Description

Technical Field

[0001] This invention relates to the field of alloy material processing technology, and in particular to a processing equipment for precision machining of alloy materials. Background Technology

[0002] Alloys are materials composed of two or more metallic or non-metallic elements, possessing excellent physical and chemical properties. The preparation of cemented carbide mainly includes steps such as raw material preparation, drying, mixing, pressing, sintering, and surface treatment. Sintering involves placing the pressed blank at a high temperature, causing the metal binder to melt and infiltrate between the metal carbide particles, thereby forming a dense structure.

[0003] In the existing technology, when sintering alloy blanks, the blanks are usually placed directly on a high-temperature resistant plate, and then the plate is placed in a heating furnace for sintering. Obviously, this will cause the side of the blank in contact with the plate to be heated differently from the other sides, forming a heating dead zone, which will reduce the heating uniformity of the blank and directly affect the quality of the sintering process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a processing device for precision machining of alloy materials, which solves the technical problems of low heating uniformity and poor sintering quality of alloy blanks during sintering. It has the advantages of effectively improving the heating uniformity of alloy blanks and eliminating heating dead zones.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a processing equipment for precision machining of alloy materials, including a mounting frame, a fixed horizontal plate on the mounting frame, a processing square tube fixedly mounted on the upper end of the fixed horizontal plate, an alloy blank placed inside the processing square tube, blank sintering mechanisms on both the left and right sides of the processing square tube, a blank clamping mechanism inside the processing square tube, a vertical conveying mechanism for feeding the blank at the lower end of the fixed horizontal plate, a spray cooling mechanism below the vertical conveying mechanism, and a gas adding mechanism at the upper end of the processing square tube. After the operator places the alloy blank inside the vertical conveying mechanism, it will enter the processing square tube under the action of the vertical conveying mechanism. Next, the blank sintering mechanism and the blank clamping mechanism will perform high-temperature sintering processing on the alloy blank. During the sintering process, the gas adding mechanism will introduce argon gas into the processing square tube, which can effectively prevent oxides on the surface of the alloy blank from being adsorbed into the alloy interior. The mechanism includes symmetrical vertical grooves on the side walls inside the processed square tube. A rectangular slider is movably installed inside the vertical grooves, and a movable round shaft is rotatably connected to the rectangular slider. A drive gear is fixedly sleeved on the outside of the movable round shaft. A limit block is driven to the end of the movable round shaft. A rectangular slot is opened inside the limit block. A return spring is fixedly connected between the movable round shaft and the inner wall of the rectangular slot. A telescopic push rod is set at the lower end of the inner cavity of the vertical groove. The upper end of the telescopic push rod is fixedly connected to the lower end of the rectangular slider. An external air pump is detachably installed on the fixed horizontal plate. The air outlet of the external air pump is connected to an air guide hose. The air guide hose passes through the inside of the movable round shaft and connects to the inside of the rectangular slot. An installation assembly is set on the outside of the movable round shaft. A protective net is detachably installed on the installation assembly. When the external air pump is powered on, it will inflate the inside of the rectangular slot through the air guide hose. Subsequently, the two limit blocks will move closer to each other under the action of air pressure, thereby completing the clamping and limiting of the alloy blank.

[0006] Preferably, the sintering mechanism for the blank includes a sintering cavity formed inside the processing tube, gas spray guns are fixedly installed on the left and right sides of the processing tube, heating nozzles are provided on the inner wall of the sintering cavity, a gas storage tank is detachably installed on the back of the mounting frame, and an exhaust pipe is connected between the gas storage tank and the gas spray gun. In use, the gas spray gun will rapidly heat the inside of the sintering cavity through the heating nozzles, thereby completing the sintering process of the alloy blank.

[0007] Preferably, a vertical rack matching the drive gear is fixedly installed on the inner wall of the side wall groove. When the drive gear moves upward synchronously with the rectangular slider, it will rotate under the action of the vertical rack. When the drive gear rotates, it will cause the movable circular shaft to rotate synchronously.

[0008] Preferably, the mounting assembly includes a mounting ring fixedly sleeved on the outside of the movable circular shaft, a mounting rod fixedly connected to the mounting ring, and the mounting rod fixedly connected to the anti-fall net. Initially, the anti-fall net is in a vertical state. When the movable circular shaft rotates, the anti-fall net will rotate synchronously with the movable circular shaft.

