Description

Technical Field

[0001] The utility model belongs to the technical field of rolling mill vibration reduction equipment, in particular to a rolling roller with an inertial damping vibration absorbing device. Background Art

[0002] The high-speed and stable operation of plate and strip mills is the core key technology to ensure the stability of the production process and product quality, and is a major technical problem that needs to be solved by intelligent manufacturing in the steel industry. In recent years, the products of steel enterprises have been continuously upgraded, but the rolling mill equipment has not been updated enough and the control technology is not perfect. The rolling mill has been running at high speed and high load for a long time. The mismatch between the rolling mill equipment, process and products has become increasingly prominent, resulting in frequent product quality problems caused by mill vibration in both the plate and strip mills introduced from abroad and independently designed, which seriously affects the rolling process and product quality stability.

[0003] With the adoption of a large number of new processes and technologies, the vibration of existing rolling mills in the process of producing plates has shown many new trends, mainly including vertical vibration, torsional vibration, horizontal vibration, nonlinear vibration and multi-state coupling vibration of the roll system. The above vibrations often lead to roller surface peeling, roll breakage, workpiece chatter marks and bearing damage, which in turn affect the working efficiency of the rolling mill. Utility Model Content

[0004] In order to solve the shortcomings and deficiencies of the prior art, a rolling mill with an inertial damping vibration absorption device is provided, thereby solving the problem that in the process of producing plates in the existing rolling mill, vibration causes roller surface peeling, roller breakage, workpiece vibration marks and bearing damage, thereby affecting the working efficiency of the rolling mill.

[0005] In order to achieve the purpose of the utility model, a rolling roller with an inertial damping vibration absorbing device is provided, comprising a rolling roller, wherein the inertial damping vibration absorbing mechanism is evenly arranged with the axis as the center in the roller shaft body of the rolling roller, and the inertial damping vibration absorbing mechanism comprises a high-density tungsten damper, and the tips at both ends of the high-density tungsten damper are respectively connected to one end of a carbon fiber rope, and the other end of the carbon fiber rope is fixedly connected to the center position of a sealing plug, and a high-strength tube is arranged on the opposite side of the two sealing plugs.

[0006] As a further improvement of the above solution, a plurality of through holes are evenly opened in the roller shaft body of the rolling roller with the axis as the center, and the inertial damping vibration absorbing mechanism is inserted into the through holes.

[0007] As a further improvement of the above solution, the sealing plug and the high-strength tube are connected by threaded fitting.

[0008] As a further improvement of the above solution, the diameter of the high-density tungsten damper gradually decreases from the middle to both ends.

[0009] As a further improvement of the above solution, the carbon fiber rope is made of high-strength, corrosion-resistant and high-temperature-resistant carbon fiber rope.

[0010] The beneficial effects of the utility model are:

[0011] Compared with the prior art, the utility model provides a roller with an inertial damping vibration absorption device. When the roller vibrates during operation, the inertial damping vibration absorption mechanism installed in the roller through hole vibrates, which is transmitted to the carbon fiber rope through two sealing plugs. The high-density tungsten damper vibrates with a limited amplitude in the high-strength tube driven by the carbon fiber rope. The device has a compact structure, uniform and stable transmission movement, and the vibration reduction effect changes with the change of the roller vibration. It can effectively reduce the vibration of the rolling mill, reduce roller surface peeling, roller breakage, and the generation of vibration marks on rolled parts, and improve the quality of the products produced by the rolling mill; at the same time, the device is more convenient to use and can achieve an ideal vibration reduction effect without external intervention.

The inertial damping vibration absorbing mechanism 5 includes a high-density tungsten damper 1, and the diameter of the high-density tungsten damper 1 gradually decreases from the middle to both ends. The tips of the two ends of the high-density tungsten damper 1 are respectively connected to one end of a carbon fiber rope 3, and the other end of the carbon fiber rope 3 is fixedly connected to the center position of a sealing plug 2.
