Abstract
The utility model discloses an edge trimming die with an ejecting mechanism. The edge trimming die with the ejecting mechanism comprises an upper die holder and a lower die holder, a punch and a lower die, wherein the upper die holder and the lower die holder are matched with each other, the punch and the lower die are fixed to the upper die holder and the lower die holder respectively, the punch is fixed to the lower side of the upper die holder through positioning pins and an upper die pressing plate, and the punch is matched with the lower die in shape and size. The edge trimming die with the ejecting mechanism is characterized by further comprising the ejecting mechanism arranged on a lateral side of the punch, the ejecting mechanism is embedded in the upper die holder and arranged together with the upper die holder in a sliding fit mode, the ejecting mechanism makes contact with the side face of the punch when sliding relative to the upper die holder in the vertical direction, and the ejecting mechanism comprises an ejector rod penetrating through the upper die holder and provided with an annular boss, and a spring which is arranged on the ejector rod in a sleeved mode and located between the annular box and the upper die pressing plate. The edge trimming die has the advantages that the ejecting mechanism can knock off burrs of forge pieces in time, burrs are effectively prevented from being hung on the punch, the punch is protected, accuracy of the forge piece size is ensured, and meanwhile overall labor intensity of operators is lowered and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of shaving die, is specifically related to a kind of shaving die with ejecting mechanism.
Background technology
At present, China forges the shaving die in field and is not all with ejecting mechanism, therefore, the shortcoming that existing shaving die exists is: the burr of forging are easy to hang to drift, operator needs with instrument, burr to be hit down in addition, thus, has both increased the labour intensity of operation, reduce again operating efficiency, easily caused again drift damage, forging ' s block dimension precision to reduce simultaneously.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of shaving die with ejecting mechanism that can either increase work efficiency and can protect drift.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of shaving die with ejecting mechanism, comprise: the upper bolster cooperatively interacting, die shoe, be individually fixed in drift, counterdie in aforementioned upper bolster, die shoe, aforementioned drift is fixed on upper bolster downside by alignment pin and upper molded plate, the shape of drift, size and counterdie match, it is characterized in that, also comprise: the ejecting mechanism that is arranged on aforementioned drift side, aforementioned ejecting mechanism embeds in upper bolster and joins installation with upper bolster cunning, ejecting mechanism in the process sliding up and down with respect to upper bolster with the contacts side surfaces of drift.
The aforesaid shaving die with ejecting mechanism, is characterized in that, aforementioned ejecting mechanism comprises: run through aforementioned upper bolster and have the push rod of annular boss, be enclosed within the spring on aforementioned push rod and between annular boss and upper molded plate.
The aforesaid shaving die with ejecting mechanism, is characterized in that, aforementioned ejecting mechanism is provided with two groups, is separately positioned on the both sides that drift is relative.
Usefulness of the present utility model is: ejecting mechanism can be hit the burr of forging down in time; effectively avoided burr to be suspended to drift; both protected drift; extended the service life of drift; guaranteed again the precision of forging ' s block dimension; meanwhile, reduce on the whole operator's labour intensity, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the cutaway view of a specific embodiment of the shaving die with ejecting mechanism of the present utility model;
Fig. 2 is the top view of the shaving die with ejecting mechanism in Fig. 1.
The implication of Reference numeral in figure: 1-upper bolster, 2-die shoe, 3-drift, 4-counterdie, 5-alignment pin, 6-upper molded plate, 7-annular boss, 8-push rod, 9-spring, 10-bolt.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
See figures.1.and.2, the shaving die with ejecting mechanism of the present utility model, comprise: upper bolster 1, die shoe 2, drift 3, counterdie 4 and ejecting mechanism, upper bolster 1 cooperatively interacts with die shoe 2, drift 3 is fixed on upper bolster 1 downside by alignment pin 5 and upper molded plate 6, counterdie 4 is fixed on die shoe 2 by bolt 10, the shape of drift 3, size and counterdie 4 match, ejecting mechanism is arranged on drift 3 sides, ejecting mechanism embeds in upper bolster 1 and with upper bolster 1 and slides and join installation, ejecting mechanism in the process sliding up and down with respect to upper bolster 1 with the contacts side surfaces of drift 3, thereby in time the burr of forging are hit down, effectively avoided burr to be suspended to drift 3, both protected drift 3, extended the service life of drift 3, guaranteed again the precision of forging ' s block dimension, simultaneously, reduced on the whole operator's labour intensity, improved operating efficiency.
As a kind of preferred scheme, ejecting mechanism comprises: run through the push rod 8 of upper bolster 1, and be enclosed within the spring 9 on push rod 8.Push rod 8 has annular boss 7, and annular boss 7 is positioned at the inside of upper bolster 1 all the time, and spring 9 is between annular boss 7 and upper molded plate 6.Push rod 8, when operation downwards, with the contacts side surfaces of drift 3, and moves downward, when spring 9 resets, resets thereupon in the elastic limit of spring 9, thereby smoothly, in time the burr of forging are hit down.
More preferably, ejecting mechanism is provided with two groups, is separately positioned on the both sides that drift 3 is relative, is symmetrical arranged, and hits the effective of burr down.
The shaving die with ejecting mechanism of the present utility model, its operation principle is as follows:
First forging stock is put into counterdie 4, again the upper bolster 1 with ejecting mechanism and drift 3 to pressing down, drift 3 is pressed in counterdie 4, now forging stock burr are croppedly fall and be attached on drift 3, when drift 3 returns to upwards operation, by forcing press (not shown), push rod 8 is applied to active force, push rod 8 is moved downwards, thereby burr are just by push rod 8 roof fall from drift 3.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
