Abstract
The utility model discloses a high temperature hot-shape-righting circulating water cooling solid self-lubricating cone. The high temperature hot-shape-righting circulating water cooling solid self-lubricating cone is characterized by comprising a pyramid-shaped cone body and a connecting pull rod; the tail end of the pyramid-shaped cone body is connected with the front end of the connecting pull rod through threads and a sealing ring; cylindrical solid lubricating materials are inlaid on the outer surface of the pyramid-shaped cone body; circulating water cooling chambers are formed in the pyramid-shaped cone body and the connecting pull rod. By means of the high temperature hot-shape-righting circulating water cooling solid self-lubricating cone, an oil supply device is not needed, design, the structure and the like are substantially simplified through the oilless performance, cost is reduced, and the design time is saved. The circulating water cooling chamber is formed in the pyramid-shaped cone body; when working, the cone is cooled through circulating water, so that the excessive-high temperature is avoided, and straining or locking caused when the cone and a die relatively slide and a guide key and the cone relatively slide are avoided.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of recirculated water cooling self-lubricating solid cone that applies to high warm school shape.
Background technology
Machinery expanding is during welded tube is produced, to guarantee that one important procedure of tube quality, machinery expanding are a kind of materials processing technologies that adopts skewback reaming principle, makes pipe generation plastic deformation by distinguish punch.Machinery expanding belongs to the rigid die Bulging Technology in tubing secondary operations field, machinery expanding can be eliminated the part residual stress causing when being shaped and welding, improve steel pipe internal stress distribution, the circularity and the linearity that make steel pipe reach to stipulate in standard reduce difficulty of construction simultaneously.Hole enlargement has become one important procedure guaranteeing into pipe quality in welded tube production.
Steel tube expansion is one of key equipment of Longitudinal SAW Pipe production line.Expanding machine, as a kind of very crucial technical equipment that improves tube quality, is used more and more in tubulation is produced.Yet along with steel tubing quality and grade, other improves, increase, particularly thermal power plant, nuclear power station, Aero-Space and the military field of steel pipe thickness be to σ under room temperature condition
b>=1700 MPa, σ
0.2the hole enlargement of the ultra high strength alloy steel steel pipe of>=1400 MPa, normal temperature expanding technology can not meet instructions for use.And Aero-Space and military field are also very strict to the required precision of steel pipe, normal temperature expanding technology more can not meet the demands.For this type of high strength, high precision steel tube, be mainly that employing jack is manually repeatedly repeatedly proofreaied and correct full circle or adopted lathe to carry out turning processing at present, reach needed circularity.
Easily there is the unlubricated and locking phenomenon of cone in the cone under normal temperature operating mode, cause normal temperature expanding technology can not meet the high accuracy hole enlargement requirement of high strength high precision steel tube under 650 ℃～850 ℃ conditions of school shape workpiece temperature.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defect existing in prior art, and a kind of hot school shape recirculated water cooling self-lubricating solid cone being adapted under the shape operating mode of high temperature school is provided.
The purpose of this utility model realizes by the following technical solutions: the warm school of this height shape recirculated water cooling self-lubricating solid cone, and it comprises water chestnut conical taper main body and cylinder lever connecting rod; The tail end of described water chestnut conical taper main body adds sealing ring with the front end of cylinder lever connecting rod employing screw thread and is connected; The outer surface of described water chestnut conical taper main body is inlaid with cylindrical solid lubricant; In described water chestnut conical taper main body and cylinder lever connecting rod, be provided with recirculated water cold house.
Specifically, described recirculated water cold house comprises that runs through the cold water pipe being installed in water chestnut conical taper main body and cylinder lever connecting rod axis place installing hole, in the tail end of the tail end of cold water pipe in cylinder lever connecting rod, and seal UNICOM with the inlet opening in cylinder lever connecting rod tail end, the water inlet UNICOM on inlet opening and cylinder lever connecting rod surface, the front end of cold water pipe is positioned at water chestnut conical taper body front end hole; The described diameter that is greater than cold water pipe for the installing hole diameter at axis place in the water chestnut conical taper main body of cold water pipe and cylinder lever connecting rod is installed, makes the space between the outer and installing hole of cold water pipe form cold water circulation canal; The surface that is positioned at the cylinder lever connecting rod of inlet opening front end at cold water pipe tail end is provided with delivery port, delivery port Yu Gai space UNICOM.
Specifically, described cylindrical solid lubricant is graphite or molybdenum bisuphide.
Operating temperature of the present utility model is between 200 ℃ to 450 ℃, and the burning-point (or flash-point) of general lubricant grease is generally 200 ℃ of left and right.The material of water chestnut conical taper main body of the present utility model is alloy nodular cast iron, because the technique that the employings such as solid lubricant graphite (blacklead) or molybdenum bisuphide are inlayed is imbedded cone surface, there is high-low temperature resistant serviceability, Applicable temperature is at-200 ℃ to 600 ℃, it has guaranteed lubricating between worst hot case bed die and centrum, has broken through the limitation that cone cannot be lubricated under worst hot case.In water chestnut conical taper main body, have cooling chamber, make by recirculated water that its cone is cooling to be unlikely to pull when excess Temperature causes cone and mould, feather key and cone relative sliding or the phenomenon of locking occurs in cone when work.
The utility model is applicable to the place that high warm school shape cannot be refueled or be difficult to refuel, and oil-free lubrication or few oil lubrication can not maintained in use or few maintenance, and exempted due to the risk causing for shortage of oil.The utility model, without fueller, can refuel in the course of work, therefore can save a large amount of installation and operation costs.Without oiling, design, structure etc. are significantly simplified, reduced cost, saved design time.The utility model is applicable to the hole enlargement of the various high strength high precision steel tubes that chemical composition is different, and the high strength high precision steel tube that uses the utility model school shape to produce will be used widely in oil, natural gas transport, thermal power plant, nuclear power station, Aero-Space and military field.
The utility model successfully applies to expanding technology the shape field, hot school of high strength high accuracy cylindrical work pieces, effectively solved the school shape of high strength high precision steel tube under worst hot case, shorten process time, improved machining accuracy and production efficiency, reduced labor strength.
