Abstract
The utility model discloses a kind of powder metallurgy former of the pre- anti-sticking powder of energy, including former seat, die cavity is provided with the former seat, low punch is installed below the die cavity, plug hole is provided with the low punch, is slided in plug hole and is provided with plug, the plug bottom is fixed on plug gland, the plug includes core head and mandrel body, and some arc grooves are annularly provided with the mandrel body, is additionally provided between the core head and mandrel body and scrapes powder ring.
Description
Technical field
The utility model is more particularly to a kind of powder metallurgy die component of the pre- anti-sticking powder of energy.
Background technology
Many powder metallurgy producers are in suppression process at present, all there is between mould that mutually the phenomenon of clamping stagnation, the lighter need again
Mould is dismounted, takes time and effort, severe one mold damage, not only aggravates die cost, and is taken time and effort, has a strong impact on normal life
Production.The reason for catching phenomenon is mainly that powder is dropped into the plug hole of low punch, when plug shrinks, by powder card
Firmly.
Utility model content
The purpose of this utility model is to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of powder smelting of the pre- anti-sticking powder of energy
Golden former, the powder metallurgy former can effectively prevent the card powder phenomenon that plug occurs during low punch moves.
What the technical solution of the utility model was realized in：A kind of powder metallurgy former of the pre- anti-sticking powder of energy, including the moon
Die holder, die cavity is provided with the former seat, low punch is installed below the die cavity, plug is provided with the low punch
Hole, slide in plug hole and be provided with plug, the plug bottom is connected with mandrel stem, and is fixed on plug gland by mandrel stem
On, the plug includes core head and mandrel body, and some arc grooves, the core head are annularly provided with the mandrel body
It is additionally provided between mandrel body and scrapes powder ring.
Further, the arc groove is five, and is uniformly arranged on mandrel body.
Compared with prior art, the beneficial effects of the utility model are：By reducing the cooperation between plug and low punch
Area, the frictional force between mould is reduced, while powder ring is scraped in increase on plug, when it is moved in plug hole, by scraping powder
The continuous scraping of ring, the powder particle between plug hole is eliminated in time, so as to reach the effect for eliminating mould clamping stagnation.
Brief description of the drawings
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not form to this reality
With new any restrictions.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of plug of the present utility model；
Fig. 3 is the enlarged drawing of part A in the utility model Fig. 2.
In figure：1st, former seat；2nd, die cavity；3rd, low punch；4th, plug gland；5th, core head；6th, mandrel body；7th, arc is recessed
Groove；8th, powder ring is scraped；9th, mandrel stem.
Embodiment
Refering to a kind of powder metallurgy former of pre- anti-sticking powder of energy shown in Fig. 1 to Fig. 2, including former seat 1, the former seat
Die cavity 2 is provided with 1, the lower section of die cavity 2 is provided with low punch 3, and (bottom of low punch 3 is fixed on pressure by the gland of low punch 3
Other positions of machine processed), plug hole is provided with the low punch 3, is slided in plug hole and is provided with plug, the plug bottom connects
Mandrel stem 9 is connected to, and is fixed on by mandrel stem 9 on plug gland 4, the plug includes core head 5 and mandrel body 6, described
Some arc grooves 7 are annularly provided with mandrel body 6, is additionally provided between the core head 5 and mandrel body 6 and scrapes powder ring 8.
Process is as follows when in use for the utility model, and powder is dropped among the die cavity 2 of former, upper punch start into
Row punch forming, after punching press completion, former seat 1 is begun to decline, and the product of shaping is ejected by low punch 3, meanwhile, plug is opened
Begin to decline, finally release the product of shaping.Due to being provided with some arc grooves 7 on the mandrel body 6 of plug, so plug
Cooperation area between body 6 and the plug hole of low punch 3 is substantially reduced, and frictional force therebetween is greatly reduced, while
Powder ring 8 is scraped in increase on plug, is made plug in moving downward, by scraping the continuous scraping plug hole inwall of powder ring 8, is eliminated core in time
Powder particle between rod hole, so as to reach the effect for eliminating mould clamping stagnation.
Further, the arc groove 7 is five, and is uniformly arranged on mandrel body 6.Specifically, the utility model
Plug on arc groove 7 be arranged to five, the quantity is effectively reduced the contact area between plug and former so that
The powder of clamping stagnation is less, while can more efficiently be scraped powder ring 8 and struck off.
Embodiment provided above is better embodiment of the present utility model, is only used for convenient explanation the utility model, and
It is non-to make any formal limitation, any those of ordinary skill in the art to the utility model, if not departing from
In the range of the utility model carries technical characteristic, locally change or repair using made by the utility model disclosed technology content
The equivalent embodiment of decorations, and without departing from the technical characteristics of the utility model content, still fall within the utility model technical characteristic
In the range of.
