Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a double-station guide wheel quenching device. Background Art

[0002] Electromagnetic induction heating, or induction heating for short, is a method of heating conductive materials such as metals. It is mainly used for metal heat processing, heat treatment, welding and melting.

[0003] As the name implies, induction heating uses electromagnetic induction to generate current inside the heated material, relying on the energy of these eddy currents to achieve the purpose of heating. The basic components of the induction heating system include an induction coil, an AC power supply, and a workpiece. Depending on the heating object, the coil can be made into different shapes. The coil is connected to a power supply, which provides an alternating current to the coil. The alternating current flowing through the coil generates an alternating magnetic field passing through the workpiece, which causes the workpiece to generate eddy currents for heating.

[0004] The guide wheel is also called the guide wheel, which is used to guide the crawler to rotate correctly to prevent the crawler from running off the track. In addition, the guide wheel tightens the crawler through the tensioner and buffers the impact of external loads on the whole machine.

[0005] The existing invention patent with publication number CN 116516124 B and publication date 2023.09.08 discloses an induction quenching device for a guide wheel of a hydraulic excavator, including a support seat, a cooling mechanism is arranged in the middle of the top of the support seat, a positioning mechanism is arranged at the top of the cooling mechanism, and a purification mechanism is arranged at the top of the protective cover;

[0006] The cooling mechanism on the support seat of the invention cooperates with the purification mechanism on the protective cover, the transmission gear meshed with the first rack meshes with the second rack on the circular protective cover, the movable column connected to the placement table is connected to the first electric hydraulic cylinder, a partition plate is provided between the partition plate and the purification box, and the air guide hopper connected to the purification box is connected to the exhaust fan, so that the induction quenching device has a protective function. When the guide wheel descends for cooling, the circular protective cover rises and the air inside the protective cover is extracted at the same time, which can block the splashing quenching oil, avoid pollution to the equipment, save resources, and extract and purify the oil smoke generated during quenching to avoid pollution to the environment, making the equipment safer to use.

[0007] However, this technical solution also has a problem: during the entire guide wheel quenching process, single-station operation is adopted. When single-station operation is used, the staff places the guide wheel on the placement table and heats and quenches it through the high-frequency processing machine. During this time, the staff is in an idle waiting state and needs to wait for a period of time after heating and quenching before proceeding to the next step. Therefore, such a single-station quenching method will reduce the work efficiency per unit time.

[0008] Therefore, the utility model proposes a double-station guide wheel quenching device, which is used to improve the quenching efficiency of the guide wheel per unit time. Utility Model Content

[0009] In view of the above technical problems, the utility model provides a double-station guide wheel quenching device, which is used to solve the problem that the existing guide wheel quenching device adopts single-station quenching, resulting in low quenching efficiency per unit time.

[0010] The above technical objectives of the utility model are achieved through the following technical solutions:

[0011] A double-station guide wheel quenching device comprises a quenching box, on which a lifting unit and a heating unit are arranged, characterized in that two lifting units are symmetrically arranged at both ends of the quenching box, the two lifting units act alternately, the heating unit is located between the two lifting units, and the heating unit alternately heats the guide wheels on the two lifting units;

[0014] Furthermore, a reduction motor is provided on the top of the lifting frame, and the output end of the reduction motor is located in the lifting frame and is provided with a first transmission shaft, the end of the first transmission shaft away from the reduction motor is meshed with a second transmission shaft, the end of the second transmission shaft away from the first transmission shaft is meshed with a third transmission shaft, and the third transmission shaft is connected to the lifting plate.

[0015] Furthermore, at least one first support bearing is provided on the first transmission shaft, and at least one second support bearing is provided on the second transmission shaft, and the outer circles of the first support bearing and the second support bearing are both connected to the inner wall of the lifting frame.

[0021] In summary, the beneficial technical effects of the utility model are:

[0022] (1) The driving cylinder is used to drive the turntable to rotate, so that the electromagnetic induction heating device installed on the turntable swings back and forth between the two brackets and heats the guide wheel on the lifting plate. At the same time, the entire lifting machine is lifted and lowered along the first slide rail by the lifting motor using a lead screw. When one of the lifting racks places the guide wheel in the quenching box for cooling, the staff can place a new guide wheel on the other lifting rack and heat it. In this way, the waiting time for quenching is fully utilized, alternating operation is realized, and the quenching efficiency of the guide wheel per unit time is improved.

[0023] (2) The reduction motor is used to drive the lifting plate to rotate through the first transmission shaft, the second transmission shaft and the third transmission shaft, so that the guide wheel placed on the lifting plate can rotate at a uniform speed during heating, thereby making the guide wheel heated more evenly, further improving the quenching quality and shortening the heating time.

[0024] (3) By utilizing the hollow and L-shaped structure of the lifting frame, the weight of the entire lifting frame is reduced while ensuring that the lifting frame has sufficient strength, thereby reducing the workload of the lifting motor.
