Description
Technical field
The invention belongs to mold design technical fields, progressive die and production more particularly to a kind of triangle sheet metal component
Technique.
Background technique
Currently, triangle sheet metal component generally uses single-stroke mould to be produced；Single punch-die refers to the disposable life in punching press
During production, the mold of a stamping procedure can be only done.This engineering is beaten be over after need it is artificial and with manipulator production
Product take out inside mold, are then put into inside the mold of the next stop and continue to produce, until the last one process of mold is beaten
Complete, entire product just calculates completion.Single punch-die saves product material, good debugging, but the more in process of production turnover of product, fortune
Defeated, storage and clamping, greatly reduce production efficiency；In addition single punch-die spends cost larger, and scrappage is high, stability also compared with
Difference.
So if producing this kind of triangle sheet metal component using progressive die, disadvantages described above will be greatly overcome；It is grading
Mould (being also the progressive die) is made of multiple stations, and each station is associated in order completes different processing, in the one stroke of punching machine
It is middle to complete a series of different punch process, after one stroke is completed, by punch press feeder according to a fixed step pitch
Material is moved forward, multiple stations can be completed on a secondary mold in this way, generally have punching, blanking, bending, trimming,
The stations such as stretch, have safe operation, be easy to automate, high velocity ram machine production can be used, reduce punching machine and site area and
The transport and warehouse for reducing semi-finished product occupy, the features such as productivity is high.But it is able to produce triangle sheet metal component in the industry at present
