Description

Technical Field

[0001] This utility model relates to the field of high-temperature sintering molding equipment processing, and in particular to a high-temperature sintering molding equipment for stainless steel sintered filter elements. Background Technology

[0002] High-temperature sintering molding equipment mainly uses high-temperature heating to cause atomic diffusion and fusion at the contact points of loose metal powder particles. Finally, after cooling, it forms a whole with a porous structure and a certain strength. This production process does not use organic binders, and the produced products have a smooth surface and very little particle shedding. This is crucial for fields with extremely high cleanliness requirements, such as semiconductors, food, pharmaceuticals, and bioengineering.

[0003] However, the existing high-temperature sintering molding device for stainless steel sintered filter elements still has some problems in practical use: before the stainless steel metal powder is put into the sintering furnace during high-temperature sintering, the powder will continuously enter the sintering furnace through the opening of the funnel. This makes it difficult to accurately control the amount of powder entering the sintering furnace each time, which may lead to instability and uniformity of product performance during the sintering process.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0027] Please see Figures 1-5 In this embodiment of the present invention, a high-temperature sintering forming device for stainless steel sintered filter elements includes an outer funnel 1, an inner funnel 2 fixedly connected to the top of the inner wall of the outer funnel 1, and a shielding and feeding adjustment mechanism 3 provided on one side of the lower end of the inner funnel 2.

[0028] The material feeding adjustment mechanism 3 includes a connecting support plate 301, which is fixed to one side of the lower end of the inner funnel 2. A drive motor 302 is fixedly connected to one side of the upper end of the connecting support plate 301 through a through hole. A turntable 303 is fixedly connected to the output shaft of the drive motor 302. A lever 304 is fixedly connected to the upper edge of the turntable 303. A blade 305 is rotatably connected to one end of the connecting support plate 301 through a bearing. A baffle 306 is fixedly connected to the upper end of the blade 305.

[0029] The diameter of one end of the lever 304 is slightly smaller than the inner diameter of the elliptical slot of the blade 305, so that when the drive motor 302 drives the turntable 303 and the lever 304 to rotate, the lever 304 can be smoothly inserted into the elliptical slot of the blade 305, thereby pushing the blade 305 to rotate around the bearing without jamming.

[0030] One end of the baffle 306 is slightly larger than the discharge port at the bottom of the inner funnel 2, so that when the baffle 306 completely covers the discharge port, there is a small gap between the baffle 306 and the edge of the discharge port. This ensures the sealing of the baffle 306 when it completely covers the discharge port. At the same time, this small gap also prevents the baffle 306 from rubbing excessively against the edge of the discharge port during rotation, thereby reducing wear and noise.

[0031] Please see Figures 1-3 A fixed bracket 4 is fixedly connected to the bottom of the surface of the outer funnel 1, and a working platform 5 is fixedly connected to the lower end of the fixed bracket 4. A conduit 6 is fixedly connected to the lower end of the outer funnel 1.

[0032] The outer funnel 1 is connected to the working platform 5 through the fixed bracket 4. The working platform 5 provides a stable support foundation for the entire sintering device, ensuring that the device will not be displaced due to external forces or its own vibration during the high-temperature sintering process.

[0033] Please see Figures 1-3 One end of the conduit 6 is fixedly connected to the sintering furnace 7, and the upper end of the working platform 5 near the middle is fixedly connected to the connecting support plate 8.

[0034] One end of the conduit 6 is flush with the inner wall of the sintering furnace 7. When the pressure plate 10 is pressed down to perform the sintering operation, the flush state between the conduit 6 and the inner wall of the sintering furnace 7 will not hinder the pressing action of the pressure plate 10, thus ensuring the continuity of material supply and the stability of the pressing operation of the pressure plate 10 during the sintering process, thereby enabling the entire high-temperature sintering and forming process to be carried out efficiently and in an orderly manner.

[0035] Please see Figures 1-2 An electric push rod 9 is fixedly connected to one end of the connecting support plate 2 8, and a pressure plate 10 is fixedly connected to one end of the electric push rod 9. The surface of the pressure plate 10 is slidably connected to the inner wall of the sintering furnace 7.

