Description

Technical Field

[0001] This utility model belongs to the technical field of quenching equipment, specifically relating to a quenching equipment for steel ball production. Background Technology

[0002] During the steel ball processing, the steel balls need to be quenched. The steel balls are placed in a heating furnace for carburizing treatment, which forms a carbide layer on the surface of the steel balls. Then, the steel balls are placed in a tempering furnace for tempering to eliminate the brittleness of the carbide layer and improve the strength and toughness of the steel balls. Finally, the steel balls are placed in a quenching pool to reduce the temperature of the steel balls, thus completing the quenching process.

[0003] A search revealed that Chinese patent application number "202421303906.6" discloses "a steel ball cooling and quenching device," which describes "a frame and a quenching tank fixed on the frame, further comprising: a loading plate, the loading plate being located directly above the quenching tank and having multiple linearly arranged loading slots on the loading plate, with liquid permeation holes in the loading slots; and a driving mechanism, the driving mechanism being drivably connected to the loading plate for driving the loading plate to move vertically." When using this quenching device, operators must first place the tempered high-temperature steel balls into the loading slots of the loading plate, and then remove the steel balls one by one after quenching. This method is not only time-consuming and labor-intensive, but also affects the efficiency of quenching steel balls in batches. Based on this, we propose a quenching device that can improve the efficiency of steel ball quenching. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides the following technical solution: a quenching equipment for steel ball production, comprising a quenching pool 1 for holding quenching liquid, a first support 2 installed on the top of the quenching pool 1, a quenching frame 3 arranged inside the quenching pool 1, liquid permeation holes 4 opened on the surface of the quenching frame 3, a second support 5 installed on the top of the quenching frame 3, the second support 5 being arranged inside the first support 2, a first electric push rod 6 installed on the top of the first support 2, the piston rod of the first electric push rod 6 extending to the bottom of the first support 2 and fixedly connected to the top of the second support 5, the quenching frame 3 being boat-shaped and having a through-hole at one end. The opening 7 is provided at the bottom of the quenching frame 3, and the opening 7 is located at the low position of the wedge-shaped slope 8. The top of one end of the quenching frame 3 is provided with a slot 9 that passes through the opening 7. A U-shaped bracket 10 is fixedly installed at the top of one end of the quenching frame 3 at the slot 9. A baffle 11 is inserted in the slot 9. A second electric push rod 12 is fixedly connected to the top of the U-shaped bracket 10. The piston rod of the second electric push rod 12 extends to the bottom of the U-shaped bracket 10 and is fixedly connected to the top of the baffle 11. A receiving frame 13 is installed at the top of one end of the quenching pool 1 at the U-shaped bracket 10.

[0022] In this embodiment, the inner wall of the leg of the first bracket 2 is provided with a guide groove 14, and the surface of the leg of the second bracket 5 is fixedly installed with a guide rod 15, which is slidably installed in the guide groove 14.

[0023] Specifically, the guide groove 14, in conjunction with the guide rod 15, effectively improves the stability of the quenching frame 3 during lifting and lowering.

[0024] In this embodiment, the receiving frame 13 is arranged diagonally downwards.

[0025] Specifically, the staff places a collection device at the bottom of the receiving frame 13. When the quenching frame 3 is lifted, the second electric push rod 12 drives the baffle 11 to rise, thereby opening the opening 7. Under the action of the wedge-shaped slope 8, the quenched steel balls will pass through the opening 7 and be guided into the collection device by the receiving frame 13. Therefore, the staff does not need to pick up the quenched steel balls one by one, which reduces the labor intensity of the staff and improves the quenching efficiency of the steel balls.

[0026] In this embodiment, a limit switch is fixedly installed on the top and bottom of the first bracket 2. When the second bracket 5 abuts against the limit switch, the bottom of the opening 7 of the quenching frame 3 is aligned with the receiving frame 13. When the piston rod of the first electric push rod 6 is at its maximum stroke, the bottom of the quenching frame 3 is in contact with the bottom of the quenching pool 1.

[0027] Specifically, the lifting height of the second bracket 5 can be limited by the limit switch. When the second bracket 5 touches the limit switch, the controller controls the first electric push rod 6 to stop working. At this time, the bottom of the opening 7 of the quenching frame 3 is aligned with the receiving frame 13. Therefore, the steel ball can smoothly roll onto the receiving frame 13 through the opening 7, avoiding the steel ball from damaging the receiving frame 13 due to the drop between the bottom of the opening 7 and the receiving frame 13.

[0028] In this embodiment, when the piston rod of the second electric push rod 12 is at its minimum stroke, the bottom of the baffle 11 is flush with the bottom of the slot 9, and when the piston rod of the second electric push rod 12 is at its maximum stroke, the bottom end of the baffle 11 is in close contact with the bottom of the opening 7.

[0029] Specifically, since the bottom of the baffle 11 is flush with the bottom of the slot 9 when the piston rod of the second electric push rod 12 is at its minimum stroke, the lifting stability of the baffle 11 can be improved by setting the slot 9.

[0030] In this embodiment, a drain pipe 16 is installed at one end of the quenching pool 1, and a valve 17 is installed on the surface of the drain pipe 16.

[0031] Specifically, by opening valve 17, the waste quenching liquid can be discharged from quenching pool 1 through drain pipe 16.

[0032] In this embodiment, the first electric push rod 6 is electrically connected to an external power supply through an external controller, and the second electric push rod 12 and the limit switch are both electrically connected to an external power supply through an external controller. The controller can be a PLC controller.

[0033] Working principle: The steel balls to be quenched are transported to the quenching tank 1 and poured into the quenching frame 3 using a special handling device. The steel balls are quenched by the quenching liquid. After quenching, the controller controls the first electric push rod 6 to work, which in turn drives the second support 5 to rise, thereby lifting the quenching frame 3 from the quenching tank 1. When the second support 5 touches the limit switch, the controller controls the first electric push rod 6 to stop working. At this time, the bottom of the opening 7 is aligned with the receiving frame 13. The operator controls the second electric push rod 12 to lift the baffle 11, which opens the opening 7. Under the action of the wedge-shaped slope 8, the quenched steel balls roll through the opening 7 onto the receiving frame 13. The operator has placed a collection device at the bottom of the receiving frame 13 beforehand. The quenched steel balls can then roll into the collection device on their own, eliminating the need for the operator to take out the quenched steel balls one by one. This not only effectively reduces the labor intensity of the operator but also improves the quenching efficiency of the steel balls.

[0034] It should be noted that the first electric push rod 6, the second electric push rod 12, and the limit switch are all commercially available conventional equipment. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art. They will not be described in detail here. The circuit connection involved in this utility model is a common method used by those skilled in the art. Technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
