Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment：A kind of wheel rim flaring device of the utility model, as shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, it is wrapped
Include：
There is retainer on pedestal, pedestal；Retainer is cylinder, and its center portion has an axis hole, circumferential wall last week
To several bar-shaped troughs of setting；
The tapered shaft 1 moved axially under outside power drive in the retainer axis hole, its head is tapered diameter
Taper；
Several locating pieces 2 radially slided in the bar-shaped trough of retainer, locating piece root, which is shunk, to be in strip, bar shaped portion
Constitute and be slidably matched with the bar-shaped trough, and bar shaped portion bottom surface is resisted against on the conical nose periphery of tapered shaft 1；When tapered shaft 1
During axial movement, locating piece 2 is radially slided；
The enlarging block 4 being fixed on the locating piece 2, enlarging block 4 has an inside and outside circle side face, inner peripheral surface and locating piece it is outer
Circumference is fitted, and outer peripheral face is the arc being adapted to wheel rim；On the section of enlarging block 4, middle part has a plane, and both sides have the respectively
One inclined-plane 41, the second inclined-plane 42, middle plane and the first inclined-plane 41, the second inclined-plane 42 wrap into what is be adapted to wheel rim inner peripheral wall
Profile；The angle of first inclined-plane 41 and the axis of tapered shaft 1 is less than the angle on the second inclined-plane 42 and the axis of tapered shaft 1；
And the side of the first inclined-plane 41 is arranged at the limited block 6 of size when controlling the wheel rim to extend out.Limited block is securable to
Pedestal, is also securable in external agency.
Have in the middle part of the periphery of enlarging block 4 and adjustment block 5 is set in groove, groove, the top surface of adjustment block 5 and the first inclined-plane 41, the
Two inclined-planes 42 wrap into the profile being adapted to wheel rim inner peripheral wall.The internal diameter of convenient adjustment enlarging workpiece, to ensure workpiece size.
Block 3 is set on locating piece 2, and block 3 has hook part；Block 3 is located at the side of the second inclined-plane 42 and hook part is withheld
On enlarging block 4.Enlarging block 4 is more stably mounted on locating piece 2, be difficult to slide axially, be difficult circumferential deflection.
The equidistant annular array of each locating piece 2, and it is symmetrical one by one along the center line of tapered shaft 1.This structure, in locating piece footpath
To when being displaced outwardly extruding wheel rim, each position stress is more balanced, and balance is more preferable, beneficial to the formed precision for improving wheel rim.
At least there is the duct 8 with connecting external air source in an enlarging block 4, duct 8 has passes to the first inclined-plane respectively
41st, two outlets on the second inclined-plane 42.After wheel rim shaping is extruded, duct 8 is ventilated, and passes through the first inclined-plane 41, second inclined-plane 42
Enlarging of two outlets to wheel rim two ends is tested；For example in 12 pieces enlarging blocks, duct is set in one piece of enlarging block topmost, made
Have enlarging cracking detection function, access 2-6Bar air pressure, during compression flare keep sealing, once butt welding position
Cracking, air pressure declines, and equipment is recognized by sensor, and equipment stops, and prevents the workpiece of cracking to be flowed into subsequent processing, damages
The equipment and mold of bad subsequent handling.
It should be noted that because the gradient of wheel rim two ends enlarging differs, thus in compression flare wheel rim two ends deformation
Power is not of uniform size, and produced axial thrust load is not of uniform size, so as to cause wheel rim to have the tendency moved axially.In this regard, this reality
In new, limited block 6 is set in the side of the first inclined-plane 41；Because the angle on the first inclined-plane 41 and the axis of tapered shaft 1 is less than the
The angle on two inclined-planes 42 and the axis of tapered shaft 1, thus wheel rim when extending out axial force point to the side of the first inclined-plane 41, entered by limited block 6
Row axial limiting, so as to avoid enlarging from being wheel rim axial movement and cause flaring precision not enough.Therefore, limited block 6 both has limit
The radial dimension of effect of system, has the effect of axial limiting again.
Mechanism of the present utility model is, using being divided into some pieces（Such as 12 pieces）Enlarging block be arranged on equipment positioning
On block, tapered shaft by axial stretching motion drive locating piece and enlarging block radially to extend out or shrink and by the enlarging of wheel rim two ends simultaneously
Control the size of enlarging.
In use, the workpiece being welded is transported to enlarging station, it is inserted in, tapered shaft is protruding, drives enlarging block outward
Expanding, carries out enlarging to workpiece until reaching the size of requirement, tapered shaft is retracted thereafter, takes out workpiece.
The example above explanation is only used for illustrating spirit of the present utility model, when actually implementing, and remains and becomes some
The drive device of shape and extension program, such as tapered shaft, can be using the electronic, device powered by conventional energy such as pneumatically or hydraulically；In another example,
Enlarging, which completes post-positioning block and enlarging block, to be needed to fold to complete homing action, in this regard, hand-reset can be used, that is, is inserted in next
Each locating piece and enlarging block are pushed back until locating piece is resisted against on tapered shaft manually when the wheel rim of enlarging；Can also be using automatic
Reset, such as, in annular locating piece periphery, some cylinder drivings or spring driven briquetting are set, each locating piece is applied
Point to the active force of tapered shaft axis direction, you can allow locating piece and enlarging block reset when tapered shaft is retracted, then remove workpiece.
Although oneself is through having shown and described embodiment of the present utility model, it will be understood by those skilled in the art that
Can these embodiments be carried out with a variety of changes, modification, practicality in the case where not departing from principle of the present utility model and objective
New and modification, scope of the present utility model is limited by claim and its equivalent.
