1000-series Entry Roller Guide

SR/DR

The 1000-series is Morgårdshammar´s latest developed series of roller guides for guiding of various sections. It has been developed with the experience from the very successful and well known 900-series.

The series is available as Single pair Roller guide, SR, and Double pair Roller guide, DR.

The 1000-series feature an identical patented central setting arrangement as the 900-series guides. Which means that the guides are equipped with a single point adjustment for setting the distance between the rollers for both SR and DR versions. The development on the setting device compared to the 900-series is that the cam is operated by means of a worm gear. The arrangement guaranteeing an absolute accurate setting of the guide rollers and in addition is it self-locking. The design also allows the possibility to adapt a remote control device.

The guide line during the development of the Morgårdshammar 1000-series guides have been Strength & Precision which have resulted in a overall upgrading in respect of material quality, tolerances and bearing sizes. This will result in a high accuracy guiding of the rolled product with the benefit of a high quality end product for our customers.

The single point regulation system allows the 1000-series guide to be equipped with a remote control system without any special changes of the guide. The guide regulation is operated by a motor, of any kind, equipped with an encoder via a flexible shaft, as seen on the picture to the right.

The 1000-series are available in several different sizes both as SR and DR type. The design is how-ever made in order to minimise the number of standardised parts to give the advantage of low inventory for our customers. As example is the entry guide halves, rollers and inner roller holder common for both SR and DR type of guide of the same size. Also worm gear regulation system is common for close sizes.

Morgårdshammar can supply some of the presen-ted guides in versions with wider body, recognis-ed by an additional letter added to its name, ”B” ”C” etc. Please contact us for further details.

The 1000-series guides are designed with single point symmetrical dis-tance adjustment for quick, precise and reliable setting of the guide. The single point adjustment allows

parallel setting of all four rollers on a DR-type guide. Possibility to individual setting of roller vertical position.

The setting is carried out by means of a standard wrench.

For arrangements where a DR-type of guide and short distance between guide roller and mill roll

is crucial have Morgårdshammar developed the P-version guide. The roller arrangement of the front pair of rollers is taken from the closest smaller type of guide. The table later shows the guide

with wider body, ”B”, but can be supplied in any version as a standard DR-type of guide.

In order for Morgårdshammar to provide our customers with the correct guide selection and proposal for mountings we kindly recommend our customers to fill in the ”General Inquiry Sheets” in the end of this brochure. You are of course also welcome to contact our offices or representatives around the world and we will be pleased to assist you.

Mounting of 1000-series Roller Guides

The 1000-series guides can be easily mounted into the mill stand on base as well as into a cas-sette. Both alternatives can be designed as fixed or with fine pass adjustment for accurate setting against the pass line. The bases and cassettes can be provided as single or multiple strand type and in that way cover all poss-ible needs. The cassette mounting is preferable when quick change of the guide equipment is required.

Precise setting of precise guides calls for pre-cise setting tools. An accurate setting of a roller guide is very important. Morgårdshammar have developed and can provide the correct setting tools for all different needs and requirements.

Setting tools for 1000-series Roller GuidesIt is highly recommended to use our optical set-ting device. There are two optical setting devices available. For larger sections or were the require-ments are not as high a mechanical system may be sufficient enough.

The optical setting system, as shown, where the image of the rollers are projected, with magnifica-tion, on a template to compare the setting to the theoretical correct groove. The other optical system, the Hi-Line®, uses a camera and computer program instead of the template. The Hi-Line® optical system is a product provided in cooperation with Danieli Automation.
