Rolling machine for RTP composite pipes and winding pipes

Abstract

The invention discloses a rolling machine for RTP composite pipes and winding pipes. The rolling machine for the RTP composite pipes and winding pipes comprises a machine frame, a core shaft is arranged in the machine frame, and a driving device is arranged at the rear end of the core shaft. A rolling roller is arranged in the machine frame, the rolling roller is arranged above the core shaft, andthe rolling roller is rotatably mounted on a mounting frame. A buffer device is conneted to the top end of the mounting frame, and a lifting device is arranged at the top end of the buffer device. Aheating device is arranged in the machine frame, the heating device is arranged on one side of the core shaft, an extrusion head is connected to the front end of the core shaft, the extrusion head isfixed to the machine frame, and a cooling device is arranged at the front of the extrusion head. The rolling machine for the RTP composite pipes and winding pipes solves the problem that the extrusionforce between the rolling roller and the core shaft is inconvenient to adjust in an existing structure, the cooling device is arranged at the extrusion head to perform cyclic utilization on hot air in the machine frame, the use ratio of energy sources is improved, energy conservation and environmental protection are better achieved, the product quality is ensured, and the production efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of RTP composite pipe processing equipment, in particular to a winding pipe rolling machine for RTP composite pipe. Background technique [0002] RTP pipe is the abbreviation of fiber reinforced thermoplastic composite pipe, which is composed of inner pipe, fiber reinforced layer and outer pipe. Because of its corrosion resistance, high pressure resistance, light weight, high flexibility, and coilability, it is widely used in land, petroleum, sewage, chemical, gas transmission and other fields, and it has been applied to submarine oil pipelines in recent years. The preparation of the composite pipe is generally through the winding molding process. The winding molding process is to wind the continuous fiber (or cloth tape, prepreg yarn) soaked in the resin glue solution on the mandrel according to certain rules, and then solidify and demould to obtain Products, the winding tube forming machine is the main eq...

AI Technical Summary

Problems solved by technology

However, during the process of winding the sheet on the mandrel, air is easily mixed between the sheets, which affects the quality of the pipe. Therefore, it is necessary to install a rolling device to squeeze out the air between the sheets to improve the product qualification rate.

However, the current rolling device has the problem of inconvenient adjustment. During the forming process, the thickness of the pipe will gradually increase. If the distance between the rolling roller and the mandrel is too large, the rolling pressure will be insufficient and it will be difficult to discharge the air. effect; if the distance between the rolling roller and the mandrel is too small, the thickened pipe will be difficult to enter due to the excessive extrusion force, which will affect the normal pipe forming
