Description of drawings
Fig. 1 carries out the structural representation of first step processing for the utility model;
Fig. 2 carries out the structural representation of second step processing for the utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1:
As shown in Figure 1, 2, present embodiment by pediment stick 1, backlash rod 2, securing member 3, die main body 4, die 5, ejector beam 7, liftout cover 8, on fill up 9, underlay 91, fill up 92 outward, foot pad 93 forms.Be provided with die 5 in the die main body 4,5 one-tenth truncated cone-shaped of die, securing member 3 is threaded with die main body 4, and securing member 3 is fastenedly connected one with die 5 and die main body 4, is provided with liftout cover 8 in the middle of securing member 3 and the die main body 4.The below of liftout cover 8 is provided with pad 9, underlay 91, on fill up 9 and underlay 91 fixing by being arranged on its outer outer pad 92, Dian below is provided with foot pad 93 outside, backlash rod 2 is arranged on that liftout overlaps 8, underlay 91, on fill up in 9.Ejector beam 7 withstands on the below of pad 9, and ejector beam 7 is arranged in underlay 91 and the foot pad 93.Pediment stick 1 is arranged on the top of die 5, and the position is relative with die 5, and pediment stick 1 is provided with pediment stick hole 12 and waste outlet 11.
Backlash rod 2, pediment stick 1, die 5, die main body 4, securing member 3, backlash rod 2, liftout cover 8, on fill up 9, underlay 91, fill up 92 outward, the center of foot pad 93 is on same straight line.
Fig. 1, Fig. 2 are respectively the state diagram of first step processing and the processing of second step, and the first step is a through hole, and remove waste material 10, and waste material 10 is discharged by pediment stick hole 12 and waste outlet 11.Second step was burnishing-in endoporus, elimination vestige.
Each procedure of processing all needs to change suitable pediment stick 1, backlash rod 2 and die 5.The pediment stick of using in second step is not provided with pediment stick hole and waste outlet.Through this two steps processing, just finished the cold-heading fine finishining of piston pin.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.The practical new shape patent of Fan Yiben is conceived equivalence or the simple change that described structure, feature and principle are done, and is included in the protection domain of the new shape patent of this practicality.The new shape person of ordinary skill in the field of this practicality can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from the structure of the new shape of this practicality or surmount the defined scope of these claims, all should belong to this practicality protection domain of shape newly.
