Description

Oval Copper Tube Forming Equipment {APPARATUS FOR MANUFACTURING OF PIPE HAVING AN ELLIPTICAL SECTIONAL SHAPE}

The present invention relates to a molding apparatus capable of easily and easily molding a circular pipe without an elliptical shape in an elliptical cross-sectional shape.

Generally, a heat exchanger used for a condenser and an evaporator in a cooling cycle is composed of a heat exchange pipe through which a heat medium flows, and a plurality of heat dissipation fins coupled to the heat exchange pipe.

The heat exchange pipe is constituted by a metal pipe having a sectional shape of a gauge, and is configured so that air flowing in the vicinity thereof and heat medium inside can mutually exchange heat. The radiating fin functions to widen the contact area between the air and the heat exchange pipe to increase heat exchange efficiency. In this case, the heat exchanger is generally configured to bend the heat exchange pipe in a substantially S-shape so that the middle portion thereof overlaps, and to connect the heat radiation fins to the heat exchange pipe at right angles, thereby reducing the size of the entire heat exchanger.

Therefore, when the fan disposed in front of the heat exchanger is operated, the air passes through the heat exchanger and heat-exchanges with the heat medium inside the heat exchange pipe.

However, since such a conventional heat exchange pipe has a circular cross-sectional shape and is peeled off with a turbulence of air at a rear angle of about 120 ° with respect to the direction of air flow, not only the resistance of air is increased, Air is not directly in contact with the heat exchange pipe on the rear side. Therefore, the heat exchanger using such a circular cross-section heat exchange pipe can not pass air well due to fluid resistance, and is not only stagnated in the heat exchanger but also has a problem that the area of direct contact of air with the heat exchange pipe is small, .

A method of manufacturing the heat exchange pipe by using a heat exchange pipe having an elliptical cross section instead of a circular cross section has been proposed. The heat exchange pipe having the elliptical cross section is firstly received from a predetermined manufacturer, In the lapping process, a method of heat treatment after drawing in an elliptical shape and cutting to a required length was used. However, in the case of such a method, when the heat exchange pipe is manufactured in an elliptical shape, it can be produced only when the drawing speed is slow, and since the heat exchange pipe after drawing is rigid, The production speed was delayed, and thus the supply of water was problematic.

Further, in order to solve the productivity deterioration, when the drawing speed is rapidly increased during the drawing process, the heat exchange pipe is warped in the longitudinal direction, and a heat exchange pipe having a uniform thickness throughout the entire length can not be produced. The problem has arisen that the productivity of the heat exchanger itself and the heat exchanger itself using the heat exchanger pipe are deteriorated as described above.

The present invention has been made to solve the above problems, the object of the present invention in forming an elliptical shape of the pipe having a circular cross-section, the automatic feeding of the long length of the pipe is wound by a predetermined length continuous While cutting, it is possible to easily elliptical shape without deformation of the elliptical shape to the user's desired shape, a number of processes are carried out continuously and elliptical at the same time without causing distortion of the tube during production or problems of reduced productivity It is to provide an elliptical copper tube forming apparatus capable of forming a plurality of tubes at the same time.

Other objects and advantages of the invention will be described below and will be appreciated by the embodiments of the invention. Further, objects and advantages of the present invention can be realized by the means and the combination shown in the claims.

The present invention as a means for solving the above problems, the tube uncoiler (10) is formed by winding the tube (P1) to be molded; A straight roller portion 20 for maintaining the origin and linearity of the pipe P1 conveyed by the pipe uncoiler portion 10; A first moving clamp unit (30) for transferring the tube (P1) through the linear roller unit (20) in one direction; A forming roller part 40 configured to discharge the pipe member P1 transferred through the moving clamp part into an elliptical shape; A second moving clamp unit 50 for transferring the elliptical pipe P2 discharged from the forming roller unit 40 in one direction; A cutting device (60) for cutting the elliptical pipe (P2) through the second moving clamp part (50); A discharge unit 70 for discharging the elliptical pipe P2 cut by the cutting device 60; Characterized in that consists of.
