A kind of mold suitable for producing movable contact spring
Technical field
The utility model relates to mold manufacture field, in particular to a kind of mold suitable for producing movable contact spring.
Background technique
Movable contact spring mostly uses the conductive materials such as T2 copper to make as conducting element.In existing production, punching press is mostly used Part, mass production.In the production of specific mold, have production movable contact spring by single die, need thick punch extermal form and hole --- Rushing step --- fine shape and hole need three process, need three secondary molds that could complete the processing of stamping parts, cost phase To higher, production efficiency is low, it is difficult to and meet the needs of stamping parts mass production, and in three process, need to be positioned three times, There are unavoidable position errors, will lead to Product Precision and are difficult to ensure;And in process of production, it needs to remove back and forth three times Fortune, it is die-filling three times, increase labour, long-time operation employee's fatiguability.
Utility model content
The technical problems to be solved in the utility model: purpose of the utility model is to solve it is in the prior art not Foot, providing one kind can be with punching precision height, and primary feed can the stamping forming mold for being suitable for producing movable contact spring.
The technical solution of the utility model includes: a kind of mold suitable for producing movable contact spring described in the utility model, described Movable contact spring includes step piece, through-hole and card slot, and the mold includes mould bases, along the die feeding direction, is successively arranged trimming Mould, bender, through-hole fine blanking die and molding blanking die;Mold plate side to be processed, the folding is arranged in the edger Curved mould and edger are in same level direction;The molding blanking die cuts off the plate in the vertical direction.
It further, further include location hole punch die and shop bolt.
Further, the location hole punch die is arranged in plate two sides;Along the die feeding direction, the location hole Punch die is arranged between the edger and bender.
It further, further include the thick punch die of through-hole and the thick punch die of card slot;Along the die feeding direction, the through-hole is thick Punch die and the thick punch die of card slot are arranged before through-hole fine blanking die.
It further, further include the thick punch die of through-hole and the thick punch die of card slot;Along the die feeding direction, the through-hole is thick Punch die and the thick punch die of card slot are arranged before the bender.
Further, the bender includes first Bending Mould and pressure maintaining molding die.
Further, the molding blanking die is equipped with card slot fine cut mouth.
The utility model compared with prior art the utility model has the advantages that due in a pair of molds, be equipped with edger, bending Mould, through-hole fine blanking die and molding blanking die complete the production of movable contact spring by four stations, without manually carrying out in machinery compartment Workpiece handling, localization process;Location hole punch die and shop bolt are equipped between edger and bender, it is complete in edger trimming At rear progress location hole punching press, and the positioning pin for being equipped with cooperation location hole is fixed, guarantees the accurate positioning of subsequent punching press, ensures mold The stability of production;It is stamped and formed out twice in through-hole and card slot, Product Precision is high, and surface quality is good.It is cut in edger Bian Hou can eliminate existing internal stress after just Bending Mould bending, guarantee Product Precision through pressure maintaining molding die.

Specific embodiment
In order to deepen the understanding of the utility model, below we will the utility model is described in further detail in conjunction with attached drawing, The embodiment is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
As Fig. 1-Fig. 4 shows a kind of embodiment suitable for producing the mold of movable contact spring of the utility model, wherein figure Mould bases in 4, comprising: upper die holder 91, upper padding plate 92, upper clamp plate 93, baffle plate 94, stripper plate 95, lower template 96, lower bolster 97, Lower die holder 98, lower cushion block 99 and lower de- plate 100.
As shown in Figures 1 to 3, it along the die feeding direction, is successively arranged and mold 1 side of plate to be processed is set Edger 2, the location hole punch die 3 that 1 two sides of plate are set and the positioning pin with the punching cooperation on plate 1 of location hole punch die 3 Nail 31, the thick punch die 4 of through-hole and the thick punch die 41 of card slot, first Bending Mould 5, pressure maintaining molding die 6, through-hole fine blanking die 7 and molding are fallen Expect mould 8.
Working principle of the utility model is: in conjunction with attached drawing 1-4, plate 1 after entering mold, first through edger 2 cut off to Bending part 10, then located punch die 3 carries out rushing location hole 11, later each station, is designed with cooperation location hole 11 and is determined The shop bolt 31 of position;The thick punch die 4 of via through holes and the thick punch die 41 of card slot later, slightly go out know a little about hole 12 and thick card slot 13 respectively, It is handled through first Bending Mould 5, obtains just step piece 14, then through pressure maintaining molding die 6, obtain molding step piece 15;Then by Through-hole fine blanking die 7 is punched out, and is formed through-hole 16 on plate 1, is finally carried out last punching press by molding blanking die 8, will form Movable contact spring 17 is separated from plate 1.
