Description
Technical field
The utility model relates to a kind of fusion pressure mould, specifically a kind of square fiber products blank fusion pressure mould.
Background technology
Fiber products is by forming through fusion pressure, drawing or torsion, cold working by certain regularly arranged composite filament.Wherein fusion pressure is the critical process that blank is made, and the shape of blank determines quantity and the complexity in the course of processing and the workload size of material therefor.
The optical fiber welding compression mould of traditional structure is mainly used to the pressed section and is shaped as hexagonal blank for optical fibre, and its finished product cross-sectional shape overwhelming majority is circular.Be 90.65% by the long-pending utilization ratio of calculating blank of rounded section.Although this Mold Making is simple, operation is also convenient, and being used for making cross-sectional shape is that square finished product only has 57.75% by the long-pending utilization ratio of calculating blank in square-section, and material use efficiency is on the low side, and before compacting, each operation workload is efficient on the low side.So the fusion pressure mould that need to re-design square fiber products blank is completed the manufacturing of square product blank.
Summary of the invention
The purpose of this utility model provides a kind of blank fusion pressure mould that cross-sectional shape is square fiber products of making.
For achieving the above object, the technical solution adopted in the utility model is:
a kind of square fiber products blank fusion pressure mould, comprise core, press table, side guide, press strip, top board, gland and bed die, the core middle part has groove wide at the top and narrow at the bottom, the bottom surface of groove is horizontal plane, the two side is the inclined-plane, press table is placed on groove floor, the inboard of side guide is vertical surface, the outside is one section inclined-plane, the angle of chamfer of side guide and core side wall angle are complementary angles, two side guides are housed in core, the inclined-plane of two side guides respectively with core both sides sidewall contact, in the space that side guide and press table form, four equally distributed identical press strips of centrosymmetry are housed, press strip is that the cross section is the cylinder of right-angle triangle, the inclined-plane of four press strips inwardly forms a square cavity, the right angle face contacts with side guide or press table respectively, top board is placed on the right angle face of two press strips in top, gland is placed in the top board top, the bed die middle part has groove, core is placed in the groove of bed die.
Be placed on press table repeatedly drawing the orderly approximate square silk integral body of arrangement, place successively two press strips, two side guides, top board and gland in the appropriate position of press table, above-mentioned integral body is placed into the center of bed die with handle, use the sprue push-tight in both sides, again lift bed die with handle and be placed on base plate and be close to preset pieces.Then the mould of assembling being completed is put into the fusion pressure burner hearth, completes the fusion pressure of blank by the vacuum tightness, temperature, the pressure that are fit to.At first gland is suppressed h 1 distance downwards with top board in pressing process, and blank is longitudinally shunk; Simultaneously downwards compacting top board and side guide again make blank longitudinally, laterally all shrink; Blank cross section after compacting becomes square substantially.
It is square fiber products that mould described in the utility model can be used for making the cross section, compares with traditional hexagon blank compacting tool set, has improved the rate of utilization of raw material, has reduced the process redundancy with silk amount and postorder operation, has shortened Production Time and cost of manufacture.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
as Fig. 1, shown in 2, a kind of square fiber products blank fusion pressure mould described in the utility model, comprise core 1, press table 2, side guide 3, press strip 4, top board 5, gland 6 and bed die 10, core 1 middle part has groove wide at the top and narrow at the bottom, the bottom surface of groove is horizontal plane, the two side is the inclined-plane, press table 2 is placed on groove floor, the inboard of side guide 3 is vertical surface, the outside is one section inclined-plane, the angle of chamfer of side guide 3 and core 1 side wall angle are complementary angles, two side guides 3 are housed in core 1, the inclined-plane of two side guides 3 respectively with core 1 both sides sidewall contact, in the space that side guide 3 and press table 2 forms, four equally distributed identical press strips 4 of centrosymmetry are housed, press strip 4 is that the cross section is the cylinder of right-angle triangle, the inclined-plane of four press strips 4 inwardly forms a square cavity, the right angle face contacts with side guide 3 or press table 2 respectively, top board 5 is placed on the right angle face of two press strips in top, gland 6 is placed in top board 5 tops, bed die 10 middle parts have groove, core 1 is placed in the groove of bed die 10.For the ease of assembling and mobile, be fixed with handle 7 on core 1 outer wall.Core 1 bottom center is provided with projection, and press table 2 bottoms have the groove that coordinates with this projection, plays location and fixing effect.Bed die 10 bottom surfaces are provided with tongue, and core 1 bottom is provided with the detent that tongue coordinates.Between the contact both sides face of bed die 10 and core 1, sprue 11 is housed, sprue 11 is used for contacting of push-tight core 1 and bed die 10.Bed die 10 is positioned on base plate 9, and base plate 9 one ends are provided with preset pieces 8, and the top of preset pieces 8 is higher than the bottom of core 1 end face.
During use, at first press table 2 is located by groove and the core 1 of its bottom the center that is placed on core 1; To repeatedly draw the orderly approximate square silk integral body of arrangement is placed on press table 2 again; Two press strips 4 are placed in the appropriate position of press table 2 simultaneously, again at press strip 4 both sides setting side pressing plates 3, the height that should note two side guides 3 this moment is consistent, otherwise the stressed asymmetric phenomenon of whole blank flat face can occur in the fusion pressure process, directly affects the blank internal soundness; Again two other press strip 4 be placed on the top of silk and cover top board 5 in the central position.Whole lift in bed die 10 and be placed on the center of bed die 10 by bed die 10 tongues and core 1 location assurance with handle 7 above-mentioned, should integral body in the downward push-tight of its both sides use sprue 11; Again lifting bed die with handle places it on base plate 9 and is close to preset pieces 8.
The mould that assembling is completed is put into the fusion pressure burner hearth, complete the fusion pressure of blank by the vacuum tightness, temperature, the pressure that are fit to.At first gland 6 is suppressed h 1 distance downwards with top board in pressing process, and blank is longitudinally shunk.Suppress simultaneously top board 5 and side guide 3 downwards, this moment, blank longitudinally continued to shrink again, and side guide 3 promotes the inside transverse contraction of lateral mass when moving downward, and the transverse contraction distance is relevant with the angle θ of downward compacting distance and side guide 3.Determine the angle θ of side guide 3 during design, simulation blank shrinkage is calculated h1 numerical value, determines the concrete structure size of side guide 3, top board 5.The numerical value that the thickness of adjusting top board 5 by pressure testing is namely revised h1 makes the blank cross section after compacting substantially become square.
Determined that as can be known the size of square fiber products, string diameter all can be by the scope of applications of calculative determination die size and mould as long as to sum up state example.Make the blank of square fiber products, overcome the disadvantage of traditional mould, improve the rate of utilization of blank.
