Abstract
Description
- This invention concerns a complete modular rolling stand. To be more exact, the invention concerns a rolling stand already pre-arranged in the manufacturer's factory for installation and immediate functioning without the normal operations of assembly, setting up, testing, etc.
- Rolling stands may have their rolls supported at both ends or supported as a cantilever and the axes of the rolls may be horizontal, vertical or inclined.
- The rolling stands having their rolls supported at both ends may be of any type such as stands with housings, cartridge-type stands, pre-stressed stands, etc.
- The present invention therefore means by the words "rolling stand" any type of rolling stand which comprises rolls supported at both ends or supported as a cantilever.
- The known art provides for rolling stands, even those having rolls supported as a cantilever, to cooperate on a base which comprises civil works such as conduits, discharge channels, hydraulic works prepared for individual tasks, etc., the whole having the purpose of supplying the rolling stand itself.
- In the known art the rolling stands are anchored to the ground, which has already been prepared with all the necessary civil works.
- After the stand has been anchored to the ground, connections are made to the civil works, whether of an electrical, or hydraulic type, etc., or to coordinating and linking works.
- This entails a great waste of money and time since the execution of such works causes reciprocal interference between the various persons thus employed and requires considerable space and successive intermediate times for timing and testing the machine; it also necessitates great care in checking and testing the works themselves and also the rolling machine when installed.
- Moreover, the problems of procurement and delivery in themselves are considerable.
- Document GB-A-1,049,763 discloses a rolling stand which is mounted on a frame, said frame being fixed to a base which is detachably secured to foundation skids. Said base is not provided with any means for supporting the motor for driving the rolls, or for supporting a control panel. The stand is also not provided with feeder and service conduits located in predetermined areas of the base.
- The present applicant desired to eliminate all the above drawbacks and at the same time to embody a rolling stand which offers many advantages and which provides manifold benefits and usefulness for the end-user of the stand and for its manufacturer.
- This is achieved by a modular rolling stand having the features disclosed in claim 1.
- The dependent claims outline preferred forms of embodiment of the invention.
- By means of the invention the rolling stand leaving its manufacturer has already been tested and perfected in every detail and component, so that for its installation it is enough to fix its base to the ground and to connect the stand to its supply means as already arranged; the machine has already been tested and is operational at the time when the final connection is made.
- The stand according to the invention entails also the advantage that it possesses standard dimensions and can therefore be readily combined with other stands or other machines without creating problems of disturbance of the layout or foundations, such problems not being easy to foresee in the case of traditional machines.
- According to a preferred form of embodiment of the invention the rolling stand comprises a soundproofed room which holds the motor. Such room is equipped with means to cool the environment and contains the electrical control and operating panel.
- According to the invention the stand includes a base containing zones individually equipped for the positioning and passage of the various feed and service units, whether these be for the water, hydraulic or electrical supplies, etc.
- The various supply and service units are equipped at their ends with means to obtain a speedy and firm connection to the stand or to the preceding or subsequent usage means.
- A motor and the stand itself are positioned on the base, while a channel to discharge slag is included in direct cooperation with the stand.
- The stand in itself is already provided with shields, means to actuate the shields and other equipment.
- According to the invention the machine is completely finished in every detail in the supplying factory, where it is fitted with means to cool the rolls, connections required for the means to cool the motor, brackets for hydraulic clamping and every other necessary component.
- Moreover, possible sprayer nozzles cooperating with the channel for discharge of slag and every other electrical and hydraulic service means are pre-assembled in the supplying factory.
- All the various parts which constitute a finished stand ready to work are previously connected and tested during preparation of the stand, so that such parts do not have to be checked or connected when the stand is installed on its usage site. Transport operations too are simplified.
- The attached figures, which are given as a non- restrictive example, give a diagrammatic idea of the embodiment as follows:-
- Fig.1 shows a lengthwise section of a rolling stand with rolls supported as cantilevers;
- Fig.2 gives a side view of the stand of Fig.1;
- Fig.3 shows a stand with rolls supported at both ends.
- The drawings and description cover both a stand having horizontal rolls supported as cantilevers and a stand having rolls supported at both ends in housings.
- According to the invention a
stand 10 connected to amotor 11 is located on abase 37, which in this example comprises levellingfeet 16 solidly fixed to abase plate 17. - The
base 37 may include plates for lateral connection to other modular units. - The levelling
feet 16 are positioned crosswise to the lengthwise vertical plane of the machine. - A
soundproofed room 19 cooperates with themotor 11 and comprises adoor 20 for access to the room and also at least onewindow 38. - An
airconditioner unit 39 or at least a means to cool the environment is located in theroom 19 to keep the inside of the room at the required temperature. - Means to detect fumes or fire and possible extinguishers may also be provided.
