Description

Technical Field

[0001] The present invention relates to the technical field of sintering equipment, and particularly to a sintering equipment for preparing ferrite soft magnetic composite materials. Background Art

[0002] Ferrite is also known as ferrites or magnetic porcelain. Ferrite is a ceramic crystal formed by combining iron oxides and various other powdered metals (usually manganese, zinc, nickel, and cobalt), and then undergoing extrusion and high-temperature sintering for a certain period of time. The electromagnetic properties of ferrite materials are related to the added metal components, as well as the time, temperature, and atmosphere during the sintering process.

A conveyor belt 10 is wound between the two electric rollers 8. The conveyor belt 10 is made of a high-temperature resistant and pore-free material. An accommodation groove 7 is opened above the box body 1. On both sides of the top of the inner wall of the box body 1, isolation components 14 are installed through bolts, and the top ends of the isolation components 14 are located inside the accommodation groove 7. The two isolation components 14 cooperate with the conveyor belt 10 to divide the inside of the box body 1 into a preheating area 15, a sintering area 16, and a cooling area 17.

On both sides of the bottom of the inner wall of the accommodation groove 7, a flipping component 13 is installed through bolts, and the flipping component 13 is located inside the sintering area 16. The flipping component 13 includes two lifting oil cylinders 30. The model of the lifting oil cylinder 30 is preferably HYG-50.

The output end of the telescopic oil cylinder 37 is installed with a partition plate 38 through bolts. The isolation component 14 further includes a housing 36. Operating one of the telescopic oil cylinders 37 to start, the output end of the telescopic oil cylinder 37 will drive the partition plate 38 to slide inside the housing 36, and the partition plate 38 will retract into the housing 36. Subsequently, operating the electric roller 8 to start, the conveyor belt 10 will drive the material to move inside the box body 1.

The heating modules 11 and 12 are preferably Kanthal Super 1800 type silicon molybdenum rods, and are configured with a PID temperature control system (such as Omron E5CC series) and an SCR power controller. The heating modules 11 and 12 need to adopt a split-type radiation heating structure to evenly cover the space of the sintering area 16.

[0036] In still another embodiment provided by the present invention, as Figure 5-6As shown, the cooling component 4 includes a casing 24. On one outer wall of the casing 24, three first grooves 25 are formed. On the other outer wall of the casing 24, three second grooves 29 are formed. The second grooves 29 communicate with the first grooves 25 and the cooling area 17. At the center of the bottom of the inner wall of the first groove 25, a blower 26 is installed by bolts. The model of the blower 26 is preferably a DF multi-wing centrifugal fan, and the air inlet end of the blower 26 extends to the outside of the casing 24. Inside one of the second grooves 29, a plurality of heating elements 27 are installed by bolts. Inside the other second groove 29, a cooling coil 28 is installed by bolts. The cooling coil 28 is connected to the cooling water supply equipment in the workshop. The blower 26 forces air supply, and in cooperation with the cooling coil 28, the material can be quickly cooled to room temperature. By starting the heating elements 27 and the cooling coil 28, gradient cooling can be achieved, enabling the material to cool at a rate of 5 - 10 °C / min, avoiding sudden cooling and cracking.

[0037] In yet another embodiment provided by the present invention, as Figure 3 As shown, the reflux component 2 includes a jet box 18. The jet box 18 is installed at the bottom of one side of the inner wall of the placement groove 7 by bolts. On one outer wall of the jet box 18, a plurality of jet holes 23 are formed, and the jet holes 23 communicate with the preheating area 15. At the center of the top of one outer wall of the jet box 18, an air delivery pipe 19 is inserted. One end of the air delivery pipe 19 is threadedly connected to a cylinder body 20. Inside the cylinder body 20, a suction fan 21 is installed by bolts. The model of the suction fan 21 is preferably Detong HTF - 350. The material to be sintered is placed on the conveyor belt 10 inside the preheating area 15. Subsequently, the box door 5 is closed, and then the suction fan 21 is started. The suction fan 21 will draw the hot air inside the sintering area 16 into the jet box 18. Subsequently, the hot air will be blown into the preheating area 15 through the jet holes 23, increasing the temperature inside the preheating area 15 and realizing the preheating of the material. The other end of the cylinder body 20 is inserted with a connecting pipe 22, and one end of the connecting pipe 22 extends into the sintering area 16.

