12 In this embodiment of the invention, an automatic ejection structure for machine tool slide rail forgings includes:

[0046] Forging press 1, the forging press 1 is provided with forging groove 101 and hydraulic forging 2;

[0047] Preferably, a forging blank is placed in the forging groove 101, and the hydraulic forging component 2 applies pressure to the blank in the forging groove 101 to cause plastic deformation, thereby obtaining a forged finished product of the required shape and size.

[0048] The forging press 1 is also equipped with a lifting component and a pre-treatment component. During the rise of the hydraulic forging 2, the pre-treatment component is triggered to cool the forged product in the forging groove 101 first, so that the forged product cools and shrinks, thereby facilitating the subsequent lifting component to push the forged product out of the forging groove 101.

[0049] The pretreatment assembly includes a water-cooled pipe 11 disposed in the forging press 1, a triggering structure installed on the hydraulic forging 2, and a guide disposed on the forging press 1;

[0050] Specifically, please refer to Figure 1 , Figure 2 The aforementioned water-cooling pipe 11 is spirally arranged around the forging groove 101. When water flows through the water-cooling pipe 11, the water-cooling pipe 11 can perform surface cooling on the forged product. At this time, the contact surface between the forged product and the forging groove 101 will generate a certain gap due to cooling contraction. This gap can facilitate the subsequent lifting assembly to lift the forged product out of the forging groove 101.

[0051] The outlet of the water-cooled pipe 11 is connected to the water outlet component 5 installed on the forging press 1, and the water outlet component 5 is provided with a sealing structure. The sealing structure includes a sealing plate 19 slidably installed on the water outlet component 5. A plug rod 10 is provided on the side of the sealing plate 19 away from the water outlet component 5. A sleeve 20 is slidably installed on the plug rod 10. A moving rod 15 is provided on the sleeve 20. The moving rod 15 is connected to the guide. During the rise of the hydraulic forging part 2, the triggering structure cooperates with the guide to seal the water outlet component 5.

[0052] For details, please refer to Figure 6 A locking block 2001 is formed on the inner wall of the aforementioned sleeve 20. The locking block 2001 is slidably disposed in the locking groove 1001 opened on the insertion rod 10. With the cooperation of the locking groove 1001, the locking block 2001 and the guide, the sleeve 20 can only move along the axial direction of the insertion rod 10. A third spring 29 is also sleeved on the insertion rod 10. One end of the third spring 29 abuts against the sleeve 20 and the other end abuts against the sealing plate 19. The subsequent triggering structure cooperates with the guide to increase the stored potential energy of the third spring 29 during the process of driving the sealing plate 19 to contact the water cooling pipe 11, so that the sealing plate 19 seals the water cooling pipe 11, ensuring that the cooling water remains in the water cooling pipe 11 to cool the forged product.

[0053] The aforementioned water-cooling pipe 11 is connected to a water pump located on the side (not shown in the figure). When the sealing plate 19 blocks the water outlet 5 with the cooperation of the trigger structure and the guide, the water pump starts synchronously and pumps cooling water into the water-cooling pipe 11. At this time, the cooling water remains in the water-cooling pipe 11 and can provide a certain degree of short-term cooling to the forged product (rapid cooling time is long and can easily cause cracks in the forged product), so that the forged product can be separated from the forging groove 101.

[0054] For details, please refer to Figures 1-8 The triggering structure includes a guide rail 24 disposed on the hydraulic forging 2, a transverse plate 16 elastically slidably disposed on the guide rail 24, a second mounting member 7 disposed on the transverse plate 16, a second sliding rod 701 formed on the second mounting member 7, the second sliding rod 701 cooperating with the guide member, and being able to drive the sealing plate 19 to slide relative to the water outlet member 5;

[0055] Specifically, the aforementioned transverse plate 16 is provided with a slider 1601, which is slidably disposed within the guide rail 24. With the cooperation of the slider 1601 and the guide rail 24, the transverse plate 16 can only slide along the length direction of the guide rail 24. The transverse plate 16 is also provided with a sleeve ring 1602, which is slidably connected to a fixing rod 17 disposed on the hydraulic forging 2. A first spring 18 is sleeved on the fixing rod 17, with one end of the first spring 18 abutting against the end of the fixing rod 17 and the other end abutting against the sleeve ring 1602.

[0056] Specifically, the first spring 18 is always in a compressed state, causing the transverse plate 16 to tend to move to the left (see reference). Figure 5 describe).

[0057] Further, please refer to Figure 7 The guide includes a guide plate 6 disposed on the forging press 1. The guide plate 6 has a first fitting groove and a second fitting groove. The second slide rod 701 is slidably disposed in the first fitting groove, and the moving rod 15 is slidably disposed in the second fitting groove. The first fitting groove includes a reset groove 2101, a second inclined groove 2102, a vertical groove 2103 and a horizontal groove 2104 disposed on the guide plate 6. A deflection plate 22 is elastically disposed at the connection between the second inclined groove 2102 and the reset groove 2101. In particular, in the initial state, the deflection plate 22 is parallel to the second inclined groove 2102, and the deflection plate 22 is connected to the guide plate 6 through a first spring piece 23 so that the deflection plate 22 can only deflect counterclockwise toward the direction of the second inclined groove 2102.

