| titleOfInvention | Winding processing method of large-caliber FRPP (reinforced polypropylene) reinforced pipe |
| abstract | The invention relates to the field of pipe processing, in particular to a winding processing method of a large-caliber FRPP (reinforced polypropylene) reinforced pipe, which comprises the following steps: step 1: preparing a pipe winding processing system, which comprises a rack, an extruder, a winding pipe, a cooling chamber and an assembly table, wherein an extrusion opening of the extruder is U-shaped, a W-shaped pressing box is fixed on the rack, and a perforated strip is arranged in the pressing box in a sliding manner; step 2: the side walls of adjacent coiled materials on the winding pipe are contacted and bonded to form a semi-finished product; and step 3: the pressing box presses the bonding position of the side wall of the coiled material, and the perforating strip is moved to pass through the bonding position of the side wall of the coiled material in a reciprocating mode, so that a trapezoidal hole is formed in the bonding position of the side wall of the coiled material; and 4, step 4: moving the semi-finished product to a cooling chamber in the process of rotating along with the winding pipe, and cooling the semi-finished product to obtain a finished product; and 5: and preparing the trapezoidal block, and assembling the trapezoidal block into the trapezoidal hole after the finished product is moved to the assembling table. When the technical scheme is adopted, the strength of the pipe is favorably improved. |
