Abstract
The utility model discloses a kind of improved edge rolling mould, a kind of cold punching die technical field.Specially during workpiece circle rolling, prepressing procedures are added, i.e., workpiece is needed first to be carried out piercing and flanging by the part of edge rolling and head sub-fraction is pressed into a small arc-shaped, then carry out the edge rolling process of next step.So a whole set of flange, precompressed and edge rolling process so that it is more smooth, more attractive that workpiece is processed edge rolling.
Description
Technical field
The utility model is related to machining technology field, more particularly to a kind of improved edge rolling mould.
Background technology
In process of the conventional traditional edge rolling mould to cylindrical workpiece edge rolling, the work of general only flange and edge rolling
Sequence, the part that workpiece is probably needed edge rolling by such job step is directly flattened, and edge rolling can not be completed.
Utility model content
In order to solve the above problems, the purpose of this utility model is to provide a kind of improved edge rolling mould, that is, increases pre-
Press process.Whole processes include：Flange, precompressed and edge rolling.The part that workpiece is wanted edge rolling carries out precompressed, and the top workpiece is micro-
Minute-pressure provides guiding into roundlet arc shape for edge rolling.
The mould is used for to be carried out precompressed processing by edge rolling workpiece, and the mould includes folded spring combination, stripper sliding block, moved back
Feed ring, aftertaste spring, enlarging blade, stripper, mandrel, lower mould；Attacking head is provided with described disc spring combination.When workpiece quilt
When placing correct position, that is, when being placed between stripper sliding block and enlarging blade, when punch press stamping press is applied to attacking head
Press down whole mould, the effect due to gradient after sliding block is encountered by punching material is extruded toward mold center, with enlarging blade
Precompressed circular arc is extruded together.After the completion of prepressing procedures, mould gos up upwards, under the effect of disc spring elastic force regulation overcoat up
Draw, together band moving mandrel, enlarging blade is up exits workpiece, material returned circle promotes sliding block to return to initial position under the action of the spring.
Regulation overcoat is provided with described mandrel.The disc spring for the material returned is provided with outside described regulation overcoat.
Guide pin bushing is additionally provided with outside the edge rolling mould, passes through M5 screw connections between described mandrel and guide pin bushing.Set on mandrel
Semicircle clip is equipped with, the effect of the semicircle clip is to ensure that mandrel and guide pin bushing synchronously extrude small arc-shaped in place.
The enlarging blade is threadedly secured on mandrel by M6 and forms overall.
Described stripper is threadably secured on guide pin bushing by M5.
Brief description of the drawings
Fig. 1 is workpiece piercing and flanging mould a.
Fig. 2 is state after workpiece piercing and flanging.
Fig. 3 is workpiece precompressed circular arc mold b.
Fig. 4 is state after workpiece precompressed circular arc.
Fig. 5 is the edge rolling mould c of workpiece.
Fig. 6 is the state after workpiece circle rolling.
Embodiment
Brief description is made to preferred embodiment of the present utility model below in conjunction with the accompanying drawings.
One workpiece, by fixation, precompressed and edge rolling process, finally can just be processed into required edge rolling workpiece.The set is rolled up
Circle mould adds the mould of precompressed, that is, adds the edge rolling preparatory process of precompressed so that workpiece is being oriented to the guiding of small arc-shaped
Under along edge rolling drift circular arc homogeneous deformation.Such as Fig. 1, the first station is preparatory process of the workpiece before edge rolling, that is, uses punching
Flanging die a goes out flange shape.
State after such as Fig. 2, workpiece piercing and flanging, workpiece now is by edge rolling part perpendicular to plate plane.
Such as Fig. 3, the second station is that workpiece precompressed before edge rolling guides small arc-shaped process, will treat that the workpiece oral area of edge rolling is pre-
It is pressed into guiding small arc-shaped.Mould b is used for to be carried out precompressed processing by edge rolling workpiece, and mould b includes die shoe 1, the material returned
Plate sliding block 2, stripper 3, enlarging blade 4, material returned circle 5, mandrel 7；Regulation overcoat 10 is provided with described mandrel 7, it is described
It is provided with outside regulation overcoat 10 in the disc spring 12 for the material returned, described disc spring 12 and is provided with attacking head 13.When workpiece is put
When putting correct position, that is, when being placed between stripper sliding block 2 and enlarging blade 4, hand pins attacking head 13 so that whole mould
Press down.After the completion of prepressing procedures, under stripper sliding block 2, stripper 5 and stripper mold insert 3 interact, workpiece from this
Separated on mould.
Guide pin bushing 8 is additionally provided with outside edge rolling mould b, is connected between guide pin bushing 8 and mandrel 7 by M5 screws 11.
The enlarging blade 4 is fixed on mandrel 7 by M6 screws 6；Enlarging blade 4 is more securely fixed on mandrel 7,
Enlarging blade 4 is moved with mandrel 7, edge rolling work effectively is carried out to workpiece 16.
M5 screws 11 are additionally provided with described guide pin bushing 8 so that the head of whole guide pin bushing 8 is fixed.
Such as Fig. 4, workpiece is that workpiece top tip portion now is pressed into small arc-shaped shape in advance by the state of precompressed.
Such as Fig. 5,3rd station is that workpiece completes edge rolling process in the presence of edge rolling mould c, i.e., by the workpiece 16 of edge rolling
Carry out edge rolling process.
Such as Fig. 6, workpiece is that by the state of edge rolling, now workpiece majority can be rolled into the state of circle.The volume of workpiece
Sired results sequence is just finally completed.
Finally it should be noted that the foregoing is only of the present utility model is preferable to carry out example, this is not limited to
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For its can still be replaced on an equal basis.It is all within spirit of the present utility model and principle, it is any modification for being made, equivalent
Replace, within protection domain of the present utility model.
