RT Journal Article SR Electronic A1 Yimin, Liu A1 Jie, Wang T1 Design and Calculation of Multi-angel and Stepping Transmission of Sucker Rod Forging JF Manufacturing Technology Journal YR 2014 VO 14 IS 4 SP 650 OP 657 DO 10.21062/ujep/x.2014/a/1213-2489/MT/14/4/650 UL https://journalmt.com/artkey/mft-201404-0025.php AB The paper puts forward structure design and parameter analysis of the multi-angle and stepping transmission device, and this paper focuses on design and analysis of the multi-angle steering parts in the device. According to mathematical calculation and simulation analysis, the parts size of steering component is simulated and designed by the double cam-linkage mechanism. Though the design of these critical components of the steering device, the rods can be rotated in the specified angle (45° and 90°) by their relative motion without any external force, and the steering device is simulated by SolidWorks Motion. The results show that the multi-angle and stepping transmission device realizes the upset forging process requirements, improves the mechanization level of the sucker rod forging. The device will be used for the rod head machining operation in narrow space in automatic production line, and it also can be extended to other cylindrical rod's multi-angle and multi-position automatic machining operation.
