DETAILED DESCRIPTION

[0017] The specific embodiment of the utility model is further described below in combination with the drawings.

[0018] As Figures 1-5 shown, a high-strength nut quenching device includes a quenching pool 1 for containing quenching liquid, the upper end of the quenching pool 1 is open, the inside of the quenching pool 1 is obliquely provided with a high-temperature-resistant conveying belt 2, the conveying belt 2 is fixed on the quenching pool 1 through a reinforcing plate 3, the upper end of the conveying belt 2 extends to the outside of the quenching pool 1, one side of the quenching pool 1 is provided with a high-frequency heater 4, the high-frequency heater 4 is provided with an induction coil 5, the upper surface of the quenching pool 1 is provided with a fixed plate 6, the fixed plate 6 is provided with an electric push rod 7, the electric push rod 7 is installed on the fixed plate 6 through a snap ring, the output end of the electric push rod 7 is provided with a porcelain rod 8 that can pass through the induction coil 5, the outer surface of the porcelain rod 8 is provided with a porcelain ring 9, one side of the upper surface of the fixed plate 6 is provided with a blanking plate 10, the blanking plate 10 is provided with a through hole 11, the inner diameter of the through hole 11 is greater than the outer diameter of the porcelain ring 9 but less than the outer diameter of the nut 18, and the blanking plate 10 is used to make the nut 18 on the porcelain rod 8 move out of the porcelain rod 8 and fall onto the conveying belt 2 in the quenching pool 1.

[0019] The conveying belt 2 is a stainless steel mesh belt and can work in a high-temperature environment, and is used to convey the nut 18 that has completed quenching in the quenching pool 1 out.

[0020] The porcelain rod 8 and the porcelain ring 9 are integrated structures, which are formed by firing. The porcelain ring 9 is used to limit the number of nuts 18 placed on the porcelain rod 8 and facilitate the quick positioning of the nuts 18 when placed. The end of the porcelain rod 8 close to the porcelain ring 9 has a protrusion with external threads. The output end of the electric push rod 7 has a threaded groove. The porcelain rod 8 can be connected to the electric push rod 7 through the protrusion. The porcelain rod 8 and the porcelain ring 9 are not conductive in a dry state, so the induction coil 5 cannot inductively heat the porcelain rod 8 and the porcelain ring 9. The heat on the porcelain rod 8 and the porcelain ring 9 is transferred by the nuts 18 after induction heating. Therefore, there is a risk of burning hands when the nuts 18 are sleeved on the porcelain rod 8. Anti-burning gloves can be worn for placement operations, and multiple nuts 18 can be sleeved on the porcelain rod 8 at one time to improve the installation efficiency of the nuts 18.

[0021] When quenching the nuts 18, first control the output end of the electric push rod 7 to extend. The electric push rod 7 pushes the porcelain rod 8 to completely pass through the induction coil 5. Then, the nuts 18 are sleeved on the porcelain rod 8. Multiple nuts 18 are neatly stacked on the porcelain rod 8, and one of the nuts 18 abuts against the porcelain ring 9, so as to make full use of the porcelain rod 8. After the placement of the nuts 18 is completed, the electric push rod 7 is started. The electric push rod 7 drives the porcelain rod 8 to enter the induction coil 5. When the nuts 18 on the porcelain rod 8 completely enter the induction coil 5 and the output end of the electric push rod 7 also completely leaves the induction coil 5, the electric push rod 7 stops moving. Then, the high-frequency heater 4 is started. The nuts 18 on the porcelain rod 8 are heated by the induction coil 5. After a certain time of heating, the nuts 18 are heated to a predetermined quenching temperature. The induction coil 5 stops heating the nuts 18. Then, the electric push rod 7 is started. The output end of the electric push rod 7 drives the porcelain rod 8 to move in the direction of the discharge plate 10. The porcelain rod 8 and the porcelain ring 9 can pass through the through hole 11 on the discharge plate 10, while the larger nuts 18 cannot pass through the through hole 11 on the discharge plate 10. Therefore, the nuts 18 on the porcelain rod 8 can all fall into the quenching tank 1 for quenching. The nuts 18 fall onto the conveyor belt 2 in the quenching tank 1. The conveyor belt 2 moves relatively slowly, so that the nuts 18 can be effectively quenched. After the quenching of the nuts 18 is completed, the conveyor belt 2 transfers all the nuts 18 in the quenching tank 1 out.

[0022] The action of the electric push rod 7 is controlled by the corresponding PLC program and triggered by a button, so that the electric push rod 7 performs the predetermined action. When the button is pressed for the first time, the output end of the electric push rod 7 extends a certain length, so that the porcelain rod 8 can completely pass through the induction coil 5, so as to place the nut 18 on the porcelain rod 8; when the second time, the output end of the electric push rod 7 retracts, so that the nut 18 on the porcelain rod 8 can completely enter the induction coil 5, so as to heat all the nuts 18 on the porcelain rod 8. The action of the electric push rod 7 and the high-frequency heater 4 is associated. After the porcelain rod 8 moves to the predetermined position, the high-frequency heater 4 automatically works and starts to heat the nut 18. After a certain time of heating, for example, 5 seconds, the high-frequency heater 4 stops working. When the third time, the output end of the electric push rod 7 continues to retract, and the nut 18 on the porcelain rod 8 falls into the quenching tank 1 through the discharging plate 10. When the output end of the electric push rod 7 retracts to a certain extent, the nut 18 on the porcelain rod 8 has been dropped out. At this time, the button is pressed once, and the output end of the electric push rod 7 performs the extension action, so as to completely pass through the induction coil 5 and continue to place the nut 18 on the porcelain rod 8.

[0023] Further, the outer surface of the conveying belt 2 is provided with vertical plates 12 at intervals. By arranging the vertical plates 12, the nuts 18 on the conveying belt 2 can be prevented from continuously rolling off, so that the nuts 18 can be reliably transferred out of the quenching tank 1.

[0024] Further, the quenching tank 1 is provided with baffles 13 on both sides of the conveying belt 2. The nuts 18 falling from the porcelain rod 8 into the quenching tank 1 are located between the two baffles 13, so as to avoid the collision between the nuts 18 and make some nuts 18 fall from both sides of the conveying belt 2 to the bottom of the quenching tank 1.

[0025] Further, the other side of the quenching tank 1 is provided with a receiving box 14. The bottom of the receiving box 14 is provided with a roller 15, and the side of the receiving box 14 is provided with a handle 16. The receiving box 14 is convenient for receiving the nuts 18 falling from the conveying belt 2, and the handle 16 and the roller 15 are convenient for controlling the movement of the receiving box 14.

[0026] Further, the inside of the receiving box 14 is provided with a separation net 17, and the nuts 18 are located above the separation net 17. The residual quenching liquid on the nuts 18 is collected at the bottom of the receiving box 14 through the separation net 17. When a certain amount of quenching liquid is collected at the bottom of the receiving box 14, the quenching liquid in the receiving box 14 can be re-discharged into the quenching tank 1, so as to reduce the waste of quenching liquid.

[0027] In the description of the utility model, unless another definite provision and limit, term " install " " link " " connection " should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electric connection, can be direct connection, also can indirectly connect through intermediate medium, can be two elements inside the intercommunication. For ordinary skilled person in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
