Abstract
The utility model discloses an extrusion die which comprises a die frame and a concave die and a convex die which are mounted on the die frame. The extrusion die is characterized in that the notch size of the concave die is identical to the punch size of the convex die, and the upper section of a notch is provided with a tapered opening. The extrusion die disclosed by the utility model works together with a common blanking die to produce blanked products with high size precision and good cut finish without use of a fine blanking equipment or fine blanking die.
Description
Technical field: the utility model relates to a kind of diel, is specifically related to a kind of extrusion die.
Background technology: at present high for dimensional accuracy, otch fineness is good dashes part, will produce towards equipment and fine blanking die with essence usually, but essence is expensive towards equipment price, the fine blanking die manufacture difficulty is big, generally is difficult to bear than small enterprise.
Summary of the invention: in view of disadvantages of background technology, the purpose of the utility model aims to provide a kind of and common punch die and is used in combination, the extrusion die that dashes the part product that just ability production dimensional accuracy is high on common punch press, otch fineness is good.
The utility model takes following technical scheme to accomplish:
A kind of extrusion die comprises mould bases and the concavo-convex mould of on mould bases, installing, and it is characterized in that: the drift of the blurt out size and the punch of die is measure-alike, and the epimere of blurting out has the awl mouth.The difference in size of awl mouthful concentric reducer is at 0.6-1.0mm.
The extrusion die of said structure is used in combination with common punch die, at first on common punch press, goes out in advance towards part with common punch die, leaves the size surplus of 0.5 millimeter in advance towards part; Otch fineness is relatively poor; Then will be in advance be put into towards part and carry out punching press with common punch press in the extrusion die, its course of work is such: punch heads in advance towards part through the blurting out of die, and is extruded calendering towards part at the epimere of blurting out (awl mouth) in advance in the meantime; Accomplish sized at the hypomere of blurting out; So finally come out to dash part product size precision high, otch fineness is good, with through essence towards equipment and fine blanking die production to dash the part product the same.
Description of drawings:
Fig. 1 is the structure chart of the utility model.
The specific embodiment: as shown in the figure, this extrusion die, the die 2 and the punch 3 that comprise mould bases 1, on mould bases 1, install; The drift of blurt out 5 sizes and the punch 3 of die is measure-alike; Also with identical towards the appearance and size of part product, the epimere of blurting out of die 2 has awl mouth 4, and the tapering of awl mouth 4 is 8 °; The height of awl mouth 4 is 3mm, and the difference in size of awl mouthful concentric reducer is at 0.85mm like this.
Above-mentioned extrusion die is used in combination with common punch die; At first on common punch press, go out in advance towards part, will be put into towards part in advance then and carry out punching press in the extrusion die with common punch die, punch head on blurt out through die towards part in advance during; Be extruded calendering towards part at the epimere of blurting out (awl mouth) in advance; Accomplish sized at the hypomere of blurting out, thus finally come out to dash part product size precision high, otch fineness is good.
