Description

Technical Field

[0001] The present invention relates to the technical field of machine tool workpiece forging, and specifically to an automatic pushing-out structure for a forged finished product of a machine tool slide rail and a pushing-out method therefor. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal blank, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and dimensions. Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, the microstructural organization can be optimized. At the same time, due to the retention of the complete metal streamline, the mechanical properties of forgings are generally superior to those of castings made of the same material. For important parts with high loads and severe working conditions in related machinery, except for those with relatively simple shapes that can use rolled plates, profiles, or welded parts, forgings are mostly used.

[0003] Particularly, when forging and producing some precision forgings such as tool holders and machine tool slide rails, the surface of the forged finished product has many grooves. At this time, the surface of the forged finished product is still in a high-temperature and easily deformable state. When pushing out such a forged finished product, the forged finished product is likely to adhere to the forging groove. At this time, if forced to push out, it is easy to cause scratches on the surface of the finished product, resulting in damage to the finished product. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic pushing-out structure for a forged finished product of a machine tool slide rail and a pushing-out method therefor, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: An automatic pushing-out structure for a forged finished product of a machine tool slide rail, comprising: a forging press, on which a forging groove and a hydraulic forging part are provided; The forging press is further provided with a lifting component and a preprocessing component. During the ascending process of the hydraulic forging part, the preprocessing component is triggered and can first cool the forged finished product in the forging groove, so that the forged finished product cools and shrinks, thereby facilitating the subsequent lifting component to push out the forged finished product from the forging groove; The lifting component includes a driving structure, a lifting structure, and a pushing structure. The driving structure cooperates with the hydraulic forging part of the forging press. After the forged finished product is cooled, the hydraulic forging part drives the driving structure to act, thereby driving the lifting structure to push out the forged finished product placed in the forging press from the forging groove until the forged finished product is flush with the forging platform and then maintains the state unchanged. Then, it drives the pushing structure to push the forged finished product to slide along the forging platform, so that the forged finished product is completely separated from the forging groove.

[0006] Automatic ejection structure for the finished forging of the machine tool slide rail as described above: The pretreatment assembly includes a water-cooling pipe disposed within the forging press, a triggering structure mounted on the hydraulic forging, and a guiding member disposed on the forging press; The water outlet of the water-cooling pipe communicates with a water outlet member disposed on the forging press, and a blocking structure is provided on the water outlet member. The blocking structure includes a blocking plate slidably disposed on the water outlet member. A plugging rod is provided on a side of the blocking plate away from the water outlet member. A sleeve is slidably disposed on the plugging rod, and a moving rod is provided on the sleeve. The moving rod is connected to the guiding member. During the upward movement of the hydraulic forging, the triggering structure cooperates with the guiding member to block the water outlet member.

[0007] Automatic ejection structure for the finished forging of the machine tool slide rail as described above: The triggering structure includes a guide rail disposed on the hydraulic forging. A transverse movement plate is elastically slidably disposed on the guide rail. A second mounting member is provided on the transverse movement plate, and a second sliding rod is formed on the second mounting member. The second sliding rod cooperates with the guiding member to drive the blocking plate to slide relative to the water outlet member.

[0008] Automatic ejection structure for the finished forging of the machine tool slide rail as described above: The guiding member includes a guiding plate disposed on the forging press. A first fitting groove and a second fitting groove are formed on the guiding plate. The second sliding rod is slidably disposed in the first fitting groove, and 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 formed on the guiding plate, and a deflecting plate is elastically provided at the connection between the second inclined groove and the reset groove.

[0009] Automatic ejection structure for the finished forging of the machine tool slide rail as described above: The second fitting groove includes a first locking groove, a first inclined groove, and a second locking groove formed on the guiding plate.

[0010] Automatic ejection structure for the finished forging of the machine tool slide rail as described above: The driving structure includes a moving plate and a first mounting member. The moving plate is slidably disposed on the forging press. The first mounting member is disposed on the hydraulic forging, and a first sliding rod is provided on the first mounting member. The first sliding rod is slidably disposed in a composite groove formed on the moving plate. The composite groove includes a third inclined groove and a sliding groove.

[0011] Automatic ejection structure for finished forging of machine tool slide rail as described above: The lifting structure includes a lifting plate slidably arranged on the forging press. A series of supporting members adapted to the forging grooves are equidistantly distributed on the lifting plate. An installation plate is further arranged on the lifting plate. A guiding groove body is formed on the installation plate. The guiding groove body includes a transverse movement groove, a fourth inclined groove, a stabilizing groove and a falling-back groove formed on the installation plate. A baffle is elastically arranged at the connection of the fourth inclined groove and the transverse movement groove.

