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

Abstract

The invention relates to a method for using a small-caliber copper round pipe tearer. The ripper mainly includes an arc-shaped gland inside. The front end of the gland is a smooth transition structure. The rear end of the gland is hinged with a cylindrical inner lining. The distance between the splitting blades is greater than the diameter of the cylindrical liner, and a spring connects the gland to the cylindrical liner. The ripper of the invention solves the problem in the prior art that fingers are easily injured when manually tearing small-diameter copper pipes.

Description

technical field [0001] The invention relates to the field of copper pipe connection equipment, in particular to a method for using a small-caliber copper round pipe tearer. 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 welding copper pipes of the same caliber, one of the copper pipe ports is usually torn, and then another copper pipe is inserted into the torn copper pipe, 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 continue to exten...
