Ultra-high squareness mpo multifilament drawing auxiliary device

Abstract

The invention provides an MPO multifilament wire drawing auxiliary device with ultra-high squareness. The MPO multifilament wire drawing auxiliary device is arranged on the end face of the wire drawing furnace and includes an outer clamp; the inner clamp is smaller than the size of the outer clamp, and the outer clamp and the inner clamp are mutually For diagonal installation, 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 sliders are arranged in the square enclosure, and the plurality of sliders are adjacent to each other to form a centrally located The square hole in the position; each side of the outer clip and the inner clip is provided with a through L-shaped groove and a pushing mechanism arranged in the L-shaped groove, and the pushing mechanism can be locked and released in the L-shaped groove. Switching, in which in the released state, the push rod is acted by the clamping spring, in the vertical direction of the side of the slider, located in one side of the chute, keeps in contact with the corresponding slider and pressed, and in the locked state, push The tightening rod is operated to overcome the elastic force of the clamping spring and is clamped with the slider on the other side of the L-shaped groove to ensure the overall squareness.

Description

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

Problems solved by technology

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 rod has a relatively stable appearance while ensuring that the multifilament rod is not damaged is the difficulty in drawing ultra-high squareness MPO at present.
