Description

Suspending wheel hub quenching furnance

One, technical field

The utility model belongs to wheel hub equipment for Heating Processing, relates in particular to the suspending wheel hub quenching furnance that wheel hub output is little, easy and simple to handle, cost of manufacture is low.

Two, background technology

In recent years, along with advancing by leaps and bounds of automotive industry technology, everybody is more and more higher to the requirement of car mass and performance, and high-performance, high-quality automobile demand amount are constantly soaring.Automotive hub is as one of core component travelling, the many factors such as its dimensional precision, surface quality and organization mechanics performance the quality good or not of automobile aluminum wheel hub, although China's tube rolling unit is reached advanced world standards, the dimensional precision of aluminium wheel hub and mechanical property can with abroad match in excellence or beauty, but hub surface quality, tissue and mechanical property etc. are still unstable.Causing the unsettled principal element of above-mentioned quality is the thermal treatment process level hysteresis of metallurgical quality and wheel hub.Current equipment for Heating Processing and technology level differ greatly, some employings partial circulating type of heating, therefore some employing systemic circulation type of heating, generally all can produce the larger temperature difference, cause thermal treatment inhomogeneous, have reduced quality product.Meanwhile, unstable due to thermal treatment (heating---insulation---cooling), can cause the unstable of wheel hub mechanical property.General similar equipment for Heating Processing also exists body of heater long, the problem that configuration is many, and this has increased cost to enterprise virtually.Generally speaking, prior art mainly exists heat treated article to be heated inhomogeneously to cause that conforming product rate is low, temperature controls the problems such as unstable, stove overall thermal efficiency is low.

Three, summary of the invention

The purpose of this utility model is exactly in order to address the above problem, for market provides a kind of wheel hub heat treating facilities that product is heated evenly, temperature control is easy, stove overall thermal efficiency is high that makes.

Main technical schemes of the present utility model is: body of heater is by metal upright post, furnace wall, furnace roof, recirculation blower, burner, the parts such as division plate and smoke discharging pipe form, described body of heater is suspending structure, material placing casing is established in its below, the dragging track of water tank and the dragging track of fire door, track is arranged on ground, track is arranged at the top of water tank, fire door is arranged on a car, the crank throw arranging with wheel shaft both sides is connected, between body of heater one side external door car guide rail, be provided with cylinder, on opposite side metal upright post, be provided with a car bumper piece, material frame carries out lifting by the chain arranging in stove.

The beneficial effects of the utility model are: owing to taking vertical hanging structure, material is raised and enters burner hearth thermal treatment being sent under quenching furnance, after having heated, fall in water tank and quench, not only rational in infrastructure, floor space is little, easy and simple to handle, cost of manufacture is low, and product is heated evenly, temperature control is easy, stove overall thermal efficiency is high, be especially applicable to wheel hub output compared with small business.

Four, accompanying drawing explanation

Fig. 1 is the utility model one-piece construction front view.

In figure: 1 is column, 2 is furnace wall, and 3 is furnace roof, and 4 is smoke discharging pipe, and 5 is fire door, and 6 is cylinder, 7 is water tank, 8 recirculation blowers, and 9 is burner, and 10 is tubaeform furnace roof, and 11 is chain, and 12 is air channel, 13 is door car, and 14 is a minute block, and 15 is material frame, and 16 is dividing plate, and 17,19 is track, and 18 is crank throw.

Five, embodiment

Take to processing the enterprise of the wheel comparatively small amt that rubs a day is example, it builds the wheel hub heat treatment furnace equipment of one 4 meters, quenching furnance is by metal upright post 1, furnace wall 2, furnace roof 3, recirculation blower 8, burner 9, the compositions such as division plate 16 and smoke discharging pipe 4, below body of heater, be provided with material frame 15, the dragging track 19 of water tank 7 and the dragging track 17 of fire door 5, track 19 is arranged on ground, track 17 is arranged at the top of water tank 7, fire door 5 is arranged on a car 13, the crank throw 18 arranging with wheel shaft both sides is connected, between body of heater one side external door car guide rail 17, be provided with cylinder 6, on opposite side metal upright post 1, be provided with a car bumper piece 14, material frame 15 carries out lifting by the chain 11 arranging in stove.While implementing the utility model, material frame 15 is interior product feed after, by motorcycle be transported to quenching furnance under, chain 11 declines, and tangles and expects, after frame 15, material frame 15 to be sling, and is suspended in burner hearth.Door car 13, under the promotion of cylinder 6, completes the sealing of a car to burner hearth by crank throw 18.After heating completes, cylinder 6 is retracted, and after fire door 5 declines, with door car, removes in the lump.Meanwhile, water tank 7 by another motorcycle be transported to quenching furnance under, chain 11 declines, the material frame 15 of splendid attire wheel hub is immersed in the water, and completes quenching.After having quenched, chain 11 is again sling and is expected the product in frame 15, and water tank is removed, and material frame 15 is positioned in motorcycle, then sends into aging oven and walks thermal treatment once.
