Abstract
The utility model relates to a kind of double screw pump body high pressure chest stamping tooling, be characterised in that: comprise with the cylinder axle of pump housing endoporus clearance fit, to be fixed on an axle outer wall by securing member and to prevent a gland of axle axial float and O type circle, described cylinder axle is welded by the cylindrical shell of metal material, outer support circle and inner support to form, described outer support snare is contained in the outside two ends place of cylindrical shell, and described inner support and cylindrical shell two ends internal orifice weld admittedly.Advantage is: this stamping tooling, owing to adopting cylinder axle construction, not only can enhance the compressive strength of stamping tooling, and structure is simple, accurately swift to operate, can be met two-screw pump double-layer pump body high pressure chest and suppress requirement.
Description
Technical field
The utility model belongs to screw pump manufacturing technology field, particularly a kind of double screw pump body high pressure chest stamping tooling.
Background technology
At present, the range of application of two-screw pump is more and more extensive, under being usually required to be applied in the working environment of high pressure, therefore has certain requirement to the bearing capacity of the high pressure chest of two-screw pump double-layer pump body.Traditional pump housing high pressure chest is suppressed and is usually adopted two pieces of metal closure plates to be fastened on the both ends of pump housing high pressure chest respectively by screw shutoff, and is sealed by O-ring seal.When squeezing into high pressure to pump housing high pressure chest, because the intensity of metal closure plate limits, making it deform, and departing from the pump housing, and then cause bulge test failure.
Summary of the invention
The utility model for solve in known technology the technical matters that exists and provide that a kind of structure is simple, convenient operation and the double screw pump body high pressure chest stamping tooling that pump housing high pressure chest bearing capacity requires can be met.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
Double screw pump body high pressure chest stamping tooling, it is characterized in that: comprise with the cylinder axle of pump housing endoporus clearance fit, to be fixed on an axle outer wall by securing member and to prevent a gland of axle axial float and O type circle, described cylinder axle is welded by the cylindrical shell of metal material, outer support circle and inner support to form, described outer support snare is contained in the outside two ends place of cylindrical shell, and described inner support and cylindrical shell two ends internal orifice weld admittedly.
The utility model can also adopt following technical scheme:
Described outer support circle is shaped with the male half coupling for mounting O-shaped rings.
The inner stopper described gland being shaped with through hole and coordinating with cylinder axle, and fastening by the outer support circle of bolt and cylinder axle.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, namely pump housing high pressure chest is carried out when suppressing, this stamping tooling is put into the pump housing 6 by overhead traveling crane by operating personnel, this stamping tooling and pump housing inner hole are installed, then can carry out the bulge test of high pressure chest.This stamping tooling, owing to adopting cylinder axle construction, not only can enhance the compressive strength of stamping tooling, and structure is simple, accurately swift to operate, can be met two-screw pump double-layer pump body high pressure chest and suppress requirement.

In figure: 1, cylinder axle; 1-1, cylindrical shell; 1-2, outer support circle; 1-3, inner support; 2, O type circle; 3, gland; 4, packing ring; 5, securing member; 6, the pump housing.
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 3, double screw pump body high pressure chest stamping tooling, comprising with the cylinder axle 1 of pump housing endoporus clearance fit, being fixed on an axle outer wall for preventing a gland of axle axial float 3 and O type circle 2 by securing member 5.Described cylinder axle is welded by the cylindrical shell 1-1 of metal material, outer support circle 1-2 and inner support 1-3 to form, and described outer support snare is contained in the outside two ends place of cylindrical shell, and described inner support and cylindrical shell two ends internal orifice weld admittedly.Described O type circle adopts standard component, can meet the seal request of stamping tooling, and interchangeability is strong.
In the present embodiment, described cylindrical shell 1-1, outer support circle 1-2 and inner support 1-3 all adopt steel matter to make, and the rigidity that so not only can meet an axle requires but also can alleviate the weight of stamping tooling.Cylinder axle requires to carry out finishing according to the allowance of pump housing endoporus, and described cylinder axle cylindrical tolerance is f7, with pump housing endoporus clearance fit, therefore can be easy to put it into pump housing endoporus.
In the present embodiment, described outer support circle is shaped with the male half coupling for mounting O-shaped rings, and described cylinder axle male half coupling requirement on machining accuracy is f7, and its size designs according to the size of O type circle, and O type circle can be pressed into and be not easy to come off by requirement completely.
In the present embodiment, the inner stopper described gland being shaped with through hole and coordinating with cylinder axle, and fastening with the outer support circle of cylinder axle by securing member 5, the size of described securing member according to Strength co-mputation, need should be able to meet the high pressure requirement suppressed.
In the present embodiment, described cylinder axle is also shaped with and facilitates overhead traveling crane lifting screw.
Principle of work of the present utility model is:
Refer to Fig. 4, first cylindrical shell 1-1, outer support circle 1-2 and inner support 1-3 are processed respectively by drawing, secondly this three part is welded into an axle 1.According to the excircle dimension of the roughing dimensioned cylinder axle of pump housing endoporus, all the other sizes of cylinder axle machine according to drawing.Gland survives according to drawing dimensioned.At cylinder axle stop portion press-in O type circle 2, and by securing member 5, gland is connected with cylinder axle.Then by overhead traveling crane, this stamping tooling is put into the pump housing 6, carry out the bulge test of high pressure chest.
The embodiment described in the utility model accompanying drawing is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