[0058] The second fitting groove includes a first locking groove 601, a first inclined groove 602 and a second locking groove 603 formed on the guide plate 6;

[0059] In the initial state, the second slide bar 701 is located at the connection between the horizontal groove 2104 and the reset groove 2101, and the moving rod 15 is located at the end of the stroke of the second locking groove 603. At this time, the water outlet of the water cooling pipe 11 is open.

[0060] In accordance with the above, during the upward movement of the hydraulic forging 2, the second slide rod 701 first slides within the reset groove 2101. At this time, the lifting plate 25, fixed to the second slide rod 701, can contact the moving rod 15. During this process, the rising second slide rod 701, in cooperation with the lifting plate 25, synchronously drives the moving rod 15 to slide within the second locking groove 603, so that the sealing plate 19 gradually contacts the outlet of the water-cooling pipe 11. After the second slide rod 701 rises a certain distance, the moving rod 15 contacts the first inclined groove 602, and the sealing plate 19 seals the water outlet 5. At this time, the water pump is turned on, pumping cooling water into the water-cooling pipe 11. Water is used to cool the surface of the forged product. As the second slide bar 701 continues to rise, the first inclined groove 602 forces the moving rod 15 to move the sleeve 20 closer to the sealing plate 19, so that the compression of the third spring 29 increases. During this process, the sealing plate 19 is always in the state of blocking the water outlet 5, and the third spring 29 reacts to the sealing plate 19, so that the squeezing force between the sealing plate 19 and the water outlet 5 increases, thereby continuously blocking the water outlet until the moving rod 15 contacts the first locking groove 601, the sealing plate 19 separates from the water outlet, the cooling water in the water cooling pipe 11 is discharged from the water outlet 5, and then the water pump is turned off.

[0061] Subsequently, the hydraulic forging 2 continues to rise, so that the second slide bar 701 moves past the deflection plate 22 to the end of the stroke of the reset groove 2101. At the same time, the moving rod 15 moves to the end of the stroke of the first locking groove 601. During this process, the hydraulic forging 2 cooperates with the lifting assembly to lift the forged product out of the forging groove 101.

[0062] Furthermore, please refer to Figures 1-5 , Figures 9-12 The lifting assembly includes a drive structure, a lifting structure, and a pushing structure. The drive structure cooperates with the hydraulic forging component 2 of the forging press 1. After the forged product cools, the hydraulic forging component 2 drives the drive structure to move, thereby driving the lifting structure to push the forged product placed in the forging press 1 out of the forging groove 101 until the forged product is flush with the forging platform and maintains the same state. Then, the pushing structure is driven to push the forged product to slide along the forging platform so that the forged product is completely separated from the forging groove 101.

[0063] The driving structure includes a movable plate 3 and a first mounting component 4. The movable plate 3 is slidably disposed on the forging press 1. The first mounting component 4 is disposed on the hydraulic forging component 2, and a first sliding rod 401 is disposed on the first mounting component 4. The first sliding rod 401 is slidably disposed on a composite groove opened on the movable plate 3. The composite groove includes a third inclined groove 301 and a sliding groove 302.

[0064] For details, please refer to Figure 10The aforementioned movable plate 3 is provided with a protrusion 303, which is slidably disposed in a groove opened on the forging press 1. With the cooperation of the protrusion 303 and the groove, the movable plate 3 can only slide along the length direction of the guide rail 24, so that the movable plate 3 can cooperate with the pushing structure to push the forged finished product onto the forging platform.

[0065] The lifting structure includes a lifting plate 12 slidably mounted on the forging press 1. A series of support members 1201, adapted to the forging groove 101, are equidistantly distributed on the lifting plate 12. An mounting plate 13 is also provided on the lifting plate 12. The mounting plate 13 has a guide groove, which includes a transverse groove 1301, a fourth inclined groove 1302, a stabilizing groove 1303, and a return groove 1304. A baffle 27 is elastically provided at the connection between the fourth inclined groove 1302 and the transverse groove 1301. Specifically, please refer to... Figure 12 The baffle 27 is parallel to the fourth inclined groove 1302, and the baffle 27 is connected to the mounting plate 13 through the second spring piece 28, so that the baffle 27 can only be deflected clockwise toward the fourth inclined groove 1302.

[0066] The pushing structure includes guide rods 8 disposed on the forging press 1. Two sets of guide rods 8 are disposed along the thickness direction of the moving plate 3. The two sets of guide rods 8 are distributed on both sides of the forging groove 101. A second spring 26 is sleeved on each set of guide rods 8. One end of the second spring 26 abuts against the end of the guide rod 8, and the other end abuts against the pushing plate 9 slidably disposed on the two sets of guide rods 8.

[0067] The movable plate 3 is also provided with a pusher, which includes an abutment plate 14 disposed on the movable plate 3. A third slide rod 1401 is disposed on the abutment plate 14 and is slidably disposed in the guide groove.

