Description
Technical field
The present invention relates to one and semi-circular plate heat pressing and molding mold feeding supertension steel plate hydraulic press can either will carry out compression molding, have again lower table function concurrently, and the hot-forming steel plate hot-pressing forming system of steel plate that thickness can be reached more than 80 millimeters and forming method, belong to extraordinary truck and manufacture field.
Background technology
1, according to the development trend of self-elevating drilling platform in current world wide, the coming years operating water depth scope 400 feet, the jack-up unit of 500 feet will become main flow.From the point of view of spud leg semi-circular plate is processed, along with the raising of operating water depth causes semi-circular plate steel plate thickness to increase accordingly, but it is as the corresponding increase of ultra-high pressure hydraulic press tonnage, the structure that hydraulic press lower table moves integrally just seems heavy and involves great expense, the most how how the semi-circular plate steel plate of 900 ° of about C of high temperature is lifted on hot pressing die compacting, it has also become this area needs one of difficult problem of solving.
2, in current semi-circular plate processing industry, due to the restriction of hydraulic press equipment so that the semi-circular plate steel plate heated cannot directly be lifted on heat pressing and molding mold and suppress.Hot pressing semi-circular plate process whole process high-temperature operation, the danger that the tool that works under workmen's high temperature is certain, so that operating process is more complicated.Semi-circular plate steel plate heat is wasted in time and is run off, and needs to reheat insulation, affects quality, wastes resource, more cannot form batch production, reduces production efficiency.
Summary of the invention
Purpose of design: avoid the weak point in background technology, devise one and semi-circular plate heat pressing and molding mold feeding supertension steel plate hydraulic press can either will carry out compression molding, have again lower table function concurrently, can solve the problem that again that the operation in existing semi-circular plate hot pressing is complicated simultaneously, cost is too high, poor stability, the wasting of resources, the steel plate hot-pressing forming system of the problems such as production efficiency is low and forming method.
Design: the present invention it is critical only that solution work in hot environment during can automated handling material, in order to realize above-mentioned purpose of design, the present invention is on structure designs: 1, design mould upper bed-plate and the structure of mould lower bottom base combination, is one of the technical characteristic of the present invention.So purpose of design is: is not only suitable for truck and is moved into and out the working range of hydraulic press, mould can be fixed on mold base with integral installation simultaneously, and play the effect of hydraulic press lower table pressure-bearing, have rational in infrastructure, be beneficial to the feature of installation and removal.2, the design of the roll wheel assembly of band disc spring, be the present invention technical characteristic two.So purpose of design is: during pressing under hydraulic press cylinder, and disc spring stress bounces back, downforce by mould and base conducting pressure to lower table, common pressure-bearing；When, after hydraulic press cylinder release, disc spring is upheld, and makes mold base separate with hydraulic press lower table, produce gap, facilitate gear motor driven mold base and heat pressing and molding mold to move out hydraulic press working range, convenient handling material.3, the design of ejector beam, be the present invention technical characteristic four.So purpose of design is: due in the middle of turnover truck in four grooves equipped with ejector beam, after mold base moves out hydraulic press working range, by ejector beam, the semi-circular plate suppressed ejected heat pressing and molding mold, convenient handling material.4, the design of toothed gearing electric motor and spline-simulating guide rail engagement drive structure, be the present invention technical characteristic four.So purpose of design is: owing to two toothed gearing electric motors are relatively fixed the end plate casing both sides at movable mould base end face, and the gear in two toothed gearing electric motors is meshed with guide rail outboard rack, therefore movable mould base can be driven to move forward and backward under motor and decelerator drive, so that the working range that the heat pressing and molding mold being positioned on movable mould base can move super-high oil press quickly and easily carries out feeding, feeding can move to again in the working range of high hydraulic press quickly and easily after completing, thus reach energy-conservation, the purpose that hot pressing efficiency is high.
Technical scheme 1: a kind of steel plate hot-pressing forming system, including controller, the piston end surface intrinsic heat pressing die head of super high pressure oil press, the lower table of super high pressure oil press is respectively provided on two sides with many support posts, the upper surface of many support posts is covered with guide rail, guide rail is provided with movable mould base, it it is spline-simulating structure outside guide rail, two toothed gearing electric motors are relatively fixed the end plate casing both sides at movable mould base end face, gear in two toothed gearing electric motors is meshed with guide rail outboard rack and drives movable mould base to move forward and backward under motor and decelerator drive, steel plate heat pressing and molding mold is fixedly mounted on mold base.
Technical scheme 2: a kind of steel plate hot-press molding method, when steel plate needs hot-forming, controller instructs two toothed gearing electric motor synchronous workings and moves to outside super high pressure oil press hot pressing die head by movable mould base along guide rail, now the high temperature steel plate after heating is hung on steel plate heat pressing and molding mold by loop wheel machine, controller instructs two gear motor synchronous workings and movable mould base pushes the lower section of ultra-high pressure hydraulic press hot pressing die head, then while instruction ultra-high pressure hydraulic press drives the steel plate press-in steel plate heat pressing and molding mold that hot pressing die head lower compression makes to be positioned on steel plate heat pressing and molding mold, it is positioned at many sets roll wheel assembly of mould upper bed-plate both sides when pressing under ultrahigh-pressure hydraulic Oil cylinder, mold base reduces with lower table gap, play pressure-bearing effect；After ultrahigh-pressure hydraulic Oil cylinder release, disc spring in roll wheel assembly makes movable mould base produce gap with lower table, facilitating toothed gearing electric motor drive mold base and be positioned at heat pressing and molding mold on movable mould base and move out hydraulic press working range, the ejector beam being positioned in mold base groove rises under the effect of its underpart hydraulic jack and the product after molding is ejected heat pressing and molding mold.
The present invention is compared with background technology, and one is the design of the upper and lower base of mould, it is possible to installs fixing heat pressing and molding mold and hydraulic press lower table, forms a set of overall structure, makes a whole set of input and output material bassinet structure tightr, more practical, mounts and dismounts easier simultaneously；Two is the design of roll wheel assembly and ejector beam, gear motor driven mold base and heat pressing and molding mold is facilitated to move out hydraulic press working range, ejector beam ejects the semi-circular plate suppressed, convenient handling material, achieve the convenient, flexible of high temperature handling material, the most in hgher efficiency, and guarantee workmen's safety, it is often more important that achieve the application on large hydraulic press of the automatic feed/discharge car.
