Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, institute in being described below to the embodiment of the present invention
The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only some implementations of the present invention
Example, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to present invention implementation
The content and these accompanying drawings of example obtain other accompanying drawings.
Fig. 1 is the T-steel material processing unit (plant) top view that the present invention is provided.
Marked in figure as follows：
11- transmitting devices；12- welders；13- apparatus for correcting；
131- flame heating guns；132- flame heating guns；133- flame heating guns；134- flame heating guns.
Embodiment
In order that those skilled in the art more fully understand technical scheme, below in conjunction with the accompanying drawings and by specific
Embodiment further illustrates technical scheme.
The embodiments of the invention provide a kind of T-steel material antidote, to T in the streamline weld job of T-steel material
Structural section carries out flame straightening, including：
According to the height of T-steel material, the height of flame heating gun is adjusted；
Because the rectangular area that the processing of T-steel material is the formation at the top from the bottom of web and wing plate carries out heating pair
Face is welded, because the web height of the T-steel material of different model is different, according to the height of T-steel material, regulation flame heating gun
Height is heated to the top of web, enables to be heated evenly at the top and bottom of web, so as to effectively reduce abdomen
Plate deforms, so as to play a part of correcting T-steel material, can effectively shorten the improvement time, improves the production effect of T-steel material
Rate, it is to avoid stagnation behavior occurs in streamline, improves the space availability ratio of processing factory building.
Specifically, the center line of flame heating gun is adjusted to the top of the web of T-steel material, due to flame heating
The flame that rifle sprays is in dispersion shape, and the center line of flame heating gun is adjusted to the top of the web of T-steel material, can be made
The most outer for obtaining the flame for the dispersion shape that flame heating gun sprays is under the top of web, flame can be made full use of to heat
The flame that rifle is ejected, improves the utilization rate of flame, saves the energy.
T-steel material is welded, be ensure that after welding sequence with regard to correction process can be carried out, caused by now welding
The deformation of T-steel material is also fixed without cooling completely, it is possible to effectively shorten the improvement time, saves the space profit of processing factory building
With rate.When the weld seam of T-steel material is initially rectified to apparatus for correcting, opening needs the flame heating gun of work；Due to web and
Wing plate is not just to be welded most starting contact position, so in one section of beginning not weld seam, now can not
Open flame heating gun, otherwise will because web top it is heated and bottom is not heated, and cause the deformation of T-steel material.
When the weld seam of T-steel material is initially rectified to apparatus for correcting, it is possible to which opening needs the flame heating gun of work, such web
It can be heated up and down, so as to realize the correction for T-steel material.Correction is filled when the weld seam of T-steel material terminates to rectify
When putting, the flame heating gun having already turned on is closed, because the tail position that web is contacted with wing plate does not have weld seam yet, so needing
Stop flame heating gun work in weld seam clearing end, realize the correction to T-steel material.
The embodiments of the invention provide a kind of more specifically T-steel material antidote, make in the flowing water wire bonding of T-steel material
Flame straightening is carried out to T-steel material in industry, including：
By the distance at the top of web of the center line of flame heating gun away from T-shaped sheet material be 10mm~20mm, select this away from
The top edge of web is placed exactly in from for ensureing that flame heating gun sprays the edge of scattering dress flame, this and flame heating gun
It is comprehensive away from close to its side distance it is also related, the flame that can be ejected with maximized utilization flame heating gun, save energy
Source.
T-steel material is welded, although the welding manner of T-steel material is two-sided welding, but can select different numbers
Amount bonding wire is welded, in order that web is heated evenly up and down in welding and correction process, reaches the work of correction T-steel material
With, it is necessary to according to the different welding manner of T-steel material, it is determined that needing the flame heating gun of work, include the position of flame heating gun
Put and quantity.When welding is using the welding of two-sided monofilament, selection is located at each flame heating gun in transmitting device both sides, two fire
Flame heating gun is symmetrical arranged relative to transmitting device, is welded using monofilament, the flame flow negligible amounts of welding, so in order to match
The flame flow of welding, also selects corresponding flame flow quantity during correction, thus ensure web by thermal balance, reach preferably
T template rectification effects；
When welding is using two-sided double wire welding, selection is located at each two flame heating guns in transmitting device both sides, side
Two flame guns and two flame guns of opposite side are symmetrical arranged relative to transmitting device, principle ibid, flame flow during correction
Flame flow quantity when quantity is with welding is corresponding, so as to realize preferable T-shaped plate rectification effect.
Choose after specifically used flame heating gun, T-steel material is welded by welder, when T structural sections
Weld seam initially rectify to apparatus for correcting when, opening need the flame heating gun of work, when T-steel material weld seam terminate rectify pair
During apparatus for correcting, the flame heating gun having already turned on is closed.
Monitor the flame temperature T on flame heating gun in real time by temperature measuring set, control flame temperature T 650 DEG C~
800 DEG C, by substantial amounts of experiment, 650 DEG C~800 DEG C can guarantee that the rectification effect of T-steel material preferably, if in addition, detected
Flame temperature T on flame heating gun does not reach this temperature range, it is necessary to increase the discharge capacity of flame heating gun, if super
Go out, then need to reduce discharge capacity or temporary close flame heating gun carries out temporary transient cooling treatment.
Temperature measuring set is infrared temperature measuring instrument, and infrared measurement of temperature has the response time fast and non-contacting advantage, is fitted
Close the temperature of detection flame.
Flame is neutral oxy-acetylene flame, when the effect of oxygen and acetylene compare for 1~1.2 when, during produced flame is referred to as
Property flame, be adapted to for alloy straightening.
