[0002] Copper tube is a kind of non-ferrous metal tube. It is often used in the manufacture of heat exchange equipment, and is also used to assemble low-temperature pipelines in oxygen equipment. Copper tubes with small diameters are often used to transport pressured liquids (such as lubrication systems, oil pressure systems, etc.) etc.) and pressure measuring tubes used as instruments, etc., the outer convex point is mainly used in the butt joint assembly of copper tubes, and the inner diameter of the outer base metal is larger than the outer diameter of the inner base metal, it is used to limit the depth of the insertion to ensure the welding of components The size meets the design requirements. At present, the processing of the outer bumps of the copper tube uses a micro-stamping machine tool as the body. The punching power meets the needs of bump processing, but the power comes from the motor-driven cam structure, and the downward punching depth is difficult to control. As a result, the mandrel used to insert the copper tube to be processed often breaks, resulting in a decrease in production efficiency and an increase in processing costs. At the same time, the existing processing devices all need to socket the copper tube on the mandrel, and then realize the production of bumps. The method It is more traditional, and at the same time, the production of bumps cannot be automated, the accuracy is low, and the efficiency of copper tube production is low. Therefore, we propose a copper tube external bump processing device for air conditioners.
