Machine for forming T-shaped tubular components using a forming material insert

摘要

A machine for forming T-shaped tubular components comprises a plurality of successive stations. A tubular blank having a forming material insert therein is positioned within a T-shaped die in a first station. A bulge is formed in the blank as force is applied to the ends or runs of the blank and the insert from opposing punches. Once the bulge or outlet of the T-shaped component is formed, a hollow pointed punch is driven through the outlet to open it. All of the punches are removed, the die is opened and the partially formed T-shaped component is transferred to a second station for cleaning. A broach is driven into one of the runs of the component while a punch is driven into the outlet. The forming material in the outlet is driven towards the runs of the component by the punch so that it is carried out the other one of the runs by the broach together with the forming material in the runs. The punch and broach are removed and the component is transferred to a third station for sizing one or more of the ends of the component. The component is then transferred to a fourth station for further sizing of one or more of the ends of the component. The T-shaped component is thus formed and removed from the machine. The machine is configured so that each station performs its respective forming operation on different components substantially at the same time so that components pass through the stations in succession.