[0012] Automatic ejection structure for finished forging of machine tool slide rail as described above: The pushing structure includes guiding rods arranged on the forging press. There are two groups of guiding rods arranged along the thickness direction of the moving plate. The two groups of guiding rods are distributed on both sides of the forging groove. Second springs are sleeved on both groups of guiding rods. One end of each second spring abuts against the end of the guiding rod, and the other end abuts against a pushing plate slidably arranged on the two groups of guiding rods.

[0013] Automatic ejection structure for finished forging of machine tool slide rail as described above: A pushing member is further arranged on the moving plate. The pushing member includes an abutting plate arranged on the moving plate. A third sliding rod is arranged on the abutting plate. The third sliding rod is slidably arranged in the guiding groove body.

[0014] Correspondingly, an automatic ejection method for finished forging of machine tool slide rail is also proposed. Using the automatic ejection structure for finished forging of machine tool slide rail as described above, it includes the following steps: Step 1: After the hydraulic forging is completed and rising, the moving plate remains stationary first. After a period of time, the moving plate slides along the axial direction of the guiding rod. Step 2: During the process when the moving plate remains stationary, the second sliding rod slides along the axial direction of the guiding rod under the guidance of the first fitting groove. During this process, the second sliding rod drives the moving rod to rise under the cooperation of the first fitting groove, so as to block the water outlet member, so that the water-cooling pipe cools the forging finished product. Step 3: During the subsequent movement of the moving plate, the third sliding rod cooperates with the installation plate to drive the lifting plate to rise. After lifting the forging finished product to be flush with the forging platform and maintaining the state unchanged, then the continuously moving moving plate can push the pushing plate to slide along the axial direction of the guiding rod, so that the forging finished product is separated from the forging groove. Step 4: Until the hydraulic forging rises to the highest point, the forging finished product is completely separated from the forging groove. At this time, the lifting plate returns to its original position under the cooperation of the installation plate. Step 5: When the hydraulic forging descends again, the moving rod resets. Until the hydraulic forging rises again, repeat Steps 1 to 4 to eject the forging finished product again.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By setting up a pre-treatment component and a lifting component, during the upward movement of the hydraulic forging, first, the cooperation among the triggering structure, the blocking structure, and the guiding component in the pre-treatment component is utilized to enable the blocking plate to automatically block the water outlet, allowing cooling water to be introduced and retained in the water-cooling pipe. And during the blocking process, the third spring is compressed to store energy, which can enhance the sealing pressure between the blocking plate and the water outlet component, ensuring that the cooling water is retained in the water-cooling pipe without leakage, thereby improving the cooling efficiency. Moreover, when the cooling water uniformly cools the surface of the forging finished product, the cooling water can prompt the contact surface between the forging finished product and the forging groove to quickly shrink to form a gap, providing physical separation conditions for subsequent lifting, and avoiding excessive pushing resistance or scratching of the finished product surface caused by adhesion. And after the pre-treatment component cools the surface of the forging finished product, the continuously rising hydraulic forging can drive the lifting component to act. During this process, the cooperation among the driving structure, the lifting structure, and the pushing structure can first lift the forging finished product to be flush with the forging platform. After the lifting is completed, the pushing structure is used to horizontally push the forging finished product to ensure complete separation of the forging finished product from the forging groove. During the subsequent downward movement of the hydraulic forging, the cooperation among the first fitting groove, the second fitting groove, the triggering structure, and the blocking structure on the guiding component can release the water outlet component, enabling each component to return to its initial position for the subsequent ejection of the forging finished product again. The whole process requires no manual intervention. By utilizing the synergistic effect of mechanical linkage and physical cooling, the problems of easy adhesion and damage to the finished product during the traditional forging ejection process are solved, and the automatic ejection of precision forgings such as machine tool slide rails is realized.

[0029] The following will describe in detail various exemplary embodiments, features, and aspects of the present application with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified

[0030] As used herein, the term "exemplary" means "serving as an example, embodiment, or illustration". Any embodiment described as "exemplary" herein need not be construed as superior or better than other embodiments.

[0031] In addition, for a better illustration of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some of these specific details. In some instances, methods, means, and elements well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0032] Please refer to Figures 1-12 , in an embodiment of the present invention, an automatic pushing-out structure for a finished forging of a machine tool slide rail includes: A forging press 1, on which a forging groove 101 and a hydraulic forging part 2 are provided; Preferably, a forging blank is placed in the forging groove 101, and the hydraulic forging part 2 applies pressure to the blank in the forging groove 101 to cause plastic deformation, thereby obtaining a forging finished product with the required shape and size.

