Stamping is a forming process that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to produce plastic deformation or separation to obtain workpieces of the desired shape and size (stampings). The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. So what are the technical requirements of hardware stamping parts?
Stamped parts have the following technical requirements in the process of production, storage and transportation.
1、Size and shape: The size and shape of the stamping parts should be basically in accordance with the product design drawings and technical documents of the stamping parts.
2、Burr: The stamping parts which are sheared or blanked will generally have burr, and then they need to be polished according to "Burr Height of Stamping Parts".
3、Surface quality: Except for punching and cutting, the surface condition of the stamped parts is required to be the same as that of the plate used, and only small surface area unevenness and slight hair pulling can appear in the process of forming, and at the same time, it cannot affect the quality of the finished products in the next process into the assembly.
4、Heat treatment: After forming and welding of stamping parts, heat treatment is generally not required.
5、Punching and cutting surface: The condition of punching and cutting surface is not specified.
6、Supply good: The supply of stamping parts should ensure their basic quality status and conform to the product chart and inspection card of stamping parts.
