The utility model discloses theory of operation and working process of mould:
the workpiece is placed on the lower die, the upper die does up-and-down oscillating motion along with the punch of the special-shaped curved surface rapid forming machine, and after the upper die is in downward contact with the workpiece, the striking force of the formed workpiece is generated between the upper die and the lower die. When the upper and lower dies are subjected to a vertical hitting force, the upper force transmission ring 6 and the lower force transmission ring 16 generate a horizontal component force in the horizontal direction while being subjected to a vertical force, the horizontal component force drives the upper shrink disk 7 and the lower shrink disk 18 to stretch outwards, and since the upper die sheet 9 and the upper shrink disk 7 are fixedly connected and the lower die sheet 19 and the lower shrink disk 18 are fixedly connected, the upper die sheet 9 and the lower die sheet 19 simultaneously drive the material of the workpiece to stretch outwards, so that the purpose of outwards deforming the workpiece is achieved. In order to enable the upper die piece 9 and the lower die piece 19 to securely grip the workpiece without slipping during deformation of the workpiece, pointed teeth are formed on their surfaces.
Since the magnitude of the horizontal force required for deformation is kept in constant proportion to the vertical striking force provided by the shaped curved surface rapid prototyping machine, if the vertical striking force is increased, the horizontal force of the formed workpiece is increased in synchronization. The greater the tendency of the material of the workpiece to flow outwardly under the action of this horizontal force, and thus the workpiece is forced to bend outwardly, producing the deformation required by the user. The striking force is gradually increased, and the deformation of the workpiece is continuously increased until the deformation meets the requirement.
