Description

Technical Field

[0001] This invention belongs to the field of sintering technology, specifically a powder metallurgy sintering equipment for an intelligent heat treatment production line for powder metallurgy. Background Technology

[0002] Powder metallurgy materials require effective processing to be prepared. Powder metallurgy materials are made through formulation, pressing, sintering and post-treatment. Sintering is an important step in the preparation of powder metallurgy materials, which involves placing the pressed parts in a closed furnace with a reducing atmosphere.

[0003] A powder metallurgy sintering device for an intelligent heat treatment production line, with publication number CN120306636A, is described. It loads metallurgical powder materials onto a sliding and tilting sintering rack, then adjusts the distance between the rack and the heat source inside the sintering chamber to ensure uniform heating of the powder materials. This prevents uneven heating between powder materials and ensures optimal overall heating. However, the metallurgical powder materials inside the sintering rack are pre-pressed and require sintering for shaping and fixing. Therefore, during the actual sintering process, the structure of the pressed devices is relatively loose. When the sintering rack is tilted, significant deformation and material detachment of the metallurgical powder materials can easily occur, affecting the quality of the final sintered product. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of material deformation during sintering of metallurgical powders in existing technologies, the technical solution adopted in this invention is: a powder metallurgy sintering equipment for an intelligent heat treatment production line for powder metallurgy, comprising: The sintering chamber has guide components symmetrically arranged on the upper and lower sides of the inner wall of the sintering chamber, and a heating component is slidably connected inside the guide components; The intermediate frame is located in the middle of the inner wall of the sintering box, and the intermediate frame has a container inserted inside; Pressure relief components are symmetrically arranged on the left and right sides of the inner wall of the sintering chamber; The guiding component includes: A shell-splitting clamp, wherein guide rails are evenly provided in the inner cavity of the shell-splitting clamp; A guide top seat, the inner wall of which is slidably connected to the top of the outer surface of the shell clamping plate; The heating component includes: The sleeve housing has its outer surface slidably connected to the inner cavity of the shell-splitting clamp via a guide rail. Motor rollers are symmetrically arranged on both sides of the outer surface of the sleeve housing, and the outer surfaces of these motor rollers are also tactilely connected to the inner cavity of the shell-splitting clamp via guide rails. Each motor roller is driven by an independent micro-motor, allowing the sleeve housing to slide along the guide rails of the shell-splitting clamp. The flame tip has an outer surface that fits into the inner wall of the sleeve housing, and the bottom end of the flame tip extends to the outside of the sleeve housing.

[0005] Furthermore, the sintering chamber includes: The heat-insulating shell has a connecting groove in the upper part of its inner cavity, through which the pressure relief component inside the heat-insulating shell exchanges heat with the outside. The enclosed rotating plates are symmetrically arranged on the front of the heat insulation shell, and the outer surface of the enclosed rotating plates is rotatably connected to the outer surface of the heat insulation shell through a rotating shaft; The control panel has its inner cavity of the enclosed rotating plate sleeved with the outer surface of the control panel.

[0006] Furthermore, the guiding component includes: The wall-mounted connecting shell has its outer surface snapped into the middle of the inner wall of the heat-insulating shell, and the interior of the wall-mounted connecting shell is a hollow structure. The pressurizing pipe is symmetrically arranged at both ends of the inner wall of the wall-connecting shell, and the air inlet of the pressurizing pipe extends to the outside of the heat insulation shell. After the pressurizing pipe pressurizes the inside of the wall-connecting shell, it will distribute the pressure to the inner cavity of each guide top seat, thereby pushing the shell-splitting clamp inside the guide top seat, so that the shell-splitting clamp as a whole can perform vertical sliding motion. The outer surface of the guide top seat is inserted into the outer surface of the wall-mounted connecting shell through an air inlet.

[0007] Furthermore, the heating component includes: A fuel tank, the outer surface of which is fitted with the outer surface of a wall-connecting shell through a groove, and the feed port of the fuel tank extends to the outside of the heat-insulating shell; A metal telescopic tube is provided, with its top end inserted into the inner cavity of the fuel tank and its end away from the fuel tank inserted into the inner cavity of the flame nozzle. The metal telescopic tube has strong heat resistance and can undergo elastic deformation. After liquid fuel is filled into the inner fuel tank from the external feed port, the fuel tank supplies fuel to each flame nozzle through the metal telescopic tube.

