[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1 - Figure 7 As shown, this embodiment provides a bending machine die with high precision, including a support platform 1, and further including:

[0030] A positioning frame 2, fixedly connected to the upper surface of the support platform 1. A connecting plate 10 is arranged inside the positioning frame 2, and a lower die 3 is fixedly connected to the upper surface of the connecting plate 10;

[0031] A first installation component, respectively arranged on both sides of the outer wall of the positioning frame 2 and used to fix the positioning frame 2 and the connecting plate 10;

[0032] A lifting plate 5, located above the support platform 1. Fixed frames 6 are symmetrically arranged on the front surface of the lifting plate 5. Mounting plates 7 are arranged inside both fixed frames 6. Fixed brackets 8 are fixedly connected to the front surfaces of both mounting plates 7. The upper die 9 is fixedly connected to the bottom of both fixed brackets 8;

[0033] A second installation component, arranged inside the mounting plate 7 and used to fix the mounting plate 7 and the fixed frame 6;

[0034] An adjusting component, arranged on the upper surface of the support platform 1 and used to adjust the height position of the upper die 9.

[0035] The above working principle: When the material needs to be bent, just place the material on the upper surface of the lower die 3 first. At this time, the adjustment component starts to operate, and the adjustment component will drive the upper die 9 to move downward synchronously. When the upper die 9 completely coincides with the lower die 3, the material can be effectively bent through the cooperation between the upper die 9 and the lower die 3. When the specification of the lower die 3 needs to be replaced, just through the first installation component, the positioning frame 2 and the connecting plate 10 can be conveniently disassembled, so as to facilitate the staff to disassemble and replace the lower die 3. When the upper die 9 needs to be disassembled, just cancel the fixing effect between the mounting plate 7 and the fixed frame 6 through the second installation component, so that the staff can conveniently disassemble and replace the upper die 9 without using tools such as bolts, effectively improving the disassembly and assembly efficiency of the upper die 9 and the lower die 3, reducing the work burden of the staff, improving the bending efficiency of the material, and saving time and effort.

[0036] In order to conveniently and effectively fix and install the lower die 3, the first installation component includes fixing plates 4 respectively arranged on both sides of the outer wall of the positioning frame 2. Slide bars 19 are symmetrically arranged inside the fixing plates 4. Both ends of multiple slide bars 19 are fixedly connected to both sides of the inner wall of the fixing plates 4. A contact plate 20 is arranged inside the fixing plates 4. A guiding groove for the movement of the slide bars 19 is opened inside the contact plate 20. A return spring 21 is sleeved outside multiple slide bars 19. Multiple return springs 21 are all in contact between the contact plate 20 and the fixing plates 4. A pull plate is fixedly connected to the outside of the contact plate 20 through an outer plate 22. Plug rods 23 are fixedly connected to the opposite sides of both contact plates 20. Guiding grooves for the movement of the plug rods 23 are opened on the contact surfaces of the fixing plates 4 and the positioning frame 2. Guiding grooves for the movement of the plug rods 23 are opened on both sides of the outer wall of the connecting plate 10. When the lower die 3 needs to be fixed and installed, just pull the pull plate first. At this time, the pull plate will drive the outer plate 22 to move synchronously. The outer plate 22 then drives the contact plate 20 to move synchronously outside the slide bars 19. During the movement of the contact plate 20, the return spring 21 will be compressed. The contact plate 20 will also drive the plug rods 23 to move synchronously. At this time, insert the connecting plate 10 into the inside of the positioning frame 2, and then release the pull plate. At this time, the return spring 21 resets, driving the contact plate 20 to move synchronously. The contact plate 20 then drives the plug rods 23 to move synchronously. When the plug rods 23 are inserted into the guiding grooves on both sides of the outer wall of the connecting plate 10, the connecting plate 10 and the positioning frame 2 can be fixed, and at this time, the lower die 3 can be fixed and installed.

[0037] Considering that when bending the material, the upper die 9 also needs to be fixedly installed, the second installation component includes an inner plate 24 fixedly connected inside the mounting plate 7. On both sides of the outer wall of the inner plate 24, first telescopic rods 25 are fixedly connected. The telescopic ends of the plurality of first telescopic rods 25 are fixedly connected with fixing rods 26. The outer parts of the plurality of first telescopic rods 25 are sleeved with abutting springs 27. The plurality of abutting springs 27 are all abutted between the fixing rods 26 and the inner plate 24. Guide grooves for the fixing rods 26 to move are provided on both sides of the outer walls of the mounting plate 7 and the fixing frame 6. When it is necessary to fixedly install the upper die 9, only need to press the fixing rod 26 first. At this time, the fixing rod 26 will simultaneously squeeze the first telescopic rod 25 and the abutting spring 27. Then insert the mounting plate 7 into the fixing frame 6. At this time, the mounting plate 7 will drive the fixing rod 26 to move synchronously. When the mounting plate 7 drives the fixing rod 26 to move into the guide grooves on both sides of the outer wall of the fixing frame 6, the abutting spring 27 resets and drives the fixing rod 26 to move synchronously. When the fixing rod 26 is inserted into the guide grooves on both sides of the outer wall of the fixing frame 6, the mounting plate 7 and the fixing frame 6 can be fixed. At this time, the upper die 9 can be fixedly installed, and there is no need for workers to use tools such as bolts, effectively improving the disassembly and assembly efficiency of the upper die 9.

