Description

Technical Field

[0001] This invention relates to the field of press technology, specifically a press for the production of zinc-magnesium alloys. Background Technology

[0002] Zinc-magnesium alloy is a high-quality alloy material with zinc and magnesium as the main alloying elements. This alloy has the advantage of being lightweight and is widely used in various fields. When processing zinc-magnesium alloy, it is often necessary to make holes in the zinc-magnesium alloy. This is usually done by a press. The press drives the punch to move and complete the punching work of zinc-magnesium alloy. The punches on the press are fixedly mounted on the upper die base and are moved by the upper die base. When punching holes of different shapes or sizes, different punches need to be changed. Each time a punch needs to be changed, the punch needs to be installed and removed, which is very inconvenient. Summary of the Invention

An interlocking mechanism is installed on the punch changing assembly. The punch is locked by moving the assembly through the manipulation assembly.

[0005] Preferably, the upper die holder is provided with a stabilizing component, which positions the punch replacement component to ensure the accuracy of its rotation.

[0006] Preferably, the stabilizing component is a movable support rod, and a stabilizing ball block is fixedly installed at the lower end of the movable support rod. The stabilizing ball block is positioned by cooperating with the punch replacement component.

[0007] Preferably, the punch replacement assembly is a replacement turntable, on which a replacement carrier plate is fixedly arranged around the circumference, and the punch is mounted on the replacement carrier plate.

[0008] Preferably, the operating component includes: a movable strip, which is movably mounted on the upper mold base; An operating carrier bar is movably mounted on a movable plate.

[0009] Preferably, the movable strip is locked in conjunction with the replacement turntable.

[0010] Preferably, the operating bar cooperates with the changing turntable to drive the changing turntable to rotate.

[0011] Preferably, the operating bar is also equipped with a supporting movable bar, which can lock the movable bar plate and the operating bar.

[0012] Preferably, the interlocking mechanism includes a connecting link, which is movably mounted on the changing turntable and connected to the movable strip plate; A fixed pressure plate is movably mounted on a replacement carrier plate to press down and lock the punch. A fixed insertion post is also movably mounted on the replacement carrier plate to insert and lock the punch.

[0013] Preferably, both the fixed pressure plate and the fixed insertion post are movably connected to the connecting ring, and the connecting ring drives both of them to move.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. A changeover turntable is movably installed on the upper die base, and multiple different punches are installed on the changeover turntable. When punching zinc-magnesium alloy, when it is necessary to change the punch, simply rotate the changeover turntable to change the punch. It is very convenient and quick, and no operator is required to install or remove the punch.

[0015] 2. When changing the punch, lift the operating bar upwards to move the movable plate upwards, which unlocks the changing turntable. Then, push the operating bar to rotate the changing turntable under the action of the first and second push tops, so as to smoothly change the punch. The accuracy of the changing turntable rotation is ensured by the action of the stabilizing ball block, making the operation very convenient.

[0016] 3. In addition, when the movable plate moves upward, it can drive the connecting ring upward. As the connecting ring moves upward, all the punches on the replacement turntable can be unlocked, which facilitates the installation and removal of the punches. This makes it easier to replace and maintain the punches on the replacement turntable. When the connecting ring moves downward, it can lock all the punches to ensure their firmness and stability, thus ensuring their safety during the punching process. Attached Figure Description

[0029] This invention provides a technical solution: like Figure 1 and Figure 2 As shown, a press for producing zinc-magnesium alloy includes: a press body 1, on which an upper die holder 2 is mounted by screws.

[0030] like Figure 4As shown, an outwardly protruding strip 21 is integrally formed on the upper mold base 2. An assembly bearing hole 22 is provided on the outwardly protruding strip 21. A bearing upright 23 is also welded and fixed on the upper mold base 2 next to the outwardly protruding strip 21. A rod top block 24 is integrally formed on the upper end of the bearing upright 23. A mounting plate 25 is welded and fixed on the rod top block 24. A first support sleeve 26 is integrally formed on the lower side of the mounting plate 25, and a second support sleeve 27 is integrally formed on the upper side. The inner walls of the first support sleeve 26 and the second support sleeve 27 are smooth and burr-free. In addition, a bearing plate frame 28 is welded and fixed on the mounting plate 25. A movable mating hole 281 is provided on the bearing plate frame 28.