[0009] Preferably, the end of the movable circular shaft extends into the rectangular slot and is fixedly installed with a rectangular sliding plug. The outer surface of the rectangular sliding plug is tightly fitted with the rectangular slot. Both the movable circular shaft and the rectangular sliding plug have coaxial clearance slots for the air guide hose to pass through. Initially, the limiting block will be in a retracted state under the action of the return spring. When the external air pump inflates the rectangular slot through the air guide hose, the limiting block will extend outward.

[0010] Preferably, the vertical conveying mechanism includes an electric push rod fixedly installed at the lower end of the fixed horizontal plate. The lower end of the electric push rod is fixedly connected to a movable platform. A rotating platform is movably installed at the upper end of the movable platform. The rotating platform is made of high-temperature resistant material. A drive motor for driving the rotating platform is fixedly installed at the lower end of the movable platform. Two limiting grooves are symmetrically opened at the upper end of the rotating platform. Limiting components and limiting springs are set inside the limiting grooves. A sealing ring is set on the upper surface of the movable platform. After the operator places the alloy blank at the upper end of the rotating platform, the two limiting components will limit the alloy blank under the action of the limiting springs, thereby preventing the alloy blank from falling during the feeding process.

[0011] Preferably, the limiting component includes a limiting slider movably installed inside the limiting groove, one end of the limiting spring contacts the limiting slider, the other end of the limiting spring is fixedly connected to the inner wall of the limiting groove, and a heat-resistant block is fixedly installed on the upper end of the limiting slider. When the limiting slider moves under the action of the limiting spring, the heat-resistant block will move synchronously, and the heat-resistant block will limit the alloy blank when it moves.

[0012] Preferably, the spray cooling mechanism includes a liquid storage tank fixed on a mounting frame, a vertical piston slidably connected inside the liquid storage tank, a drain pipe fixedly installed on the outside of the liquid storage tank, a spray nozzle fixedly installed at the upper end of the drain pipe, a fan blade movably installed below the fixed horizontal plate, and a drive motor for driving the fan blade to rotate fixedly installed on the back of the mounting frame. When the vertical piston moves downward along the liquid storage tank, it causes the clean water inside the liquid storage tank to enter the interior of the drain pipe and be sprayed outward through the spray nozzle.

[0013] Preferably, the lower end of the vertical piston is in close contact with the inner wall of the liquid storage tank, and the upper end of the vertical piston extends to the top of the liquid storage tank. When the movable platform moves downward, it will contact the upper end of the vertical piston, thereby causing it to move downward synchronously.

[0014] Preferably, the gas adding mechanism includes a sealing disc detachably installed on the upper end of the processing square tube. The lower end of the sealing disc is provided with several exhaust nozzles, and the upper end of the sealing disc is provided with an argon gas storage tank. An electromagnetic valve is provided between the argon gas storage tank and the sealing disc. A flow meter is fixedly installed on the electromagnetic valve. After the electromagnetic valve is turned on, the argon gas inside the argon gas storage tank will enter the interior of the sintering cavity through the exhaust nozzles.

[0015] By means of the above technical solution, the present invention provides a processing equipment for precision machining of alloy materials, which has at least the following beneficial effects:

[0016] 1. By setting up a blank clamping mechanism, the present invention can automatically lift the alloy blank upward and make it flip back and forth by utilizing the cooperation between the limiting block and the drive gear, so that the side of the alloy blank in contact with the rotating table faces the heating nozzle, which can eliminate the heating dead angle and make all parts of the alloy blank be heated evenly, greatly improving the uniformity of heating.

[0017] 2. By setting up a blank clamping mechanism, the present invention can continuously clamp the alloy blank by utilizing the cooperation between the external air pump and the limiting block. Moreover, the clamping force can be changed according to the volume change of the alloy blank, which has high sensitivity. In this way, even if the volume of the alloy blank shrinks during the sintering process, it will not fall off due to insufficient clamping force.

[0018] 3. By setting up a blank clamping mechanism, the present invention can automatically block the bottom of the alloy blank when it is flipped by the cooperation between the installation components and the anti-fall protective net. In this way, even if the alloy blank falls due to the failure of the external air pump, the alloy blank will not directly collide with the rotating platform, which can effectively avoid damage to the alloy blank.

