Background technique

The refractory brick mold is the key equipment in the production process of refractory bricks. Its working conditions are extremely harsh, and it is subjected to high-stress abrasive wear and stress fatigue cracks of hard refractory particles. Therefore, the performance of the refractory brick mold will directly affect the production efficiency and quality of the refractory brick. The refractory brick molds currently used must be replaced and repaired after being used thousands of times. During brick making, the molds are often wiped to prevent the molds from sticking. The density of the upper and lower bricks is inconsistent; the replacement and repair of the mold requires manual work under the pressure head of the press, which is very dangerous. At present, the molds of brick presses in the refractory industry have generally used metal splicing molds. The advantages of this mold are low cost, easy to replace, and easy to maintain. The disadvantage is that the draft angle is large, and the density of the pressed bricks is not uniform. , The continuous operation time is short and the service life is short. At the same time, the structure and use of cylindrical refractory bricks are different from standard bricks and other perforated bricks. Therefore, there are higher requirements for the appearance and density of cylindrical refractory bricks. The outer formwork generates tension when the cylindrical refractory brick is extruded, and it is easy to cause damage to the refractory brick when the inner formwork and the outer formwork are demoulded.

After the pressing is completed, the outer side plate can be dropped first, so that the outer ring of the pressed cylindrical refractory brick is exposed. The cylindrical refractory brick is automatically pressed. Machine mould, during the pressing process, the cylindrical refractory brick generates tension.

The rod uses hydraulic oil to push the mandrel down. The structure is very ingenious and takes up little space. The lowering of the side plate lifting connection and the lowering of the mandrel will not interfere with each other.

3. The fully automatic hydraulic brick press for cylindrical refractory bricks uses a distribution trolley to move the homogenizer laterally. The feeder can evenly feed the material powder into the mold cavity to ensure the quality balance of each part of the cylindrical refractory bricks and improve the service life of the refractory bricks; the middle frame is also set on the floating mold frame, so that the middle frame can be used when pressing the bricks.

4. During the process of feeding the material powder into the mold cavity evenly by the homogenizer, the floating mold frame drives the side plate and the mandrel to rise gradually. When the material is finished, the side plate and the mandrel rise to the height set by the mold cavity. Compared with the past, the side plate and the mandrel are raised to the position at one time, and then the powder is fed into the cavity. This application can make the powder be better dispersed into the cavity.

detailed description

Fig. 1 ~ 5 is the best embodiment of this tubular refractory brick automatic press mould, full-automatic hydraulic brick press and brick pressing process, below in conjunction with accompanying drawing 1 ~ 5 the present invention is described further.

Referring to Fig. 1, the cylindrical refractory brick automatic press mold includes an upper formwork 8, a lower formwork 2 and a middle frame, the upper formwork 8 is lifted and arranged above the lower formwork 2, the middle frame includes a mandrel 3 and a side plate 6, and the mandrel 3 is set on the inner side of the lower formwork 2, and the side plate 6 is set on the outer side of the lower formwork 2. The middle frame and the lower formwork 2 are lifted relative to each other to form an annular mold cavity. The connection part and the mandrel 3 are relatively movable, and the side plate lifting connection part pushes the mandrel 3 to rise, and the mandrel 3 is connected with a mandrel demoulding mechanism to drive it down. In this application, the mandrel 3 utilizes an independent mandrel demoulding mechanism to realize demoulding. After the pressing is completed, the outer side plate 6 can be dropped first, so that the outer ring of the pressed cylindrical refractory brick is exposed. The cylindrical refractory brick is automatically pressed. Machine mould, during the pressing process, the cylindrical refractory brick generates tension. When the restraint of the side plate 6 is lost, the cylindrical refractory brick will expand radially outward to a certain extent, releasing most of the tension. At this time, the core It is much easier to remove the shaft 3. Even if the mandrel 3 is clamped by the cylindrical refractory brick, the mandrel 3 can be pulled out downwards through the mandrel demoulding mechanism, which solves the problem that the side plate 6 and the mandrel 3 are easy to demould at the same time. It causes quality defects such as cracks in cylindrical refractory bricks, and the wear of the mold is reduced, the service life of the mold is improved, and continuous production can be guaranteed.

The upper formwork 8 is fixed on the lower side of an upper mold support 1, and the lower formwork 2 is a cylindrical shape adapted to the mold cavity. In this embodiment, the side plate lifting connection part includes a beam 5 and a connecting column 9, and the upper and lower ends of the connecting column 9 The side plates 6 and the beams 5 are fixedly connected respectively, and the side plates 6 are driven up and down by the beams 5 . The lower template 2 is fixed on the lower mold support 4, and the beam 5 is lifted and lowered between the two lower mold supports 4. The mandrel 3 is cylindrical, and the mandrel demoulding mechanism is a mandrel lowering cylinder 7 arranged on the inner side of the mandrel 3 .

When the beam 5 rises, it will push the side plate 6, the mandrel 3 and the oil delivery rod 701 to rise synchronously. There is no hydraulic oil in 701, the beam 5 will drive the side plate 6 to descend, and the beam 5 will drive the oil delivery rod 701 to slide downward, and the mandrel 3 may be pressed by the cylindrical refractory brick and cannot fall. Finally, inject hydraulic oil into the oil delivery channel 702 of the oil delivery rod 701. After the hydraulic oil enters the actuating chamber, it will push the mandrel 3 to fall so as to complete the demoulding of the mandrel 3. The use of the oil delivery rod 701 can ensure that the crossbeam 5 pushes the side plate 6 It rises synchronously with the mandrel 3, and when the beam 5 descends, it only drives the side plate 6 and the oil delivery rod 701 to descend, but does not drive the mandrel 3 to descend. The oil delivery rod 701 uses hydraulic oil to push the mandrel 3 down. The structure is very ingenious. The occupied space is small, and the lowering of the beam 5 and the lowering of the mandrel 3 will not interfere with each other. As a further improvement, in this embodiment, a bushing 705 is provided on the inner wall of the mandrel 3. The upper end of the mandrel 3 is open and sealed with a sealing cover 706 through a stepped structure, and the sealing cover 706 is fixedly connected to the bushing 705. , the bushing 705 is easy to process, and the mandrel 3 needs a special material as a mold, and the processing difficulty is relatively greater.

Refractory brick mold sticking is a very common problem. During each pressing process, the material powder will be more or less bonded to the surface of the mold. As the number of times of pressing increases, the bonded material powder will accumulate more and more. big. When the bonded material powder accumulates to a certain extent, it will affect the surface quality of the adobe, and then affect the performance of the brick. The process of pressing bricks with a brick press is to turn loose granular powder into a brick with a certain shape and strength. Therefore, the pressing process is actually a process of extrusion between powder and a mold. The sticky mold is the combination of the powder and the mold during the pressing process. In this embodiment, the surface of the mold is treated by TBM (a steel surface hardening process), so that the surface of the mold has a higher hardness. In this way, it is ensured that the mold does not stick to the mold during the pressing process, and the surface quality of the refractory brick is guaranteed.
