| titleOfInvention | Necking device |
| abstract | The utility model discloses a necking device which comprises a driving oil cylinder, wherein the driving oil cylinder is sequentially connected with a connecting plate, a supporting seat, a supporting plate and a necking die, the connecting plate is fixedly connected with the driving oil cylinder, the connecting plate is fixedly connected with the supporting seat, the supporting plate is in sliding connection with the supporting seat, and the necking die is fixedly connected with the supporting plate; the supporting seat is connected with a first sliding rail through a first sliding block, and the first sliding rail is fixed to a rack of the connecting rod machining all-in-one machine. According to the necking devices provided by the utility model, a steel pipe is placed between the two necking devices, one end of the steel pipe faces one necking device, the other end of the steel pipe faces the other necking device, the two necking devices work simultaneously, and two ends of the steel pipe are simultaneously necked. The driving oil cylinder drives the connecting plate to drive the supporting seat to move along the first sliding rail, so that the necking die on the supporting plate is driven to perform necking on the copper pipe. |
