It answers, cooperate.
Although shaping position that above-mentioned powder metallurgy part sizing die frame plug adjustment device is able to achieve plug adjusts, but its
The occupied space for adjusting device is larger, causes powder trimmer integrally excessively high, during actual use and it is inconvenient for operation, need to be changed
Into.
Summary of the invention
The object of the present invention is to provide a kind of trimmer mould frame core rod shaping position adjustment mechanisms, with compact-sized, behaviour
Make convenient feature.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of trimmer mould frame core rod shaping position adjustment mechanism, including lower plate, set on the plug cylinder body of lower plate lower end
End cap and the plug for being slidably connected to plug cylinder end caps center, the plug cylinder end caps lower thread are connected with for supporting
The outer circle wall of the firmly plug block of plug lower end, the plug block is equipped with rotation lock follower, the lower plate
It is equipped with rotation lock driving mechanism, the rotation lock follower and rotation lock driving mechanism cooperate.
As an improvement of the present invention, the rotation lock follower is to be formed on plug block outer circle wall
Gear structure, the rotation lock driving mechanism are the worm screw rotationally supported on lower plate and with gear structure cooperation.
As an improvement of the present invention, cavity, the cavity position are formed between the plug cylinder end caps and lower plate
Inside lower plate, projection forms piston and is slidably connected in cavity on the plug
By using above scheme, plug cylinder end caps and lower plate are combined more compact, reduces whole occupancy
Complete machine height is shortened in space.
As an improvement of the present invention, the counterbore for resisting plug lower end is offered on the plug block.
By using above scheme, so that plug block more preferably resists plug, and it can prevent plug from moving radially, together
When but also complete machine structure is more compact, reduce occupied space.
In conclusion the invention has the following advantages:
Compared with the adjustment mechanism of plug shaping in the prior art position, trimmer mould frame core rod shaping position adjustment of the invention
The bottom of plug cylinder end caps is directly arranged in the plug block for controlling plug lower dead center by mechanism, and plug shaping position is adjustable, together
When greatly reduce the occupied space of plug shaping position adjustment mechanism；Plug cylinder end caps are embedded in lower plate, so that cavity position
Inside lower plate, but also overall structure is more compact, the space occupied, complete machine structure optimization are reduced.

Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
Embodiment one:
Referring to Fig. 1, a kind of trimmer mould frame core rod shaping position adjustment mechanism, including lower plate 1 and be mounted under lower plate 1
The plug cylinder end caps 2 at end further include plug 3, plug block 4 and worm screw 5.In conjunction with Fig. 2, through-hole is offered among lower plate 1
One 11 pass through for plug 3, and 1 lower end surface of lower plate offers the matching hole 12 that internal diameter is greater than one 11 internal diameter of through-hole.
Referring to Fig. 3, plug cylinder end caps 2 are cylindrical, and centre offers through-hole 2 21 and passes through for plug 3, plug cylinder
Projection forms a circle flange mounting disc 22 on the exogenesis wall of body end lid 2, is located at 22 top of flange mounting disc in plug cylinder end caps 2
Outer circle wall outer diameter and matching hole 12 internal diameter cooperate, the lower end surface that flange mounting disc 22 is butted on lower plate 1 passes through bolt
It being fixedly connected with lower plate 1, the upper surface of plug cylinder end caps 2 and matching hole 12 form cavity, and cavity is located inside lower plate,
Projection forms piston 31 and is slidably connected in cavity on plug 3, and the epicoele pipeline (figure being connected to cavity is connected on lower plate 1
In do not draw), be connected with the cavity of resorption pipeline (not drawing in figure) being connected to cavity in plug cylinder end caps 2.
The lower end surface of plug cylinder end caps 2 offers the internal thread hole 23 that internal diameter is greater than 2 21 internal diameter of through-hole, internal thread hole
Plug block 4 is threaded on 23, in conjunction with Fig. 4, plug block 4 is cylindrical, and 4 top outer circle wall of plug block is equipped with
The external screw thread 41 cooperated with internal thread hole 23, the upper surface of plug block 4 is for resisting 3 lower end of plug, the outer circle of plug block 4
Rotation lock follower is additionally provided on peripheral wall, rotation lock follower is to be formed on 4 lower outer circumferential wall of plug block
Gear structure 43, the outer diameter of gear structure 43 is greater than the outer diameter of external screw thread 41 and is exposed to outside plug cylinder end caps 2；Lower plate
1 lower end surface is equipped with the rotation lock driving mechanism cooperated with rotation lock follower, and rotation lock driving mechanism is rotation
The worm screw 5 for turning to be supported on lower plate 1 and cooperating with gear structure 43, worm screw 5 are mounted on the lower end of lower plate 1 by bracket 6
On face, the transmission mechanism of worm screw 5 and the composition of gear structure 43 has latching characteristics, which refers to that worm screw can be easily
Rotate gear, but gear can not rotary worm, when gear attempts rotary worm, the frictional force between gear and worm screw can allow snail
Bar keeps in situ.
Referring to figs. 5 and 6, core rod mould 7 is installed in trimmer, with undershoot mold 8, negative template 9 and upper punching on plug 3
When processing a product 10 as shown in Figure 5, which is stepped for (not drawing in figure) cooperation.It is produced when needing to adjust
The ladder depth of product inner hole is used to when producing another money product, the core rod mould 7 on no replacement is required plug 3, it is only necessary to plug 3
Lower dead center be adjusted, by the gear structure 43 on rotary worm 5 and plug block 4 can make plug block 4 relative to
Plug cylinder end caps 2 rotate, and plug block 4 is slided by the way that the internal thread hole 23 on external screw thread 41 and plug cylinder end caps 2 is opposite,
So that the position height of plug block 4 changes, and then has adjusted the lower dead center of plug 3, i.e., to 3 shaping position of plug into
Adjustment is gone, when the position height of plug 3 is adjusted to suitable position, worm screw 5 stops operating under the action of self-lock force
The shaping position of plug 3 is locked, consequently facilitating shaping has the compacted products of different height plug step.
