Abstract
The utility model relates to a spiral warp oval section heat exchange tube parallel-axis rolling mill machine and tool, which is composed of a plurality of pairs of parallel-axis rolling pairs 1, the center distances of which can be adjusted, a synchronization mechanism 2, a motive power source 3, etc. The utility model is characterized in that the rolling pairs are provided with parallel axial lines and can be contrarotated synchronously by the driving of the motive power source and the synchronization mechanism, a rolling groove of the roll is in the shape of the oval section of the spiral warp, and the curved surface of the partial rolling groove is amended. The utility model has the advantages of better stability, high rate of rolled and finished products, high productive efficiency and easy regulation and operation.
Description
The utility model relates to a kind of manufacturing facility of augmentation of heat transfer heat exchanger tube, particularly makes common heat exchanger tube be shaped to the rolling facility of helically twisted elliptic-section heat exchange pipe in an operation of rolling by the parallel axes rolling.
Utility model patent ZL97221659.6 " helically twisted elliptic-section heat exchange pipe " makes it have comprehensive good enhanced heat exchange performance because it forces effects such as eddy flow disturbance.Intersecting axle rolling embodiment described in this utility model patent, have real preferably answering property for rolling different helically twisted pitch and elliptic-section size, but exist the difference of heat exchanger tube surface condition (as greasy dirt) and mechanical performance to cause the unstability or the difference of helically twisted pitch.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of helically twisted elliptic-section heat exchange pipe parallel axes rolling facility are provided, and makes the rolling quality of heat exchanger tube have stability preferably, improves rolling yield rate.
The purpose of this utility model is achieved in that
(1) the groove processing and manufacturing with roll becomes helically twisted part elliptic-section shape.Do not interfere in order to make in the operation of rolling, part groove curved surface need be revised (the part curved surface that correction causes interference).
(2) use is a pair of or several right to parallel axes roll synchronous rotation and that have this special groove, and common heat exchanger tube is shut out helically twisted elliptic-section shape at an operation of rolling central roll.
(3) because the pipe two ends still keep its circular cross-section, the right centre-to-centre spacing of roll should be adjustable within the specific limits.
The utility model compared with prior art has the following advantages.
Rolling helically twisted pitch and elliptic-section size depend primarily on the size of roll, and rolling have preferably stability, a high and production efficiency height of rolling yield rate; The parallel axes milling train is easy to adjust and operation than the intersecting axle milling train simultaneously.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of helically twisted elliptic-section heat exchange pipe parallel axes rolling facility.Among the figure, 1 is that the parallel axes roll of tunable center distance is right, and 2 is lazy-tongs, and 3 is power source.Have only the parallel axes roll of a pair of tunable center distance right among Fig. 1, its lazy-tongs are synchromesh gear mechanism.When roll rotates synchronous backward under the driving of power source and lazy-tongs, treat that tube rolling is helically twisted elliptic-section heat exchange pipe at the extrusion rolling effect compacted under of roll groove face.
Fig. 2 and Fig. 3 are the roll exemplary plot.Among Fig. 2, the groove of roll has the helically twisted part elliptic-section shape of a pitch, and the part flute profile is through revising.Among Fig. 3, the groove of roll has the helically twisted part elliptic-section shape of two pitches, and the part flute profile is through revising, and bottom land opens circumferential groove, to reduce the relative slippage of roll and rolled pipe.
See Fig. 1, Fig. 2, concrete structure of the present utility model is as follows:
Helically twisted elliptic-section heat exchange pipe parallel axes rolling facility by some parallel axes rolls to the tunable center distance to 1, lazy-tongs 2 and power source 3 etc. form.The right axis of roll is parallel to each other, and roll synchronous backward under the driving of power source and lazy-tongs rotates.The right quantity of parallel axes roll recommends to select for use a pair of or two pairs.
The groove of roll is helically twisted part elliptic-section shape.Do not interfere in order to make in the operation of rolling, part groove curved surface need be revised.In order to reduce the relative slippage of roll and rolled pipe, bottom land can be opened circumferential groove.In order to form various concavo-convex walls to strengthen the disturbance of convection cell, can open different translots and skewed slot at the groove curved surface on rolling helically twisted elliptic-section heat exchange pipe surface.The groove curved surface of opening translot and skewed slot also can increase the friction in the operation of rolling, reduces roll and the relative slippage of rolled pipe or the possibility of skidding.
Lazy-tongs are in order to make the parallel axes roll to synchronous backward in operation of rolling rotation, thereby guarantee rolling helically twisted elliptic-section heat exchange pipe cross sectional shape and size stability.Lazy-tongs can also can be synchronization link mechanism for synchromesh gear mechanism.Lazy-tongs are according to the right difference of roll and respective change.
Pitches such as the pitch of the helically twisted part elliptic-section shape of roll groove can be the constant pitch distance, also can be irregular pitch, and is preferred.The helically twisted of roll groove can be continuous distortion, also can be discontinuous distortion.The cross sectional shape of the helically twisted elliptic-section heat exchange pipe that it rolls out can have the non-round symmetry and the near symmetrical cross section of major and minor axis for ellipse, approximate ellipsoidal and oval row etc., and part can also be circular cross-section and/or fillet surface.When roll groove was the part elliptic-section shape of continuous helical distortion, its heat exchanger tube that rolls out was continuous helically twisted elliptic-section heat exchange pipe; When roll groove was discontinuous helically twisted part elliptic-section shape, its heat exchanger tube that rolls out was discontinuous or is interrupted the helically twisted elliptic-section heat exchange pipe that changes direction.The helically twisted quantity of groove curved surface can be unrestricted.
Claims (3)
1, helically twisted elliptic-section heat exchange pipe parallel axes rolling facility, by some parallel axes rolls to the tunable center distance to 1, lazy-tongs 2 and power source 3 etc. form, it is characterized in that roll parallels to the axis to having, and synchronous backward rotates under the driving of power source and lazy-tongs; The groove of roll is helically twisted part elliptic-section shape, and its part groove curved surface is through revising.
2, according to the described helically twisted elliptic-section heat exchange pipe parallel axes rolling facility of claim 1, it is characterized in that the helically twisted of roll groove can also can also can change the distortion of direction for continuous distortion for discontinuous or interruption for irregular pitch twists apart from distortion for constant pitch.
3, according to the described helically twisted elliptic-section heat exchange pipe parallel axes rolling facility of claim 1, it is characterized in that the helically twisted cross sectional shape of roll groove can have the non-round symmetry and the near symmetrical cross section of major and minor axis for ellipse, approximate ellipsoidal and oval row etc., part can also be circular cross-section and/or fillet surface.
