Height of the knife 7 near the side of bending side 211 of bending groove 21 is less than bending side of the 3rd lower cutter 7 away from bending groove 21
The height of 211 sides.
For convenience of the installation of upper mould 100, in the connected contiguous block 83 in the upper surface of upper die plate 8, the company of being provided with of contiguous block 83
Connect groove 831.
When the present invention is used, upper mould 100 is connected using the connected contiguous block 83 in the upper surface of upper die plate 8 with the drift of punch press,
The lower template 1 of lower mould 200 is connected on the workbench of punch press, and horizontal through hole 411 of the lead frame 10a from locating piece 41 is passed through
And moved between the guide rail 31 and the guide channel 321 of multiple guiding nails 32 along guiding parts 3, when the front end of lead frame 10a
Stop when moving to the second lower cutter 6, then water is stretched into the first locating dowel 42 its lower end under the driving of driver part such as cylinder
In flat through hole 411 and insert the location hole 101a on lead frame 10a lead frame 10a is carried out just positioning；Then, punch press
Drift drives the upper undershoot of mould 100, many second locating dowels 15 of the lower surface of the second upper die plate 9 to insert on lead frame 10a respectively
Multiple location hole 101a lead frame 10a is accurately positioned, while the lower end of many second locating dowels 15 is also inserted respectively
Enter the resigning hole 161 of the upper end of support column 16；Now lead frame 10a is pressed in the upper of lower module 2 by the lower surface of the second upper die plate 9
On end face, then the first upper die plate 8 continues to move down, and bending briquetting 12 is engaged to drawing through the second upper die plate 9 with bending groove 21
Wire frame 10a carries out bending, while the first upper cutter 51 is engaged with the first lower cutter 5 featheredge of lead frame 10a is cut off
I.e. partial cut below a-a lines in accompanying drawing 1, the 3rd upper cutter 71 is engaged lead frame 10a's with the 3rd lower cutter 7
The feathered edges that i.e. lead frame 10a is cut away at c cut away, and then go up and reset is moved on mould 100.
Next, transfered from one place to another under escort in the first locating dowel 42 except lead frame 10a positioning, lead frame 10a again mobile setting away from
From, making lead frame 10a being partially moved at the second lower cutter 6 along a-a lines, the first locating dowel 42 carries out just positioning again, on
The webbing cut-out of lead frame 10a, is just realized one section by the undershoot again of mould 100 i.e. partial cut above a-a lines in accompanying drawing 1
The separation of lead frame 10a, now, the first upper cutter 51 is engaged the thin of next section of lead frame 10a with the first lower cutter 5
Side cuts off, bending briquetting 12 is engaged with bending groove 21 carries out bending and the 3rd upper cutter 71 to next section of lead frame 10a
It is engaged with the 3rd lower cutter 7 being cut away at the next section of c of lead frame 10a.Therefore upper mould 100 is with the lower matched moulds of mould 200 once,
Can be achieved with one section of cutting of lead frame 10a, bending and feathered edges to cut, the production effect that it effectively increases lead frame
Rate.
The above is only a preferred embodiment of the invention, those skilled in the art makees equivalent change by claim
Both fall within the protection domain of this case.
