Abstract
The utility model discloses a kind of fast changeable punch structure, it comprises fixed head backing plate, fixed head, small raft, little fixed head, pressing plate, punch; Together with described small raft is bolted on little fixed head, punch holddown groove and insertion end that punch inserts on little fixed head lean on small raft, and pressing plate is pressed in the short slot of punch sidewall and is bolted on little fixed head; Affixed small raft is together nested with in the holddown groove at fixed head and is bolted on fixed head backing plate together with the punch being fixed on little fixed head with little fixed head.Due to the utility model is first bolted on little fixed head with small raft together with, after punch is pushed down with pressing plate one by one, and use locked with bolts.Finally the whole group of part assembling put into holddown groove pre-processed on fixed head, with bolt, be fixed on fixed head backing plate.When need are changed product type, can conveniently whole group of punch be removed, reach quick-replaceable object.
Description
Technical field
The utility model relates to a kind of cold punching die, particularly relates to a kind of fast changeable punch structure.
Background technology
Along with lead frame market competition is increasingly violent, many frameworks manufacturer, for reducing die cost, often can produce the similar product common mode of several moneys.When need are changed product type.Only need just can reach variety renovation by changing the stamping-out punch-die of minority.As shown in Figure 1, it is upper that traditional punch retainer 1 ' is just simply plugged in punch 2 ' punch retainer 1 ', and by screw 3 ' locking, when need are changed product type, need control design drawing that corresponding punch is removed by eradicating, be loaded on corresponding new varieties punch, waste time and energy.
Utility model content
The purpose of this utility model is to provide a kind of replacing conveniently and fast changeable punch structure.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of fast changeable punch structure, and it comprises fixed head backing plate, fixed head, small raft, little fixed head, pressing plate, punch; Together with described small raft is bolted on little fixed head, punch holddown groove and insertion end that punch inserts on little fixed head lean on small raft, and pressing plate is pressed in the short slot of punch sidewall and is bolted on little fixed head; Affixed small raft is together nested with in the holddown groove at fixed head and is bolted on fixed head backing plate together with the punch being fixed on little fixed head with little fixed head.
Adopt after such scheme, because the utility model is taked the mode of integral replacing, the punch design that need are changed is in same position, together with first little fixed head being bolted on small raft, after punch is pushed down with pressing plate one by one, and use locked with bolts.Finally the whole group of part assembling put into holddown groove pre-processed on fixed head, with bolt, be fixed on fixed head backing plate.When need are changed product type, can conveniently whole group of punch be removed, reach quick-replaceable object.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 commonly uses male die fixing structure schematic diagram;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, the utility model is a kind of fast changeable punch structure, and it comprises fixed head backing plate 1, fixed head 2, small raft 3, little fixed head 4, pressing plate 5, punch 6.
Described small raft 3 is fixed together by bolt 91 with little fixed head 4, punch holddown groove 41 and insertion end that punch 6 inserts on little fixed head 4 lean on small raft 3, and pressing plate 5 is pressed in the short slot 61 of punch 6 sidewalls and is fixed on little fixed head 4 by bolt 92; Affixed small raft 3 together and little fixed head 4 are nested with in the holddown groove 21 at fixed head 2 and by bolt 93 and are fixed on fixed head backing plate 1 together with being fixed on punch 5 on little fixed head 4.
Assembly method of the present utility model:
First little fixed head 4 and small raft 3 are fixed together by bolt 91, after punch 6 is pushed down with pressing plate 5 one by one, and lock with bolt 92.Finally the whole group of part assembling put into holddown groove pre-processed on fixed head 2 21, with bolt 93, be fixed on fixed head backing plate 1.When need are changed product type, can conveniently whole group of punch be removed, reach quick-replaceable object.
Emphasis of the present utility model is just: punch and small raft, little fixed head are assembled into one group in advance.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
