Abstract
Description
Technical Field
[0001] This utility model relates to the field of correction rollers, and more specifically, to a correction roller for rolling large annular parts. Background Technology
[0002] Annular part rolling is a processing technology that uses a die formed by rolling rollers and core rollers to continuously and locally plastically deform an annular blank. It belongs to the rotary forging method. During rolling, a guide roller is required. The guide roller automatically adjusts its angle through its unique design structure, which can automatically correct and prevent deviation.
[0003] Currently, most of the straightening rollers used for rolling large annular parts have the following problems:
[0004] I. Existing straightening rollers for rolling large annular parts mostly rely on the tilt angle of the rollers for straightening. The tilt angle of the rollers is mostly fixed, which limits their guiding and limiting functions. Large annular parts come in different sizes. If the large annular part is small, the tilting rollers on both sides cannot be used for limiting and guiding, making it inconvenient to adjust the tilt angle of the rollers.
[0005] Second, the existing large-scale ring-shaped rolling mill correction rollers are mostly placed aside when not in use, with the installed correction rollers exposed. When the equipment is moved, the exposed correction rollers are easily damaged by bumps and other incidents, making it inconvenient to protect the equipment.
[0006] Therefore, we have made improvements and proposed a correction roller for rolling large annular parts. Utility Model Content
[0007] The purpose of this utility model is to address the current problems of inconvenience in adjusting the tilt angle of the correction roller and inconvenience in protecting the equipment.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] Correcting rollers are used for rolling large annular parts to improve the above problems.
[0010] The application is as follows:
[0011] The system includes a base, a bidirectional threaded rod rotatably connected to the base, a turntable fixedly connected to the bidirectional threaded rod, a movable block threadedly connected to the bidirectional threaded rod, a fixed frame fixedly connected to the movable block, a push plate rotatably connected to the fixed frame, a connecting frame rotatably connected to the other end of the push plate, a correction roller rotatably connected to the connecting frame, a first fixed plate rotatably connected to the other end of the connecting frame, the first fixed plate fixedly connected to the base, a second fixed plate fixedly connected to the base, a support roller rotatably connected to the second fixed plate, a protective box provided on the base, a mounting box fixedly connected to the protective box, a first spring fixedly connected inside the mounting box, a pressure block fixedly connected to the other end of the first spring, a pull rod fixedly connected to the pressure block, a sliding rod fixedly connected inside the mounting box, a slider slidably connected to the upper limit of the sliding rod, and a second spring fixedly connected to the slider.
[0012] As a preferred technical solution of this application, the end of the bidirectional threaded rod is fixedly connected to the center of one side of the turntable, and the bottom surface of the moving block is in contact with the bottom surface inside the base.
[0013] As a preferred technical solution of this application, the movable blocks are symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the movable blocks correspond one-to-one with the push plate through the fixing frame.
[0014] As a preferred technical solution of this application, the side end face of the pressure block is in contact with the inner side of the mounting box, and the cross-section of the pull rod is "T" shaped.
[0015] As a preferred technical solution of this application, the other end of the second spring is fixedly connected to the mounting box, a locking rod is fixedly connected to the slider, a positioning plate is fixedly connected to the base, and the end face of the slider is inclined.
[0016] As a preferred technical solution of this application, the sliders are symmetrically distributed on the left and right sides of the slide bar, and the sliders correspond one-to-one with the locking rods through the second spring.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In the scheme of this application:
[0019] 1. Equipped with a bidirectional threaded rod; when adjusting the tilt angle of the straightening roller, the turntable can be rotated to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod can push the two moving blocks on both sides to move inward. At the same time, the moving blocks drive the fixed frame to move. The push plate on the fixed frame can push the connecting frame to rotate on the first fixed plate, which can adjust the tilt angle of the connecting frame to adapt to large ring parts of different sizes.
