Description

Technical Field

[0001] This utility model relates to the field of steel strip processing technology, and more specifically, to a steel strip rolling mechanism. Background Technology

[0002] Steel strip is a type of metal material, mainly processed through rolling, drawing and other processes to meet the needs of different metal products. When producing structural components such as pipes, steel strip needs to be rolled into a circle.

[0003] Existing steel strip rolling mechanisms have difficulty limiting the edge of the steel strip during the rolling process. As the steel strip is continuously bent, deviations easily occur at the connection between the bent part and the subsequent steel strip, thus affecting the rolling effect.

[0004] Based on this, a steel strip rolling mechanism is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a steel strip winding mechanism to overcome the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a steel strip rolling mechanism, including a base. Two sets of support frames are symmetrically fixedly installed on one side of the front end of the upper surface of the base. A bidirectional screw is inserted through the lower part of the side of the outer surface of the two sets of support frames that are close to each other. An assembly frame is fixedly provided on the upper part of the side of the outer surface of the two sets of support frames that are close to each other. Openings are provided through the front end and rear end of the outer surface of the assembly frame.

[0007] A limiting frame is movably installed on one side of the outer surface of the two sets of support frames that are close to each other. A limiting groove is opened through one side of the outer surface of the limiting frame. The limiting frame is movably locked onto the outer surface of the assembly frame through the limiting groove. The lower part of one side of the outer surface of the limiting frame is spirally sleeved onto the outer surface of the bidirectional screw.

[0008] Two sets of support seats are symmetrically fixedly installed on one side of the rear end of the upper surface of the base. A movable groove is opened through the upper part of one side of the outer surface of the two sets of support seats. A first assembly block is movably inserted into the middle of the inner surface of the movable groove, and a second assembly block is movably inserted into the upper part of the inner surface of the movable groove. A connecting shaft is fixedly provided on the side of the outer surface of the two sets of first assembly blocks and second assembly blocks that are close to each other. A second limiting roller is movably sleeved on the outer surface of the first assembly block through the connecting shaft, and a first limiting roller is movably sleeved on the second assembly block through the outer surface of the connecting shaft.

[0009] Guide rollers are movably inserted at both ends of the middle part of the outer surface of the support base on the side closest to each other. Both ends of the guide rollers extend outward through the support base. A motor is fixedly installed on the other side of the rear end of the upper surface of the base. The output end of the motor and one end of the guide roller are both fixedly provided with transmission gears. A transmission belt is fitted onto the outer surface of the transmission gears.

[0010] As a further improvement of this utility model, a fixing bracket is fixedly installed on the other side of the rear end of the upper surface of the base, and the fixing bracket is sleeved and installed on the outer surface of the motor.

[0011] As a further improvement of this utility model, both ends of the bidirectional screw extend outward through the support frame, and both ends of the bidirectional screw are fixedly provided with rocker arms.

[0012] As a further improvement of this utility model, movable plates are movably installed on the upper and lower parts of the inner surface of the assembly frame. Cleaning pads are embedded and fixedly installed in the middle of the outer surface of the movable plates on the side closer to each other. Compression springs are fixedly installed at the four corners of the outer surface of the movable plates on the side farther from each other. The other end of the compression springs is fixedly connected to the inner surface of the assembly frame.

[0013] As a further improvement of this utility model, a first adjusting screw is spirally inserted into the middle of the upper surface of the support base. The output end of the first adjusting screw spirally passes through the first assembly block and the second assembly block and is inserted into the support base. The output end of the first adjusting screw is connected to the support base by a bearing. The inner surface of the part of the second assembly block through which the first adjusting screw passes is not in contact with the outer surface of the first adjusting screw.

[0014] As a further improvement of this utility model, an adjusting seat is fixedly provided at the end of the first assembly block away from the connecting shaft. An adjusting groove is provided through one side of the outer surface of the adjusting seat. An adjusting block is movably inserted into the upper part of the inner surface of the adjusting groove. A second adjusting screw is spirally inserted into the middle of the upper surface of the adjusting seat. The output end of the second adjusting screw spirally passes through the adjusting block and is inserted into the adjusting seat. The output end of the second adjusting screw is connected to the adjusting seat through a bearing. One side of the outer surface of the adjusting block is fixedly connected to the end of the second assembly block.

[0015] The beneficial effects of this utility model are:

[0016] This utility model can roll and bend steel strips, and limit the edge of the connection between the steel strip and the part to be bent while rolling and bending, thereby avoiding the deviation between the connection part and the part to be bent caused by the continuous bending deformation of the steel strip. This helps to ensure the stability of the rolling of the steel strip and further improves the rolling effect.

[0017] This invention can clean the surface of the steel strip by friction before rolling and bending it, thereby ensuring the cleanliness of the steel strip surface and avoiding the problem that impurities adhering to the steel strip surface will be pressured during the rolling and bending process and cover the surface of the steel strip, affecting its appearance.

