The power press stamping molds/tools are including: 1. Progressive die,
2. Stage mold (single stage mold),
3. Transfer mold (with transfer system)
What is the difference between progressive die, stage mold and transfer mold?
Continuous die (also known as progressive die, step die) refers to the press in a stroke, in turn in several different positions, at the same time to complete a number of procedures of the die. Blanking parts are gradually formed in the continuous die, continuous forming is a process method of process concentration, can make the edge cutting, incision, groove cutting, punching, plastic deformation, blanking and other processes in a mold to complete. According to the actual needs of stamping parts, according to a certain order arranged a number of stamping processes (called in the progressive die station) for continuous stamping. It can not only complete the blanking process, but also complete the forming process, and even the assembly process, many complex stamping parts that need multi-process stamping can be completely formed on a die, which provides favorable conditions for high-speed automatic stamping. It can be seen
that the continuous die is a kind of punching die with many working stations and high efficiency.
An engineering mold (single working procedure mold/single-stage mold) is a mold with a single working position and a single working procedure. It is characterized by a simple mold structure and requires manual or robotic arm assistance. As a result, the production efficiency is relatively low, and it is mainly used for the production of workpieces with small batch sizes and low precision requirements. Due to the low cost of engineering molds and the low tonnage requirement for punch presses, the engineering mold approach is often preferred when designing molds. However, with the continuous increase in costs, engineering molds are gradually being replaced by continuous molds or transfer molds.
Multi-station transfer mold, generally refers to the use of special multi-station punch, by a number of engineering mold with a certain process connection according to the process sequence installation, a kind of mold delivered by the manipulator. The most important characteristics of the multi-station transfer die (1) in the use of multi-station punch;(2) Each station is a complete engineering model to complete a specific process. Each engineering mold (single station-mold)
has a certain connection, each station mold can be adjusted independently, and the adjustment is generally not restricted by the front and back mold;(3) transmission mode: mechanical hand delivery.
