Abstract
The utility model discloses the continuous fine stamping die of gear box reverse gear shift fork part, it comprises cope match-plate pattern, upper padding plate, upper mounted plate, breach drift, press shaping die punch, blanking punch-die, gear ring pressing plate, upper transmission rod, lower bolster, lower bolster, die, back-pressure plate and lower transmission rod; Upper padding plate is arranged at the surface that cope match-plate pattern is relative with lower bolster, and lower bolster is arranged at the surface that lower bolster is relative with cope match-plate pattern; Breach drift, press shaping die punch and blanking punch-die are installed on upper padding plate; Upper transmission rod is arranged on cope match-plate pattern, and lower transmission rod is arranged on lower bolster; Cavity die camber cutting edge and blanking punch-die curved surface cutting edge are Z-shaped curved surface.Die of the present utility model is corresponding Z-shaped curved surface with the cutting edge of blanking punch-die, when essence is cut out in a state of excitement, the stressed of stamping-out line starts simultaneously, and part is just subject to uniform blanking pressure like this, and then ensures that random distortion does not appear in curve form and the size of part.
Description
Technical field
The utility model relates to a kind of fine blanking die, particularly a kind of continuous fine stamping die of automobile gearbox back fork part.
Background technology
As shown in Figure 1, vent A position is Z-type bending to design of part shape, and requires side bright and clean, and profile is certain curve shape.If adopt general forming technology, as blanking-press-bending, or in a secondary continuous mould, adopt and rush in advance technical gaps, bend, blanking.So, part is after bending, and near bending, material outwards flows out, and forms little bulge, also easily occurs that bending crack, size are not easy to control simultaneously, maybe can not meet product function requirement.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of continuous fine stamping die of gear box reverse gear shift fork part, it can in a secondary mould, realize bending forming and essence is rushed blanking, to have solved efficiency and the unsettled problem of product parts precision quality.
For achieving the above object, the utility model adopts following technical scheme:
The continuous fine stamping die of gear box reverse gear shift fork part, it comprises cope match-plate pattern, upper padding plate, upper mounted plate, breach drift, press shaping die punch, blanking punch-die, gear ring pressing plate, upper transmission rod, lower bolster, lower bolster, die, back-pressure plate and lower transmission rod; Cope match-plate pattern and lower bolster are oppositely arranged, and upper padding plate is arranged at the surface that cope match-plate pattern is relative with lower bolster, and lower bolster is arranged at the surface that lower bolster is relative with cope match-plate pattern; Breach drift, press shaping die punch and blanking punch-die are installed on upper padding plate by upper mounted plate; Die is arranged on lower bolster by lower bolster, and gear ring pressing plate is relative with die; Upper transmission rod is arranged on cope match-plate pattern, and lower transmission rod is arranged on lower bolster; Cavity die camber cutting edge and blanking punch-die curved surface cutting edge are Z-shaped curved surface.
Gear ring pressing plate is the curved-surface structure corresponding with die with back-pressure plate at blanking station.
The beneficial effects of the utility model:
The principle of utilizing essence to rush three-dimensional compressive stress in a secondary mould, stamping before, first material is implemented the clamping of triaxial pressure stress, to control the mobile direction of material, directly complete the operation that press shaping die and curved surface essence are rushed blanking.Part side (shear surface) is vertical with upper lower plane, appearance profile shape and the requirement of size conforms product function, and without uncontrollable little bulge and crackle, product percent of pass is high.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model part;
Fig. 2 is the schematic diagram of mould in the utility model.
Wherein: 1, cope match-plate pattern; 2, upper padding plate; 3, upper mounted plate; 4, breach drift; 5, press shaping die punch; 6, blanking punch-die; 7, gear ring pressing plate; 8, upper transmission rod; 9, lower bolster; 10, lower bolster; 11, die; 12, back-pressure plate; 13, lower transmission rod.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 2, for the continuous fine stamping die of gear box reverse gear shift fork part of the present utility model, it comprises cope match-plate pattern 1, upper padding plate 2, upper mounted plate 3, breach drift 4, press shaping die punch 5, blanking punch-die 6, gear ring pressing plate 7, upper transmission rod 8, lower bolster 9, lower bolster 10, die 11, back-pressure plate 12 and lower transmission rod 13.Cope match-plate pattern 1 is oppositely arranged with lower bolster 9.Upper padding plate 2 is arranged at the surface that cope match-plate pattern 1 is relative with lower bolster 9.Lower bolster 10 is arranged at the surface that lower bolster 9 is relative with cope match-plate pattern 1.Breach drift 4, press shaping die punch 5 and blanking punch-die 6 are installed on upper padding plate 2 by upper mounted plate 3.Die 11 is arranged on lower bolster 9 by lower bolster 10.Gear ring pressing plate 7 is relative with die 11.Upper transmission rod 8 is arranged on cope match-plate pattern 1.Lower transmission rod 13 is arranged on lower bolster 9.Wherein, die 11 curved surface cutting edges and blanking punch-die 6 curved surface cutting edges and spares bend shape adapt, and are Z-shaped curved surface, and are different from conventional stamping-out cutting edge (plane cutting edge).Gear ring pressing plate 7 is suitable with spares bend shape.Back-pressure plate 12 adapts with die 11 blade shapes.
In forming process, mould closure, gear ring pressing plate 7 is implemented to clamp to material with die 11, and the interior back-pressure plate 12 of die 11 supports the material within die 11 cutting edge scopes, bending forming punch 5, the downward stamping stamping-out of blanking punch-die 6 with curved surface; Mould is opened, and back-pressure plate 12 ejects part in die 11, and gear ring pressing plate 7 is deviate from billot waste material from blanking punch-die 6, and part is blown.
In this mould, die 11 is corresponding Z-shaped curved surface with the cutting edge of blanking punch-die 6, and when essence is cut out in a state of excitement, the stressed of stamping-out line starts simultaneously, part is just subject to uniform blanking pressure like this, and then ensures that random distortion does not appear in curve form and the size of part.Gear ring pressing plate 7 becomes the curved-surface structure corresponding with die 11 at blanking station also respective design, to meet the fixture requirement to material.Back-pressure plate 12 blanking station be also designed to die 11 with respect to curved-surface structure, to meet after stamping-out completes, part can be ejected.
The utility model, the principle of utilizing essence to rush three-dimensional compressive stress in a secondary mould, stamping before, first material is implemented the clamping of triaxial pressure stress, to control the mobile direction of material, directly complete the operation that press shaping die and curved surface essence are rushed blanking.Part side (shear surface) is vertical with upper lower plane, appearance profile shape and the requirement of size conforms product function, and without uncontrollable little bulge and crackle, product percent of pass is high.
To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
