Abstract
A feed precise locating device of the progressive die of an elastically floated cone pilot consists of a cushion plate, a fixing plate, the cone pilot, a discharge plate, a piercing punch and a piercing die; the pilot surface of the cone pilot is a cone; the head part of the cone pilot is a hemisphere; the cone pilot is fixed on the fixing plate; the top part of the cone pilot is provided with a spring; the other end of the spring is connected with the cushion plate. The device of the invention has the advantages of high feed locating precision of the progressive die, long service life of the cone pilot, simple structure and easy implementation, in particular to the advantage that the using effect is better when the thickness of a metal plank stuff is larger; the invention is widely applied to a progressive die formed by adopting cold punching shaping in large precise automobile parts.
Description
(1) technical field
The present invention relates to a kind of progressive die feeding precision positioning device of taper seat pilot pin of progressive die locating unit, particularly a kind of elastic floating.
(2) background technology
" progressive die " is called " progressive die " or " progressive die " again, is a kind of mould the most complicated in the cold stamping shaped mould of sheet metal, and it is in the one stroke of forcing press, on the diverse location of mould, finish two above stamping procedures.Progressive die will seek out high-precision product, just must guarantee the feeding positioning accuracy of metal blank in progressive die.The feeding positioning accuracy is high more, and the precision of product is high more.At present, the locating unit in the progressive die all adopts single-stage punching structure, and promptly metal blank during feeding, is cooperated by piercing punch and punching concave die earlier in progressive die, goes out the correcting hole on metal blank, and metal blank is sent a step pitch forward to then; After sending to, in the correcting hole on the pilot pin insertion metal blank, with the metal blank correcting, so that eliminate the site error that produces when progressive die is sent metal blank to.Adopt the progressive die locating unit of above-mentioned single-stage punching, its feeding positioning accuracy depends mainly on the precision in correcting hole, but the correcting hole precision of common punching mode can only reach IT8～IT9 level, can not satisfy the needs of high accuracy product far away; When adopting the single-stage punching in addition, the correcting hole surface of going out on metal blank is of poor quality, and its section can produce burr and rough shear fracture, can scratch the correcting surface of pilot pin when cooperating with pilot pin, not only reduce the correcting precision, and can influence the service life of pilot pin greatly.
(3) summary of the invention
The objective of the invention is at above-mentioned existing problems, the progressive die locating unit of taper seat pilot pin of the elastic floating of a kind of feeding positioning accuracy height, pilot pin long service life, simple in structure and easy enforcement is provided.
Technical scheme of the present invention
A kind of progressive die feeding precision positioning device of taper seat pilot pin of elastic floating, form by backing plate, fixed head, taper seat pilot pin, stripper, piercing punch and punching concave die, it is characterized in that: the correcting face of taper seat pilot pin is a pyramid type, and the head of taper seat pilot pin is a dome-type; The taper seat pilot pin is fixed on the fixed head, and spring is equipped with at the top of taper seat pilot pin, and the other end and the backing plate of spring join.
A kind of progressive die feeding precision positioning device of taper seat pilot pin of above-mentioned elastic floating is characterized in that: the length of pyramid type correcting face is 2mm～10mm, and its coning angle is 0.1 °～1 °.
Advantage of the present invention is 1) taper seat pilot pin and correcting hole realize that no gap cooperates: there is the fit clearance about 0.04mm～0.1mm between common cylinder type pilot pin and the correcting hole, limited the feeding positioning accuracy, and enter into the certain depth in correcting hole when pyramid type correcting face after, its pyramid type correcting face will closely contact with the correcting hole, the taper seat pilot pin realizes that with the correcting hole no gap cooperates, thereby improved the feeding positioning accuracy, after taper seat pilot pin and correcting hole have realized that no gap cooperates, mould also can continue to press down, and at this moment the taper seat pilot pin keeps its position and makes the unlikely damage of mould by the compression of spring; 2) improved service life of pilot pin: column type pilot pin surperficial fragile and damage after can't repair, because reparation can make the diameter on pilot pin column type surface reduce, and for the pilot pin on pyramid type surface, reuse after surface after damaging can being repaired, can improve the service life of pilot pin, particularly result of use is better when the thickness of sheet metal is big.

(5) specific embodiment
Embodiment:
A kind of progressive die feeding precision positioning device of taper seat pilot pin of elastic floating, form by backing plate 1, fixed head 3, taper seat pilot pin 5, stripper 8, piercing punch 2 and punching concave die 10, it is characterized in that: the correcting face 6 of taper seat pilot pin is pyramid type, the length of correcting face is 5mm, its coning angle is 0.5 °, and the head 7 of taper seat pilot pin is a dome-type; Taper seat pilot pin 5 is fixed on the fixed head 3, and spring 4 is equipped with at the top of taper seat pilot pin 5, and the other end of spring 4 and backing plate 1 join.After the taper correcting face 6 of taper seat pilot pin enters into the certain depth in correcting hole 11, its pyramid type correcting face 6 will closely contact with correcting hole 11, taper seat pilot pin 5 realizes that with correcting hole 11 no gap cooperates, thereby improved the feeding positioning accuracy, after taper seat pilot pin 5 and correcting hole 11 have realized that no gap cooperates, mould also can continue to press down, and at this moment taper seat pilot pin 5 keeps its position and makes the unlikely damage of mould by the compression of spring 4.This device is used in large-scale precision auto parts progressive die, and testing result shows that the metal blank positioning accuracy can improve 70%.
Claims (2)
