Type of stamping die

Stamping die in the punch, the metal or non-metal sheet separation or molding processing of the mold: called stamping die. . Stamping - is at room temperature,

A pressure processing method that uses a mold on a press to apply pressure to a material to cause it to separate or plastically deform, thereby obtaining the desired part.

      Classification stamping dies, generally we can simply put it into two, i.e., engineering and progressive die;

Engineering molds can be further divided into composite molds, drawing molds, and riveting molds. The structure and function of these molds are briefly described below.

Engineering model : Also called "single process model", it refers to a mold that can only complete one stamping process in one stroke of stamping . After this project is finished, it is necessary to remove the product from the mold manually or with a robot, and then put it into the next mold to continue production until the completion of the latter process of the mold. This kind of mold is simple to repair, but it takes time and labor to produce, requires more labor and time, and has a higher scrap rate.
     

Compound mold : The mold structure has compound cutting, compound drawing, etc. This kind of mold structure is slightly different from other engineering mold structures. The punch (also known as the male mold or punch) is designed in the lower mold, and the other several mold plates are the lower clamp plate (fixed punch punch), the lower stop plate and the lower stripper plate (outside release). The upper mold sequentially It is composed of a female mold (or knife-edge), an inner release plate and an upper backing plate, and the inner sleeve is hung on the upper backing plate with a contour sleeve, and is then pushed with a lever or a spring. For example, the composite mold used for blanking can be removed within 0.50 mm of the master mold. It must not be lower than the master mold, otherwise the mother mold edge can easily collapse or not be removed. The strength of the inner release must be large enough to lift the product out of the mold. Generally, if the material is thick, we have a nitrogen gas spring.
      

Continuous die: also known as " progressive die", refers to the die that completes two or more punching operations at the same time in the stamping process. This die is difficult to repair and requires experience. A wealth of fitter masters operate, but they are very efficient to produce. If they are fast, they can produce thousands of products in an hour, save labor and time, and have a lower scrap rate.
