Abstract
The present invention relates to for the mould on winding-type bell and spigot joint former, comprise die ontology and the mould holding portion of integral type design, described die ontology external diameter is fixed, mould holding portion outer radius variable, die ontology comprises the base and the dividing plate that are oppositely arranged, between base and dividing plate, be provided with closed-loop, closed-loop is connected the outer of base and dividing plate. The present invention is applicable to the production of winding pipe.
Description
Technical field
The present invention relates to winding pipe production technical field, refer to especially for winding-type bell and spigot joint moulding and establishStandby upper mould.
Background technology
The material difference that existing helically-wound shaped plastic tube uses when Wrapping formed, can be divided into hollow wallWinding pipe, carat pipe, reinforced steel-band winding pipe, internal-rib strengthen the concrete product such as winding pipe, plastic-steel spirally-wound pipeProduct form. Because it has higher high ring rigidity, be widely used in the occasion such as draining, low pressure water supply. PipelineConnected mode mainly contain electric smelting band connect, thermal shrinkable sleeve connect, electric smelting socket joint connect, socket joint sealing ring connect,The various ways such as clamp connection. This wherein, electric smelting band connects and is connected with thermoplastic cover because cost is compared with low arriving extensivelyGeneral application, but higher to construction environment and technology, and construction quality is because of the situation difference of each construction teamCan not get ensureing, be relatively applicable to the connection of small-bore pipeline. High and the connection side of clamp connection mode cost compareFormula reliability is poor. Socket joint connects and comprises electric smelting socket joint and sealing ring socket joint, the former of bell and spigot jointMainly contain two kinds of injection molding and winding-types, injection molding former is exactly by injection machine and mould, by jointIn the injection mo(u)lding of tubing two, equipment increases along with the increase of caliber, and therefore, injection mo(u)lding joint is currentOnly be applied to small-bore pipeline, and price is higher. Filament winding process is similar to the mode of tube forming, willPlastic strip is wrapped in tubing two, is bell and spigot by mould molding.
At present, conventional mould is divided into two classes, and a class is taper fixed mould, utilizes taper to increase graduallyDiameter is fixed tubing, but because the caliber of the tubing of specification of the same race exists error, makes tubing solid on mouldFixed change in location is larger, and the bell and spigot of last moulding also just exists and larger error; Another kind of is external diameterVariable mould, it has telescopic shell for fixing tubing, but due to the pipe of the tubing of specification of the same raceThere is error in footpath, causes the external diameter of mould to change greatly, makes the bell and spigot of last moulding also have larger mistakePoor.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of variable external diameter for winding-type bell and spigot jointMould on former, this mould stability is higher, and result of use is better, and error is less, and leadsHot coefficient is lower, can solve and when plastic strip is wound on mould, sharply shrinks and affect the smooth of goods inwallThe problem of degree.
For solving the problems of the technologies described above, the technical solution used in the present invention is: become for winding-type bell and spigot jointMould on type equipment, comprises die ontology and mould holding portion that integral type designs, outside described die ontologyFootpath is fixed, mould holding portion outer radius variable, die ontology comprises the base and the dividing plate that are oppositely arranged, base andBetween dividing plate, be provided with closed-loop, closed-loop is connected the outer of base and dividing plate.
As a kind of preferred version, described closed-loop outer wall adopts nonmetallic materials to make.
As a kind of preferred version, described mould holding portion is arranged on the front end of base, and base front end face arrangesHave the central shaft perpendicular to base, central shaft front end is provided with top board, and central shaft external activity is arranged with activityRing, is evenly provided with at least two track plates on loose collar outer wall, track plates is perpendicular to loose collar outer wall, railThe rear end of guidance tape is connected by connecting plate, is provided with the rail tilting from inside to outside from track plates rear end on track platesRoad groove, connecting plate rear end face is connected with at least three front push rods, and front push rod is movably arranged in die ontology alsoThrough die ontology, on described dividing plate, be provided with through hole, front push rod is movably arranged in through hole, dividing plate rear endBe provided with pushing block, be provided with the rear push-rod corresponding with lead to the hole site on pushing block, the diameter of section of rear push-rod is largeIn the diameter of section of front push rod, rear push-rod front end is connected with front putting back-end, on front push rod, is provided with resetSpring, the two ends of back-moving spring are inconsistent with the front end face of base rear end face and rear push-rod respectively, described trackIn groove, be movably set with the slide block matching with rail groove, slide block two ends are respectively arranged with back-up block, back-up blockBe connected by the gripper shoe that is parallel to central shaft, gripper shoe outer wall is provided with clamping part housing, clamping part shellBody annular arranges, and between adjacent two clamping part housings, is provided with equidistant gap.
As a kind of preferred version, described gripper shoe rear and front end is respectively arranged with boss, boss respectively with topThe rear end face of plate and the front end face of base are inconsistent.
As a kind of preferred version, described clamping part housing is circular arc type, and clamping part housing front end exceedes bossThe part of front end face is intilted inclined-plane.
As a kind of preferred version, described track plates is provided with four.
As a kind of preferred version, described front push rod is provided with four.
The invention has the beneficial effects as follows: above-mentioned mould due to be provided with fixed outer diameter die ontology and variable outsideThe mould holding portion in footpath, can adapt to the pipe fitting of different bores, and because the external diameter of die ontology is constant,Make the bell and spigot bore of final molding constant, error is less, and stability is higher, again because closed-loop adoptsNonmetallic materials are made, and thermal conductivity factor is lower, can prevent from sharply shrinking when plastic strip is wound on mould andAffect the smooth degree of goods inwall, save the link to die surface heating.
