Description

Technical Field

[0001] This utility model relates to the field of aluminum foil rolling technology, specifically to a rolling mill roll system parallelism measuring device. Background Technology

[0002] In aluminum foil rolling production, the parallelism of the rolling mill roll system is one of the key factors affecting product quality. The parallelism of the roll system referred to here mainly refers to the parallelism between the work rolls and the guide rolls (such as wrap rolls) on the inlet and outlet sides. If there is non-parallelism among the rolls, it will lead to uneven stress on the aluminum foil during rolling, resulting in serious quality defects such as sheet tilting and unilateral loosening, significantly reducing the yield.

[0003] Currently, the traditional measurement method in the industry involves removing the key component—the work roll—from the mill after it has stopped, and then using the exit side of the mill as a reference, measuring tools are used to check the relative positions of the relevant roll system. This method has several obvious drawbacks: First, the operation is cumbersome, requiring the removal of the work roll, which consumes a lot of manpower and time, resulting in long equipment downtime and seriously affecting production efficiency; second, due to the inconvenience of measurement, it cannot be performed frequently, making it difficult to detect and correct minor changes in the parallelism of the roll system in a timely manner, which is not conducive to the stable control of product quality. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a rolling mill roll parallelism measuring device. This device eliminates the need to remove the work rolls from the rolling mill stand and allows for direct measurement during short equipment downtime or maintenance windows. It facilitates regular or irregular inspection of roll parallelism, helps to promptly detect roll parallelism deviations, and enables adjustments to the roll system. This simplifies the operation process, shortens inspection time, reduces production losses due to downtime, and improves production efficiency, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling mill roll parallelism measuring device, comprising a telescopic rod, one end of which is fitted with a cylindrical nylon rod perpendicular to it, and the other end of which is fitted with an mounting plate. A dial indicator is provided on the lower side of the mounting plate, with the dial indicator pointing towards the cylindrical nylon rod.

[0006] As a preferred embodiment of this utility model, the telescopic rod includes an outer seamless steel pipe and an inner seamless steel pipe, with the inner seamless steel pipe movably inserted into the outer seamless steel pipe.

[0007] As a preferred embodiment of this utility model, the cylindrical nylon rod is mounted on the outer seamless steel pipe, and a screw is provided at the corresponding part of the cylindrical nylon rod and the outer seamless steel pipe. The inner cavity of the outer seamless steel pipe and the screw is a threaded cavity, and the screw is threadedly connected to the outer seamless steel pipe.

[0008] As a preferred technical solution of this utility model, the outer seamless steel tube has a screw hole on the side away from the cylindrical nylon rod, and the screw hole is internally threaded with an adjusting screw for locking the inner seamless steel tube.

[0009] As a preferred embodiment of this utility model, the mounting plate is installed on the inner seamless steel pipe, and the dial indicator head is set parallel to the inner seamless steel pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The mill roll parallelism measuring device of this utility model does not require the work rolls to be removed from the mill stand. It can be used to measure directly during short equipment shutdowns or maintenance windows, which is convenient for periodic or irregular inspection of roll parallelism. It helps to detect roll parallelism deviations in a timely manner, thereby adjusting the roll system. It simplifies the operation process, shortens the inspection time, reduces production losses caused by downtime, and improves production efficiency. Attached Figure Description