[0038] Working principle: When applying this device, the heating module 11 and the heating module 12 can be started first to heat the inside of the sintering area 16, so that the temperature inside the sintering area 16 rises. Subsequently, one of the cabinet doors 5 is opened, and the material to be sintered is placed on the conveyor belt 10 inside the preheating area 15. Then the cabinet door 5 is closed. Subsequently, the exhaust fan 21 is turned on, and the exhaust fan 21 will draw the hot air inside the sintering area 16 into the preheating area 15, so that the temperature inside the preheating area 15 rises, realizing the preheating of the material. After preheating for a period of time, one of the telescopic cylinders 37 is operated to start. The output end of the telescopic cylinder 37 will drive the partition plate 38 to slide inside the housing 36, and the partition plate 38 will retract into the housing 36. Subsequently, the electric roller 8 is operated to start, and the conveyor belt 10 will drive the material to move inside the box body 1. As it moves, the material will enter the sintering area 16. Subsequently, the telescopic cylinder 37 is operated again to start, and the partition plate 38 will slide down, and the bottom of the partition plate 38 will closely adhere to the conveyor belt 10. Subsequently, the rotation speed of the electric roller 8 is operated to adjust the transportation speed of the conveyor belt 10, so that the material moves slowly inside the sintering area 16 to meet the time required for sintering. When the material moves into the frame body 34, the two lifting cylinders 30 will start. The output end of the lifting cylinder 30 will drive the frame body 34 to descend, and the frame body 34 will fall on the conveyor belt 10. Subsequently, the air pump 33 is operated to start, and the air pump 33 will inflate the airbag 35. The inflated airbag 35 will wrap the material. The lifting cylinder 30 is operated again to make the frame body 34 rise. When it rises to a certain height, the rotary motor 32 will start. The rotary motor 32 will drive the frame body 34 to rotate around the mounting shell 31, so that the material is heated from multiple angles. After being heated for a period of time, the material is flipped 180 degrees so that the bottom of the material faces up. After the flipping is completed, the above operation of the lifting cylinder 30 is repeated. The position of the frame body 34 descends, and the bottom of the material after flipping contacts the conveyor belt 10. Subsequently, the air pump 33 is reversed to start, and the air pump 33 will extract the gas inside the airbag 35. The airbag 35 no longer clamps the material. Then the lifting cylinder 30 is controlled to start, and the frame body 34 will return to its original position; Subsequently, the electric roller 8 is continued to be started, and the electric roller 8 will drive the material to continue to move inside the sintering area 16, and the material continues to be sintered; After the sintering is completed, the above steps are repeated to operate another isolation component 14. The sintered material will enter the cooling area 17. During this process, the heating sheet 27 and the water supply pump connected to the cooling coil 28 are started. The heating sheet 27 will increase the temperature inside one of the grooves 29, so that the air blown out by one of the blowers 26 has a certain temperature, realizing the primary cooling of the material. Subsequently, as the conveyor belt 10 transports, the second blower 26 will blow out relatively warm air to cool the material. And when the third blower 26 is started subsequently, it will cooperate with the cooling coil 28 to blow out cold air to quickly cool the material to avoid cracking due to sudden cooling; When rapid cooling is required at the same time, the blower 26 is operated to force air supply, and it will cooperate with the cooling coil 28 to quickly cool down to room temperature;Subsequently, open another cabinet door 5, and the sintered materials can be taken out.

Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
