Make the foamed aluminum materials heating furnace
Technical field
The invention belongs to and make the foamed aluminum materials heating device technology area, be specifically related to a kind of manufacturing foamed aluminum materials heating furnace.
Background technology
At present, adopting solid pressure head THROUGH METHOD to make the used heating furnace of foamed aluminum materials is enclosed well-type electric furnace.During production, the mould that salt grain cast type is housed is put into well-type electric furnace carries out preheating, then, again with preheating mould from stove, take out and be placed on the work top, with in the aluminium liquid cast progressive die tool above the salt grain cast type, again pressure head is put in the mould again pressurization of aluminium liquid and seepage flow.Whole cast aluminum liquid and the process of aluminium liquid pressurization and seepage flow all carried out outside stove, operation is very inconvenient, the production process complexity, and Temperature Distribution can not be controlled in the stove, and the temperature of entire die is up and down equally.After mould takes out from stove, temperature can descend rapidly, mold preheating temperature is low, meeting Yin Wendu descends and makes the seepage flow deficiency, the mold preheating temperature height makes reduce die life on the one hand, can cause that on the other hand aluminium liquid leaks from gap location between top pressure head and the mould and bottom die holder, thereby cause filling the type failure, cause waste product.This method, the technology controlling and process difficulty, yield rate is low.
Summary of the invention
The object of the invention provides a kind of heating furnace of new construction, can overcome the shortcoming that prior art exists effectively.
The present invention is achieved in that the heating furnace of new construction comprises shaft, bindiny mechanism and heating etc.It is characterized in that described shaft is an opposite opened, it is to be involuted by left and right sides two halves, and middle for flexibly connecting, the bottom is equipped with movably rolling mechanism, and the multilayer heating that can regulate each layer temperature is installed in the furnace wall.
Advantage of the present invention and good effect:
1. compare with well-type electric furnace, the present invention is an opposite opened, and the bottom is equipped with scroll wheel, flexible and convenient operation.
2. the present invention is the opposite opened structure, in process of production to preheating, the cast aluminum liquid of mould and salt grain cast type, reaches the pressurization of aluminium liquid, seepage flow etc. all can be carried out in stove inner edge heating edge, can not cause mould and temperature of aluminum liquid to descend.
3. the multilayer heating that can regulate Temperature Distribution in the stove is installed in the furnace wall, the temperature of mold bottom can be controlled at the number of degrees that need, when aluminium liquid seepage flow arrives the bottom, solidify immediately, thereby prevented the leakage of aluminium liquid.

Among the figure: 1,1 '-shaft, the 2-rotational pin, the 3-heating, the 4-scroll wheel, 5-closes opening mechanism, 6-mould, 7-pressure head, 8-aluminium liquid, 9-salt grain cast type, 10-die holder, 11-base.
The specific embodiment
As shown in Figure 1, 2.Shaft of the present invention is by left and right sides two halves 1 and 1 ' combine, the centre has rotational pin 2 to connect, the multilayer heating of installing in the furnace wall 3 is resistance wire or electrothermal tube, the bottom is equipped with scroll wheel 4, close locating to install relevant opening mechanism 5, during production, open the opposite opened heating furnace, die holder 10 is fixed on mould 6 bottoms and putting into together in the heating furnace, again the salt grain is put in the mould 6, and with pressure head 7 with the compacting of salt grain, take out pressure head 7 then, with left and right sides two halves shaft 1 and 1 ' closure, and fasten by closing opening mechanism 5, and to resistance wire or electrothermal tube energising heating.When reaching preset temperature, aluminium liquid is cast in above the salt grain cast type 9, again by 7 pairs of aluminium liquid pressurizations of pressure head and seepage flow.In whole process of production, can pass through the Temperature Distribution in resistance wire or the electrothermal tube adjusting stove as required, thus each layer temperature in the control mould.
