Embodiment
The present invention is described further for specific embodiment below in conjunction with the accompanying drawings.
The production technology for the guide wheel wheel blank that the present embodiment is provided, that is to say a kind of production technology of guiding wheel rim, bag
Include following steps,
S1：Section bar is made, cross section and the guide wheel wheel blank to be produced are molded by way of rolling, extrusion or casting
The special-purpose section of the shape and size identical strip of radial section, the special-purpose section is as shown in Figure 1.
It is preferred that, in the present embodiment, the thickness of the special-purpose section left and right sides position 1 corresponding with guide wheel wheel shoulder is big
Thickness in special-purpose section intermediate flange position 2, the i.e. thickness of special-purpose section intermediate flange position 2 is thinner than conventional guide wheel wheel
The thickness of the lugs position of body, can so reduce resistance during follow-up volume circle forming step, and then reduce to volume circle forming machine
Tonnage demand, reduce production cost, because the stress of guide wheel is concentrated mainly on guide wheel wheel shoulder, special-purpose section intermediate flange
Position 2 mainly plays a part of to connect two wheel shoulders, and the reduction of its thickness can't influence the performance of guide wheel, moreover it is possible to reduce material
Cost.
In addition, being provided with the left and right of chamfer 3, i.e. special-purpose section intermediate flange position 2 at external corner on the outside of special-purpose section
Both sides are respectively arranged with chamfer 3, so also contribute to reduce resistance during follow-up volume circle forming step.Need specification
It is in the present embodiment, to be cut and be wound into towards the side in the center of circle as the inner side of special-purpose section after circle, far using special-purpose section
From the center of circle side be special-purpose section outside, the left and right two by special-purpose section of the direction of both ends of special-purpose section width
Side.
S2：Cut section bar, special-purpose section cut into multiple blanks, the length of each blank all with the guide wheel wheel to be produced
The girth of base is identical, i.e., blank is the equal of the guide wheel wheel blank after expansion, and cutting machine used in cutting special-purpose section is best
For plasma flame cutting machine.After the completion of cutting, scarf also is respectively cut out inside and outside blank two ends.
By the kerf (the end profile shape that is to say blank) formed after cutting special-purpose section is directly affected
To the welding cost and bonding strength of next step, in the present embodiment there is provided a variety of kerfs.The first kerf
As shown in figure 3, the kerf formed after cutting special-purpose section is in the shape of the letter V, suffered by during such guide wheel use
Pressure is not concentrated on whole weld seam, and bonding strength is more firm；Second of kerf is as shown in figure 4, cutting tailored version
The otch formed after material at the position 1 corresponding with guide wheel wheel shoulder of the special-purpose section left and right sides be in and special-purpose section width
Direction identical in-line, is in the shape of the letter V at special-purpose section intermediate flange position 2, guide wheel wheel shoulder position when so using
The stress time of weld seam, improve service life；The third kerf is as shown in figure 5, what is formed after cutting special-purpose section cuts
Mouth-shaped is in W fonts, namely V-shaped in pairs, and so local weld seam is not easy to crack；4th kind of kerf is as shown in fig. 6, cutting
The otch formed after special-purpose section is in and tailored version at the position 1 corresponding with guide wheel wheel shoulder of the special-purpose section left and right sides
Material width identical in-line, is in W fonts at special-purpose section intermediate flange position 2, so can equally improve and use
Life-span；5th kind of kerf is as shown in fig. 7, cut the otch formed after special-purpose section in the special-purpose section left and right sides with drawing
It is in the in-line being arranged in parallel with the width of special-purpose section at the corresponding position 1 of guide wheel wheel shoulder, in the middle of special-purpose section
Lugs position 2 is so easy to cutting in the in-line that the angle with the length direction of special-purpose section is acute angle；6th kind of otch shape
Shape is as shown in figure 8, the one end for the blank that cutting is obtained has a projection 4, and the other end has the groove coordinated with the projection 4,
Wherein projection 4 is located at special-purpose section intermediate flange position 2, can so avoid welding from misplacing, and improves welding quality；7th kind is cut
Mouth-shaped is as shown in figure 9, the kerf formed after cutting special-purpose section is in the width parallel arrangement with special-purpose section
In-line, such kerf is easy to cut and welded, but bonding strength is relatively low, it is adaptable to which size is relatively small
Guide wheel；As shown in Figure 10, the structure sets the side wall of groove on the basis of the 6th kind of kerf 8th kind of kerf
It is in step-like to be set to, and certainly, corresponding projection sidewall shape is also configured as stepped, is so conducive to further increase connection
Intensity；As shown in figure 11, the kerf formed after cutting special-purpose section is in in-line, and a word for 9th kind of kerf
The angle of the otch of shape and the length direction of special-purpose section is acute angle, is so easy to cut and welds, and bonding strength is also greater than
Seven kinds of kerfs, it is adaptable to the guide wheel of medium size；Tenth kind of kerf as shown in figure 12, cuts institute after special-purpose section
The kerf of formation is in circular arc；Kerf as shown in figure 13, cuts the otch formed after special-purpose section in 11st
It is in and the word of special-purpose section width identical one at the position 1 corresponding with guide wheel wheel shoulder of the special-purpose section left and right sides
Shape, is in circular arc at special-purpose section intermediate flange position 2.
It should be noted that in the first above-mentioned kerf and second of kerf, and should not kerf pair
Claim arrangement, i.e., the length of V-shaped both sides oblique line can be different, likewise, in actual production, can also be in above-mentioned otch shape
Deformation obtains new kerf on the basis of shape.
S3：Volume circle shaping, is wound into circle so that blank head and the tail are mutually supported one using volume circle forming machine by blank
Rise, now, weld groove is formed between corresponding two scarves in blank head and the tail two ends.
S4：Wheel blank is welded, the head and the tail two ends of material base are welded to each other, guide wheel wheel blank is formed, its structure is as shown in Figure 2.
The present invention is described in detail above in conjunction with specific embodiment, but embodiments of the present invention and not only limited
In above-mentioned embodiment, those skilled in the art can make various modifications according to prior art to the present invention, and these are belonged to
Protection scope of the present invention.
