Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 2 As shown in Embodiment 1, a novel conveying conduit 1 for a high-speed bar rolling production line includes: a conduit 1, an upper sleeve seat 2, and a lower sleeve seat 3; a fixing head 1-1 is fixedly installed on the conduit 1, the fixing head 1-1 is hexagonal, the hexagonal fixing head 1-1 has equidistant planes 1-2, and the space between adjacent planes 1-2 is an arc surface 1-3; the upper sleeve seat 2 can hold the top of the fixing head 1-1, and the lower sleeve seat 3 can support the bottom of the fixing head 1-1; the upper sleeve seat 2 is rotatably installed on the right end of the lower sleeve seat 3; the left end of the upper sleeve seat 2 has an upper insertion interface 4, and the left end of the lower sleeve seat 3 has a lower insertion interface 5; the upper insertion interface 4 corresponds to the lower insertion interface 5, and bolts 6 are inserted into the upper insertion interface 4 and the lower insertion interface 5.

[0022] When in use, rotate the upper sleeve seat 2 on the lower sleeve seat 3 so that the lower sleeve seat 3 can open, and place the fixing head 1-1 inside the lower sleeve seat 3 so that the lower sleeve seat 3 supports the bottom end of the fixing head 1-1.

[0023] Next, rotate the upper sleeve seat 2 so that it is fastened to the top of the fixing head 1-1. Then, pass the bolt 6 through the upper insertion interface 4 and the lower insertion interface 5 in sequence. Rotate the bolt 6 so that the upper insertion interface 4 and the lower insertion interface 5 can be relatively tightened, so that the upper sleeve seat 2 and the lower sleeve seat 3 can be locked together. Then, fix the fixing head 1-1 inside the upper sleeve seat 2 and the lower sleeve seat 3 so that the guide tube 1 is stably clamped and provides a conveying surface for high-speed bar rolling.

[0024] The upper sleeve seat 2 has an upper surface 2-1 at its inner top, and the lower sleeve seat 3 has a lower surface 3-1 at its inner bottom. Both the upper surface 2-1 and the lower surface 3-1 can contact the surface 1-2 of the fixing head 1-1. The inner walls of the upper sleeve seat 2 and the lower sleeve seat 3 are in contact with the arc surface 1-3.

[0025] When the fixing head 1-1 is fixed inside the upper sleeve seat 2 and the lower sleeve seat 3, the upper plane 2-1 and the lower plane 3-1 are in close contact with the plane 1-2, and the interior of the upper sleeve seat 2 and the lower sleeve seat 3 are in contact with the arc surface 1-3, so that the fixing head 1-1 can remain locked and prevent the fixing head 1-1 from rotating.

[0026] When it is necessary to change the conveying surface, loosen bolt 6 so that the upper sleeve seat 2 and the lower sleeve seat 3 can release the clamping force, so that the upper sleeve seat 2 and the lower sleeve seat 3 can rotate, and rotate the fixing head 1-1 so that the adjacent plane 1-2 contacts the upper plane 2-1 and the lower plane 3-1, so that the conveying surface can rotate.

[0027] After the fixed head 1-1 is rotated, the bolt 6 is rotated so that the upper insertion interface 4 and the lower insertion interface 5 can be relatively tightened, so that the upper sleeve seat 2 and the lower sleeve seat 3 can be locked together, and the fixed head 1-1 is fixedly installed inside the upper sleeve seat 2 and the lower sleeve seat 3, so that the guide tube 1 is stably clamped and provides a conveying surface for high-speed bar rolling.

[0028] like Figures 3 to 6 As shown, in Embodiment 2, the upper sleeve seat 2 has an upper cavity 2-2, and the lower sleeve seat 3 has a lower cavity 3-2. A first moving block 2-3 is slidably installed in the upper cavity 2-2, and a second moving block 3-3 is slidably installed in the lower cavity 3-2. An upper driving ring 2-4 is slidably installed inside the upper cavity 2-2, and a lower driving ring 3-4 is slidably installed inside the lower cavity 3-2.

[0029] In use, the first moving block 2-3 and the upper driving ring 2-4 slide in the upper cavity 2-2 respectively, so that the first moving block 2-3 can be in close contact with the plane 1-2, the second moving block 3-3 and the lower driving ring 3-4 slide in the lower cavity 3-2 respectively, so that the second moving block 3-3 can be in close contact with the plane 1-2, the plane 1-2 at the upper and lower ends of the fixed head 1-1 is tightly clamped by the upper and lower moving blocks, so that the fixed head 1-1 can be fixedly installed in the upper and lower sleeve seats 2 and 3, and the fixed head 1-1 can be kept in a locked state.

[0030] The first moving block 2-3 is fixedly installed with the first spring 2-5 at both ends, the top end of the first spring 2-5 is fixedly installed in the upper cavity 2-2, and the second moving block 3-3 is fixedly installed with the second spring 3-5 at both ends, the bottom end of the second spring 3-5 is fixedly installed in the lower cavity 3-2.

