Description

Technical Field

[0001] The utility model belongs to the technical field of centrifugal roller end cover manufacturing, in particular to a centrifugal roller end cover turning device. Background Art

[0002] Centrifugal rollers utilize centrifugal force to roll metal. During the centrifugal rolling process, a metal billet is placed inside or next to the rotating rollers. As the rollers rotate at high speeds, the centrifugal force stretches the metal into the desired shape and size. Centrifugal rollers are typically used to produce long, circular cross-section products such as pipes, bars, and wire.

[0003] During the production of centrifugal rollers, end caps serve to block molten iron during the centrifugal process. During the manufacturing process, the end caps are first struck with the small end facing upwards, then demolded. After demolding, the end caps are flipped so that the large end faces upwards for assembly with the cold mold. They are then flipped again with the small end facing upwards during the strike. Several flips are required during the manufacturing process. Currently, the end caps are flipped by inserting a lifting handle into the end cap box, hoisting the handle with a wire rope, and pressing the end cap to flip it. If the lifting handle is not properly inserted or the wire rope is not properly positioned, the end cap can fall off during the flipping process, causing injuries and other safety accidents.

In addition, the utility model also includes a flipping mechanism 6. When the clamping mechanism clamps the end cover and lifts the end cover to a certain height position, the end cover can be easily flipped through the provided flipping mechanism 6.

[0032] The clamping mechanism of the utility model can be referred to in the specific setting Figure 1 and Figure 2 ,according to Figure 1 and Figure 2 It can be seen that the clamping mechanism includes two cross-shaped clamping rods 1, which are arranged obliquely in the vertical direction, and the bottom end of each clamping rod 1 is hinged with a gripper 2 for clamping the end cover, and a clamping groove 21 is provided on the opposite side of the two grippers 2; continue to refer to Figure 1 and Figure 2 In order to facilitate the rotation of the two clamping rods 1, the top of each clamping rod 1 is connected to a chain body 3, and the two chain bodies 3 are connected to the same lifting ring 4.

[0033] The clamping groove 21 is specifically set with reference to Figure 1 It can be seen that the inner side wall of the clamping groove 21 is arranged obliquely, and the depth of the upper part of the clamping groove 21 is deeper than the depth of the lower part of the clamping groove 21, so that the large end and the small end of the end cover can be better clamped respectively.

[0034] The clamping rod 1 in the utility model can be further referred to when setting it specifically. Figure 1 and Figure 2 ,according to Figure 1 and Figure 2 It can be seen that each clamping rod 1 includes a rotating portion 11 arranged obliquely in a vertical plane and a vertically arranged clamping portion 12 located below the rotating portion 11 and fixedly connected to the bottom end of the rotating portion 11. A first rotating shaft 13 is provided through the center position of the rotating portion 11 of the two clamping rods 1. Therefore, the two clamping rods 1 are connected together by the first rotating shaft 13 and can rotate around the first rotating shaft 13, and the chain body 3 is connected to the top of the rotating portion 11; continue to refer to Figure 1 and Figure 2 The bottom of each clamping part 12 is connected to a second rotating shaft 15 through a bearing 14. Specifically, the outer ring of the bearing 14 is fixedly connected to the bottom of the clamping part 12, and the second rotating shaft 15 passes through the inner ring of the bearing 14 and is fixedly connected to the inner ring of the bearing 14. At the same time, the second rotating shaft 15 close to the flipping mechanism 6 extends away from the end of the corresponding gripper 2 to the outside of the corresponding bearing 14 and is provided with a slot 16 with a square cross-section.

[0035] The guide mechanism 5 of the present invention can be further referred to in the specific setting. Figure 2 ,according to Figure 2 It can be seen that the guide mechanism 5 includes a guide rail 51 vertically arranged at a position corresponding to the first rotating shaft 13 in a vertical plane, and a vertical guide groove 53 is provided on the side of the guide rail 51 facing the first rotating shaft 13, and a guide block that can slide up and down is provided in the guide groove 53, and the guide block is fixedly connected to the first rotating shaft 13.

[0036] The turning mechanism 6 in the present invention can be referred to in the specific setting Figure 1 and Figure 3 ,according to Figure 1 and Figure 3It can be seen that the flipping mechanism 6 includes a slide rail 61 fixedly connected to the guide rail 51 and arranged horizontally, and a slide groove 62 is provided on the downward side of the slide rail 61 along its length direction. A slider 63 is slidably connected in the slide groove 62, and the slider 63 is fixedly connected to the stepper motor 65 through a connecting rod 64. The output shaft of the stepper motor 65 is fixedly sleeved with an insert block 66 that cooperates with the slot 16.

[0037] The working principle of the centrifugal roller end cover flipping device of this embodiment is as follows: before using the present invention, first loosen the lifting ring 4, so that the two clamping rods 1 are lowered and rotated in opposite directions at the same time, thereby driving the two grippers 2 to move in opposite directions until the clamping groove 21 of the gripper 2 is parallel to the end cover and the end cover is located between the two grippers 2; then lift the lifting ring 4 upward through the lifting mechanism, first drive the chain body 3 to straighten, and then drive the two clamping rods 1 to rotate toward each other, thereby driving the two grippers 2 to move toward each other until the end cover is clamped, and as the lifting ring 4 moves upward, the clamped end cover is driven to move upward.

[0038] When the slot 16 on the second rotating shaft 15 and the insert block 66 are at the same height, the connecting rod 64, the stepper motor 65 and the insert block 66 are driven to move toward the second rotating shaft 15 by moving the slider 63 until the insert block 66 is inserted into the slot 16. Then, the stepper motor 65 drives the insert block 66, the second rotating shaft 15, the gripper 2 and the end cover to rotate until the end cover is flipped over. Then, the slider 63 is moved in the opposite direction to separate the insert block 66 and the slot 16.

[0039] Then the lifting ring 4 is lowered through the lifting mechanism until the flipped end cover is returned to its original position. As the lifting ring 4 continues to move downward, the chain body 3 is no longer tight. At this time, the two clamping rods 1 rotate in opposite directions, thereby driving the two grippers 2 to move in opposite directions, thereby loosening the clamped end cover.

[0040] Example 2

[0041] Embodiment 2 is based on embodiment 1, and a driving mechanism for driving the slider 63 to move back and forth is set in the slide 62. The driving mechanism can adopt a hydraulic rod or an electric rod, one end of the hydraulic rod or the electric rod is connected to the inner wall of the slide 62, and the other end is connected to the slider 63.

[0042] The above-mentioned driving mechanism can also adopt a threaded rod rotatably arranged in the slide groove 62, which passes through the slider 63 and is threadedly connected to the slider 63; in order to facilitate the driving of the threaded rod, a forward and reverse motor is provided at one end of the slide rail 61 corresponding to the position of the threaded rod, and the output shaft of the forward and reverse motor extends into the slide groove 62 and is fixedly connected to one end of the threaded rod.

[0043] In the above embodiment, the utility model provides a centrifugal roller end cover flipping device, which can clamp the end cover through the provided gripper; the provided clamping rod can drive the gripper to move, thereby achieving the purpose of clamping the end cover or lowering the end cover; through the provided chain body and lifting ring, when the lifting ring is pulled upward, the chain body is straightened, driving the clamping rod to rotate, so that the two grippers move toward each other, firmly clamping the end cover; when the lifting ring is lowered downward, the chain body is no longer in a taut state, and the clamping rod rotates in the opposite direction, so that the two grippers move in opposite directions, loosening and lowering the firmly clamped end cover.
