Vertical pipe production line

Abstract

The invention discloses a vertical pipe production line. The vertical pipe production line is characterized in that: a core shaft support is arranged on a lower portion of a frame, a mold core shaft is erectly fixed on the core shaft support, a propulsion device connected with a first power generator is arranged on a lower portion of the mold core shaft; at least a support frame is fixed on the frame, a circular orbit and a second power generator are arranged on the support frame, the core shaft support is positioned in the center of the circular orbit, a circumferential yarn disk is arrange on the circular orbit and is connected with the second power generator; a circular dipping groove is arranged on the support frame approaching a circumference inside the circular orbit, a axial fiber position frame and a circumferential fiber position frame are distributed on the circular dipping groove; a product synchronization cutting apparatus is fixed on an upper end of the frame, the productsynchronization cutting apparatus is positioned above the mold core shaft. According to the present invention, the vertical pipe production line is adopted, such that circumferential winding of the continuous fibers and axial arrangement of the continuous fibers are combined well so as to improve product quality and processing stability.

Description

technical field [0001] The invention relates to pipeline production equipment, in particular to a vertical pipeline production line for producing thermosetting plastic materials. Background technique [0002] At present, the relatively advanced pipeline production line in use in China is a mechanized extrusion hot-melt composite pipeline production line, the raw material of the middle layer is mainly high-density polyethylene, the metal of the inner and outer layers is aluminum, and the composite method is extrusion and hot-melt. Mainly, this kind of production line can only produce small-diameter (less than 80mm) composite pipes due to the limitation of technology and manufacturing equipment, and this type of composite pipe has low pressure, which is very destructive to the molecular structure of sandwich raw materials during the manufacturing process, and the cost of raw materials is high. , high energy consumption, low output, and large floor area. However, the existing ...

Problems solved by technology

However, this patented technology has at least the following disadvantages: first, because it is a horizontally arranged production line, it needs to occupy a large space, especially when it is necessary to wind multi-layer pipes, its equipment will also be increased accordingly, which will occupy more space. The production site; the second is that under the action of gravity, the pipe mold will be bent and deformed, and the bent and deformed mold will cause uneven stress on the fibers inside the product; at the same time, the resin will flow downward and concentrate in the lower part of the pipe, resulting in uneven thickness of the pipe

When this kind of pipeline is in use, stress concentration will form a weak point and cause the pipeline to rupture
