Abstract
The invention discloses an excessive expansion-prevention connection plate expansion die. The excessive expansion-prevention connection plate expansion die comprises an upper die plate, guide sleeves arranged at two sides of the bottom surface of the upper die plate, guide columns, an expansion female die arranged in the middle of the bottom surface of the upper die plate, a fixing plate arranged at the top surface of a lower die plate, an edge turning female die arranged at the upside of the fixing plate, an edge pressing ring arranged inside the edge turning female die, an expansion male die arranged inside the edge pressing ring and the fixing plate, an L type force applying part integrally formed with the outside of the expansion female die, an annular positioning part integrally formed with the L type force applying part, an outer limiting part arranged inside the annular positioning part, and an inner limiting part integrally formed with the upper part of the inside of the expansion female die, wherein the ends of the guide columns are arranged with the guide sleeves, and the other ends of the guide columns are arranged at the lower die plate; and the expansion female die and the expansion male die are movably embedded. According to the excessive expansion-prevention connection plate expansion die, limiting is realized by the outer limiting part inside the expansion female die and the inner limiting part outside the expansion female die, and workpiece scrappage or influence on workpiece quality caused by excessive expansion of the expansion female die is prevented.
Description
Technical field
The present invention relates to a kind of swollen pattern, be specifically related to a kind of anti-swollen pattern of expanded joint contact pin excessively, belong to technical field of mold.
Background technology
Bulging belongs to elongation and is shaped; It is under the effect of mould, forces the thinning and surface area of blank thickness to increase, is called bulging, dull and stereotyped blank carries out bulging and is processed into pcketing with the processing method for stamping obtaining part geometry shape; It relies at the bulging die in the pcketing hole, local of flat board, and deformed area part sheet thickness is thinning, surface area increase realizes; Material during bulging in deformed area can not shift outside deformed area, and the material outside usual deformed area does not also supplement in deformed area, and this bulging becomes pure bulging.During dull and stereotyped blank local bulging, generally all belong to this situation.Bulging belongs to elongation class and is shaped; Bulging Process gathers can not produce Instability wrinkling phenomenon, and surface of the work is very smooth when bulging is abundant; The existing swollen pattern for brace is perfect not enough, and it easily causes undue bulging, causes brace to be out of shape or compromised quality.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the present invention proposes a kind of anti-swollen pattern of expanded joint contact pin excessively, can prevent swollen, available protecting brace safety.
(2) technical scheme
The anti-swollen pattern of expanded joint contact pin excessively of the present invention, comprises cope match-plate pattern, and is arranged at the guide pin bushing of both sides, cope match-plate pattern bottom surface; And the guide pillar that one end and guide pin bushing are installed, its other end is installed in lower bolster; And the swollen type die be arranged in the middle part of cope match-plate pattern bottom surface; And be arranged at the fixed head of lower bolster end face; And the flange die be arranged on the upside of fixed head; And the blank holder be arranged at inside flange die; And the swollen type punch be arranged at inside blank holder and fixed head; Described swollen type punch is mutually embedding with the activity of swollen type die; Also comprise with swollen type die outside the L-type force-applying piece that is made into integration; And the annulus keeper to be made into integration with L-type force-applying piece, and with the outer locating part be arranged at inside annulus keeper; And locating part in being made into integration with swollen type die inside upper part.
Further, described outer locating part is mutually embedding with flange die top.
Further, fit in described annulus keeper time descending and flange die top.
(3) beneficial effect
Compared with prior art, the anti-swollen pattern of expanded joint contact pin excessively of the present invention, swollen type die is chimeric with swollen type punch carries out bulging, undertaken spacing by the outer locating part of swollen type die inner side and outer side and interior locating part, prevent its undue bulging from causing workpiece to be scrapped or workpiece quality is affected, it can improve workpiece quality and operating efficiency.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Detailed description of the invention
The anti-swollen pattern of expanded joint contact pin excessively as depicted in figs. 1 and 2, comprises cope match-plate pattern 1, and is arranged at the guide pin bushing 2 of both sides, cope match-plate pattern bottom surface; And the guide pillar 5 that one end and guide pin bushing are installed, its other end is installed in lower bolster 6; And the swollen type die 3 be arranged in the middle part of cope match-plate pattern bottom surface; And be arranged at the fixed head 7 of lower bolster end face; And the flange die 4 be arranged on the upside of fixed head; And the blank holder 9 be arranged at inside flange die; And the swollen type punch 8 be arranged at inside blank holder and fixed head; Described swollen type punch 8 is mutually embedding with the activity of swollen type die 3; Also comprise with swollen type die outside the L-type force-applying piece 10 that is made into integration; And the annulus keeper 11 to be made into integration with L-type force-applying piece, and with the outer locating part 12 be arranged at inside annulus keeper; And locating part 13 in being made into integration with swollen type die inside upper part.
Wherein, described outer locating part 12 is mutually embedding with flange die 4 top.Described annulus keeper 11 time descending is fitted with flange die 4 top.
The anti-swollen pattern of expanded joint contact pin excessively of the present invention, after being led, drives swollen type die descending by actuating unit by guide pillar, and it is chimeric with swollen type punch; Brace, by blank holder flexible limit, can be protected it, and conveniently carry out bulging; Can carry out spacing to brace and swollen type die by flange die, the brace sound construction after its processing, stability is high.
The anti-swollen pattern of expanded joint contact pin excessively of the present invention, swollen type die is chimeric with swollen type punch carries out bulging, undertaken spacing by the outer locating part of swollen type die inner side and outer side and interior locating part, prevent its undue bulging from causing workpiece to be scrapped or workpiece quality is affected, it can improve workpiece quality and operating efficiency.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
