DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In a specific embodiment, Figure 1-Figure 3 As shown, the basic use process of the paper bowl mold is disclosed;

[0031] A base 1 and a support 2 fixedly mounted on the upper end of the base 1;

[0032] Two groups of support plates 3 are fixedly mounted on the upper end of the base 1, and two groups of guide rods 4 are fixedly mounted between the two groups of support plates 3. A movable plate 5 is slidably mounted on the outer side of the guide rod 4, and a hydraulic push rod 7 is fixedly mounted on the lower end of the movable plate 5. A mounting plate 8 is fixedly mounted on the lower end of the hydraulic push rod 7, and an extrusion piece 9 is fixedly mounted on the lower end of the mounting plate 8. A drive motor 10 is fixedly mounted on the outer side of the support plate 3, and an output shaft 11 is fixedly mounted on the output end of the drive motor 10, and the output shaft 11 is rotatably connected to the support plate 3, and the output shaft 11 is threadedly connected to the movable plate 5;

[0033] A driving rod 12 and a driven rod 13 are rotatably installed inside the base 1, and a sliding plate 14 is threadedly installed on the outer sides of the driving rod 12 and the driven rod 13. The sliding plate 14 is slidably connected to the base 1, and an extrusion plate 15 is slidably installed on the upper end of the sliding plate 14.

[0034] When using the high-precision bending mold for the production and processing of hardware, the mold needs to be placed in the required position, and the hardware to be bent is placed on the upper end of the support 2. At this time, the turntable on the outside of the driving rod 12 can be rotated, and the driving rod 12 will drive the driven rod 13 to rotate through the pulley structure arranged on the outside of the driving rod 12 and the driven rod 13. At this time, the two sets of sliding plates 14 and the extrusion plate 15 can be brought close to each other and clamp the two ends of the hardware. After that, the hydraulic push rod 7 can be used to push the mounting plate 8 and the extrusion part 9 downward and extrude the hardware through the extrusion part 9, so that the hardware is bent and shaped under the cooperation of the extrusion part 9 and the support 2, thereby completing the bending process of the bending mold.

[0035] In one specific embodiment, Figure 1-Figure 5 As shown, the process of high-precision bending of the bending die is disclosed;

[0036] A rotating rod 16 and a screw 17 are rotatably mounted inside the sliding plate 14, and a bevel gear set 18 is provided at one end where the rotating rod 16 and the screw 17 are close to each other, and the screw 17 is threadedly connected to the extrusion plate 15;

[0037] A motion rod 20 is rotatably mounted inside the sliding plate 14, and a second bevel gear set 21 is provided on one end of the motion rod 20 close to the sliding plate 14 and on the outside of the rotating rod 16. An adjustment rod 19 is rotatably mounted inside the support member 2, and the adjustment rod 19 is slidably connected to the motion rod 20.

[0038] Two sets of sliding plates 14 and extrusion plates 15 are symmetrically arranged about the vertical center axis of the support member 2 , and three sets of bevel gear sets 18 are arranged inside the sliding plate 14 .

[0039] When the high-precision bending mold for the production and processing of hardware is used, the two sets of sliding plates 14 are moved closer to each other by rotating the driving rod 12 and the driven rod 13. After the hardware is located at the upper end of the sliding plate 14, the turntable on the outside of the rotating rod 16 can be rotated. At this time, the rotating rod 16 will rotate and drive the screw 17 to rotate through the bevel gear set 18, and the rotation of the screw 17 will cause the extrusion plate 15 to slide downward and clamp the hardware. In this process, the rotating rod 16 will drive the moving rod 20 and the adjusting rod 19 to rotate through the bevel gear set 21, and the adjusting rod 19 will drive another set of moving rods 20 to rotate inside the other set of sliding plates 14, thereby causing the extrusion plate 15 at the upper end of the group of sliding plates 14 to move downward, completing the limiting process of the two ends of the hardware. By limiting the up and down and left and right ends of the hardware, it can be avoided that one end of the hardware is tilted during the bending process, thereby ensuring the accuracy of the hardware bending process.

[0040] Based on the above embodiments, Figure 1-Figure 7 As shown, the bending process of the bending die is disclosed;

[0041] A fixing plate 6 is fixedly mounted on the upper end of the base 1, and a connecting rod 23 is rotatably mounted inside the fixing plate 6. A ratchet 24 is fixedly mounted on the end of the connecting rod 23 away from the fixing plate 6. A mounting cylinder 25 is rotatably mounted on the outer side of the connecting rod 23, and the mounting cylinder 25 is located on the outer side of the ratchet 24.

[0042] A gear rod 29 is fixedly mounted on one end of the mounting cylinder 25 away from the connecting rod 23, and the gear rod 29 is located at the lower end of the mounting plate 8. A gear plate 22 is fixedly mounted on the lower end of the mounting plate 8, and the gear plate 22 is meshed with the gear rod 29.

[0043] A fixed shaft 26 is fixedly installed inside the mounting tube 25 , and a torsion spring 27 is sleeved on the outside of the fixed shaft 26 , and a ratchet 28 is rotatably installed on the outside of the fixed shaft 26 . The ratchet 28 is located on the outside of the torsion spring 27 and is meshed with the ratchet 24 .

[0044] When using the high-precision bending die for hardware production and processing, the driving motor 10 drives the output shaft 11 to rotate and causes the movable plate 5 to slide on the outside of the guide rod 4. During the movement of the movable plate 5, the hydraulic push rod 7 and the mounting plate 8 are driven to move, thereby changing the position of the mounting plate 8 and the extrusion piece 9.

[0045] When the hydraulic push rod 7 pushes the mounting plate 8 and the extrusion member 9 to move downward, the extrusion member 9 will cooperate with the support member 2 to bend the hardware, and the downward movement of the mounting plate 8 will drive the toothed plate 22 to move downward synchronously. During the downward movement of the toothed plate 22, it will mesh with the toothed rod 29 and drive the toothed rod 29 to rotate. When the toothed rod 29 rotates, the ratchet 24 will remain in meshing state with the ratchet teeth 28, and the torsion spring 27 is in an expanded state, so that the connecting rod 23 follows the rotation of the toothed rod 29. The two sets of connecting rods 23 are provided with a pulley structure on the outer side of the driving rod 12 and the driven rod 13, which will automatically drive the driving rod 12 and the driven rod 13 to rotate. At this time, the driving rod 12 and the driven rod 13 will make the two sets of sliding plates 14 approach each other, shorten the distance between the two sets of sliding plates 14, and ensure the limit position at both ends of the hardware after the hardware is bent;

[0046] And in the process of the mounting plate 8 driving the tooth plate 22 to move upward, the tooth plate 22 will still be in meshing state with the tooth rod 29. At this time, the tooth rod 29 will rotate in the opposite direction, and the ratchet 28 will be in a separated state from the ratchet wheel 24. The torsion spring 27 will shrink to prevent the rotation of the driving rod 12 and the driven rod 13, ensuring that the sliding plate 14 and the extrusion plate 15 continue to limit the two ends of the hardware, so that there is no need to continuously rotate the driving rod 12 to limit the two ends of the hardware, ensuring the convenience of using the bending mold and increasing the overall practicality.

[0047] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
