Abstract
The invention provides a punching pin self-stabilization device of a floating punching pin mold. The punching pin self-stabilization device comprises an upper mounting plate, a pin beating plate, an upper mold plate, a lower mold plate and a lower mounting plate. The pin beating plate and the upper mold plate are adaptively mounted on the upper mounting plate through mounting screws. The lower mold plate is adaptively mounted on the lower mounting plate through mounting screws. Punching pin pieces are adaptively and movably mounted on the upper mold plate. Core convex heads matched with the punching pin pieces are arranged at the upper ends of the punching pin pieces. Concave positions matched with the core convex heads are arranged on the pin beating plate. When the pieces are punched and stressed, the stress faces of the convex heads and the concave positions have the structural characteristics of guide and self-stabilization on punching pin cores, and therefore the floating punching pin structure of the mold keeps unchanged, the deviation problem of floating punching pins is effectively solved, and the aim that the mold is reliable and stable is achieved.
Description
Technical field
The present invention relates to floating type red needle mould applications, particularly relate to the red needle self-stabilization dress of a kind of floating type red needle mould
Put.
Background technology
Printed wiring board itself installs electric components because of carrying to be needed, and generally there is the feature of densely covered insert hole, its
Moulding process, in addition to using the production method of digital control processing, it is simply that uses floating type red needle mould to be processed producing.
Wherein, floating type red needle mould has one-shot forming, the feature that dimensional uniformity is good, so, floating type red needle mould
Tool is more and more to be used by other industry.
Existing floating type red needle mould, the effect of its punch forming process relied primarily between the coordinating of punch and die
Gap.Furthermore, red needle (punch) structure of traditional floating type red needle mould is in quick condition, therefore can occur by randomness
" wander off " image, thus causes fit clearance " to wander off " and form " inclined hole ", and along with the seriality produced, mould is by occurence tendency
Property abrasion, even occur mould damage " stinging mould " phenomenon.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of keep the floating type red needle structure of mould not
Become, effectively solve the red needle self-stabilization device that the floating type red needle of floating type red needle mould " wanders off ".
The goal of the invention of the present invention is achieved in that the red needle self-stabilization device of a kind of floating type red needle mould, including
Upper mounting plate, plate of having an injection, cope match-plate pattern, lower bolster and lower installation board, described in have an injection plate, cope match-plate pattern by install screw adaptation install
On upper mounting plate, lower bolster is installed on lower installation board by installing screw adaptation, and wherein, the upper end of described red needle part is provided with
Associated core plush copper, described in plate of having an injection be provided with the recess matched with core plush copper.
Being optimized according to above-mentioned, during punching circular hole, described red needle part is cylindrical male plug, and red needle plush copper is set to 90 ° of circles
Cone plush copper, described in have an injection 90 ° of tapered recess that plate recess is set to match with core plush copper.
During the circular hole of punching large-size, described red needle part is large-area cylindrical male plug, and core plush copper is set to some
Individual uniform circular cone plush copper, described recess is set to several tapered recess matched with core plush copper.
During punching slot, described red needle part is rectangle core, and core plush copper is set to equilateral triangle plush copper, described
Recess is set to the equilateral triangle recess matched with core plush copper.
During the square opening of punching large-size, described red needle part is large-area rectangle core, if core plush copper is set to
Dry uniform circular cone plush copper, described recess is set to several tapered recess matched with core plush copper.
During the polygonal hole of punching large-size, described red needle part sets for large-area polygon core, core plush copper
For the circular cone plush copper that several are uniform, described recess is set to several tapered recess matched with core plush copper.
Being optimized according to above-mentioned, described core plush copper is one-body molded with red needle part.
The beneficial effects of the present invention is: use the red needle self-stabilization device of this floating type red needle mould, utilize red needle part
The conical surface of the conical surface of termination and plate recess of having an injection, it is achieved the red needle part conical surface centripetence when punching press stress, forms red needle part
Correcting self-stabilization architectural characteristic, thus keep the floating type red needle structure of mould constant, effectively solve floating type red needle and " walk
Problem partially ", reaches the due reliable and stable purpose of floating type red needle mould.
Accompanying drawing explanation
Fig. 1 is the structural representation of present pre-ferred embodiments.
Fig. 2 is the enlarged drawing of A in present pre-ferred embodiments Fig. 1.
Detailed description of the invention
Being explained in detail the present invention below in conjunction with the accompanying drawings, as shown in Fig. 1, Fig. 2 of preferred embodiment, it includes peace
Dress plate 1, plate 2 of having an injection, cope match-plate pattern 3, lower bolster 4 and lower installation board 5.Described plate 2 of having an injection, cope match-plate pattern 3 are adaptive by installing screw 6
Being installed on upper mounting plate 1, lower bolster 4 is installed on lower installation board 5 by installing screw 6 adaptation.Wherein, described cope match-plate pattern 3
On red needle part 7 is installed, the termination of red needle part 7 is provided with core plush copper 8, described in plate 2 of having an injection be provided with and match with core plush copper 8
Recess 9.
In actual applications, floating type red needle mould, during its punching circular hole, described red needle part 7 is cylindrical male plug, core
Plush copper 8 is set to the 90 ° of circular cone plush coppers matched with red needle part 7, and described recess 9 be set to match with core plush copper 8 90 ° are tapered recessed
Position.
When punching slot, described red needle part 7 is rectangle core, and core plush copper 8 is set to match with red needle part 7
Equilateral triangle plush copper, described recess 9 be set to match with core plush copper 8 in equilateral triangle recess.
When the large-area circular hole of punching, square opening, during irregularly-shaped hole, the red needle part 7 no matter selected is cylindrical male plug, or long
Square core, or polygon core, their core plush copper 8 is all set to the circular cone plush copper that several are uniform, and described recess 9 is set to
Several tapered recess matched with core plush copper 8.
And, described core plush copper 8 is one-body molded with red needle part 7.
Summary, when red needle part 7 is in punching press stress, conical surface centripetence has the knot of the self-stabilization of correcting red needle part
Structure characteristic, thus keep the floating type red needle structure of mould constant, effectively solves floating type red needle and " wanders off " problem, reach mould
Due reliable and stable purpose.
