Abstract
A cold stamping die comprises an upper die base, a die shank, a base and a cavity die; a punch is fixedly installed on the die shank through a first fixing plate; the cavity die is fixedly installed on the base through a second fixing plate; a shank portion of the punch and the cavity die are in identical conicity; taper holes are formed in the first fixing plate and the second fixing plate; central axes of the punch and the cavity die are coincided. According to the cold stamping die, the punch shank and the cavity die are designed to be in unified standard conicity and matched with taper holes of the fixing plates, efficiencies for replacing the punch and the cavity die are improved, and a same set of die base and fixing plates can be applied to punches and cavity dies in different size and different shapes.
Description
Technical field
A kind of cold punching die of the present invention.
Background technology
At present, the drift of diel of the prior art and the die overwhelming majority are flange, riveted joint, gummed, and tightening or global design cannot rapid interchangeables, processed complex simultaneously, waste of material.
Summary of the invention
A kind of cold punching die of the present invention, drift shank and Die Design are unified standard tapering and coordinate with fixed head taper hole.Improve the efficiency of changing drift and die, the drift of different size, shape and die can share same set of die holder and fixed head.
Above-mentioned purpose of the present invention is to realize by such technical scheme: a kind of cold punching die, comprises upper bolster, die shank, base, die; Die shank is installed with drift by the first fixed head, and die is fixedly mounted on base by the second fixed head.The shank of described drift is identical tapering with die, and described the first fixed head, the second fixed head are provided with taper hole.
The taper hole central axes of the central axis of described drift, die and the first fixed head, the second fixed head.
Described the first fixed head is connected with die shank by the first connecting bolt.
Described the second fixed head is connected with base by the second connecting bolt.
A kind of cold punching die of the present invention, compares with die with the drift of conventional global design for the drift and the die material that have special substance requirement, can save 300% even more.Improve the efficiency of changing drift and die, the drift of different size, shape and die can share same set of die holder and fixed head simultaneously.
The shank of drift and Die Design are unified standard tapering coordinating with the taper hole of punch fixing plate and die block, make its assembling more succinct, and material is more saved, and has improved work efficiency.
Accompanying drawing explanation
Fig. 1 is cold punching die structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of cold punching die, comprises upper bolster 1, die shank 2, base 10, die 9.Fastening bolt 3 is fixed on die shank 2 on upper bolster 1, and die shank 2 is installed with drift 6 by the first fixed head 5, and die 9 is fixedly mounted on base 10 by the second fixed head 8.The shank of described drift 6 is identical tapering with die 9, and described the first fixed head 5, the second fixed head 8 are provided with taper hole.The taper hole central axes of the central axis of described drift 6, die 9 and the first fixed head 5, the second fixed head 8.Described the first fixed head 5 is connected with die shank 2 by the first connecting bolt 7.Described the second fixed head 8 is connected with base 10 by the second connecting bolt 13.Base 10 is fixedly mounted on work bench of punch press 11 by the 3rd connecting bolt 12.
Implementation step:
When use, the first connecting bolt 7 on dismounting the first fixed head 5, changes required drift 6, forms punch.Drift 6 compresses by tapering, and uses the 4th connecting bolt 4 that the drift assembling 6 is fixedly connected with die shank 2 with the first fixed head 5.Due to die shank 2 and upper bolster 1 assembled in advance fastening, now only need to check guarantee fastening firm.
Take same method dismounting die 9, change the die supporting with drift 9, be fixed on base 10, check tightening, then Correction Die, guarantees that with clearance gauge inspection the gap of drift 6 and die 9 peripheries meets the requirements, and can start processing.
