Description

Technical Field

[0001] The utility model relates to the technical field of plate shape measurement, in particular to a cone sleeve type plate shape roller. Background Art

[0002] Flatness is essentially the transverse distribution of longitudinal residual stress within the strip. This transverse distribution of strip tension, measured by built-in sensors, is a key quality indicator for cold-rolled strip. The flatness detection system is the core equipment for online flatness detection and closed-loop control, and the flatness roller is a key component of the entire system. Depending on the roller surface, the flatness roller can be divided into two types: segmented with seams and seamless, full-roll types.

[0003] ABB of Switzerland represents the market for slotted, segmented plate rollers. These rollers consist of a roller body and multiple roller rings. Four axial slots are cut into the roller body for sensors. The roller rings are individually fitted onto the roller body using interference heating and pressed against the sensors, creating a preload on the sensors. Gaps are left between the roller rings to prevent interference with sensor signals. However, the gaps between the roller rings can allow oil and dust to enter under harsh production conditions, affecting sensor accuracy. Furthermore, the gaps between the roller rings can scratch the strip.

[0004] Representative brands of seamless, full-roll plate-shaped rollers are Germany's BFI and Yanshan University. Multiple axial, eccentric holes are bored into the roller body, and sensor components are placed inside these holes one by one. However, the disadvantages of this method are that the eccentric holes in the plate-shaped roller require high machining precision, which is difficult. Furthermore, the sensor measurements interfere with each other, requiring decoupling through post-processing algorithms, resulting in low measurement accuracy.

[0005] In summary, the existing flatness rollers are difficult to process and assemble, sensors easily interfere with each other, have low measurement accuracy, and are prone to scratching the strip, etc., and cannot meet the requirements of high-precision flatness measurement. Summary of the Invention

[0006] In view of the above problems existing in the prior art, the purpose of the invention of the utility model is to provide a tapered sleeve type plate shape roller to improve the plate shape measurement accuracy.

[0007] In order to achieve the above-mentioned purpose of the invention, the conical sleeve type plate roller of the utility model mainly includes a roller core, a thin-walled roller sleeve is passed through the outside of the roller core, and a plurality of slotted conical rings and fixing conical rings are installed between the roller core and the thin-walled roller sleeve.

[0010] Furthermore, a protruding screw is provided at one end of the pressure cap, and an external thread is provided on the screw. The screw passes through the inner hole of the sensor to fix the sensor on the slotted cone ring.

[0011] Furthermore, the outer surface of the tightening cone ring is a conical surface, and the inside is a through hole. Keyway 2 and keyway 3 are respectively provided on the outer surface and the through hole wall. Keyway 3 cooperates with the long keyway on the roller shaft core. The tightening cone ring is fixed to the roller shaft core through the long key. The outer conical surface of the tightening cone ring is precisely fitted with the inner conical surface of the slotted cone ring to support the slotted cone ring.

[0012] Furthermore, the gland is provided with evenly distributed radial slots for the sensor transmission line to pass through, and the end face of the gland is provided with evenly distributed axial bolt through holes and three threaded holes. The adjusting bolt passes through the bolt through holes to connect the gland to the roller core, and the adjusting bolt is used to squeeze the fixing cone ring through the gland to expand the slotted cone ring, and the fixing bolt passes through the three threaded holes to fix the retaining ring to the gland.

[0013] The tapered sleeve plate-shaped roller of the utility model is usually installed at the outlet of the rolling mill, and the plate strip is placed on the outer wall of the thin-walled roller sleeve of the tapered sleeve plate-shaped roller. If the surface of the plate strip is uneven, the thin-walled roller sleeve will lift the plate strip to produce an angle, forming a wrap angle.
