Description
Technical field
The present invention relates to the manufacturing process of track girder, particularly relate to a kind of manufacturing process of hot rolling printed line cold bed trolley track beam.
Background technology
At present, hot rolling printed line cold bed trolley track beam (calling beam-and-rail in the following text) is the walking track of supporting plate dolly in the cold bed, carrying steel plate to be cooled above the dolly.More than this part length 12000mm, and the thinnest place of wall thickness has only about 10mm, and this part is a massproduced part.Traditionally, be after integral solder is finished, with the whole processing of heavy duty machine tools.Because structure is thin, after the integral solder distortion serious, have in addition can't correct; Because the heavy duty machine tools equipment cost is very high, caused the manufacturing cost of this part too high, and the manufacturing cycle is long.Special for some structures, add man-hour in integral body, also need to be equipped with special-purpose cutter head and cutter and just can carry out.Such as the structure among Fig. 1, just need diameter less than the extension bar of 120mm and the forming-tool corresponding with the orbital plane gradient.This has just further increased manufacturing cost, has prolonged the manufacturing cycle.This class part requires with short production cyclely when producing in batches, and cost is low, the product percent of pass height.In the face of this all requirement, the traditional handicraft innovation is imperative.
Summary of the invention
The manufacturing process of the hot rolling printed line cold bed trolley track beam of product percent of pass height, low cost of manufacture, manufacturing cycle weak point when the present invention provides a kind of batch process the in batches for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of manufacturing process of hot rolling printed line cold bed trolley track beam, comprise welding sequence and machining processes, described welding sequence is to weld by the structure sub-unit, postwelding transfers shape to correct separately, and assembly welding is shaped then; Described machining processes is the preceding segmental machining of track plate weldering, and joint is reserved the expansion joint, and alignment polishes; After the track girder assembly welding is shaped, transfer shape to correct, through Ageing Treatment, whole processing bottom surface and keyway etc.
The present invention can also adopt following technical measures:
The manufacturing process of described hot rolling printed line cold bed trolley track beam is characterized in that: described welding sequence comprises weldering beam body, weldering bearing, assembly welding beam body and bearing, weldering track plate.
The manufacturing process of described hot rolling printed line cold bed trolley track beam, it is characterized in that: the method for described welded grider body comprises: symmetrical two these parts openings are relatively spoted weld together, about symmetrical welding simultaneously, the postwelding oscillating aging, then, left and right sides two parts are taken apart, transfer shape separately.
The manufacturing process of described hot rolling printed line cold bed trolley track beam is characterized in that: adopt model located lateral track plate with control its spacing size when the method for described welded rails plate comprises assembly welding.
The manufacturing process of described hot rolling printed line cold bed trolley track beam is characterized in that: described track plate connector adopts the hypotenuse butt joint.
Advantage and good effect that the present invention has are: the present invention can satisfy the beam-and-rail batch production requirement.At the serious problem of post welding distortion, adopt the method for pressing the welding of structure sub-unit, welded at every turn and transferred shape to correct separately, do not allow distortion superpose.Because in rivet welding spare, i.e. bending of the distortion of single-degree-of-freedom is rectification easily, and the distortion of two or more frees degree is promptly twisted and is difficult to correct.Simultaneously, because adopted the method for welding,, enhance productivity so when producing in batches, can realize pipelining by the structure sub-unit.At the high problem of heavy duty machine tools equipment cost, adopt the preceding segmental machining of track plate weldering, joint is reserved the expansion joint, and alignment polishes.So both save the holding time of heavy duty machine tools equipment, shortened the process-cycle again.The present invention has guaranteed the qualification rate of product, has saved the holding time of heavy duty machine tools equipment, has reduced manufacturing cost, has shortened the manufacturing cycle.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 to Fig. 7.
The present invention includes welding sequence and machining processes, described welding sequence is by the welding of structure sub-unit, and postwelding transfers shape to correct separately, and assembly welding is shaped then; Described machining processes is the preceding segmental machining of track plate weldering, and joint is reserved the expansion joint, and alignment polishes; After the track girder assembly welding is shaped, transfer shape to correct, through Ageing Treatment, whole processing bottom surface and keyway etc.
See also Fig. 4 to Fig. 6,009 blanking of track plate divides 6 sections, and first section 1,4 in stage casing, 1 of rear, about 2 meters/section, 45 ° of hypotenuse butt joints are adopted in the joint, and machine adds workshop processing upper and lower surface and side;
This track plate survives size 22mm, for raising the efficiency, selects the thick hot rolled plate blank of 25mm for use, and the flame cutting stock is processed upper and lower surface to thickness 22mm with grinding machine.Dividing into about 2 meters/section, is in order to process with the grinding machine of stroke 2.2m.45 ° of hypotenuses butt joints are adopted in the joint, are in order to seamlessly transit during through the joint at wheel, to reduce and impact.
See also Fig. 1 to Fig. 3, channel-section steel 001, angle steel 010～014, steel plate 015～017 blanking, assembly welding becomes the beam body after each part straightening, and postwelding is transferred shape.
The beam body is a kind of structure based on channel-section steel 001, because structure is thin and elongated, post welding distortion is serious.In order to reduce distortion, the method that the present invention takes is that symmetrical two these parts openings are relatively spoted weld together, about symmetrical welding simultaneously, the distortion about making is cancelled out each other, the postwelding oscillating aging is eliminated the part welding stress.Then, left and right sides two parts are taken apart, transfer shape separately, guarantee whole linearity in 3mm, and local linearity is in 1mm/1000mm, to reduce the accent shape amount of whole postwelding.
See also Fig. 1, steel plate 002～008 blanking, assembly welding becomes bearing after each part straightening, and postwelding is transferred shape.
With described beam body and bearing assembly welding beam in aggregates, postwelding is transferred shape.
Because between track plate 009 and the channel-section steel 001 is discontinuous welding, the distortion that causes is not too large, thus the accent shape of this step, the flatness and the linearity of track plate 009 after having determined substantially to survive.
With track plate 009 and unjointed beam assembly welding, postwelding is transferred shape, oscillating aging;
In this step, the spacing dimension of track plate 009 needs emphasis control, and the measure that the present invention takes is to use model to work the time, sees also Fig. 4, guarantees the spacing dimension of track plate quickly and accurately.Simultaneously, the plane can detect the integral planar degree of orbital plane easily with respect to the size of datum level on the sample by measuring at diverse location.
Beam-and-rail behind welding fabrication favourable turn is added the workshop, whole processing bottom surface and keyway etc.
The track that the present invention makes, each size all can meet design requirement, and all in 3mm, local linearity and flatness are all in 1mm for orbital plane integral planar degree and linearity.
