Direction.
The course of work of one of present invention appliance for releasing single injection material stamping die is:
(1) material piece 31 passes through dual-purpose pin 20 and carries out correcting by dual-purpose pin 20, in punching press ancillary equipment feeder
Effect is lower to carry out self-feeding.Material piece 31 is delivered to cut cells, while shearing punch-pin 6 and moving downward, and stripper plate 30 compresses
Rectangular Spring 25, stripper plate 30 play the role of binder after contacting material piece 31, while dual-purpose pin 20 and round wires under compression downwards
Spring 19 moves downward, and makes to shear punch-pin 6 with the shearing shearing material piece 31 of cavity plate 10 into shear action, the cover plate 31 cut, so
Shearing punch-pin 6 continues traveling downwardly the flatness for completing smoothing movement to guarantee cover plate 31 afterwards.During being somebody's turn to do, stripper plate 30 is led by interior
Column 29 guarantees the precision of shearing punch-pin 6 and forming convax mould 4.
(2) shearing punch-pin 6 completes shearing, completes the cover plate 31 of shearing under the action of push broach 3, passes through 4 guide rails
Guarantee is pushed to forming unit.The design of 3 leading portion of push broach has profiling positioning, facilitates the fixed cover plate 31 of push process.Meanwhile waste material 21
Continue to be fed forward, be sheared by waste material cut-off knife 23, in order to subsequent friction feeding.
(3) upper mold carries out accurate guiding, mold uplink by outer guiding post 22 and outer bush 24 in the upper and lower mould of motion process
When, after inner guiding post 29 completely disengages lower die, cylinder 1 is under machine tool system control, by universal joint 2 and push broach 3, in guide rail 4
Under the action of carry out push cover plate 31, be passed to molding concave die 16, the design of molding concave die 16 has shape fine positioning positioning accuracy
Within 0.01mm.
(4) after completing first time punching press, while cut cells complete shearing motion, forming convax mould 14 and molding concave die
16 pairs of cover plates 34 carry out stile molding, complete blanking cover 13.
(5) in mold uplink, and before cylinder push movement, since forming part (blanking cover 13) and forming convax mould 14 are because of material
Material plastic deformation is bundled together, and when forming convax mould 14 continues uplink, blanking cover 13 starts to contact rigid de- material block 15, make simultaneously
Spring leaf 12 generates elastic deformation, and blanking cover is carried out forced material-removing by the effect of rigid de- material block 15, when blanking cover 13 and forming convax mould
After 14 are kept completely separate, blanking cover 13 is ejected mold cavity under the action of the reseting elasticity of spring leaf 12, completes automatic elastic
Discharging movement (spring leaf is bidirectional arrangements, and Impact direction is parallel to push broach push direction).
One of present invention appliance for releasing single injection material stamping die has technical effect below
1. mold is that either simplex sequence separate unit splices mold, manufacturing development cost is lower than the continuous mould of similar product.
2. single die tool realizes that previous process to subsequent processing feeding, replaces artificial feeding by cylinder pusher.
3. single die tool realizes product discharge by spring leaf elastic force and rigid de- material block, replace artificial feeding.
4. two-step, two single-set operation successful conversions are process single machine continuous operation by mold.
The configuration of the present invention is simple is easy to make, effectively reduces mould development cost, reduces manual operation, artifact
Material carrying etc., reduces the manufacturing cost of stamping parts, improves the overall acceptability rate of stamping parts, while also improving components
The market competitiveness, the value with wide popularization and application.
Above embodiments are only exemplary embodiment of the present invention, are not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can within the spirit and scope of the present invention make respectively the present invention
Kind modification or equivalent replacement, this modification or equivalent replacement also should be regarded as being within the scope of the present invention.
