| description | The invention discloses a quenching and tempering method for splines of bimetal cylinder bodies of a hydraulic plunger pump and motor, and belongs to the technical field of machining. Residual heat isutilized to carry out hardening and tempering heat treatment in a bimetal casting process. Spline hardening and tempering are carried out in a cooling process. The method comprises the following specific operation steps that after heat preservation treatment of bimetal cylinder bodies, heated and molten according to a casting technology, of the hydraulic plunger pump and motor is finished, a steel base body and a molten copper alloy are conveyed to a cooling area device, and when the temperature is reduced to 840-880 DEG C, a hardening and tempering medium and compressed air are introduced into spline parts at the same time for cooling and hardening and tempering, wherein the hardening and tempering time is 5-10 min; the spline parts are conveyed to a designated position for air-cooling to normal temperature and |
