Abstract

The invention discloses a plate strong deformation device and its technology, and relates to the field of metal material strong deformation processing. The device includes a frame, and a frame lower beam is arranged on the frame. The first traction hydraulic cylinder, the other end is equipped with a second traction hydraulic cylinder, a die is fixed between the first traction hydraulic cylinder and the second traction hydraulic cylinder, and the die is used to place blanks, The two ends of the billet are respectively fixedly connected with the first traction hydraulic cylinder and the second traction hydraulic cylinder; a frame upper beam is arranged above the die, and a vertically downward A hydraulic cylinder is provided, and the bottom of the piston rod of the hydraulic cylinder is fixedly connected with an upper pressure head. The present invention adopts the plate strong deformation process of the above-mentioned device, and through reciprocating bending and forming, the influence of uneven strain can be eliminated, so that the metal crystal grains can be evenly 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...
