A kind of forming method of vertical coaming plate of electrolytic cell

Abstract

The invention relates to a method for forming a vertical coaming of an electrolytic cell. The method includes the following steps: (1) part blanking: cutting a plurality of vertical coaming part slats simultaneously on a steel plate by means of intermittent cutting; (2) Scribing: draw the start line and end line of the arc section of the vertical coaming on the steel plate; (3) arc forming: use a small-diameter three-roller plate rolling machine to roll and form, and first roll the vertical coaming side The arc is rolled from the starting line of the arc segment to the end line of the arc segment. During the rolling process, the accuracy of the arc is checked by the arc model, and the arc on the other side is rolled after passing the pass; (4) Cutting: the steel plate A certain length of connection section reserved on the board is cut to form a single part. The forming method of the invention solves the problems of low efficiency, low rounding precision, poor appearance quality and the like of the traditional forming method. The method adopted by the invention can simultaneously process a plurality of parts at one time, and realize batch forming of the vertical shrouds of the electrolytic cell.

Description

technical field [0001] The invention relates to a manufacturing process of a vertical shroud for an electrolytic tank shell, in particular to a forming method for a vertical shroud of an electrolytic tank. Background technique [0002] The vertical coaming plate is a part of the electrolytic cell shell. Its shape is similar to U-shaped, and the two sides of the U-shaped bottom need to be processed into arcs with a certain radius. At present, the usual method of forming vertical panels is to use flame simmering to form after blanking a single part or to make arc molds for cold pressing. This processing method can only process one part at a time, which is inefficient. If multiple parts are processed at the same time, it must be The production of large-scale molds requires high specifications of the press, and large-scale equipment needs to be purchased at a high cost. In addition, the arc shape of the parts processed by this method is not smooth, the forming precision is low, ...
