Abstract

The invention relates to an even wall thick hollow screw pump rotor molding machine which is characterized in that the molding machine consists of a framework, an internal model and an external model. The internal model is conical shape. An axial via hole is arranged on the internal model. The inner wall of the via hole is spiral on the external of a screw rod. A mold cavity for processing the screw pump rotor is formed. Two ends of the internal model are fixed on the framework by screws. The external model is conical annular shape and is arranged on the outside of the internal model. The inner wall of the external model is closely combined with the outside of the internal model. Two ends of the external model are also fixed on the framework by screws. Steel pipes can be used for processing the screw pump rotor. Large amount of steel can be saved the production cost can be lowered greatly. And the even wall thick hollow screw pump rotor molding machine has the advantages of high production precision, high production efficiency, low manufacturing cost and wide application. The processing size is not confined.

Description

Even wall thick hollow screw pump rotor molding machine
Technical field
The present invention relates to a kind of screw pump rotor make-up machine, specifically relate to a kind of even wall thick hollow screw make-up machine (comprising single head, double end, three, four-head, five, six first-class screw pump rotors).
Background technology
The processing of screw pump rotor is normally milled and is processed by extension pitch, whirlwind by machine tool C6136, C6280.Present ubiquitous problem is: the first, the ratio of precision of this machine tooling is lower, and roughness ratio is relatively poor; The second, Jia Gong efficient is low, the processing of incompatible extensive screw pump rotor; Three, cost of processing is than higher, and at first it is with solid steel unit processing, moreover needs brazed shank tool in the middle of the process of processing, has increased manufacturing cost! If on Digit Control Machine Tool, process, then need on four screw rod dedicated numerical control machining center, process, four lathes will be got well millions of units, processing charges costliness! Require also than higher for the operator; Four, the length of screw rod is subjected to the restriction of the length of lathe, generally all is below six meters.Five, the solid screw quality is big, and centrifugal force is big, the stator rapid wear.In addition, manufacture process speed is also slow, and consumed energy is bigger.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide that a kind of process velocity is fast, low cost of manufacture, and can reduce raw material, the even wall thick hollow screw pump rotor molding machine of increasing work efficiency.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of even wall thick hollow screw pump rotor molding machine, it is characterized in that comprising framework 4, internal mold 2 and external mold 3, described internal mold 2 profiles are taper, be processed with an axial through hole at internal mold 2 centers, the spirality that is shaped as the screw rod outside of the inwall of through hole, form the die cavity of processing screw pump rotor, internal mold 2 two ends are fixed on the framework 4 by screw; Described external mold 3 is unitary tapered ring-type, be enclosed within the outside of internal mold 2, combine closely in the outside of the inwall of external mold 3 and internal mold 2, the two ends of external mold 3 also are fixed on the framework 4 by screw, the external mold hold down gag is installed on described framework, and the external mold hold down gag is installed in frame upper side versatilely, can be fixed on the framework by screw, the downside of external mold hold down gag is the inclined plane, is close on the outer wall of external mold.
Aforesaid even wall thick hollow screw pump rotor molding machine is characterized in that described internal mold 2 for along the circumferential direction being divided into three, is fixed on the framework by screw respectively, supports with spring between three internal molds, is subjected to external mold 3 constraints.
The invention has the beneficial effects as follows: the present invention can process screw pump rotor with steel pipe, can save a large amount of steel, greatly reduce production costs, and production precision height, working (machining) efficiency height, low cost of manufacture, processing length is unrestricted, and is widely applicable.
Description of drawings
Fig. 1 be even wall thick hollow screw pump rotor molding machine of the present invention structural representation.
The specific embodiment
Below in conjunction with accompanying drawing even wall thick hollow screw pump rotor molding machine of the present invention is carried out specific description.
Fig. 1 be even wall thick hollow screw pump rotor molding machine of the present invention structural representation.As shown in the figure, even wall thick hollow screw pump rotor molding machine of the present invention comprises framework 4, internal mold 2 and external mold 3, internal mold 2 profiles are taper, on internal mold 2, be processed with an axial through hole, the spirality that is shaped as the screw rod outside of the inwall of through hole, form the die cavity of processing screw pump rotor, internal mold 2 two ends are fixed on the framework 4 by screw.External mold 3 is unitary tapered ring-type, is enclosed within the outside of internal mold 2, and external mold 3 is fixed on the base.
Internal mold 2 is swaging dies of screw pump rotor, and external mold 3 is fixed dies, and with steel pipe extrusion modling in internal mold 2, steel pipe has just formed screw pump rotor.Check the requirement that whether screw pump rotor reaches needs! If satisfy just passable! The stroke of internal mold 2 can be adjusted, and needs only to change internal mold 2 when other description of needs.
Simultaneously, for the screw pump rotor of more convenient processing all size, internal mold 2 is fixed on the framework by screw respectively for along the circumferential direction being divided into three, supports with spring between three internal molds, is subjected to external mold 3 constraints, can regulate the distance between three.
In addition, move, the external mold hold down gag is installed on framework 4 for preventing internal mold 2 and external mold 3, the external mold hold down gag is installed in the upside of framework 4 versatilely, can be fixed on the framework by screw, the downside of external mold hold down gag is the inclined plane, is close on the outer wall of external mold 3.Play effect fixing and that compress.
Even wall thick hollow screw pump rotor molding machine of the present invention is not subjected to any restriction for the length of screw rod, can process the screw pump rotor more than six meters, has improved operating efficiency greatly.Simultaneously, the screw pump rotor precision height that extruding is come out, process velocity is fast, really realizes efficient, energy-conservation!
The speed of the present invention's processing is fast, is 30 times of common process method efficient; Cost of processing is lower, is fit to large-scale production, can replace original steel unit with steel pipe, and its cost is about 20% of a former cost, can save lot of materials.Technological precedence, market prospects are extensive.
Above-mentioned enforcement does not limit the present invention in any form, and all technical schemes that mode obtained of taking to be equal to replacement or equivalent transformation all drop in protection scope of the present invention.
