Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment devices, in particular to a temperature rising and tempering device for the production of aluminum-nickel-cobalt magnetic steel. Background Art

[0002] The tempering device is used for tempering general metal parts in the heating furnace, and for annealing and aging heat treatment of light alloy parts such as aluminum alloy die castings, pistons, and aluminum plates. Al-Ni-Co magnets are hard alloys synthesized from aluminum, nickel, iron and other metals. Although the aluminum-nickel alloy here is hard, it is very brittle and cannot be cold processed. It must be made by casting or sintering. Therefore, the production of Al-Ni-Co magnets here must require the addition of a tempering device to be carried out smoothly.

[0003] China Patent Authorization Announcement No.: CN206529499U, Authorization Announcement Date: September 29, 2017, discloses a tempering device for tempering a workpiece after quenching, the tempering device comprises a tempering mechanism, a heating mechanism for providing a hot air flow to the tempering mechanism, and a drainage component arranged in the tempering mechanism for storing the workpiece and guiding the hot air flow to flow through the workpiece; the tempering device also comprises an air inlet pipe and an air return pipe respectively connected to the tempering mechanism and the heating mechanism at both ends; the tempering mechanism comprises a tempering furnace, and an air outlet cavity arranged in the tempering furnace and connected to the air inlet pipe. The disadvantage of this technical solution is that the workpiece is loaded into the drainage container, and then the hot air obtained by combustion in the burner is introduced to perform the tempering of the workpiece, but the workpiece here is always stationary (the process does not involve moving the workpiece during the tempering work), so the introduced hot air is not balanced for the tempering of the workpiece, which affects the tempering work efficiency.

[0004] In summary, a device can be provided to allow the tempering heat treatment work of the workpiece to be balanced. Utility Model Content

[0005] The utility model aims to overcome the deficiency of the prior art that the workpiece is kept stationary for tempering heat treatment, and provides a heating tempering device for aluminum-nickel-cobalt magnetic steel production which is installed to allow the workpiece to be tempered heat treated during the rotating motion.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heating and tempering device for the production of aluminum-nickel-cobalt magnetic steel, comprising a burner, a combustion furnace, a blower and a tempering furnace, the combustion furnace is connected to the burner, the blower is connected to the combustion furnace, a return air duct is installed on the combustion furnace, a drainage chamber is provided in the tempering furnace, a ventilation block and a plurality of rolling tubes are installed on the tempering furnace, the ventilation block is placed on the inner wall of the tempering furnace, a plurality of ventilation holes are provided on the ventilation block, and the plurality of ventilation holes are evenly distributed, two fan plates are installed at the ventilation holes, the positions of the two fan plates correspond to each other on the left and right, the fan plate is detachably connected to the ventilation block, a plurality of rolling tubes are evenly distributed at the bottom end of the tempering furnace, the rolling tube is detachably connected to the tempering furnace, and the combustion furnace is connected to the drainage chamber through the return air duct.

When the fan plates can't withstand the impact exerted by the hot air, they can rotate, that is, open the ventilation holes, and then the hot air can smoothly enter the drainage cavity, and the aluminum-nickel-cobalt magnetic steel material in the drainage cavity undergoes tempering heat treatment. Not only that, several rolling tubes are evenly distributed at the bottom of the tempering furnace, and the rolling tubes are detachably connected to the tempering furnace. In this way, the entry of hot air will naturally blow the AlNiCo magnetic steel material, and the AlNiCo magnetic steel material will roll on the rolling tubes, thus achieving the purpose of installing the workpiece to perform tempering heat treatment during the rotational motion.

In this way, not only does the conveying rail support the tempering furnace, but also hot air enters the drainage chamber, and after heat treatment of the aluminum-nickel-cobalt magnetic steel material in the drainage chamber, it can be introduced into the drainage chamber and discharged from the vents. An air inlet pipe is installed at the front end of the conveying guide rail, and the conveying guide rail is connected with the blower through the air inlet pipe. The work of the blower is to guide the cooled air through the combustion furnace again and then introduce it into the drainage chamber to carry out heat treatment of the aluminum-nickel-cobalt magnetic steel material in the drainage chamber. This cycle is repeated to improve the heat treatment efficiency of the aluminum-nickel-cobalt magnetic steel material. An inclined block is installed at the rear end of the conveying guide rail.

