Abstract
The invention discloses a device for producing a seamless copper pipe, belonging to the production device. The structure of the device comprises a spinning device, a pre-stretching outer mould, a pre-stretching swim core, a cylindrical core head and a sizing mould, wherein the pre-stretching outer mould, a spinning device and the sizing mould are sequentially arranged a copper pipe; the pre-stretching swim core and the cylindrical core head are arranged in the copper pipe respectively and connected through a connection rod; the pre-stretching swim core is matched with the pre-stretching outer mould at the outer side of the copper pipe; and the spinning device is arranged on the copper pipe at the outer side of the cylindrical core head. Compared with the prior art, the device for producing the seamless copper pipe disclosed by the invention has the characteristics that the pass elongation coefficient of reaches 1.6-2.0, the wall thickness of the copper pipe is stable, the pipe breakage caused by stretching is avoided and the like, and thus the device has good popularization and application values.
Description
Technical field
The present invention relates to a kind of process units, the device of the seamless copper pipe that especially a kind of production ultra-thin-wall air-conditioning and refrigeration plant are used.
Background technology
Along with air-conditioner develops to miniaturization, economization, high energy efficiency direction, air-conditioning condenser and evaporimeter progressively tend to thin footpath thin-walled property with seamless copper pipe, and the air-conditioning of wall thickness 0.20～0.25mm and refrigeration plant are imperative with the exploitation of seamless copper pipe.And traditional floating core head disc type drawing process production ultra-thin-wall copper pipe, restriction such as have that ovality is big, passage lengthening coefficient little (being not more than 1.45), copper pipe wall thickness instability, the disconnected pipe that stretches are serious.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of device of producing seamless copper pipe at above-mentioned deficiency of the prior art, this a kind of device of producing seamless copper pipe has the passage lengthening coefficient and reaches 1.6-2.0, the copper pipe wall thickness is stable, and disconnected characteristics of managing phenomenon can not occur stretching.
The technical solution adopted for the present invention to solve the technical problems is: it comprises spinning apparatus, prestretching external mold, prestretching trip core, cylindrical core print and plug die, described prestretching external mold, spinning apparatus and plug die are successively set on the copper pipe, described prestretching trip core and cylindrical core print are separately positioned in the copper pipe, and it is continuous by connecting rod, described prestretching trip core matches with the prestretching external mold that is arranged on the copper pipe outside, and described spinning apparatus is arranged on the copper pipe in the cylindrical core print outside.
Described spinning apparatus comprises steel ball and spinning ring, and described steel ball is arranged in the spinning ring, and steel ball is pressed on the copper pipe outer wall.
Characteristics such as a kind of device of producing seamless copper pipe of the present invention is compared with prior art, and have following outstanding beneficial effect: copper pipe can not be out of shape, and the passage lengthening coefficient reaches 1.6-2.0, and the copper pipe wall thickness is stable, can not occur stretching breaking managing phenomenon, and is easy to use.

The specific embodiment
Explain below doing with reference to 2 pairs of a kind of devices of producing seamless copper pipe of the present invention of Figure of description 1 and accompanying drawing.
A kind of device of producing seamless copper pipe of the present invention, its structure comprises spinning apparatus, prestretching external mold 5, prestretching trip core 6, cylindrical core print 3 and plug die 7, described prestretching external mold 5, spinning apparatus and plug die 7 are successively set on the copper pipe 4, described prestretching trip core 6 and cylindrical core print 3 are separately positioned in the copper pipe 4, and it is continuous by connecting rod 8, described prestretching trip core 6 matches with the prestretching external mold 5 that is arranged on copper pipe 4 outsides, and described spinning apparatus is arranged on the copper pipe 4 in cylindrical core print 3 outsides.
Described spinning apparatus comprises steel ball 2 and spinning ring 1, and described steel ball 2 is arranged in the spinning ring 1, and steel ball 2 is pressed on copper pipe 4 outer walls.
When producing copper pipe 4, high-speed electric expreess locomotive drives the spinning ring 1 and steel ball 2 rotation at a high speed of spinning apparatus, cylindrical core print 3 is by prestretching external mold 5 and prestretching trip core 6 common tube reducing location, steel pipe 4 moves, spinning apparatus carries out spinning to steel pipe 4, make copper pipe 4 external diameters reduce wall thickness reduction, carry out finishing to the outside dimension that requires by 7 pairs of copper pipes of plug die 4 again.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
