[0001] The invention relates to the technical field of bearing casting, in particular to copper-steel bimetal composite slip ring bearing manufacturing and processing equipment for a planetary frame of a wind power gear box. Background Art

[0006] Preferably, ventilation grooves are provided on the tops of the arc push block 1 and the arc push block 2, and guide plates are fixedly connected to the upper inner walls of the ventilation grooves of the arc push block 1 and the arc push block 2. The guide plates are divided into an inner circle and an outer circle and are inclined inwardly and outwardly respectively. Gaps are left between the two guide plates and between the guide plates and the inner wall of the arc push block 1 for cold air to pass through. The arc push block 1 and the arc push block 2 are symmetrically arranged on the left and right, and the gaps between the two arc push blocks 2 and between the two arc push blocks 1 are equal to the width of the connecting plate.

[0007] Preferably, the bottom of the arc-shaped push block one and the arc-shaped push block two is fixedly connected with an annular plate two, the bottom of the annular plate two is fixedly connected with an air intake bin, and one side of the air intake bin is fixedly connected with an air intake pipe for connecting to an external compressor to input cold air into the air intake bin.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention sets a push rod motor, a lower mold, an upper mold and a through hole. After the push rod motor is turned on, the annular sheet and the lower mold are pulled down through the fixed plate. When the metal solution is injected into the lower mold, the lower mold and the annular sealing plate move downward synchronously, so that the gap between the annular sealing plate and the upper mold is gradually increased to facilitate the injection of the solution. The speed at which the lower mold and the annular sealing plate move downward is consistent with the injection speed of the metal solution. The air mixed in the solution during injection is discharged through the through hole on one side. Since the opening of the through hole is always located above the liquid surface of the solution, the problem of the solution blocking the discharge port and causing the air to be unable to be discharged is avoided. In addition, the lower mold and the upper mold are fitted together in the initial state to greatly reduce the amount of air inside. In combination with the exhaust during injection, the possibility of the metal solution mixing with bubbles is reduced. This solves the problem that when the traditional slip ring bearing processing equipment is used to inject the metal solution into the mold during casting, the metal solution is mixed with the air in the mold, which easily generates bubbles inside the solution and causes hollowing, resulting in poor quality of the produced slip ring bearing. The present invention provides a lower mold, an arc-shaped push block 1 and an arc-shaped push block 2, and injects cold air into the air inlet bin through an air inlet pipe. The cold air is discharged upward through the ventilation grooves of the arc-shaped push block 1 and the arc-shaped push block 2. When passing through the guide plate, the cold air is guided by the guide plate into three cold air flows inclined inward, vertically upward and inclined outward, which are blown to the inner and outer rings of the lower mold and the hollow interior of the center column and the bottom of the annular sealing plate respectively, so as to cool the lower mold and the annular sealing plate, so that the molten metal is quickly formed, and the cooling area is evenly distributed, so as to improve the cooling effect. Then, the cold air carries the heat and is discharged through the exhaust groove of the lower mold and the exhaust holes on the surface of the upper cover plate, so as to avoid the accumulation of hot air. The present invention provides a lower mold, an annular sealing plate, an arc-shaped push block 1 and an arc-shaped push block 2, starts a push rod motor to continue to pull down the lower mold, so that the arc-shaped push block 1 passes through the gap between the outer ring group, the inner ring group and the center ring and slides into the lower mold, and the annular sealing plate is lifted upward to demould the formed bearing, and at the same time, the lower mold moves downward and is separated from the upper mold, so that the formed bearing can be easily ejected; The present invention arranges a lower mold, an annular sheet 1 and a limiting rod. The annular sheet 1 slides along the limiting rod to avoid angle deviation and improve stability, so that the bottom opening of the lower mold always corresponds to the position of the arc push block 1 and the arc push block 2 to avoid jamming.

[0019] Working principle: in the initial state, the annular sealing plate 8 is located at the lower side of the lower mold 2, the bottom of the annular sealing plate 8 fits the top of the connecting plate 3, and the upper mold 10 is located in the gap between the inner and outer rings, the inner ring and the center column of the lower mold 2. The bottom of the upper mold 10 fits the top of the annular sealing plate 8. After the copper-steel metal is melted, it is injected into the feed bin 27 through the feed baffle 30. The molten metal is guided by the guide block 31 and concentrated to the middle part through the extension pipe 28 to flow into the through hole 29 and the through groove 11, and then discharged onto the annular sealing plate 8.

The cold air is discharged upward through the ventilation grooves of the arc-shaped push block 1 21 and the arc-shaped push block 22. When passing through the guide plate 23, the cold air is guided by the guide plate 23 into three cold air flows inclined inward, vertically upward, and inclined outward, which are blown to the inner and outer rings of the lower mold 2 and the hollow interior of the center column and the bottom of the annular sealing plate 8 respectively, so as to cool the lower mold 2 and the annular sealing plate 8, so that the molten metal is quickly formed, and the cooling area is evenly distributed to improve the cooling effect. Then, the cold air carries the heat through the exhaust groove of the lower mold 2 and the exhaust holes 12 on the surface of the upper cover plate 9 and is discharged; After the metal solution is cooled and formed, the cold air delivery is turned off, and the push rod motor 1 is turned on to continue to pull down the lower mold 2, so that the arc-shaped push block 21 passes through the gap between the outer ring group 4, the inner ring group 5 and the center ring 6 and slides into the lower mold 2, and the annular sealing plate 8 is lifted up to demold the molded bearing. At the same time, the lower mold 2 moves down and separates from the upper mold 10 to facilitate the removal of the molded bearing.