[0020] like Figure 2 , Figure 2 and Figure 3 As shown, the tempering furnace 4 is provided with an opening, which is connected to the drainage chamber 17, and a switch door 19 is installed at the opening, and the switch door 19 is detachably connected to the tempering furnace 4. A temperature sensor 1 18 is installed on the return air duct 8, a temperature sensor 2 20 is installed in the drainage chamber 17, a single-chip microcomputer and a display are installed on the switch door 19, and the temperature sensor 1 18 and the temperature sensor 2 20 are both electrically connected to the single-chip microcomputer, and the single-chip microcomputer is electrically connected to the display. A through hole 9 is provided at the top of the tempering furnace 4, and the return air duct 8 is connected to the drainage chamber 17 through the through hole 9. A conveying guide rail 5 is installed at the bottom of the tempering furnace 4, and a plurality of vents 7 are installed on the conveying guide rail 5. The plurality of vents 7 are symmetrically distributed around the conveying guide rail 5, and the drainage chamber 17 is connected to the vents 7. An air inlet pipe 6 is installed at the front end of the conveying guide rail 5, and the conveying guide rail 5 is connected to the blower 3 through the air inlet pipe 6. An inclined block 11 is installed at the rear end of the conveying guide rail 5, and the position of the inclined block 11 corresponds to the position of the opening. A plurality of rolling bearings 1 are installed on the ventilation block 10, and the rolling bearings 1 correspond to the fan plates 15 one by one. The rolling bearings 1 include an inner ring 1 and an outer ring 1, and the outer ring 1 is connected to the ventilation block 10. A rolling shaft 14 is installed at one of the inner rings, and the rolling shaft 14 is connected to the fan plates 15. Rolling bearings 2 are installed on both left and right ends of the rolling tube 12. The rolling bearings 2 include inner rings 2 and outer rings 2. The outer rings 2 are connected to the tempering furnace 4. The rolling tube 12 is connected to the inner rings 2. A capillary tube is installed on the rolling tube 12. The capillary tube is connected to the return air duct 8. A plurality of air outlet holes 16 are provided on the rolling tube 12. The plurality of air outlet holes 16 are symmetrically distributed with the center of the rolling tube 12 as the base point.

[0021] First, the AlNiCo magnetic steel material to be heat treated is passed into the drainage cavity 17 in the tempering furnace 4 along the inclined block 11 installed at the rear end of the conveying guide rail 5, and a number of rolling tubes 12 are installed at the bottom end of the tempering furnace 4, and the AlNiCo magnetic steel material is already placed on the rolling tubes 12. Then the switch door 19 on the tempering furnace 4 is controlled to close the opening on the tempering furnace 4. The connection between the switch door 19 and the tempering furnace 4 can be selected as a hinge connection, so that the AlNiCo magnetic steel material can be stably limited in the drainage cavity 17.

