Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model can be by right
Require that the multitude of different ways limiting and covering is implemented.
With reference to Fig. 1, preferred embodiment of the present utility model provides a kind of multipart punch, including for punching, cut equipment
Be connected punch-holder shank 10, be connected with punch-holder shank 10 for the punch edge 20 that object rushes, cuts processing, on punch-holder shank 10
It is machined with through installation passage 100, fixing in passage 100 is installed is equiped with for connecting punch-holder shank 10 and punch edge 20
Connector 30, one end of connector 30 extends to install outside passage 100, and punch edge 20 is removably attachable to connector 30
Extend to install in the part outside passage 100.Multipart punch of the present utility model includes punch-holder shank 10 and punch edge 20, drift
Handle 10 is with for being connected, the connector 30 of punch-holder shank 10 and punch edge 20 is fixing to be connected, and punch edge 20 is removable with connector 30
Unloading connection, being connected by interior hexagonal cylindrical head stay bolt so comparing existing punch-holder shank and punch edge, this novel combination
In drift, being connected owing to punch-holder shank 10 is fixing with connector 30, and punch edge 20 removably connects with connector 30, it connects
After punch-holder shank 10 and punch edge 20 be difficult to occur to connect insecure, so safety is high when using, there is potential safety hazard
Probability is low；It is connected because punch-holder shank 10 is fixing with connector 30 again, and punch edge 20 and connector 30 removably connect, so
Dismountable drift can be not required in blanking process and can carry out the fastening of punch edge 20, additionally, when carrying out another kind of forging
Time die-cut, only need to change punch edge 20, therefore, multipart punch of the present utility model compares existing multipart punch, its
Deposit advantage convenient, time saving and energy saving, easy to spread in use.
Alternatively, as depicted in figs. 1 and 2, connector 30 is in shaft-like, including stop section 31 and the company that is connected with stop section 31
The section of connecing 32；Passage 100 is installed include for installing stop section 31 and the first paragraph 101 preventing stop section 31 from rotating and first paragraph
101 are connected for the second segments 102 installing linkage section 32, and in linkage section 32 is installed in second segment 102 and one end extends to the
Outside two-stage nitration 102, punch edge 20 is removably attachable on the segment section extended to outside second segment 102 of linkage section 32；Drift

Thread segment 322 even；The top of light bar segment 321 is connected with the bottom of stop section 31, second segment 102 in light bar segment 321 phase
The shape joined, is not only convenient for installing light bar segment 321, and prevents the light bar segment 321 being installed in second segment 102 from occurring rocking, from
And affect the rushing of punch edge 20, cut action；Being machined with external screw thread on the periphery wall of thread segment 322, its end extends to second
Outside section 102, punch edge 20 being machined with the internal thread hole 201 mated with thread segment 322, punch edge 20 passes through internal thread hole
201 removably connected with connector 30 with coordinating of thread segment 322.Punch edge 20 is by internal thread hole 201 and thread segment 322
Cooperation removably connect with connector 30, it is simple to the attended operation of punch edge 20 and connector 30.
In the present embodiment, as in figure 2 it is shown, be machined with the first installing hole 104 for installing retainer 40 on punch-holder shank 10；
Retainer 40 is detachably mounted in the first installing hole 104, and the top of retainer 40 and stop section 31 is supported.
In the present embodiment, as in figure 2 it is shown, punch-holder shank 10 is cylindrical, first paragraph 101 and second segment 102 are along punch-holder shank 10
Axis direction is sequentially arranged, and the first installing hole 104 is that the axis of through hole and vertical punch-holder shank 10 is arranged；Punch edge 20 is in post
Shape, its top is machined with the internal thread hole 201 of indent.Preferably, retainer 40 is latch, and latch is installed in the first installation
In hole 104, and support with the top of stop section 31.
Preferably, as shown in Figures 2 and 3, for more preferable aligning punch handle 10 and punch edge 20, this preferred embodiment
In, the bottom of punch-holder shank 10 is provided with evagination and cylindrical positioning boss 105；The top of punch edge 20 is provided with indent and with fixed
Position boss 105 coupling detent 202, internal thread hole 201 from the bottom land of detent 202 along the axis side of punch edge 20
To extension.By arranging positioning boss 105 and detent 202, by positioning boss 105 and the coupling of detent 202, can
More easily aligning punch insert 20 and punch-holder shank 10.
Preferably, as it is shown on figure 3, owing to punch edge 20 is threaded connection with connector 30, for convenience of and labour-saving
Punch edge 20 is combined on connector 30, in this preferred embodiment, the periphery wall of punch edge 20 arranges multiple use
In the second installing hole 203 installing the force-applying piece making punch edge 20 rotate when screwing under external force with connector 30.Rotation
When closing punch edge 20 and connector 30, only need to first force-applying piece be installed in the second installing hole 203, the most again to force-applying piece
Apply the active force rotated, can easily punch edge 20 be combined on connector 30.
In this specific embodiment, multiple second installing holes 203 are arranged along the circumferential uniform intervals of punch edge 20, and each the
The axis of the two vertical punch edges 20 of installing hole 203.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