[0068] Specifically, the second spring 26 is in a compressed state, which pushes the push plate 9 to move towards the left (see reference). Figure 3 (As shown).

[0069] In the initial state, the first slide rod 401 is located at the end of the stroke of the slide groove 302, and the third slide rod 1401 is located at the connection between the fourth inclined groove 1302 and the transverse groove 1301. At this time, the baffle 27 blocks the third slide rod 1401. As the hydraulic forging 2 rises, the first slide rod 401 slides in the slide groove 302 until the moving rod 15 engages with the first locking groove 601, at which point the first slide rod 401 contacts the third inclined groove 301. Subsequently, as the hydraulic forging 2 continues to rise, the third inclined groove 301 cooperates with the first slide rod 401, which can drive the moving plate 3 to move the abutment plate 14 toward the push plate 9.

[0070] As the abutment plate 14 moves closer to the pusher plate 9, the third slide rod 1401 engages with the fourth inclined groove 1302, forcing the mounting plate 13 to lift the support plate 12. The support member 1201 then pushes the forged product gradually protruding from the forging groove 101 until the third slide rod 1401 engages with the stabilizing groove 1303. At this point, the support member 1201 pushes the forged product to be flush with the forging platform. The abutment plate 14 then contacts the pusher plate 9. As the moving plate 3 continues to move, the third slide rod 1401 slides along the stabilizing groove 1303. The forging plate 14 moves to keep the forged product flush with the forging platform. At the same time, the abutment plate 14 pushes the push plate 9 to move along the axial direction of the guide rod 8. During this process, the push plate 9 contacts the forged product and drives the forged product to slide along the forging platform until the first slide rod 401 moves to the end of the stroke of the third inclined groove 301. At this time, the forged product is completely separated from the forging groove 101, and the third slide rod 1401 moves to engage with the return groove 1304. At this time, under the influence of gravity, the lifting plate 12 falls back quickly so that the third slide rod 1401 contacts the transverse groove 1301.

[0071] When the billet is forged again, the hydraulic forging 2 descends. During this process, the moving plate 3 moves in the opposite direction first. At this time, the pushing plate 9 returns to the initial position with the cooperation of the second spring 26. At the same time, the third slide rod 1401 slides along the transverse groove 1301 and passes over the baffle 27 to return to the initial position.

[0072] When the moving plate 3 stops moving, the first slide rod 401 moves to engage with the slide groove 302, and the second slide rod 701 moves to engage with the deflection plate 22. The moving rod 15 descends under the influence of gravity and engages with the first inclined groove 602. As the hydraulic forging 2 continues to descend, the second slide rod 701 slides along the second inclined groove 2102 under the guidance of the deflection plate 22. During this process, the lifting plate 25 moves laterally relative to the moving rod 15, the first spring 18 is further compressed, and at the same time, the third spring 29 releases its elastic potential energy, driving the moving rod... 15 slides along the first inclined groove 602 until the second slide rod 701 moves to contact the vertical groove 2103. At this time, the moving rod 15 engages with the second locking groove 603. At this time, the lifting plate 25 separates from the moving rod 15. Subsequently, the hydraulic forging 2 continues to descend, causing the second slide rod 701 to engage with the horizontal groove 2104. Immediately afterwards, the first spring 18 releases its elastic potential energy, causing the second slide rod 701 to slide along the horizontal groove 2104 to the initial position. During this process, the moving rod 15 returns to the initial position synchronously under the influence of gravity.

[0073] Once forging is complete, repeat the above process to automatically eject the forged product again.

[0074] This invention also proposes an automatic ejection method for machine tool slide rail forgings, employing the automatic ejection structure for machine tool slide rail forgings as described above, comprising the following steps:

[0075] Step 1: After the hydraulic forging part 2 is forged, when it rises, the moving plate 3 remains stationary. After a period of time, the moving plate 3 slides along the axial direction of the guide rod 8.

[0076] Step 2: While the moving plate 3 remains stationary, the second slide rod 701 slides along the axial direction of the guide rod 8 under the guidance of the first fitting groove. During this process, the second slide rod 701, in cooperation with the first fitting groove, drives the moving rod 15 to rise, thereby blocking the water outlet 5 so that the water cooling pipe 11 can cool the forged finished product.

[0077] Step 3: During the subsequent movement of the moving plate 3, the third slide bar 1401 cooperates with the mounting plate 13 to drive the lifting plate 12 to rise, raise the forged product to be level with the forging platform and maintain the state unchanged. Then, the moving plate 3, which continues to move, can push the push plate 9 to slide along the axial direction of the guide rod 8, thereby separating the forged product from the forging groove 101.

[0078] Step 4: When the hydraulic forging part 2 rises to the highest point, the forged product is completely separated from the forging groove 101. At this time, the lifting plate 12 returns to its original position with the cooperation of the mounting plate 13.

[0079] Step 5: When the hydraulic forging 2 descends again, the moving rod 15 resets. Repeat steps one to four until the hydraulic forging 2 rises again, and the forging can be pushed out again.
