Description

Coaxial convergent tube coupling forging die
Technical field
The utility model relates to a kind of forging die, and specifically, the utility model relates to a kind of tube coupling forging die, particularly a kind of for coaxial convergent tube coupling forging die.
Background technology
Crisscross industrial pipe network is mainly according to technological process and in conjunction with the installation site ordered arrangement of corollary equipment, and how many pipe diameters used is then determined by design rate-of flow.In industry pipe network, the pipeline of different bore connects usual by convergent tube coupling transition connection, and this kind of structure realizes the connection of different caliber pipe on the one hand, weakens position pipeline on the other hand and brings side effect, to improve medium fluidised form because caliber suddenlys change.Convergent tube coupling is the tube coupling that a kind of two ends caliber size does not wait, steel convergent tube coupling commercially available now, main adopt casting to add to be lathed shape mode realize batch micro operations.Along with the development of industrial technology, the industrial pipe network carrying high pressure of some special industries, the convergent tube coupling that prior art manufactures is because of tissue looseness, and insufficient strength, can not meet the supporting requirement of industrial pipe network of carrying high pressure.
Utility model content
The utility model, mainly for the deficiencies in the prior art, proposes the coaxial convergent tube coupling forging die that a kind of structure is simple, forming accuracy is high, production efficiency is high.The coaxial convergent tube coupling metallographic structure of excellent suitability for press forming is fine and close, and metallic fiber remains intact, and intensity is high, and voltage endurance capability is strong.
The utility model is achieved through the following technical solutions technical goal.
Coaxial convergent tube coupling forging die, it comprises core rod, patrix, die body and bed die.Described bed die is flat on press bench, is provided with shrinkage pool placed in the middle, is provided with axially extending bore in the middle part of shrinkage pool towards upper surface.Described die body upper and lower end face is respectively equipped with coaxial evagination shoulder, evagination shoulder down coordinates with the shrinkage pool of bed die upper surface locates, evagination shoulder is upward used for location and installation patrix, die body between two parties built-in by workpiece outer wall shape and size fixed gradually-reducing shape inner chamber.Its improvements are: described core rod is Multi-section shaft structure, the perpendicular core rod put with reduced diameter section down, axially extending bore along patrix inserts and runs through die body and bed die successively, reduced diameter section coordinates with the axially extending bore of bed die and guides core rod descending, until core rod top enlarged diameter section stop bit is in die body upper surface, form the closed forging die structure that core rod stage casing coordinates with die body inner chamber.
In said structure, described core rod is the coaxial major axis of three joints, and the shaft part being positioned at two ends is the cylinder axis that diameter does not wait, and stage casing is fixed gradually-reducing shape shaft part by inner hole of workpiece wall shape and size.
In said structure, the described core rod at least large 10mm of minor diameter Length Ratio die body one-tenth-value thickness 1/10 down, upper end major diameter Length Ratio patrix shrinkage pool end face is at least large 20mm of one-tenth-value thickness 1/10 of upper surface.
The utility model compared with prior art, has following good effect:
1, closed forging die structure is simple, making is easy;
2, core rod accurate positioning, excellent suitability for press forming steady quality;
3, the eccentric convergent tube coupling metallographic structure of excellent suitability for press forming is finer and close, and metallic fiber keeps complete, and intensity is high, and voltage endurance capability is strong.
Accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Coaxial convergent tube coupling forging die shown in Fig. 1, it comprises core rod 1 placed in the middle, and supporting patrix 2, die body 3 and bed die 4.Described bed die 4 is pedestals of a whole set of mould, and its horizontal is on supporting press bench, and its center is coaxial with principal axis of pressing machine.Bed die 4 is provided with shrinkage pool placed in the middle towards upper surface, is provided with axially extending bore in the middle part of shrinkage pool.Described die body 3 upper and lower end face is respectively equipped with coaxial evagination shoulder, evagination shoulder down coordinates with the shrinkage pool of bed die 4 upper surface locates, evagination shoulder is upward used for location and installation patrix 2, and die body 3 is built-in workpiece 5 outer wall shape and size and the fixed gradually-reducing shape inner chamber pressed between two parties.Described core rod 1 is Multi-section shaft structure, and the present embodiment core rod used 1 is the homoaxial major axis of three joints, and the shaft part being wherein positioned at two ends is the cylinder axis that diameter does not wait, and stage casing is fixed gradually-reducing shape shaft part by workpiece 5 inner hole wall shape and size.During actual forging and stamping, with reduced diameter section down, the axially extending bore along patrix 2 inserts and runs through die body 3 and bed die 4 successively the perpendicular core rod 1 put.In order to ensure core rod 1 in forging and stamping process all the time with die body 3 coaxial, the utility model is by core rod 1 reduced diameter section extended length down, this length is at least greater than die body 3 one-tenth-value thickness 1/10 10mm, the present embodiment is for forging and pressing the convergent tube coupling of bore 50 ~ 25, the thick 70mm of die body 3, core rod 1 reduced diameter section length used is decided to be 80mm.When core rod 1 is descending, first coordinated by the axially extending bore of reduced diameter section with bed die 4, this axially extending bore guides core rod 1 directed descending.The tubular blank that descending core rod 1 is opposite in die body 3 inner chamber is exerted pressure, and exerts pressure to terminate in core rod 1 top enlarged diameter section and encounter die body 3 upper surface.In addition, core rod 1 upper end major diameter Length Ratio patrix 2 shrinkage pool end face is long to the one-tenth-value thickness 1/10 of upper surface, the long 20mm of the present embodiment.Use the coaxial convergent tube coupling forging die formed by above-mentioned each, the convergent tube coupling metallographic structure of excellent suitability for press forming is finer and close, and metallic fiber keeps complete, guarantees that the tube coupling intensity of excellent suitability for press forming is high, and voltage endurance capability is strong, can meet the supporting requirement of high pressure pipe network.
