Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal casting machines, in particular to a double-layer baffle device of a centrifugal casting machine. Background Art

[0002] Centrifugal casting is an efficient manufacturing technology. Its core is to pour boiling molten metal into a high-speed rotating metal mold. The centrifugal casting machine uses the strong driving force of centrifugal force to cause the molten metal to spread evenly and quickly cool and solidify, finally shaping a precise casting shape. This technology plays an irreplaceable role, especially in the manufacture of rolling mill products, highlighting its unique value in producing high-quality rolling mill rolls. However, the centrifugal force accompanying high-speed rotation may cause the molten metal to overflow, so carefully designed baffle devices are generally installed at the end of the centrifugal casting machine mold. These baffles can effectively control the flow of molten metal during high-speed rotation to avoid overflow, and are the core components to ensure the safe and efficient centrifugal casting process.

[0003] For example, Chinese patent CN219966381U discloses a double-layer baffle device for a centrifugal casting machine, including a mold, a mold box, a protective door, a limiting cylinder, a baffle, a claw mechanism, a first limiting rod and a second limiting rod. The protective door and the baffle form a double-layer protection design, so that the centrifugal casting machine will not cause harm to the workers when rotating at high speed, thereby improving the safety of the workers. However, when performing safety protection, the above-mentioned double-layer baffle device uses the cooperation of the first limiting rod and the torsion spring to ensure that the baffle is close to the front edge of the mold and controls the initial overflow of the molten metal; and as the mold rotates faster, the second limiting rod and the limiting cylinder built into the protective door are delicately engaged to maintain the tight closure of the protective door; but during the casting process, part of the molten metal will inevitably remain inside the baffle device, which not only leads to the waste of raw materials, but also has a certain impact on the efficient use of production resources.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a double-layer baffle device for a centrifugal casting machine to overcome the above technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0008] Furthermore, in order to recover the overflowed molten metal into the centrifugal casting cylinder, the inclined setting of the first inclined portion and the blocking effect of the second inclined portion can enable the overflowed molten metal to flow back into the centrifugal casting cylinder by its own gravity for reuse, thereby avoiding waste and improving the utilization rate of production resources. The reflux plate includes a first inclined portion arranged at one end of the centrifugal casting cylinder, the cross-section of the first inclined portion is a right-angled trapezoidal structure, and the right-angled side of the first inclined portion is located on the side away from the first baffle, and a second inclined portion is arranged at the top of the first inclined portion, and the second inclined portion is inclined toward the first baffle from an end away from the first inclined portion.

[0009] Furthermore, in order to provide safety protection for both ends of the centrifugal casting cylinder, the sealing action of the first sealing part can make it difficult for the molten metal to overflow from the inside of the centrifugal casting cylinder, thereby achieving the purpose of improving the safety of the operation. The second baffle includes a protrusion and a first sealing part which are sequentially arranged on the side of the first baffle close to the reflux plate; the first baffle and the first sealing part are connected by the second sealing part, and the outer side of the second sealing part is close to the inner wall of the centrifugal casting cylinder; a reflux groove is provided on the side of the first sealing part close to the centrifugal casting cylinder, the reflux plate is located inside the reflux groove, and a reflux cavity is formed between the reflux plate and the reflux groove.

[0010] Furthermore, in order to tightly fix the first baffle and the second baffle at the end of the centrifugal casting cylinder, the double-layer baffle device can be fixed at the end of the centrifugal casting cylinder under the cooperation of the snap plate and the snap frame, and under the rotation of the circular nut, the double-layer baffle device and the end of the centrifugal casting cylinder are more closely fitted to ensure the safety protection effect of the double-layer baffle device. The snap locking mechanism includes a plurality of snap plates arranged on the side of the second baffle close to the first baffle and located outside the centrifugal casting cylinder, and a snap frame and a circular nut are sequentially arranged at one end of the snap plate away from the reflux plate; a clamping block is arranged at one end of the snap plate away from the reflux plate, and the cross-section of the clamping block is a triangular structure, and a plurality of snap grooves matching the plurality of clamping blocks are opened on the outer side of the snap frame, and the length of the snap groove is greater than the length of the clamping block.

[0011] Furthermore, in order to make the rubber more suitable for the working environment of centrifugal casting, a ceramic coating can be applied on the surface of the rubber to increase its heat resistance while maintaining the elasticity of the rubber. The reflux plate and the second baffle are both made of rubber material and are coated with a ceramic coating on the surface.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model forms a double-layer protection when the centrifugal casting machine rotates at high speed through the coordinated arrangement of the reflux plate, the first baffle plate, the second baffle plate and the buckle locking mechanism, thereby preventing harm to the staff and improving the safety of the staff. At the same time, the overflowed molten metal is recovered into the centrifugal casting cylinder to avoid waste and improve the utilization rate of production resources.

