Abstract
The present invention relates to a kind of secondary powder filler structures for powder pressing forming.Including inside casing（5）And outline border（6）, the inside casing（5）On be provided with material boots（2）, it is provided with driving device（1）Drive the inside casing（5）In outline border（6）Side-to-side movement within the scope of restriction.Under the action of feeding cam, material boots is enable to move left and right by cylinder when material boots are in charging position and be equipped with position detecting device, can accurately ensure to expect that boots are moved to designated position so as to complete to fill powder process twice；Rational in infrastructure, feeding is accurate, has extremely strong practicability.
Description
Technical field
The present invention relates to a kind of secondary powder filler structures for powder pressing forming, belong to powder metallurgical technology.
Background technology
During original linear feeding, double powder boots need front powder chamber to first pass through cavity, allow below powder chamber carry out first layer
Powder fills.Then powder retreats, and lifts on cavity, before powder chamber be parked in above cavity and carry out second and fill, if shortcoming is exactly
With step on cavity, when filling starts, there is gap between undershoot and cavity, the powder of front powder chamber caused to fall into gap,
Two layers of powder in double powder products is caused just to mix, influences product molding quality.
Invention content
The present invention can carry out a kind of needle of feeding well in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of rational in infrastructure
To the secondary powder filler structure of powder pressing forming.
The technical solution adopted by the present invention is thus：The present invention includes inside casing（5）And outline border（6）, the inside casing（5）On set
It is equipped with material boots（2）, it is provided with driving device（1）Drive the inside casing（5）In outline border（6）Side-to-side movement within the scope of restriction.
The inside casing（5）, outline border（6）Between be provided with to the inside casing（5）The guide holder that side-to-side movement is oriented to
（3）.
The outline border（6）Side is provided with detection inside casing（5）The position detecting device of movement position（4）.
The driving device（1）For cylinder.
It is an advantage of the invention that：Under the action of feeding cam, material boots are made by cylinder when expecting that boots are in charging position
It can move left and right and equipped with position detecting device, can accurately ensure to expect that boots are moved to designated position so as to complete to fill twice
Powder process；Rational in infrastructure, feeding is accurate, has extremely strong practicability.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
1 it is driving device in figure, 2 be material boots, 3 be guide holder, 4 be position detecting device, 5 be inside casing, 6 is outline border.
Specific embodiment
The present invention includes inside casing 5 and outline border 6, and material boots 2 are provided on the inside casing 5, be provided with driving device 1 drive it is described
The side-to-side movement within the scope of the restriction of outline border 6 of inside casing 5.
The guide holder 3 being oriented to 5 side-to-side movement of inside casing is provided between the inside casing 5, outline border 6.
6 side of outline border is provided with the position detecting device 4 of detection 5 movement position of inside casing.
The driving device 1 is cylinder.
The present invention the course of work be：When material boots 2 reach charging position, during this carry out matrix cavity in for the first time plus
Material, then gives cylinder 1 air inlet, and material boots is made to be moved to left end（It may insure that material boots can be moved steadily equipped with guide holder 3）, pass through
Position detecting device 4 ensures to expect that boots have been moved to left end, second of charging in matrix cavity is carried out during this, expects the two of boots
Secondary dress powder process terminates, and material boots allow material boots be in right end position waiting the as feeding cam is back in situ, then by cylinder 3
The dress powder process of two cycles so recycles.