[0019] 4. By setting up a blank sintering mechanism, the present invention can automatically and quickly sinter the exterior of the alloy blank by utilizing the cooperation between two gas torches. Moreover, the symmetrical arrangement of the two heating nozzles can improve the sintering efficiency and uniformity to a certain extent.

[0020] 5. By setting up a vertical conveying mechanism, the present invention can automatically complete vertical feeding and unloading by utilizing the cooperation between the movable platform and the electric push rod, which can effectively improve the efficiency of sintering. Moreover, during the feeding and rotary sintering process, the limiting component will always clamp and limit the alloy blank, which can prevent the alloy blank from falling during the feeding process and avoid slippage between the alloy blank and the rotating table.

[0021] 6. By setting up a vertical conveying mechanism, the present invention utilizes the cooperation between the rotating frustum and the limiting component to heat and solidify the side of the alloy blank before high-temperature sintering, so that it has a certain strength, thereby avoiding damage to the alloy blank by the limiting block during the clamping and flipping process.

[0022] 7. By setting up a spray cooling mechanism, the present invention can automatically and rapidly cool the outer surface of the alloy billet during the unloading process by utilizing the cooperation between the spray nozzle and the fan blades. This can effectively prevent burns to the workers' hands during the subsequent manual transfer of the alloy billet, and greatly improve the safety of the sintering operation.

[0023] 8. By setting up a gas adding mechanism, the present invention utilizes the cooperation between the electromagnetic valve and the argon storage tank to automatically add argon gas into the sintering cavity during the sintering process, thereby forming a protective gas ring on the surface of the alloy blank, preventing it from reacting with oxygen to generate bubbles and oxidation, which can improve the quality of the alloy blank sintering process to a certain extent.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] according to Figure 1 , Figure 2 as well as Figure 3As shown, a precision machining equipment for alloy materials includes a mounting frame 1, a fixed horizontal plate 2 on the mounting frame 1, a machining cylinder 3 fixedly mounted on the upper end of the fixed horizontal plate 2, an alloy blank 9 placed inside the machining cylinder 3, blank sintering mechanisms 4 on both the left and right sides of the machining cylinder 3, a blank clamping mechanism 5 inside the machining cylinder 3, a vertical conveying mechanism 6 for feeding the blank at the lower end of the fixed horizontal plate 2, a spray cooling mechanism 7 below the vertical conveying mechanism 6, and a gas adding mechanism 8 at the upper end of the machining cylinder 3. After the operator places the alloy blank 9 inside the vertical conveying mechanism 6, it will enter the machining cylinder 3 under the action of the vertical conveying mechanism 6. Next, the blank sintering mechanism 4 and the blank clamping mechanism 5 will perform high-temperature sintering processing on the alloy blank 9. During the sintering process, the gas adding mechanism 8 will introduce argon gas into the machining cylinder 3, which can effectively prevent oxides on the surface of the alloy blank 9 from being adsorbed into the alloy interior.

[0040] Specifically, the blank sintering mechanism 4 includes a sintering cavity 401 opened inside the processing square tube 3. Gas spray guns 402 are fixedly installed on the left and right sides of the processing square tube 3. Heating nozzles 403 are provided on the inner wall of the sintering cavity 401. A gas storage tank 404 is detachably installed on the back of the mounting frame 1. An exhaust pipe 405 connects the gas storage tank 404 and the gas spray gun 402. In use, the gas spray gun 402 will rapidly heat the inside of the sintering cavity 401 through the heating nozzles 403, thereby completing the sintering process of the alloy blank 9.

[0041] In this embodiment, after the alloy blank 9 enters the sintering cavity 401 under the action of the vertical conveying mechanism 6, the gas torch 402 ignites the gas and sprays flames into the sintering cavity 401 through the heating nozzle 403, thereby sintering the alloy blank 9.

[0042] In this embodiment, by setting up a blank sintering mechanism 4, the cooperation between two gas torches 402 can automatically and quickly sinter the exterior of the alloy blank 9. Moreover, the two heating nozzles 403 are symmetrically arranged, which can improve the sintering efficiency and uniformity to a certain extent.

