Abstract
A kind of Huo Qu Baogangs processing method of angle steel tower, in turn includes the following steps：（1）A plane is processed at the back side of the curved position of angle steel fire bending system, bores a fabrication hole in the plane；（2）Redundance on leg of angle is cut off by bending angle gas flame cuttiug processed, otch is connected to fabrication hole lower edge；（3）It is after fiery song that angle steel is curved by predetermined angular system；（4）The gap cut open is welded.Mother metal can not be damaged in cutting by method of the present invention, while ensure to make chamfering in curved position angle steel and remove completely；Tear damage would not occur when so the bent system of fire is curved, and ensure that welding quality, solve the problems, such as that existing process Huo Qu Baogangs crudy is unstable.
Description
Technical field
The invention belongs to a kind of angle steel tower Huo Qu Baogangs processing technique field, more particularly to a kind of angle steel tower Huo Qu Baogangs
Processing method.
Background technology
Because angle steel tower has the features such as manufacturing procedure is few, process automaticity is high, cost is relatively low, angle steel tower exists
Transmission line of electricity has obtained substantial amounts of application.Wherein in the processing and manufacturing process of angle steel tower welding sequence few in number, fire is bent
The crudy of Baogang is always difficult to preferably be controlled.The Huo Qu Baogangs processing method generally used at present is by Baogang
The angle that one limb is bent as required slices off unnecessary part with gas flame cuttiug, by the bent system of Baogang's fire it is curved after, then scarfing welded
It is connected to together.Because there is an Inner arc chamfering leg of angle root, artificial gas flame cuttiug operation is less susceptible to control again, cutting it is too many
Mother metal can be damaged, if Inner arc, which is not cut off, can cause mother metal tear damage in bending again.Huo Qu Baogangs are mainly used in
The place of tower material varied angle connection, is important primary structure member, the quality of Huo Qu Baogangs quality directly affects the quality of steel tower.
So a kind of new Huo Qu Baogangs processing method is needed to ensure the crudy of Huo Qu Baogangs.
The content of the invention
The present invention is intended to provide a kind of realize convenient, the processing method for improving the angle steel tower Huo Qu Baogangs of product quality.
In order to solve the above technical problems, the invention provides following technical scheme：A kind of Huo Qu Baogangs of angle steel tower add
Work method, in turn includes the following steps：
（1）A plane is processed at the back side of the curved position of angle steel fire bending system, bores a fabrication hole in the plane；
（2）Redundance on leg of angle is cut off by bending angle gas flame cuttiug processed, otch is connected to fabrication hole lower edge；
（3）After fiery song that angle steel is curved along bending line system, bending angle processed is by predetermined angular；
（4）The gap cut open is welded.
Step（1）Preceding to need diagonal steel surface to be cleared up, method for cleaning is：Washing or air-flow blow；Wherein, washing uses
For running water.
After diagonal steel is cleared up using washing step is being carried out, it is necessary to dry（1）, wherein, the method dried is：Naturally dry in the air
It is dry.
Step（1）In in the method for processing a plane at the back side of the curved position of angle steel fire bending system be：Using file plus
Work.
Step（1）In, a fabrication hole is bored using the spiral bits of φ 12, the internal diameter of the fabrication hole is φ 12.
By above technical scheme, beneficial effects of the present invention are：Can be in cutting by method of the present invention
Mother metal is not damaged, while ensures to make chamfering in curved position angle steel and removes completely；It would not be torn when so the bent system of fire is curved
Rhegma is hindered, and ensure that welding quality, solves the problems, such as that existing process Huo Qu Baogangs crudy is unstable.
Brief description of the drawings

Fig. 2 is the Huo Qu Baogangs finished product obtained using the method for the invention.
Embodiment
A kind of Huo Qu Baogangs processing method of angle steel tower, in turn includes the following steps：
（1）A plane is processed at the bent back side for making curved position of the fire of angle steel 1, bores a fabrication hole 3 in the plane.In this implementation
In example, it is in the method that the bent back side for making curved position of the fire of angle steel 1 processes a plane：Processed using file.
Wherein, in order to improve final product quality, in step（1）Before need the surface of diagonal steel 1 to be cleared up, method for cleaning is：
Washing or air-flow blow；Wherein, wash use for running water.After diagonal steel 1 is cleared up using washing step is being carried out, it is necessary to dry
（1）, wherein, the method dried is：Naturally dry.In the present embodiment, cleared up using the surface of running water diagonal steel 1, can be with
Remove the impurity on the surface of angle steel 1；And using the method for naturally dry the surface of chemical substance diagonal steel 1 can be avoided to cause to damage.
In the present embodiment, the temperature of running water is advisable with 20 ~ 40 °, preferably 35 °, so as to avoid angle steel 1 from heat loss or refrigerating loss occur.
Meanwhile in the present embodiment, the method for boring a fabrication hole 3 in the plane is：One is bored using the spiral bits of φ 12
Fabrication hole 3, the internal diameter of the fabrication hole 3 is φ 12.
（2）Redundance on the limb of angle steel 1 is cut off by bending angle gas flame cuttiug processed, otch is connected to the lower edge of fabrication hole 3.
（3）Angle steel 1 made along bending line 2 after fiery bent curved, bending angle processed is by predetermined angular.
（4）The gap 4 cut open, which is welded, can form finished product.
Method of the present invention realizes the Huo Qu Baogangs processing of angle steel 1, does not damage mother metal in cutting, while ensure to make
Chamfering removes completely in curved position angle steel 1；Tear damage would not occur when so the bent system of fire is curved, and ensure that welding
Quality, solve the problems, such as that existing process Huo Qu Baogangs crudy is unstable.
