The invention relates to a large-dimension aramid paper honeycomb shaping correcting rack trolley which consists of a shaping correcting rack car main body, a W-direction correcting traction device, an L-direction correcting pressing device and the like. The shaping correcting rack trolley is mainly applied to correcting repair after the dimension shrinkage and deformation of a large-dimension aramid paper honeycomb (W direction*L direction*T direction greater than or equal to 2620 mm*1350 mm*900 mm) exceed tolerance; W-direction maximal correcting stretching stroke is 400 mm; L-direction maximal correcting pressing stroke is 300 mm; one-way traction drawing force can be 2 tons; and corrected honeycomb blocks are stable in dimension, are regular in appearance and are uniform in holes. The shaping correcting rack trolley has the characteristics of being simple in structure, convenient to operate, high in correcting efficiency and the like, and is matched with an oven for use, so that the correcting repair requirements after the large-dimension aramid paper honeycomb has dimension shrinkage and deformation can be met, and the product qualification rate is effectively increased.
Description
technical field [0001] The invention relates to a large-size aramid paper honeycomb shaping correction frame, which is used in the production process of large-size aramid paper honeycombs in the field of aviation composite materials. Background technique [0002] Large-sized aramid paper honeycomb (W direction × L direction × T direction ≥ 2620mm × 1350mm × 900mm) will have different degrees of shrinkage after the setting and dipping process. If the size shrinkage and deformation exceed the design tolerance, it will be It will directly affect the appearance, hole shape and process size of honeycomb products, resulting in unqualified products, waste of raw materials and economic losses. At present, the large-size aramid paper honeycomb preparation technology has not been developed for a long time, and there is still no supporting equipment to solve this problem. Therefore, it is necessary to invent a calibration device to repair and solve the problems that may occur in the la...
