Description

Technical Field

[0001] The utility model relates to the technical field of metal heat treatment equipment, in particular to a heat treatment device for processing roll castings. Background Art

[0002] After the roll casting is formed, the internal structure of the metal is not yet uniform and stable enough, and the metal properties also fail to meet the expected requirements. Therefore, it is necessary to perform corresponding heat treatment on the casting to improve the metal properties and uniform the internal structure. In the process of heat treating the casting, an essential step is to heat the casting to a certain temperature. The commonly used heating device in the prior art is open flame heating, which requires adjusting the ratio of fuel to oxygen. Moreover, the open flame heating is uneven, and the fuel combustion will also generate some pollutants, which need to be purified before being discharged. The heating process is relatively complex. Content of the Utility Model

[0003] The purpose of the utility model is to provide a heat treatment device for processing roll castings, which can realize rapid and uniform heating of the casting, efficiently heat the casting to the target temperature, and facilitate subsequent heat treatment operations.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A heat treatment device for processing roll castings includes a box body, a lifting mechanism, an electromagnetic induction heater, and a heating coil. A partition is vertically arranged in the box body, which divides the box body into a heating space and an installation space. The electromagnetic induction heater is installed in the installation space, the heating coil is installed at the top of the heating space and is electrically connected to the electromagnetic induction heater, and the lifting mechanism is installed at the bottom of the heating space and directly below the heating coil; A placement plate is arranged at the top of the lifting mechanism, and a casting inlet and a casting outlet corresponding to the placement plate are respectively arranged on the front and rear sides of the box body.

[0005] Optionally, the lifting mechanism includes a lifting cylinder and a support plate. The support plate is fixedly connected between the casting inlet and the casting outlet. A through hole is provided on the support plate, and the top of the lifting cylinder passes through the through hole and is connected to the bottom of the placement plate.

[0006] Optionally, a positioning groove is provided on the support plate, and a positioning block matching the positioning groove is arranged at the bottom of the placement plate.

[0007] Optionally, baffles are fixedly connected to both sides of the support plate.

[0008] Optionally, guide rods are vertically arranged on the support plate, and the placement plate is slidably connected to the guide rods.

[0009] Optionally, a limit plate is arranged at the top of the guide rod.

[0010] The heat treatment device for processing roll castings of the utility model has the following advantages:

[0011] (1) The casting can be placed on the placement plate through the casting inlet. When the lifting mechanism rises, the casting is moved into the heating coil. After the electromagnetic induction heater is started, eddy currents are generated in the casting, causing the temperature of the casting to rise rapidly, thus achieving the effect of efficient heating. After heating to the target temperature, the lifting mechanism descends, and then the casting is taken out through the casting outlet for the next operation.

[0012] (2) The support plate and the baffle can prevent the risk of the casting falling into the interior of the box when the casting is put in or taken out.

[0013] (3) The setting of the positioning groove and the guide rod can make the lifting of the placement plate more stable. Description of the Drawings

[0018] The present utility model will be further described below with reference to the drawings.

[0019] As Figures 1 - 4 shown, a heat treatment device for processing roll castings includes a box body 1, a lifting mechanism, an electromagnetic induction heater 2 and a heating coil 3. A partition 4 is vertically arranged in the box body 1. The partition 4 divides the box body 1 into two left and right spaces. The left space is a heating space 5, and the right space is an installation space 6. The electromagnetic induction heater 2 is installed in the installation space 6. The heating coil 3 is installed at the top of the heating space 5 and is electrically connected to the electromagnetic induction heater 2. The lifting mechanism is installed at the bottom of the heating space 5 and is directly below the heating coil 3. Casting inlets 7 are respectively arranged on the front and rear sides of the box body 1, and the casting inlets 7 and the casting outlet are opened on the heating space 5.

[0020] The lifting mechanism includes a lifting cylinder 8 and a support plate 9. A placement plate 10 is provided at the top of the lifting cylinder 8. The support plate 9 is fixedly connected between the casting inlet 7 and the casting outlet. A through hole is formed in the support plate 9, and the top of the lifting cylinder 8 passes through the through hole and is connected to the bottom of the placement plate 10. A positioning groove is formed in the support plate 9, and a positioning block matching the positioning groove is provided at the bottom of the placement plate 10. The cooperation of the positioning groove and the positioning plate can ensure that the placement plate 10 is always located directly below the heating coil 3. A guide rod 11 is vertically provided on the support plate 9, and the placement plate 10 is slidably connected to the guide rod 11. The placement plate 10 slides up and down along the guide rod 11 with stable lifting. A limit plate is provided at the top of the guide rod 11 to prevent the placement plate 10 from detaching from the guide rod 11.

[0021] When heating the casting, first place the casting on the placement plate 10 from the casting inlet 7. A clamping device can be provided on the placement plate 10 to further fix the casting. Then, the lifting cylinder 8 extends to jack up the placement plate 10, so that the casting rises into the heating coil 3. With the start of the electromagnetic induction heater 2, eddy currents will be generated in the casting, causing the temperature of the casting to quickly rise to the target temperature, thus achieving the effect of efficient heating of the casting. Then, the lifting cylinder 8 retracts, causing the placement plate 10 to slide down along the guide rod 11, and the casting returns to the initial position. Finally, take out the heated casting through the casting outlet for subsequent heat treatment operations. Baffles are fixedly connected to both sides of the support plate 9, so that there is no risk of the casting falling into the interior of the box body 1 during the process of putting in or taking out the casting. The device heats the casting quickly and evenly, and can improve the efficiency of heat treatment of the casting.
