Example

[0041]The drawings taken with description make apparent to those skilled in the art how the invention may be embodied in practice. It should be understood that no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention.

[0042]It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements.

Abstract

A tube punching system for punching at least one hole into a tube, said system comprising: a punch, an external mold and a counter die. The mold and punch are positioned relative to each other such that the mold exerts a counterforce onto the tube when the hole is punched; and wherein the mold subsequently forms a collar as a result of the force applied by punch against the tube.

Description

FIELD OF THE INVENTION[0001]The invention relates to punching and collaring technology of tubes. More specifically, the present invention relates to tubes that may be used in solar heating, air conditioning and fluid conduction systems.BACKGROUND OF THE INVENTION[0002]Tubes that have a plurality of holes punched therein are in widespread usage as manifolds in many products such as solar heating panels.[0003]In the art, several systems are in use enabling punching of holes into the wall of a tube.[0004]In the art, an acceptable direction of punching is from the inner side of the tube to the outer side of the tube. Such a type of punching is hereinafter referred to as “punching a hole into a tube”.[0005]However, in order to use such tubes as manifolds, the punching of holes into the tubes should preferably generate a collar around each hole to facilitate brazing of other tubes onto the tube manifolds.[0006]The structure of the collar determines the quality of the brazing interface bet...
