A kind of anti-corrosion pipe liner compression molding press

Abstract

The invention discloses an anti-corrosion pipeline liner press forming press, which comprises a base, two left and right symmetrical support columns are fixed on the upper end surface of the base, and two vertically symmetrical arc adjustment mechanisms are arranged between the two support columns. A lining forming mechanism for anti-corrosion lining molding is arranged between the arc adjustment mechanisms; the present invention realizes anti-corrosion linings of different sizes through the upper and lower pressing plates that can adjust the arc and the width-limiting columns on the left and right sides that can adjust the spacing. It reduces the number of sets of molds required for the production of linings of different sizes, reduces production costs, and reduces the steps of replacing molds, improving production efficiency. The plastic raw material in the molten state can be molded under the pressure provided by its own gravity, which avoids the problem of poor molding quality of the anti-corrosion lining due to uneven force on the curved mold.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a press for forming anti-corrosion pipeline linings. Background technique [0002] The anti-corrosion lining has the ability to protect metal or other substrates from various media, resists the corrosion of acids, alkalis, inorganic salts and various organic substances, and has good elasticity, wear resistance, impact resistance and metal and other Adhesive properties of the substrate. [0003] The current plastic anti-corrosion lining is formed by a press, and when the ordinary press produces pipe linings of different sizes, it can only be realized by replacing different molds. The increase in the number of molds greatly increases the production cost. The inner lining is made by heating the press to soften the workpiece, and then the inner lining is formed by extrusion through the mold of the press, and the curved mold is likely to cause uneven force during extrusion, which aff...
