Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil pressing, and in particular relates to a steel coil pressing device. Background Art

[0002] The steel strip produced by the hot-rolled strip mill needs to be further sampled and inspected to determine whether the performance indicators of the steel strip meet the acceptance requirements. The steel coil to be sampled is placed on a V-shaped saddle, and then the outermost layer of the steel coil is cut and sampled by a flame cutting machine. Steel coils, especially high-strength steel coils with a thickness of 12.7 to 25.4 mm and a tensile strength of σb≤1200Mpa, have the following technical problems after unwinding: First, there is a risk of the outer layer of steel coils being unwound and loosened at the moment of removing the straps and re-bundling after sampling. Second, the high-strength steel coils cannot be rewound tightly after sampling. Due to the high yield strength of high-strength steel coils, relying solely on the self-weight of the steel coils to rewind easily leads to excessive gaps between the outer and inner strips after rewinding, and thus the bundling quality and safe lifting of the steel coils cannot be guaranteed.

[0003] In order to prevent the outer layer of steel coil from springing open and unwinding, the Chinese patent document with the authorization announcement number CN216226209U discloses a steel coil pressing roller device with a movable counterweight, which includes a frame, a pressing roller arm, a pressing roller, a counterweight trolley, a counterweight block, a limit switch and a hydraulic cylinder, etc. The pressing roller arm with a rotating shaft is installed on the frame through a support and connected by bolts; the pressing roller is installed on the pressing roller arm through a bearing seat and connected by bolts; the counterweight trolley is installed in the slideway of the pressing roller arm and can walk in the slideway of the pressing roller arm; the counterweight block is placed on the counterweight trolley; the limit switch is installed on the frame to control the position of the pressing roller arm; the hydraulic cylinder connects the frame and the pressing roller arm to drive the pressing roller arm to swing. The pressing roller arm swings around the rotating shaft under the drive of the hydraulic cylinder, driving the pressing roller to lift or fall, and completing the compression of the steel coil according to work needs. Since the pressing roller arm needs swinging space, a larger installation space is required. Utility Model Content

DETAILED DESCRIPTION

[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] The steel coil pressing device comprises a frame 1, a pressing roller support 3 and a pressing roller 2, wherein the frame 1 is connected to the pressing roller support 3 via a linear drive mechanism 5; the linear drive mechanism 5 is extended or shortened along an inclined linear drive direction L2; both ends of the pressing roller 2 are mounted on the pressing roller support 3 via a bearing seat 4; the axial direction L1 of the pressing roller 2 is perpendicular to the linear drive direction L2 of the linear drive mechanism 5.

[0032] Both ends of the pressure roller 2 are mounted on the pressure roller support 3 through the bearing seat 4, and the end of the pressure roller 2 is rotatably connected to the bearing seat 4, which is a prior art. The bearing seat 4 is connected to the pressure roller support 3 by bolts. The pressure roller support 3 can be an I-beam, a steel rectangular tube, etc. The frame 1 provides installation support for the linear drive mechanism 5, and the linear drive mechanism 5 drives the pressure roller 2 to perform linear reciprocating motion along the inclined linear drive direction L2, so that the pressure roller 2 can approach or move away from the steel coil 15. The linear drive mechanism 5 drives the pressure roller 2 to be recovered upward along the linear drive direction L2, providing an operating space for the lifting of the steel coil 15. The steel coil 15 is lifted on two rollers 16 arranged at intervals through the lifting equipment. After the lifting is completed, the linear drive mechanism 5 drives the pressure roller 2 to extend downward along the linear drive direction L2.

[0033] Working condition 1: If Figure 6 As shown, it includes rollers, auxiliary rollers and a set of steel coil pressing device. The steel coil 15 is hoisted on two rollers 16 arranged in pairs, and the steel coil 15 is wound from the outer layer to the inner layer in the counterclockwise direction L3. An auxiliary roller 17 is also pressed on the top of the steel coil 15, and the roller 2 of the steel coil pressing device is located above the right side of the steel coil 15. The axial direction of the steel coil 15, the axial direction of the roller 16 and the axial direction of the auxiliary roller 17 are all parallel to the axial direction L1 of the roller 2. The two rollers 16 rotate in the same direction, and the steel coil 15 rotates counterclockwise around its own axis under the action of the roller 16 and the auxiliary roller 17. Before the steel coil 15 is untied from the strap, the roller surface of the roller 2 maintains a certain distance from the outer surface of the steel coil 15. When the steel coil 15 rotates to the point where the belt tail 1501 is located at a suitable distance below the roller 2, the strap is removed, and the belt tail 1501 pops open, and its surface contacts the roller surface of the roller 2. Then the tape tail 1501 is sampled.

[0034] Working condition 2: Figure 7As shown, there are rollers and two sets of steel coil pressing devices. The steel coil 15 is hoisted on two rollers 16 arranged in pairs, and the two sets of steel coil pressing devices are arranged symmetrically with the axial direction of the steel coil 15 as the symmetry axis. The axial direction of the steel coil 15 and the axial direction of the rollers 16 are both parallel to the axial direction L1 of the pressing roller 2. The roller surface of one pressing roller 2 presses on the outer surface of the upper left side of the steel coil 15, and the roller surface of the other pressing roller 2 presses on the outer surface of the upper right side of the steel coil 15. The two rollers 16 rotate in the same direction, and under the action of the friction between the roller surfaces of the rollers 16 and the pressing roller 2 and the outer surface of the steel coil 15, the steel coil 15 is driven to rotate around its own axis. When the tail 1501 of the belt is in a suitable position below one of the rollers 16, the belt stops rotating. Then the belt tail 1501 is sampled. The steel coil 15 can rotate clockwise around its own axis, or counterclockwise around its own axis.

[0035] It can be concluded from the above two working conditions that the steel coil pressing device of the utility model can effectively prevent the steel coil 15 from loosening and ensure the quality of the re-bundling of the steel coil 15 after sampling. Compared with a steel coil pressing roller device with a movable counterweight in the background technology, the installation space is reduced.
