Abstract

The invention discloses a plate severe deforming device and a process thereof, and relates to the field of metal material severe deforming machining. The device comprises a frame, wherein a frame lower cross beam is arranged on the frame, one end of the frame lower cross beam is provided with a first traction hydraulic cylinder which is horizontally arranged, the other end of the frame lower crossbeam is provided with a second traction hydraulic cylinder, a female die is fixedly arranged between the first traction hydraulic cylinder and the second traction hydraulic cylinder, a blank is placed on the female die, and two ends of the blank are fixedly connected with the first traction hydraulic cylinder and the second traction hydraulic cylinder respectively; and a frame upper cross beam isarranged above the female die, hydraulic cylinders arranged vertically downwards are uniformly and symmetrically arranged on the frame upper cross beam, and an upper pressure head is fixedly connected to the bottom of a piston rod of each hydraulic cylinder. By adopting the plate severe deforming process of the device, the influence caused by uneven strain can be eliminated through reciprocatingbending forming, so that metal grains are uniformly refined.

Description

technical field [0001] The invention relates to the field of strong deformation processing of metal materials, in particular to a plate strong deformation device and a process thereof. Background technique [0002] Bending forming can effectively harden the material, and the preparation of high-performance metal sheets by reciprocating bending forming is a relatively effective strong deformation process. In the reciprocating bending process of the metal sheet, in addition to the bending deformation, it also produces a strong shear deformation and has a large shear strain. Due to the large amount of strain, the purpose of refining the material grains and hardening the material can be achieved. The traditional press bending process will cause uneven strain, easy to form defects, and the material is not easy to straighten. Contents of the invention [0003] The purpose of the present invention is to provide a plate strong deformation device and its technology to solve the p...
