Bulging die for titanium-alloy thin-walled complicated irregular annular workpieces

Abstract

The invention relates to a bulging die for titanium-alloy thin-walled complicated irregular annular workpieces. The bulging die comprises a core shaft, n brackets, n male dies, female dies and a base, wherein n sliding rails are uniformly distributed on the upper surface of the base, and all brackets are respectively embedded in all the sliding rails so as to form a circular assembly; the small-diameter end of the core shaft is located in the assembly and is fit with the internal surfaces of all the brackets; the n male dies are fixedly arranged on all the brackets respectively; each circular female die is formed through folding corresponding two semicircular female die clacks and sleeves the external surface of the corresponding male die; the internal surfaces of the female dies and the external surfaces of the male dies are workpiece forming faces. According to the bulging die, the forming of the irregular annular workpieces mainly relies on the plastic forming of a material, so that the surface wear resistance of parts is improved, the service lives of the parts are prolonged, and the material is saved; the accuracy of the annular workpieces can be corrected; during continuous repeated machining, the consistency of size and accuracy of the parts can be guaranteed.

Description

technical field [0001] The invention relates to the field of plastic processing, and relates to a titanium alloy thin-walled complex special-shaped annular workpiece bulging die. Background technique [0002] The commonly used manufacturing methods of special-shaped ring workpieces include rolling, bulging and cutting. The formed titanium alloy special-shaped ring is a thin-walled complex special-shaped ring workpiece. The inside and outside of the ring workpiece are special-shaped and the wall thickness is relatively uniform. It is difficult to form this type of annular workpiece due to the limitation of equipment and equipment, and for special-shaped annular workpieces with thin wall thickness, the rigidity is poor, and it is prone to instability during the rolling process, resulting in failure to form or the final roundness cannot be guaranteed, and Due to the influence of rolling process and equipment limitations, its dimensional accuracy is generally not high. Only when...
