Description
Technical field
The present invention relates to steel sheet material automatic forming processing equipment, particularly relate to the automatic forming processing equipment of steel sheet material in the industries such as shipbuilding, aviation, boiler, chemical industry, automobile making.
Background technology
The processing of steel sheet material sheet forming is the bottleneck of production procedure in the industries such as shipbuilding, aviation, boiler, chemical industry, automobile making always, thereby causes concern.
With shipbuilding industry is example, because sheet material is processed the difference of desired curvature complexity, used processing method is also different, and main mode has the curved and sheet material clod wash of sheet material fire.Wherein curved, press-bending etc. is rolled in the sheet material clod wash again.
Along with the development of shipbuilding technology and the develop rapidly of shipbuilding industry, the shipbuilding progress is accelerated in an urgent demand, realize automation as early as possible, and it is minimum that complex-curved sheet material is processed just in the shipbuilding industry automaticity, so domestic research to flame forming plate at present is more, mainly contain Shanghai Communications University and Dalian University of Technology, but also do not obtain remarkable progress, realize that the automation practical application of flame forming plate also has a segment distance.Research to flame forming plate mainly concentrates on the following aspects:
(1) the moulding factor analysis during flame forming plate is set up the database of sheet material temperature distortion, and is started with thus and study flame forming plate machine people, replaces present pure manual operations with this.
(2) the sheet material Study on Mathematic Model of curved surface of being heated is represented the curved surface of complexity, and then is studied the numerical control water-fire heating plate bending machine with mathematical equation, realizes the automation of flame forming plate.
Sheet material cold working is still adopted the sample method for processing so add at present because problems such as deformation resilience do not solve preferably man-hour, and realization bent plate technical process is controlled automatically, is the inexorable trend of hull plate shaping process automation.Domesticly mainly concentrate at present the research that sheet material rolls curved processing, actual what use also mainly is three-roll bending machine and drop into, and also has four-roll bending machine in addition, and the shortcoming that their exist mainly is can only crooked single panel, can not the processed complex curved surface.What carry out this respect research mainly is Wuhan University of Technology and some shipyards.Research mainly concentrates on two aspects:
(1) to having the corrective measure of bending roll machine now.Mainly be the relation of research roller lifting value and sheet bending value, set up automatic control model and use finite element to analyze sheet material bending machine reason.
(2) intellectuality is combined with squeezer, introduce the neuron fuzzy control theory, realize that with this sheet material processes automatically.
What come into operation at present mainly is three-roll bending machine, uses hydraulic-driven.A Japan day field company (Amada) has developed a kind of speed recently near 200mm/s, and model is the high speed squeezer of HDSn8025NT, and this machine adopts the AC driven by servomotor, can carry out the mixed type kind of drive that oil mass is adjusted.
Summary of the invention
The objective of the invention is: a kind of plate forming mill of being convenient to numerical control is provided, can replaces artificial extreme misery and the bending making of colding pressing, realize that steel sheet material is processed into the snyed plate process automation.
The object of the present invention is achieved like this:
It is a kind of fixing cantilevered three fulcrum hydraulic pressure plate forming mills (wherein three fulcrums roll bending apparatus can turn round in the 90 ° of scopes in XY plane).Three point working element and the synchronous revolving body of electronics and cantilevered fuselage and the support that comprise rolling.
Three point working element are made up of a pair of upper and lower roller.Upper roller is the driven pulley that has telescopic hydraulic cylinder, but oscilaltion forms the point of application (in three fulcrums a bit) to workpiece; Bottom roller is by the driving wheel of hydraulic motor through deceleration transmission, and its U type groove is the counterdie that constitutes two fulcrum supporting steel plates.Steel plate is subjected to roll extrusion between the bottom roller of the upper roller of convex and spill.The synchronous revolving body of electronics divides two parts up and down, and last revolving body is contained under the cantilever of cantilevered fuselage, realizes the driven pulley revolution of band telescopic hydraulic cylinder; Turning next time is contained on the support, realizes that driving wheel and driven pulley electronics turn round synchronously.
Upper roller is connected to the piston lower beam of hydraulic jack by its support 1, and the piston upper boom is equipped with the revolution driven gear, is driven by rotary motor by connecting rod with the revolution driving gear of its pairing, and they constitute together goes up revolving body.Last revolving body is contained on the cantilevered fuselage, and the angle of revolution is detected by the angular transducer that is installed on the gyroaxis.
Bottom roller supports by bearing block, and bearing block is installed on the band external tooth pivoting support, and it is by the fluid motor-driven revolution of band gear pair, and the angle of revolution is detected by the angular transducer that is installed on the gyroaxis.Turning next time that they constitute is contained on the support.Bottom roller is connected with hydraulic motor by spline, rolls curved driving wheel as sheet material.
Plate is carried between upper roller and the bottom roller, the hydraulic coupling of plate through applying, and it is curved to finish rolling of steel plate under driving wheel (bottom roller) drives.
Advantage of the present invention: can directly bend the plate of unidirectional curvature and complicated curvature, also be fit to processing sector outside plate, good forming effect, the working (machining) efficiency height pollutes little.The roll forming of colding pressing is compared with the line heating means, factor affecting such as no heating mode and parameter, the type of cooling and parameter, and forming technology is simple; Cold pressing and roll the curved contactless detection of curved relative extreme misery, environmental condition will be got well, and non smoke is to the influence of sensor, and automatic moulding is realized easily.
