Abstract
Problem existing for current more roller rolling machines, during rolling machining, can usually run into the cylinder rolled out and the small situation in two broad in the middle occurs, our usual this phenomenons are referred to as barrel distortion.The generation of deformation brings great inconvenience to welding or mounted inside, if deformation is too big, it is necessary to by that could meet the requirement to process below to workpiece progress shaping.Barrel distortion is thicker mainly due to the upper roller of veneer reeling machine, and preferably, lower roll is slightly thin for rigidity, and rigidity is not so good as upper roller.The present invention proposes that upper roller, left roller, right roller use round roller, and lower roll uses oval roller.One end of lower roll is connected by shaft coupling with indexing means, can rotate lower roll and web contact bus according to the hardness of roll bending material.Larger to reaction force caused by lower roll when sheet material hardness is higher, rotatable lower roll makes the major axis bus and web contact of oval cross section, reduces the amount of deflection of lower roll.Indexing rotary table is divided into six stations, when roll bending material hardness is relatively low, ellipse short shaft bus and web contact can be used, so as to expand the processing range of four-roll plate bending machine.
Description
Technical field
The present invention designs a kind of veneer reeling machine, particularly a kind of four-roll plate bending machine that lower roll can be adjusted according to different plates.
Background technology
In our daily life, various cylinders, circular cone and arc-shaped plate are seen everywhere, and steel factory steel dispatch from the factory and are
All it is sheet material, therefore just needs us to carry out the plastic deformations such as mechanical bending, curling by the sheet material to correlation, and is machined
In used veneer reeling machine just can meet related requirement, reach the crimp radius of correlation.
As the progress of Numeric Control Technology, computer technology and automatic technology is with ripe, various machining equipments are
Develop to high efficiency, high accuracy, automation, intelligentized FMC direction, the overall development trend of veneer reeling machine is also just
To highly intelligentized FMC development.As shipbuilding, mechanical processing industry are to large-scale, ultra-large type, highly intensive
Direction is developed, for slab, special heavy plate, composite board, special type sheet material the demand of processing equipment can be increasing.It is new
Processing method then need veneer reeling machine using Numeric Control Technology as core, to it is quick, it is set of automation, intelligentized Flexible Manufacture list
Member development, to adapt to the different process requirements of people.The main dynamic device of veneer reeling machine（Predominantly motor）, transmission device
（Various shaftings, decelerator, worm and gear, guide rail etc.）The control system of frame, base and correlation is formed.According to criteria for classification
Difference, there is miscellaneous veneer reeling machine.Problem existing for current more roller rolling machines, during rolling machining, usually
The cylinder rolled out can be run into the small situation in two broad in the middle occurs, our usual this phenomenons are referred to as barrel distortion.Deformation
Generation to welding or mounted inside bring great inconvenience, if deformation it is too big, it is necessary to by workpiece carry out shaping could expire
Requirement of the foot to process below.But the shaping of this kind deformation is extremely difficult.In general, the upper roller of veneer reeling machine is thicker, just
Property it is preferable, lower roll is slightly thin, rigidity be not so good as upper roller.If the lower pressure of upper roller is too big during roll bending, and when the rigidity for surveying roller is insufficient, just
Roller bearing can be made to deform and bend during cylinder is rolled.The reason for producing barrel distortion is mainly due to roll shaft
Rigidity deficiency and deform so that in the same aspect of sheet material caused by sliding roll shaft length direction each point unbalance stress.For volume
Make preferable cylinder and remain that the gap uniformity between upper and lower roll shaft is consistent, ensure its thrust and bending to sheet material
Identical power is very important.Corresponding measure rice should be just taken to prevent that roll shaft from deforming or roll shaft produces to reach this purpose
Raw deformation is made up and eliminated.In light of the circumstances.Following measures can be taken respectively：First, the veneer reeling machine chosen it is each
Roll shaft will have enough rigidity, and each roll shaft is also not to deform when the plate of maximum specification is rolled.But roll shaft
Rigidity be that the related to its section modulus is limited by device structure and other factorses.Roll shaft can not possibly be made to especially thick,
In the case, recommendation device manufacturing firm is answered according to different parameters such as the performance of the length of veneer reeling machine and roll bending material, thicknesss of slab,
Considering each roll shaft being designed to slightly arc (being only applicable to certain sheet metal thickness scope), i.e. roll shaft carries out arc amendment,
Purpose be exactly in order to during roll bending after there is deflection deformation in up-down rollers stress its clamp sheet material part flatten out substantially
Directly.Ensure that the gap between the up-down rollers of clamping sheet material is consistent.Make sheet material along roll shaft length direction each point uniform force arc chis
Very little size should be careful by veteran professional and technical personnel progress according to the parameter such as material and applicable sheet thickness scope
Calculating.Second, the lower roll middle part for the veneer reeling machine chosen should carry Auxiliary support roller to strengthen the rigidity of lower roll, aid in
The quantity of back-up roller wheel is set according to device length；Or both the amendment of roll shaft arc and Auxiliary support earth wheel have both at the same time.
The content of the invention
The present invention be a kind of adjustable four-roll plate bending machine is provided, be not only simple in structure and according to different processing
It is required that and sheet metal thickness, adjust lower roll station, reached the rigidity to lower roll, so as to reduce barrel distortion.
A kind of adjustable four-roll plate bending machine of the present invention, including upper roller, lower roll, left roller, right roller totally four rollers,
Decelerator, shaft coupling and upper roller are passed through by main motor（Drive roll）It is connected, moment of torsion is provided for roll bending motion；Lower roll passes through
Hydraulic oil in Hydraulic Power Transmission System in hydraulic cylinder acts on piston and carries out vertical displacement movement, and upper roller coordinates for clamping
Sheet material；There is two side rollers that banking motion is done along rack rail lower roll both sides simultaneously, reduce rotating speed by single reduction gear, lead to
Cross leading screw, screw and worm gear, worm screw（Collectively constitute screw-nut Worm Wheel System pair）Change its transmission direction.Upper roller,
Left roller, right roller use round roller, and lower roll uses oval roller.One end of lower roll is connected by shaft coupling with indexing means, can root
According to the hardness of roll bending material, rotation lower roll and web contact bus.When sheet material hardness is higher, to reaction force caused by lower roll
Larger, rotatable lower roll makes the major axis bus and web contact of oval cross section, reduces the amount of deflection of lower roll.Indexing rotary table is divided into six
Station, when roll bending material hardness is relatively low, ellipse short shaft bus and web contact can be used, so as to expand four-roll plate bending machine
Processing range.
