Description
Technical field
The present invention relates to a kind of frock, the specially processing tool of magnetic drive pump isolation cover.
Background technology
An isolation cover processing always difficult problem, because the material that isolation cover is adopted is fluoroplastics, and the most frequently used fluorine is moulded
Material has：Polyvinylidene fluoride（PVDF）And perfluoroethylene-propylene（F46）Two kinds, shaping process of pressure injection can be met, but molding
Excircle of workpiece wall thickness typically only 3 ~ 4mm afterwards, on lathe, direct clamping is easily deformed it is impossible to meet general turnery processing.
Using disposable Shooting Technique, not only it is not required to after molding be processed again, and yield is also high very than injection-compression molding
Many, it is constantly subjected to the favor of producer, but Shooting Technique can only use polyvinylidene fluoride（PVDF）Material, perfluoroethylene-propylene
（F46）Not all right, that is because that it is serious to the Screw Corrosion of injection machine, and most absolutely producer is reluctant to take chances and does, so
Magnetic drive pump is just limited by material in the choice, is needing to use perfluoroethylene-propylene（F46）The isolation cover of material just cannot
Meet.
Content of the invention
The purpose of the present invention be exactly for isolation cover injection-compression molding after, the situation of turnery processing can be carried out on lathe.
Concrete technical scheme is：
The processing tool of magnetic drive pump isolation cover, including Internal hole positioning mould；Described Internal hole positioning mould includes annular flaring tabletting, cover
Cylinder internal model and interior molded tablet；The fluted flaring for placing magnetic drive pump isolation cover on described annular flaring tabletting；Described
Annular flaring tabletting outward flange has screw, and described annular flaring tabletting is bolted with interior molded tablet, described magnetic force
The flaring edge of pump isolation cover is clipped between annular flaring tabletting and interior molded tablet；Described cover cylinder internal model outline is cylinder
Shape, cover cylinder internal model is arranged in the cover cylinder of magnetic drive pump isolation cover, and is fully contacted with the cover cylinder inwall of magnetic drive pump isolation cover；Described
The inward flange of annular flaring tabletting be fixedly connected with cover cylinder internal model.
Described cover cylinder inner mold center has fixed via.
Also include excircle orientation mould, described excircle orientation mould includes outer annular flaring tabletting, cover cylinder external mold and outer molding
Piece；The fluted flaring for placing magnetic drive pump isolation cover on described outer annular flaring tabletting；Outside described outer molded tablet
Edge has a screw, and described outer annular flaring tabletting is bolted with outer molded tablet, the flaring of described magnetic drive pump isolation cover
Edge is clipped between outer annular flaring tabletting and outer molded tablet；Outer annular flaring tabletting and annular flaring tabletting are located at magnetic force respectively
The both sides of the flaring of pump isolation cover；The outer mold cavity profile of described cover cylinder is cylinder, and cover cylinder external mold is arranged on magnetic drive pump isolation
The cover drum outer wall of cover, and be fully contacted with the cover drum outer wall of magnetic drive pump isolation cover；The inward flange of described outer annular flaring tabletting
It is fixedly connected with cover cylinder external mold.
There is hole at described cover cylinder external mold center, for accommodating the raised axle sleeve of magnetic drive pump isolation cover.
First on lathe, clamping Internal hole positioning mould, adjusts concentricity, puts magnetic drive pump isolation cover, with pressing plate push down every
From cover, it is fixed on the excircle part processing that isolation cover is carried out on Internal hole positioning mould, after being completely processed, unloads Internal hole positioning mould
Frock, excircle orientation mould on clamping, adjust concentricity, put isolation cover into, after fixing again, carry out the interior hole portion of isolation cover
Divide processing.
In the past with after mould injection-compression molding because isolation cover does not have enough hardness cannot process, so having used another kind instead
The Shooting Technique that disposal molding is not processed, but Shooting Technique is limited it is impossible to be molded perfluoroethylene-propylene by material
（F46）, thus having had influence on magnetic drive pump range in industry；Design this frock it is simply that in order to solve mould injection-compression molding
Afterwards, isolation cover can be processed using frock, not limited by material, expand the range of this pump.
The processing tool of the magnetic drive pump isolation cover that the present invention provides, magnetic drive pump isolation cover adopts pressure injection technological forming, permissible
Clamping on lathe, may be machined, and workpiece can carry out turning under high-speed rotation, meets drawing requirement.
Brief description
Fig. 1 is the structural representation of magnetic drive pump isolation cover；
Fig. 2 is the structural representation of the Internal hole positioning mould of the present invention；
Fig. 3 is the structural representation of the excircle orientation mould of the present invention.
It is embodied as
The specific embodiment of the present invention is described with reference to the drawings.
The processing tool of magnetic drive pump isolation cover as shown in Figure 2, including Internal hole positioning mould；Described Internal hole positioning mould includes ring
Shape flaring tabletting 1, cover cylinder internal model 3 and interior molded tablet 2；On described annular flaring tabletting 1 fluted for place magnetic drive pump every
