Specific embodiment:
With specific embodiment, the invention will be further described below, referring to Fig. 1-11:
A kind of compact stamping die with the built-in device of inclined wedge, including upper mold 1, lower die 2, upper mold 1 are arranged upper
The upper and lower mould 2 of die holder 3 is arranged on lower die holder 4, and pressure plate 5, the corresponding position of the baseplane of pressure plate 5 are provided in upper mold 1
It is inlaid with more than one pressure plate insert 6, the quantity of pressure plate insert 6 is arranged according to the actual situation.It is flat at the bottom of pressure plate 5
The groove 7 that face and the concave up formation of pressure plate insert 6 match with the shape of part to be processed, in lower die 2 with binder insert 6
Corresponding position is provided with convex block 17, and convex block, which is plugged in groove, positions work piece, corresponding with pressure plate insert 6 in pressure plate 5
Position is provided with re-entrant cavity 8, and interior in re-entrant cavity 8 to keep cam unit, the cam unit includes being mounted on pressure plate 5
On drive block 9, drive block 9 is fixed in pressure plate 5 and moves synchronously with pressure plate 5, is arranged in a Slideslip of drive block 9
There is sliding block 10, and the upper end of sliding block 10 is slidably connected with 11 level of ontology, ontology 11 is installed on the baseplane of upper mold 1, sliding block
10 baseplane, which is provided with, can protrude into the formed punch 12 being punched out in binder insert 6, wherein the bottom end of the sliding block 10 passes through peace
Dress platform 13 is connect with formed punch 12.Pressure plate 5 tips upside down in lower die 2, and upper mold 1 is pushed along pressure plate 5, and sliding block 10 is along drive block
9 slide downwards drive formed punch 11 to move down realization punching.
The present invention be to apart from sheet metal component edge remotely or sheet metal component center is punched out, in advance will be in binder
The corresponding position of plate insert 6 processes the hole that formed punch 11 can be allowed to pass through, and pressure plate insert 6 is small in size, easy to process, can reduce into
This can allow formed punch 11 needing process with five-axis machine tool by pressure plate 5 if groove directly be arranged in pressure plate 5
By hole, processing is inconvenient, and at high cost.
In order to ensure precision, the lateral surface of the pressure plate 5 is provided with pressure plate guide plate 18, and upper mold 1 is led along pressure plate
Plate 18 moves down, and pushes the movement of sliding block 10 to realize puncture motion, upper mold 1 moves up die sinking along pressure plate guide plate 18.
In order to realize that sliding block 10 automatically resets, reset spring, reset spring are provided between the sliding block 10 and ontology 11
Driving is moved and is resetted in the horizontal direction.When pressure plate 5 retracts, drive block 9 is separated with sliding block 10, and reset spring driving is slided
Block 10 resets, in order to carry out movement next time.
In order to guarantee accurate positioning between pressure plate 5 and upper mold 1, the pressure plate 5 passes through pressure plate guide post 14 and upper mold
1 connection.
5 baseplane of pressure plate of the present invention it is diagonal on be provided with the balance weight 1 with conical socket, in lower die 2
Upper corresponding position is provided with the balance weight 2 16 with tapered protrusion, and pressure plate 5 is connected by balance weight 1 and balance weight 2 16
It connects and tips upside down in lower die 2.It can guarantee the capturing position in lower die 2 of pressure plate 5 by the structure of balance weight, facilitate positioning, really
It is accurate to protect 11 position of formed punch.
In view of the actual conditions of fitter assembly, the inner wall of re-entrant cavity 8 of the present invention and the surrounding after cam unit
Between be formed with space convenient for assembly.When pincers worker actual installation, hand-held 12 calibration hole of sliding block 10 and formed punch is needed
Position, so the bottom muscle of pressure plate 5 cannot be too near to inclined wedge around cam unit, will at least guarantee that hand can be stretched down, otherwise can
The difficult situation for causing pincers worker that can not assemble.
Above-described embodiment is only one of presently preferred embodiments of the present invention, and but not intended to limit the scope of the present invention, therefore:
The equivalence changes that all shape, structures under this invention, principle are done, should all be covered by within protection scope of the present invention.
