MPO multifilament drawing auxiliary device with ultrahigh squareness

Abstract

The invention provides an MPO multifilament drawing auxiliary device with ultrahigh squareness. The device is arranged on the end surface of a drawing furnace and comprises: an outer clamp; an inner clamp, wherein the size of the inner clamp is smaller than that of the outer clamp, and the outer clamp and the inner clamp are installed diagonally, so that the outer clamp at least partially clamps the inner clamp, and a square enclosure is formed between the outer clamp and the inner clamp; a plurality of sliding blocks arranged in the square enclosure, wherein every two of the sliding blocks are adjacent to form a square hole located in the center; and through L-shaped grooves arranged on each edge of the outer clamp and the inner clamp and pushing mechanisms arranged in the L-shaped grooves, wherein the pushing mechanism can be switched between a locking state and a releasing state in the L-shaped groove, in the releasing state, a pushing rod is acted by a clamping spring and located in one side of a sliding groove in the direction perpendicular to the side face of the sliding block, contacts with the corresponding sliding block and is pressed, and in the locking state, the pushingrod is operated to overcome the elastic force of the clamping spring, and the pushing rod and the sliding block are clamped on the other side of the L-shaped groove, so that the overall squareness isguaranteed.

Description

technical field [0001] The invention relates to the field of microporous optical element MPO technology, in particular to an ultra-high squareness MPO multifilament drawing auxiliary device. Background technique [0002] Micropore optics (MPO) is a grazing incidence high-energy ray focusing optical element, which can focus photons in x-ray and ultraviolet bands. like figure 1 The microstructure diagram of MPO is shown. MPO is a thin sheet of glass material with a porous structure consisting of millions of square micropores with a micron-scale size. The inner wall surface of the micropores has extremely low roughness. The shape of MPO can be divided into two types: plane and spherical. Among them, the plane MPO can converge the divergent light, and the spherical MPO can converge the parallel light. Among all currently known X-ray optical components, MPO has the smallest volume and mass while ensuring a large field of view and high resolution. [0003] The multifilament dra...

combine figure 2 The drawing process of the MPO multifilament rod shown, that is, the diameter change process, is currently extremely difficult to control the squareness of the MPO multifilament. In a high temperature environment, it is difficult for the drawn multifilament to meet the technical requirements, and the yield rate is low. How to ensure that the drawn multifilament rods have a relatively stable appearance and at the same time ensure that the multifilament rods are not damaged is the current difficulty in drawing ultra-high squareness MPO
