Large-size honeycomb stretching connecting piece

Abstract

The invention relates to the technical field of honeycomb production and particularly relates to a large-size honeycomb stretching connecting piece. The large-size honeycomb stretching connecting piece comprises a connecting surface and a plurality of pull rings, wherein two pull ring feet of each pull ring are sutured with the connecting surface, and the connecting surface and the pull rings are made of aramid paper. When the large-size honeycomb stretching connecting piece provided by the invention is used, by connecting the connecting surface with a honeycomb body, steel needles are inserted into the pull rings, and the top ends of the steel needles are connected on a stretching machine, so that the requirements of stretching forming can be met, the requirements of various process parameters of follow-up process steps can be met, and the production efficiency is greatly improved; the product quality can be ensured, and the material problem for manufacturing the large-size honeycomb stretching connecting piece is further solved. The large-size honeycomb stretching connecting piece provided by the invention has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of honeycomb production, in particular to a large-size honeycomb tensile connector. Background technique [0002] The stretching process of aramid honeycomb is one of the key processes of honeycomb forming. After the stacking is completed, the stretching machine is used to stretch the stack into a honeycomb shape, and the stretching connector is to connect the stack and the stretching machine, and The critical link that makes the stretch into shape. For small-sized honeycomb (thickness less than 200mm) stacked plates, because of the small tensile force, it can be directly drawn with Φ5mm steel needles, and the tensile force of large-sized (914mm thick) is as large as about 10 tons. , must be drawn with Φ18-22mm steel rods on a specially designed and developed stretching machine. The honeycomb with the largest cells can only be inserted at most about 10 mm. To draw a large-sized honeycomb, it is necessary t...

AI Technical Summary

Problems solved by technology

The honeycomb with the largest cells can only be inserted at most about 10 mm. To draw a large-sized honeycomb, it is necessary to use a special laminated stretching "connector". Most of the foreign large-sized honeycombs are drawn with high-strength special materials. There is no such thing in China. Purchasing channels, the price of special import is quite expensive, and it is not a long-term solution. Completing the material selection, size design and process control of tensile connectors is a necessary link to realize large-scale honeycomb production
