Abstract
The invention discloses a method for producing a concave-punching fat point part through a multi-station progressive die. The method includes the steps of conducting station punching around a fat point (1), and then conducting station concave-punching of the fat point (1). After the method of conducting punching first and then conducting concave-punching is adopted, materials around the fat point are cut off, and therefore the fat point can not be stretched by the materials around during concave-punching forming; even for the materials with the low elongation percentage, the SR spherical face formed through concave-punching is neat.
Description
Technical field
The present invention relates to a kind of multi-station progressive die Layout Design of part.
Background technology
At present, the mode that recessed fat some stamping rushed in multi-station progressive die production produces fat point for directly first rush recessed station on billot, and then carries out die-cut station by the sharp processing of part out.The problem of this stock layout mode is: when rushing recessed station, around fat point, material is in connection status, material to rush recessed processing actual be stretch process, this can affect greatly for lower ferrous metal and the stainless steel material of processing percentage elongation: rush recessed fat some 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's recessed and die-cut station that liquidates on the stock layout of mould is adjusted.
Invention technical scheme:
Multi-station progressive die is produced a method of rushing recessed fat some part, first carries out fat point die-cut station around, then carries out the recessed station of rushing of fat point.
Described to rush recessed fat some part whole be annular, and a side of annular has lug boss, at the recessed fat point of lug boss upper punch.
Described multi-station progressive die is produced the method for rushing recessed fat some part, and its station stock layout step is as follows: one, and punching station; Two, die-cut station; Three, rush recessed station; Four, bending station; Five, the die-cut mouth of taking.
Beneficial effect of the present invention:
Adopt first die-cut punching again after recessed method, fat some material around, due to cut, therefore can not be subject to the stretching of material around when rushing recessed distortion, even the very low material of elongation, it is also very regular that it rushes recessed SR sphere out.
accompanying drawing explanation:
Fig. 1 is design of part schematic diagram.
Fig. 2 is part side view.
the specific embodiment:
As figure, part to be processed is a contact chip that contains contact, and its integral body is annular, has two circular holes above, and annular is to a side projection and have a lug boss, need to be at the recessed fat point 1 of lug boss upper punch.
With stainless steel billot, process this part, adopt multi-station progressive die to produce, its station stock layout step is as follows: one, and 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 and take mouth in corresponding position, two holes; Three, rush recessed station, at the recessed fat point 1 of lug boss upper punch; Four, bending station, by part bending forming; Five, the die-cut mouth of taking.
