Introduction All Stamping is a kind of pressure process method to apply pressure on material using dies fixed on punch to make it separate or deform and get the required work piece.
Stamping has been widely applied because of its advantages such as saving materials, high efficiency and being prone to product work piece of thin-wall.[1-4] More than 85% of total parts in daily living equipment, household electrical appliance and automobile are stamping work piece.
Stamping feeding is defined as sending the board material,bar material, wire material and semi finished articles to be processed to the work area of dies.

Tungsten oxide is a kind of multifunctional materials with excellent properties for gas sensing, electrochromic and photocatalytic applications.
Introduction Tungsten oxide is a type of attractive materials for hydrogen sensing for its high selectivity and sensitivity [1,2].
Therefore, controlling the nanostructure of the materials is of great importance to improve sensing performance [3].
In addition, the easy transformation between different phases is versatile to build other quasi-2D materials, which are attractive in relevant applications.
