Description

Technical Field

[0002] Powder metallurgy sintering is a high-temperature processing technology that further binds pressed or loosely packed powder bodies to improve their strength and other properties. It is one of the important processes in powder metallurgy. During sintering, powder particles undergo physical and chemical processes such as mutual flow, diffusion, melting, and recrystallization, which further densifies the powder body and eliminates some or all of its pores. Existing sintering processes require high temperatures, thus generating heat energy. The release of this heat energy not only affects the surrounding working environment but also consumes energy. Traditional powder metallurgy green blank sintering equipment is not conducive to collecting heat energy and then using the principle of generating air pressure based on the heat energy accumulation to drive the components and maintain a constant working environment temperature. Furthermore, traditional powder metallurgy green blank sintering equipment is not conducive to using electrically driven structures to accelerate heat exchange and prevent heat energy from dissipating into the surrounding environment.

[0011] Furthermore, the thermostat component has a U-shaped cavity inside, and an irregular cavity is formed inside the upper part of the thermostat component, with the air pressure component located at the lower end of the irregular cavity.

[0012] Furthermore, the pneumatic assembly includes an elastic windproof cloth and a lightweight block disposed on the upper end of the elastic windproof cloth.

Detailed Implementation

[0026] 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.

[0027] To address the technical challenge of traditional powder metallurgy green sintering equipment being inconvenient for collecting heat energy and then using the principle of heat accumulation to generate gas pressure to drive components and maintain a constant working environment, such as... Figures 1-6 As shown, the following preferred technical solutions are provided:

[0028] A powder metallurgy green blank sintering equipment capable of collecting and utilizing heat energy includes a sintering main component 1 and a pushing device 4 disposed on one side of the sintering main component 1. A pushing block 5 is movably mounted on the upper end of the pushing device 4. An L-shaped transmission assembly 3 is disposed on the side of the sintering main component 1. A constant temperature assembly 2 is disposed on the outer side of the sintering main component 1, covering the sintering main component 1. A heat energy barrier assembly 6 is disposed on the side of the sintering main component 1 facing the pushing block 5. A pneumatic pressure assembly 7 and an electric drive assembly 8 are disposed inside the upper end of the constant temperature assembly 2, with multiple sets of the electric drive assembly 8. The heat energy generated by the operation of the sintering main component 1 enters the interior of the constant temperature assembly 2 through the barrier of the heat energy barrier assembly 6, accumulating heat energy. The impact air pressure component 7, in turn, electrically drives the electric drive component 8, allowing heat energy to be exchanged inside the constant temperature component 2, maintaining the constant temperature of the constant temperature component 2, and allowing the heat energy generated by the sintering main component 1 to be released to the outside in a constant temperature manner. A cooling component 21 is provided at the upper end of the constant temperature component 2, which plays the role of releasing cold air. A pressure relief valve 22 is provided on the side of the constant temperature component 2, and multiple pressure relief valves 22 are provided. A feed plate 11 is provided on one side of the sintering main component 1, and the feed plate 11 is at the same horizontal position as the bottom end of the push block 5. Metallurgical powder parts 9 are provided inside the L-shaped transmission component 3, and the feed plate 11 is used to receive the metallurgical powder parts 9 transmitted by the L-shaped transmission component 3.

[0029] The heat-blocking component 6 includes an L-shaped plate 61 disposed on one side of the sintering main component 1, with two sets of L-shaped plates 61. An electrically driven lifting door 62 is movably disposed between the two sets of L-shaped plates 61. An air venting groove 63 is provided inside the electrically driven lifting door 62. A connecting plate 64 is disposed directly above the electrically driven lifting door 62 and is fixedly connected to the upper end of the electrically driven lifting door 62. A telescopic air duct 65 is disposed on the upper end of the connecting plate 64, with three sets of telescopic air ducts 65. A fixing plate 66 is disposed on the upper end of the three sets of telescopic air ducts 65. A curved one-way valve pipe 67 is disposed on the upper end of the fixing plate 66, with three sets of curved one-way valve pipes 67. One end of each set of telescopic air ducts 65 is connected to the interior of the air venting groove 63, and the other end is connected to each set of curved one-way valve pipes 67. One end of the curved one-way valve pipe 67 of the assembly is connected to the thermostatic component 2. The curved one-way valve pipe 67 is equipped with a pumping structure for absorbing heat energy. The thermostatic component 2 has a U-shaped cavity 23 inside and an irregular cavity 24 inside the upper end of the thermostatic component 2. The air pressure component 7 is located at the lower end of the irregular cavity 24. The air pressure component 7 includes an elastic windproof cloth 71 and a lightweight block 72 set on the upper end of the elastic windproof cloth 71. An electrical component 73 is set on the upper end of the lightweight block 72. A fixed fitting block 74 is also set directly above the lightweight block 72. The upper end of the lightweight block 72 is fitted inside the fixed fitting block 74. The upper end of the fixed fitting block 74 is fixedly connected to the inner wall of the irregular cavity 24. The elastic windproof cloth 71 is fixedly connected to the four sides of the irregular cavity 24. The lightweight block 72 is located at the center of the elastic windproof cloth 71.

