Description

Technical Field

[0001] The utility model relates to the technical field of quenching, in particular to a quenching device for machining a motor shaft. Background Art

[0002] Quenching is a heat treatment process. Quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept at this temperature for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation. The solution treatment or heat treatment process with rapid cooling process of materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass is usually called quenching.

[0003] The motor shaft quenching equipment generally controls the motor shaft to rise and fall and rotate, and directly heats the part of the motor shaft located inside the coil through the coil. After heating, the coolant is sprayed below it to cool it. Due to the small interval between the cooling and heating distances, the cooling and heating steps will affect each other, resulting in insufficient heating temperature and cooling rate in some parts, which affects the quenching effect of the motor shaft. In view of this, we propose a quenching device for motor shaft processing. Utility Model Content

When the motor shaft located inside is heated by the heating coil 7, the heat insulation plate 8 blocks the cooling of the motor shaft after heating by the heating coil 7 and the cooling tube 13 below. At the same time, the funnel-shaped heat insulation plate 8 with a smooth inner wall isolates the heat and reflects the heat to a certain extent, so that the heat can be repeatedly concentrated near the heating coil 7, and the coolant is prevented from splashing up from under the heat insulation plate 8, thereby improving the heating effect and avoiding the situation where the cooling and heating steps affect each other and reduce the quenching effect. At the same time, when the motor shaft is controlled to rotate and in contact with the outer surface of the wire ring 12, the oxide on the outer surface of the motor shaft during the quenching process is cleaned.

[0024] Specifically, a water tank 5 is provided inside the quenching device 1, and two drain pipes, one high and normally open and the other low and normally closed, are connected on the outer surface of the water tank 5. A filter bucket 101 is provided on the upper surface of the quenching device 1. A receiving plate 102 is fixedly connected to the middle of the filter bucket 101, a support column 103 is fixedly connected to the inner surface of the receiving plate 102, a baffle 107 is fixedly connected to the upper end of the support column 103, a solution box 104 is movably connected to the outer surface of the support column 103, a dissolution box 105 is provided inside the solution box 104, and a cover plate 106 is provided on the upper surface of the solution box 104; the utility model controls the liquid level inside the water tank 5 through the action of the two drain ports of the water tank 5, and the acid-base oxidant solution box 104 filled with the corresponding material of the outer surface of the motor shaft rises under the floating of wastewater, and then the metal oxides gathered inside the receiving plate 102 are immersed and dissolved, so as to facilitate the treatment of the metal oxides generated and cleaned during the quenching process.

[0025] Furthermore, the connecting hole 14 is connected to the water pipe passing through the inside of the quenching device 1, and the cooling pipe 13 is located between the water receiving plate 10 and the insulation plate 8, and the diameter of the lower end of the water receiving plate 10 is smaller than the inner diameter of the water wall 4; the cooling pipe 13 located between the water receiving plate 10 and the insulation plate 8 is convenient for quickly cooling the heated motor shaft and washing the scraped metal oxides, and the lower end of the water receiving plate 10 with a smaller diameter avoids affecting the discharge of waste water.

[0026] Furthermore, the distance between the receiving plate 102 and the drain pipe at the top of the water tank 5 is smaller than the height of the solution box 104, and the baffle 107 and the solution box 104 are movably connected via an axis equipped with a torsion spring; when the water level reaches a position higher than the drain pipe, the baffle 107 on the outer surface of the solution box 104 is opened, and the receiving plate 102 and its upper end portion are immersed in the solution inside the solution box 104 to dissolve the oxide.

[0027] It is worth noting that the bottom diameter of the baffle 107 is larger than the diameter of the receiving plate 102, and a gap is retained between the baffle 107 and the filter bucket 101; the baffle 107 with a larger bottom diameter is convenient for blocking wastewater from splashing to the receiving plate 102, and for treating the accumulated oxides on the receiving plate 102.

[0028] It is worth noting that the interior of the dissolution box 105 is provided with a spherical rubber layer with dense inverted funnel-shaped holes on the surface; the inverted funnel-shaped holes on the outer surface of the rubber layer enable the receiving plate 102 to contact and squeeze the rubber layer inside the dissolution box 105, and the solution will overflow. When the spherical surface is reset, the solution will be lifted up and gathered to the edge.

[0029] It is worth mentioning that an opening is provided on the outer surface of the dissolution box 105, and a water flow groove corresponding to the opening on the outer surface of the dissolution box 105 is provided on the outer surface of the solution box 104, and the water flow groove is not connected to the interior of the solution box 104; the opening on one side of the dissolution box 105 discharges the oxide after infiltration and dissolution from the water flow groove on one side of the solution box 104 through the reset of the rubber layer.

[0030] Working principle: During the quenching process of the motor shaft, the fixed motor shaft rotates and descends under the simultaneous action of the first motor 2 and the second motor 3. When the motor shaft enters the interior of the heating coil 7, it will be heated and turned red under the action of the coil. At this time, the heating heat is blocked by the heat insulation plate 8 and isolated from the coolant sprayed from the cooling pipe 13 below to avoid mutual interference. At the same time, the funnel-shaped smooth inner wall of the heat insulation plate 8 can reflect the heat to a certain extent, thereby improving the heating effect. During the cooling process, the motor shaft will contact the wire ring 12 during rotation, and the oxides on the outer surface of the motor shaft will be cleaned. After cleaning, the oxides will be discharged into the interior of the filter bucket 101 along with the cooling wastewater, and the wastewater will be filtered in the filter bucket 101. At the same time, when the water flows from the side of the filter bucket 101 Under the impact of the edge, the oxides are concentrated on the receiving plate 102. When the waste water inside the water tank 5 gathers to the high drain pipe and water overflows, the solution box 104 moves upward under the action of buoyancy and makes the rubber layer inside the dissolution box 105 squeezed and deformed by the receiving plate 102, and releases the corresponding acid and alkali solution to dissolve the oxides gathered on the surface of the receiving plate 102, and then opens the low drain pipe to release the waste water inside the water tank 5. At the same time, the rubber layer recovers its deformation to push the dissolved oxides out from the surface of the rubber layer and discharge them along the opening of the dissolution box 105 and the water flow trough on one side of the solution box 104, which is convenient for separating the heating and cooling areas during the quenching process of the motor shaft, and at the same time, the surface oxides of the motor shaft are treated during the quenching process, which is convenient for the use of the equipment.
