TECHNICAL FIELD

[0001] The present application relates to the technical field of metal product finishing, in particular to a metal vacuum cup burr-free ring cutting equipment with smooth cut. BACKGROUND

[0002] A vacuum cup is a container for holding water, usually made of ceramic or stainless steel with a vacuum layer. It has a lid on top and is tightly sealed. The vacuum insulation layer can slow down the heat dissipation of the liquid inside, achieving the purpose of heat preservation. The vacuum cup developed from the vacuum bottle, and the heat preservation principle is the same as the vacuum bottle. In order to be convenient, people made the bottle into a cup. A metal vacuum cup is usually composed of an inner container, an outer shell and a vacuum layer. In the manufacturing process of the outer shell, a key step is to cut the cup body tube blank formed by punching and stretching to the designed length. One of the core steps in manufacturing a metal vacuum cup is to cut the long metal pipe into the appropriate length, and then go through the processes of inner and outer tube combination, vacuum extraction, cup body and cup bottom welding, etc. The flatness of the welding position and the smoothness of the cut are crucial to the sealing performance and heat preservation effect of the vacuum cup. When unqualified products are repaired, the tube body also needs to be accurately cut, which makes ring cutting an indispensable key process in the production of vacuum cups and has hard requirements for the quality of the cut.
