Abstract

The utility model discloses a kind of unidirectional punching assembling dies, it adopts a split structure, including hole punched device and shear, the hole punched device includes punching bucket, it rushes block and is located at the first jumper bar rushed on block, the conical cavity for placing blank is formed in the punching bucket, internal diameter gradually becomes smaller the cavity from top to bottom, the bottom of cavity is equipped with gasket, gap is equipped between the gasket and the inner wall of cavity, the shear includes the trimming half module to match with punching bucket and the drain cap piece positioned at trimming half module lumen centers, the inner hole for accommodating and rushing block is equipped in the middle part of the drain cap piece, the diameter of the inner hole is greater than the diameter for rushing block.The utility model reduces the risk that forging punching forms scrap of the product since unidirectional punching, 100% avoids punching step, gross weight;The use for reducing punching trimming, has saved cost.

Description

A kind of unidirectional punching assembling die
Technical field
The utility model relates to forge punching techniques field, especially a kind of unidirectional punching assembling die.
Background technique
Forging industry tradition punch pattern is that formed punch is pressed into blank by blank upper surface using formed punch at present, is then overturn Blank, then formed punch or trimming are pressed by lower end surface, it presses again, generates shear effect by trimming or formed punch and blank and then reach To the purpose of forging punching.Traditional punch pattern needs to be pressed into formed punch or trimming in blank both ends of the surface in two times, it is difficult to guarantee punching The concentricity of head and trimming, internal diameter forms punching step or punching recess when in turn resulting in punching, relatively due to punch size It is small, blank temperature is higher, punching recess is difficult to be found to remove, so formed forging defect cause scrapping for product;Tradition punching The hole mode activity duration is longer, and self-strength declines under the action of formed punch is pressed into after blank high temperature again, is under pressure after effect, rushes Easily-deformable, abrasion, causes the service life of formed punch shorter;Trimming is generally sticked together with core material, it is difficult to it utilizes again, at This is higher;Traditional punch pattern blank needs to overturn, and places formed punch and trimming is both needed to adjustment position, the activity duration is long, low efficiency.
Utility model content
Purpose of the utility model is to solve the above problems, provide a kind of unidirectional punching assembling die.
The technical solution that the utility model solves the above problems is as follows: a kind of unidirectional punching assembling die, use are split type Structure, including hole punched device and shear, the hole punched device include punching bucket, rush block and be located at the first punching rushed on block Bar, the punching bucket is interior to form the conical cavity for placing blank, and internal diameter gradually becomes smaller the cavity from top to bottom, and the bottom of cavity is set There is gasket, gap is equipped between the gasket and the inner wall of cavity, the shear includes the trimming to match with punching bucket Half module and drain cap piece positioned at trimming half module lumen centers are equipped with the inner hole for accommodating and rushing block in the middle part of the drain cap piece, the inner hole Diameter is greater than the diameter for rushing block.
Further, the second jumper bar is added on first jumper bar, second jumper bar pushes the first jumper bar, the first jumper bar Push so that blank front end rush core and drain cap piece realization rush core shear so that separated with blank, completion punching.
Further, the internal diameter of the trimming half module is 5-7mm bigger than the diameter of punching bucket.
Further, the inner cavity top edge arc transition of the trimming half module, it is convenient to blank guide-localization.
Further, the gap between the gasket and the cavity of punching bucket is 4-6mm, and gasket is avoided to become because of high-temperature operation Friction even stuck phenomenon occurs when ejecting blank with punching bucket for shape.
Further, the gap of the inner hole for rushing block and drain cap piece is 4-6mm, when avoiding rushing block shearing core material and is leaked Disc generates interference.
The utility model has the following beneficial effects:
1, the utility model solves blank punching centring problems using adaptation punching bucket and trimming half module;
2, the utility model rushes block and drain cap piece using adaptation, solves blank punching and needs turning problem;
3, the utility model avoids punching step, gross weight due to unidirectional punching, 100%, reduces forging punching and is formed The risk of scrap of the product;The use for reducing punching trimming, has saved cost.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is operation schematic diagram when the utility model is used.
In figure: 1, punching bucket, 2, blank, 3, gasket, 4, rush block, the 5, first jumper bar, 6, trimming half module, 7, drain cap piece, 8, Second jumper bar, 9, rush core.
Specific embodiment
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached Figure, is described in further detail the utility model.
A kind of unidirectional punching assembling die as illustrated in fig. 1 and 2, adopts a split structure, including hole punched device and shearing Device, the hole punched device include punching bucket 1, rush block 4 and be located at the first jumper bar 5 and the second jumper bar 8 rushed on block 4, punching The conical cavity for placing blank 2 is formed in bucket 1, internal diameter gradually becomes smaller the cavity from top to bottom, and the bottom of cavity is equipped with gasket 3, The gap of 4-6mm is equipped between the gasket 3 and the inner wall of cavity.The shear includes cutting with what punching bucket 1 matched Side half module 6 and drain cap piece 7 positioned at 6 lumen centers of trimming half module, the internal diameter of trimming half module 6 are 5- bigger than the diameter of punching bucket 1 7mm.The inner hole for accommodating and rushing block 4, the big 4-6mm of diameter of the diameter specific impulse block 4 of the inner hole are equipped in the middle part of the drain cap piece 7.It is described The inner cavity top edge arc transition of trimming half module 6, it is convenient to 2 guide-localization of blank.Second jumper bar 8 pushes the first jumper bar 5, the first jumper bar 5 push so that 2 front end of blank rush core 9 and drain cap piece 7 realization rush core 9 shearing and then and blank 2 separate, completion Punching.
With reference to Fig. 2, the workflow of the utility model is as follows:
1, blank 2 is pressed into the tooling being combined by punching bucket 1 and gasket 3;
2, it places to rush block 4 and block 4 will be rushed and is pressed into blank 2;
3, the first jumper bar 5 pushing rushes 4 punching of block to projected depth;
4, blank 2 is gone into the centering that trimming half module 6 realizes product punching position;
5, the second jumper bar 8 and pushing make to rush core 9 and the realization of drain cap piece 7 is rushed the shearing of core 9 and then separated with blank 2, completion punching Hole.
Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects Step is described in detail, it should be understood that being not limited to this foregoing is merely specific embodiment of the utility model Utility model, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should all wrap Containing being within the protection scope of the utility model.
