Description

Technical Field

[0001] The invention belongs to the field of powder metallurgy manufacturing, and in particular relates to an air-cooling device for a powder metallurgy disk. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then manufactures metal materials, composite materials, and various types of parts through sintering or hot isostatic pressing. The general powder metallurgy process includes steps such as powder making, powder processing, densification, and heat treatment. Among them, air cooling during the heat treatment process is a key process in the preparation of powder metallurgy disks, which directly determines the microstructure and properties of the disks. However, due to the large size of the disks and the high degree of uniform cooling required, the microstructure and properties of the cooling process are difficult to stably control. Generally, only a simple fan and turntable can be used to air cool one disk at a time, which is inefficient and the microstructure and properties of the disks often vary greatly.

[0003] In addition, powder metallurgy disks are often designed with holes in the core and other parts according to functional requirements. In existing air cooling technology, when the disk is cooled as a whole, the inner walls of the disk holes are often difficult to handle. There is a problem that the cold air cannot fully pass through the holes, resulting in untimely cooling of the inner walls of the disk holes and failure to cool synchronously with the disk surface, resulting in insufficient cooling of the inner walls of the disk holes, causing structural defects in the disk, and affecting performance and quality.

The base frame 52 is slidably connected to the slide rail 51, and the base frame 52 passes through the inner air storage cylinder 2. Nine disk racks 53 are connected to the top of the base frame 52. Each group of disk racks is composed of 4 square vertical poles evenly distributed with a spacing of 200mm. The material is FGH96. A disk 54 is placed on each of the 9 disk racks 53. The disk material is FGH96, the disk diameter is Φ630mm, the thickness is 340mm, and the weight is 230kg. Each disk 54 is provided with 6 circular holes, the diameter of a central hole is Φ150mm, and the diameter of the 5 circular holes evenly distributed around it is Φ60mm. The rotating air outlet assembly is arranged on the outer air storage cylinder 1, and the shaking assembly is arranged on the rotating air outlet assembly.

[0029] The rotating air outlet assembly includes a motor 61, a drive shaft 62, a large gear 63, a gear ring 64 and a transmission rod 65. The motor 61 is connected to the lower side of the outer wall of the outer air storage cylinder 1 by bolts, and the drive shaft 62 is fixedly connected to the output shaft of the motor 61. The drive shaft 62 is arranged horizontally. The large gear 63 is connected to the drive shaft 62. The large gear 63 passes through the outer air storage cylinder 1. The gear ring 64 is connected to the first air outlet ring 3 by bolts. The large gear 63 is engaged with the gear ring 64.

[0030] The rocking assembly includes a driving bevel gear 71, a fixed rod 72, a passive bevel gear 73, a rocker arm 74, a connecting rod 75 and a cross bar 76. The driving bevel gear 71 is connected to one end of the drive shaft 62, the fixed rod 72 is connected to one side of the outer wall of the outer air storage cylinder 1 by bolts, the passive bevel gear 73 is connected to one end of the fixed rod 72, the rocker arm 74 is welded to the passive bevel gear 73, the connecting rod 75 is connected to the other end of the rocker arm 74, and the cross bar 76 is fixedly connected to one side of the base frame 52. The cross bar 76 is horizontally arranged and connected to the connecting rod 75.

[0031] Initially, each tray rack 53 is loaded with heated trays 54. In actual operation, the operator starts the motor 61 and the blower 4, and adjusts the air volume of the blower 4 to 135m 3 / min, the blower 4 will transport the cold air between the outer air storage cylinder 1 and the inner air storage cylinder 2, and then blow it out from the 7 air outlet nozzles on the 4 air outlet rings 3, and cool the 9 disks 54 in the inner air storage cylinder 2 at the same time. The rotation of the output shaft of the motor 61 will drive the drive shaft 62 to rotate, and the rotation of the drive shaft 62 will drive the large gear 63 and the active bevel gear 71 to rotate together. The rotation of the large gear 63 will drive the gear ring 64 and the 3 transmission rods 65 to rotate together. The rotation of the transmission rod 65 will drive the 4 air outlet rings 3 to rotate. The rotation of the 4 air outlet rings 3 will blow the cold air evenly onto the 9 disks 54, and fully cool the disks 54. The rotation of the active bevel gear 71 will drive the passive bevel gear 73 to rotate. The rotation of the movable bevel gear 73 will drive the rocker arm 74 to rotate. The rotation of the rocker arm 74 will drive the cross bar 76 and the base frame 52 to move back and forth left and right along the slide rail 51 through the connecting rod 75. The left and right reciprocating movement of the base frame 52 will drive the 9 disk racks 53 and the disks 54 to move back and forth left and right. By adjusting the power of the motor 61, the reciprocating movement speed is controlled at about 20 mm / s. The left and right reciprocating movement of the 9 disks 54 will be in more sufficient contact with the cold air blown out by the air outlet ring 3, so that the disk 54 as a whole can be cooled more fully and evenly, the cooling speed can be accelerated, and the cooling efficiency can be improved. When the disk 54 has been cooled, the staff turns off the blower 4 and the motor 61, and removes the disk 54 from the disk rack 53.

