Description

A strip turning device for a cold-rolled strip steel production line Technical Field

[0001] This utility model relates to the field of cold-rolled strip steel production technology, specifically a strip steel turning device for a cold-rolled strip steel production line. Background Technology

[0002] The strip turning device in a cold-rolled strip production line is a key piece of equipment in the cold-rolled strip production process. It is mainly used to turn the strip on the production line to meet subsequent processing or technological requirements. During the cold-rolled strip production process, after the strip has undergone previous processing steps, it needs to enter the turning device for rotation. The turning device uses a motor or hydraulic system to drive the turning machine body and rotating frame to rotate, turning the strip from a horizontal position to a vertical position (or vice versa), thus achieving the strip turning.

[0003] Some existing devices use fixed blocking frames to block the sides of the strip before flipping, thus reducing the chance of the strip easily rotating. However, the position and tilt angle of the existing blocking frames are not adjustable, which results in poor blocking effect when flipping smaller strips. The strip is prone to rolling inside the device, which not only affects the stability of the strip during flipping but also reduces the safety of the device during use. Summary of the Invention

[0006] The receiving frame has two rotating baffles on both sides of its inner cavity. The inner cavity of the receiving frame is provided with a bidirectional threaded rod. Both sides of the surface of the bidirectional threaded rod are threaded with sleeves. The top of the sleeves is rotatably connected to a support rod. A rotating mechanism is installed on the surface of the bidirectional threaded rod.

[0007] The auxiliary frames rotate at the bottom of the baffle plate. Torsion springs are fixedly connected to both sides of the surface of the auxiliary frames. The receiving frame has two positioning frames at both sides of the inner cavity. A connecting plate is fixedly connected to one side of the positioning frame. An adjustment mechanism is installed at the bottom of the positioning frame.

[0008] Preferably, the rotating mechanism includes a first bevel gear fixed to the surface of a bidirectional threaded rod, a second bevel gear meshing with one side of the first bevel gear, and a rotating rod fixedly connected to one side of the second bevel gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a rotating mechanism in conjunction with a bidirectional threaded rod and a sleeve to adjust the tilt angle of the baffle plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5. A strip turning device for a cold-rolled strip production line includes a power mechanism 1. A receiving frame 2 is installed inside the power mechanism 1. The receiving frame 2 is used to receive the strip. Under the action of the power mechanism 1, the receiving frame 2 can rotate, thereby turning the strip. Baffle plates 3 are rotatably connected to both sides of the inner cavity of the receiving frame 2. The baffle plates 3 can block the strip, preventing it from easily detaching from the inside of the receiving frame 2. A bidirectional threaded rod 4 is provided inside the receiving frame 2. Sleeves 5 are threaded to both sides of the surface of the bidirectional threaded rod 4. A support rod 6 is rotatably connected to the top of the sleeve 5. The other end of the support rod 6 is rotatably connected to the bottom of the baffle plate 3. Under this action, when the bidirectional threaded rod 4 rotates, the two... Each sleeve 5 moves simultaneously in opposite directions. During this movement, the sleeve 5, in conjunction with the support rod 6, causes the blocking plate 3 to rotate, thereby adjusting its angle and blocking the strip. The double-threaded rod 4 facilitates adjustment of the blocking plate 3's tilt angle, allowing the device to change its tilt angle according to the strip size, effectively improving its applicability. Both ends of the double-threaded rod 4 are fixedly connected to bearing seats 14, the other side of which is fixedly connected to the inner wall of the receiving frame 2. This allows the double-threaded rod 4 to be supported by the bearing seats 14, making its rotation more stable and preventing instability from affecting the connection with the sleeve 5. The sleeve 5 is threaded, and a guide block 13 is fixedly connected to the bottom of the sleeve 5. The surface of the guide block 13 is slidably connected to the inner wall of the receiving frame 2. Under this action, the sleeve 5 will not have a large positional displacement when moving, so that the position of the sleeve 5 can be more accurate when moving. A rotating mechanism 7 is installed on the surface of the double-threaded rod 4. Under the action of the rotating mechanism 7, it is convenient for the operator to rotate the double-threaded rod 4, making the rotation of the double-threaded rod 4 easier. Auxiliary frames 8 are rotatably connected to two places at the bottom of the blocking plate 3. Torsion springs 9 are fixedly connected to both sides of the surface of the auxiliary frame 8. The other end of the torsion spring 9 is fixedly connected to the inner wall of the blocking plate 3. Under this action, the torsion spring can be used to rotate the double-threaded rod 4. With the cooperation of spring 9, the auxiliary frame 8 can rotate. Two locking frames 10 are provided on both sides of the inner cavity of the receiving frame 2. A connecting plate 11 is fixedly connected to one side of the locking frame 10. An adjustment mechanism 12 is installed at the bottom of the locking frame 10. The adjustment mechanism 12 facilitates the adjustment of the positions of the locking frame 10 and the connecting plate 11. Under this action, when the blocking plate 3 is tilted, the auxiliary frame 8 can contact the surface of the locking frame 10 through the cooperation of the torsion spring 9, thus enabling the auxiliary frame 8 to support the blocking plate 3 when it is under force, thereby making the blocking plate 3 more stable. When it is necessary to adjust the blocking plate 3 into the interior of the receiving frame 2, the adjustment mechanism 12 can make the connecting plate 11 contact the surface of the auxiliary frame 8.This design ensures that the auxiliary frame 8 does not interfere with the normal rotation of the blocking plate 3 when it rotates downwards, thus facilitating the repositioning of the blocking plate 3. One side of the positioning frame 10 has an inclined structure design, and the positioning frame 10 works in conjunction with the connecting plate 11.

