Problems solved by technology

[0004] However, in the existing technology, in the process of processing FRPP pipes, the extruded coils are inverted T-shaped, and the bonding position is relatively thin during the winding molding process, which cannot achieve firm bonding, resulting in the laying of FRPP large-diameter pipes. easy to break during use

Embodiment 1

[0032] A winding processing method for large-diameter FRPP reinforced pipes, comprising the following steps:

[0033] Step 1: Prepare as figure 1 A pipe winding processing system shown includes a frame, an extruder 1, a servo motor 2, a winding pipe 3, a cooling chamber 4, a cutting table 5 and an assembly table 6, and the extruder 1 is a twin-screw extruder 1 , and its extrusion port is in the shape of "U". The servo motor 2 is fixed on the frame by bolts, the model of the servo motor 2 is MR-J2S-700A, the left end of the winding pipe 3 is rotated and arranged on the frame, and the winding pipe 3 is connected with the output shaft of the servo motor 2 by a belt. Such as image 3 As shown, the frame is fixed with a "W"-shaped pressing box 7 by bolts, the side wall of the pressing box 7 is provided with a channel 8, and an opening strip 9 is slidably arranged in the channel 8; A cylinder 10 is fixedly installed by bolts in the box 7, and the perforated bar 9 is welded with t...

Embodiment 2

[0039] On the basis of embodiment one, from Figure 7 Viewed from the left side, the bottom of the press box 7 is arc-shaped, and both sides of the press box 7 bottom have material leakage ports. at the same time as image 3 As shown, the press box 7 is connected with a cover plate 13 through a hinge.

[0040] In addition, different from Embodiment 1, two automatic welding machines are arranged between the pressing box 7 and the cooling chamber 4, one is fixed on the frame outside the winding pipe 3 by bolts, and the other is installed on the The inner side of the winding pipe 3, specifically, the inner side of the winding pipe 3 is installed as figure 1 Shown support plate 16, the left end of support plate is welded with frame, and another automatic welding machine is fixedly installed on the support plate 16 by bolt, and the welding torch of this automatic welding machine is positioned at the right-hand end of winding pipe 3. The welding torches of the two automatic weldi...

Abstract

The invention relates to the field of pipe processing, in particular to a winding processing method of a large-diameter FRPP finned pipe. The winding processing method of the large-diameter FRPP finned pipe comprises the following steps that the step 1, a pipe winding processing system is prepared and comprises a machine frame, an extruding machine, a winding pipe, a cooling chamber and an assembly platform, an extrusion opening of the extruding machine is in a U shape, a W-shaped press fit box is fixed to the machine frame, and a hole forming strip is arranged in the press fit box in a sliding mode; the step 2, the side walls of adjacent coiled materials on the winding pipe make contact with each other and adhere to each other, and a semi-finished product is formed; the step 3, the pressfit box conducts press fit operation on the adhesion positions of the side walls of the coiled materials, the hole forming strip is moved in a reciprocating mode to pass through the adhesion positionsof the side walls of the coiled materials, and therefore trapezoidal holes are formed in the adhesion positions of the side walls of the coiled materials; the step 4, the semi-finished product is moved to the cooling chamber in the process that the semi-finished product rotates along with the winding pipe, the semi-finished product is cooled, and then a finished product is obtained; and the step5, trapezoidal blocks are prepared, and the trapezoidal blocks are assembled in the trapezoidal holes after the finished product is moved to the assembly platform. When the technical scheme is adopted, the strength of the pipe is improved advantageously.

Description

technical field [0001] The invention relates to the field of pipe material processing, in particular to a winding processing method for large-diameter FRPP reinforced pipes. Background technique [0002] FRPP pipes are resistant to corrosion, high temperature, and high pressure, and have excellent impact resistance and tensile strength. They are suitable for the transportation of corrosive liquids (such as acid and alkali) and municipal water supply and drainage systems. FRPP pipes are generally buried in soil or concrete. , Widely used in drainage and sewage engineering. [0003] At present, the commonly used pipe extrusion processing can only produce FRPP drainage pipes with a maximum diameter of 1200mm. If large-diameter FRPP pipes are to be produced, the investment in equipment and molds is large, which limits the application of FRPP pipes. The common production method of FRPP large-diameter (greater than 1200mm) pipe is to wind the extruded strip on the mold, so that t...
