By taking the processing of NKR light truck back axle oil pipe intermediate plates bearing as an example：
NKR light truck back axle oil pipe intermediate plate bearing blanking-bendings-convex point pressing process is compound and once makes answering for two pieces simultaneously
Matched moulds tool is arranged on 63T forcing presses by the mounting means of common diel.
Can be directly used in after such NKR light truck back axle oil pipe intermediate plate bearing blanking procedure blanking-bending of composite die-
Convex point pressing Compound Machining, step are as follows：
1st step：A kind of described oil pipe intermediate plate bearing blanking-bending-convex point pressing process is compound and once make simultaneously
The composite die of two pieces is arranged on 63T forcing presses；
2nd step：Oil pipe intermediate plate carrier strip material after blanking procedure is placed on guide plate 13, and had good positioning with pin stop 14
Billot side end face and front end face；
3rd step：Forcing press is started, cope plate 2 is run downwards with lathe upper table, and blanking die 10 exists with guide plate 13
Billot is first compressed under the pressure effect of discharging rubber 17, then blanking die 10, which moves downward, first completes workpiece with compound die 18 and fall
Material process, it is that bending punch-pin 11 and compound die 18 complete workpiece bows process again then to continue to move downward, impressing red needle 12 with
Compound die 18 completes workpiece convex point pressing process；
4th step：After the processing of workpiece blanking-bending-convex point pressing, the top half return of forcing press top shoe driven mold,
Then forcing press upper table knock-out mechanism drives and beats the slide downward of bar 3, makes bar 3 and drives the slide downward of block hitting 5, block hitting 5 drives
The slide downward of knockout rod 7 gets workpiece, and guide plate 13 unloads dropping material waste material under the active force of discharging rubber 17；
5th step：Repeat step 2 arrives the operation of step 4, carries out the making of lower two pieces workpiece.
NKR light truck back axle oil pipe intermediate plates bearing uses blanking-bending-convex point pressing composite die and combination process and once same
When make two pieces technique after, the relative dimensions such as blanking, bending, convex point pressing are in the margin of tolerance.Sustainable stabilization ensures NKR
Light truck back axle oil pipe intermediate plate bearing reaches product drawing design requirement.Mould uses guide pillar, the guide pin bushing in automatic Correction Die gap