[0038] In order to facilitate the workers to disassemble the upper die 9, support blocks 11 are symmetrically arranged on the upper and lower surfaces of the fixing frame 6. Second telescopic rods 29 are fixedly connected to the outside of the plurality of support blocks 11. The telescopic ends of every two second telescopic rods 29 are fixedly connected with a pressing plate 30. The outer parts of the plurality of second telescopic rods 29 are sleeved with connecting springs 31. The plurality of connecting springs 31 are all abutted between the pressing plate 30 and the support blocks 11. On the opposite sides of every two pressing plates 30, a pressing rod 32 for squeezing the fixing rod 26 is fixedly connected. When it is necessary to disassemble the upper die 9, only need to press the pressing plate 30 first. At this time, the pressing plate 30 will drive the pressing rod 32 to move synchronously. When the pressing rod 32 squeezes the fixing rod 26 into the fixing frame 6, the mounting plate 7 can be pulled out from the fixing frame 6. At this time, the upper die 9 can be disassembled. During the movement of the pressing plate 30, the second telescopic rod 29 and the connecting spring 31 will also be squeezed synchronously. After the upper die 9 is disassembled, release the pressing plate 30. At this time, the connecting spring 31 resets and drives the pressing plate 30 to move synchronously in the reset direction. The pressing plate 30 then drives the pressing rod 32 to move synchronously in the reset direction.

[0039] In order to effectively extend the service life of the connecting spring 31 and the second telescopic rod 29, bellows dust covers 28 are sleeved on the outsides of multiple second telescopic rods 29. Both ends of the multiple bellows dust covers 28 are fixedly connected to the opposite sides of the support block 11 and the pressing plate 30 respectively. Through the setting of the bellows dust covers 28, the second telescopic rods 29 and the connecting spring 31 can be effectively protected from dust, so that the service life of the second telescopic rods 29 and the connecting spring 31 can be effectively extended, and at the same time, the normal use effect of the second telescopic rods 29 and the connecting spring 31 will not be affected at all.

[0040] In addition, in order to effectively bend the material, the adjusting assembly includes an adjusting plate 12 fixedly connected to the upper surface of the support table 1. A driving motor 13 is fixedly connected to the upper surface of the adjusting plate 12. The output shaft of the driving motor 13 is fixedly connected to a threaded rod 14 through a coupling. The bottom end of the threaded rod 14 is rotatably connected to the inner bottom end of the adjusting plate 12. A threaded block 15 is threadedly connected to the outside of the threaded rod 14. A guiding groove for the threaded block 15 to move is formed on the front end surface of the adjusting plate 12. The front end surface of the threaded block 15 is fixedly connected to the rear end surface of the lifting plate 5. When it is necessary to bend the material, just place the material on the upper surface of the lower die 3 first. At this time, the driving motor 13 starts to operate, and the driving motor 13 will drive the threaded rod 14 to rotate synchronously. The threaded block 15 will move synchronously on the outside of the threaded rod 14, driving the lifting plate 5 to move synchronously. The lifting plate 5 will then drive the upper die 9 to move synchronously. After the upper die 9 and the lower die 3 are completely closed, the material can be effectively bent through the cooperation between the upper die 9 and the lower die 3.

[0041] In order to effectively improve the stability of the upper die 9 during the moving process, side plates 16 are fixedly connected to both sides of the outer wall of the adjusting plate 12. Two guiding rods 17 are fixedly connected to the bottom of the two side plates 16. The bottom ends of the multiple guiding rods 17 are fixedly connected to the upper surface of the support table 1. Guiding blocks 18 are symmetrically arranged on the rear end surface of the lifting plate 5. Guiding grooves for the guiding rods 17 to move are formed in the interiors of the two guiding blocks 18. During the movement of the lifting plate 5, the guiding blocks 18 will also move synchronously on the outside of the guiding rods 17. At this time, the stability of the lifting plate 5 during the moving process can be effectively improved through the cooperation between the guiding blocks 18 and the guiding rods 17, so that the stability of the upper die 9 during the moving process can be effectively improved.
