  • Publication number: 20230286049
    Abstract: A device and a method for controlling a size of a molten pool in a wire and arc additive manufacturing process are provided. The device includes additive manufacturing equipment, a connecting device, bilateral gas flow devices and a CCD camera. By adjusting the connecting device, the bilateral gas flow devices and a welding gun have proper relative positions. The CCD camera is clamped on a rear side of the welding gun and matched with a proper optical filter to detect size information of the molten pool. In the additive manufacturing process, the bilateral gas flow devices and the welding gun keep moving synchronously, welding wires are conveyed to a designed position of a deposited layer by a wire feeding device, and bilateral gas flows can directly and synchronously act on a melting region. A flow controller is adjusted in real time according to the size of the molten pool.

  • Publication number: 20230017601
    Abstract: The present disclosure relates to a transition method and system from helical winding to hoop winding of composite fibers. The method includes: setting a slip coefficient, and performing iterative calculation forward from an iteration starting point according to an equation set of a winding angle and a center angle of rotation to obtain a winding angle at an iteration termination point; and if the winding angle at the iteration termination point is greater than a first preset angle, adjusting the slip coefficient corresponding to a cylinder body according to the first preset angle, extending a length of a helical winding transition section to a front equator, and starting the hoop winding at the front equator at the first preset angle to complete planning of the helical winding transition section.

  • Publication number: 20220381026
    Abstract: The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.

  • Patent number: 11319241
    Abstract: The invention discloses a composition for preparing glass, a glass article and a use thereof, and a glass article made from the composition. The glass article is preferably a glass substrate made from a composition with an M value of from about 1 to about 10 as calculated by the empirical equation: M=0.13×wt (B2O3)×wt (B2O3)+0.42×wt (CaO)+0.55×wt (MgO)+0.75×wt (SrO)?0.05×wt (Al2O3)×wt (Al2O3). A use of the glass article (especially the glass substrate) for manufacturing a display device is disclosed herein, wherein the glass article has better properties, such as lowered content of solid inclusions and gas inclusions, lowered thickness range and lowered warpage.