[0043] Example 2

[0044] according to Figure 1 , Figure 3 , Figure 4 , Figure 5 as well as Figure 11As shown, based on Embodiment 1, the blank clamping mechanism 5 includes symmetrically formed side wall vertical grooves 501 inside the processing square tube 3. A vertical rack matching the drive gear 504 is fixedly installed on the inner wall of the side wall vertical groove 501. When the drive gear 504 moves upward synchronously with the rectangular slider 502, it rotates under the action of the vertical rack. The rotation of the drive gear 504 causes the movable circular shaft 503 to rotate synchronously. A rectangular slider 502 is movably installed inside the side wall vertical groove 501, and a rotatable connection is made to the rectangular slider 502. A movable circular shaft 503 is externally fitted with a drive gear 504. A limit block 505 is connected to the end of the movable circular shaft 503. A rectangular slot 506 is formed inside the limit block 505. The end of the movable circular shaft 503 extends into the rectangular slot 506 and is fixedly fitted with a rectangular sliding plug. The outer surface of the rectangular sliding plug is tightly fitted with the rectangular slot 506. Initially, the limit block 505 is in a retracted state under the action of a return spring 507. When the external air pump 509 passes through the air guide hose... When air is injected into the rectangular slot 506, the limiting block 505 extends outward. A return spring 507 is fixedly connected between the movable round shaft 503 and the inner wall of the rectangular slot 506. A telescopic push rod 508 is provided at the lower end of the inner cavity of the side wall vertical slot 501. The upper end of the telescopic push rod 508 is fixedly connected to the lower end of the rectangular slider 502. An external air pump 509 is detachably installed on the fixed horizontal plate 2. The air outlet of the external air pump 509 is connected to an air guide hose 510. The interiors of the movable round shaft 503 and the rectangular slider are coaxially opened. There is a clearance groove through which the air guide hose 510 passes. The air guide hose 510 passes through the inside of the movable round shaft 503 and connects to the inside of the rectangular empty slot 506. An installation component 511 is provided on the outside of the movable round shaft 503. A fall-proof protective net 512 is detachably installed on the installation component 511. When the external air pump 509 is powered on, it will inflate the inside of the rectangular empty slot 506 through the air guide hose 510. Subsequently, the two limit blocks 505 will approach each other under the action of air pressure, thereby completing the clamping and limiting of the alloy blank 9.

[0045] Specifically, the mounting component 511 includes a mounting ring fixedly sleeved on the outside of the movable circular shaft 503. A mounting rod is fixedly connected to the mounting ring, and the mounting rod is fixedly connected to the anti-fall net 512. Initially, the anti-fall net 512 is in a vertical state. When the movable circular shaft 503 rotates, the anti-fall net 512 will rotate synchronously with the movable circular shaft 503.

[0046] In this embodiment, as can be seen from the above, when the alloy blank 9 first enters the interior of the sintering cavity 401, it will undergo rotational sintering in cooperation with the rotating frustum 603 and the heating nozzle 403, thereby solidifying the side surface of the alloy blank 9.

[0047] After a preset time, the rotating frustum 603 will stop rotating and align the end of the alloy blank 9 with the limiting block 505. Next, the external air pump 509 will inflate the rectangular slot 506 with air through the air guide hose 510, so that the two limiting blocks 505 will contact the front and rear ends of the alloy blank 9 respectively, thus completing the clamping.

[0048] After clamping, the rectangular slider 502 will reciprocate vertically under the action of the telescopic push rod 508. When the rectangular slider 502 moves, the movable circular shaft 503, the drive gear 504 and the limit block 505 will move synchronously. When the limit block 505 moves upward, the alloy blank 9 will move upward synchronously. When the drive gear 504 moves upward, it will rotate the movable circular shaft 503 synchronously through the cooperation with the vertical rack. When the movable circular shaft 503 rotates, the alloy blank 9 will rotate ninety degrees, so that the side of the alloy blank 9 that contacts the rotating frustum 603 is in a vertical state, which can also greatly improve the uniformity of heating of the alloy blank 9.

[0049] In addition, when the movable shaft 503 rotates, the mounting assembly 511 will rotate synchronously. Therefore, after the movable shaft 503 rotates 90 degrees clockwise, the anti-fall guard 512 will move to the bottom of the alloy blank 9. In this way, even if the alloy blank 9 falls during the upward rotation, it will not directly collide with the rotating platform 603, which can effectively prevent the alloy blank 9 from being damaged during the sintering process.

[0050] After sintering, the alloy blank 9 will detach from the limiting block 505 and fall above the rotating platform 603. Next, the movable platform 602 will move downward under the action of the electric push rod 601 to transport the alloy blank 9 outward.

