Specific automobile light-alloy V-type connecting rod more than one piece blanking process are as follows:
Step 1: press ram drives upper big plate 1, loading and unloading material plate 9, the first cutting edge 8, the second cutting edge 10 to be in upper shape
When state, robot grabs 4 V-type connecting rod blanks 12.Light-alloy V-type connecting rod blank 12 is placed on the V-type in lower die 24 by mechanical hand
On connecting rod blank placement location, it is then departed from, press ram drives upper big 1 downlink of plate to drive two the first formed punches 3, and one the
Two formed punches 5, a 6 loading and unloading material plate 9 of third formed punch and the first cutting edge 8,10 downlink of the second cutting edge, loading and unloading material plate 9 are compacted light-alloy V
Type connecting rod blank 12, upper big plate 1, which continues traveling downwardly, drives the first formed punch 3, the second formed punch 5, and third formed punch 6 is continued traveling downwardly, unloaded simultaneously
Material spring 4 is compressed, such first formed punch 3, the second formed punch 5, and third formed punch 6 starts punching and starts to cut light-alloy V-type connecting rod
The work of 12 overlap of blank sweeps away waste material 21 and falls down from lower die 24 until stopping completing to limit.
Step 2: after completing above-mentioned work, upper big 1 uplink of plate drives the first formed punch 3, the second formed punch 5,6 He of third formed punch
9 uplink of loading and unloading material plate, made light-alloy V-type connecting rod blank 12 under 4 compression force of discharging spring that loading and unloading material plate 9 connects from
First formed punch 3, the second formed punch 5 eject in third formed punch 6.Mechanical hand takes light-alloy V-type connecting rod blank 12 away from lower die 24
12 overlap of light-alloy V-type connecting rod blank for leaving, while cutting press machine bottom knockout device effect under by lower connecting plate 18 with it is small

12 overlap of blank completes work by the first lower stripper 13 and the second lower ejection of stripper 14 from lower die 24.Subsequently enter step
One, next group workpiece comes that next working cycles will be carried out.
In some other embodiment, the number of V-type connecting rod is processed every time according to the more of the placement location being arranged in lower die
It is different less, 2,6,8 or 9 type connecting rod blank placement locations also can be set in lower die.
Embodiment 2:
Embodiment 2 and embodiment 1 the difference is that: the first all cutting edges of whole V-type connecting rod blank placement locations
It is to unload under all first lower strippers and second of integrally formed, whole V-type connecting rod blank placement location with the second cutting edge
Flitch is the first lower stripper of integrally formed, whole V-type connecting rod blank placement location and the second lower stripper is one
It is molding.Remaining part and its connection structure are same as Example 1.In embodiment 2 by equipment cutting edge, loading and unloading material plate and under
Stripper is disposed as integrally formed design, reduces the complexity of mold design and manufacture.
As it can be seen that the present invention provides a kind of V-type connecting rod more than one piece die cutting composite die there are multiple V-type connecting rod hairs in lower die
Base placement location can be completed at the same time the trimming of more than one piece V-type connecting rod, rush the compound work of axis hole, improve production efficiency, ensure that production
Stability；And devise shedding mechanism, it may be convenient to carry out discharging, will not cause to scratch workpiece because of demoulding, guarantee
What is worked is safe and reliable.
The embodiment of the present application is described in detail above, specific case used herein to the principle of the application and
Embodiment is expounded, the description of the example is only used to help understand the method for the present application and its core ideas；
At the same time, for those skilled in the art can in specific embodiments and applications according to the thought of the application
There is change place, in conclusion the contents of this specification should not be construed as limiting the present application.
