Description

Technical Field

[0001] The utility model relates to the field related to chain bearing quenching, and in particular to a chain type bearing continuous quenching device. Background Art

[0002] Chain bearing quenching is a heat treatment process used to improve the hardness and wear resistance of chain bearings. This process can change the structure of the chain bearing, thereby changing its physical properties, increasing its hardness and strength, making it more wear-resistant and durable.

[0003] The traditional bearing quenching process usually adopts intermittent operation. The traditional bearing quenching process requires intermittent heating and quenching, which has low production efficiency. Intermittent operation is prone to fluctuations in the bearing quenching temperature, thereby affecting the stability and consistency of the quenching quality. In addition, intermittent operation requires manual operation, which is labor-intensive. Therefore, we have made improvements to this and proposed a chain-type bearing quenching continuous device.

[0033] In this embodiment: the first rotating shaft 301 and the second rotating shaft 302 are both rotationally connected through the chain body 304 on the surface of the sprocket 303. When the first rotating shaft 301 rotates, it can drive the chain body 304 to move and drive the fixed plate 305 on the surface to follow the movement. In conjunction with the fixing mechanism 4 on the surface, automatic loading of bearings can be achieved.

When the bearing is placed in the induction coil 503 wound by the hollow copper tube, when the induction coil 503 is connected with alternating current, an induced current with the same frequency and opposite direction will be induced inside the bearing. Since the steel itself has resistance, the eddy current is concentrated on the surface of the workpiece, and the surface temperature of the workpiece can be raised to 800-1000°C in a few seconds, and then cooled by the cooling mechanism 6, thereby achieving the purpose of quenching.

[0043] As a preferred embodiment, a second motor 504 is fixedly installed on the top of the box body 1, and a threaded rod 505 is fixedly connected to the output end of the second motor 504, and the connection method between the threaded rod 505 and the connecting plate 501 is a threaded connection, and limiting rods 506 are fixedly installed on both sides of the threaded rod 505 on the top of the box body 1, and the connection method between the two limiting rods 506 and the connecting plate 501 is a sliding connection.

[0045] refer to Figure 1 - Figure 6 Based on the above embodiment, the bearing can be cooled quickly. This embodiment provides the following design:

[0046] As a preferred embodiment, the cooling mechanism 6 includes a water tank 601, and the water tank 601 is arranged at the bottom of the box body 1, and a water pump 602 is fixedly installed inside the water tank 601, a water suction pipe 603 is fixedly installed on one side surface of the water pump 602, and a water supply pipe 604 is fixedly installed on the other side surface of the water pump 602, a fixed pipe 605 is fixedly installed inside the box body 1, and a plurality of nozzles 606 are fixedly installed on the lower side surface of the fixed pipe 605, and the other end of the water supply pipe 604 is connected to the fixed pipe 605.

[0047] In this embodiment: by starting the water pump 602, the water in the water tank 601 is pumped out by the water pump 602, discharged into the fixed pipe 605 through the water pipe 604, and sprayed out from the nozzle 606 at the bottom, so as to realize the rapid cooling of the bearing and achieve the purpose of quenching.

[0048] Specifically, the working principle of this solution is:

[0049] When in use, the first motor 306 is started to drive the first rotating shaft 301 to rotate, and cooperate with the second rotating shaft 302 on the other side, so that the sprocket 303 and the chain body 304 on the surface can make the first rotating shaft 301 and the second rotating shaft 302 rotate synchronously, and the chain body 304 moves synchronously and drives the fixed plate 305 to move. When placing the bearing, the inner ring of the bearing is put on the outside of the two sliding rods 404. The two sliding rods 404 will drive the slider 403 to move and cause the tension spring 405 to deform. At the same time, the sliding rod 404 can be pulled by the tension of the tension spring 405, and the inner ring of the bearing can be supported by the sliding rods 404 on both sides, so as to achieve the purpose of fixing the bearing, and the bearing is automatically loaded by rotating the chain body 304.

[0050] Through the intermittent movement of the first motor 306, when the two bearings on the upper side of a fixed plate 305 move to the lower side of the two induction coils 503, it will stop and start the second motor 504 to drive the threaded rod 505 at the output end to rotate, and the threaded rod 505 drives the connecting plate 501 to move up and down, thereby driving the heater 502 and the induction coil 503 to move, and the induction coil 503 is sleeved on the outside of the bearing, and the induction coil 503 is operated by the heater 502. When the bearing is placed in the induction coil 503 wound by the hollow copper tube, the bearing is heated, and the water pump 602 is started to work. The water pump 602 pumps the water inside the water tank 601 out, discharges it into the fixed pipe 605 through the water pipe 604, and sprays it out from the nozzle 606 at the bottom, so as to realize the rapid cooling of the bearing and achieve the purpose of quenching. The above is the working process of the whole device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