[0008] Furthermore, the mid-position frame includes: A heat-conducting frame, wherein the outer surface of the heat-conducting frame is fixedly connected to the middle part of the inner wall of the heat-insulating shell, and contact grooves are symmetrically opened on the upper and lower sides of the inner cavity of the heat-conducting frame. A side-push pressure plate, the outer surface of which is fixedly connected to one side of the inner wall of the heat conduction rack; Card holder slide plate, the outer surface of which is slidably connected to the inner wall of the heat conduction frame; A compression connecting sleeve, one side of which is fixedly connected to the outer surface of the card holder slide, and the other end of which is inserted into the outer surface of the side push pressure plate through a tube.

[0009] Furthermore, the container component includes: The docking plate shell has symmetrically opened heat-receiving grooves on its upper and lower sides. The outer surface of the docking plate shell is inserted into the inner wall of the heat-conducting frame. After the pre-pressed metallurgical powder is loaded into the interior of the docking plate shell, the two docking plate shells on both sides are joined together to form an insert plate body, which is inserted directly into the interior of the heat-conducting frame to realize the feeding operation. Side inserts are symmetrically arranged on the left and right sides of the inner wall of the docking plate shell. The outer surface of the docking plate shell is inserted into the inner cavity of the card holder slide through the side inserts. The merged docking plate shell is inserted into the inner cavity of the card holder slide through the side inserts on both sides, so that the side push pressure plate can push the docking plate shell to make stable horizontal sliding movement, change the heated part of the docking plate shell, and achieve the effect of uniform heating.

[0010] Furthermore, the pressure relief component includes: A filling box, the upper part of which is inserted into the side of the wall-connecting shell, and the outer surface of which is snapped into the upper part of the inner wall of the heat-insulating shell; A temperature-sensing top plate, the bottom of which is inserted into the top of the filling box, and the top of the temperature-sensing top plate is provided with a mating groove, and the top of the temperature-sensing top plate is connected to the communicating groove of the heat insulation shell through the mating groove.

[0011] Furthermore, the pressure relief component also includes: An inner control board has a temperature control chip inserted into its front end. The outer surface of the inner control board is connected to the bottom of the inner wall of the filling box through a heat insulation layer. The inner control board senses the actual temperature inside the heat insulation shell through the temperature control chip. The connecting rotating cylinder is evenly inserted into the upper part of the inner control board, which can connect the air inside the filling box with the air inside the heat insulation shell. The outer surface of the connecting rotating cylinder is rotatably connected to the inner cavity of the filling box through a rotating groove. The inner control board drives the connecting rotating cylinder to rotate around its axis through a micro motor in the inner cavity.

[0012] Furthermore, the connecting rotating drum includes: A vertical rotating cylinder, the bottom end of which extends into the interior of the insulation layer of the filling box, and the bottom end of the vertical rotating cylinder is inserted into the upper part of the inner control plate through a rotating end head. Symmetrical through slots are provided on both sides of the inner cavity of the vertical rotating cylinder. The perforated partition is symmetrically inserted into both sides of the inner cavity of the vertical rotating cylinder through through slots. When either side of the perforated partition on both sides of the vertical rotating cylinder is aligned with the outside of the filling box through the rotating slot, the air inside the heat insulation shell can dissipate heat to the outside of the heat insulation shell through the docking slot at the top. If the perforated partition and the rotating slot are misaligned, the rotating slot at this point is blocked. The internal filter plate is located in the middle of the vertical rotating cylinder cavity to filter the passing air.

[0013] The beneficial effects of this invention are as follows: 1. This device can sinter the pre-pressed metallurgical powder material loaded into the docking plate shell through the heating components on the upper and lower sides to achieve its shaping effect. During the sintering process, the flame tip will slide back and forth along the guide rail of the shell-splitting clamp, so that the flame spray range of the flame tip will evenly cover the entire heat conduction frame. Therefore, the processing work can be carried out while ensuring that the internal metallurgical powder material does not move significantly, thereby avoiding a series of problems such as large deformation and material loss of the metallurgical powder material before it is fully shaped due to motion inertia.

[0014] 2. After the upper and lower shell-split plates are combined, they form a shell that covers the central frame. As the flame nozzle moves with the shell-split plates, it is moved to a position closer to the central frame. Therefore, the high-temperature flame emitted by the flame nozzle will fully act on the outer surface of the central frame, preventing the flame from spreading randomly inside the heat insulation shell and causing the temperature of all areas inside the heat insulation shell to rise, thereby reducing fuel utilization. Since the combined shell-split plates can cover the flame, there will be no overflowing flames scorching the inner wall of the heat insulation shell and causing damage to the inner wall of the heat insulation shell.

[0015] 3. To avoid the heating dead zone caused by the obstruction between the heat-conducting frame and the heated groove of the mating plate shell, which would lead to uneven heating of the internal material of the mating plate shell, the mating plate shell is reciprocated by the clamping slides on both sides during the actual heating process, thereby eliminating the heating dead zone. Due to the slow speed, the actual heating area of ​​the flame tip is increased. Therefore, while ensuring the stability of the internal metallurgical material, the number of flame tips used is reduced, thereby reducing power consumption and improving thermal energy utilization.