[0031] like Figure 3 and Figure 5 As shown, a punch 9 is installed on the punch replacement assembly, and the punch replacement assembly is installed on the upper die base 2 for replacing the punch 9. The upper end of the punch 9 is integrally formed with a mounting block 91. The mounting block 91 is provided with a fixing slot 92 and a fixing hole 93, and the punch 9 is fixed through the fixing slot 92 and the fixing hole 93.

[0032] like Figure 3 As shown, the control component is installed on the upper mold base 2, and the control component can lock the punch replacement component and drive the punch replacement component to rotate. The control component cooperates with the support rod 23 and moves up and down along the support rod 23.

[0033] like Figure 5 and Figure 9 As shown, the interlocking mechanism is installed on the punch replacement assembly. By manipulating the assembly to move it, the punch 9 is locked.

[0034] like Figure 3 and Figure 4 As shown, a stabilizing component is provided on the upper mold base 2. The stabilizing component positions the punch replacement component to ensure its rotation accuracy. The stabilizing component is a movable support rod 29. The lower end of the movable support rod 29 is integrally formed with a stabilizing ball block 291. The stabilizing ball block 291 is positioned by cooperating with the punch replacement component. In addition, the surface of the stabilizing ball block 291 is smooth and burr-free. The movable support rod 29 is inserted into the movable mating hole 281, and a stabilizing spring 292 is sleeved on the movable support rod 29. The stabilizing spring 292 is located on the lower side of the support plate frame 28, and the two ends of the stabilizing spring 292 are welded and fixed to the support plate frame 28 and the stabilizing ball block 291, respectively.

[0035] like Figure 3 , Figure 5 and Figure 6As shown, the punch replacement assembly is a replacement turntable 3. A replacement carrier plate 38 is integrally formed around the circumference of the replacement turntable 3. The punch 9 is mounted on the replacement carrier plate 38. A replacement support column 31 is welded and fixed to the replacement turntable 3. A mating protrusion ring 32 is integrally formed on the replacement support column 31, located below the outer protrusion 21. A bearing 33 is sleeved on the replacement support column 31 and installed in the assembly bearing hole 22. A support column 34 is also welded to the upper end of the replacement support column 31. A mating protrusion 35 is integrally formed around the circumference of the support column 34, with a smooth, burr-free surface. A drive carrier strip 36 is also integrally formed around the upper end of the support column 34, with a protruding mating strip 361 integrally formed on the drive carrier strip 36, also with a smooth, burr-free surface. Additionally, a mating top plate 37 is welded and fixed to the top of the support column 34. The top plate 37 has a stabilizing mating hole 371 on its circumference. When the stabilizing ball block 291 is used to stabilize and position the replacement turntable 3, part of the stabilizing ball block 291 is inserted into the stabilizing mating hole 371. A bearing protrusion 381 is welded and fixed on the replacement carrier plate 38. A moving guide hole 382 is opened on the bearing protrusion 381. Bearing rods 383 are also symmetrically welded on the replacement carrier plate 38. In addition, a mounting groove 39 is opened at the end of the replacement carrier plate 38 away from the replacement turntable 3. A through hole 391 is opened at the bottom of the mounting groove 39. The positioning of the punch 9 is achieved by the cooperation between the mounting groove 39 and the mounting support block 91. When the mounting support block 91 is inserted into the mounting groove 39, part of it protrudes outside the mounting groove 39. The punch 9 passes through the through hole 391 and protrudes from the lower side of the replacement carrier plate 38. The punch 9 installed on each replacement carrier plate 38 is different, but the mounting support block 91 on the punch 9 is the same.

