Embodiment Construction

[0027] Figure 1 ~ Figure 4 Shown is the embodiment of a threading mold for the production of a reinforced thermoplastic pipe reinforcing tape of the present invention, as figure 1 As shown, it includes a base body 1 and a threading orifice plate 2, and the base body 1 and the threading orifice plate 2 are detachable mosaic structures. The base body 1 is provided with several fixing holes 11 , two positioning pin holes 12 and two flow channel holes 13 . The perforated plate 2 is made of die steel, alloy material or wear-resistant material treated with surface coating.

[0028] Such as figure 1 As shown, square threading holes 21 are horizontally arranged on the threading hole plate 2 . Such as figure 2 As shown, the four corners of the threading hole 21 are rounded, and the side length L of the threading hole 21 is 0.2-0.6 mm larger than the diameter D of the silk rope / string 3 .

[0029] Such as image 3 with Figure 4 As shown, the middle part of the substrate 1 is p...

Abstract

The invention discloses a threading mold for producing a reinforcing band for strengthening a thermoplastic plastic pipe. The threading mold comprises a base body and a threading hole plate, wherein threading holes are arranged on the threading hole plate side by side. The threading holes are square structures. The threading mold effectively solves the problem that silk ropes / cotton ropes are easily abraded and broken in the manufacturing process of the interlayer reinforcing band, effectively improves the rate of finished reinforcing band products manufactured by the silk ropes / cotton ropes, guarantees stable and continuous production and remarkably improved the production efficiency.

Description

technical field [0001] The invention relates to the technical field of reinforced thermoplastic pipe production, in particular to a mold for arranging and conveying metal wire ropes or fiber wire ropes when preparing reinforced thermoplastic pipe reinforcement bands. Background technique [0002] Reinforced Thermoplastic Pipe (RTP for short) was developed in the early 1990s. It is mainly composed of three-layer structure. The inner and outer layers are made of PE80 or higher materials. Ultraviolet) or black (buried laying), the middle layer is a reinforcing belt made of reinforcing materials such as metal wires or ropes, fiber cords. Compared with ordinary plastic composite pipes, RTP has the characteristics of high pressure resistance, good toughness, easy installation and laying, and low overall cost. meters, is currently the only pressure pipe that can reach this length, thereby greatly reducing the connection joints between pipes, increasing the construction speed by do...
