Example Embodiment

[0022] The steps of the present invention will be described in detail below in conjunction with specific examples:

[0023] 1. For a certain type of boiler produced, first use the computer and Solidworks program to establish a three-dimensional graphic corresponding to the boiler cylinder in the computer according to the design requirements of the boiler cylinder tube hole;

[0024] 2. Expand the three-dimensional graphics into two-dimensional graphics, and divide them into blocks according to the distribution of pipe holes. The example picture is divided into four areas, as shown in the attached image. figure 2 Shown

[0025] 3. Save the unfolding solidworks 2D graphics as CAD format drawings;

[0026] 4. Retouch the two-dimensional CAD graphics, delete the redundant lines that appear after the graphics are expanded, and determine the baseline of each block template;

[0027] 5. Convert CAD format drawings to CorelDRAW vector format, and then edit and convert them into engraving proce...

Abstract

The invention provides a boiler cylinder body pipe hole face mold and a manufacturing method thereof. According to the method, by means of a computer and relative programs, a three-dimensional diagram corresponding to a boiler cylinder body is built in the computer according to requirements for design of boiler cylinder body pipe holes, then the diagram is spread to form a two-dimensional diagram, lines are revised, reference lines of regions are determined according to pipe hole distribution regions, a vector diagram is formed through conversion, a carving program is formed through conversion, hole profile lines and the reference lines are carved on a face mold material, and the pipe hole face mold is manufactured. According to the boiler cylinder body pipe hole face mold manufactured in the method, the size is accurate, the efficiency is high, the cylinder body pipe holes do not need cut for a second time, the face mold can be repeatedly used, and the face mold is suitable for large-scale production.

Description

technical field [0001] The invention relates to a scribing template for processing pipe holes and a manufacturing method thereof, in particular to a boiler shell pipe hole scribing template and a manufacturing method thereof, belonging to the technical field of industrial boiler processing. Background technique [0002] The boiler body is connected to multiple sets of water and fire pipes, such as figure 1 As shown, before welding with the water and fire tubes, it is necessary to cut holes through the tubes on the boiler shell, and these holes include non-radial tube holes. All tube holes are arranged evenly and evenly spaced according to the direction of the circular drum, but after the circular drum is unfolded, the arrangement of the tube holes will change, and the horizontal and vertical spacing will gradually change from the middle to both sides. The distance between each section is different, and the hole in the middle is approximately circular, and the hole on the ou...
