The invention discloses an external spline shaft cold extrusion precision forming device and a forming method, comprising a box body, a spline shaft and a control system, the top of the box body is fixedly connected with a fixing block by fixing bolts, and the fixing block There is a processing cavity inside, the front of the fixed block is provided with a spline shaft groove, the spline shaft is located inside the spline shaft groove, and the bottom of the box cavity is provided with a sliding groove, and the sliding groove The top of the cavity is slidably connected with a motor casing, and the inner surface of the motor casing is fixedly connected with a rotating motor. The present invention relates to the technical field of spline shafts. The external spline shaft cold extrusion precision forming device and forming method, by setting the mounting block at the output end of the second servo electric cylinder, and cooperating with the cutter on the mounting block, the groove can be further refined, and the structure can be used for The spline shaft is finished, which can ensure the precision while ensuring the bearing capacity, and further improve its practicability.
Description
technical field [0001] The invention relates to the technical field of spline shafts, in particular to an external spline shaft cold extrusion precise forming device and a forming method. Background technique [0002] The spline shaft is a kind of mechanical transmission. The flat keys, semi-circular keys and oblique keys have the same functions, and they all transmit mechanical torque. It rotates synchronously with the shaft, and while rotating, some can also slide longitudinally on the shaft, such as gearbox shifting gears, etc. The spline shaft is divided into two types: rectangular spline shaft and involute spline shaft. The rectangular spline shaft in the shaft is widely used, while the involute spline shaft is used for large loads, high centering accuracy, and large-scale connections. The rectangular spline shaft is usually used in aircraft, automobiles, tractors, machine tools. Manufacturing, agricultural machinery and general mechanical transmission and other device...
