Description
Technical field
The utility model relates to a kind of member slot for small size Rogers plate, particularly the making frock of limiter small size Rogers circuit board component groove.
Background technology
Along with the develop rapidly of microwave industry, high power, high speed, high-frequency, miniaturization become the wind vane of power electronic production development.Use the temperature stability with superior dielectric constant, Rogers's plate that the thermal coefficient of expansion of dielectric constant is very consistent with Copper Foil is used widely at microwave industry as circuit board.Because power electronic product structure size and frequency height are inversely proportional to, along with upwards expanding of product frequency causes coming into operation in a large number of 0201,0402 encapsulating electronic components, the requirement of Rogers's circuit board miniaturization is improved day by day.
For existing a product: according to circuit design requirements, at profile overall size 10mm × 8mm, gauge be 0.254mm Rogers's plate on make 2mm × 0.5mm, dimensional tolerance required precision controls the member slot at 0.03mm.Because spare part outside measurement is minimum, benchmark is determined and clamp difficulty, micro machining center cannot be used to make; Solve according to Dies ' Blanking mode, then according to Sheet Metal Forming Technology principle, initial double-faced clearance Z Z=(6% ~ 8%) × material thickness t when material thickness is less than 1mm of the blanking die of flexible material, and in Rogers's plate thickness 0.254mm situation, obtain punch and female die single-side gap 0.008mm, and carry out in frock making process at usual manner, the existence accumulated due to workpiece resetting, manufactured size and form and position tolerance causes blanking groove gap size to be difficult to ensure.Therefore existing production is generally process by the mode of scalpel hand engraving hollow out under thin framework template, circuit board exists that accurate to dimension difference, border are coarse, burr serious phenomenon, has a strong impact on the electrical quantity index such as product S parameter and the flatness of standing wave in band.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of member slot for small size Rogers plate, and to reach the member slot of accurately processing small size Rogers plate, and processing parts can not be out of shape and be formed the object of burr.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
For a member slot for small size Rogers plate, for assigning circuit board to be produced, it is characterized in that, comprising the upper die and lower die cooperatively interacted; Described upper die and lower die are provided with the identical dowel hole in position, gathering sill and charging conduit; The upper surface of described counterdie is provided with die cavity; The size of described die cavity and circuit board to be produced matches; Also be furnished with the alignment pin matched with described dowel hole and the drift matched with die cavity.
Aforesaid a kind of member slot for small size Rogers plate, is characterized in that, described upper die and lower die are laterally divided into two by same die body blank and make.
Aforesaid a kind of member slot for small size Rogers plate, is characterized in that, the registration tolerance of described upper die and lower die is less than 0.001mm.
Aforesaid a kind of member slot for small size Rogers plate, is characterized in that, the die cavity on described counterdie upper surface adopts precision grinder processing.
Aforesaid a kind of member slot for small size Rogers plate, is characterized in that, the gap of described drift and gathering sill is 0.005mm.
Aforesaid a kind of member slot for small size Rogers plate, is characterized in that, described circuit board to be produced adopts Rogers's plate.
The beneficial effect that the utility model reaches: product structure of the present utility model is simple, design ingenious, be convenient to make small size Rogers plate, overcome because small size Rogers plate rigid deficiency causes clamping and the difficult problem making difficulty, cost of manufacture is low, dimensional accuracy is high, meets the user demand of research and production.
Accompanying drawing explanation
Fig. 1 is an embodiment cross-sectional view of the present utility model;
Fig. 2 is schematic flow sheet of the present utility model.
The implication of Reference numeral in figure:
1-patrix, 2-counterdie, 3-circuit board to be produced, 4-gathering sill, 5-pilot hole, 6-alignment pin, 7-drift.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Generally process by the mode of scalpel hand engraving hollow out under thin framework template for existing production, circuit board exists that accurate to dimension difference, border are coarse, burr serious phenomenon, have a strong impact on the phenomenons such as electrical quantity index such as product S parameter and the flatness of standing wave in band, a kind of member slot for small size Rogers plate that the utility model relates to, for assigning circuit board to be produced, as Fig. 1, comprise the upper die and lower die cooperatively interacted.Upper die and lower die are provided with the identical dowel hole in position, gathering sill and charging conduit.The upper surface of counterdie is provided with die cavity, and die cavity adopts precision grinder processing, and the size of die cavity and circuit board to be produced matches.The drift be also furnished with the alignment pin matched with dowel hole when assembling and matched with die cavity.
Upper die and lower die are laterally divided into two by same die body blank and make.The registration tolerance of upper die and lower die is less than 0.001mm.The gap of drift and gathering sill is 0.005mm.
Circuit board to be produced adopts Rogers's plate.
As Fig. 2, concrete making comprises the steps,
1) Milling Process goes out one block of die body blank, adopts precision grinder grinding to guarantee six perpendicular positioning benchmark here.
2) use electric discharge machine location, pierce spark cutting fabrication hole at a slow speed.
3) on die body blank, spark cutting is at a slow speed used to process dowel hole, gathering sill and charging conduit; Distribution and the circuit board to be produced of dowel hole, gathering sill and charging conduit match.
4) adopt spark cutting to be at a slow speed laterally divided into two in the middle part of die body blank, make upper die and lower die; The registration tolerance of upper die and lower die is less than 0.001mm, to reduce error as far as possible, improves product percent of pass.
5) precision grinder die sinking is adopted at counterdie upper surface; Die cavity and circuit board molded dimension to be produced match.
6) die body is formed by being inserted in locating hole corresponding to upper die and lower die with the alignment pin that dowel hole matches.
7) processing drift is ground according to gathering sill size; The gap of drift and gathering sill is 0.005mm, ensures that drift mates gathering sill completely time to ensure follow-up punching press.
8) described circuit board to be produced is placed in the upper surface die cavity of counterdie, pressure drift carries out stamping-out.
Circuit board to be produced in the utility model adopts Rogers's plate, goes for undersized Rogers's plate.Can effectively accurately be processed undersized Rogers's panel element groove by this method, avoid processing parts in prior art be easily out of shape and form the drawback of burr simultaneously, thus greatly increase production efficiency and product percent of pass, thus production cost is reduced.Product structure of the present utility model is simple, design ingenious, be convenient to make small size Rogers plate, overcome because small size Rogers plate rigid deficiency causes clamping and the difficult problem making difficulty, cost of manufacture is low, dimensional accuracy is high, meets the user demand of research and production.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
