Extrusion mold for producing conductive glass steel pipe

Abstract

The invention provides an extrusion mold for producing a conductive glass steel pipe. The extrusion mold is used for extruding shaping the conductive glass steel pipe in the stretching and extrusion molding process. The extrusion mold comprises an inner mold located at one side of a feeding end and an outer mold located at one side of a traction end, the inner mold is provided with an outer surface corresponding to an inner surface of the conductive glass steel pipe, and the inner mold and the outer mold are arranged side by side along the length direction of the conductive glass steel pipe. The inner mold and the outer mold of the extrusion mold are arranged side by side, so that the conductive glass steel pipe does not contact any object on the outer side of the inner mold and the innerside of the outer mold, the longitudinal stress on the conductive glass steel pipe can be greatly reduced, the extrusion stress of the conductive glass steel pipe can be reduced, the rate of finishedproducts can be improved, and the cost can be saved.

Description

technical field [0001] The invention relates to an extrusion die, in particular to an extrusion die which can be used to manufacture conductive glass steel pipes through a pultrusion process. Background technique [0002] In the electrostatic demister for the separation of gas impurities, the anode tube bundle made of conductive glass fiber reinforced plastic has been used more and more. For example, Chinese patent CN 2376335 Y provides a glass fiber reinforced plastic anode tube of an electric demister, and the section of the anode tube is a regular hexagon. The diameter of the inscribed circle of the anode tube with regular hexagonal cross-section can reach about 300mm, the wall thickness of the anode tube is 3-10mm, and the length of the anode tube can reach about 6m. It can be seen that this kind of anode tube is a part with a long length and a thin wall thickness, so its length direction can bear a large tensile force, but the strength in the side wall direction is low...

AI Technical Summary

Problems solved by technology

[0004] Wherein, if the anode tube in CN 2376335 Y adopts figure 1 In the production of the pultrusion machine shown, the part of the anode tube clamped by the traction mechanism 5 is easily broken, so it is necessary to provide an extrusion die 4 that can be used to manufacture conductive glass steel pipes through the pultrusion process to reduce the anode tube. The pultrusion force of the tube improves the yield and saves the cost
