Embodiment Construction

[0031] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0032] The high-deformation mold for sheet metal ring wave repeated drawing in the embodiment of the present invention is an axisymmetric cylindrical structure, such as Figure 1~3 As shown, it consists of ring wave upper die 9, ring wave lower die 7, guide post 8, guide sleeve 10, positioning stopper 1, positioning spring 2, positioning screw 3, nut 4, hexagon socket head cap screw 5, stopper 6 and other components composition. Among them, the ring-wave upper mold 9 and the ring-wave lower mold 7 are guided by the guide pillar 8 and the guide sleeve 10, directly participate in the forming of the plate, and draw the plate to the set waveform. The ring wave upper die 9 is fixed on the movable beam of the hydraulic press, and the ring wave lower die 7 is fixed on the worktable through the lower beam of the hydraulic press. The ring wave upper die 9 is a moving...

Abstract

The invention discloses a repeated plate ring wave drawing intense deformation die and technology. The die comprises an upper ring wave die body and a lower ring wave die body, wherein the upper surface and the lower surface of the upper ring wave die body are formed by a plurality of circles of concave-convex, continuous, alternative and coincident ring waves, and the upper surface and the lower surface of the lower ring wave die body are formed by a plurality of circles of concave-convex, continuous, alternative and coincident ring waves. The upper ring wave die body is connected with a movable cross beam of a hydraulic machine. The lower ring wave die body is fixed to a working table board. The upper ring wave die body is a movable die, and the lower ring wave die body is a fixed die. Two locating mechanisms arranged symmetrically in the radial direction are arranged at the upper end of the lower ring wave die body and can locate a plate. The upper ring wave die body and the lower ring wave die body are guided through a guide column and a guide sleeve which are arranged symmetrically in the axial direction, and directly participate in formation of the plate. By means of die closing, the plate is drawn to a set ring wave shape. According to the technology, through the die, repeated drawing is carried out for deforming and refining plate grain particles to enable the size of the grain particles to reach the micrometer level or the sub-micrometer level, finally, a flattening die is used for flattening the deformed plate, and a smooth plate is obtained. The die is free of restrictions of the size of the plate, the plate in the large size can be machined, and the comprehensive performance of the aspects such as physics, chemistry and mechanics of the plate are improved greatly.

Description

technical field [0001] The invention belongs to the field of material processing engineering, and relates to a mold for strong deformation of a plate and a process, in particular to a mold for strong deformation of a plate and a process for circular wave repeated drawing. Background technique [0002] Strong deformation of plates is currently the mainstream process for refining plate grains and optimizing plate properties. Typical processes include cumulative lap welding, high-pressure torsion, constrained molding, and repeated wrinkling-straightening methods. Most of these methods are limited by the size of the material, it is difficult to prepare large-sized products, or the prepared materials have strong anisotropy. Contents of the invention [0003] In view of the above existing problems, the present invention aims to provide a plate ring-wave repeated drawing strong deformation mold and process. Through the ring-wave mold, the plate grains are repeatedly formed and re...
