Description

Technical Field

[0001] The utility model relates to the technical field of copper tube stretching, in particular to a copper tube stretching die. Background Technique

[0002] Copper tubes, also known as red copper tubes, are a type of non-ferrous metal tubes. They are seamless tubes formed by pressing or drawing. Copper tubes have the characteristics of being strong and corrosion-resistant, and thus have become the first choice for modern contractors in the installation of tap water pipes, heating, and refrigeration pipes in residential commercial housing. Copper tubes are the best water supply pipes.

[0003] In the copper tube processing and stretching process, pressure is applied to the head of the metal blank to enable the copper tube blank to pass through the die hole to obtain a product with the same shape, size, and model as the die hole. Traditional dies need to be fixed on the stretching die rack through bolts, and the replacement of the die is troublesome. Moreover, when adjusting the distance between adjacent two dies (the distance between dies needs to be adjusted according to the stretching requirements), it is also rather cumbersome. Therefore, a copper tube stretching die is proposed. Content of the Utility Model
