Patents by Inventor Xuejing Zhang

Xuejing Zhang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12275051
    Abstract: This application discloses a stamping device and a multi-lane shell stamping system, and the stamping device is used for simultaneous stamping of multiple shells, comprising a plurality of stamping die sets arranged in an array. Each stamping die set comprises an upper die and a lower die. The upper die is integrally formed, and the outer diameter of the upper die is larger than that of the lower die, and the bottom edge of the upper die forms a locating part for the curling of the shell to be processed. The present invention eliminates the movable locating cup, which can avoid the difficulty of mounting and dismounting the die due to the compact six-lane structure. At the same time, it adopts the method of directly increasing the diameter of the upper die, which not only avoids the mounting and dismounting of the locating cup, but also realizes the locating effect of the shell.

  • Patent number: 10642297
    Abstract: An online voltage adjustment circuit for a board power supply, where a first voltage division circuit is coupled in parallel to a first bias resistor, a second voltage division circuit is coupled in parallel to a second bias resistor, and a detection chip obtains an initial output voltage of the board power supply. Based on the initial output voltage and a preset voltage, a control chip controls a first switch on the first voltage division circuit to be on or off, and a second switch on the second voltage division circuit to be on or off. As a result, a feedback value of a feedback pin of the board power supply changes, and then an output voltage of the board power supply changes, thereby adjusting the output voltage of the board power supply.
