Market.
In powder metallurgy production practices, product is by the relative motion extrusion forming between each die assembly, and on product
Blind hole often through die mandrel assembly forming.Since product blind hole is generally fit dimension, dimension precision requirement is stringenter,
Especially very high to the position degree required precision of blind hole, affected by many factors, production needs multiple demoulding to adjust when adjusting
Position degree.As shown in Figure 1, the blind hole at this requires position degree Φ 0.1mm, plug may slightly offset blind hole in forming process
Center, it is therefore desirable to gradually subtly adjust plug, this process needs not known according to the molding situation that produces every time
The position degree in direction adjusts, and usually eight hours time-consuming or more to adjust position degree, working efficiency is low.
Utility model content
The purpose of the utility model is to provide the mandrel component for quickly adjusting blind hole position degree in a kind of powder metallurgy forming,
Plug can be quickly adjusted, the offset of plug and blind hole center is reduced, guarantees that blind hole position degree, mode transfer are high-efficient.
The utility model provides the following technical solution:
The mandrel component of blind hole position degree, including plug and index dial, plug are quickly adjusted in a kind of powder metallurgy forming
Including the formed punch being successively vertically connected with and support link, index dial is fixed in support link；Support link is concentric with index dial
Setting, support link and formed punch eccentric setting.The formed punch and support link eccentric setting of plug deviate set point according to conical head
Direction rotate index dial, the cone on formed punch can be made around the center rotating of index dial, to compensate position degree deviation, thus
It realizes quickly adjustment position degree, improves mould and die accuracy and mode transfer efficiency.The fixed indexing plate in support link, it is convenient by dividing
Scale rotates plug, and plug is stable in a certain specific angle.
Preferably, formed punch includes formed punch ontology and conical head, and the hole bottom structure of conical head and blind hole matches, conical head position
In the top of formed punch ontology, conical head is arranged concentrically with formed punch ontology, and the top of conical head is equipped with cone.
Preferably, cone deviates the center of circle 0.005mm of support link.
Preferably, graduation mark is along the circumferential direction equipped on index dial.The angle of the recordable lower index dial rotation of graduation mark, just
In carrying out data acquisition and industrial analysis, the data reference of plug is adjusted as next time.
Preferably, the diameter of index dial is 6-8 times of the diameter of conical head, and index dial is exaggerated the angle of conical head rotation
Degree, facilitates observation and record.
The beneficial effects of the utility model are: by installing index dial, and the formed punch of plug and support in plug bottom
Connecting rod eccentric setting rotates index dial according to the direction that conical head deviates set point, the cone on formed punch can be made around index dial
Center rotating to realize quickly adjustment position degree, improve mould and die accuracy and mode transfer effect to compensate position degree deviation
Rate.Scale on index dial can amplify and record rotational angle when plug adjusts, and be convenient for data acquisition and technique point
Analysis.

Specific embodiment
As shown in Figures 2 to 4, the mandrel component of blind hole position degree, including core are quickly adjusted in a kind of powder metallurgy forming
Stick 1 and index dial 2, plug 1 include that the formed punch 11 being successively vertically connected with and support link 12, index dial 2 are fixed on support link
12 bottom；Support link 12 is arranged concentrically with index dial 2, support link 12 and 11 eccentric setting of formed punch.
As shown in figure 3, formed punch 11 includes formed punch ontology 111 and conical head 112, the hole bottom structure of conical head 112 and blind hole
Match, conical head 112 is located at the top of formed punch ontology 111, and conical head 112 is arranged concentrically with formed punch ontology 111, conical head
112 top is equipped with cone 113.
As shown in figure 3, cone 113 to support link 12 the center of circle distance D be 0.005mm, therefore tip position can
Tune range is Φ 0.01mm.