[0036] like Figure 3 , Figure 7 and Figure 8 As shown, the control assembly includes: a movable strip 4, which is movably mounted on the upper mold base 2. One end of the movable strip 4 has a column mating hole 41, and a convex groove 42 is formed around the column mating hole 41. A connecting rod frame 43 is integrally formed symmetrically on the movable strip 4. A connecting plug 44 is integrally formed at the lower end of the connecting rod frame 43. The surface of the connecting plug 44 is smooth and burr-free. The other end of the movable strip 4 has an insertion through hole 45, in which a supporting column 23 is inserted. In addition, a support plate 46 is welded and fixed to one end of the movable strip 4 near the insertion through hole 45. A movable support rod 47 is welded and fixed to the support plate 46, and a limiting end block 48 is welded and fixed to the movable support rod 47.

[0037] The operating support bar 5 is movably mounted on the movable bar plate 4. The operating support bar 5 has a movable mating hole 51, and a movable support rod 47 is inserted into the movable mating hole 51.

[0038] The movable strip 4 is locked in conjunction with the replacement turntable 3. That is, the movable strip 4 is sleeved on the supporting column 34 through the column mating hole 41. When the movable strip 4 locks the replacement turntable 3, the mating protrusion 35 is inserted into the protrusion mating groove 42.

[0039] The operating carrier 5 cooperates with the changing turntable 3 to drive the changing turntable 3 to rotate. The upper side of the operating carrier 5 is integrally formed with a first push top 52. The surface of the first push top 52 is smooth and burr-free. The first push top 52 is integrally formed with a second push top 53. The surface of the second push top 53 is also smooth and burr-free. The first push top 52 and the second push top 53 are set at a 90-degree angle. When the operating carrier 5 pushes the changing turntable 3 to rotate, the first push top 52 first contacts the protruding mating strip 361 on the driving carrier 36 in front of it, pushing the changing turntable 3 to rotate initially. Then the second push top 53 contacts the protruding mating strip 361, pushing the changing turntable 3 to continue rotating until it rotates 90 degrees to complete the replacement of the punch 9.

[0040] The operating bar 5 is also equipped with a supporting movable bar 56, which can lock the movable bar 4 and the operating bar 5. A load-bearing rod 54 is welded and fixed on the operating bar 5, and a connecting spring 55 is sleeved on the load-bearing rod 54. The supporting movable bar 56 has a sleeve insertion hole 57, in which the load-bearing rod 54 is inserted. In addition, the two ends of the connecting spring 55 are welded and fixed to the supporting movable bar 56 and the operating bar 5, respectively. A supporting mating block 58 is integrally formed on the supporting movable bar 56. The surface of the supporting mating block 58 is smooth and burr-free. When the supporting mating block 58 is inserted into the first support sleeve 26 or the second support sleeve 27, it locks the movable bar 4 so that it cannot move up and down. When the supporting mating block 58 is inserted into the first support sleeve 26, it prevents the operating bar 5 from moving along the movable rod 47. At this time, the operating bar 5 is in contact with the limiting end block 48.

[0041] like Figure 3 , Figure 9 and Figure 10As shown, the interlocking mechanism includes a connecting ring 6, which is movably mounted on the replacement turntable 3 and connected to the movable strip plate 4. The connecting ring 6 is sleeved on the replacement support column 31 and is located on the upper side of the replacement turntable 3. A rotating annular groove 61 is provided on the connecting ring 6, and a connecting block 44 is inserted into the rotating annular groove 61. The connecting block 44 is in contact with the upper top surface and the inner bottom surface of the rotating annular groove 61. In addition, an extended support plate 62 is integrally formed on the circumference of the connecting ring 6. A support rod 63 is integrally formed on the end of the extended support plate 62 away from the connecting ring 6. An upper protruding block 64 is welded and fixed to the upper end of the support rod 63, and an extension connecting plate 65 is symmetrically integrally formed on the support rod 63. The extension connecting plate 65 is in contact with the replacement carrier plate 38, and a first connecting rod 66 is hinged to the upper protruding block 64.

[0042] The fixed pressure plate 7 is movably mounted on the replacement carrier plate 38 to press down and lock the punch 9. A support movable rod 71 is welded and fixed on the fixed pressure plate 7. The support movable rod 71 is inserted into the movable guide hole 382, ​​and a connecting mating strip 72 is welded and fixed to the end of the support movable rod 71 away from the fixed pressure plate 7. In addition, when the fixed pressure plate 7 locks the punch 9, it is inserted into the fixed slot 92 and contacts the inner wall of the fixed slot 92.

