Description
Technical Field
The invention relates to the technical field of autoclaved aerated block production, in particular to a continuous automatic forming die and a forming process for autoclaved aerated blocks.
Background
The steam-compressed air concrete block is made up by using calcareous material (such as water and stone) and siliceous material (such as sand, powdered coal and slag) as adjuvant, adding aluminium powder as air-entraining agent, stirring with water, casting, gas-producing expansion, pre-curing and cutting, and curing by high-pressure steam.
In the continuous production process of autoclaved aerated concrete blocks, a mold box with an opening at the top is generally used as a mold for molding, the mold box is sent into a pre-curing chamber to be primarily shaped by virtue of a ferrying mechanism or a conveying line after mud pouring is finished, the pre-cured blocks are shaped but not cured completely, thus, large-sized blocks can be cut into required small-size blocks through a cutting device at the moment, the cut blocks are directly sent into a high-pressure steam curing furnace to be cured, in the process, the mold box can expand due to gas after the pre-curing is finished, the blocks can only deform upwards under the limitation of the mold box, the pre-cured and primarily molded blocks are in a state that the top is ridged upwards, so that the main time-consuming step of cutting is to cut the uneven protrusions at the top, the raw material waste of the ridging part is serious, the cutting time is longer, the efficiency of the whole fashioned of building block has been influenced, this kind of mould bottom plate supports the mode of building block in addition, because can't carry out further protection to the building block, can't directly cut the building block through the blade at the cutting process, for example, when transversely cutting, the transverse cutting speed is too fast can produce transverse impact force to the building block, can lead to the building block to support unstable problem that produces the slope and rock, further lead to the incision to be uneven, consequently, the current cutting of building block also can only take wire cutting mostly, and the cutting speed is slower, the building block lateral wall is because comparatively level and smooth, the cutting thickness is thin, the cutting consuming time is shorter, the process of main consuming time is the ridging position at building block top still, the cutting at ridging position and the clearance of residue after the cutting are also inconvenient, need large-scale cleaning or adsorption mechanism to arrange the waste material at ridging position after the top cutting from the building block top.
In addition, because demolding operation is needed, a buckle or other mold closing and opening mechanisms are generally arranged on the mold box and are mainly used for leaking formed building blocks for cutting after the pre-curing is finished, a side rotary demolding mode is generally arranged on the common mold box, namely, the peripheral side plates at the top of the bottom plate can be rotated and unfolded, but the bottom plate of the mold box cannot be separated from the building blocks in the mode, at the moment, the initially formed building blocks are easy to be extruded and deformed, the building blocks cannot be clamped and moved through a large clamp, the bottom plate for supporting the building blocks cannot be pulled out, only the mold can be cleaned and oiled for use after the cutting and high-pressure steam curing of the building blocks are finished, on one hand, the whole mold box can increase conveying load along with the cutting and curing processes of the building blocks, on the other hand, mainly, the space of a high-pressure steam curing furnace is limited, the traditional side rotary mold box occupies a large space laterally after demolding, the traditional mold box can cause the reduction of the use efficiency of the high-pressure steam curing furnace, the production efficiency of the whole production line is affected, and if the detachable mold box is adopted, the disassembly working procedures are needed to be increased between the processes of the cutting working procedures, and the production cycle is greatly affected; if the side plate is adopted to be pulled away, the adsorption force between the building block and the inner wall of the die is larger because the building block is expanded and formed in the pre-curing process, the pulling away process easily causes the building block to be pulled away and moved along with the side plate of the die, the part of the building block is away from the bottom plate which is supported, the building block is deformed, even if the dead weight of the building block is larger, the self weight of the building block can be overcome to be kept on the bottom plate, the condition that the building block is displaced along with the pulling away action can also exist on the inner wall of the side plate of the die which is pulled away, the side edge of the building block is easy to be pulled upwards to deform, the demolding process is difficult, and the demolding action easily possibly produces moving interference on the completely uncured building block, so that the building block is deformed.
In summary, the mold is not only used for the precutting and forming of the building blocks, but also can directly influence the subsequent cutting process, and the subsequent cutting and curing process also constrains the mold, so how to cooperate with the precutting, cutting and high-pressure steam curing process to realize continuous and efficient production, and the formed mold box becomes an important technical break.
Based on the above, the invention designs a continuous automatic forming die and a forming process for autoclaved aerated blocks, so as to solve the problems.
