Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, this hair of Detailed description of the invention is now compareed
Bright specific embodiment.Wherein, identical component uses identical label.
Fig. 1 is a kind of structural schematic diagram of forging with holes；Fig. 2 is a kind of use of a specific embodiment according to the present invention
In the principle schematic diagram of the composite die of forging edge-cutting and hole-punching.Referring to shown in Fig. 1-2, the present invention provides one kind for forging
The composite die of part edge-cutting and hole-punching is used to carry out the forging with holes 1 of forging molding the synchronization process of edge-cutting and hole-punching comprising
One pedestal 2, the pedestal 2 is provided with 3, pierce punches being rotatably connected 4 of the former seat being fixedly connected, described
Former seat 3 is removably connected with the former 31 cut off for the overlap 11 to 1 outer wall of forging with holes, the pedestal 2
Lower section is provided with elastic cushion 5, and the pedestal 2 is provided with multiple guide through hole, and the elastic cushion 5 is provided with and the guide through hole
The mandril 51 of slidable connection, the mandril 51 be connected with can the pierce punch 4 described in the outer lateral edge of pierce punch 4 axis direction
The support plate 52 for being used to support the forging with holes 1 of sliding, 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 scraper plate.
The working principle of composite die provided by the present invention for forging edge-cutting and hole-punching are as follows: in the forging 1 with holes
After forging molding, the forging 1 with holes of heat is placed in the support plate 52 (in Fig. 2 shown in dotted line), the yin is placed in
The type of mould 31 is intracavitary, so as to be that the forging 1 with holes provides positioning support by the support plate 52 and the former 31.
The trimming punch 6 moves downward under the drive of press machine (such as crank press), and the trimming punch 6 pushes the band
Hole forging 1 and the support plate 52 move downward, so as to be completed using the cutting edge of the former 31 to the forging 1 with holes
Trimming movement.
During the forging 1 with holes and the support plate 52 move downward, the pierce punch 4 and the forging with holes
After part 1 contacts, puncture motion can be completed using the cutting edge of the pierce punch 4.
The arrival of trimming punch 6 can after bottom dead center move upwards under the drive of press machine (such as crank press),
The scraper plate 32 can separate the overlap 11 of excision of the clamping stagnation on the trimming punch 6 at this time.
After the pierce punch 4 completes puncture motion, the elastic cushion 5 drives the forging with holes by the mandril 51
1 and the support plate 52 do homing action upwards, at this point, rotating the pierce punch 4, the outer wall of the pierce punch 4 is
Polishing removing can be carried out to the remaining burr of inner hole of the forging 1 with holes.When the forging 1 with holes and the support plate 52 to