[0031] When the first spring 2-5 is not stressed, the first spring 2-5 is in a compressed state, so that the first moving block 2-3 can be accommodated in the upper cavity 2-2, when the first moving block 2-3 moves away from the upper cavity 2-2, the first spring 2-5 is stretched, so that the first moving block 2-3 can be in contact with the plane 1-2, when the second spring 3-5 is not stressed, the second spring 3-5 is in a compressed state, so that the second moving block 3-3 can be accommodated in the lower cavity 3-2, when the second moving block 3-3 moves away from the lower cavity 3-2, the second spring 3-5 is stretched, so that the second moving block 3-3 can be in contact with the plane 1-2.

[0032] The upper driving ring 2-4 penetrates the outer wall of the upper sleeve seat 2 at both ends, the lower driving ring 3-4 penetrates the outer wall of the lower sleeve seat 3 at both ends, the lower driving ring 3-4 is fixedly installed with the extension plate 3-8 at both ends, the extension plate 3-8 can cover the end of the upper driving ring 2-4, and the lower driving ring 3-4 is fixedly installed with the protrusion 3-9 at both inner ends.

[0033] When the upper sleeve base 2 rotates on the lower sleeve base 3, the upper driving ring 2-4 and the lower driving ring 3-4 can be driven to rotate relatively, so that the end of the upper driving ring 2-4 is in contact with the extension plate 3-8, and the upper driving ring 2-4 and the lower driving ring 3-4 slide in the upper cavity 2-2 and the lower cavity 3-2 respectively. When the lower driving ring 3-4 is in the initial state, the protrusion 3-9 can be in contact with the plane 1-2 on both sides of the lower end of the fixed head 1-1. When the fixed head 1-1 is sleeved in the lower sleeve base 3, the protrusion 3-9 can limit the bottom end of the fixed head 1-1. When the fixed head 1-1 is installed in the lower sleeve base 3, the two ends of the upper driving ring 2-4 are in contact with the two sides of the fixed head 1-1, so that the fixed head 1-1 can be stably installed in the lower sleeve base 3, preventing the fixed head 1-1 from being deflected. When the upper sleeve base 2 is buckled, misalignment occurs, and the bolt 6 is sequentially threaded through the upper contact head and the lower contact head, and the bolt 6 is rotated. The upper driving ring 2-4 and the lower driving ring 3-4 can be in close contact.

[0034] The first mobile block 2-3 and the corresponding side of the upper driving ring 2-4 are both provided with a first tooth groove 2-6. The first gear 2-7 is rotatably installed in the upper cavity 2-2. The two first tooth grooves 2-6 are respectively engaged in the two ends of the first gear 2-7.

[0035] When the upper driving ring 2-4 slides in the upper cavity 2-2, the first tooth groove 2-6 on one side is displaced, so that the first gear 2-7 is rotated, and the first tooth groove 2-6 on the other side is displaced in the opposite direction of the upper driving ring 2-4. When the upper sleeve base 2 is in close contact with the lower sleeve base 3, the upper driving ring 2-4 slides into the upper cavity 2-2, so that the first mobile block 2-3 is in close contact with the plane 1-2.

[0036] The second mobile block 3-3 and the corresponding side of the lower driving ring 3-4 are both provided with a second tooth groove 3-6. The second gear 3-7 is rotatably installed in the lower cavity 3-2. The two second tooth grooves 3-6 are respectively engaged in the two ends of the second gear 3-7.

[0037] When the lower driving ring 3-4 slides in the lower cavity 3-2, the second tooth groove 3-6 on one side is displaced, so that the second gear 3-7 is rotated, and the second tooth groove 3-6 on the other side is displaced in the opposite direction of the lower driving ring 3-4. When the upper sleeve base 2 is in close contact with the lower sleeve base 3, the lower driving ring 3-4 slides into the lower cavity 3-2, so that the second mobile block 3-3 is in close contact with the plane 1-2, and cooperates with the first mobile block 2-3 to stably install the fixed head 1-1 in the upper sleeve base 2 and the lower sleeve base 3;

[0038] When the plane 1-2 needs to be replaced, the bolt 6 is loosened, the upper sleeve seat 2 and the lower sleeve seat 3 are rotated, the end of the upper driving ring 2-4 and the lower driving ring 3-4 is loosened, the first moving block 2-3 and the second moving block 3-3 are respectively subjected to the force of the first spring 2-5 and the second spring 3-5, the first moving block 2-3 and the second moving block 3-3 are separated from the plane 1-2, and the fixed head 1-1 is rotated, so that the plane 1-2 of the fixed head 1-1 is switched.

[0039] Compared with the first embodiment, the second embodiment has the upper sleeve seat 2 and the lower sleeve seat 3, which do not need to be opened when the plane 1-2 is replaced, so that the upper sleeve seat 2 and the lower sleeve seat 3 form a complete closed loop, so that the fixed head 1-1 cannot be separated from the upper sleeve seat 2 and the lower sleeve seat 3 when the fixed head 1-1 is rotated, and the plane 1-2 can be replaced stably and conveniently.

[0040] The technical scope of the utility model is not limited to the above-mentioned content in the specification, and those skilled in the art can deform and modify the above-mentioned embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the scope of the utility model.
