Description
Technical field
The utility model relates to pipeline fields, and in particular to stainless steel tube flaring tooling.
Background technique
Currently, steel pipe can undergo bend pipe after making when workshop is using thin-wall stainless steel production cooling water pipe,
Rotary-cut (cutting away pipe end excessive portion) process, after the process stainless steel tube port can it is deflated because of various situations or
Necking, this has seriously affected the assembly and welding of subsequent elbow, because elbow is by manually injecting nozzle, if stainless
The port circularity of steel pipe is poor, and the reserved socket of elbow is difficult to inject stainless steel tube, this will seriously affect the welding sequence
Productive temp, while also increasing the labor intensity of worker, therefore existing be badly in need of wanting a kind of device to solve existing issue.
Summary of the invention
In order to solve the above technical problems, reaching will not the purpose of this utility model is to provide stainless steel tube flaring tooling
The round swollen circle in stainless steel tube port simultaneously controls the size after swollen mouth, and then improves the purpose of production efficiency.
In order to achieve the above purposes, the technical solution adopted by the utility model is:
A kind of stainless steel tube flaring tooling, including expansion set ontology, mandril and Power Component, the mandril pass through Power Component
Distending shrinks expansion set ontology；
The expansion set ontology is multi-diameter shaft, is provided through the conical through-hole being coaxially arranged, institute in the multi-diameter shaft
It states and is provided with annular groove on multi-diameter shaft outer surface, ring spring is provided on the annular groove, the expansion set ontology includes six
Expansion block, the expansion block are arranged with the axisymmetrical of conical through-hole.
Further, the Power Component is the hydraulic cylinder with piston rod.
Further, the mandril includes cylindrical bar and cone, and one end of the cylindrical bar connects on the piston rod, and it is another
One end is connected in cone, and the top of the cone is located in conical through-hole.
Further, the taper of the cone and conical through-hole is 16 °.
Further, the top of the cone is designed using rounded corner.
The utility model compared with prior art, the beneficial effect is that: hydraulic cylinder, which plays, provides power for the movement of mandril,
Can mandril smoothly be moved simultaneously, expansion set ontology is played with the conical through-hole that taper is 16 ° is arranged inside when top
When bar is pushed into conical through-hole, the size of adjustable expansion set ontology, and then stainless steel tube of the adjusting set on expansion set ontology
Caliber, may finally guarantee the circularity of stainless steel tube port and the diameter of control port, the end of mandril uses rounding
Angle can be designed so that stainless steel tube can smoothly into or exit conical through-hole.

In figure: 1 expansion set ontology；2 expansion blocks；3 annular grooves；4 multi-diameter shafts；5 conical through-holes；6 mandrils；7 cylindrical bars；8 cones.
Specific embodiment
By the technology contents of the utility model are described in detail, construction feature, are reached purpose and efficacy, reality is hereby enumerated below
It applies example and attached drawing is cooperated to be explained in detail.
In the description of the present invention, it should be understood that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion is signified
Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this is practical
The limitation of novel protected range.
Refering to Figure 1, and combine Fig. 2 and Fig. 3 shown in, the utility model provides a kind of embodiment:
A kind of stainless steel tube flaring tooling, including expansion set ontology 1, mandril 6 and Power Component, the mandril 6 pass through power
Component distending shrinks expansion set ontology 1；
The expansion set ontology 1 is multi-diameter shaft 4, and the design of multi-diameter shaft 4 is used to play to cover the stainless steel tube on multi-diameter shaft 4
One support platform is provided, the conical through-hole 5 being coaxially arranged, 4 appearance of multi-diameter shaft are provided through in the multi-diameter shaft 4
It is provided with annular groove 3 on face, ring spring is provided on the annular groove 3, the expansion set ontology 1 includes six expansion blocks 2, described
Expansion block 2 is arranged with the axisymmetrical of conical through-hole 5, and ring spring, which not only acts as binding expansion block 2, becomes unified whole, also acts as and works as
When mandril 6 exits expansion set ontology 1, the effect of expansion set ontology 1 is shunk.
Further, the Power Component is the hydraulic cylinder with piston rod.
Further, the mandril 6 includes cylindrical bar 7 and cone 8, and one end of the cylindrical bar 7 connects on the piston rod, and
Its other end is connected in cone 8, and the top of the cone 8 is located in conical through-hole 5.
The movement of mandril 6 can be made more steady using Driven by Hydraulic Cylinder.
Further, the cone 8 and the taper of conical through-hole 5 are 16 °.
Conical through-hole 5, which is 16 °, can make mandril 6 when being inserted into conical through-hole 5, can constantly adjust multi-diameter shaft 4
Small axis diameter, until reach preset diameters, the caliber that can meet stainless steel tube at this time is certain value, while making its pipe
Mouth is round and smooth.
Further, the top of the cone 8 is designed using rounded corner.
Facilitate mandril 6 deeply or exits in conical through-hole 5.
Working principle: Driven by Hydraulic Cylinder mandril 6 moves upwards, mandril 6 is deep into conical through-hole 5, at this time multi-diameter shaft 4
Diameter on upper axis is increasing, when the diameter of upper axis reaches the diameter of preset stainless steel tube, hydraulic cylinder stop motion, into
And the caliber for the stainless steel tube being sleeved on the upper axis of multi-diameter shaft 4 is made to reach default caliber, Driven by Hydraulic Cylinder mandril 6 is transported downwards
Dynamic, mandril 6 exits conical through-hole 5, and multi-diameter shaft 4 is shunk under the action of ring spring, removes stainless steel tube, completes primary add
Work constantly repeats the above process and realizes batch machining production.
In conclusion the preferred embodiment of only the utility model, does not limit the protection scope of the utility model with this, it is all
Equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual are all what the utility model patent covered
