When automatic punching device 12 is punched out, the engaging structure and following connection structures are in meshing state, so that described
Connecting rod swing arm mechanism 2-1 drives the moving tooth position-limit mechanism 2-2 rotations.
In order to enable the swing of the lower link 2-1-2 is more flexible, the other end of the upper connecting rod 2-1-1 passes through described
Middle shaft 2-1-4 is connected to one end of the lower link 2-1-2, specific to be realized using such as lower structure：The upper connecting rod 2-1-1 with
One end of the middle shaft 2-1-4 connections is provided with sliding slot, and the middle shaft 2-1-4 is slided in the sliding slot, and with described
Upper connecting rod 2-1-1 is reciprocating, the lower link 2-1-2 to be driven to swing.
The moving tooth position-limit mechanism 2-2 for connecting and driving as the connecting rod swing arm mechanism 2-1, as shown in figure 4, described
Moving tooth position-limit mechanism 2-2 further includes driving lever 2-2-2 and shift plate 2-2-3；The shift plate 2- is fixed in one end of the driving lever 2-2-2
In 2-3, the other end is set to outside the shift plate 2-2-3, and is set and coordinated with the engaging structure of described swing arm 2-1-6 one end
Connection structure；Described group of tongue 2-2-1 is fixed in the shift plate 2-2-3, and compression bullet is additionally provided in described group of tongue 2-2-1
Spring can be such that the tongue 2-2-1 that dials is slided to the direction engaged with the gear 3-2；The shift plate 2-2-3 is sheathed on the rotation
On rotary shaft 3-1 in mechanism 3, and pass through the tongue 2-2-1 that dials and drive the rotary shaft 3-1 with engaging for the gear 3-2
Rotation.In the present embodiment, the connection structure is ball head structure；The U-shaped groove of the ball head structure and the swing arm 2-1-6
Or square groove matches, the ball head structure can the relative motion in the U-shaped groove or square groove, with described in drive
Moving tooth position-limit mechanism 2-2 is rotated, and the position of engagement is at A；In this embodiment, driving lever of the connection structure for ball head structure is known as
Bulb driving lever.
It should be noted that as the structure directly being connect with the workpiece 11, as shown in Fig. 2, the rotating mechanism 3
Gear 3-2 is set to the middle part of the rotary shaft 3-1, and positioned at the top of the lower die float plate 1-2-4；It is in order to enable described
Gear 3-2 is more firm, and the gear 3-2 is fixed on by the second positioning key 9 on the rotary shaft 3-1；Second positioning
Key 9 can be one or multiple.In the top of the gear 3-2, it is provided with the institute of the moving tooth position-limit mechanism 2-2
Shift plate 2-2-3 is stated, the top of the shift plate 2-2-3 is the upper end of the rotary shaft 3-1, is provided with the retainer positioning plate 3-
3, likewise, in order to enable the retainer positioning plate 3-3 is consolidated, it is arranged on the rotary shaft 3-1, the retainer positioning plate 3-
3 are fixed on the upper end of the rotary shaft 3-1 by the first positioning key 8, first positioning key 8 can be one or
It is multiple.At least two are additionally provided on the retainer positioning plate 3-3 for fixing the positioning pin 10 of workpiece to be processed 11, to realize
Positioning to the workpiece 11 makes it be stably fixed on the retainer positioning plate 3-3.
Again it should be noted that automatic punching device 12 described in the embodiment of the present application be that by punching it is automatic into
Row, i.e., without manually the workpiece 11 is carried and be positioned, so, the embodiment of the present application is there is provided above-mentioned each mechanisms
Afterwards, it is also provided with direction and location mechanism 4.The setting of the mechanism not only realizes the gear 3-2 and determines angle one-directional rotation, also real
The automatic positioning of the workpiece 11 is showed.
