Coiler drum level adjustment method

Abstract

The invention provides a method of adjusting the levelness of a coiling block of a coiling machine. A measurement fixture is included and comprises a circular hoop formed by two semicircular bending plates, wherein a support is arranged at the outer side of each bending plate; and a supporting rod parallel to the axis of the hoop is arranged on the support. The measurement method comprises the following steps of: manufacturing a sleeve, combining the sleeve and the coiling block in a tensioning manner, and installing an inside micrometer; inserting the coiling block into an external supportingpiece, and hanging a steel wire weight at the outer side of the extending end of the coiling block as a measurement data reference line; reading two reading numbers displayed when a measurement headof the inside micrometer rotates by 180 degrees, and obtaining an error value according to the formula; and finally comparing the error value obtained by calculation with a theoretical error interval,if the error value does not meet the requirements, finely adjusting the position of the coiling block in a horizontal direction by adjusting the positions of the two eccentric shaft sleeves, and thenrepeatedly checking till the error value is in the theoretical interval, ending working. The method improves the working efficiency by efficiently adjusting the levelness of the coiling block and isconvenient to operate.

Description

technical field [0001] The invention relates to the inspection and maintenance of a coiler, in particular to a method for adjusting the levelness of a drum of a coiler. Background technique [0002] The coiler is the main part of steel coil forming in the hot rolling production line, and the coil is the key to forming and also the main transmission system. Therefore, in order to reduce the overall vibration of the coiler after the coil is replaced, the horizontality of the coil and the The centering measurement and commissioning of the outer support has become the key control point of the coiler operation. [0003] The reel is composed of four major parts: outer chord shaft, wedge block, drum bearing, and spline shaft; the outer support is an important supporting component of the outer chord shaft of the reel, and the outer support is automatically assembled through two hydraulic cylinders in different directions during production onto the outer chord bearing (accessory 3)....

AI Technical Summary

Problems solved by technology

[0005] In the prior art, when a new reel is replaced, the levelness is measured on the reel according to the requirements. At this time, the data measured by the frame level meter changes, because the wedge block will change with the spring and its own weight, so the The levelness data detected by the frame-type spirit level and related measuring equipment is not true, and the adjustment is time-consuming and labor-intensive.
