Abstract
The invention relates to a continuous heat-treating furnace for automobile hubs, comprising a conveyer belt 1 penetrating the heat-treating furnace, which is characterized in that: three combustion furnace chambers 11, a hot-blast nozzle 2 and a return airway 3 are arranged above the conveyer belt 1; a frequency conversion fan 4 is arranged in the combustion furnace chambers 11; a gas burner 5 is arranged on the wall; a temperature controller 10 is arranged on the bottom of the heat-treating furnace; a photoelectric inductor 8 and a PLC controller 9 are arranged at the exit end; the casing material adopts aluminum silicate fiber and stainless steel. The continuous heat-treating furnace for automobile hubs has the advantages that: the traditional push rod mechanism and ball race conveying device are changed into the high-temperature resistant chain as the conveyer belt; the automobile hubs are laid in parallel in monolayer; the PLC variable program controller is utilized to automatically control the whole heat-treating processing flow of getting into and out of the blast furnace; the labor intensity is reduced; the residual heat can be utilized again to save heat energy; the automobile hub can be heated uniformly; and the timing and temperature determining are precise.
Description
One, technical field
The present invention relates to the metal heat treatmet device, specifically automobile wheel hub continuous heat-treating furnace.
Two, background technology
Thermal treatment is one of fundamental technology important in the mechanical industry, and to improving product inner quality and work-ing life, the reinforcement product at home and abroad market competitiveness has very important effect.Because thermal treatment has directly influenced the inner quality of product on the one hand, also can directly influence dimensional accuracy of products on the other hand, improper as thermal treatment, all that has been achieved is spoiled can to cause manufactured product.Therefore, how improving and improve the level and the frock corresponding with it of thermal treatment process, is the target of the diligent pursuit of technologists all the time.At present, the method that is adopted on traditional automotive hub heat-treatment production line is: the automotive hub that pours into is overlayed in the metallic charge frame, with push-down mechanism whole frame wheel hub is advanced in the heat treatment furnace, the shortcoming of this method maximum is that lower floor's wheel hub produces distortion because of the extruding that is subjected to upper strata wheel hub gravity, and wheel hub is heated inside and outside causing inhomogeneously because of stacking, and thermal effectiveness is poor; Another is that raceway carries production line, and its main drawback is that the wheel hub that is heated usually can produce halfway and stagnates and be subjected to squeezing the phenomenon of rolling and being out of shape in course of conveying, and these two kinds of production lines all be unable to do without hand-manipulated, and operational difficulty, labour intensity are big; And the metallic charge frame is also heated after entering in the stove simultaneously, absorption portion heat energy inevitably, and at the bottom of the thermo-efficiency, energy consumption is big.
Three, summary of the invention
The present invention is directed to the defective of above-mentioned existence, the technical scheme of the technical issues that need to address and proposition is: on original traditional automotive hub heat-treatment production line the push-down that adopts and rollaway type structure to change to simple in structure, high temperature resistant chain be conveying belt, automotive hub is carried and is taked individual layer to keep flat, implement full automatic control with sophisticated high-tech product PLC variable program controller, automotive hub is heated evenly, can not be out of shape, reach the purpose that labour intensity and energy consumption are low and can successively heat-treat.
The present invention realizes by following scheme, the heat treatment furnace middle part is provided with the conveying belt 1 that runs through furnace chamber, three burning furnace chambers 11 place the heat treatment furnace top, burn in the furnace chamber 11 frequency conversion fan 4 is housed, be equipped with fuel burner nozzle 5 on the wall, be provided with hot-blast spray nozzle 2 over against conveying belt 1 below frequency conversion fan 4, air-return duct 3 is positioned at hot-blast spray nozzle 2 avris; Photoelectric sensor 8 and PLC controller 9 place the heat treatment furnace exit end, and temperature control meter 10 is installed on the bottom of heat treatment furnace.The shell of heat treatment furnace is formed with aluminum silicate fiber warming plate 6 and stainless steel lined 7; Treatment temps are 540 ℃ in the burning furnace chamber 11, error≤± 5 ℃, and conveying belt 1 is made up of the refractory metal chain.

Five, embodiment
Be described further below in conjunction with the implementation process of accompanying drawing automobile wheel hub continuous heat-treating furnace of the present invention:
The shell of automobile wheel hub continuous heat-treating furnace of the present invention is made up of stainless steel lined 7 and aluminum silicate fiber warming plate 6, the total wall thickness of shell 〉=350 millimeters; The heat treatment furnace middle part is provided with the conveying belt 1 that runs through furnace chamber, and conveying belt 1 is made up of the refractory metal chain; The heat treatment furnace top is equipped with three burning furnace chambers 11, burning furnace chamber 11 places the heat treatment furnace top, in the burning furnace chamber 11 frequency conversion fan 4 is housed, rear wall is equipped with fuel burner nozzle 5, be provided with hot-blast spray nozzle 2 below the frequency conversion fan 4 over against conveying belt 1 (on automotive hub 12), for raising the efficiency, the chain-type conveying belt of automobile wheel hub continuous heat-treating furnace of the present invention is an example to be provided with 4, once carries 4 automotive hubs during conveying side by side.Air-return duct 3 is positioned at hot-blast spray nozzle 2 avris; Photoelectric sensor 8 and PLC controller 9 place the heat treatment furnace exit end, and temperature control meter 10 is installed on the bottom of heat treatment furnace.
The whole process of automobile wheel hub continuous heat-treating furnace of the present invention is to finish the continuous production action under the instruction of PLC Controlling System, in specific time automatic feed and blanking: the conveying belt before being positioned at automobile wheel hub continuous heat-treating furnace keeps flat aluminium alloy wheel hub of vehicle 12 individual layers that pour on 4 conveying belt 1 of transfer at device portal, then, open PLC controller 9, enter the full automatic control pattern, and start three the burning frequency conversion fans 4, fuel burner nozzle 5, photoelectric sensor 8, temperature control meter 10; According to the processing condition of setting, reach temperature required after, start 4 conveying belt arranged side by side 1, along with the conveying belt 1 of chain-type moves forward, place 4 automotive hubs 12 on the conveying belt 1 to deliver in the stove simultaneously, the hot blast that is produced by the frequency conversion fan 4 of burning furnace chamber 11 is heated by hot-blast spray nozzle 2, and warm air beating automotive hub 12 is after air-return duct 3 the wheel hub preheating of surplus heat second stage employ to next procedure, reaches energy-conservation purpose; At last, the automotive hub 12 after certain hour is handled with certain temperature enters down quenching process from the outlet of heat treatment furnace by conveying belt 1 output, so goes round and begins again.