[0023] The rotating mechanism 7 includes a first bevel gear 71 fixed to the surface of the bidirectional threaded rod 4. A second bevel gear 72 meshes with one side of the first bevel gear 71. A rotating rod 73 is fixedly connected to one side of the second bevel gear 72. The other end of the rotating rod 73 passes through the outer side of the receiving frame 2 and is rotatably connected to the inner wall of its penetration point. Under this action, when the operator needs to rotate the bidirectional threaded rod 4, the cooperation between the rotating rod 73 and the second bevel gear 72 and the first bevel gear 71 makes it more convenient for the operator to rotate the bidirectional threaded rod 4, effectively improving the applicability of the device.

[0024] The adjustment mechanism 12 includes a positioning groove 121 formed in the inner cavity of the receiving frame 2. A positioning block 122 is slidably connected to the inner cavity of the positioning groove 121. The top of the positioning block 122 is fixedly connected to the bottom of the positioning frame 10. A movable frame 123 is fixedly connected to one side of the positioning frame 10. One side of the movable frame 123 is slidably connected to the surface of the receiving frame 2. Under this function, when the position of the positioning frame 10 needs to be adjusted, the movable frame 123 can be used to move the positioning block 122 inside the positioning groove 121, thereby making the positioning frame 10 more stable when moving. A magnet 15 is fixedly connected to the inner wall of the receiving frame 2. The movable frame 123 is made of iron. The movable frame 123 and the magnet 15 work together. Under this function, the positioning frame 10 can be limited by the cooperation of the magnet 15, preventing it from easily shifting its position when squeezed by the auxiliary frame 8, effectively improving the stability of the positioning frame 10 during use.

[0025] It is worth noting that the technical features such as the power mechanism 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, when the tilt angle of the baffle plate 3 needs to be adjusted, the operator rotates the rotating rod 73, which, through the second bevel gear 72 and the first bevel gear 71, drives the double-threaded rod 4 to rotate. This causes the support rod 6 to support the baffle plate 3 through the sleeve 5, thus rotating the baffle plate 3 and adjusting its angle until it is adapted to the size of the strip. This improves the blocking effect on the strip, reduces the likelihood of the strip shifting easily, and effectively improves the stability of the strip during flipping. While the baffle plate 3 rotates... The auxiliary frame 8 and the positioning frame 10 are brought into contact by the torsion spring 9. Under the action of the shape, the auxiliary frame 8 will support the blocking plate 3 through the positioning frame 10 when the blocking plate 3 is under force, so as to make it more stable. Then the strip steel is placed inside the receiving frame 2 and limited by the blocking plate 3. Then the power mechanism 1 is turned on to flip the strip steel through the receiving frame 2. After the flipping is completed, when the blocking plate 3 needs to be reset, the positioning frame 10 is moved by the movable frame 123 to no longer contact the auxiliary frame 8 until it contacts the connecting plate 11. Then the blocking plate 3 can be reset by the rotation mechanism 7.