[0051] This embodiment, by setting up a blank clamping mechanism 5, utilizes the interaction between the limiting block 505 and the drive gear 504 to automatically lift the alloy blank 9 upwards and make it reciprocate and rotate, so that the side of the alloy blank 9 in contact with the rotating frustum 603 faces the heating nozzle 403, which can eliminate heating dead zones and ensure that all parts of the alloy blank 9 are heated evenly, greatly improving the uniformity of heating; moreover, by setting up a blank clamping mechanism 5, this embodiment, through the interaction between the external air pump 509 and the limiting block 505, can continuously clamp the alloy blank 9, and the clamping force can be... The clamping mechanism is highly sensitive to changes in the volume of the alloy blank 9, ensuring that even if the alloy blank 9 shrinks during sintering, it will not fall due to insufficient clamping force. In addition, this embodiment uses a blank clamping mechanism 5, which, through the cooperation between the mounting component 511 and the anti-fall protective net 512, can automatically shield the bottom of the alloy blank 9 when it is flipped. This prevents the alloy blank 9 from falling even if it falls due to a malfunction of the external air pump 509, thus effectively avoiding direct collision between the alloy blank 9 and the rotating platform 603.

[0052] Example 3

[0053] according to Figure 1 , Figure 2 , Figure 6 as well as Figure 7 As shown, based on the above embodiment, the vertical conveying mechanism 6 includes an electric push rod 601 fixedly installed at the lower end of the fixed horizontal plate 2. The lower end of the electric push rod 601 is fixedly connected to a movable platform 602. A rotating frustum 603 is movably installed at the upper end of the movable platform 602. The rotating frustum 603 is made of high-temperature resistant material. A drive motor 604 for driving the rotating frustum 603 is fixedly installed at the lower end of the movable platform 602. Two limiting grooves 605 are symmetrically opened at the upper end of the rotating frustum 603. Limiting components 606 and limiting springs 607 are provided inside the limiting grooves 605. A sealing ring 608 is provided on the upper surface of the movable platform 602. After the operator places the alloy blank 9 at the upper end of the rotating frustum 603, the two limiting components 606 will limit the alloy blank 9 under the action of the limiting springs 607, thereby preventing the alloy blank 9 from falling during the feeding process.

[0054] Specifically, the limiting component 606 includes a limiting slider movably installed inside the limiting slide groove 605. One end of the limiting spring 607 contacts the limiting slider, and the other end of the limiting spring 607 is fixedly connected to the inner wall of the limiting slide groove 605. A heat-resistant locking block is fixedly installed on the upper end of the limiting slider. When the limiting slider moves under the action of the limiting spring 607, the heat-resistant locking block will move synchronously. When the heat-resistant locking block moves, it will limit the alloy blank 9.

[0055] In this embodiment, during use, the operator places the alloy blank 9 between two heat-resistant blocks. Then, the two limiting sliders move closer to each other under the action of the limiting spring 607. During the movement of the limiting sliders, the heat-resistant blocks will contact the side of the alloy blank 9, thereby completing the limiting and preventing the alloy blank 9 from falling off during the feeding process.

[0056] Subsequently, the movable platform 602 will move vertically upward under the action of the electric push rod 601. When the movable platform 602 moves upward, the rotating platform 603 will move synchronously, thereby transporting the alloy blank 9 into the interior of the processing square tube 3. Next, the gas torch 402 will sinter the exterior of the alloy blank 9.

[0057] Moreover, during the sintering process, the rotating frustum 603 will rotate at a certain speed under the action of the drive motor 604, which can improve the uniformity of heating to a certain extent, thereby improving the sintering effect.

[0058] After sintering, the movable platform 602 will move vertically downward under the action of the electric push rod 601. When the movable platform 602 moves downward, it will transport the alloy blank 9 to the bottom of the processing square tube 3, thereby completing the unloading.

[0059] This embodiment, by setting up a vertical conveying mechanism 6, utilizes the cooperation between the movable platform 602 and the electric push rod 601 to automatically complete vertical feeding and unloading, which can effectively improve the efficiency of sintering. Moreover, during the feeding and rotary sintering process, the limiting component 606 will always clamp and limit the alloy blank 9, which can prevent the alloy blank 9 from falling during the feeding process and avoid slippage between the alloy blank 9 and the rotating table 603. In addition, by setting up a vertical conveying mechanism 6, this embodiment utilizes the cooperation between the rotating table 603 and the limiting component 606 to heat and solidify the side of the alloy blank 9 before high-temperature sintering, so that it has a certain strength, thereby avoiding damage to the alloy blank 9 by the limiting block 505 during the clamping and flipping process.

