Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of preventing the head of a metal target from warping during rolling, and in particular to a rolling mill anti-warping guide device. BACKGROUND

[0002] In the field of metal targets and semiconductors, rolling is an important process for material forming. In the production of rolling, a product needs to be continuously rolled in multiple passes back and forth, or enter the guide of another rolling mill from the guide of one rolling mill. Therefore, if the product warps during rolling, not only will the rolled piece not be able to be smoothly rolled, but also accidents will occur and there is a risk of the rolled piece being scrapped. In order to solve the above problems, an anti-warping device needs to be installed on the rolling mill.

[0003] In the prior art, a patent (CN209680807U) discloses an adjustable strip steel anti-warping device. The device includes a fixed plate, a lifting plate, and an anti-warping pressing plate arranged along the conveying direction of the strip steel. The fixed plate is provided with a hydraulic cylinder in the vertical direction. The output rod of the hydraulic cylinder is fixedly connected with the lifting plate. The two sides of the fixed plate are provided with mounting holes. The top of the anti-warping pressing plate is provided with a movable groove in cooperation with the lifting plate. The movable groove is provided with a vertical guide groove. The lifting plate is provided with a vertical guide block in cooperation with the vertical guide groove. The lifting plate is provided with a threaded hole. A threaded hole is screwed with an adjusting screw. The top end of the adjusting screw is provided with a hand wheel. The bottom end of the adjusting screw is rotationally connected with the anti-warping pressing plate. To some extent, the above anti-warping problem is solved. However, the device uses a plate-shaped structure bottom plate for guiding. The friction between the rolled piece and the plate-shaped structure contact part is large, which can easily cause cracks on the upper surface of the plate due to friction, affecting the surface quality and forming quality of the plate.
