Device and method for measuring rolling line height of universal rolling mill

Abstract

The invention discloses a device and method for measuring the rolling line height of a universal rolling mill, and belongs to the technical field of measuring devices and methods. The device and method are used for measuring the rolling line height of the universal rolling mill. According to the technical scheme, a horizontal roller hole pattern measuring plate of a horizontal measuring plate is matched with a roller gap between an upper horizontal roller and a lower horizontal roller in shape; a hole pattern bayonet is formed in the plate face of the side, opposite to the end face of a head vertical roller, of a vertical roller measuring plate and matched with a hole pattern in the end face of the head vertical roller; a movable plate of the horizontal measuring plate and the vertical roller measuring plate are opposite in parallel and are in sliding connection; the movable plate of the horizontal measuring plate and the vertical roller measuring plate are connected and then placed inthe roller gap between the side face of the upper horizontal roller and the end face of the head vertical roller and the roller gap between the side face of the lower horizontal roller and the end face of the head vertical roller; a digital display magnetic grating ruler is connected with the horizontal measuring plate and the vertical roller measuring plate; and a calibration block is located between the horizontal measuring plate and the vertical roller measuring plate. The rolling line height of the hole pattern formed by the roller gaps of the horizontal rollers and the head vertical roller can be measured, production adjustment is guided through measurement parameters of the digital display magnetic grating ruler, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a device and method for measuring the height of a rolling line of a universal rolling mill, and belongs to the technical field of measuring devices and methods. Background technique [0002] In the production of rails, the universal rolling mill is the core equipment for rail production. The universal rolling mill has four rolls: horizontal upper roll, horizontal lower roll, head vertical roll, and bottom vertical roll. Their relative positions need to be calibrated before production. The calibration effect The quality of the product directly affects the quality of the produced product. [0003] In the production process, the vertical roll pass centerline should be at the same height as the roll gap centerline of the horizontal upper roll and the horizontal lower roll. Due to the influence of factors such as roll assembly gap, vertical roll device gap, wear plate wear and other factors, there is still a large deviation in the ...

[0003] In the production process, the vertical roll pass centerline should be at the same height as the roll gap centerline of the horizontal upper roll and the horizontal lower roll. Due to the influence of factors such as roll assembly gap, vertical roll device gap, and wear plate wear, there is still a large deviation in the height of the rolling line after calibration