[0033] A lifting component and a pre-treatment component are further provided on the forging press 1. During the upward movement of the hydraulic forging part 2, the pre-treatment component is triggered and can first cool the forging finished product in the forging groove 101 so that the forging finished product cools and shrinks, thereby facilitating the subsequent lifting component to push the forging finished product out of the forging groove 101; The pre-treatment component includes a water-cooling pipe 11 arranged in the forging press 1, a triggering structure installed on the hydraulic forging part 2, and a guiding member arranged on the forging press 1; Specifically, please refer to Figure 1 , Figure 2 , the above-mentioned 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 cool the surface of the forging finished product. At this time, a certain gap will be generated between the contact surface of the forging finished product and the forging groove 101 due to cooling and shrinking, and this gap can facilitate the subsequent lifting component to lift the forging finished product out of the forging groove 101.

[0034] The water outlet of the water-cooling pipe 11 is communicated with a water outlet member 5 arranged on the forging press 1, and a blocking structure is arranged on the water outlet member 5. The blocking structure includes a blocking plate 19 slidably arranged on the water outlet member 5. A plugging rod 10 is arranged on the side of the blocking plate 19 away from the water outlet member 5. A socket cylinder 20 is slidably arranged on the plugging rod 10. A moving rod 15 is arranged on the socket cylinder 20. The moving rod 15 is connected to the guiding member. During the upward movement of the hydraulic forging part 2, the triggering structure cooperates with the guiding member to block the water outlet member 5; Specifically, please refer to Figure 6 , on the inner wall of the socket cylinder 20, a clamping block 2001 is formed. The clamping block 2001 is slidably arranged in a clamping groove 1001 opened on the insertion rod 10. With the cooperation of the clamping groove 1001, the clamping block 2001 and the guiding member, the socket cylinder 20 can only move along the axial direction of the insertion rod 10. Further, a third spring 29 is sleeved on the insertion rod 10. One end of the third spring 29 abuts against the socket cylinder 20, and the other end abuts against the sealing plate 19. Subsequently, with the cooperation between the triggering structure and the guiding member, during the process of driving the sealing plate 19 to contact the water-cooling pipe 11, the stored potential energy of the third spring 29 can be increased, 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 forging product.

[0035] The water-cooling pipe 11 is connected to a water pump arranged on the side (not shown in the figure). When the sealing plate 19 seals the water outlet member 5 under the cooperation of the triggering structure and the guiding member, the water pump is started synchronously to pump cooling water into the water-cooling pipe 11. At this time, the cooling water remains in the water-cooling pipe 11, and can cool the forging product to a certain extent for a short time (if the rapid cooling time is too long, it is easy to cause cracks in the forging product), so as to separate the forging product from the forging groove 101.

[0036] Specifically, please refer to Figures 1-8 , the triggering structure includes a guide rail 24 arranged on the hydraulic forging part 2. A transverse moving plate 16 is elastically slidably arranged on the guide rail 24. A second mounting member 7 is arranged on the transverse moving plate 16. A second sliding rod 701 is formed on the second mounting member 7. The second sliding rod 701 cooperates with the guiding member to drive the sealing plate 19 to slide relative to the water outlet member 5. Specifically, a sliding block 1601 is arranged on the transverse moving plate 16. The sliding block 1601 is slidably arranged in the guide rail 24. With the cooperation of the sliding block 1601 and the guide rail 24, the transverse moving plate 16 can only slide along the length direction of the guide rail 24. Further, a socket ring 1602 is arranged on the transverse moving plate 16. The socket ring 1602 is slidably connected to a fixed rod 17 arranged on the hydraulic forging part 2. A first spring 18 is sleeved on the fixed rod 17. One end of the first spring 18 abuts against the end of the fixed rod 17, and the other end abuts against the socket ring 1602.

[0037] Particularly, the first spring 18 is always in a compressed state, pushing the transverse moving plate 16 to have a tendency to move towards the left (refer to Figure 5 description).

[0038] Further, please refer to Figure 7, the guide member includes a guide plate 6 arranged on the forging machine 1, the guide plate 6 is provided with a first fitting groove and a second fitting groove, the second slide bar 701 is slidably arranged in the first fitting groove, the moving bar 15 is slidably arranged 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 arranged on the guide plate 6, and a deflection plate 22 is elastically arranged 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 the first elastic sheet 23, so that the deflection plate 22 can only be deflected counterclockwise in the direction of the second inclined groove 2102; 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; In the initial state, the second sliding rod 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 stroke end of the second locking groove 603 . At this time, the water outlet of the water cooling pipe 11 is connected.