[0036] The position of fixing one end of the connecting support plate 2 8 to the electric push rod 9 is such that the electric push rod 9 is on the same axis as the center point of the pressure plate 10. This fixing method ensures that when the electric push rod 9 pushes the pressure plate 10, the direction of the force can be accurately transmitted along the center line of the pressure plate 10, avoiding the tilting or jamming of the pressure plate 10 due to uneven force.

[0037] The pressure plate 10 is closely attached to the inner wall of the sintering furnace 7, which makes the pressure plate 10 stable during movement and prevents it from shaking or shifting. This ensures the uniformity of material pressure during sintering and further improves the forming quality of the stainless steel sintered filter element. At the same time, this close fit design also reduces the risk of material leakage during sintering and ensures the stability of the sintering environment.

[0038] Please see Figures 1-2 A supporting steel component 11 is fixedly connected to the middle of the lower end of the working platform 5. A cooling box 12 is fixedly connected to the upper end of the supporting steel component 11. Perforated heat dissipation columns 13 are fixedly connected to both sides of the cooling box 12 through through holes.

[0039] Symmetrical porous heat dissipation columns 13 are arranged on both sides of the cooling box 12, and the porous heat dissipation columns 13 have multiple holes. Cold air is blown into the chamber from the opening on the cooling box 12. These porous heat dissipation columns 13 not only increase the heat dissipation area, but also, through the design of multiple holes, allow the cold air to be distributed more evenly inside the cooling box 12, which can quickly remove the heat generated during the sintering process and ensure that the sintered filter element is formed at a suitable temperature.

[0040] Please see Figures 2-3 The lower ends of the working platform 5 are fixedly connected to the equipment base 14 by through slots on both sides. The front and back sides of the equipment base 14 are fixedly connected to the side reinforcement plates 15. The lower end of the sintering furnace 7 is connected to the plug block 16 by bolt thread.

[0041] Side reinforcement plates 15 are installed on both sides of the equipment base 14 symmetrically and are located near the bottom of the equipment base 14. Their function is to enhance the overall stability of the equipment base 14. During the operation of the sintering furnace 7, they can effectively withstand the vibration and stress generated by high-temperature sintering, prevent the equipment base 14 from deforming or being damaged due to long-term stress, and thus ensure the stable operation of the entire stainless steel sintering filter element high-temperature sintering forming device.

[0042] The plug 16 is inserted at the feeding port of the sintering furnace 7. Its function is to keep the stainless steel metal powder in a fixed state during the heating and pressing process, preventing the metal powder from flowing out. At the same time, when the material needs to be discharged after sintering, the plug 16 can be easily and quickly removed, so that the sintered stainless steel filter element can be discharged smoothly from the feeding port. This ensures the continuity of the entire sintering process and avoids production accidents and material waste caused by metal powder leakage.

[0043] The working principle of this utility model is as follows:

[0044] First, metal powder is put into the inner funnel 2. The drive motor 302 is started to drive the turntable 303 and the pusher block 304 to rotate. When the blade 305 rotates around the bearing, the baffle 306 will rotate accordingly, and the metal powder will flow out. The baffle 306 will block the discharge port of the inner funnel 2 at timed intervals. Then the metal powder will slowly slide down to the feeding area of ​​the sintering furnace 7 through the outer funnel 1 and the guide tube 6.

[0045] Secondly, during the descent of the metal powder, the heating element starts to work, preheating the metal powder entering the feeding area of ​​the sintering furnace 7, so that it gradually approaches the suitable sintering temperature range, preparing for the subsequent sintering process. When the preheated metal powder enters the sintering furnace 7, under the set sintering temperature and time, physical and chemical changes such as fusion and diffusion occur between the metal powder particles, gradually forming the initial shape of a stainless steel sintered filter element with a certain strength and pore structure.

[0046] Finally, the electric push rod 9 is activated to drive the pressure plate 10 to press the stainless steel sintered filter element into shape. The plug 16 is released to allow the stainless steel sintered filter element to fall automatically into the cooling box 12. Cold air is poured into the chamber from the top of the cooling box 12 and the heat is quickly discharged through the porous heat dissipation column 13 to complete the sintering operation.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
