In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now control illustrates this
Bright specific embodiment.Wherein, identical part adopts identical label.
Fig. 1 is a kind of structural representation of forging with holes；Fig. 2 is that one kind of a specific embodiment according to the present invention is used
In the principle schematic diagram. of the composite die of forging edge-cutting and hole-punching.Referring to shown in Fig. 1-2, the invention provides a kind of be used for forging
The composite die of part edge-cutting and hole-punching, which is used for carrying out the forging with holes 1 of forging molding the synchronization process of edge-cutting and hole-punching, and which includes
One base 2, the base 2 are provided with 3, pierce punch being rotatably connected 4 of a former seat being fixedly connected, described
Former seat 3 is removably connected with the former 31 for being cut off to the overlap 11 of 1 outer wall of forging with holes, the base 2
Lower section is provided with cushion 5, and the base 2 is provided with multiple guide through hole, and the cushion 5 is provided with and the guide through hole
The push rod 51 of slidable connection, the push rod 51 be connected with can on the outside of the pierce punch 4 along the pierce punch 4 axis direction
The gripper shoe 52 for supporting the forging with holes 1 slided, the former 31 are removably connected with scraper plate 32, the former 31
Top is provided with the trimming punch 6 with 32 slidable connection of the scraper plate.
The operation principle of the composite die for forging edge-cutting and hole-punching provided by the present invention is：In the forging with holes 1
After forging molding, the forging described with holes 1 (in Fig. 2 shown in dotted line) of heat is placed in the gripper shoe 52, described the moon is placed in
In the die cavity of mould 31, support such that it is able to provide positioning by the gripper shoe 52 and the former 31 for the forging with holes 1.
The trimming punch 6 is moved downward under the drive of forcing press (such as crank press), and the trimming punch 6 promotes the band
Hole forging 1 and the gripper shoe 52 are moved downward, so as to complete to the forging with holes 1 using the cutting edge of the former 31
Trimming action.
During the forging with holes 1 and the gripper shoe 52 are moved downward, the pierce punch 4 and the forging with holes
After part 1 is contacted, puncture motion can be completed using the cutting edge of the pierce punch 4.
The trimming punch 6 is arrived at and after bottom dead center can be moved under the drive of forcing press (such as crank press) upwards,
The overlap 11 not cut off that now scraper plate 32 can be by clamping stagnation on the trimming punch 6 is separated.
After the pierce punch 4 completes puncture motion, the cushion 5 drives the forging with holes by the push rod 51
1 and the gripper shoe 52 do homing action upwards, now, rotate the pierce punch 4, the outer wall of the pierce punch 4 is
Polishing removing can be carried out to the burr that the endoporus of the forging with holes 1 is remained.When the forging with holes 1 and the gripper shoe 52 to
On when moving to initial position, you can make the pierce punch 4 stop operating.So as to complete trimming, a punch operation.
The cushion 5 can be hydraulic mechanism (such as hydraulic jack) or the air pressure mechanism for being connected with supporting plate.So
The stroke of the gripper shoe 52 can be controlled well and enough support forces are provided.
