Description

Technical Field

[0001] This utility model relates to the technical field of pressure adjustment devices, specifically a hydraulically driven prestressing continuous adjustment device for short stress line rolling mills. Background Technology

[0002] The roll gap adjustment device (also known as the roll gap adjustment device) of the short stress line rolling mill for wire and bar products mainly consists of a hydraulic motor, rigid connector, worm gear, worm wheel, bevel gear shaft and bevel gear and other transmission components, tie rod, rolls, upper and lower bearing seats, and roll frame.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 201969730U), "This utility model discloses a novel reduction adjustment device for a short stress line rolling mill, which includes a transmission system driven by a hydraulic motor, four tie rods at both ends of the rolling mill, and rolling rolls." The upper and lower bearing seats, the roll mill frame, and the tie rod are connected to the bevel gears in the transmission system. The key feature is that surfaces A and B of the tie rod located between the roll mill frame and the upper and lower bearing seats are covered with a chrome-plated layer. This chrome plating improves the wear and corrosion resistance of the tie rod surface. Furthermore, this invention uses polytetrafluoroethylene (PTFE) as the sealing ring in the cavities at both ends of the bearing seat, and its contact surface with the tie rod is changed from a straight surface to a bevel. A telescopic protective sleeve is also added to the surface of the tie rod between the upper and lower bearing seats and the end caps on the roll mill frame. This invention prevents iron oxide scale, water, and oil mixtures from entering the reduction adjustment device and obstructing the rotation of the tie rod, thus effectively preventing the reduction adjustment device from failing and improving the reliability of the rolling mill operation.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model adds a telescopic protective sleeve to the surface of the tie rod between the upper and lower bearing seats and the end caps on the roll mill stand to prevent large pieces of iron oxide scale from adhering to the tie rod surface, thus reducing the impact of water, oil, and iron oxide scale mixtures on the working surface. In actual use, since the device uses an elastic damper instead of a spring to absorb shock and buffer, the damping spring stretches or contracts when the bearing seat position is adjusted, which cannot adequately meet the linear shock reduction adjustment requirements for different types of wire rods. Therefore, it is necessary to improve the device to provide a hydraulically driven prestressed continuous adjustment device for short-stress wire mills to solve the above problems.

[0028] While existing technologies using elastic dampers instead of springs can achieve shock absorption and buffering, the damping springs stretch or contract when the bearing housing position is adjusted, making it unsuitable for linear shock reduction adjustment of different types of wire rods. This embodiment provides a hydraulically driven continuous prestress adjustment device for short-stress wire mills. Please refer to [link to relevant documentation]. Figure 1-5 This utility model provides a technical solution: a hydraulically driven prestressed continuous adjustment device for a short stress line rolling mill, including an installation frame 1, a support frame 2 fixedly connected to the outside of the installation frame 1, an installation plate 3 fixedly connected to the outside of the installation frame 1, a protective box 4 fixedly connected to the top of the installation frame 1, a connecting box 7 fixedly connected to the outside of the support frame 2, an adjustment and shock absorption mechanism 5 provided inside the connecting box 7, and a hydraulic line rolling mechanism 6 provided on the right side of the protective box 4.

[0029] The damping mechanism 5 includes an adjustment component 51 and a damping component 52, with the damping component 52 located at the end of the adjustment component 51 away from the connecting box 7.

[0030] Furthermore, the adjustment assembly 51 includes a connecting platform 511, which is fixedly connected inside the connecting box 7. A bidirectional threaded rod 512 is rotatably connected inside the connecting platform 511. A limit rod 514 is fixedly connected inside the connecting platform 511. A movable plate 513 is slidably connected to the outside of the limit rod 514, which facilitates the adjustment of the position of the movable plate 513, thereby satisfying the damping linearity of the adjusting spring 521 and the damping rod 522.

[0031] Furthermore, the movable plate 513 is threadedly connected to the bidirectional threaded rod 512, and the connecting platform 511 and the movable plate 513 are provided with grooves at corresponding positions, and the movable plate 513 is slidably connected inside the groove, which facilitates a more stable adjustment process.

[0032] Furthermore, the shock absorption assembly 52 includes a spring 521, which is fixedly connected to the end of the movable plate 513 away from the connecting box 7. A damping rod 522 is fixedly connected to the end of the movable plate 513 away from the connecting box 7. A sliding plate 523 is fixedly connected to the end of the damping rod 522 away from the movable plate 513. A connecting block 527 is slidably connected inside the connecting box 7. A first fixing block 525 is fixedly connected to the end of the sliding plate 523 near the connecting block 527. A connecting rod 526 is rotatably connected inside the first fixing block 525. A second fixing block 528 is fixedly connected to the end of the connecting block 527 near the connecting rod 526. A sliding rod 524 is fixedly connected inside the connecting box 7. This facilitates the damping and balancing of the vibration generated by the processing of the bearing seat 65, thereby increasing the overall service life of the device.

[0033] Furthermore, the second fixing block 528 has a groove at the corresponding position of the connecting rod 526, and the connecting rod 526 is rotatably connected inside the groove. The slide plate 523 is slidably connected to the slide rod 524, the spring 521 is fixedly connected to the slide plate 523, and the movable plate 513 is slidably connected to the slide rod 524, which facilitates a more stable shock absorption process. Example

[0034] Based on Embodiment 1, the existing technology often encounters resistance during the rotation of the pull rod. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 6 Furthermore, in conjunction with Embodiment 1, the hydraulic wire rolling mechanism 6 includes a hydraulic motor 61, which is fixedly connected to the right side of the protective box 4. The output end of the hydraulic motor 61 extends through the protective box 4 and is fixedly connected to a worm gear 62 inside. A pull rod 63 is rotatably connected inside the mounting frame 1. A worm wheel 64 is fixedly connected to the top of the pull rod 63. A bearing seat 65 is threadedly connected to the outside of the pull rod 63, which facilitates the adjustment of the movement of the bearing seat 65, thereby satisfying the need to process wires of different sizes while continuously adjusting the prestress.

[0035] Furthermore, there are four pull rods 63, with each pair of pull rods 63 forming a group. The two groups of pull rods 63 are symmetrically distributed with the center line of the front of the mounting frame 1 as the axis of symmetry, which facilitates a more stable adjustment process.

[0036] In actual operation, when this device is used, the operator first installs the mounting frame 1 to the designated position using the mounting plate 3. The hydraulic motor 61 then rotates the worm gear 62, which, in conjunction with the worm wheel 64, causes the pull rod 63 to rotate inside the mounting frame 1. This, combined with the dust cover positioned inside the mounting frame 1 relative to the pull rod 63, adjusts the movement of the bearing seat 65. In conjunction with the rollers, the operator rotates the bidirectional threaded rod 512. The rotation of the bidirectional threaded rod 512, in conjunction with the limit rod 514, allows the moving rollers to move. The moving plate 513 moves to satisfy the damping linearity of the adjusting spring 521 and the damping rod 522. After adjustment, when the rollers roll the wire, the vibration generated by the bearing seat 65 causes the connecting block 527 to move. The movement of the connecting block 527 causes the second fixed block 528 to move. Together with the connecting rod 526 and the first fixed block 525, the sliding plate 523 slides outside the sliding rod 524. Together with the damping rod 522 and the spring 521, the vibration generated by the processing of the bearing seat 65 is reduced and balanced.
