Description

Technical Field

[0001] The utility model belongs to the technical field of rolling rollers, and more specifically, particularly relates to a high-nickel, chromium, and molybdenum centrifugal composite rolling roller suitable for rolling bars and wires. Background Art

[0002] Rollers are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. Rollers are important parts of rolling mills in steel mills. They use the pressure generated by a pair or a group of rolls to roll steel. They mainly bear the dynamic and static loads, wear and temperature changes during rolling, and are mainly divided into hot rolls and cold rolls.

[0003] Based on the above, the inventors have discovered the following problems: after continuous operation, the surface of the roller will easily develop grooves or some bevels, which may easily affect subsequent processing operations. The existing operation is to install an isolation sleeve on the surface of the roller, but the isolation sleeve is prone to deviation as it rotates during operation, and the product to be processed may easily act on the roller body, causing damage to the roller body.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a high nickel-chromium-molybdenum centrifugal composite roller suitable for rolling bars and wires is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and function of the utility model, a high nickel-chromium-molybdenum centrifugal composite roller suitable for rolling bars and wires, are achieved by the following specific technical means:

[0006] A high-nickel, chromium, and molybdenum centrifugal composite roller suitable for rolling bars and wires comprises a roller body, both ends of the roller body are clamped and installed with clamps, a plurality of adjustment limit columns are equidistantly installed on the surface of the clamp, a protective sleeve is sleeved on the surface of the roller body, and the roller body is assembled and installed with the protective sleeve by means of the adjustment limit column clamp.

[0007] Furthermore, the inner wall of the clamp is provided with a plurality of grooves, the grooves are provided with limiting grooves, a protruding block is slidably installed in the limiting grooves, a spring is installed in one side of the protruding block in the groove, and an anti-slip pad is provided on the surface of the protruding block.

[0008] Furthermore, the adjustment limit column includes a sleeve seat, and a through hole groove is penetrated through the side wall of the sleeve seat.

[0009] Furthermore, a connecting rod is inserted and installed on the top of the sleeve seat, a chamber is opened on the side wall of the connecting rod, a limiting groove is opened on the inner wall of the chamber, a T-block is slidably installed between the limiting grooves, one side of the T-block is installed with spring 2, and the diameter of the T-block is adapted to the diameter of the through hole groove.

[0010] Furthermore, the clamp, the sleeve seat and the connecting rod are all made of metal materials, and the surfaces of the clamp, the sleeve seat and the connecting rod are all provided with a galvanized layer.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Through the use of the groove and the protruding block in conjunction with the spring, when the clamp body is clamped on the roller body of different diameters, the spring can make the side wall of the protruding block contact the surface of the roller body, so that the clamp can be assembled on rollers of different types and sizes, greatly improving the overall adaptability and practicality.