[0028] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0029] Please see Figures 1-5 As shown, a steel strip rolling mechanism includes a base 1. A fixing frame 101 is fixedly installed on the other side of the rear end of the upper surface of the base 1. The fixing frame 101 is sleeved and installed on the outer surface of the motor 8. Two sets of support frames 2 are symmetrically fixedly installed on one side of the front end of the upper surface of the base 1. A bidirectional screw 201 is inserted through the lower part of the side close to the outer surface of the two sets of support frames 2. Both ends of the bidirectional screw 201 extend outward through the support frame 2. A rocker arm 202 is fixedly provided at both ends of the bidirectional screw 201.

[0030] An assembly frame 203 is fixedly installed on the upper part of the side of the outer surface of the two sets of support frames 2. The front and rear ends of the outer surface of the assembly frame 203 are both opened through. Movable plates 204 are movably installed on the upper and lower parts of the inner surface of the assembly frame 203. Cleaning pads 205 are embedded and fixedly installed in the middle of the outer surface of the side of the movable plates 204 that are close to each other. Compression springs 206 are fixedly installed at the four corners of the outer surface of the side of the movable plates 204 that are far apart from each other. The other end of the compression springs 206 is fixedly connected to the inner surface of the assembly frame 203 respectively.

[0031] It should be noted that the cleaning pad 205 is made of sponge material. Before the steel strip is rolled and bent, it needs to pass through the assembly frame 203. During the process of passing through the assembly frame 203, it will pass through the movable plate 204 at the same time. At this time, the movable plate 204 is in an open state, which will drive the cleaning pad 205 to cover the surface of the steel strip. At the same time, when the movable plate 204 is in an open state, the compression spring 206 can be subjected to force and deform to contract. At the same time, its own elasticity will drive the compression spring 206 to return to its original position. Thus, the compression spring 206 drives the movable plate 204 to control the cleaning pad 205 to fit tightly against the surface of the steel strip. When the steel strip passes through the assembly frame 203, it rubs against the cleaning pad 205 to remove impurities adhering to the surface of the steel strip.

[0032] Limiting frames 3 are movably installed on the side of the outer surface of the two sets of support frames 2 that are close to each other. A limiting groove 301 is opened through one side of the outer surface of the limiting frame 3. The limiting frame 3 is movably locked on the outer surface of the assembly frame 203 through the limiting groove 301. The lower part of one side of the outer surface of the limiting frame 3 is spirally sleeved on the outer surface of the bidirectional screw 201.

[0033] Two sets of support seats 4 are symmetrically fixedly installed on one side of the rear end of the upper surface of the base 1. Each set of support seats 4 has a movable groove 401 through the upper part of one side of the outer surface of the two sets of support seats 4. A first assembly block 402 is movably inserted into the middle of the inner surface of the movable groove 401, and a second assembly block 403 is movably inserted into the upper part of the inner surface of the movable groove 401. A connecting shaft 5 is fixedly provided on the side of the outer surface of the two sets of first assembly blocks 402 and second assembly blocks 403 respectively. A second limiting roller 502 is movably sleeved on the outer surface of the first assembly block 402 through the connecting shaft 5, and a first limiting roller 501 is movably sleeved on the outer surface of the second assembly block 403 through the connecting shaft 5.

[0034] It should be noted that the movable groove 401 facilitates the adjustment of the first assembly block 402 and the second assembly block 403. The movable adjustment of the first assembly block 402 and the second assembly block 403 can drive the second limit roller 502 and the first limit roller 501 to move up and down, thereby generating a circumferential deviation with the guide roller 7 to achieve the purpose of rolling and bending.

[0035] A first adjusting screw 404 is spirally inserted into the middle of the upper surface of the support base 4. The output end of the first adjusting screw 404 spirally passes through the first assembly block 402 and the second assembly block 403 and is inserted into the support base 4. The output end of the first adjusting screw 404 is connected to the support base 4 by a bearing. The inner surface of the part of the second assembly block 403 through which the first adjusting screw 404 passes is not in contact with the outer surface of the first adjusting screw 404.

[0036] It should be noted that the first assembly block 402 can be raised and lowered by rotating the first adjusting screw 404 clockwise and counterclockwise. Since the inner surface of the part of the second assembly block 403 through which the first adjusting screw 404 passes is not in contact with the outer surface of the first adjusting screw 404, the first adjusting screw 404 cannot control the movement and adjustment of the second assembly block 403 under this condition.

[0037] An adjusting seat 6 is fixedly provided at the end of the first assembly block 402 away from the connecting shaft 5. An adjusting groove 601 is provided through one side of the outer surface of the adjusting seat 6. An adjusting block 602 is movably inserted into the upper part of the inner surface of the adjusting groove 601. A second adjusting screw 603 is spirally inserted into the middle of the upper surface of the adjusting seat 6. The output end of the second adjusting screw 603 spirally passes through the adjusting block 602 and is inserted into the adjusting seat 6. The output end of the second adjusting screw 603 is connected to the adjusting seat 6 by a bearing. One side of the outer surface of the adjusting block 602 is fixedly connected to the end of the second assembly block 403.

