Abstract
The utility model provides a punching compound die with four bent corners, which comprises a punch-die, a punching terrace die, a curve terrace die and a curve die, wherein the curve die is installed on a punching terrace die fixed plate, a cavity of the curve die is internally provided with an elastic element, the curve terrace die and the punch-die, the punching terrace die is fixed on the punching terrace die fixed plate and sequentially penetrates through the elastic element and a bottom plate of the curve terrace die so as to be opposite to the protruding part of the punch-die, the curve terrace die is opposite to the concave part of the punching-die, and the outer side surface of the bottom plate of the curve terrace die is matched with the inner side surface of the curve die. After floating curve terrace die is adopted, two times of U-shaped bending and punching are guaranteed to carry out sequentially, when in punching, bending and deformation are avoided, therefore, the accuracy of an upper hole of piece to be bent and the hole distance is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of four angular distortion punching hole composite die structures.
Background technology
When the hole on the crooked punching part and pitch of holes required precision were higher, its punching production had certain complexity, crooked again its precision of control that is difficult to after the first punching.
Therefore, need a kind of four angular distortion punching hole composite die structures of design.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of four angular distortion punching hole composite die structures are provided.
The purpose of the utility model realizes through following technical scheme:
Four angular distortion punching hole composite die structures; It is characterized in that: comprise punch-die, piercing punch, crooked punch and crooked die; Crooked die is installed on the piercing punch fixed head; Arrange flexible member, crooked punch and punch-die successively in the die cavity of crooked die; Piercing punch is fixed on the piercing punch fixed head, and to pass the protuberance of base plate and punch-die of flexible member and crooked punch successively relative, and it is relative that crooked punch and punch-die recessed goes out portion, and the plate outer side face of crooked punch cooperates with the medial surface of crooked die.
Further, four above-mentioned angular distortion punching hole composite die structures, wherein, said piercing punch fixed head is fixed on the piercing punch backing plate.
The substantive distinguishing features of the utility model technical scheme is mainly reflected in progressive:
Through adopting floating type crooked punch, guaranteeing successively that twice U type is crooked carries out with punching successively, and punch process is carried out after four angular distortions, and assurance does not occur bending and deformation in the time of punching, thereby effectively guarantees the precision in hole and pitch of holes on the bool.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Fig. 1: the organigram of the utility model.
The specific embodiment
As shown in Figure 1; Four angular distortion punching hole composite die structures; Comprise punch-die 1, piercing punch 3, crooked punch 2 and crooked die 4, crooked die 4 is installed on piercing punch fixed head 6, arrange flexible member 7, crooked punch 2 and punch-die 1 in the die cavity of crooked die 4 successively; Piercing punch 3 is fixed on the piercing punch fixed head 6, and to pass the protuberance of base plate and punch-die 1 of flexible member 7 and crooked punch 2 successively relative; It is relative that crooked punch 2 and punch-die 1 recessed goes out portion, and the plate outer side face of crooked punch 2 cooperates with the medial surface of crooked die 4, and piercing punch fixed head 6 is fixed on the piercing punch backing plate 5.
In sum; The utility model designs a kind of four novel angular distortion punching hole composite die structures, and through adopting floating type crooked punch, assurance twice U type bending successively and punching are carried out successively; Eliminate diastrophic generation during punching, thereby effectively guarantee the precision in hole and pitch of holes on the bool.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. four angular distortion punching hole composite die structures; It is characterized in that: comprise punch-die, piercing punch, crooked punch and crooked die; Crooked die is installed on the piercing punch fixed head; Arrange flexible member, crooked punch and punch-die successively in the die cavity of crooked die; Piercing punch is fixed on the piercing punch fixed head, and to pass the protuberance of base plate and punch-die of flexible member and crooked punch successively relative, and it is relative that crooked punch and punch-die recessed goes out portion, and the plate outer side face of crooked punch cooperates with the medial surface of crooked die.
