US Patent 7624613 Terminal crimping machine

A terminal crimping machine includes a frame. An accommodating board is located on the frame and defines recesses unfolding symmetrically. The junction of the recesses defines an aperture running through the accommodating board. Drifts are slidably received in the recesses of the accommodating board respectively. Each of the drifts has a bar which protrudes rearward from a back surface of the drift. A propelled member rotationally configured at the back of the accommodating board defines cavities distributing symmetrically, and each cavity extends continually from outside to inner. The cavities slidably receive the bars of the drifts respectively. A driven mechanism, mounted on the frame, connects with the propelled member.
