Description

Technical Field

[0001] The utility model relates to the field of roll bending cylinder design, in particular to a new type of hot rolling roll bending cylinder. Background Art

[0002] Hot rolling is relative to cold rolling. Cold rolling is rolling performed below the recrystallization temperature, while hot rolling is rolling performed above the crystallization temperature. Hot rolling can improve the processing performance of metals and alloys, that is, it can break up the coarse grains in the casting state, significantly heal cracks, reduce or eliminate casting defects, transform the cast structure into a deformed structure, and improve the processing performance of the alloy.

[0003] In the prior art, the upper cover and the oil block of the bending cylinder of the hot plate finishing mill are two separate parts. There are rod side seals and cavity side seals between the upper cover and the oil block. The seals are easily damaged and fail, causing oil leakage accidents. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the seal is easily damaged and becomes ineffective, resulting in an oil leakage accident.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a new type of hot rolling bending cylinder, including an upper cylinder body, a lower cylinder body, a piston rod, a spherical pad and a connecting rod. The lower cylinder body is slidably arranged on the upper cylinder body, the piston rod is slidably arranged in the upper cylinder body, the spherical pad is provided with two groups, the spherical pad is installed on the piston rod and the lower cylinder body, the connecting rod is slidably contacted between the two groups of spherical pads, and a cover body oil circuit block is installed on the upper cylinder body.

[0006] Furthermore, a first end cover is installed on the lower cylinder body, and the first end cover is located outside the connecting rod.

[0007] Furthermore, a second end cover is installed on the piston rod, and the second end cover is located outside the connecting rod.

[0008] Furthermore, an upper cylinder end cover is installed on the upper cylinder body, and the upper cylinder end cover is slidably arranged outside the connecting rod.

[0009] The beneficial effects achieved by the utility model with the above structure are as follows: the upper cover and the oil circuit block in the original design are integrated and installed on the upper cylinder body, thereby eliminating the risk of oil leakage and reducing the probability of failure.
