Description

Technical Field

[0001] The utility model relates to a loose-fitting roller device which is easy to replace and belongs to the technical field of metallurgical industry. Background Art

[0002] When rolling small specifications, the ground roller only plays a guiding role because the tension is adjusted by the set-up roller. After the set-up, the red steel does not contact the ground roller. When rolling specifications above φ14, the rolling mill is in an empty state, and the red steel will always pass through the set-up. At present, since the ground roller bearings are lubricated with dry oil, when rolling small specifications, they are not used for a long time, causing the dry oil to solidify and the rotation to be inflexible. The ground roller needs to be replaced in time, otherwise the red steel head will cause scratches or steel pile accidents when passing through. However, since the bearing seat fixing screws are internal threads, the inner bearing seat space is small and cannot be replaced in a short time. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a conveniently replaceable loose roller device for the above-mentioned prior art, which has a simple structure and is convenient to disassemble and assemble, and can quickly replace the loose roller to avoid abrasion or steel piling accidents.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a kind of easily replaceable slip-on roller device, comprising a slip-on body, wherein the inlet and outlet of the slip-on body are respectively provided with detachable slip-on rollers, and a lifting roller is provided between the two detachable slip-on rollers; the detachable slip-on rollers respectively comprise slip-on roller wheels, a roller shaft is provided at the center of the slip-on roller wheels, and a bearing is provided between the roller shaft and the slip-on roller wheels; two support cylinders are provided on the side of the slip-on body: an inlet support cylinder and an outlet support cylinder, one end of the roller shaft is penetrated by the support cylinder on the corresponding side, and a through mounting groove is provided on the roller shaft exposed from the support cylinder, and a mounting piece is inserted into the mounting groove so that the roller shaft is fixed in the support cylinder.

[0005] An inlet guide plate is arranged at the inlet end of the loop body.

[0006] The mounting piece is an inclined iron.

[0007] The bearing is a 6015 bearing.

[0008] The looper roller is made of Cr25NiMoWVRe.

[0009] Compared with the prior art, the utility model has the advantages of: a looping roller device that is easy to replace. If the looping roller needs to be replaced, the roller shaft can be removed from the support tube by knocking out the inclined iron, so as to facilitate the replacement of the looping roller. The utility model has a simple structure and is easy to disassemble and assemble. The looping roller can be quickly replaced, avoiding scratches or steel pile accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic diagram of a loose-fitting roller device that is easy to replace according to an embodiment of the utility model;

[0011] In the figure, 1 is the loop body, 2 is the loop roller, 3 is the inlet guide plate, 4 is the roller shaft, 5 is the inclined iron, 6 is the support cylinder, and 7 is the loop roller. DETAILED DESCRIPTION

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] like Figure 1 As shown, in this embodiment, a looping roller device that is easy to replace includes a looping body 1, and a detachable looping roller is provided at the inlet and outlet of the looping body 1, and a lifting roller 7 is provided between the two detachable looping rollers. The detachable looping rollers include a looping roller wheel 2, and a roller shaft 4 is provided at the center of the looping roller wheel 2, and a bearing is provided between the roller shaft 4 and the looping roller wheel 2. Two support cylinders 6 are provided on the side of the looping body 1: an inlet support cylinder and an outlet support cylinder, and one end of the roller shaft 4 is penetrated by the support cylinder 6 on the corresponding side, and the outer periphery of the roller shaft 4 exposed from the support cylinder 6 is provided with a mounting groove that passes through the left and right, and an inclined iron 5 is inserted in the mounting groove, so that the roller shaft 4 is fixed in the support cylinder 6. If the looping roller wheel 2 needs to be replaced, the inclined iron 5 can be knocked out to remove the roller shaft 4 from the support cylinder 6, so as to facilitate the replacement of the looping roller.

[0014] An inlet guide plate 3 is arranged at the inlet end of the looper body 1 to guide the red steel entering the looper body.

[0015] The bearings are 6015 bearings, which are not easy to get stuck and can rotate flexibly; the material of the loose roller is Cr25NiMoWVRe, which is not easy to wear, has a longer service life and reduces the replacement cycle.

[0016] The present invention has a simple structure and is easy to disassemble and assemble, and can quickly replace the loose-fitting ground roller, thus avoiding abrasion or steel piling accidents.

[0017] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
