The invention relates to the technical field of earphone equipment, and discloses a head-mounted noise protection headset and a use method thereof, the head-mounted noise protection headset comprises two main bodies, and the tops of the two main bodies are rotatably connected with an adjusting frame. When the auxiliary ring drives the leather sheath to rotate, the leather sheath part in contact with the skin of a user is twisted and wrinkled by the rotation of the leather sheath, and the leather sheath can wrap and fill the glasses rod between the periphery of the glasses rod and the skin of the user through the twisting of the leather sheath and the formation of the surface wrinkles; therefore, it can be ensured that the leather sheath and the internal sound insulation sponge are tightly attached to the skin of a patient, the tightness of sealing gap attachment between the leather sheath and the skin of a user is reduced, meanwhile, the isolation effect of the main body for isolating external sound through the leather sheath and the internal sound insulation sponge can be improved, and the isolation efficiency of the headset for the external sound is improved.

The invention discloses a method and a system for detecting surface wrinkling defects of a battery diaphragm, and relates to the technical field of machine vision detection. The method comprises the following steps: acquiring an original image of the surface of a diaphragm to be detected, and performing convolution operation on the original image by using a le kernel and an el kernel of a Laws texture filter to extract first texture feature data and second texture feature data; and fusing the two groups of feature data based on a preset weight strategy to generate an enhanced comprehensive texture response image, and performing threshold segmentation on the comprehensive texture response image to obtain a binary image. And geometric morphology feature parameters of the connected regions in the binarized image are calculated, and wrinkling defects are screened and judged based on preset morphology conditions. The invention aims to solve the problems of false detection and missing detection caused by low contrast ratio of diaphragm wrinkling defects and proneness to texture interference in the prior art, and the accuracy and robustness of detection are improved.

The utility model discloses a kind of knitted fabric steam setting devices, including rack and symmetrically installed on rack for conveying fabric conveying belt, rack is fixedly connected with mounting bracket, and mounting bracket and conveying belt form steam cavity between, further including symmetrically installed on mounting bracket's stand, symmetrically and rotationally set up guide for transmission fabric on stand.The utility model can complete pre-heating softening in the process of fabric conveying by setting preheating plate inside conveying belt, effectively eliminate knitted fabric weaving residual internal stress;While matching swing-adjustable first roller and slidable second roller, using gear and meshing tooth meshing transmission and first hydraulic rod tension control structure, can adapt to different width different knitted fabric of gram weight, whole process keeps fabric conveying tension balanced, effectively prevent fabric walking deviation, local relaxation, excessive stretching and surface wrinkle deformation, greatly improve fabric conveying stability and processing adaptation range.

The invention relates to the field of aircraft composite material manufacturing, and discloses an auxiliary tool and method for preventing the surface of a honeycomb core interlayer composite material product from wrinkling, in the composite material skin (layering structure) laying process, skin extends to the position of a hook pulling part, a hook tip part pierces the layering structure, a preformed structure is formed, and the surface of the composite material product is subjected to surface wrinkling; the method can effectively stabilize the upper surface paving layer structure of the honeycomb core material, avoid slippage between the paving layer structure and the honeycomb core material in the curing process, and avoid wrinkles of the upper paving layer structure in the curing process, so that the quality and the manufacturing efficiency of the honeycomb core composite material skin are effectively improved.

The invention relates to high-chromium and high-molybdenum ferritic stainless steel, in particular to a method for improving the formability of the high-chromium and high-molybdenum ferritic stainless steel. The novel method for preparing the high-chromium and high-molybdenum ferritic stainless steel is provided for solving the problems that the surface wrinkling defect exists in the forming process, and the surface roughness is increased in the existing preparation method for preparing the high-chromium and high-molybdenum stainless steel. The method sequentially comprises the following steps of smelting, casting, forging, hot rolling and rough rolling, hot rolling, cooling and finish rolling, curling, uncoiling, solution annealing, acid pickling, cold rolling and recrystallization annealing. The problems of alternate distribution of coarse / fine grains and alternate distribution of alpha, eta and gamma fiber textures in a solid solution structure and a cold rolling annealing structure are solved, recrystallized grains which are small in grain size and are uniformly distributed, and the gamma fiber textures are strong and are uniformly distributed are formed, and the formability of the material is improved.
