Description
Technical field
It the utility model is related to aluminium product technical field, more particularly to a kind of full-automatic short aluminium bar heated line.
Background technology
At present in industrial aluminum profile extruding production, generally long aluminium bar is heated using combustion type fast stove, is passed through
The scissors of hot shears, aluminium bar is cut, so that obtaining extruding produces the required short aluminium bar of high temperature.When industrial aluminum profile quality will
When asking higher, then short aluminium bar is heated using combustion type fast stove, by hot peeling machine, aluminium bar outside diameter is peelled off into 3-5mm,
The required short aluminium bar of high-cleanness, high high temperature is produced so as to obtain extruding.Because long aluminium bar is using the high temperature after hot shears, obtained
Short aluminium bar, Leading Edge Deformation is big, and length direction is bent to form at deformation, causes hot peeling machine can not carry out peeling, therefore, this two kinds
Technique, i.e. " long rod heating+hot shears Cutting process " are with " stub heating+hot soarfing skin technique " in same combustion type rapid heating furnace
On, for the short aluminium bar of the satisfactory high temperature of offer that cannot be general on same extruder.At present, the more rod stoves occurred in market
Mainly the air in burner hearth is heated by burner, more aluminium bars side by side are heated using hot gas.More rods
There are preheating time length for stove, it is impossible to the defects of realizing gradient-heated.The structure that single rod stove uses is the spray by furnace body both sides
Rifle carries out single aluminium bar individually the directly mode of flame heating.Although single rod stove can shorten the pre-warmed time, plus
The high-temperature flue gas produced in thermal process can be exhausted directly to outside furnace body, cause the waste of thermal energy.
In metal thermoforming process, before thermoforming, first metal stock is heated.Such as aluminium section bar processing,
First aluminium bar is carried out being heated to required moulding process temperature, then by molding die extrusion bar.It is presently used for aluminium bar heating
Equipment generally use rotary type heating furnace, its structure type is that a rotating turret is installed in burner hearth, and rotating turret has circumferential cloth
If with installing the casing of aluminium bar.During work, feed mechanism pushes aluminium bar in casing from the feed inlet of burner hearth, fuel
Stove chamber inner combustion is sprayed into from the nozzle of burner hearth sidewall, aluminium bar is heated, aluminium bar is during heating as rotating turret turns
Dynamic, when aluminium bar rotates after a week, temperature just reaches the temperature needed for moulding process, at this time, complete heating aluminium bar can by by
Feed mechanism push into aluminium bar promote from the discharge port of the burner hearth other end and be pushed out coming, enter in next moulding process and extrude
Shaping.This rotary funace is primarily present following shortcoming：Due to being to employ one whole casing to be sleeved on outside aluminium bar, in burner hearth
The thermal current of burning is to be difficult to directly heat aluminium bar, even if opening up through hole on casing, thermal current directly heats aluminium bar
Area or limited, thus this influences whether the heat temperature raising speed of aluminium bar, and aluminium bar heats time length to be produced；Aluminium bar is from entering
Stove into the whole heating process come out of the stove, aluminium bar with rotating turret rotate one week, carry all the time by casing, such aluminium bar into
All be when going out casing with casing static friction, aluminium bar disengaging casing resistance it is big, have some setbacks, it is necessary to relatively high power feed mechanism come
Complete the push of aluminium bar.
103375988 A of Chinese utility model patent CN disclose a kind of full-automatic aluminum bar heating furnace, the burner hearth in furnace body
There is insulating layer in outside, and the import of burner hearth is corresponding with feeding mechanism to be connected, and is had sprocket wheel on the sprocket holder at furnace body both ends, is sheathed on sprocket wheel
On chain through in burner hearth, the rotation of driving device drive sprocket, unicom in the air outlet and burner hearth of forced draft fans, on burner hearth
There is a chimney with extraneous unicom, engagement plate is high-end with chain to be located at furnace outlet and align and be connected, engagement plate bottom and feeding
The high-end connection of passage, the bottom of feeding passage are connected with blow tank, blow tank linking just corresponding with the feed inlet of aluminium extruding machine,
The controller control feeding mechanism is acted with driving device, and the utility model realizes the full-automatic of aluminium bar and is input in burner hearth
It is output to again in aluminium extruding machine after the heating of footpath and carries out aluminium extrusion, whole process without human intervention, improves production efficiency；But
It is that this utility model can not realize the self-feeding of aluminium bar and stablize movement in heating furnace, can not also realize the logical of aluminium bar
With heating.
Aluminium section bar heats forged uses aluminum-bar heating furnace, and stub stove is that long aluminium bar is sawed into required short aluminium bar, through short
Aluminum-bar heating furnace is heated to extrusion temperature (420-520 DEG C), resupplies extruder use, generally uses the box aluminium of simple gate at present
Rod heating furnace, workpiece heat in heating furnace, just take out workpiece when temperature, which reaches, to process, due to for simple gate it is box,
Needed when taking workpiece whole oven door opening, cause heating furnace heat largely to scatter and disappear, energy expenditure is big；If necessary to add again
Hot second workpiece, then need to close fire door and heat up again heating, the temperature in heating furnace is returned to the temperature originally set
Under state, and the workpiece in heating furnace could add new workpiece only after being fully completed and carry out heating use, cause workpiece
Process-cycle length, while influence with batch work-piece quality.
The stub stove of domestic production at present is generally driven using chain or roller, and fire door can not completely enclose, heat energy loss
Greatly, aluminium bar limited amount in stove, in order to reach production capacity, using quick mode of heating, energy consumption is big, aluminium bar energy consumption per ton about 70m3 days
Right gas, and aluminium bar needs first to carry out homogenization, it is of high cost.