[0022] Then, fuel is put into the burner 1 to carry out combustion work, and the combustion furnace 2 is connected to the burner 1, and the blower 3 is connected to the combustion furnace 2, so the operation of the blower 3 can be controlled to introduce air into the combustion furnace 2. After the hot air produced by the combustion of the burner 1 enters the combustion furnace 2, under the action of the wind force of the wind blown by the blower 3, the hot air can only float toward the return air duct 8 until it is introduced through the through hole 9 at the top of the tempering furnace 4. However, the ventilation block 10 is placed on the inner wall of the tempering furnace 4. In other words, the hot air from the return air duct 8 is blocked by the ventilation block 10. Of course, there are a number of ventilation holes 13 evenly distributed on the ventilation block 10, and two rolling bearings are installed at the ventilation holes 13. The rolling bearings are connected to the fan The plates 15 correspond one by one, the outer ring of the rolling bearing 1 is connected to the ventilation block 10, and the inner ring of the rolling bearing 1 is equipped with a rolling shaft 14, and the fan plate 15 is connected to the rolling shaft 14. The hot air here is blocked, and it will naturally exert an impact on the fan plate 15 at the ventilation hole 13. Although the fan plate 15 is affected by the rolling shaft 14 and the rolling bearing 1, under the support effect of the ventilation block 10, there is always an upper limit. Then the increasing impact of the hot air gradually increases, and the fan plate 15 can be smoothly pushed. Under the rolling of the rolling shaft 14, the ventilation hole 13 is opened, and the hot air can smoothly enter the drainage chamber 17, and then the aluminum nickel cobalt magnetic steel material in the drainage chamber 17 is heat treated. It should be noted here that a coil spring needs to be installed on the rolling shaft 14, so that without the impact of the hot air, the fan plate 15 can naturally return to its original position to close the ventilation hole 13.

[0023] Not only that, the hot air still has an impact when it enters the drainage cavity 17, so the aluminum nickel cobalt magnetic steel material will naturally rotate under the influence of the hot air impact. At the same time, rolling bearings 2 are installed on both ends of the rolling tube 12. The outer ring 2 of the rolling bearing 2 is connected to the tempering furnace 4, and the rolling tube 12 is connected to the inner ring 2 of the rolling bearing 2. The fine tube installed on the rolling tube 12 is also connected to the return air duct 8, so the hot air in the return air duct 8 can enter the rolling tube 12 through the fine tube. The rolling tube 12 is provided with a plurality of air outlet holes 16, and the plurality of air outlet holes 16 are symmetrically distributed with the center of the rolling tube 12 as the base point. In this way, hot air can impact the AlNiCo magnetic steel material through the air outlet 16, which not only has a heat treatment effect, but also enhances the moving power of the AlNiCo magnetic steel material. In this way, the workpiece is installed to undergo tempering heat treatment during rotation. Of course, the distribution of several air outlets 16 also allows the rolling tube 12 to work more evenly on the AlNiCo magnetic steel material. In order to ensure that the AlNiCo magnetic steel material can be heat treated under the rotation of the rolling tube 12, the rolling tube 12 can also be connected to a servo motor. By rotating the servo motor shaft on the servo motor, the rolling tube 12 connected to the servo motor shaft can be rotated.

[0024] Of course, the heat treatment of AlNiCo magnetic steel materials is subject to temperature conditions. Therefore, the hot air temperature information sensed by the temperature sensor 18 on the return air duct 8 and the hot air temperature information sensed by the temperature sensor 2 20 in the drainage cavity 17 can be transmitted to the single-chip microcomputer. After processing by the single-chip microcomputer, the processed information is transmitted to the display. The display can directly display the temperature values ​​at the two places, and then determine whether to strengthen the combustion of the fuel.

[0025] Not only that, a conveying guide rail 5 is installed at the bottom of the tempering furnace 4, and a plurality of vents 7 are installed on the conveying guide rail 5. The plurality of vents 7 are symmetrically distributed around the conveying guide rail 5, and the drainage cavity 17 is connected to the vents 7, so the wind after working through the drainage cavity 17 can be discharged through the vents 7. Not only that, an air inlet pipe 6 is installed at the front end of the conveying guide rail 5, and the conveying guide rail 5 is connected to the blower 3 through the air inlet pipe 6, so part of the wind will enter the tempering furnace 4 through the air inlet pipe 6 and then through the return air pipe 8 to perform the heat treatment of the aluminum-nickel-cobalt magnetic steel material. This cycle is repeated to achieve a better heat treatment effect of the aluminum-nickel-cobalt magnetic steel material.

[0026] Of course, the blower 3 and the display here need to be electrically connected to the switch assembly, and the switch assembly needs to be electrically connected to the power supply, so that the blower 3 and the display can work smoothly.