[0014] 2. By setting up the reflux plate, the overflowed molten metal can flow back into the centrifugal casting cylinder for reuse by its own gravity under the inclined setting of the first inclined part and the blocking effect of the second inclined part, thereby avoiding waste and improving the utilization rate of production resources.

[0015] 3. Through the coordinated arrangement of the first baffle plate and the second baffle plate, the first baffle plate, the first sealing portion and the second sealing portion can make it difficult for the molten metal to overflow from the inside of the centrifugal casting cylinder, thereby achieving the purpose of improving the safety of the operation.

[0016] 4. By setting up a snap locking mechanism, the double-layer baffle device can be fixed to the end of the centrifugal casting cylinder under the cooperation of the snap plate and the snap frame, and under the rotation of the circular nut, the double-layer baffle device and the end of the centrifugal casting cylinder can be more closely fitted, ensuring the safety protection effect of the double-layer baffle device.

[0028] With the aid of the above-mentioned technical scheme of the utility model, the utility model forms a double-layer protection when the centrifugal casting machine rotates at high speed through the coordinated arrangement of the reflux plate 2, the first baffle plate 3, the second baffle plate 4 and the snap-on locking mechanism 5, thereby preventing harm to the staff and improving the safety of the staff.

[0030] In one embodiment, for the above-mentioned second baffle plate 4, the second baffle plate 4 includes a protrusion 401 and a first sealing portion 402 which are sequentially arranged on the side of the first baffle plate 3 close to the reflux plate 2; the first baffle plate 3 and the first sealing portion 402 are connected via the second sealing portion 403, and the outer side of the second sealing portion 403 is in close contact with the inner wall of the centrifugal casting cylinder 1; a reflux groove 40201 is provided on the side of the first sealing portion 402 close to the centrifugal casting cylinder 1, the reflux plate 2 is located inside the reflux groove 40201, and a reflux cavity 40202 is formed between the reflux plate 2 and the reflux groove 40201; under the sealing action of the first sealing portion 402, it is difficult for the molten metal to overflow from the inside of the centrifugal casting cylinder 1, thereby achieving the purpose of improving the safety of the operation.

[0031] The working principle of the reflux plate 2 and the second baffle plate 4: when the centrifugal casting cylinder 1 is performing centrifugal casting, part of the molten metal in the centrifugal casting cylinder 1 will overflow from the gap between the first baffle plate 3 and the inner wall of the centrifugal casting cylinder 1, and flow into the reflux cavity 40202 through the second sealing portion 403, and then, under the inclined setting of the first inclined portion 201 and the blocking effect of the second inclined portion 202, the molten metal in the reflux cavity 40202 can utilize the slope and its own gravity to flow back into the centrifugal casting cylinder 1 from the second sealing portion 403 and the first baffle plate 3 for reuse, thereby avoiding waste and improving the utilization rate of production resources.

[0033] In addition, in specific applications, the above-mentioned snap plate 501 is a metal sheet with an elastic structure, so that the toughness and resilience of the metal material can be utilized to make the snap block 50101 snap into the snap groove 50102.

[0034] Working principle of the snap-locking mechanism 5: When the required molten metal is introduced into the centrifugal casting cylinder 1, the staff moves the snap plate 501 toward the snap frame 502, so that the snap frame 502 squeezes the snap plate 501, and the snap plate 501 bends downward until the clamping block 50101 is clamped into the clamping groove 50102, and under the elastic action of the snap plate 501, the clamping block 50101 is clamped in the clamping groove 50102, thereby driving the first baffle plate 3 to enter the interior of the centrifugal casting cylinder 1, and the reflux plate 2 enters the reflux groove 40201, and then by rotating the circular nut 503, the first baffle plate 3 and the second baffle plate 4 are further driven to move toward the inside of the centrifugal casting cylinder 1, and finally the contact surface of the reflux groove 40201 and the reflux plate 2 is more closely fitted, ensuring the safety protection effect of the double-layer baffle device. When the casting is completed, the circular nut 503 is rotated in the opposite direction to make the snap plate 501 bend downward, so that the block 50101 is no longer stuck in the snap groove 50102, so that the first baffle plate 3 and the second baffle plate 4 can be removed from the end of the centrifugal casting cylinder 1.

[0035] In one embodiment, for the above-mentioned reflux plate 2 and the second baffle plate 4, the reflux plate 2 and the second baffle plate 4 are both made of rubber material and the surface is coated with a ceramic coating; the ceramic coating can be coated on the surface of the rubber to increase its heat resistance and maintain the elasticity of the rubber, making the rubber more suitable for the working environment of centrifugal casting.

[0036] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

During the centrifugal casting process, primary protection is performed by the first baffle 3, and secondary protection is performed by the reflux plate 2 and the second baffle 4. The overflowed metal liquid can flow back into the centrifugal casting cylinder 1 by its own gravity for reuse, and finally the double-layer baffle device is removed from the end of the centrifugal casting cylinder 1 by the snap-on locking mechanism 5 again.