[0060] Example 4

[0061] according to Figure 1 , Figure 2 , Figure 8 as well as Figure 9As shown, based on the above embodiment, the spray cooling mechanism 7 includes a liquid storage tank 701 fixed on the mounting frame 1. A vertical piston 702 is slidably connected inside the liquid storage tank 701. The lower end of the vertical piston 702 is tightly fitted against the inner wall of the liquid storage tank 701, and the upper end of the vertical piston 702 extends above the liquid storage tank 701. When the movable platform 602 moves downward, it contacts the upper end of the vertical piston 702, thereby causing it to move downward synchronously. A drain vertical pipe 703 is fixedly installed on the outside of the mounting bracket 1. A spray head 704 is fixedly installed at the upper end of the drain vertical pipe 703. A blower blade 705 is movably installed below the fixed horizontal plate 2. A drive motor 706 for driving the blower blade 705 to rotate is fixedly installed on the back of the mounting bracket 1. When the vertical piston 702 moves downward along the liquid storage tank 701, it will cause the clean water inside the liquid storage tank 701 to enter the interior of the drain vertical pipe 703 and spray it outward through the spray head 704.

[0062] In this embodiment, as can be seen from the above, after the sintering process is completed, the movable platform 602 will move downward under the action of the electric push rod 601. When the movable platform 602 moves downward, it will transport the alloy blank 9 to the bottom of the processing square tube 3, thereby completing the unloading.

[0063] Furthermore, when the moving platform 602 moves downward, it will contact the vertical piston 702 and cause it to move downward synchronously. When the vertical piston 702 moves downward, it will push the clean water inside the liquid storage tank 701 into the drain vertical pipe 703 and spray it outward through the spray nozzle 704. After the clean water is sprayed out, it will contact the outer surface of the alloy blank 9. At the same time, the fan blade 705 will rotate under the action of the drive motor 706, thereby blowing air on the surface of the alloy blank 9, which can quickly cool the surface of the alloy blank 9.

[0064] This embodiment, by setting up a spray cooling mechanism 7, utilizes the cooperation between the spray nozzle 704 and the fan blade 705 to automatically and rapidly cool the outer surface of the alloy blank 9 during the unloading process. This can effectively prevent burns to the workers' hands during the subsequent manual transfer of the alloy blank 9, and greatly improve the safety of the sintering operation.

[0065] Example 5

[0066] according to Figure 1 , Figure 2 as well as Figure 10As shown, based on the above embodiment, the gas adding mechanism 8 includes a sealing disc 801 detachably installed on the upper end of the processing square tube 3. The lower end of the sealing disc 801 is provided with several exhaust nozzles, and the upper end of the sealing disc 801 is provided with an argon storage tank 802. An electromagnetic valve 803 is provided between the argon storage tank 802 and the sealing disc 801. A flow meter 804 is fixedly installed on the electromagnetic valve 803. After the electromagnetic valve 803 is turned on, the argon gas inside the argon storage tank 802 will enter the interior of the sintering cavity 401 through the exhaust nozzles.

[0067] In this embodiment, during the sintering process, the electromagnetic valve 803 is turned on under the control of the operator. After the electromagnetic valve 803 is turned on, the argon gas inside the argon storage tank 802 will enter the interior of the sintering cavity 401 through several exhaust nozzles, thereby forming a protective gas ring on the outside of the alloy material to prevent the alloy blank 9 from being lost due to reaction with oxygen.

[0068] Moreover, during the gas addition process, the flow meter 804 will monitor the amount of argon gas added in real time, which can effectively avoid the excessive use of argon gas and avoid waste.

[0069] In this embodiment, by setting up a gas adding mechanism 8, and utilizing the cooperation between the electromagnetic valve 803 and the argon storage tank 802, argon gas can be automatically added into the sintering cavity 401 during the sintering process, thereby forming a protective gas ring on the surface of the alloy blank 9, preventing it from reacting with oxygen to generate bubbles and oxidation, which can improve the quality of the sintering process of the alloy blank 9 to a certain extent.

[0070] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