[0038] It should be noted that by rotating the second adjusting screw 603 clockwise and counterclockwise, the adjusting block 602 can be controlled to slide up and down within the adjusting groove 601. The adjusting block 602 is fixedly connected to the second assembly block 403, thereby indirectly realizing the lifting and lowering control of the second assembly block 403 by the second adjusting screw 603. At the same time, the adjusting seat 6 is fixedly connected to the first assembly block 402. Under these circumstances, the lifting and lowering movement of the second assembly block 403 will not affect the first assembly block 402, so as to achieve the effect of adjusting the distance between the second assembly block 403 and the first assembly block 402. This method is suitable for use in rolling steel strips of different thicknesses.

[0039] Guide rollers 7 are movably inserted and installed at both ends of the middle part of the side close to each other on the outer surface of the support base 4. Both ends of the guide rollers 7 extend outward through the support base 4. A motor 8 is fixedly installed on the other side of the rear end of the upper surface of the base 1. A transmission gear 9 is fixedly installed at the output end of the motor 8 and one end of the guide roller 7. A transmission belt 901 is fitted and installed on the outer surface of the transmission gear 9.

[0040] It should be noted that the transmission gear 9 at the output end of the motor 8 is controlled to rotate clockwise. At this time, the rotating transmission gear 9 can drive the transmission gear 9 at the end of the guide roller 7 to rotate clockwise through the transmission engagement of the transmission belt 901, thereby indirectly controlling the guide roller 7 to perform clockwise transmission. The guide roller 7 is used to push the steel belt to move for bending and rolling operations.

[0041] In use, one end of the steel strip can first be passed through the assembly frame 203. During the process of passing through the assembly frame 203, it will simultaneously pass through the movable plate 204. At this time, the movable plate 204 is in an open state, which will drive the cleaning pad 205 to cover the surface of the steel strip. At the same time, when the movable plate 204 is in an open state, the compression spring 206 can be deformed and contracted under force. At the same time, its own elasticity will drive the compression spring 206 to return to its original position. Thus, the compression spring 206 drives the movable plate 204 to control the cleaning pad 205 to fit tightly against the surface of the steel strip. Under this condition, as the steel strip is pushed forward, the cleaning pad 205 can rub and clean the surface of the steel strip. At this time, the rocker arm 202 can be turned clockwise to control the bidirectional screw 201 to rotate clockwise, thereby pushing the limiting frame 3 sleeved on both ends of its surface to close until the limiting frame 3 contacts the edge of the steel strip to complete the limiting. At this time, the end of the steel strip can be continuously stretched until it contacts the guide roller 7.

[0042] At this point, the adjustment block 602 can be controlled to slide up and down within the adjustment groove 601 by rotating the second adjustment screw 603 clockwise and counterclockwise. The adjustment block 602 is fixedly connected to the second assembly block 403, thereby indirectly realizing the lifting and lowering control of the second assembly block 403 by the second adjustment screw 603. At the same time, the adjustment seat 6 is fixedly connected to the first assembly block 402. Under these circumstances, the lifting and lowering movement of the second assembly block 403 will not affect the first assembly block 402, so as to achieve the effect of adjusting the distance between the second assembly block 403 and the first assembly block 402. When the distance between the second limiting roller 502 installed on the second assembly block 403 and the first limiting roller 501 installed on the first assembly block 402 matches the steel strip, the steel strip can be passed through the gap between the first limiting roller 501 and the second limiting roller 502 and contact another set of guide rollers 7.

[0043] At this point, the first assembly block 402 can be lowered along the movable groove 401 by rotating the first adjusting screw 404 clockwise, thereby synchronously driving the second assembly block 403 to lower. At this time, the steel strip portion inserted between the first limiting roller 501 and the second limiting roller 502 can be pressed down synchronously. Meanwhile, the guide roller 7 is in a stable and stationary state, which can provide support for part of the steel strip. Under this condition, the steel strip can be bent. At this time, the motor 8 can be started to control the transmission gear 9 at its output end to rotate clockwise. The rotating transmission gear 9 can synchronously drive the transmission gear 9 at the end of the guide roller 7 to rotate clockwise through the transmission engagement of the transmission belt 901, thereby indirectly controlling the guide roller 7 to perform clockwise transmission, and using the guide roller 7 to push the steel strip to move.

[0044] During the advance of the steel strip, the steel strip will continuously pass through the bending area composed of the first limiting roller 501 and the second limiting roller 502. As the bending portion of the steel strip gradually increases, the steel strip will gradually form a rolled state.

[0045] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