[0030] Specifically, when sintering is required, the parts are transferred to the feed plate 11 via the L-shaped transfer assembly 3. Under the action of the pushing device 4, the pusher block 5 pushes the parts into the sintering main component 1. At this time, the heat-resistant assembly 6 rises to its highest position, and the parts are sintered through the internal structure of the sintering main component 1. The electrically driven lifting door 62 then descends until it contacts the feed plate 11. During this process, the telescopic duct 65 extends and retracts. The heat generated during sintering is transported to the three sets of telescopic ducts 65 through the venting groove 63. The connecting plate 64 prevents the heat inside the sintering main component 1 from dissipating into the surrounding environment. The heat-resistant assembly 6 and the sintering main component 1 are spaced apart, ensuring that oxygen does not enter the sintering main component 1 and increase the ambient temperature. The heat inside the three sets of telescopic ducts 65 then passes through the fixed plate 66 and the bent one-way valve pipe 67 into the irregular cavity 24. The entering heat is located at the lower end of the elastic windproof cloth 71. As the heat continuously... As heat flows in, the air pressure at the lower end of the irregular cavity 24 increases, causing the elastic windproof cloth 71 to change from a horizontal state to an arched state, thus raising the lightweight block 72. When the lightweight block 72 rises to its apex, the electrical component 73 contacts the fixed fitting block 74, thereby electrically driving the electrical drive assembly 8. This allows the heat energy at the lower end of the irregular cavity 24 to enter the interior of the U-shaped cavity 23. At the same time, it also electrically drives the cooling assembly 21, which generates cold air that enters the interior of the U-shaped cavity 23. The mixing of cold and hot air inside cavity 3 results in a more moderate temperature, thus preventing the outer shell of the sintering main component 1 from accidentally injuring workers during the sintering process. When the internal thermal pressure of the irregular cavity 24 is low, the electrical component 73 and the fixed fitting block 74 no longer contact each other, which shuts off the function of the electrical drive component 8. When the internal pressure of the U-shaped cavity 23 is high enough, the gas is released through multiple pressure relief valves 22. At this time, the temperature of the released gas is relatively mild and will not raise the temperature of the surrounding working environment, thus ensuring the work efficiency of the workers.

[0031] To address the technical challenge of traditional powder metallurgy green sintering equipment being unable to utilize electrically driven structures to accelerate heat exchange and prevent heat dissipation into the surrounding environment, such as... Figures 6-7 As shown, the following preferred technical solutions are provided:

[0032] The electric drive assembly 8 includes a fixed motor 81 fixedly installed inside the upper end of the thermostatic assembly 2. A drive shaft 82 is connected to the lower end of the fixed motor 81 via a shaft. A rotating paddle 83 is installed on the outside of the drive shaft 82. The electric drive assembly 8 also includes a shaped connecting pipe 84 that communicates with the shaped cavity 24. A ball valve 85 is installed inside the shaped connecting pipe 84. The ball valve 85 is connected to the drive shaft 82 and rotates with the rotation of the drive shaft 82. One end of the shaped connecting pipe 84 is connected to the shaped cavity 24, and the other end is connected to the U-shaped cavity 23.

[0033] Specifically, the electric drive component 8 first enables the fixed motor 81 to work. The drive of the fixed motor 81 causes the drive shaft 82 to rotate, which in turn causes the ball valve 85 to rotate. The rotating ball valve 85 connects the irregular connecting pipe 84 with the irregular cavity 24 and the U-shaped cavity 23. The heat energy inside the irregular cavity 24 can enter the U-shaped cavity 23. At the same time, the rotation of the drive shaft 82 drives multiple sets of rotating paddles 83 to rotate, mixing the heat energy and cold air, accelerating the mixing efficiency, and ensuring the constant temperature effect of the constant temperature component 2.
