Description
Technical Field
The invention relates to the technical field of magnesia carbon brick manufacturing, in particular to magnesia carbon brick forming equipment.
Background
The friction brick press has the advantages of simple structure, low manufacturing cost, easy operation, convenient maintenance and better quality of pressed bricks, and can be widely applied to ceramic factories and refractory factories. Magnesia carbon bricks are used as a refractory product, which is produced by press forming using friction brick presses.
The working principle of the friction brick press is as follows: two friction discs are arranged on the transverse shaft, and the two friction discs are identical in steering direction and rotation speed. A flywheel (friction wheel) is arranged between the two friction plates and is horizontally arranged at the top end of the screw rod. When the screw system operates the cross shaft to move, the situation that neither friction disc is in contact with the flywheel or only one disc is in contact with the flywheel occurs. The flywheel does not rotate; the latter, when the left friction disc presses against the flywheel, the flywheel rotates anticlockwise; when the right friction disk is pressed against the flywheel, the flywheel rotates clockwise. Because the flywheel turns differently, the direction in which the flywheel drives the lead screw to move in the large nut is also different. The lower part of the screw rod is provided with a sliding block and a punch, and the punch moves upwards to finish the work of ejecting products and feeding; when the punch moves downward, the pressing work is completed.
Phenolic resin is used as a bonding agent in the production process of the magnesia carbon brick, raw materials and the bonding agent are put into a die, and the raw materials in the die are stamped by a punch of a friction brick press to finish pressing.
However, in the production process, because the raw materials of the magnesia carbon bricks are loosely filled in the mould, a large amount of air is contained in the raw materials, when the punch presses the raw materials in the mould, the inside of the mould becomes a closed space temporarily after the punch enters the mould because the punch is tightly attached to the inner wall of the mould, the inside of the mould becomes a closed high-pressure ring shape in the pressurizing process of the punch on the raw materials, a large amount of heat is generated under the action of high pressure in the air in the mould, when the punch is pulled out from the inside of the mould after the brick body is molded, the high-pressure air in the brick body is rapidly expanded under the action of self air pressure, the phenolic resin serving as a bonding agent is heated again to cause the temporary strength of the brick body to be reduced, and the rapidly expanded high-pressure air possibly causes the cracking phenomenon of the brick body.

When the cylinder 9 moves down to contact with the brick die 2, the lower end surface of the cylinder 9 covers the upper end surface of the brick die 2 while stopping the downward movement, and the plunger 10 continues to move down to the inside of the brick die 2 under the action of the screw rod 6, at this time, the first air gap 102 is communicated with the second air gap 201. The plunger 10 moves downwards and the cylinder 9 stops moving, so that the plunger 10 can slide downwards in the cylinder 9, the pressure in the cylinder 9 is reduced, and under the action of the pressure after the pressure in the cylinder 9 is reduced, air in the brick die 2 enters the cylinder 9 through the first air gap 102 and the second air gap 201, and the air in the raw material is also pumped into the cylinder 9, so that cracking of the brick after being formed is prevented.
The plunger 10 continues to move downwards and the pressing plate 101 at the bottom of the plunger presses and forms the raw materials in the brick die 2.
The bottom of the second air gap 201 has a height greater than the thickness of the brick after molding to prevent the change of the shape of the brick.

When the cylinder 9 moves up to the same height as the first permanent magnet 15 and the second permanent magnet 301, the first permanent magnet 15 is acted by the magnetic force of the second permanent magnet 301, the clamping hook 14 deflects under the action of the magnetic force, the clamping hook 14 is separated from the clamping block 16 after being deflected, the brick mold 2 is separated from the cylinder 9 after the clamping hook 14 is separated from the clamping block 16, and the brick mold 2 slides down along the guide post 3 and resets under the action of gravity.
Example 3
As shown in fig. 3-8, through holes 103 are formed on two sides of the plunger 10, a scraping plate 19 is slidably matched in the through holes 103 to clean the second air gap 201, a driving structure is arranged in the plunger 10 to drive the scraping plate 19 to slide in the through holes 103, the driving structure comprises a rotating shaft 17, the rotating shaft 17 is rotatably arranged in the plunger 10, one end of the rotating shaft 17 is fixedly connected with the through axis of the connecting shaft 7, the other end of the rotating shaft is fixedly connected with a driving wheel 18, a rack 20 is fixedly connected on the scraping plate 19, the driving wheel 18 is matched with the rack 20, and a limiting block 21 is fixedly connected in the plunger 10 to limit the scraping plate 19.

In the process of moving down the cylinder 9, the hooks 14 synchronously move down, and when the hooks 14 move down to the lowest point, the hooks 14 are clamped on the clamping blocks 16, so that the brick body mold 2 and the cylinder 9 are connected together.
The plunger 10 is driven by the screw rod 6 to move down into the brick mold 2, and the first air gap 102 is communicated with the second air gap 201. The plunger 10 moves downwards and the cylinder 9 stops moving, so that the plunger 10 can slide downwards in the cylinder 9, the pressure in the cylinder 9 is reduced, and under the action of the pressure after the pressure in the cylinder 9 is reduced, air in the brick die 2 enters the cylinder 9 through the first air gap 102 and the second air gap 201, and the air in the raw material is also pumped into the cylinder 9, so that cracking of the brick after being formed is prevented.
