The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 3-4, fine blanking die for a kind of boss nutplate of the present utility model moulding, comprise cope match-plate pattern assembly, be positioned at the lower bolster assembly of cope match-plate pattern assembly below, be fixed on the die socket 8 of lower bolster assembly top, the holding pad 6 that also die socket 8 moves up and down relatively between cope match-plate pattern assembly and lower bolster assembly, in the mode that can move up and down, be inserted on cope match-plate pattern assembly and for supporting the transmission rod 2 of holding pad 6, be inserted on lower bolster assembly and its anti-push rod 11 moving up and down relatively, be arranged on cope match-plate pattern assembly and its extruding drift 1 moving up and down relatively, the cooperation of described holding pad 6 and die socket 8 is for the clamping to workpiece 7, described holding pad 6 is provided with the through hole passing for extruding drift 1, described die socket 8 is provided with the Reentrant Cavity 15 passing for pushing drift 1 and anti-push rod 11, the center line of described extruding drift 1, the center line of anti-push rod 11, the center line of Reentrant Cavity 15 is coaxial setting, and be all with the center line of transmission rod 2 setting of staggering.Die socket 8 comprises the boss die 13 being inserted in die socket 8, and Reentrant Cavity 15 is formed on boss die 13.
The present embodiment can be by workpiece 7 extrusion packings to the surrounding space of Reentrant Cavity 15 by moving downward of drift 1 of extruding, and moving upward of anti-push rod 11 can be withstood workpiece 7, effectively prevent that workpiece 7 pressurizeds from producing plastic deformation, after Reentrant Cavity 15 is filled completely, extruding drift 1 continues to move downward, the anti-top power that anti-push rod 11 provides is less than extruding force, anti-push rod 11 moves downward, under the continuation extruding of extruding drift 1, complete the punch work at boss face place, guarantee preferably boss plane after moulding and the flatness of lateral surface, significantly cut down finished cost, increase work efficiency significantly.
Preferably, be fitted with its guide rod moving up and down 14 relatively on described cope match-plate pattern assembly, the bottom of described guide rod 14 is connected with holding pad 6.The setting of guide rod 14, can facilitate moving up and down of holding pad 6.
Preferably, described transmission rod 2 provides power by extraneous upper cylinder, and described anti-push rod 11 provides power by the lower oil cylinder in the external world, and described extruding drift 1 provides power by extraneous cylinder.Under the effect of upper cylinder, lower oil cylinder and cylinder, fully guarantee the motion-promotion force of transmission rod 2, anti-push rod 11 and extruding drift 1.
Preferably, described cope match-plate pattern assembly comprises cope match-plate pattern body 3, be fixedly connected on the upper padding plate 4 of cope match-plate pattern body 3 belows, be fixedly connected on the fixed head 5 of upper padding plate 4 belows, and described extruding drift 1 is arranged on fixed head 5; Described lower bolster assembly comprises lower bolster body 10, is fixedly connected on the lower bolster 9 of lower bolster body 10 tops.
Preferably, described lower bolster assembly is provided with for the interspersed chamber of anti-push rod 11, and described chamber comprises upper chamber's section and lower chambers section, and the diameter of the cross section of described upper chamber section is greater than the diameter of the cross section of lower chambers section; On described anti-push rod 11, be formed with limiting section, between described limiting section and upper chamber's section diapire, be provided with spring 12.Limiting section can carry out spacing effectively to the motion of anti-push rod 11, the setting of spring 12 can facilitate the Rapid reset work of anti-push rod 11.
Specific works process of the present utility model is:
1, charging: after workpiece 7 places, upper cylinder drives transmission rod 2 to move downward, and holding pad 6 and die socket 8 are tightly clamped workpiece 7.
2, extruding boss forming: after workpiece 7 clamps completely, air cylinder driven extruding drift 1 moves downward, start extruding, the pressure that now anti-push rod 11 transmits by lower oil cylinder, workpiece 7 downsides are firmly withstood, and anti-top power is larger than the pressure of 7 material plasticity distortion of compression artifact, so in the early stage extrusion process, anti-push rod 11 does not move downward, and the Reentrant Cavity 15 that workpiece 7 is filled die socket 8 by the effect of extruding drift 1 forms boss.
3, punching: when workpiece 7 has been filled after the Reentrant Cavity 15 of die socket 8, the deformation drag of now workpiece 7 extruding increases, the anti-top power that anti-push rod 11 provides is less than extruding force, and anti-like this push rod 11 starts to move downward, and the extruding action of extruding drift 1 starts to become punching action.Extruding drift 1 continues to move downward, and completes the punch work at boss face place, and last punched scrap is the thick gross weight of the about 0.8mm of one deck.
4, the material returned: after step 3 completes, extruding drift 1, transmission rod 2 and anti-push rod 11 start to reset, holding pad 6 unclamps shaping workpiece 7, anti-push rod 11 ejects the waste material in shaping workpiece 7, by the air nozzle on lathe, waste material is blown away, shaping workpiece 7 is sent the blanking that completes again profile to next work step to again.
The utility model is by fine blanking die, can be on smart impact machine once property mold the boss size that meets drawing requirement, and because boss is disposal molding, avoided producing and drawn fold, well guaranteed the screw strength of product.The utility model can be realized stable batch production, and speed of production reaches 40/minute, has met preferably the output requirement of 100,000/month.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
