Abstract
The invention discloses a kind of multi-station progressive die and produce the method rushing recessed fat some part, first carry out fat point (1) die-cut station around, then carry out fat point (1) rush recessed station.The present invention adopt first die-cut rush recessed method again after, fat material around, due to cut, therefore will not be subject to the stretching of adjacent material when rushing and being recessed into shape, even the material that elongation is very low, it is also very regular that it rushes recessed SR sphere out.
Description
Technical field
The present invention relates to the multi-station progressive die Layout Design of a kind of part.
Background technology
At present, multi-station progressive die produces the mode rushing recessed fat some stamping for directly first carrying out rushing the recessed station fat point of generation on billot, is then punched out station again by the sharp processing of part out.This pattern type has a problem in that: when carrying out rushing recessed station, fat some adjacent material is in connection status, the recessed processing reality of rushing of material is stretch process, this can affect greatly for processing the relatively low ferrous metal of elongation percentage and stainless steel material: rushes recessed fat cracking, the problems such as SR spherical shape is irregular reveal, and this will directly affect the contact reliability of product.
Summary of the invention
The technical problem to be solved in the present invention: for the problems referred to above, the present invention recessed and die-cut station that liquidates on the stock layout of mould is adjusted.
Inventive technique scheme:
A kind of multi-station progressive die produces the method rushing recessed fat some part, first carries out the die-cut station of fat surrounding, then carry out fat point rush recessed station.
Described rushes recessed fat some part generally annular, and there is lobe the side of annular, at the recessed fat point of lobe upper punch.
Described multi-station progressive die produces the method rushing recessed fat some part, and its station stock layout step is as follows: one, punching station；Two, die-cut station；Three, rush recessed station；Four, bend station；Five, die-cut take mouth.
Beneficial effects of the present invention:
Adopt first die-cut rush recessed method again after, the material of fat surrounding, due to cut, therefore will not be subject to the stretching of adjacent material when rushing concave change shape, even the material that elongation is very low, it is also very regular that it rushes recessed SR sphere out.
Accompanying drawing illustrates:
Fig. 1 is design of part schematic diagram.
Fig. 2 is part side view.
Detailed description of the invention:
Such as figure, part to be processed is a contact chip containing contact, and it is annular generally, has two circular holes above, and annular is protruding to side and has a lobe, it is necessary at the recessed fat point 1 of lobe upper punch.
Using rustless steel billot to process this part, adopt multi-station progressive die to produce, its station stock layout step is as follows: one, punching station, rushes two holes on part；Two, die-cut station, the heart-shaped circular hole of die-cut part central authorities and the outward flange profile of part, stay in corresponding position, two holes and take mouth；Three, rush recessed station, at the recessed fat point 1 of lobe upper punch；Four, bend station, by part bending forming；Five, die-cut take mouth.
Claims (1)
1. a multi-station progressive die produces the method rushing recessed fat some part, it is characterized in that: described rushes recessed fat some part generally annular, there is lobe the side of annular, the recessed fat point (1) of lobe upper punch, first carry out fat point (1) die-cut station around, then carry out fat point (1) rush recessed work；Its station stock layout step is as follows: one, punching station, rushes two holes on part；Two, die-cut station, the heart-shaped circular hole of die-cut part central authorities and the outward flange profile of part；Three, rush recessed station, the recessed fat point (1) of lobe upper punch；Four, bend station；Five, die-cut take mouth.
