Summary:The invention discloses an improved forge piece structure of an inner coupling of a ball cage type constant velocity universal coupling, which comprises a plurality of raceway grooves uniformly distributed on the spherical peripheral surface of the forge piece structure, bulges formed among the raceway grooves, and an upper circular concave hole and a lower circular concave hole positioned in the centers of the upper and lower end surfaces of the forge piece, the depth of the upper circular concave hole is larger than that of the lower circular concave hole, and a circle of annular structure corresponding to the depth of the lower circular concave hole is formed upwards on the lower end face of the forge piece structure. By means of the structural design of the forge piece, the contact face of a formed blank and a cavity can be reduced, then the forming load can be reduced, the die deformation amount is reduced, and the forming precision of a raceway groove is improved; the forming load is reduced, so that th
