Fig. 2 is the top view after Fig. 1 removes punch assemblies;
In figure: 1-punch assemblies, 11-bending punch, 12-die shank, 13-upper bolster, 14-upper padding plate, 15-fixed head, 2-bending component, 3-die assembly, 31-rolling pivot pin, 32-locating piece, 33-mold insert, 34-locating pin, 35-pushing block, 36-concave template, 36a-gathering sill, 37-liner plate, 38-lower bolster, 39-die shoe, 4-bullet apical organ, 41-push rod.
Detailed description of the invention
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of rolling friction Bending Mould as depicted in figs. 1 and 2, comprise punch assemblies 1, die assembly 3 and play apical organ 4, described die assembly 3 is fixedly mounted on by die shoe 39 and plays on apical organ 4, die shoe 39 is installed with successively lower bolster 38, liner plate 37 and concave template 36; Rolling pivot pin 31 is arranged on mold insert 33, and it is inner to be fixed on concave template 36 together with mold insert 33; Pushing block 35 on described die assembly 3 is installed between left and right mold insert 33, and liner plate 37 is provided with the through hole corresponding with pushing block 35; Described punch assemblies 1 is placed in the top of die assembly 3, and the lower end of bending punch 11 in punch assemblies 1 is corresponding with the pushing block 35 of die assembly 3.Stainless steel bending component 2 makes generation frictional force in bending component 2 surface drive the rolling pivot pin being arranged on mold insert 33 both sides to roll in moving downward in process of bending punch 11, stainless steel bending component 2 dogleg section is contacted by traditional face and is converted into linear contact lay.
Described concave template 36 is also provided with locating piece 32; Described concave template 36 is also provided with the gathering sill 36a corresponding with pushing block 35.Can prevent the gap existed between rolling pivot pin 31 and die mold insert axis of rolling pin-and-hole from affecting the dimensional accuracy of stainless steel bending component 2, what concave template 36 was designed with is designed with targeting part to groove 36a and pushing block 35 and matches.
Described pushing block 35 inside is also fixedly installed locating pin 34, and the upper end of locating pin 34 is higher than the upper surface of pushing block 35.
Push rod 41 on described bullet apical organ 4 runs through lower bolster 38 and die shoe 39 in the below of pushing block 35.Play apical organ 4 and promote pushing block 35 by push rod 41, promote bending component 2 to move upward, the folding surface of part drives rolling pivot pin 31 to rotate under the effect of frictional force simultaneously, and when pushing block 35 releases the upper side of concave template 36 part, whole Forging Process terminates to realize the bending of stainless steel bending component.
Described punch assemblies 1 also comprises die shank 12, upper bolster 13, upper padding plate 14 and fixed head 15, die shank 12 is arranged on upper bolster 13, the downside of upper bolster 13 is fixedly connected with fixed head 15 with upper padding plate 14 successively, and the upper end of described bending punch 11 is fixed on fixed head 15.
The utility model in actual use, mould is arranged on punch press, stainless steel bending component 2 is placed on mould, the movement of locating pin 34 locating element, the rotation of locating piece 32 locating element, when upper die component 1 is descending, part compresses by bending punch 11, promotes pushing block 35 and moves down, and produces simultaneously and rub and drive rolling pivot pin 31 to rotate between bending component 2 and rolling pivot pin 31.In descending process, part bending face and rolling pivot pin 31 are linear contact lay, and contact position constantly changes along part bending face, and when pushing block 35 contacts with lower bolster 38, upper die component 1 stops moving downward, bending component bending and forming.In pushing block 35 motion process, effect due to gathering sill 36a makes pushing block 35 produce skew, recycle the hole on part or set up fabrication hole location, the free degree in restriction " X ", " Y " direction, External Shape is utilized to locate, limit the rotation around " Z " axle, efficiently solve the impact of the gap between rolling pivot pin 31 and pin hole on parts size precision.