[0039] In combination with the above, during the rising process of the hydraulic forging part 2, the second slide bar 701 first slides in the reset groove 2101. At this time, the lifting plate 25 fixed to the second slide bar 701 can contact the moving rod 15. During this process, the rising second slide bar 701, in cooperation with the lifting plate 25, synchronously drives the moving rod 15 to slide in the second locking groove 603, so that the blocking plate 19 gradually contacts the water outlet of the water-cooling pipe 11. After the second slide bar 701 rises a certain distance, the moving rod 15 contacts the first inclined groove 602, and the blocking plate 19 blocks the water outlet part 5. At this time, the water pump is turned on to pump cooling water into the water-cooling pipe 11. Water is used to cool the surface of the forged product. As the second sliding rod 701 continues to rise, the first inclined groove 602 forces the moving rod 15 to drive the sleeve 20 toward the sealing plate 19 to increase the compression of the third spring 29. During this process, the sealing plate 19 is always in a state of blocking the water outlet part 5, and the third spring 29 reacts on the sealing plate 19 to increase the extrusion pressure between the sealing plate 19 and the water outlet part 5, thereby continuously blocking the water outlet until the moving rod 15 contacts the first locking groove 601, the sealing plate 19 is separated from the water outlet, and the cooling water in the water-cooling pipe 11 is discharged from the water outlet part 5, and then the water pump is turned off.

[0040] The hydraulic forging part 2 subsequently continues to rise so that the second slide bar 701 moves over 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 part 2 cooperates with the lifting assembly to lift the forged product out of the forging groove 101.

[0041] Furthermore, please refer to Figures 1-5 and Figures 9-12 The lifting assembly includes a driving structure, a lifting structure, and a pushing structure. The driving structure cooperates with the hydraulic forging part 2 of the forging press 1. After the forging to be finished cools down, the hydraulic forging part 2 drives the driving structure to act, thereby driving the lifting structure to push the forging to be finished placed in the forging press 1 out of the forging groove 101 until the forging to be finished is flush with the forging platform and then maintains the state unchanged. Then, it drives the pushing structure to push the forging to be finished to slide along the forging platform so that the forging to be finished is completely separated from the forging groove 101.

[0042] The driving structure includes a moving plate 3 and a first mounting member 4. The moving plate 3 is slidably arranged on the forging press 1. The first mounting member 4 is arranged on the hydraulic forging part 2, and a first sliding rod 401 is arranged on the first mounting member 4. The first sliding rod 401 is slidably arranged in a composite groove opened on the moving plate 3. The composite groove includes a third inclined groove 301 and a sliding groove 302. Specifically, please refer to Figure 10 A convex block 303 is arranged on the above-mentioned moving plate 3. The convex block 303 is slidably arranged in a groove opened on the forging press 1. With the cooperation of the convex block 303 and the groove, the moving plate 3 can only slide along the length direction of the guide rail 24, so that the moving plate 3 can cooperate with the pushing structure to push the forging to be finished onto the forging platform later.

[0043] The lifting structure includes a lifting plate 12 slidably arranged on the forging press 1. A series of supporting members 1201 adapted to the forging groove 101 are equidistantly distributed on the lifting plate 12. An installation plate 13 is further arranged on the lifting plate 12. A guiding groove body is opened on the installation plate 13. The guiding groove body includes a transverse movement groove 1301, a fourth inclined groove 1302, a stable groove 1303, and a falling-back groove 1304 opened on the installation plate 13. A baffle 27 is elastically arranged at the connection of the fourth inclined groove 1302 and the transverse movement 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 installation plate 13 through a second elastic piece 28 so that the baffle 27 can only deflect clockwise towards the fourth inclined groove 1302. The pushing structure includes a guiding rod 8 arranged on the forging press 1. Two groups of guiding rods 8 are arranged along the thickness direction of the moving plate 3. The two groups of guiding rods 8 are distributed on both sides of the forging groove 101. A second spring 26 is sleeved on each of the two groups of guiding rods 8. One end of the second spring 26 abuts against the end of the guiding rod 8, and the other end abuts against a pushing plate 9 slidably arranged on the two groups of guiding rods 8. The moving plate 3 is also provided with a pushing member, and the pushing member includes an abutting plate 14 provided on the moving plate 3, and a third sliding rod 1401 is provided on the abutting plate 14, and the third sliding rod 1401 is slidably provided in the guide groove body; In particular, the second spring 26 is in a compressed state, pushing the push plate 9 to move toward the left side (refer to Figure 3 as shown).