[0016] 4. During heat treatment inside the insulation shell, high pressure is generated due to high temperature. During long-term operation, it is necessary to periodically reduce the pressure through pressure relief components to avoid production accidents. When the insulation shell is initially heated, it is necessary to ensure its internal sealing. At this time, the connecting drum blocks the slot on the side of the filling box through its vertical rotating drum, so that the insulation shell achieves a near-sealed effect, thereby improving the internal heat preservation effect and achieving the purpose of rapid heating. The pressure reduction range can also be adjusted by adjusting the actual number of connecting drums that unblock the slot on the side of the filling box to meet different pressure reduction needs.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example 1, please refer to Figures 1-4 This invention provides a technical solution: a powder metallurgy sintering equipment for an intelligent heat treatment production line for powder metallurgy, comprising: The sintering chamber 1 has guide components 2 symmetrically arranged on the upper and lower sides of the inner wall of the sintering chamber 1, and the heating component 3 is slidably connected inside the guide component 2. The middle frame 4 is located in the middle of the inner wall of the sintering box 1, and the middle frame 4 has a container component 5 inserted inside it. Pressure relief components 6 are symmetrically arranged on the left and right sides of the inner wall of the sintering chamber 1; Guide component 2 includes: The shell-splitting clamp 24 has guide rails 25 evenly distributed in its inner cavity. The guide top seat 23 is slidably connected to the top of the outer surface of the shell clamping plate 24. Heating component 3 includes: The sleeve housing 33 has its outer surface slidably connected to the inner cavity of the shell-splitting plate 24 via a guide rail 25. Motor rollers 35 are symmetrically arranged on both sides of the outer surface of the sleeve housing 33, and the outer surfaces of the motor rollers 35 are tactilely connected to the inner cavity of the shell-splitting plate 24 via the guide rail 25. Each motor roller 35 is driven by an independent micro motor, allowing the sleeve housing 33 to slide along the guide rail 25 of the shell-splitting plate 24. The flame tip 34 has its outer surface fitted with the inner wall of the sleeve housing 33, and its bottom end extends to the outside of the sleeve housing 33.

[0021] Sintering chamber 1 includes: The heat insulation shell 11 has a connecting groove in the upper part of its inner cavity. The pressure relief component 6 inside the heat insulation shell 11 exchanges heat with the outside through the connecting groove at the top. The closed rotating plate 12 is symmetrically arranged on the front of the heat insulation shell 11, and the outer surface of the closed rotating plate 12 is rotatably connected to the outer surface of the heat insulation shell 11 through a rotating shaft. The inner cavity of the control panel 13 is sleeved with the outer surface of the control panel 13.

[0022] Guide component 2 includes: The wall-mounted connecting shell 21 has its outer surface snapped into the middle of the inner wall of the heat-insulating shell 11, and the interior of the wall-mounted connecting shell 21 is a hollow structure. The pressurizing pipe 22 is symmetrically arranged at both ends of the inner wall of the wall-connecting shell 21, and the air inlet of the pressurizing pipe 22 extends to the outside of the heat insulation shell 11. After the pressurizing pipe 22 pressurizes the inside of the wall-connecting shell 21, it will distribute the pressure to the inner cavity of each guide top seat 23, thereby pushing the shell-splitting clamp 24 inside the guide top seat 23, so that the shell-splitting clamp 24 as a whole performs vertical sliding motion. The outer surface of the guide top seat 23 is inserted into the outer surface of the wall-mounted connecting shell 21 through the air inlet.

[0023] Heating component 3 includes: The fuel tank 31 has an outer surface that is fitted with the outer surface of the wall-mounted connecting shell 21 through a groove, and the feed port of the fuel tank 31 extends to the outside of the heat-insulating shell 11. The metal telescopic tube 32 is inserted into the inner cavity of the fuel tank 31 at its top end and into the inner cavity of the flame nozzle 34 at the other end. The metal telescopic tube 32 has strong heat resistance and can undergo elastic deformation. After liquid fuel is filled into the inner fuel tank 31 from the external feed port, the fuel tank 31 supplies fuel to each flame nozzle 34 through the metal telescopic tube 32.

[0024] First, the pre-pressed metallurgical powder material is placed into the interior of the docking plate shell 51 in sequence. Then, the docking plate shells 51 on both sides are spliced ​​into a complete plate. Then, the front closed rotating plate 12 is opened, and the plate is inserted straight into the heat conduction frame 41 in the center. Ensure that the side insert plates 52 on both sides are inserted into the grooves of the side card plate slides 44. Then, the closed rotating plate 12 is closed to complete the preparation work.

