  • Publication number: 20230364879
    Abstract: Provided a device and method for paperboard stamping forming, relates to the technical field of paper material stamping forming equipment, comprising a punch-pin and a pressure-applying component, the pressure-applying component acting on a paperboard through a fluid medium; before the punch-pin carries out a stamping forming on the paperboard, the pressure-applying component pre-deforms the paperboard and a direction of the pre-deformation is opposite to a direction of the stamping forming; aiming to the current problem that the forming depth that is difficult to meet requirements resulted in the paperboard forming paper container limited by the deformation capacity of the paperboard, the forming depth of the paper container is improved by making the paperboard deform twice in opposite directions, bringing into play the deformation capacity of the full area of the paperboard, increasing the deformable amount of the paperboard, and reducing problems such as cracks and breakage in the forming process.

  • Publication number: 20220266391
    Abstract: The present invention provides a single-beam double-physical-effect coordinating and distributing method applicable to uniform laser shock and application thereof, and belongs to the technical field of laser shock effect control. The present invention does not stipulate the specific adjusting and distributing mean, and only provides a coordinating principle and method. The present invention gives a universal and systematic method for setting absorption layer feature parameters applicable to mass laser shock uniform peening under a liquid constraint condition, so as to facilitate the relevant technician to quickly obtain the liquid constraint laser shock processing technology conforming to a distribution proportion of its double physical effects, thereby being beneficial to development and application of the laser shock peening treatment, and therefore having the good actual application value.

  • Publication number: 20220234141
    Abstract: A method for processing surfaces of metal materials, and to a method for roughening a surface of a metal material by using a laser shock forming technology and an application thereof. According to the method, based on a pulse-laser-induced force effect, a micron-imprint mold and a nano-imprint mold are first prepared, and then the molds are used as a template to present surface microstructures of the imprint molds on a surface of a to-be-processed material. The method is simple and efficient. In addition, compared with a conventional method, a micron-structures and nano-structures can be quantitatively prepared on a surface of a metal material, and the surface roughness and the preparation scope are accurate and controllable and can be pre-designed.

  • Patent number: 11193183
    Abstract: The present invention relates to the technical field of material surface peening, and more particularly to an energy compensated equipower density oblique laser shock method. The method includes: acquiring a radius of curvature of a peening region of a part to be processed, and judging a range of a laser incident angle; determining laser parameters, such as laser pulse width, a spot diameter, and required laser energy under a vertical incidence condition; calculating the required laser energy at the minimum incident angle, and judging whether the energy falls within the technical indexes of a laser; and performing laser shock peening on the part by pulse laser beams with different energies. According to the present invention, the laser power or energy is compensated according to changes in the incident angle and the radius of curvature of the part to be processed.
