The forming device of the alumina bubble brick according to claim 4, wherein: the contact surfaces of the first stop dog and the centrifugal hammer sleeve are all arranged to be inclined planes, and the radial direction of the cutter head is located on the inclined planes, so that the centrifugal hammer sleeve impacts the first stop dog along the tangential direction of the cutter head.
6. The forming device of the alumina bubble brick according to claim 2, wherein: the unlocking guide groove is fan-shaped, the width of the groove bottom is smaller than that of the groove opening, the elastic arm is located in the unlocking guide groove at the initial position, a preset included angle is arranged between the outer side face of the elastic arm and the outer side wall of the unlocking guide groove, and the preset included angle is configured to enable the elastic arm to move in the unlocking guide groove 307 along with the centrifugal hammer sleeve and rotate for a preset angle to enter the limiting groove.
7. The forming device of the alumina bubble brick according to claim 4, wherein: through holes for the mounting columns to pass through are formed in the first stop block and the second stop block, and two ends of each mounting column respectively pass through the through holes of the first stop block and the second stop block; the first stop dog is connected with one end of the mounting column through the positioning pin, and the second stop dog is fixedly connected with the other end of the mounting column through the nut.
8. The forming equipment of the alumina bubble brick according to claim 1, wherein: the centrifugal hammer subassembly has a plurality ofly, along blade disc circumference evenly distributed.
9. The forming equipment of the alumina bubble brick according to claim 1, wherein: the energy storage spring is sleeved with a protective corrugated pipe which contracts and expands synchronously with the energy storage spring so as to prevent raw materials from entering the energy storage spring.
10. A forming process of an alumina bubble brick is characterized in that: an apparatus for forming alumina bubble brick according to any one of claims 1 to 9, comprising: adding the raw materials into a grinding mill, starting a motor, and driving a cutter head to rotate by the motor; the centrifugal hammer enables the centrifugal hammer sleeve to extrude the energy storage spring due to self inertia under the acceleration action of the starting of the cutter head, so that the energy storage spring stores energy, the centrifugal hammer and the centrifugal hammer sleeve rotate around the axis of the cutter head, the centrifugal hammer swings outwards under the centrifugal action of rotation, so that the elastic buckle is clamped in one limiting groove, and is continuously clamped in the next limiting groove when the centrifugal hammer sleeve moves backwards relative to the mounting column to continuously extrude the spring until the energy storage spring is compressed to the maximum deformation position; when the cutter head is locked and stops rotating, the centrifugal hammer swings back downwards under the action of self weight to separate the elastic buckle from the limiting groove, so that the centrifugal hammer sleeve impacts the cutter head under the action of the energy storage spring to release the locking of the cutter head, the cutter head continues to rotate under the action of the motor, the centrifugal hammer sleeve is accelerated to rotate at first to extrude the energy storage spring again, and the elastic buckle is clamped in one limiting groove again along with the swinging of the centrifugal hammer sleeve; the planetary stirrer receives the raw materials ground by the grinding machine to stir and mix; the upper pressing die assembly receives the blank stirred by the planetary stirrer and interacts with the brick discharging groove to form the blank.
