Description

A kind of hot spinning expanding device
Technical field
The invention belongs to forklift hubs to be flared technical field, and in particular to a kind of hot spinning expanding device.
Background technology
Forklift hub is the important feature part in relation to fork truck traffic safety, quality and reliability be not only related to vehicle and The safety of passengers inside the car and goods and materials, and the property such as also affect the stationarity in vehicle travel process, maneuverability, comfort 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
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of hot spinning expanding device is provided, is overcome 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.
