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 On when moving to initial position, the pierce punch 4 can be made to stop operating.To complete trimming, a punch operation.

The elastic cushion 5 can be the hydraulic mechanism (such as hydraulic jack) or air pressure mechanism for being connected with supporting plate.In this way The stroke of the support plate 52 can be controlled well and enough support forces are provided.

The pierce punch 4 can be connect by belt with motor (not shown), comparable in this way to be easy to control institute State the parameters such as spinning movement and the revolving speed of pierce punch 4.Certainly, in order to enable the pierce punch 4 easily with Aperture can be arranged to retain enough installation spaces in side wall in the connection of the equipment such as external motor, the former seat 3.

In a preferred embodiment, the former seat 3 can not be annular, but concave structure, that is to say, that described One side wall of former seat 3 is open architecture, can ensure enough installation spaces for the pierce punch 4 and outside in this way The connection of equipment, and laid convenient for carrying out installation to the former 31.

For the ease of processing to the different forging 1 with holes, the pedestal 2 settable mounting bases 21 connect The pierce punch 4 is connect, in this way, rotational structure may be provided in the mounting base 21, when needing replacing the pierce punch 4 Or when maintenance rotational structure, the mounting base 21 need to only be removed so that package unit modularization, it is convenient for safeguarding more It changes.

In a preferred embodiment, the kind of drive for rotating the pierce punch 4 is also possible to pass through transmission gear The mode of system provides power.

Fig. 3 is the broken section structural schematic diagram of the pierce punch of Fig. 2, shown in Figure 3, in a preferred embodiment In, in order to further ensure the pierce punch 4 to the grinding effect of burr, annular groove 41 has been can be set in the pierce punch 4, It is provided with elastic webbing 42 in the annular groove 41, is provided with sanding belt 43 on the elastic webbing 42.The elastic webbing 42 can be rubber Adhesive tape or other elastic materials, the sanding belt 43 can be the ring being made of muti-piece grinding wheel being bonded on the elastic webbing 42 Shape grinding wheel is also possible to the sand paper being bonded on the elastic webbing 42.In punch process, the sanding belt 43 is squeezed into institute Annular groove 41 is stated, when the pierce punch 4 rotation polishes to the inner-hole burr of the forging 1 with holes, the sanding belt 43 It can be close to the inner hole of the forging with holes 1, under the action of elastic webbing 42 so as to ensure the grinding effect to burr.

In a further advantageous embodiment, the mode that turning also can be used in the pierce punch 4 eliminates burr, That is the consistent cutter groove of axis direction of the side wall of the pierce punch 4 settable at least one and the pierce punch 4, It may be provided with the lathe tool or scraper connected by spring in the cutter groove, in this way, in punch process, the lathe tool or scraper quilt It is squeezed into the cutter groove, when the pierce punch 4 rotation polishes to the inner-hole burr of the forging 1 with holes, the vehicle Knife or scraper can be close to the inner hole of the forging with holes 1 under the action of the spring, to generate turning effect to burr, ensure polishing Effect.

Composite die provided by the present invention for forging edge-cutting and hole-punching, by forging trimming with holes, punching operation by dividing It drives row into be changed to carry out simultaneously, eliminate centre melts down heating process, and mold only needs once mounting that edge-cutting and hole-punching can be completed Two procedures reduce tooling manufacturing cost, avoid and install repeatedly, improve production efficiency, saved production cost, it is ensured that Forging quality.In addition, being handled in punch process, while to inner-hole burr, so as to save subsequent turning process It carries out, working time is greatly saved, reduces labor intensity.

It will be appreciated by those skilled in the art that although the present invention is described in the way of multiple embodiments, It is that not each embodiment only contains an independent technical solution.So narration is used for the purpose of for the sake of understanding in specification, The skilled in the art should refer to the specification as a whole is understood, and by technical solution involved in each embodiment Regard as and can be combined with each other into the modes of different embodiments to understand protection scope of the present invention.

The foregoing is merely the schematical specific embodiment of the present invention, the range being not intended to limit the invention.It is any Those skilled in the art, made equivalent variations, modification and combination under the premise of not departing from design and the principle of the present invention, It should belong to the scope of protection of the invention.
