| description | The rectangular rib coating die is formed by sequentially sleeving a die core, a die sleeve, a transition sleeve A, a transition sleeve B, a forming inner sleeve, a forming outer sleeve and a pressingsleeve, and all the components are concentrically matched. The forming inner sleeve and the forming outer sleeve are round outside and square inside; holes are formed in the die sleeve. The inner sizes of the forming inner sleeve and the forming outer sleeve are designed in a clearance mode according to the size of the square rib pipe. According to the utility model, the rectangular PP corrugatedpipe is wrapped by the molten HDPE material flow to form the rectangular reinforcing rib belt; and the rectangular reinforcing rib belt and the molten HDPE flat belt are hot-melted together on a heated steel roller die to form the HDPE high-rib winding reinforcing pipe which is high in rigidity, free of cracking and stripping, large in current-carrying capacity, environment-friendly and pollution-free.
