The technical solution of the utility model is：In a kind of turbocharging oil return pipe bending punching, including one end and equipment
The fix bar that is connected of connecting rod, the other end of the fix bar is spaced successively to be hinged with to form catenate first, second
And the 3rd core pulling pearl, the end of end face bottom and the fix bar other end of the first, second core pulling pearl away from the fix bar other end
Face bottom fits to form forniciform inclined-plane when being separately provided for oil return pipe bending between adjacent core pulling pearl.
Further, one end of the fix bar is provided with counterbore, is provided with the counterbore and connecting rod bolt
Screwed hole, the notch for being engaged with spanner is also respectively provided with the front and back sides in the middle part of the fix bar.
Further, one end of the first, second and third core pulling pearl is respectively arranged with the articulated section of projection, and described the
First, the other end of the second core pulling pearl and fix bar is separately provided for the groove that articulated section is stretched into, and the articulated section is stretched into recessed
Realized in groove and through the rotating shaft through articulated section and groove with adjacent core pulling pearl or fix bar be hinged.
Further, the distance between adjacent two rotating shaft is 8mm, the rotating shaft and the hinge hole that is arranged on articulated section it
Between gap be 0.2mm.
Compared with prior art, the utility model has advantages below：The bending punching, is not only simple in structure, and
It is conveniently used for turbocharging oil return pipe to be bent, ensureing the knee of turbocharging oil return pipe will not deform；Make simultaneously
Make simply, cost is low.

Embodiment
For features described above and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below, but the utility model is not limited to this.
Referring to figs. 1 to Fig. 3
A kind of turbocharging oil return pipe bending punching, including the fix bar 10 that one end is connected with the connecting rod in equipment,
The other end of the fix bar be spaced successively be hinged with to form catenate first core pulling pearl 20, the second core pulling pearl 30 and the 3rd is taken out
Core pearl 40, the end face bottom of end face bottom and the fix bar other end of the first, second core pulling pearl away from the fix bar other end
Fit to form forniciform inclined-plane 21,31,11 between adjacent core pulling pearl when being separately provided for oil return pipe bending.The punching
Maximum angle of bend is 90 °.The angle of the fix bar, the inclined-plane of the first core pulling pearl and the second core pulling pearl and horizontal plane can be according to
Secondary is 70 °, 72 °, 75 °.
In the present embodiment, one end of the fix bar is provided with counterbore 12, is provided with the counterbore and connecting rod phase spiral shell
The screwed hole 13 connect, the notch 14 for being engaged with spanner is also respectively provided with the front and back sides in the middle part of the fix bar,
It is engaged when being installed so as to punching with spanner, rotates whole punching.
In the present embodiment, one end of the first, second and third core pulling pearl be respectively arranged with projection articulated section 22,
32nd, 42, groove 23 that the other end of the first, second core pulling pearl and fix bar is separately provided for stretching into articulated section, 33,
15, the articulated section is stretched into groove and realized through the rotating shaft 50 through articulated section and groove and adjacent core pulling pearl or fix bar
It is be hinged, so as to the rotation of core pulling pearl.
In the present embodiment, the distance between adjacent two rotating shaft is 8mm, the rotating shaft and the hinge hole being arranged on articulated section
Between gap be 0.2mm, so as to ensure that oil return pipe ensures 90-degree bent in bending.
The application method of the punching：Connecting rod bolt on one end and bender of fix bar is completed into the bending punching
Fixation；The turbocharging oil return pipe for treating bending is nested with bending punching, whirlpool is promoted by the pushing mechanism on bender
Wheel supercharging oil return pipe the other end turbocharging oil return pipe is bent to required angle, by turbocharging oil return pipe after bending from
In bending punching, take off and complete the bending of turbocharging oil return pipe and ensure that turbocharging oil return pipe will not occur in knee
Deformation.
The foregoing is only preferred embodiment of the present utility model, it is all done according to present utility model application the scope of the claims it is equal
Deng change and modification, it should all belong to covering scope of the present utility model.