Specifically, the direction and location mechanism 4 includes more than one location hole 4-1 and groove pin 4-2, the location hole
4-1 is set to the lower face of the gear 3-2, is spaced at a predetermined angle between each location hole 4-1；The groove pin 4-2 with
The location hole 4-1 matches, and is arranged on the position that is relatively fixed with the location hole 4-1 on the gear 3-2, and be located at
The upper surface of the lower die float plate 1-2-4, and can be slided up and down under the action of the spring in the groove pin 4-2；Institute
It states groove pin 4-2 to limit the gear 3-2, and the gear 3-2 is made to determine angle one-directional rotation.
Wherein, the groove pin 4-2 limits the gear 3-2, and the gear 3-2 is made to determine angle one-directional rotation, tool
Body includes：When the upper mold 1-1 moves to the bottom dead center position from the top dead center position, the groove pin 4-2 is slipped into
The location hole 4-1 makes the gear 3-2 not rotate, while described group of tongue 2-2-1 is drawn from the current tooth socket of the gear 3-2
Enter in adjacent tooth socket；It should be noted that the groove pin 4-2 slips into the location hole 4-1, the gear 3-2 is made not turn
It is dynamic, it is because being internally provided with the spring based on the groove pin 4-2, and the spring in state is drawn high, that is, is given at this time
The groove pin 4-2 holding powers so that the groove pin 4-2 is stuck in the location hole 4-1, so that the gear 3-2 is not
Rotation.
When the upper mold 1-1 is from the bottom dead center position to the top dead center position, the gear 3-2 is described
Dial and rotate under the action of tongue 2-2-1, the lower face of the gear 3-2 successively with the low side of the groove pin 4-2 to high end in contact
(bevel shape, so as to there is low side and high-end), is internally provided with the spring, as the gear 3-2 based on the groove pin 4-2
During rotation, the lower face of the gear 3-2 can contact the groove pin 4-2, and the groove pin 4-2 can be by the gear 3-2
Lower end surface pressure effect, by the spring-compressed inside the groove pin 4-2, so as to which the groove pin 4-2 determines from current
Position hole 4-1 is skidded off and is slipped into adjacent location hole 4-1 so that the gear 3-2 determines angle one-directional rotation.It liquidates to realize
Hole is accurately positioned, in the embodiment of the present application, the number of teeth of the quantity of the location hole 4-1 and the gear 3-2 and described
The punching hole count of workpiece 11 is identical.

It does not rotate, then the workpiece 11 does not rotate, and the stripper 1-1-4 compresses the workpiece 11, and in the punch-pin 1-1-2
Under the action of first hole is gone out.Then, the upper mold 1-1 is returned from the bottom dead center position to the top dead center position,
The stripper 1-1-4 exits the waste material that the workpiece 11 is swept away；During return, the upper mold 1-1 continues to drive
The upper connecting rod 2-1-1 is run up, and the middle shaft 2-1-4 slides into lower end from the upper end of the sliding slot, so that under described
Connecting rod 2-1-2 the middle shaft 2-1-4 drive the corresponding angle of lower swing (with angle direction during upper mold 1-1 downlinks on the contrary,
Angle number is identical), and by the lower rotary shaft 2-1-5 drive the swing arm 2-1-6 rotate corresponding angle (under upper mold 1-1
Angle direction during row is on the contrary, angle number is identical)；Further, the U-shaped groove is engaged with the ball head connecting rod, is made described
Moving tooth position-limit mechanism 2-2 rotates (opposite with rotation direction during upper mold 1-1 downlinks) around the rotary shaft 3-1, at this point, the tooth
Wheel 3-2 rotates corresponding angle under the stirring of described group of tongue 2-2-1, the groove pin 4-2 of the direction and location mechanism 4 and described
Location hole 4-1 coordinates, and the groove pin 4-2 can be acted on by the lower end surface pressure of the gear 3-2, by the groove pin 4-
Spring-compressed inside 2, so as to which the groove pin 4-2 is skidded off from current location hole 4-1 and slipped into adjacent location hole 4-1
In so that the gear 3-2 determines angle one-directional rotation；Further, the gear 3-2 drives the rotary shaft 3-1 rotations, together
When cause the retainer positioning plate 3-3 of the rotary shaft 3-1 upper ends that the workpiece 11 is driven to synchronize and determines angular turn；Realize
The automatic precise positioning of the workpiece 11.
