Abstract
The invention discloses a semi-arc sheet metal part processing device. The semi-arc sheet metal part processing device comprises a lower die plate (1), a fixing plate (2), a bent cavity die (3), a bent terrace die (4), a cutting-off terrace die (6) and a die shank (7). The die shank (7) is mounted inside the die shank hole of a press machine, the fixing plate (2) is connected with the lower die plate (1), the bent cavity die (3) is arranged on the fixing plate (2), the bent terrace die (6) and the bent cavity die (3) are in clearance fit, the bent terrace die (4) comprises a cavity, and the cutting-off terrace die (6) is arranged on the middle point of the curved surface of the bent cavity die (3). The semi-arc sheet metal part processing device has the advantages of being simple in processing operation, high in processing precision, good in processing quality and stability and the like.
Description
Technical field
The invention belongs to field of machining, relate in particular to a kind of device of half arc sheet metal parts processing.
Background technology
Half arc sheet metal parts is common in furniture parts, mechanical outer surface etc., and the demand of processing is large.Common processing mode is to make the processing mold of one and half arcs, one by one processing.But because half arc is asymmetric, often, in the process of stamping machine extruding, cause deformation inhomogeneous, be difficult to reach the requirement on machining accuracy of workpiece.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of device of half arc sheet metal parts processing.
The technical scheme that the present invention takes is:
A device for half arc sheet metal parts processing, comprises that lower bolster 1, fixed head 2, bending die 3, bending punch 4, cut-out punch 6, die shank 7, described die shank 7 are installed in pressing machine die delthyrium, for generation of downward pressure; Described fixed head 2 is connected with lower bolster 1, bending die 3 is positioned on fixed head 2, described bending punch 6 forms intermittently and coordinates with bending die 3, contains a cavity in affiliated bending punch 4, and described cut-out punch 6 is positioned at the curved surface intermediate point of bending die.
Preferred scheme is, the sweep of described bending die, is made up of unloading block, unloading block below, and that places an elastically deformable determines material bar.
Preferred scheme is, the sweep of described bending die 3, is made up of 2 unloading block 5, unloading block 5 belows, and that places respectively an elastically deformable determines material bar 10.
Preferred scheme is, in the cavity of described bending punch 4, to be provided with knockout rod 8, discharge arm 9.
The advantages such as it is simple that the present invention has process operation, and machining accuracy is high, crudy good stability.
Brief description of the drawings
Fig. 1 is the structural representation of apparatus of the present invention.
Detailed description of the invention
Below by embodiment, the present invention is specifically described.
In conjunction with Fig. 1, introduce a preferred embodiment of the present invention.
A device for half arc sheet metal parts processing, comprises that lower bolster 1, fixed head 2, bending die 3, bending punch 4, cut-out punch 6, die shank 7, described die shank 7 are installed in pressing machine die delthyrium, for generation of downward pressure; Described fixed head 2 is connected with lower bolster 1, bending die 3 is positioned on fixed head 2, described bending punch 6 forms intermittently and coordinates with bending die 3, contains a cavity in affiliated bending punch 4, and described cut-out punch 6 is positioned at the curved surface intermediate point of bending die.
Preferred scheme is, the sweep of described bending die, is made up of unloading block, unloading block below, and that places an elastically deformable determines material bar.The sweep of described bending die 3, is made up of 2 unloading block 5, unloading block 5 belows, and that places respectively an elastically deformable determines material bar 10.In the cavity of described bending punch 4, be provided with knockout rod 8, discharge arm 9.
In the time of processing half arc sheet metal parts, in die shank 7 installations and pressing machine die delthyrium, ejector beam pushes up unloading block to concordant with bending die under the effect of press elastic buffer.When work, blank is placed in mould appropriate location slider of punch to start to move down, and first bending punch contacts with plate.Under the acting in conjunction of bending punch, bending die and unloading block, start curved blank, along with moving down of slider of punch, cutting off punch also starts and contacts by the semi-finished product of curved good shape, so bending punch is proofreaied and correct workpiece bending on one side, with the acting in conjunction of cut-out punch, plate is cut into two processing that complete workpiece on one side.
Along with moving on slide block, the dnockout cross bar being loaded in knockout rod and the forcing press in press shank hole bumps against, stripping force passes in discharge arm through knockout rod, by discharge arm, die-cut waste material is released to the die cavity of bending punch, the workpiece meanwhile processing is also ejected the die cavity of bending die by unloading block effect, complete the processing of whole workpiece.
Above-described embodiment is only preferred embodiment of the present invention, not in order to limit the present invention.
