Description

Technical Field

[0001] This invention relates to the field of iron tower technology, specifically to a method for manufacturing a bending welded plate for the front and side surfaces of an iron tower. Background Technology

[0002] In the structure of transmission line towers, the front and side panels connected to the main materials often employ welded structures, such as those at slope changes, curved arms, and cat-head crossarms. Currently, tower layout using 3D modeling software is common, offering advanced layout capabilities, but its handling of the aforementioned structures is not ideal, requiring manual adjustments after software rendering. When the tower slope is significant, the side panels have large bending angles, and the welded structure between the side and front panels can easily lead to misalignment of bolt holes with the auxiliary angle steel connections after assembly and welding. This ultimately poses safety hazards during on-site tower erection and installation, affecting tower quality. Therefore, a method for fabricating bent and welded plates for the front and side surfaces of the tower is proposed to address this problem. Summary of the Invention

[0003] The purpose of this invention is to provide a manufacturing process for the bending and welding plate of the front and side panels of a steel tower, which solves the problem of misalignment of the bolt holes of the side panel and the auxiliary angle steel when the front and side panels are welded.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for manufacturing a bending welded plate for the front and side surfaces of a steel tower, comprising the following steps:

[0005] Step 1: First, draw a 1:1 size template of the front panel according to the structure of the drawing. Based on the specifications of the main materials at the top and bottom of the drawing and the distance between the top and bottom of the front panel, draw the position of the side panel on the front panel. According to the thickness of the side panel, draw the position of the bending point of the tool.

[0006] Step 2: Draw a 1:1 size template for the side panel. Based on the specifications of the main materials at the top and bottom of the drawing and the standard distance between the top and bottom of the side panel, draw the upper and lower welding lines of the side panel. The intersection of the upper and lower welding lines of the side panel is the bending point of the fire curve. The bisector of the angle between the two lines is the oblique fire curve.

[0007] Step 3: Based on the distance from the connecting hole of the main material of the front connecting plate to the bending point of the tool, draw the position of the front hole on the side panel. Based on the distance difference between the connecting holes of the main material of the front and side panels, draw the position of the side hole on the side panel according to the position of the front hole.

[0008] Preferably, in step 1, when the plate thickness is less than 8mm, the bending point position can be determined based on a plate thickness of 0.35t; when the plate thickness is 8mm or more, the bending point position can be determined based on a plate thickness of 0.5t.

[0009] Compared with the current technology, the beneficial effects of the present invention are as follows: The present invention draws the front panel, draws the position of the side panel on the front panel, draws the position of the tool bending point according to the thickness of the side panel, then draws the side panel, draws the upper and lower welding lines of the side panel, the intersection of the upper and lower welding lines of the side panel is the bending point of the fire curve, and the bisector of the angle between the two is the oblique fire curve. According to the distance from the connecting hole of the main material of the front connecting plate to the tool bending point, combined with the distance difference of the connecting holes of the main material of the front and side panels, the position of the side hole is drawn on the side panel according to the position of the front hole. The side panel is manufactured according to the above process method. After assembly and welding, the installation fits without gaps, and the bolt through hole rate is 100%. Detailed Implementation

[0010] The present invention will now be described in more detail by way of examples. These examples are merely illustrative and do not limit the scope of the present invention in any way.

[0011] This invention provides a technical solution: a method for manufacturing a bending welded plate for the front and side surfaces of a steel tower, comprising the following steps:

[0012] Step 1: First, draw a 1:1 size template of the front panel according to the structure of the drawing. Based on the specifications of the main materials at the top and bottom of the drawing and the distance between the top and bottom of the front panel, draw the position of the side panel on the front panel. According to the thickness of the side panel, draw the position of the bending point of the tool.

[0013] Step 2: Draw a 1:1 size template for the side panel. Based on the specifications of the main materials at the top and bottom of the drawing and the standard distance between the top and bottom of the side panel, draw the upper and lower welding lines of the side panel. The intersection of the upper and lower welding lines of the side panel is the bending point of the fire curve. The bisector of the angle between the two lines is the oblique fire curve.

[0014] Step 3: Based on the distance from the connecting hole of the main material of the front connecting plate to the bending point of the tool, draw the position of the front hole on the side panel. Based on the distance difference between the connecting holes of the main material of the front and side panels, draw the position of the side hole on the side panel according to the position of the front hole.

[0015] Example 1:

[0016] First, based on the structure in the drawings, draw a 1:1 scale template of the front panel. According to the specifications of the main materials at the top and bottom of the drawings and the distance between the top and bottom of the front panel, draw the positions of the side panels on the front panel. Based on the thickness of the side panels, draw the bending point positions for the cutting tool. Next, draw a 1:1 scale template of the side panels. Based on the specifications of the main materials at the top and bottom of the drawings and the distance between the top and bottom of the side panels, draw the upper and lower welding lines of the side panels. The intersection of the upper and lower welding lines of the side panels is the bending point for the fire curve. The bisector of the angle between these two lines is the oblique fire curve. Based on the distance from the connecting hole of the main material of the front connecting plate to the bending point for the cutting tool, draw the position of the front hole on the side panel. Based on the difference in distance between the connecting holes of the main materials of the front and side panels, draw the position of the side holes on the side panel according to the position of the front hole.

Generally, when the thickness of the plate is less than 8mm, the bending point position can be taken as 0.35t plate thickness. When the thickness of the plate is 8mm or more, the bending point position can be taken as 0.5t plate thickness. Draw a 1:1 scale template of the side panel. According to the specifications of the main materials at the top and bottom of the drawings and the distance between the top and bottom of the side panel, draw the upper and lower welding lines of the side panel.
