Abstract
The utility model discloses a novel device for producing spiral high-finned tubes, which comprises a winding drum, a pull rod and a support rod, and the pull rod and the support rod are connected with the winding drum. During winding, one end of a finned tube is inserted into the support rod, one end of the support rod is adjusted close to the position of the tangent point of the winding drum, the other end of the support rod is fixed along the direction of the extended line of the tangent, the other end of the finned tube is inserted into the pull rod, the pull rod drives the copper tube to wind when the winding drum rotates, and meanwhile, depending on the function of the support rod, the tube is spirally wound. The utility model is applicable to the winding of high-finned tube products with isomerized outer tube surfaces.
Description
Technical field
The utility model relates to a kind of new equipment of production screw type fins of high teeth pipe.
Background technology
The screw type heat exchange is with copper and copper alloy high finned tube coiled with heat exchange with copper and copper alloy high finned tube, fields such as the main application and the energy, chemical industry, machine-building, make the contact of the effectively big density of cold and hot matchmaker, prevent energy dissipation or loss, flame reaches effective coating under heating condition, reaches the ability of Fast Heating.In oil, hydrothermal exchange, under the conditions such as water, hydrothermal exchange, exchange capability of heat improves greatly, reaches fast effectively, and realize installation requirement easily under limited environment, promptly places at internal tank to reach the heat exchange purpose.This product also is used in the bearing shell of heavy mechanical equipment and needs temperature to control the heating and the cooling at higher position.This product has substituted common copper pipe with capacity of heat transmission efficiently, mended Mi copper pipe in traditional heat exchanger and heat that iron plate connection causes the easily leakage problem of back that rises, with the high finned tube coiled, do not produce and problems such as other material is connected, integral body is a copper high finned tube coiled, makes the Product Safety height, heat energy is all absorbed by copper pipe, product heat exchanger effectiveness height, compact shape, easy for installation.Because tube surfaces is a fin structure, fin is thin with copper and copper alloy high finned tube in the screw type heat exchange, and the bending of finned tube need be exerted pressure to tubing, easily produces crooked and lodging on the fin if pressure acts on.So it is crooked many with lodging that the major defect of traditional finned tube helical form process technology is a fin, it is bad to be shaped.
Summary of the invention
The purpose of this utility model is to process existing shortcoming at above-mentioned finned tube helical form, and a kind of reasonable in design is provided, and helical form is processed the screw type high finned tube production equipment that the back fin is not crooked and lodge.
In order to achieve the above object, the utility model mainly adopts following technology to realize.
Because tube surfaces is a fin structure, fin is thin with copper and copper alloy high finned tube in the screw type heat exchange, and the bending of finned tube need be exerted pressure to tubing, easily produces crooked and lodging on the fin if pressure acts on.For overcoming the lodging problem, finned tube bending process technology of the present invention is by reel and coupled draw bar and support bar is formed.
Reel adopts steel plate to be curled into, and playing curls supports and the effect of typing, is used to support internal diameter after curling during with copper and copper alloy high finned tube in the heat exchange of coiled coil type.
Drawing bar is the one section steel round bar that is fixed on the reel side, and diameter is slightly less than pipe internal diameter and the reel side fixes, and plays fixedly tubing and the effect of drawing tubing.
Support bar is that diameter is slightly less than pipe internal diameter along one section steel round bar of reel upper end tangential direction, locates to fix in reel upper end tangent extending line direction 8 meters (tubing initial lengths), plays the effect of supporting copper pipe and forming crooked pressure.
When curling, finned tube one end is inserted support bar, one end of support bar is adjusted near position, reel point of contact, the other end is fixed on the extended line direction of tangent line, bar is drawn in the insertion of the finned tube other end, and reel draws bar drive copper pipe and curls when rotating, rely on the effect of support bar simultaneously, it is crooked that tubing is produced, and forms spirality.
Its principle is to adopt support bar to insert tubing inside, applies active force by the intensity of support bar at the tubing endoporus, can not damage the outer fin of tubing.
The purpose of this utility model is the shortcoming that exists when curling at above-mentioned copper high finned tube to provide a kind of production production equipment, makes its fin when curling distortion not occur and lodges.
The utility model compared with prior art has following tangible advantage and innovation: it is indeformable that (1) present technique has the curling back of fin, non-lodging.(2) present technique can varying sized as requested specification.
The utility model is applicable to that pipe outer surface has curling of different in nature fins of high teeth pipe product.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is a process units schematic diagram of the present utility model.
The specific embodiment
As shown in the figure, the utility model is mainly by reel 3 and coupled draw bar 1 and support bar 5 is formed.Reel 3 adopts steel plates to be curled into, and playing curls supports and the effect of typing, is used to support internal diameter after curling during with copper and copper alloy high finned tube in the heat exchange of coiled coil type.Drawing bar 1 is the one section steel round bar that is fixed on the reel side, and diameter is slightly less than pipe internal diameter and the reel side fixes, and plays fixedly tubing and the effect of drawing tubing.Support bar 5 is that diameter is slightly less than pipe internal diameter along one section steel round bar of reel upper end tangential direction, and tangent extending line direction place is fixed in the reel upper end, plays the effect of supporting copper pipe and forming crooked pressure.
Embodiment
When curling, fins of high teeth pipe 4 one ends are inserted support bar 5, one end of support bar 5 is adjusted near position, reel 3 point of contact, the other end is fixed on the extended line direction of tangent line, bar 1 is drawn in the insertion of fins of high teeth pipe 4 other ends, and reel 3 draws bar 1 drive fins of high teeth pipe 4 and curls when rotating, rely on the effect of support bar 5 simultaneously, it is crooked that tubing is produced, and forming spirality has bending 2.
The utility model is applicable to that pipe outer surface has curling of different in nature fins of high teeth pipe product.
Claims (2)
1. a new equipment of producing screw type fins of high teeth pipe is made up of reel (3), it is characterized in that reel (3) respectively with draw bar (1) and be connected with support bar (5).
