Description

The microchannel plate manufacturing is with arranging the silk mould

Technical field

The utility model relates to a kind of microchannel plate manufacturing with arranging the silk mould, is used for row's wire process of microchannel plate production process.

Background technology

Microchannel plate is an a kind of novel electronic multiplication body, has that volume is little, in light weight, working voltage is low, noise is little, the electron gain advantages of higher.At present, microchannel plate is mainly made with " real core method " technology of repeatedly pulling special glass rod pipe assembly.

Because the passage aperture of microchannel plate is very little, generally below 12 μ m, for this reason, the glass bar pipe must repeatedly stretch.The tiny filamentary external diameter of at every turn pulling out is generally below 0.3-0.5mm, then the thin glass fiber of thousands of external diameter 0.3-0.5mm is put into row's silk mould, precision is arranged in the Fiber glass rod of regular hexagon, through stretching for the second time, becomes the multiple fibre of regular hexagon again; Then multiple fibre is cut into certain length, enters in the special pressure screen mould, depress to the base substrate of regular hexagon, make microchannel plate through series of processes such as section, grinding, polishing, sour molten coring, reduction, electrode evaporations again at HTHP.

Tiny ultimate fibre to be arranged as a regular hexagon cluster, be the work of extremely meticulous difficulty, for example, the microchannel plate of aperture 5 μ m, to line up the regular hexagon fibre bundle with the up to ten thousand monofilament of external diameter 0.33mm length 500mm, and defectives such as the silk of lacking, room, dislocation, fracture of wire wherein can not be arranged, not have row's silk mould and corresponding method of operation reasonable in design, be difficult to finish, can this be one of the key technology that make the small-bore microchannel plate.

Row's silk method of prior art and mould be referring to Fig. 1～Fig. 3, and this method requires Mould Machining precision height, operator's technology very skilled, but can only arrange the above fiber of diameter 0.5mm, and the fiber below the diameter 0.5mm then is difficult to arrange.

Can find out that from Fig. 1 row's silk mould comprises patrix 1 ' and counterdie 2 ', has the screw 4 ' of location and fastening usefulness on patrix 1 ' and the counterdie 2 ', and screw is installed in the screw 4 '.Patrix 1 ' and counterdie 2 ' are formed one positive six prismatic cavity 3 ' as the working region, and glass fibre 5 ' just enters wherein, as Fig. 2 and Fig. 3.The characteristics of this mould are simple in structure, make easily, but have serious deficiency: the fiber of the first half can only insert by section, this brings very big difficulty to practical operation, thin and long glass fibre 5 ' can not effectively be arranged in this mould, can not adapt to the production requirement of high-performance microchannel plate.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and a kind of reasonable in design, the effective microchannel plate manufacturing of row's silk row's silk mould are provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of microchannel plate manufacturing is characterized in that: comprise backform, left mould, right mould and bed die with row's silk mould; Left side mould and right mould symmetry are inserted on the bed die, and backform is inserted on left mould and the right mould; Backform, left mould, right mould and bed die surround one positive six prismatic cavity.

The utility model has trapezoidal left bed die guide groove and trapezoidal right bed die guide groove on described bed die; Be fixed with trapezoidal left mould guide block on described left mould, left mould guide block is inserted in the left bed die guide groove; Be fixed with trapezoidal right mould guide block on described right mould, right mould guide block is inserted in the right bed die guide groove.

The utility model has trapezoidal left mould guide groove on described left mould, have trapezoidal right mould guide groove on described right mould; Be fixed with trapezoidal left backform guide block and trapezoidal right backform guide block on described backform, left backform guide block is inserted in the left mould guide groove, and right backform guide block is inserted in the right mould guide groove.

The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, the fibre bundle quality that ejects is guaranteed, can pull out high-quality multiple fibre, makes the microchannel plate of high resolution.3, row's silk is simple to operate, and row's silk process is controlled.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment:

Referring to Fig. 4, the utility model embodiment comprises backform 1, left mould 2, right mould 3 and bed die 4.Have trapezoidal left bed die guide groove 41 and trapezoidal right bed die guide groove 42 on the bed die 4, left bed die guide groove 41 and right bed die guide groove 42 are symmetrical arranged.Left side mould 2 is fixed with trapezoidal left mould guide block 21 in the bottom, have trapezoidal left mould guide groove 22 at the top, and left mould guide block 21 and left mould 2 are as a whole, and left mould guide block 21 is inserted in the left bed die guide groove 41.Right mould 3 is fixed with trapezoidal right mould guide block 31 in the bottom, have trapezoidal right mould guide groove 32 at the top, and right mould guide block 31 and right mould 3 are as a whole, and right mould guide block 31 is inserted in the right bed die guide groove 42.Be fixed with trapezoidal left backform guide block 11 and trapezoidal right backform guide block 12 on the backform 1, left backform guide block 11 and right backform guide block 12 and backform 1 are an integral body, and left backform guide block 11 is inserted in the left mould guide groove 22, and right backform guide block 12 is inserted in the right mould guide groove 32.

Backform 1, left mould 2, right mould 3 and bed die 4 surround the cavity 5 of a positive hexagon as the working region.A left side mould 2 and right mould 3 are that line of symmetry becomes left-right symmetric with the center line of cavity 5.Cavity 5 wherein 3 inwalls is positioned on the bed die 4, and remaining 3 one of inwalls are positioned on the backform 1, and one is positioned on the left mould 2, and one is positioned on the right mould 3.
