Description

Technical Field

[0001] The utility model relates to the technical field of bearing rings, in particular to an automatic conveyor for hot forming bearing rings. Background Art

[0002] Bearing rings are an important part of rolling bearings, which usually refer to the inner ring and outer ring. The main function of bearing rings is to provide a rolling path for rolling elements (such as balls or rollers) while bearing the load from the shaft or bearing seat. The performance of bearing rings is directly related to the life and reliability of the entire bearing.

[0003] The material of the bearing ring is usually high carbon chromium bearing steel, such as GCr15 and GCr15Si Mn, which have good hardness, wear resistance and fatigue strength. In the manufacturing process, heat treatment process is a key step to ensure the performance of the bearing ring.

[0004] The hot forming process mainly includes spheroidizing annealing, quenching and tempering. Spheroidizing annealing is a preliminary heat treatment, the purpose of which is to transform the original pearlite structure into spherical pearlite, thereby improving the strength and toughness of the material. Quenching and tempering are final heat treatments, which can improve the hardness and wear resistance of the bearing rings, while obtaining high contact fatigue strength and dimensional stability.

[0005] During the heat treatment of the bearing ring, the bearing ring needs to be transferred. Due to the extremely high melting point of its own material, the temperature of the bearing ring is extremely high after completing one round of heat treatment. If it needs to be transferred, the temperature of the bearing ring needs to be lowered before it can be transferred manually. Otherwise, the high temperature will cause the bearing ring to cause safety problems to the operator. However, it takes a lot of time to heat the bearing ring again after it has been cooled down.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] A bearing ring thermoforming automatic conveyor, such as Figure 1 As shown, it includes a flow channel 2 with an open top surface, a flow guide component, a feed component, and a discharge component;

[0029] The flow channel 2 is filled with a guide liquid, the temperature of the guide liquid is lower than the melting point of the bearing ring, and the density of the guide liquid is higher than the density of the bearing ring. Specifically, the guide liquid is molten lead.

[0030] like Figure 2 As shown, the feed assembly is arranged at one end of the flow channel 2 and is communicated with the top surface of the flow channel 2. The feed assembly includes a feed barrel 3 fixedly connected to one end of the flow channel 2. The feed barrel 3 is arranged vertically, and there is a channel running from top to bottom inside the feed barrel 3. The lower end of the channel is communicated with the inside of the flow channel 2. The feed barrel 3 is a tubular structure, and the cross section of the feed barrel 3 is a square tube.

[0031] like Figure 3As shown, the discharging assembly is arranged at the other end of the flow channel 2 to lift the bearing ring in the flow channel 2 away from the top surface. The discharging assembly includes a plurality of columns 7 vertically fixedly connected to one end of the flow channel 2, a top plate 8 fixedly connected to the top surface of the column 7, a plurality of cylinders 10 vertically fixedly connected to the top plate 8, a connecting rod 11 coaxially fixedly connected to the piston rod in the cylinder 10, a receiving net bucket 12 vertically slidably connected in the flow channel 2, a connecting seat 13 fixedly connected to one side of the flow channel 2, and a mechanical arm 14 fixedly connected to the connecting seat 13, the receiving net bucket 12 is fixedly connected to the lower ends of the plurality of connecting rods 11, one end of the top plate 8 is fixedly connected to a vertically arranged side plate 9, and the side plate 9 is fixedly connected to the side wall of the top column;

[0032] A guide assembly is arranged in the flow channel 2 and is located between the feed assembly and the discharge assembly. It guides the guide liquid to flow in the flow channel 2. The guide assembly includes two upper bearing seats 4 fixedly connected to the top surface of the flow channel 2, an upper rotating shaft 5 fixedly connected to the inner ring of the upper bearing seat 4, an upper sprocket 6 fixedly connected to the upper rotating shaft 5, a lower bearing seat fixedly connected to the inner wall of the flow channel 2, a lower rotating shaft fixedly connected to the inner ring of the lower bearing seat, a lower sprocket fixedly connected to the lower rotating shaft, a chain drivingly connecting the upper sprocket 6 and the lower sprocket, a plurality of guide blades fixedly connected to the lower rotating shaft, a reduction motor arranged on one side of the flow channel 2, and a coupling drivingly connected to the output shaft of the reduction motor. One end of the upper rotating shaft 5 passes through the flow channel 2 to the outside, and the upper rotating shaft 5 at this end is drivingly connected to the coupling.

[0033] When the utility model needs to transfer the bearing ring with a large amount of heat, it only needs to put the bearing ring into the flow channel 2 through the feed barrel 3. The molten lead also has a certain amount of heat, and the molten lead can be used as a guide liquid for carrying without cooling the bearing ring to room temperature. The setting of the feed barrel 3 is to block the splashed molten lead to prevent it from splashing into the surrounding environment. Under the operation of the guide component, the reduction motor drives the upper shaft 5 to rotate, and under the transmission of the upper sprocket 6, the chain, and the lower sprocket, the lower shaft and the guide vanes thereon are driven by the upper sprocket 6, the chain, and the lower sprocket. The sheet also rotates, thereby guiding the flow of the molten lead, so that the bearing ring can flow from one end to the other end. After a certain amount, the receiving net bucket 12 is raised by the cylinder 10 and the connecting rod 11, so that the molten lead is filtered out, and only the bearing ring with a certain amount of heat is retained in the receiving net bucket 12, and then it is taken out by the mechanical arm 14 and put into the next heat treatment link. In this way, the bearing ring can be transferred to the next set of hot forming processes without cooling it to room temperature, which greatly shortens the time required for heating the bearing ring.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
