Problems solved by technology

Affected by the shaping of the coil garden, it is generally difficult to meet the roundness of the drying cylinder at one time. It is necessary to add a support ring in the drying cylinder. Since the roundness deviation of the large drying cylinder is 20mm, the inner support ring cannot be placed in the drying cylinder at all. In the cylinder, it cannot be set up, even if there is a tolerance exceeding the standard after the set-up

Embodiment Construction

[0014] The present invention will be further described in detail below through specific embodiments.

[0015] Such as figure 1 As shown, a tooling is provided on the inner support ring of a drying cylinder, which includes a circular support 1, a plurality of nuts 3, and a screw 2 matched with the nuts 3. The support 1 includes a support formed by rolling a plate The main body 11 and the annular reinforcing ribs 12 welded to the upper end faces of the support body 11 can ensure that the strength of the support 1 meets the requirements. The several nuts 3 are evenly installed on the support 1 on the circumference, that is, the nuts 3 are welded to the body of the support 1, each screw 2 and the nut 3 are matched one by one, and the axis of each screw 2 passes through the support 1 The center of the circle, in this embodiment, the number of the screw 2 and the nut 3 is 24, and the angle between the screw 2 is 15°. The number of the screws 2 is not unique, that is, the number of the...

Abstract

The invention discloses a tool for an inner supporting ring of a drying cylinder. The tool comprises an annular supporting element, a plurality of nuts, and threaded rods matched with the nuts, wherein a plurality of nuts are peripherally and uniformly distributed on the supporting element. All the threaded rods are correspondingly matched with the nuts one by one. Axes of all the threaded rods all pass through the circle center of the supporting element. The tool can adjust the circular degree of the drying cylinder before the inner supporting ring is mounted, thereby guaranteeing that the circular degree of the drying cylinder meets the requirements, and the tooling operation of the inner supporting ring is convenient.

Description

Technical field [0001] The invention relates to a tooling for installing on top, in particular to a tool for installing on the inner support ring of a drying cylinder. Background technique [0002] The outer cylinder of the large jacket drying cylinder with a diameter of Ф2000 or more adopts carbon steel / stainless steel roll surface. The thickness of the roll surface metal is satisfied while the thickness deviation is within the allowable range (generally 2mm), and the static balance requirements must be met. Affected by the shaping of the roll circle, the roundness of the drying cylinder is generally difficult to meet the requirements at one time. It is necessary to add a supporting ring in the drying cylinder. Because the roundness deviation of the large drying cylinder is 20mm, the inner supporting ring cannot be put into the drying cylinder at all Inside the cylinder, it is impossible to install, even if the tolerance exceeds the standard after installation. Summary of the i...
