Embodiment Construction

[0030] The method of opening a large number of numerically controlled holes on the stainless steel cylinder is: firstly, typesetting the cylinder in the axial and circumferential directions according to the material plate width according to the figure, using 3D drawing software to draw a three-dimensional diagram of the cylinder opening, and according to the layout drawing , expand the three-dimensional map of each barrel section from the longitudinal weld, import the expanded view of each barrel section into the CNC cutting machine control system, and set the increase amount, arc length, cutting direction and cutting sequence in the CNC control system , use plasma to cut out each hole intermittently; leave 4 points at the polar axis so that the cut part is still connected with the base material, plan off the connection part between each hole and the base material after forming and welding, and grind the required hole direction according to the diagram, Finally, assemble and we...

Abstract

The invention provides a method for numerical control forming of a large quantity of holes in a stainless steel cylinder and belongs to the technical field of stainless steel carbonizers and similar containers or towers. The method comprises the following steps: a cylinder hole forming three-dimensional diagram is drawn by use of three-dimensional graphics software, the three-dimensional diagram of each section of the cylinder is unfolded according to a layout and converted into a graphic format which can be recognized by a numerical control cutting machine, an addition amount, a striking arc length, a cutting direction and a cutting order are set in a numerical control system according to the material of the cylinder and a plasma cutting method, all holes are cut by use of intermittent plasmas, the sections of the cylinder are molded and the unfitness of butt joint of end faces are controlled, and after welding is finished, the connection parts of the holes are planed and polishing is carried out to obtain the desired hole orientation. The method has the advantages that the problem of difficult, unsafe and inaccurate forming of a large quantity of holes by use of riveting after the stainless steel cylinder is molded is solved, and horizontal welding of 198 cooling water pipes in a stainless steel carbonizer with the cylinder.

Description

technical field [0001] The invention belongs to the technical field of manufacturing stainless steel carbonization towers and similar containers or towers, and in particular provides a method for opening a large number of numerically controlled holes on a stainless steel cylinder. Background technique [0002] At the beginning of this year, our company undertook a batch of manufacturing tasks for stainless steel carbonization towers. The stainless steel carbonization towers have an inner diameter of DN2000mm and a height of 30 meters. The centerline of each row of tubes is horizontal. Using our company's conventional method of drilling holes on stainless steel cylinders, firstly drill a large number of holes, use machining to drill positioning holes and then mill out each hole on a boring machine, but the diameter of the cylinder is 2000mm, and the drilling machine's capacity cannot reach it The cylinder is first formed, welded, then scored, and carbon arc gouging out each ...
