Embodiment
As shown in Figures 1 to 4, a kind of spinning contour roll forming composite structure for being used to there is inner tube of a tyre rim contour to shape, by workpiece pressure
Plate 1, spinning mandrel 2, thick spinning roller 3, smart spinning roller 4 and rear correction of the flank shape roller 5 form, and work clamp 1 is arranged on the upper end of spinning mandrel 2
Face, thick spinning roller 3, smart spinning roller 4 are respectively distributed in around spinning mandrel 2 and are close to setting with spinning mandrel 2 and form, rear correction of the flank shape
Roller 5 is installed on the rear of spinning mandrel 2；Described spinning mandrel 2 include spinning mandrel top 201, spinning mandrel bottom 202,
Ejector beam 203 and guide rod 204, the ejector beam 203 run through the center of spinning mandrel top 201 and spinning mandrel bottom 202, and
Spinning mandrel top 201 and spinning mandrel bottom 202 are vertically connected with, while guide rod 204 is some also extends through spinning core
Mould top 201 and spinning mandrel bottom 202 are distributed in around ejector beam 203.
As shown in 1 to Fig. 3, described smart spinning roller 3 is specifically distributed in the left-hand portion of spinning mandrel 2, and smart spinning roller 4 is specific
It is distributed in the right side position of spinning mandrel 2.
Work clamp 1 is used to push down the top of spinning mandrel 2 during spinning and is connected thereto integrally, strengthens spinning mandrel 2 and revolves
Rigidity when turning；Thick spinning roller 3 is arranged in the right and left of spinning mandrel 2 with smart spinning roller 4, enters walking according to certain track respectively
Position feeding, spinning is carried out to workpiece, the work circular arc of thick spinning roller 3 is larger, and the spinning that can carry out large inflow revolves without causing
Unstability is pressed, the work circular arc of smart spinning roller 4 is smaller, and the correction of the flank shape of the further small amount of feeding can be carried out to the workpiece of thick supination；Correction of the flank shape afterwards
Roller 5 is placed in the rear of spinning mandrel 2, when spinning finishes, radially promotes, and edging is carried out to workpiece.
Blank corresponding to spinning contour roll forming combination process is both ends open and the cylindrical member after double end bell mouth expanding, and it is high
Degree is less than spinning mandrel 2；Cylindrical member upper end open amplitude is smaller, and roller 5 of being practiced Buddhism or Taoism after convenience is last is extruded it, is got into work
Make the interior concave space formed after pressing plate 1 is bonded with the top of spinning mandrel 2, and form circlip groove；Cylindrical member lower ending opening amplitude compared with
Greatly, facilitate thick spinning roller 3 to carry out lower end part rotation with smart spinning roller 4 to squeeze, to form reverse 90 degree of double-bending, the gear as tire
Side.
Blank after enlarging is inserted in spinning mandrel 2, and its lower ending opening is propped up the step of spinning mandrel bottom 202
Place is simultaneously positioned, and afterwards under the promotion of each ultromotivity, thick spinning roller 3, smart spinning roller 4 and rear correction of the flank shape roller 5 are started working successively, to work
Part carries out spinning, edging respectively.
As shown in figure 3, the main function of thick spinning roller 3 is to carrying out first time rotation by the cylindrical member of double end bell mouth expanding
Pressure, the thin effect of rotation is played to the middle part face of cylinder of cylindrical member；Because the lower ending opening of cylindrical member props up spinning mandrel top 201,
In the case of and upper end limited in lower end is free, cylindrical member is occurred opposite with the spinning roller direction of motion by the position metal material of spinning
Flowing, i.e., up flow so that cylindrical member highly increases and by spinning position wall thickness reduction；Treat that thick spinning roller 3 walks to tubular
When at part lower ending opening, because with the corresponding position of spinning mandrel bottom 202 larger space be present in cylindrical member lower end horn mouth,
Therefore the horn mouth of cylindrical member is gradually inwardly extruded and is intended to be bonded with the outer surface of spinning mandrel bottom 202 by thick spinning roller 3,
So that the horn mouth deformation of cylindrical member, forms reverse double-bending.
As shown in figure 3, the main function of smart spinning roller 4 is then to carry out second to the workpiece after the rotation of thick spinning roller 3 is squeezed to revolve
Pressure, further revolve the middle part face of cylinder of thin cylindrical member so that workpiece further increases, and exceeds the height of spinning mandrel 2, together
When upper port prop up work clamp 1, for smart spinning roller 4 because its work circular arc is smaller, another effect is to make cylindrical member lower port
Reverse double-bending further deform so that the inwall of cylindrical member is further bonded with the outer surface of spinning mandrel bottom 202, most
End form is into reverse 90 degree of double-bending.
As shown in figure 4, rear correction of the flank shape roller 5 after the smart spinning of spinning roller 4, workpiece height reach highest when start radially to push away
Enter, the upper end of rear correction of the flank shape roller 5 contacts the upper port outer wall of cylindrical member first, and it is inwardly squeezed into work clamp 1 and rotation
The interior concave space that pressure core top 201 is formed when being bonded, and ultimately form local inner concave and the structure locally turned up --- back-up ring
Groove；The interior recess of the lower end in contact cylindrical member lower port of correction of the flank shape roller 5, carries out final correction of the flank shape, so far formed with interior after afterwards
The profile of tire wheel rim, unnecessary material is removed using turning process afterwards, obtains the finished product of inner tube of a tyre wheel rim.
The utility model is matched on special spinning machine, for dual-port in horn-like cylindrical member carry out spinning and
Contour roll forming, and the profile of inner tube of a tyre wheel rim is finally made, used as there is inner tube of a tyre wheel rim.
