Technical Field
The invention relates to vacuum cup processing equipment, in particular to a vertical flanging machine.
Background
In order to prevent the cup mouth of the metal thermos cup from scratching a user, the liner of the thermos cup needs to be turned outwards, and then the outer side of the liner is sleeved with a shell.
The conventional vacuum cup adopting the flanging back-arc port welding process has the problems that the flanging outer diameter of the opening of the liner is larger than the opening inner diameter of the shell after the opening is spirally contracted, and the liner cannot be sleeved into the shell to be matched with the opening for welding, so that the liner is sleeved into the shell, then the opening of the liner is flanged, and finally the opening is welded. For the above process, a currently commonly adopted flanging machine is a horizontal flanging machine, such as a stainless steel cup rim flanging machine with a patent number of 202022343064.5.
