A kind of manufacturing method of FRP electric meter box

Abstract

The invention relates to a method for processing and manufacturing a glass fiber reinforced plastic meter box, which uses a sheet forming device, the sheet forming device includes a bottom plate, a shaping device, a connecting frame and a pressing device, a shaping device is installed on the upper end of the bottom plate, and the upper end of the shaping device is arranged There is a pressing device, and the pressing device is connected to the bottom plate through the connecting frame; the specific methods of processing the FRP electric meter box with the above-mentioned sheet forming equipment are as follows: sheet forming, film cutting, curing treatment, molding treatment and combined assembly. The sheet forming equipment used in the present invention, through the cooperation of the shaping device and the pressing device, jointly completes the forming work of a single sheet, and only needs to cut off the excess film after forming, without cutting the sheet Processing, the difficulty of processing is significantly reduced, and the pressing device can stir the resin paste and glass fiber during the molding process, thereby improving the uniformity of distribution of the two.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic electric meter boxes, in particular to a processing and manufacturing method of glass fiber reinforced plastic electric meter boxes. Background technique [0002] FRP generally refers to reinforced plastics with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, and glass fiber or its products as reinforcement materials, called glass fiber reinforced plastic, or FRP, which is different from tempered glass. [0003] FRP is light and hard, non-conductive, stable in performance, high in mechanical strength, less recycled, and resistant to corrosion. It is often used as a material for electric meter boxes. The process of making a FRP meter box includes the step of making a sheet molding compound (hereinafter referred to as a sheet), and there are some problems in this process: [0004] (1) In order to ensure that the glass fibers can be evenly ...

AI Technical Summary

Problems solved by technology

[0004] (1) In order to ensure that the glass fibers can be evenly distributed in the resin paste, after the glass fibers are deposited on the resin paste coated on the lower carrier film and covered with the upper carrier film, they must pass through a plurality of roller arrays arranged in random order, so that The upper and lower supporting film, resin paste and glass fiber can be tightly pressed, the whole production line is long, the input cost is high, and the processing efficiency is low;

[0005] (1) When the resin paste and glass fiber are mixed evenly, a continuous sheet is produced. Before the sheet is put into use, the sheet needs to be cut into an appropriate size according to the actual needs. The strength of the sheet is high, so cutting Cutting is difficult, and the cutting work cannot be completed efficiently. In addition, during the cutting process, the friction between the tool and the FRP sheet is large, resulting in high heat and large loss of the tool.
