A drive machinery for spring forming apparatus includes: servomotors (1), decelerating boxes (2), transmission devices, camshaft units, cam gears (6) and forming slide plates (8). Each group of servomotor connects with a decelerating box, which is connected with a transmission device. Two synchro-gears and a synchronic strap compose each transmission device. And the two synchro-gears can keep synchronic by the synchronic strap. A camshaft facility and a cam gear are connected with each synchro-gear. Through the cycling of the servomotor (1), two cam gears (6) can be turned simultaneously and then drive two groups of proximate machining slideplates (8). As driving two groups of proximate machining slide plates (8) by each group of servomotor, eight groups of machining slide plates can be drived by only four groups of servomotors. Additionally, even in the process of producing different springs, the shape and the position of the cam gear need not to be adjusted. Therefore, the cost of the machine can be reduced, and the productivity can be improved. |
