Description
Technical field
The utility model relates to engineering pressure pipe manufacturer technical field, especially a kind of square tube mould being wound around square container for the manufacture of polyethylene.
Background technology
At present for storing or transport specialized fluids on market, as comprised the organic of all corroding metals or electrodeless solution etc., its load container is anticorrosion container in steel, volume is larger, when anticorrosive coat suffers that destruction fails again to detect in time, store these corrosive solutions and there is very large potential safety hazard, once metal level is corroded, liquid can be leaked by corrosion place, causes security incident.Select the square container that a kind of polyethylene winding process method obtains, because take-up strap alternately suppresses welding, interior anticorrosive coat is made to have high density, have the features such as high adhesion with steel body, this bore is large, length reaches the large gauge container products generally surpassing 5 meters and adopts general processing method or mould to be difficult to reach technical quality requirement, need a kind of special square tube mould, this mould need container formation after fast demoulding.
Summary of the invention
The purpose of this utility model is the formation problems manufacturing anticorrosion container in large gauge in order to solve polyethylene canoe, provides a kind of reasonable in design, built-in flexible frame, mold integral is quantitatively shunk, reach the square tube mould of fast demoulding.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of square tube mould being wound around square container for the manufacture of polyethylene, comprise the steel cylinder equal with square container hole size, the expansion bracket be built in steel cylinder, it is characterized in that described expansion bracket comprises the drive unit being positioned at expansion bracket length direction middle part, drive some rows along expansion bracket length direction screw lift structure arranged in parallel by drive unit, screw lift structure connects some portable plates; Described steel cylinder is divided into some identical with portable plate quantity, and links into an integrated entity with portable plate joined together.Cross section is square or non-circular large-volume receptacle because length is longer, and the adhesion strength of interior anticorrosive coat requires very high, need enough outer bulging power, and as a product, the fineness of inner surface also has higher requirements.The mode that the technical program adopts multiple screw lift structure to arrange along its length carries out synchronization telescope operation to whole expansion bracket, completes the demoulding after the compression to anticorrosive coat in container, sizing.Steel cylinder presses the hole size design of standardized product, and split after integral manufacturing, to ensure size of main body requirement, each elevating mechanism is all linked with one another, compact conformation.
As preferably, described every part screw lift structure all be located on steel cylinder inwall and the portable plate be arranged in parallel and be connected, all screw lift structure synchronization actions.Steel cylinder after segmentation is fixed by each portable plate along its length, a common formation mold integral.
As preferably, described portable plate comprises the U-board being positioned at bottom, and be positioned at U-board both sides and the side plate hinged with it, the top of biside plate is connected with top board respectively by connecting rod, and the lower end of top board is connected with screw lift structure.Because volume, weight are all comparatively large, the stability requirement of whole mould is also high, adopts U-board as the lower support of expansion bracket, ensures stability during die operation.And biside plate as while contraction movement internal mold, avoid causing damage to product endoporus.
As preferably, described top board is inverted isosceles triangle, one end of leg-of-mutton two base angle ends hinged two connecting rods respectively, the other end hinged side of connecting rod.Screw lift structure, top board, connecting rod form expansion bracket jointly.In this device, all top boards, side plate, U-board all link into an integrated entity with major axis.
As preferably, described expansion bracket both ends of the surface are respectively equipped with roller, and the diameter of roller is less than the interior empty size of steel cylinder.During operation, the whole mould of pair of rollers, as the use of support, completes charging, the demoulding.
As preferably, described drive unit is fixed by lower pedestal, and described lower pedestal is connected with U-board.Lower pedestal is the basis of expansion bracket, and this programme demoulding U-board is not done as base plate and shunk.
As preferably, described roller and lower pedestal are connected and fixed, and the bottom position in roller is equipped with suspension rod.The stroke that screw lift structure, top board, side plate produce is positioned at the outside of roller, and suspension rod is for transporting die-filling tool.
As preferably, described drive unit packaging reductor, speed reducer output shaft two ends are connected with the driving wheel in adjacent two screw lift structures respectively by universal joint.Because the length of this device is longer, carry out unlatching to the steel cylinder in whole die length direction simultaneously and shrink, need larger power, drive unit is positioned in the middle part of steel cylinder, and then power transmission shaft extends to two, and to reach uniform force application, power attenuation is few.
As preferably, the live axle of described screw lift structure is double-headed shaft, and double end one end coordinates with universal joint, and the double-headed shaft other end is connected with next universal joint by axle sleeve, connecting axle.The drive unit of the technical program adopts multi-link axle, multiple shaft sleeves, becomes to coordinate transmission one by one to joint, easily processing, easy assembling, easy care more.
Effective effect of the present utility model is: the screw lift structure along container length to distribution, makes built-in flexible frame synchronization telescope, location and the demoulding in product endoporus fast; And the steel cylinder with smooth outer surface ensure that the interior anticorrosive coat of container products and product steel body are fully adhered, avoid again producing inner surface flaw.Simple to operate, practical.
