A kind of auxiliary keel forming process and the production line equipment used

Abstract

The invention discloses a forming process of a rider keel and adopted production line equipment, and relates to the field of gypsum board production. Strip steel is formed by being sequentially subjected to 14 passes through corresponding forming devices. The production line equipment comprises the forming device for forming two reinforcing ribs at the bottom of the rider keel in one pass, the forming device for forming hook parts of the rider keel in four passes and the forming device for forming side height parts of the rider keel in nine passes, and gradual-changing forming is adopted for a full set of forming rolls. According to the forming process of the rider keel and the adopted production line equipment, the two reinforcing ribs at the bottom, the hook parts and the side height parts of the rider keel are formed in sequence, the forming devices for the 14 passes are installed on a same rack, a same transmission system is adopted, and the lower forming roll drives the upper forming roll to move; the structure is simple, energy is saved, the production efficiency is improved, and the product quality and percent of pass of production are improved; and the height difference of the two lateral sides of the produced rider keel is within + / -0.2 mm, the dimensional deviation of the hook parts is within + / -0.2 mm, the width deviation of the rider keel is within + / -0.5 mm, and errors of included angles between the lateral sides and the bottom side are within + / -1 degree.

Description

technical field [0001] The invention relates to the field of gypsum board production, in particular to an auxiliary keel molding process and production line equipment used. Background technique [0002] The auxiliary frame DC50*19 is a product with a large market volume in the light steel keel, and the regularity and standardization of the section of the DC50*19 auxiliary frame formed by different molding methods vary greatly. At present, the equipment used has 11 forming passes. The forming process is to form the hook first, and finally form the bottom rib. The formed product is poorly formed and the regularity is not high. Contents of the invention [0003] In order to solve the above-mentioned existing technical problems, the present invention provides a secondary keel forming process and the production line equipment used, the changed process flow of the secondary keel production line, the products produced have good forming effect and high regularity, which greatly im...
