Combined type fan cover die capable of preventing workpiece from deforming

The utility model discloses a combined type fan cover mould for preventing workpiece deformation, which comprises a main body, a mounting mechanism and a feeding mechanism, the mounting mechanism is arranged in the middle of the upper part of the main body, and the feeding mechanism is arranged in the middle of the upper part of the mounting mechanism. Compared with an existing device, the combined type fan cover die capable of preventing the workpiece from deforming can drive the lower die bases to move through the first motor, the other side can be replaced in time after one lower die base is machined, and therefore the machining efficiency can be improved, meanwhile, the machined lower die base is moved to the other side to facilitate die stripping, and through a positioning rod and a positioning sleeve, the machining efficiency is improved. According to the device, the position of the die can be positioned during downward pressing work, deformation of an object during machining due to expansion and disloc