- An
electrical control panel 22 is comprised inside thesoundproofed room 19 and will be complete with all the actuation means and controls required for the proper and complete functioning of the rolling stand, equipment and every other connected element. - The
electrical control panel 22 is connected to themotor 11 through aconnection box 25 and is fed from the exterior supply through afeed box 23. - The
feed box 23 comprises means for speedy connection to the supply sources or other external utilities and to other units positioned alongside the stand. - A series of
electrical conduits 24 passes transversely through the base of the Stand and provides the electrical connections to make possible the passage and supply of power, services and controls. - The
electrical conduits 24 are already connected to thefeed boxes 23 and thereby to theelectrical control panel 22 and utilities. - Connection to the exterior takes place normally by a butt connection through the
feed boxes 223 but may also take place through thefeed boxes 23. - At the ends of the
electrical conduits 24, therefore, suitable means are included for connection to analogous conduits included in stands located upstream and downstream, or to supply, service and control means located upstream, or to other usage means located downstream. - The
electrical conduits 24 serve to convey motive power, generally electrical power, and also the electrical controls and links. - A
means 21 to cool themotor 11 is also comprised in thesoundproofed room 19 and is connected directly to a coolingwater inflow pipe 27 and to a waterreturn flow pipe 30. - The cooling
water inflow pipe 27 supplies water at the required pressure, whereas thereturn flow pipe 30 acts as a drain for water used either within the cooler means 21 or in theairconditioner 39 or in other possible usage means. - The rolling
stand 10 of Figs.1 and 2 is equipped withrolls 12 supported as a cantilever, which in this case have ahorizontal rolling axis 13 and comprise already installed brackets for hydraulic clamping and balancing as required to withstand and annul the weights acting on the shafts of therolls 12. - The
rolling stand 110 of Fig.3 is provided withrolls 112 supported at both their ends and withrolling shafts 113 and is already directly equipped with the necessary equipment and usage devices. - Cooling units 36-136 which are fed with water under pressure by a
pipe 29 are included in cooperation with rolls supported ascantilevers 12 or supported at bothends 112. -
Such pipe 29 feeds also spraynozzles 35 which scour and clean aslag discharge channel 18.Such discharge channel 18 for slag is comprised in the base of the stand and runs crosswise to the stand, being positioned in cooperation withrolls 12 supported as a cantilever or withrolls 112 supported at both ends. - The
rolls 12 supported as a cantilever and possibly at least part of therolls 112 supported at both ends are protected by a shield 14-114 which can be lifted by ajack 15 to permit ready access. - In the case of a
stand 110 havingrolls 112 supported at both ends the zone ofroll extensions 40 and possibly also agear box 41 may be protected by ashield 214. - The
extensions 40 and housings of the stand of Fig.3 are obviously complete with all the equipment required to support the extensions and to replace therolls 112. - One or more
reserved conduits 28 may be provided in thebase 37, which will also include one or more conduits for lubricatingoil 26, conduits forgrease 31, conduits for oil underpressure 32, conduits foroleodynamic drive units 33 andpossible reserve conduits 34. - Further conduits may be provided for other functions such as compressed air, an inert gas, etc.
- All such conduits positioned crosswise to the
base 37, whether they be electrical, hydraulic or oleodynamic, include suitable terminal connections able to connect them to coordinated supply conduits positioned upstream or to further usage means or to conduits located downstream of the stand itself. - The channel for discharge of
slag 18 too comprises suitable means for connection to analogous channels or coordinated discharge means located upstream or downstream ofsuch discharge channel 18. - Each zone of the stand is therefore prepared for individual tasks and finalized functions and includes the operational means and necessary auxiliary means as well as possible means for connections upstream and downstream.
- It is to be understood that the
stand 110 of Fig.3 comprises also thegear box 41 andextensions 40. - The stand according to the invention is therefore perfectly finished and tested as regards all its parts when despatched from the manufacturer's factory, and this situation provides both its producer and the end-user with a great number of advantages and great usefulness.
- A first advantage lies in the fact that all the civil works forming part of the machine are already positioned and set up in the machine without any need to be arranged.
- A further advantage is the fact that all the parts of the stand are finished and ready, thus reducing sharply the times involved and the problems of despatch, storage, assembly and timing of start-up of the machine itself.
- If such stands have to be stopped for replacement or innovation of equipment, this embodiment requires very short times for such replacement work.
- Moreover, the approval trial of the stand on its installation site becomes unnecessary to the extent hitherto known since such trial has already been performed when the stand was being prepared in the factory.
