Regarding the methods of preparing grooves in steel plates
Thread Content
Regarding the preparation of grooves in steel plates, there are two questions I would like to ask: 1. What equipment is used for preparing such grooves? The most basic equipment is flame cutting, which is used to create V-shaped grooves; these grooves are then manually polished. For thicker steel plates, U-shaped or X-shaped grooves are required. What equipment do you use in your factories to carry out this work? As of now, I am aware of three types of equipment: the first is a large vertical milling machine, the second is a mobile beveling machine, and the third is a beveling machining tool. 2. Sequence of groove preparation: After the steel plate is cut to size, 2 A-groove (longitudinal) grooves and 2 B-groove (circumferential) grooves need to be prepared. The first method involves completing all 4 grooves right after cutting the steel plate, followed by rolling it into a cylindrical shape and welding it. The second method involves first preparing the A-grooves, rolling the plate and welding it, then preparing the B-grooves, and finally carrying out welding to adjust the thickness. Which process sequence is usually chosen, and if the second method is selected, what is the reason?
Generally, it is more convenient to mill the bevel in a flat configuration; if the tube section is first rounded, milling the bevel becomes less convenient, so manual grinding is used instead.
1. I don’t know what that machine is called (like in Figure 3). 2. When the thickness of the cut edge on the cylinder is significant, the second method should be used; otherwise, it will take on an open-mouthed shape after rolling
Flame cutting (mainly for carbon steel and low-alloy steel), edge trimmers, moving beveling machines, large milling machines, etc
The device shown in Figure 3 is called a groove machining machine. Depending on the type of machining head installed, it can be referred to as a steel plate edge planer or a steel plate edge miller; alternatively, both types of machining heads can be installed simultaneously, in which case it is called a steel plate planing and milling machine.
