Abstract
The invention discloses a stamping die for retaining rings for holes. The stamping die comprises a stamping female die and a stamping male die, wherein an abrasion-resistant insert is arranged in an easy-to-abrade position of the stamping female die, the stamping female die and the stamping male die are matched for use, and the abrasion-resistant insert is located in a position where the stress exerted on the die is largest during machining of the retaining rings for the holes, so that the abrasion resistance of the easy-to-abrade position of the die is improved, the maintenance cost of the die is saved, frequent replacement of the die due to local abrasion is not required, the service life of the whole die is prolonged, and the machining benefit is increased.
Description
Technical field
The present invention relates to back-up ring processing technique field, relate in particular to the back-up ring diel of a kind of hole.
Background technology
The Main Function of back-up ring is the cast parts that are fastened on axle, can prevent from being contained in other part plaies on axle, belongs to a kind of securing member, is conventional machine components.In actual production process, back-up ring adopts die stamping mode manufacture conventionally.In punching course, due to the special shape of back-up ring, easily produce wedge angle burr in the incision of mould, the wearing and tearing of mould are increased, reduced the service life of mould, thereby, need to regularly replace mould, so that processing cost increases.
Summary of the invention
For solving the technical problem existing in background technology, the present invention proposes the back-up ring diel of a kind of hole, without because of frequently mold exchange more of concentrated wear, extends the service life of mould, raising processing benefit.
A kind of hole back-up ring diel that the present invention proposes, comprises stamping cavity die and punching press punch;
In stamping cavity die, be provided with the annular groove for punching hole back-up ring workpiece, annular groove has preset width W, and annular groove has two radial indent to center of circle direction depression near a side in its center of circle, the central angle of the circular arc between two radial indent is a, 15 °≤a≤45 °, annular groove is provided with dismountable arc away from a side in the center of circle and inserts, arc insert and two radial indent between arc position relative, the central angle that arc is inserted is b, b >=a, it is L1 at the width on tangential that arc is inserted away from annular groove one side, it is L2 at the width on tangential that arc is inserted near annular groove one side, L1>L2,
Punching press punch coordinates with stamping cavity die.
Preferably, radial indent rounding off.
Preferably, arc is inserted and annular groove rounding off.
Preferably, arc is inserted and is arranged on stamping cavity die by interference fit.
Preferably, the arc surface of inserting is provided with wear-resistant coating.
In the present invention, the hole proposing back-up ring diel, due to the shape of workpiece, easily there is concentrated wear in mould, by wear-resisting inserting is set in unitary mould, use in back-up ring process wear-resisting inserting in the stressed maximum of mould in hole, thereby improve the anti-wear performance of mould position easy to wear, save mold repair cost, therefore, without because of frequently mold exchange more of concentrated wear, extend the service life of unitary mould, improve processing benefit.
Brief description of the drawings
Fig. 1 is the structural representation of the stamping cavity die of a kind of hole back-up ring diel that proposes of the present invention.
Fig. 2 is the structural representation of the punching press punch of a kind of hole back-up ring diel that proposes of the present invention.
Detailed description of the invention
As depicted in figs. 1 and 2, Fig. 1 is the structural representation of the stamping cavity die of a kind of hole back-up ring diel that proposes of the present invention, and Fig. 2 is the structural representation of the punching press punch of a kind of hole back-up ring diel of proposing of the present invention.
See figures.1.and.2, a kind of hole back-up ring diel that the present invention proposes, comprises stamping cavity die 1 and punching press punch 2;
In stamping cavity die 1, be provided with the annular groove 11 for punching hole back-up ring workpiece, annular groove 11 has preset width, and annular groove 11 has two radial indent 12 to center of circle direction depression near a side in its center of circle, the central angle of the circular arc between two radial indent 12 is a, 15 °≤a≤45 °, radial indent 12 rounding ofves, annular groove 11 is provided with dismountable arc away from a side in the center of circle and inserts 13, arc 13 surfaces of inserting are provided with wear-resistant coating, arc insert 13 by interference fit be arranged on stamping cavity die 1 and with annular groove 11 rounding ofves, arc insert 13 and two radial indent 12 between arc position relative, insert 13 central angle of arc is b, b >=a, it 13 is L1 away from annular groove 11 1 sides at the width on tangential that arc is inserted, it 13 is L2 near annular groove 11 1 sides at the width on tangential that arc is inserted, L1>L2,
Punching press punch 2 coordinates with stamping cavity die 1.
In specific implementation process, the insert central angle a of the circular arc between 13 central angle b and two radial indent 12 of arc equates, and equals 30 °.
Radial indent 12 rounding ofves, arc insert 13 with annular groove 11 rounding ofves, ensure the hole machining accuracy of back-up ring of processing.
Arc is inserted and 13 is arranged on stamping cavity die 1 by interference fit, and arc 13 surfaces of inserting are provided with wear-resistant coating, ensure arc insert 13 with the accuracy that coordinates of stamping cavity die 1, and improve arc and insert service life of 13.
In the present embodiment, the hole proposing back-up ring diel, due to the shape of workpiece, easily there is concentrated wear in mould, by wear-resisting inserting is set in unitary mould, use in back-up ring process wear-resisting inserting in the stressed maximum of mould in hole, thereby improve the anti-wear performance of mould position easy to wear, save mold repair cost, therefore, without because of frequently mold exchange more of concentrated wear, extend the service life of unitary mould, improve processing benefit.
The above; it is only preferably detailed description of the invention of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