[0020] 2. Equipped with a protective box; when protection of the alignment rollers and idler rollers on the base is required, the pull rod on the mounting box can be pulled to move the pressure block. The pressure block can compress the first spring, while the slider is unobstructed. Under the push of the second spring, the slider slides back to its original position on the slide rod. The locking rod on the slider can be retracted into the mounting box. The protective box can be placed on the base to protect the alignment rollers and idler rollers. Releasing the pull rod will cause the pressure block to reset under the push of the first spring. The pressure block can press the slider, and the slider compresses the second spring. The locking rod on the slider can engage with the positioning plate on the base for fixed positioning. Attached Figure Description

The first fixed plate 9 is fixedly connected to the base 1. On the base 1, a second fixing plate 10 is fixedly connected to the base 1, and a roller 11 is rotatably connected to the second fixing plate 10. A protective box 12 is provided on the base 1, and an installation box 13 is fixedly connected to the protective box 12. A first spring 14 is fixedly connected inside the installation box 13, and a pressure block 15 is fixedly connected to the other end of the first spring 14. A pull rod 16 is fixedly connected to the pressure block 15. A sliding rod 17 is fixedly connected inside the installation box 13, and a slider 18 is slidably connected to the upper limit of the sliding rod 17. A second spring 19 is fixedly connected to the slider 18.
[0034] Example 2:
[0035] The solution in Example 1 will be further described below with reference to its specific working method.
[0036] like Figure 2 As shown, in a preferred embodiment, based on the above method, the end of the bidirectional threaded rod 2 is fixedly connected to the center of one side of the turntable 3, and the bottom surface of the moving block 4 is in contact with the bottom surface inside the base 1, which can ensure that the moving block 4 can move smoothly by being supported by the contact of the bottom surface inside the base 1 when it moves.
[0037] like Figure 2 As shown, in a preferred embodiment, based on the above method, the movable blocks 4 are symmetrically distributed on the left and right sides of the bidirectional threaded rod 2. The movable blocks 4 correspond one-to-one with the push plates 6 through the fixed frame 5, which can ensure that the push plates 6 on both sides can push the connecting frame 7 through the push plates 6 to adjust the angle.
[0038] like Figure 2 As shown, in a preferred embodiment, based on the above method, the side end face of the pressure block 15 is in contact with the inner side of the mounting box 13, and the cross-section of the pull rod 16 is "T" shaped, which can ensure that the pressure block 15 can move smoothly by contacting the inner side of the mounting box 13 when it moves up and down.
[0039] like Figure 4 As shown, in a preferred embodiment, based on the above method, the other end of the second spring 19 is fixedly connected to the mounting box 13, a locking rod 20 is fixedly connected to the slider 18, a positioning plate 21 is fixedly connected to the base 1, and the end face of the slider 18 is inclined, which can ensure that when the pressure block 15 is pressed down, it can be pressed and pushed through the inclined surface of the slider 18.
[0040] like Figure 4 As shown, in a preferred embodiment, based on the above method, the sliders 18 are symmetrically distributed on the left and right sides of the slider 17. The sliders 18 correspond one-to-one with the locking rods 20 through the second spring 19, which can ensure that the locking rods 20 on both sides can be locked in the positioning plate 21 to fix and limit the installation box 13 and the protective box 12.
[0041] Specifically, when using the correction roller for rolling this large annular component, it should be combined with: Figure 1-4 When adjusting the tilt angle of the straightening roller 8, the turntable 3 can be rotated to drive the bidirectional threaded rod 2 to rotate. The bidirectional threaded rod 2 can push the two moving blocks 4 on both sides to move inward. At the same time, the moving blocks 4 drive the fixed frame 5 to move. The push plate 6 on the fixed frame 5 can push the connecting frame 7 to rotate on the first fixed plate 9, so as to adjust the tilt angle of the connecting frame 7 to adapt to large ring parts of different sizes. The roller 11 on the second fixed plate 10 can cooperate with the straightening roller 8 to roll and guide the large ring parts.
[0042] When protection is needed for the alignment roller 8 and the support roller 11 on the base 1, the pull rod 16 on the mounting box 13 can be pulled to move the pressure block 15. The pressure block 15 can press the first spring 14, while the slider 18 is unobstructed. Under the push of the second spring 19, the slider 18 slides back on the slide rod 17. The locking rod 20 on the slider 18 can be retracted into the mounting box 13. The protective box 12 can be placed on the base 1 to protect the alignment roller 8 and the support roller 11. When the pull rod 16 is released, the pressure block 15 is reset under the push of the first spring 14. The pressure block 15 can press the slider 18, and the slider 18 presses against the second spring 19. The locking rod 20 on the slider 18 can engage with the positioning plate 21 on the base 1 for fixed positioning.
