Structure includes the ejector of one group of ordered arrangement；The ejector includes cylinder body, piston and piston rod, and the piston is located at the cylinder
In vivo, the piston rod is located in the piston, and the cylinder body, piston and piston rod form a confined space, the confined air
It is interior to be contained with compressible gas.
In an embodiment of the utility model, the compressible gas is nitrogen.
In an embodiment of the utility model, the piston is equipped with sealing ring with the piston rod junction.
In an embodiment of the utility model, the sealing ring is rubber washer.
In an embodiment of the utility model, there are four the ejector settings, and four ejectors are in array
Arrangement.
In an embodiment of the utility model, the outside of the ejecting mechanism is equipped with mounting shell, the ejecting mechanism
It is mounted on by mounting shell on the workbench.
As described above, the punching machine stripper apparatus of the utility model, has the advantages that：Whole device is simple in structure,
Cost is relatively low, and due to being provided with one group of ejector below top plate, ejection ability is multiplied than individual layer die-cushion；Into parison
The part demoulding is smooth, the preforming time is short, blank temperature reduces less, be entirely capable of meeting product finish forging, improve work efficiency and
Product qualification rate.

Specific embodiment
Illustrate the embodiment of the utility model by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
It please refers to Fig.1 to Fig.3.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to
Coordinate the revealed content of specification, so that those skilled in the art understands and reads, be not limited to the utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjustment, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model
In the range of revealed technology contents can be covered.Meanwhile in this specification it is cited as " on ", " under ", "left", "right",
The term of " centre " and " one " etc. is merely convenient to understanding rather than to limit the enforceable scope of the utility model for narration,
Its relativeness is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of punching machine stripper apparatus, the punching machine includes punching machine body 1 and is located at
Workbench 2 immediately below the punching machine body 1 is placed with die-cushion (not shown) on workbench 2, and the stripper apparatus 3 is installed on
The workbench 2.
Referring to Fig. 2, the utility model is characterized in that, the punching machine stripper apparatus 3 specifically includes top plate 31 and is located at
31 lower section of top plate is used for the ejecting mechanism 32 that die-cushion is driven to move up and down, and the ejecting mechanism 32 includes one group of ordered arrangement
