A kind of manufacturing method of T profile

Abstract

The invention relates to a method for manufacturing a T sectional material. The method includes the following steps that first, a manufacturing tool is obtained; second, a panel marked with the center installation line is laid in a groove of the tool; third, a rotating backer at one side of a fixed platform is closed and further locked with a wedge-shaped locking block; fourth, a matched web is vertically hoisted onto the panel through hoisting equipment, so that the web abuts against the closed rotating backer firmly; fifth, a rotating backer at the other side of the fixed platform is closed and further locked with a wedge-shaped locking block, and then the panel and the web are positioned by means of spot welding; and sixth, the backers at the two sides of the fixed platform are loosened, two welding tractors are arranged at the two sides of the web so that the two sides of the web can be welded at the same time, and the T sectional material can be manufactured after welding is completed. By the adoption of the method for manufacturing the T sectional material, production efficiency is greatly improved, final product quality is guaranteed, and construction safety is improved.

Description

technical field [0001] The invention relates to a method for making a T-shaped bar, which belongs to the technical field of ship repairing and building. Background technique [0002] According to the production plan, the workshop has undertaken a large number of shipbuilding projects, one of which is about T-shaped bar forming. According to the requirements of the production plan, the workload will continue until the second half of 2016. During this period, there will be a large number of T-shaped profiles that need to be formed. The longest T-shaped bar is about 11 meters, and the shortest is about 2 meters. There are several specifications. But the most important thing is that the panel width is 150mm and the web height is 400mm. According to the workshop’s previous molding practices: Lay the panel on the flat ground, and use the clamp crowbar to make the web perpendicular to the panel. Usually, a 10-meter-long T-shaped profile requires 3-4 people to complete the installa...

Problems solved by technology

According to the workshop’s previous molding practices: Lay the panel on the flat ground, and use the clamp crowbar to make the web perpendicular to the panel. Usually, a 10-meter-long T-shaped profile requires 3-4 people to complete the installation. The web is often broken during installation. Swing back and forth, the verticality is difficult to control, the whole process is time-consuming and laborious, and there are potential safety hazards

[0003] When welding T-shaped materials, two methods are usually used. One is pure manual welding, which has low efficiency and large deformation.

Another method is to use the CO2 trolley to automatically walk on the web. This method needs to put the assembled T-shaped bar down, and then turn it over for welding after one side is welded. The efficiency is not the highest, and it needs to be completed by manpower when turning over
