The opening is then opened in the side of supporting table 152, the quantity of opening be it is at least one, preferably two, when it is two, chamber
The both sides of body all have opening, and in other words, the both sides of the cavity are in breakthrough status, meanwhile, which collectively forms with cavity falls
Hopper 154, so that the workpiece that punching is formed is gathered in charging conduit 154.
Second bending part 153 includes third surface and the 4th surface, and the first bending part 145 and the second bending part 153 are in water
Square to certain gap, third surface is the surface of the close upper mold 140 of supporting table 152, and first surface and third
Surface is parallel, and second surface and the 4th surface are mutual corresponding curved surface, the 4th surface be located at third surface and pedestal 100 it
Between；When workpiece is positioned in supporting table 152, when upper mold 140 is moved to lower die 150, and the first bending part 145 and second is bent
Portion 153 mutually staggers, to make workpiece be bent between the first bending part 145 and the second bending part 153.
When upper mold 140 is moved towards lower die 150, the first cutting member 141 and the second cutting member 151 have what is be bonded to each other to cut
State is cut, and press part 142 has close to supporting table 152 close to state, one end of punching part 143, which has, stretches into through-hole 155
Interior working condition.
When the first cutting member 141 and the second cutting member 151 are in shearing condition, the first shearing of the first cutting member 141
Second shear surface of face and the second cutting member 151 is bonded to each other, when workpiece is positioned in supporting table 152 and is located at the first cutting member
141 and second between cutting member 151 when, the wherein one side of workpiece at this time is contacted with the second cutting member 151, and upper mold 140 is by outer
When the actuating unit control in portion moves back and forth, the first cutting member 141 is moved towards the second cutting member 151, the first shear surface and second
I.e. cut-off workpiece is bonded to each other between shear surface.
When workpiece is positioned in supporting table 152, when upper mold 140 is moved towards lower die 150, to make workpiece be relatively fixed, work
Part should be at clamped condition, and in the present embodiment, the clamping of workpiece is completed jointly by press part 142 and supporting table 152, and uses pressure
Component 142 and supporting table 152 can be completed to clamp the short time of workpiece under specific require, when being convenient for saving processing in this way
Between, press part 142 and supporting table 152 have maximum distance and minimum range, when upper mold 140 is in initial position, press part
The distance between 142 and supporting table 152 are maximum, when upper mold 140 to lower die 150 move and reach capacity position when, press part 142
The distance between supporting table 152 is minimum, and the minimum range should be slightly bigger than the thickness of workpiece, i.e., press part 142 and workpiece it
Between rigid contact is not present, can by the position-limiting action of press part 142 and supporting table 152 in this way, when shearing, punching and bending
Workpiece to be fixed.
When upper mold 140 is moved towards lower die 150, and is located at extreme position, one end part of punching part 143 is located at logical at this time
In hole 155, the high-speed mobile of upper mold 140 so that the part workpiece short time between punching part 143 and through-hole 155 is by larger
Impact force, to according to punching part 143 concrete shape to workpiece punching.
Shown in Fig. 2 and Fig. 3, in the present embodiment, which further includes buffer gear 160, the buffer
Structure 160 includes the first positioning column 146, the second positioning column 161 and elastic component 163.
First positioning column 146 is fixedly installed in upper mold 140, and the second positioning column 161 is fixed at base body 110
On, the second positioning column 161 has positioning region 162, wherein the first positioning column 146, the second positioning column 161 and positioning region 162 can be with
Preferably cylindric for prism-shaped or cylindric, the axis of the first positioning column 146 is located at same with the axis of positioning region 162
On straight line, and elastic component 163 is set on positioning region 162, and elastic component 163 can be spring or rubber sleeve, when the first shearing
When part 141 and the second cutting member 151 are in shearing condition, elastic component 163 is in compressive state.It is for spring with elastic component 163
Example, in upper mold 140 into 150 moving process of lower die, the first positioning column 146 contacts with spring and first constantly by spring-compressed,
After upper mold 140 reaches capacity position, the reset force of spring reaches maximum, and the reset force of spring helps to slow down upper mold
140 impact force, while also contributing to the reset of upper mold 140.
Second positioning column 161 offers annular groove (not shown), positioning region close to the surface of the first positioning column 146
162 one end is fixedly installed in annular groove, the bottom connection of elastic component 163 and annular groove, when elastic component 163 is spring,
A part for spring is then located in annular groove.
As shown in fig.4, in addition, the surface setting fluted 180 of the close upper mold 140 of pedestal 100, and the second cutting member
151 and supporting table 152 be then arranged in groove 180 so that the groove 180 can be convenient for collect shearing after waste material.
To sum up, which, can by being bonded to each other between the first cutting member 141 and the second cutting member 151
To be sheared to workpiece, meanwhile, the supporting table 152 of composite punching die can be completed with the punching part 143 of upper mold 140 to work
The punching of part, the supporting table 152 further include the second bending part 153, and the first bending member 144 of upper mold 140 has the first bending