[0043] The fixed insert 8 is also movably mounted on the replacement carrier plate 38 to lock the punch 9. A connecting carrier plate 81 is welded and fixed on the fixed insert 8. A limiting bearing hole 82 is opened on the connecting carrier plate 81. A bearing rod 383 is inserted into the limiting bearing hole 82. A second connecting rod 83 is hinged on the connecting carrier plate 81. When the fixed insert 8 locks the punch 9, it is inserted into the fixed insert hole 93.

[0044] Both the fixed pressure plate 7 and the fixed insertion post 8 are movably connected to the connecting ring 6. The connecting ring 6 drives both of them to move. The lower end of the first connecting rod 66 is hinged to the connecting mating strip 72, and the lower end of the second connecting rod 83 is hinged to the extension connecting plate 65.

[0045] During punching, the upper die holder 2 moves the punch 9 downwards to punch the zinc-magnesium alloy. When the punch 9 needs to be replaced, the support movable bar 56 is pulled, causing the support mating block 58 to disengage from the first support sleeve 26. This unlocks the movable bar 4. Lifting the operating bar 5 upwards simultaneously moves the movable bar 4 upwards, separating the convex groove 42 from the mating convex 35. This unlocks the replacement turntable 3. Then, the support movable bar 56 is released, allowing it to move under the action of the connecting spring 55. This allows the support mating block 58 to insert into the second support sleeve 27, locking the movable bar 4. The support mating block 58 can then move along the second support sleeve 27. At this point, the first push top 52 and the second push top 53 are at the same height as the drive carrier 36. Then, the operating carrier 5 is pushed to move, causing the first push top 52 to contact the protruding mating strip 361 in front of it. Under the action of the first push top 52, the protruding mating strip 361 will be pushed to move, thereby driving the changing turntable 3 to rotate initially. Then, the second push top 53 will contact the protruding mating strip 361, and under the action of the second push top 53, the changing turntable 3 will continue to rotate until the changing turntable 3 rotates 90 degrees. At this point, the replacement of the punch 9 is completed. During the rotation of the changing turntable 3, under the action of the wall of the stabilizing mating hole 371, the stabilizing ball block 291 will disengage from the stabilizing mating hole. Hole 371 allows the changing turntable 3 to rotate smoothly. After the changing turntable 3 rotates 90 degrees, the corresponding stabilizing hole 371 reaches below the stabilizing ball block 291. Under the action of the stabilizing spring 292, the stabilizing ball block 291 will insert into the stabilizing hole 371 below it, thus positioning the changing turntable 3 and maintaining its stable rotation. After the punch 9 is replaced, the support movable bar 56 is pulled again to disengage the support mating block 58 from the second support sleeve 27, causing the movable bar plate 4 to move downwards. The convex groove 42 then engages with the mating convex bar 35 again to lock the changing turntable 3. Then, the operating bar 5 is pulled in the opposite direction to reset it, and the support mating block 58 is inserted back into the first support sleeve 26. In addition, when it is necessary to replace the punches 9 on the turntable 3 for inspection and maintenance, the movable plate 4 is moved upward. As the movable plate 4 moves upward, it will drive the connecting ring 6 to move upward. Under the action of the first connecting rod 66, the fixed pressure plate 7 will be moved, causing it to exit the fixed slot 92. At the same time, under the action of the second connecting rod 83, the fixed insertion post 8 will be moved, causing it to exit the fixed insertion hole 93. This unlocks all the punches 9 on the replacement turntable 3, making it easy to remove them quickly. When installing the punches 9, the mounting block 91 is inserted into the mounting groove 39 to position the punches 9. After the punches 9 are positioned, the movable plate 4 is released and moved downward, and the connecting ring 6 moves downward at the same time.This allows the fixing plate 7 to be inserted into the fixing slot 92 under the action of the first connecting rod 66, and the fixing pin 8 to be inserted into the fixing hole 93 under the action of the second connecting rod 83, achieving double locking of the punch 9. This ensures its stability and safety during the punching process, making both punch 9 replacement and punch 9 installation and removal very convenient and quick, and highly practical.
