Abstract
The utility model discloses a novel compound punching die which comprises an upper die base plate, an inner dropping block returning spring, an inner dropping block returning guide post, a connecting rod, an inner dropping block, a trimming die, a punch, a forged piece and a lower die block. The inner dropping block returning guide post and the connecting rod are arranged below the upper die base plate, the inner dropping block returning guide post is provided with the inner dropping block returning spring and penetrates the inner dropping block and then is connected with the trimming die, the connecting rod is also connected with the trimming die, the trimming die is located on one side of the inner dropping block, the punch is located on the other side of the inner dropping block, the forged piece is located below the inner dropping block, the lower die block is located below the forged piece, a first gap is reserved between the inner dropping block and the punch, a second gap is reserved between the inner dropping block and the trimming die, the length of the first gap and the length of the second gap are smaller than 2 mm, and the trimming die and the punch are guided by the inner dropping block. The hole site degree and the hole flatness precision of the forged piece punched by the novel compound punching die are higher and can be suitable for the forged piece having high-precision technical requirements.
Description
Technical field
The utility model relates to a kind of NEW TYPE OF COMPOSITE blanking die.
Background technology
The die-cut forging position degree of conventional composite blanking die, flatness low precision, often need machine to add and auxiliary can reach specification requirement, for reducing this machined, fills order and design this NEW TYPE OF COMPOSITE mould.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of die-cut forging hole and hole location, the flatness precision in hole own is higher, can be applicable to the NEW TYPE OF COMPOSITE blanking die that high precision technology requires forging.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of NEW TYPE OF COMPOSITE blanking die, comprise baffle plate, interior de-piece return spring, interior de-piece return guide pillar, connecting rod, interior de-piece, edger, drift, forging and lower module, described upper baffle plate below is provided with interior de-piece return guide pillar and connecting rod, described interior de-piece return guide pillar is provided with interior de-piece return spring, after running through interior de-piece, described interior de-piece return guide pillar is connected with edger, described connecting rod is also connected with edger, described edger is positioned at a side of de-piece, described drift is positioned at the opposite side of de-piece, described forging is positioned at de-piece below, described lower module is positioned at forging below, between described interior de-piece and drift, be separated with gap one, between described interior de-piece and edger, be separated with gap two, the length in Yi He gap, described gap two is all less than 2mm, it is guiding that described edger and drift all be take interior de-piece.
As preferably, described gap one is 0.1mm.
As preferably, described gap two is 0.1mm.
The beneficial effects of the utility model are: owing to being provided with lower module, interior de-piece and interior de-piece return spring, can avoid displacement at the downward forging of pushing down when die-cut of patrix, also collocation has edger and drift simultaneously, it is guiding that described edger and drift all be take interior de-piece, therefore downward when die-cut, drift and edger are gone out gross weight and overlap downwards through interior de-piece guiding, thereby realize whole die-cut process, and less Yi He gap, gap two also further makes forging position degree, the flatness precision gone out higher.
Accompanying drawing explanation
Fig. 1 is the plane of a kind of NEW TYPE OF COMPOSITE blanking die of the utility model.
The specific embodiment
Consult shown in Fig. 1, a kind of NEW TYPE OF COMPOSITE blanking die, comprise baffle plate 1, interior de-piece return spring 2, interior de-piece return guide pillar 3, connecting rod 4, interior de-piece 5, edger 6, drift 7, forging 8 and lower module 9, a whole set of compound die assembling be take interior de-piece 5 as benchmark assembling, described upper baffle plate 1 below is provided with interior de-piece return guide pillar 3 and connecting rod 4, described interior de-piece return guide pillar 3 is provided with interior de-piece return spring 2, after running through interior de-piece 5, described interior de-piece return guide pillar 3 is connected with edger 6, described connecting rod 4 is also connected with edger 6, described edger 6 is positioned at a side of de-piece 5, described drift 7 is positioned at the opposite side of de-piece 5, described forging 8 is positioned at de-piece 5 belows, described lower module 9 is positioned at forging 8 belows, between described interior de-piece 5 and drift 7, be separated with gap one (not shown), between described interior de-piece 5 and edger 9, be separated with gap two (not shown), the length in Yi He gap, described gap two is all less than 2mm, de-piece 5 and edger 6 in conventional composite blanking die, gap length between interior de-piece 5 and drift 7 is generally in 2mm left and right, this larger gap can cause going out forging position degree, flatness precision is lower, described edger 6 and drift 7 all be take interior de-piece 5 as guiding, drift 7 and edger 6 cannot before and after, left and right skew.
Described gap one is 0.1mm, and less gap can make to go out forging position degree, flatness precision is higher.
Described gap two is 0.1mm, and less gap can make to go out forging position degree, flatness precision is higher.
The blank forged piece 8 forging from swaging die is placed on counterdie 9 and fixes, upper baffle plate downward when die-cut in de-piece 5 by spring 2, first push down forging 8 and allow it not be shifted, die-cut downwards again, drift 7 and edger 6 are gone out gross weight and overlap downwards through interior de-piece 5 guiding, thereby realize whole die-cut process; And that interior de-piece 5 is pushed down forging 8 is motionless, between interior de-piece 5 and drift 7, edger 6, gap is less, and forging position degree, the flatness precision gone out are higher.
The beneficial effects of the utility model are: owing to being provided with lower module, interior de-piece and interior de-piece return spring, can avoid displacement at the downward forging of pushing down when die-cut of patrix, also collocation has edger and drift simultaneously, it is guiding that described edger and drift all be take interior de-piece, therefore downward when die-cut, drift and edger are gone out gross weight and overlap downwards through interior de-piece guiding, thereby realize whole die-cut process, and less Yi He gap, gap two also further makes forging position degree, the flatness precision gone out higher.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
