Can, this requires wheel hubs to have the characteristics that fatigue strength is high, rigidity and elasticity are good, size and shape precision is high, light weight.
The purpose that wheel hub is flared process is to expand at wheel rim straight tube position to the size needed for lower one of finishing step, under
One step process preform, flaring precision will directly affect the machining dimension at follow-up wheel rim position.And existing hot spinning expands
Mouth device, mainly controls the size of forklift hub flaring by the dropping distance of flaring die, often leads to forklift hub flaring
Size and design value deviation are larger, or even forklift hub can be caused breach occur, to greatly affect forklift hub forming
Precision afterwards and intensity.
Invention content

The deficiencies in the prior art, reasonable design is compact-sized, wheel hub to be processed is fixed in fixation by clamping device
On disk, on fixed disk setting movable plate, flaring die is driven to carry out high speed rotation by driving device, it will be for processing by hydraulic cylinder
Wheel hub close to flaring die, by its flare formation.
A kind of hot spinning expanding device, including flaring die, fixed frame, hydraulic cylinder, movable plate and fixed plate, the activity
Plate is set on fixed frame column supported on both sides, and the movable plate upper end is equipped with fixed plate, is rotated in fixed plate and is provided with flaring
Mould, the flaring die back side connect driving device, positioning sleeve are equipped on the outside of the flaring die, and the movable plate is equipped with side mould, institute
The Bian Monei stated is equipped with heating rod, and the side mould is made of several pieces points of valve blocks, and every piece is divided the bottom of valve block to be equipped with sliding block, sliding block
It is arranged in the guide-track groove on movable plate top, the outside of side mould is matched with the taper surface on positioning sleeve inner wall, the inner wall of side mould
It is equipped with and is equipped with bed die, the center of bed die and movable plate with the matched arcwall face of forklift hub outside wall surface, the middle part of movable plate
Place is equipped with through-hole, and ejection block and cylinder are equipped in the central through hole of bed die；The movable plate lower end is equipped with hydraulic cylinder.
The hydraulic cylinder lower end is supported by support plate.
The flaring die is equipped with multiple idler wheels between being contacted with fixed plate.
Compared with prior art, beneficial effects of the present invention：
Wheel hub to be processed is fixed in by clamping device on fixed disk by the present invention, and movable plate is arranged in fixed disk
On, drive flaring die to carry out high speed rotation by driving device, it, will by hydraulic cylinder by the wheel hub of generation processing close to flaring die
Its flare formation；Being accurately positioned for flaring die is realized by positioning sleeve, and forklift hub flaring is ensured by flaring die and Bian Mo
Precision avoids being flared insufficient caused by forklift hub flaring process or crosses flaring problem, with efficient, precision is high, finished product
The high advantage of rate.
