Problems solved by technology

However, the disadvantage of this method is that the tear opening needs to be pulled apart manually, and the fingers are easily scratched by the sharp tear opening during the pulling process.
At the same time, this method has only one tear opening, and the crack will continue to extend during the process of pulling the tear open, reducing the effective use length of the copper tube and causing waste

Embodiment 1

[0018] Embodiment 1: a kind of small diameter square copper pipe tearing device, its structure is as figure 1 As shown: it includes a rectangular gland 1 inside, the rear end of the gland 1 is hinged to a cuboid liner 2, a splitting edge 5 is provided on both sides of the inner wall of the gland 1, and the gap between the two splitting edges 5 is The distance is greater than the width of the cuboid-shaped lining 2, and a spring 3 connects the gland 1 with the cuboid-shaped lining 2; the inner wall of the front end of the gland is provided with a sticky substance 4.

[0019] The sticky substance 4 is a self-adhesive.

[0020] The lengths of the two cutting edges 5 are the same.

[0021] The present invention also provides a method for using the small-diameter square copper pipe tearer of this embodiment, the steps are as follows:

[0022] A. Insert the cuboid liner 2 into the inner wall of the copper pipe to be cut;

[0023] B. Press the cover 1 down firmly, so that the two ...

Abstract

The invention relates to a small-aperture square copper pipe tearing device. The small-aperture square copper pipe comprises a gland of which the inside is rectangular, wherein the back end of the gland is hinged to a cuboid inner lining; both sides of the inner wall of the gland are provided with a cutting edge respectively; the distance between the two cutting edges is greater than the width of the cuboid inner lining; the gland is connected with the cuboid inner lining through a spring; the inner wall of the front end of the gland is provided with an adhesive substrate. By adopting tearing device disclosed by the invention, the problem of easiness in hurting fingers of a user during manual tearing of a small-aperture square copper pipe in the prior art is solved.

Description

technical field [0001] The invention relates to the field of copper pipe connection equipment, in particular to a small-diameter square copper pipe tearer and a method. Background technique [0002] Copper tube is a kind of non-ferrous metal tube, which has good ductility, plasticity and corrosion resistance, and is widely used in refrigeration equipment, heat exchange equipment and heating equipment. [0003] Among the common copper pipes, they are divided into copper round pipes and copper square pipes. [0004] When copper square tubes of the same caliber are welded and connected, one of the copper tube ports is often torn, and then another copper tube is inserted into the torn copper tube, and then welded. However, the disadvantage of this method is that the tear opening needs to be pulled apart manually, and the fingers are easily scratched by the sharp tear opening during the pulling process. At the same time, this method has only one tear opening, and the crack will...
