Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Clod wash channel-section steel forming method designed by the present invention comprises the following steps:
A, by three-dimensional launch software cold bending tank steel sample 1 (as shown in Figure 1, 2) is carried out setting-out launch become expansion plane 3, as shown in Figure 3, and on the termination launching plane 3, reserve die mould surplus 3.1 and be conducive to the breach 3.2 of hand cut, as shown in Figure 4, and breach 3.2 against the drift angle of die mould surplus 3.1;
B, according to the required accessory 6 of the shape cutting launching plane 3, after cutting, utilize the size that tape measure comparison launches plane 3 that the size of accessory 6 is checked;
C, the herringbone accessory 8 that accessory 6 is converted into symmetry by bender is utilized (to be converted into the herringbone accessory of symmetry, when being easy to later use casted die mould die mould, die mould position can be corrected accurately, and internal stress during abundant release herringbone accessory cold roll forming), detailed process is: as shown in Figure 5
It is profiled piece owing to launching plane 3, during bending, there is no suitable anchor point, therefore need to make bending location-plate 5;
The bending location-plate 5 made is placed on the backstop 4 of bender;
After accessory 6 is positioned by bending location-plate 5, utilize tape measure and angle square 2 to measure die mould height dimension and the die mould root size of accessory 6, then die mould height dimension and die mould root size are corrected;
After having corrected die mould line, accessory 6 is bent until accessory top is adjacent to the upper insert of bender, form symmetrical herringbone accessory 8;
D, the opening up of herringbone accessory 3 centering are put in the counterdie position of center line of casted die mould 7, and guarantee that herringbone accessory 8 all claims to the gap on casted die mould 7 both sides, as shown in Figure 6, then carry out die mould and form die mould accessory, after herringbone accessory 8 die mould becomes die mould accessory 9, as it is shown in fig. 7, utilize angle square and tape measure to check the height dimension of die mould accessory, root size, opening size, perpendicularity and web plane degree; If (bigger than the root size of die mould accessory or die mould accessory the perpendicularity of the opening size of die mould accessory does not reach technology requirement, then the upper die mould insert of casted die mould and the gap of down-pressing type insert are adjusted; If web plane degree does not reach technology requirement, then reserved certain reversible deformation between plane and upper die mould insert lower plane in the down-pressing type insert of casted die mould, for offsetting the rebound amount of herringbone accessory die mould. )
E, by breach 3.2 the die mould surplus of die mould accessory 9 carried out cutting obtain required clod wash channel-section steel, as shown in Figure 8, the assembly particularly as follows: cutting profiling 11 and pattern locating piece 10 are welded into a whole, and black box is placed on the termination that die mould accessory 9 needs to cut, position. The end face of cutting profiling 11 of the present invention includes cambered surface 12 and along the outward extending horizontal plane 13 of cambered surface 12, namely the cambered surface 12 of cutting profiling 11 is alignd reserved with the intersection of horizontal plane 13 breach 3.2 top and the end of the close position of web 1.1, pattern locating piece 10 are against die mould accessory 9 edge, thus die mould accessory 9 is accurately positioned;
After die mould accessory 9 is had good positioning, the die mould surplus 3.1 that hand cut is reserved is carried out by breach 3.2, and receive during hand cut the circular arc cut on acnode position and die mould accessory carry out round and smooth excessively (adopt round and smooth excessively, it is to avoid boss and indenture occur);
After f, die mould surplus 3.1 to die mould accessory 9 are cut, when one flat board is leaned against the web position of cutting position and die mould accessory termination, if flat board and web position gap are not more than 2mm, then cutting position is polished, scarfing cinder, namely obtain required clod wash channel-section steel.
Utilize bender that accessory is converted into the herringbone accessory of symmetry, casted die mould is used to be put in place by herringbone accessory die mould, cutting profiling, pattern locating piece is utilized to find the processing method that the cut point of future insufficiency carries out cutting accurately, can ensure that the Forming Quality of die mould accessory, it is ensured that die mould accessory opening size is consistent with root size; And reserve hand cut breach, it is also ensured that hand cut can have a point of penetration accurately during cutting, to ensure the cut lengths of die mould accessory.
