Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled strip steel, in particular to a strip steel pinch roller profile. Background Art

[0002] Hot-rolled coil shape quality is a key quality indicator for hot-rolled strip. Hot-rolled coil shape defects include internal convolution, staggered layers, and external convolution. Many factors influence hot-rolled coil shape quality, including hot-roller equipment accuracy, hot-rolled strip shape quality, coiler side guide control capability, pinch roll profile, and clamping force.

[0003] Regarding the pinch roller profile curve, patent publication number CN205732305U pinch roller, publication number CN202061927U a pinch roller with a composite roller profile, etc.

[0004] The pinch roller profile curves involved in the above patents are all designed to design the upper and lower pinch rollers into positive convex roller profile curves, that is, the shape of the roller is thick in the middle and thin at the edges. The common point is that the middle part is a straight section, and the two sides are oblique lines or curves. The pinch rollers use this type of curve, which is simple in shape and easy to grind. However, as the rolling amount of the strip increases, the wear of the pinch rollers will increase accordingly. The traditional detection of wear is to manually measure and calculate the wear amount using a ruler after the pinch rollers have worked for a certain period of time, or when it is observed that the strip is deviating, it means that the pinch rollers are worn out, and the pinch rollers are replaced accordingly. Utility Model Content

[0005] The purpose of the utility model is to provide a strip pinch roller profile to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a strip steel pinch roller, comprising a middle roller, end rollers being provided at the ends of the middle roller, and further comprising:

[0007] A prompting member is provided inside the middle roller and is used to indicate the degree of wear of the middle roller;

[0008] An annular groove is provided on the outer wall of the middle roller and is used for installing the prompting member.

[0009] Preferably, the end of the middle roller is fixedly connected to the end of the end roller, and the vertical cross-section of the annular groove is circular.

[0010] Preferably, the prompt member includes a prompt layer, and an elastic ring for expansion and pulling is fixedly connected to the inner wall of the prompt layer.

[0011] Preferably, an adhesive layer for bonding the elastic ring and the annular groove is fixedly connected to the inner wall of the elastic ring.

[0012] Preferably, the middle roller and the end rollers form a positive crown roller type.

[0013] Preferably, the length of the middle roller is 260 mm, and the length of the end roller is 270 mm.

[0014] Preferably, the middle roller is cylindrical, and the end rollers are truncated cone-shaped.

[0015] Technical effects and advantages of this utility model:

[0016] The utility model utilizes the design of the middle roller and the prompting member. When the middle roller and the end rollers rotate to transmit the strip, the middle roller will be worn. When the middle roller continues to rotate, lines appear on the surface of the strip due to friction with the prompting layer, it means that the wear of the middle roller has reached the specified value and the pinch roller needs to be replaced. This method does not require manual measurement and can be discovered before the strip deviates, which saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS
