Description

The square washer mould of improvement

The utility model relates to a kind of mould, and condition adjustment such as the shape when particularly relating to a kind of can the making according to square washer, size, decorative pattern change to be used, and more helps the square washer mould of improvement of the convenience of mold repair and mould design.

Square washer is the spare part that belongs to indispensable in motor, electronics industry circle, and the assembling of every facility, lock are paid the scope that function all belongs to its application.Yet the function of packing ring is: (1) can make the screw connector of not making peace directly contact, and makes connector frayed by rotation; (2) when screw on the oversize or screw screw thread place short, when inconvenience maybe can't lock onto the connector surface, use packing ring that easy effect is rapidly arranged; (3) the diagonal angle length of screw terminal is than the hole of connector hour, and available packing ring increases its contact-making surface, to reach the purpose of locking.

Yet because the use of packing ring is frequent, application is extensive, so required quantity is also considerably big, and because of its volume is little, how shape and the various variation of function tool be so manufacture in the mass-produced mode of serialization on making.

See also shown in Fig. 1 and Fig. 2 A, Fig. 2 B, be the schematic diagram of commonly using square washer and vertical view, cutaway view, the aforementioned method for making of commonly using square washer 20, lines 22 shapes for subpunch pressure pad circle 20, treat the lines 22 punching presses subsequent rows punching out central circular hole 24 that finishes, cut off operation after central circular hole 24 punching out finish again to obtain finished product.The aforesaid method for punching of commonly using, be to go punching and cutting off again towards lines moulding line in advance, yet this method is through the punching operation time, because the tension stress of material and cut off the shape that action will destroy the moulding of former institute, cause the forfeiture of washer size precision, highly differed in the lines end angle 261 of four lines 22, make its planarization poor, thereby influence the effect when assembling.Above-mentioned located by prior art will cause to use and go up many shortcoming and drawbacks, and real not satisfactory, simple now Lieque point is as follows:

(1) because the square washer mould is the production model that belongs to progressive press tool, under using for a long time, the subregion of mould is impaired with causing; Under the dimensional requirement of taking packing ring production into account, as if finishing, certainly will put in order the group mould and need making again in size area trimming by a small margin, cause on the die cost and bear greatly.

(2) manufacturing specification of square washer, decorative pattern are considerably many, yet commonly use mould only for the Mold Making of single size and decorative pattern, make corresponding to the packing ring of many specifications (decorative pattern), will not apply to use and cause many group moulds, expensive drawback.

(3) commonly use the program of making square washer, be to go punching and cutting off again towards lines moulding line, yet this method cause the forfeiture of washer size precision in the shape that will destroy the moulding of former institute through punching and when cutting off action in advance, make its planarization poor, thereby influence the effect when assembling.

This shows that still there are many shortcomings in above-mentioned located by prior art, real non-one perfect design, and demand urgently being improved.

This creator is actively improved innovation in view of the existing every shortcoming of above-mentioned located by prior art, after concentrating on studies for many years, finishes the utility model finally.

The purpose of this utility model is, a kind of square washer mould of improvement is provided, this mould can the continuous punching out of four-part form form make packing ring, i.e. one section first punching out endoporus, second section capable punching press lines shape, and the 3rd section trimming endoporus accurate dimension, the 4th section then continues and thrusts finished product, make this four-part form pressing operation, its punching, lines moulding and cut off program, corresponding perforating die, lines shaping mould and shear(ing) die all design the form of burying with independent edge, thereby can produce the packing ring of plurality of specifications decorative pattern, use to satisfy many-side, and do not need many group moulds.