[0044] In combination with the above, in the initial state, the first slide bar 401 is located at the stroke end of the slide groove 302, and the third slide bar 1401 is located at the connection between the fourth inclined groove 1302 and the transverse groove 1301. At this time, the baffle plate 27 blocks the third slide bar 1401. With the rise of the hydraulic forging 2, the first slide bar 401 slides in the slide groove 302 until the moving rod 15 is combined with the first locking groove 601, and the first slide bar 401 contacts the third inclined groove 301. Subsequently, with the continued rise of the hydraulic forging 2, the third inclined groove 301 cooperates with the first slide bar 401, which can drive the moving plate 3 to drive the abutting plate 14 to approach the pushing plate 9; In the process of the abutment plate 14 approaching the pushing plate 9, the third slide bar 1401 cooperates with the fourth inclined groove 1302 to force the mounting plate 13 to drive the lifting plate 12 to rise, and then the supporting member 1201 can push the forged product to gradually protrude from the forging groove 101, until the third slide bar 1401 is combined with the stabilizing groove 1303, and the supporting member 1201 pushes the forged product to be flush with the forging platform. At this time, the abutment plate 14 contacts the pushing plate 9, and the third slide bar 1401 slides along the stabilizing groove 1303 during the subsequent movement of the moving plate 3. Move so that the forged product is always 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 bar 401 moves to the end of the stroke of the third inclined groove 301, and the forged product is completely separated from the forging groove 101. The third slide bar 1401 moves to combine with the return groove 1304. At this time, under the influence of gravity, the lifting plate 12 falls back quickly to make the third slide bar 1401 contact with the transverse groove 1301.

[0045] When the next billet forging is performed, the hydraulic forging part 2 descends. During this process, the moving plate 3 first moves in the reverse direction. 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 bar 1401 slides along the transverse groove 1301 and passes over the baffle 27 to return to the initial position. When the moving plate 3 stops moving, the first slide bar 401 moves to be combined with the slide groove 302, the second slide bar 701 moves to be combined with the deflection plate 22, and the moving rod 15 is affected by gravity and falls to be combined with the first inclined groove 602. As the hydraulic forging 2 continues to fall, the second slide bar 701 slides along the second inclined groove 2102 under the guidance of the deflection plate 22. In this process, the lifting plate 25 moves horizontally relative to the moving rod 15, the first spring 18 is further compressed, and at the same time, the third spring 29 releases elastic potential energy to drive the moving rod 15 slides along the first inclined groove 602 until the second slide bar 701 moves to contact with the vertical groove 2103, and the moving rod 15 is combined with the second locking groove 603. At this time, the lifting plate 25 is separated from the moving rod 15, and the subsequent hydraulic forging part 2 continues to descend, so that the second slide bar 701 is combined with the horizontal groove 2104, and then the first spring 18 releases the elastic potential energy, so that the second slide bar 701 slides along the horizontal groove 2104 to the initial position, and in this process, the moving rod 15 returns to the initial position synchronously under the influence of gravity.

[0046] After forging is completed, the above process is repeated, and the forged product can be automatically pushed out again.

[0047] The present invention also proposes a method for automatically ejecting a machine tool slide rail forging product, which adopts the automatic ejection structure of the machine tool slide rail forging product as described above, and comprises the following steps: Step 1: After the hydraulic forging part 2 is forged, the moving plate 3 is kept still when it rises. After a period of time, the moving plate 3 slides along the axial direction of the guide rod 8; Step 2: While the moving plate 3 remains stationary, the second slide bar 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 bar 701 drives the moving rod 15 to rise under the cooperation of the first fitting groove, thereby blocking the water outlet part 5 so that the water cooling pipe 11 can cool the forged product; 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, lift the forged product to be flush with the forging platform and maintain the state unchanged, and then the moving plate 3 that continues to move can push the push plate 9 to slide along the axial direction of the guide rod 8, so that the forged product is separated from the forging groove 101; Step 4: When the hydraulic forging part 2 rises to the highest point, the forged product is completely separated from the forging groove 101, and the lifting plate 12 is restored to its original position with the cooperation of the mounting plate 13; Step 5: When the hydraulic forging part 2 descends again, the moving rod 15 is reset, and when the hydraulic forging part 2 rises again, steps 1 to 4 are repeated to push out the forged product again.
