Threading auxiliary device for glass steel tube production and rapid threading method

Abstract

The invention relates to a threading auxiliary device for glass reinforced plastic pipe production and a rapid threading method. The threading auxiliary device comprises a threading device body, wherein the threading device body is provided with a plurality of side surfaces, the side surfaces are sequentially connected to form a closed annular surface, at least two adjacent side surfaces in each side surface are respectively provided with a group of guide tooth groups, each guide tooth group comprises N guide teeth which are sequentially arranged at a certain interval A, the number N of the guide teeth of each guide tooth group 3 is the same, and the intervals A of the guide teeth in each guide tooth group are different; a thread passing groove with the depth of H1 is formed in the tooth head of each guide tooth, and the distance between the groove bottom of each thread passing groove and the side face, connected with the corresponding guide tooth, of the threading device body is H2. When the annular surface of the threader body rotates automatically, rapid threading is achieved, a galling phenomenon generated by glass filaments during manual threading is avoided, the human uncertainty is reduced, and the process quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to a threading auxiliary device and a threading method for the production of glass steel pipes. Background technique [0002] The production process of FRP pipes includes wire threading section, wire guiding section and winding section. The guide wire section adopts the guide wire comb bar 8 (such as Figure 7 , 8 ), the comb teeth on the guide wire bar 8 are cylindrical, the comb tooth diameter is 3mm, and the comb tooth spacing B of the guide wire bar is gradually reduced along the threading direction of the glass fiber line. The three specifications of the guide wire bar For example, they are respectively the guide wire bars with large spacing in the front, the guide wire bars 81 with intermediate spacing in the middle, and the guide wire bars 82 with small spacing in the rear. [0003] The wire guide bar 8 combs each glass fiber thread 7' before winding each glass fiber thread, so that each glass fiber thread is arranged in ...

Problems solved by technology

[0005] The purpose of this invention is to overcome the shortcomings of difficult quality control and low efficiency of manual threading of existing glass steel pipes, and propose a threading auxiliary device for glass steel pipe production. Workers can change different guide teeth according to the comb tooth spacing to achieve fast Threading, to solve the phenomenon of roughening of glass filaments during manual threading, reduce artificial uncertainty, thereby improving process quality and production efficiency
