Description
Technical Field
The invention relates to the field of hydraulic machinery, in particular to a forming mechanism and a forming method of a large-tonnage brick press.
Background
The forming process structure of the prior known super-tonnage ceramic press comprises the following steps: the mold comprises a mold frame with a double transmission belt and without a mold core, a mold frame with a single transmission belt and a mold frame without a transmission belt. These ultra-large tonnage ceramic presses typically produce ceramic plates having a length of more than 3 meters and a width of more than 1.2 meters.
Fig. 1 shows a "double conveyor belt no-core mold frame" type structure, which includes an upper conveyor belt 1 ', a lower conveyor belt 2', an upper mold core 3 'and a lower mold core 4'. The structure is characterized in that the lower mold core 4 'moves upwards, the lower conveying belt 2' is pressed to be in contact with the powder 5 ', the powder is pressed and molded, and the green bricks after powder molding are conveyed out of the interior of the press through the lower conveying belt 2'.
Fig. 2 shows a "single conveyor belt core" type structure, which includes a lower conveyor belt 2 ', a lower core 4 ' and an upper core 3 '. The structure is characterized in that the upper mold core 3 'directly contacts the powder 5', the powder 5 'is pressed and molded, and the green bricks molded by the powder are conveyed out of the interior of the press through the lower conveying belt 2'.
Fig. 3 shows a "belt-less, core-and-frame" type of structure, which is specifically composed of an upper core 3 ', a lower core 4', a shim plate 6 'and a frame 7'. The powder 5 'is distributed in the space formed by the lower mold core 4' and the mold frame 7 ', and then the upper mold core 3' presses the powder. After the powder is pressed into green bricks, the mould frame 7' descends, and the green bricks are sent out of the press by a skip car or other equipment.
Mold in the fig. 1 and 2 structures: during the process of powder pressing, when the powder is subjected to pressure, the powder can naturally spread in all directions due to the fact that the periphery of the powder is not supported by a frame with strong rigidity, most of areas with uneven pressure are formed at the periphery of a green brick beyond a mold core, the areas cannot be used and need to be cut off, and therefore huge waste is caused, especially for green bricks with large sizes.
Mold in the fig. 3 configuration: in the process of powder pressing, the size of the powder is consistent with the assumed value due to the limiting effect of the die frame on the powder. However, because the size of the green brick is too large, the short side of the green brick (the long side cannot be pushed because of the space limitation of the vertical columns and the like on the left side and the right side of the press) is pushed by the general brick pushing mechanism, and the green brick is easily damaged. The green brick is not transported smoothly in this respect as a conveyor belt.
At present, a press with small tonnage adopts a structure as shown in figure 4. Comprising an upper mould core 3 ', a lower conveyor belt 2 ' and a backing plate 6 '. The structure is characterized in that: the inner wall of the upper mold core 3 'is provided with a cavity, and powder is arranged between the lower conveying belt and the upper mold core 3'. The powder is pressed by the upper die core to be pressed into green bricks, and then the green bricks are conveyed by the lower conveying belt to leave the press. Although the problems of powder waste and smooth green brick transportation can be solved, the length and the width of large-size ceramics are large, the gap area 8 'of the stroke of the die core and the conveying belt is quite large, the pressing area of the press is large, the quantity of powder is large, the position of the upper die core, which is in contact with the powder, is the gap area 8' in the figure 4 instead of the green brick part which is actually needed, and the quality of the formed green brick is easily influenced. Therefore, this structure not only requires a greater pressing force, consumes more energy, and easily causes instability in the green brick quality. Specifically, when a large-size ceramic plate is pressed by using the forming mechanism having the above-described structure, if the gap area 8 ' is not parallel to the two planes of the inner wall of the upper core 3 ', the blank compression ratio of the gap area 8 ' is significantly higher than that of the blank at the position of the cavity of the inner wall of the upper core 3 ', and therefore the applied pressure is mainly concentrated on the gap area 8 '. At this time, if the pressure on the inner wall of the upper mold core 3' meets the process requirement, the pressure of the whole press must be increased, and energy is wasted. In addition, in the application technology of the press with small tonnage, a method for improving the parallelism of the gap area 8 'corresponding to the upper die core 3' and two planes of the inner wall of the upper die core 3 'is adopted by people to reduce the influence of the strong reverse thrust of the blank in the gap area 8' on the parallelism of the formed green bricks, but for a large-size ceramic plate die, the processing difficulty of the die frame is greatly increased, and the manufacturing cost is improved.
