Processing protection device and processing equipment for amorphous strips of amorphous three-dimensional rolled iron core transformer

Abstract

The invention discloses processing protection device and processing equipment for amorphous strips of an amorphous three-dimensional roll iron core transformer, and relates to the technical field of advanced machining of amorphous alloy strips. The device comprises a weight detection device, a transmission mechanism, an emergency emptying protection mechanism and a strip transmission detection feedback assembly. The device and equipment of the invention have the advantages that the amorphous strips discharged by a discharging device can be freely placed in advance in an unconstrained mode through the protection device, and are prevented from over-limit stretching, the emergency discharging protection mechanism can change the speed of a strip discharging mechanism when finding that the weight information transmitted by a weighing sensor is abnormal, and after the transmission mechanism receives a strip transmission tensioning overload feedback signal of the strip transmission detectionfeedback assembly, the strip speed adjusting function can be achieved according to the feedback signal transmission mechanism; and the situation that the strip is snapped or folded due to the fact that a receiving unit and the discharging unit cannot be rapidly coordinated and matched due to the conveying speed is avoided.

Description

technical field [0001] The invention relates to the technical field of advanced processing of amorphous alloy strips, in particular to a strip protection device and processing equipment for processing amorphous alloy strips. Background technique [0002] Amorphous alloy, also known as metallic glass, is formed by processing molten steel into an ultra-thin strip with a thickness of only tens of microns through rapid cooling technology. The obtained solid alloy is different from the crystal structure in which atoms are regularly arranged in cold-rolled steel materials. Because the atoms of this alloy are in an irregular amorphous structure, it has excellent physical properties such as high efficiency, low loss, and high magnetic permeability, which promotes the development of electronic components in the direction of high frequency, high efficiency, energy saving, and miniaturization. Partially replace traditional silicon steel, permalloy and other materials. Especially in po...

Problems solved by technology

[0003] In the production process of the iron core in the amorphous three-dimensional wound core transformer, the winding amorphous strip is required to be complete without tearing, folding and breaking, so as to ensure that the three-dimensional winding of the amorphous strip is tight, the iron core has no seams, and the air gap The loss is small. Therefore, the processing quality of the transmission strip must be controlled during the cutting and cutting process of the amorphous alloy strip. At present, the processing equipment for the amorphous alloy strip has different transmission speeds during the processing process. The problem of matching leads to frequent breakage, tearing and surface scratches during strip processing, resulting in gaps and loose fit defects between strips after cutting and winding, which seriously affects the subsequent amorphous alloy strips. The production efficiency of material three-dimensional wound transformer core and the working performance of transformer