[0032] The powder metallurgy disk air cooling and temperature reduction device of the present invention also includes a swinging assembly, which is arranged on the inner air storage cylinder 2. The swinging assembly includes a support frame 81, a limiting rod 82, a rocker arm 84 and a torsion spring 85. The support frame 81 is connected to the inner wall of the inner air storage cylinder 2 by bolts. Three limiting rods 82 are connected to the top of each support frame 81 by bolts. A rocker arm 84 is fixedly connected to each of the disk frames 53. A torsion spring 85 is connected between each of the rocker arms 84 and the top of the base frame 52. The torsion spring 85 is sleeved on the disk frame 53.

[0033] The disk frame 53 moves back and forth, which drives the rocker arm 84 to move back and forth. When the rocker arm 84 moves back and forth, it will continuously contact the limit rod 82 and be squeezed by the limit rod 82, causing the rocker arm 84 to swing, and the torsion spring 85 will be twisted. The swing of the rocker arm 84 will drive the disk frame 53 and the disk 54 to swing together. The rocker arm 84 continues to move and will disengage from the limit rod 82. The reset of the torsion spring 85 will drive the rocker arm 84 to reset. The reset of the rocker arm 84 will drive the disk frame 53 and the disk 54 to reset together. This is repeated, so that the disk 54 can swing back and forth while moving back and forth, so that the cold air blown out by the air outlet ring 3 can be fully blown into the 6 circular holes of the disk 54, and the inner wall of the circular hole is fully cooled, so that the inner wall and surface of the circular hole of the disk 54 can be cooled synchronously, so as to avoid insufficient cooling of the inner wall of the circular hole of the disk 54, resulting in tissue defects in the disk 54, affecting performance and quality.

[0034] The powder metallurgy disk air cooling device of the present invention also includes a disk rotating assembly, which is arranged on a support frame 81. The disk rotating assembly includes a wedge block 91, a roller 92, an overrunning clutch 93, a pinion 94, a vertical rail 95, a rack 96 and a buffer spring 97. Nine wedge blocks 91 are connected to the support frame 81 by bolts. Two rollers 92 are connected to each disk frame 53, and the material thereof is also FGH96. The rollers 92 located on the same disk frame 53 are a group. The disk 54 is located between the two rollers 92, and each roller 92 is in contact with the disk 54. An overrunning clutch 93 is fixedly connected to one side of each roller 92, and a pinion 94 is fixedly connected to the outside of each overrunning clutch 93. Nine vertical rails 95 are connected to the top of the base frame 52 by bolts, and each vertical rail 95 is slidably connected to a rack 96. The rack 96 is in contact with the wedge block 91, and the rack 96 is engaged with the pinion 94. A buffer spring 97 is connected between the vertical rail 95 and the rack 96.

[0035] Initially, since the wedge block 91 is against the rack 96, the buffer spring 97 is in a stretched state, and the reciprocating movement of the base frame 52 will drive the vertical rail 95 and the rack 96 to move back and forth together. When the rack 96 moves, it will no longer be squeezed by the wedge block 91. The reset of the buffer spring 97 will drive the rack 96 to move downward. The downward movement of the rack 96 will drive the pinion 94 to rotate. The rotation of the pinion 94 will drive the overrunning clutch 93 and one of the rollers 92 to rotate. The rotation of one of the rollers 92 will drive the disk 54 to rotate through friction. When the rack 96 is reset, It will continue to be squeezed by the wedge block 91 and move upward, the buffer spring 97 is stretched, and the rack 96 moves upward to drive the pinion 94 to rotate. At this time, the overrunning clutch 93 does not rotate. This is repeated, thereby causing the disk 54 to rotate intermittently. Similarly, the six circular holes on the disk 54 can be more evenly and fully in contact with the cold air, so that the inner wall of the circular hole on the disk 54 can be cooled more evenly, the cooling rate of the inner wall of the circular hole of the disk 54 is accelerated, and the cooling rate of the inner wall and surface of the circular hole on the disk 54 is consistent to a great extent, thereby improving the cooling quality.

[0036] The powder metallurgy disk air cooling device of the present invention also includes a guide frame 10, two guide frames 10 are connected to the base frame 52 by bolts, and 12 air guide plates 11 are connected to the guide frames 10 by bolts. The air guide plates 11 are made of stainless steel plates (thickness of about 3 mm, Ra≤3.2 um), and the angle between them and the horizontal plane is adjusted to 55°~65°, and in this embodiment it is adjusted to 60°.

[0037] The reciprocating movement of the base frame 52 will drive the guide frame 10 and the air guide plate 11 to move back and forth together. The 12 air guide plates 11 will guide the cold air blown out by the air outlet ring 3, so that the cold air can more fully reach the surface of the disk 54 and the inside of the 6 circular holes, thereby quickly and evenly cooling the disk 54.

[0038] In another embodiment, Figure 5 As shown, the powder metallurgy disk air cooling device of the present invention also includes rolling balls 12. Each disk rack 53 is connected to 20 rolling balls 12, and each square column of the disk rack has 5 rolling balls 12. The diameter of the rolling balls is about Φ50mm and the material is FGH96.

[0039] The rolling ball 12 can reduce the friction between the disk 54 and the disk frame 53, so that the disk 54 can rotate more smoothly.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