[0025] Before the heat treatment is carried out, the guide components 2 located on the upper and lower sides work first. The pressurization pipe 22 pressurizes the inside of the wall-connecting shell 21, causing the guide top seat 23 to push the shell-cutting clamp 24 to slide to one side of the central frame 4. Then the shell-cutting clamps 24 on the upper and lower sides are joined together to form a shell that covers the central frame 4. When the shell-cutting clamp 24 slides, it will drive all the sleeve shells 33 to slide synchronously through the guide slide rail 25. At this time, the metal telescopic tube 32 is stretched, and the flame nozzle 34 will also approach the central frame 4.

[0026] During heat treatment, the fuel tank 31 supplies power to the flame nozzle 34 through each fuel tank 31. The flame nozzle 34 directly sprays flame onto the outer surface of the heat conduction frame 41 to achieve heating. The sleeve shell 33 actively slides along the guide rail 25 of the shell-splitting plate 24 through the motor rollers 35 on both sides. Since the length of its metal telescopic tube 32 is limited, each sleeve shell 33 will slide back and forth a certain distance, thereby ensuring that the working range of the flame nozzles 34 on the upper and lower sides can completely cover the outer surface of the heat conduction frame 41, so as to achieve a more comprehensive heat treatment of the internal assembly 5.

[0027] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the mid-position frame 4 includes: The heat conduction frame 41 has its outer surface fixedly connected to the middle part of the inner wall of the heat insulation shell 11, and the upper and lower sides of the inner cavity of the heat conduction frame 41 are symmetrically provided with contact grooves. Side-push pressure plate 42, the outer surface of side-push pressure plate 42 is fixedly connected to one side of the inner wall of heat conduction frame 41; Card holder slide plate 44, the outer surface of card holder slide plate 44 is slidably connected to the inner wall of heat conduction frame 41; The compression connecting sleeve 43 is fixedly connected to the outer surface of the card holder slide plate 44 on one side, and the other end of the compression connecting sleeve 43 is inserted into the outer surface of the side push pressure plate 42 through the insertion tube.

[0028] Container component 5 includes: The docking plate shell 51 has symmetrically opened heat-receiving grooves 53 on its upper and lower sides. The outer surface of the docking plate shell 51 is inserted into the inner wall of the heat-conducting frame 41. After the pre-pressed metallurgical powder is loaded into the interior of the docking plate shell 51, the docking plate shells 51 on both sides are joined together to form an insert plate body, which is inserted directly into the interior of the heat-conducting frame 41 to realize the feeding operation. Side insert plates 52 are symmetrically arranged on the left and right sides of the inner wall of the docking plate shell 51, and the outer surface of the docking plate shell 51 is inserted into the inner cavity of the card holder slide plate 44 through the side insert plates 52. The merged docking plate shell 51 is inserted into the inner cavity of the card holder slide plate 44 through the side insert plates 52 on both sides, so that the side push pressure plate 42 can push the docking plate shell 51 to perform a stable horizontal sliding movement, change the heated part of the docking plate shell 51, and achieve a uniform heating effect.

[0029] Pressure relief component 6 includes: The upper part of the filling box 61 is inserted into the side of the wall-mounted communicating shell 21, and the outer surface of the filling box 61 is snapped into the upper part of the inner wall of the heat insulation shell 11. The temperature-sensing top plate 62 is inserted into the top of the filling box 61 at its bottom. The top of the temperature-sensing top plate 62 is provided with a mating groove 63, and the top of the temperature-sensing top plate 62 is connected to the communicating groove of the heat insulation shell 11 through the mating groove 63.

[0030] Pressure relief component 6 also includes: The inner control board 64 has a temperature control chip 65 inserted into the front end of its inner cavity. The outer surface of the inner control board 64 is inserted into the bottom of the inner wall of the filling box 61 through the heat insulation layer. The inner control board 64 senses the actual temperature inside the heat insulation shell 11 through the temperature control chip 65. The connecting drum 7 is evenly inserted into the upper part of the inner control plate 64, which can connect the air inside the filling box 61 with the air inside the heat insulation shell 11. The outer surface of the connecting drum 7 is rotatably connected to the inner cavity of the filling box 61 through the rotating groove. The inner control plate 64 drives the connecting drum 7 to rotate axially through the micro motor in the inner cavity.

[0031] The connecting drum 7 includes: The bottom end of the vertical rotating cylinder 71 extends into the interior of the insulation layer of the filling box 61, and the bottom end of the vertical rotating cylinder 71 is inserted into the upper part of the inner control plate 64 through the rotating end. The two sides of the inner cavity of the vertical rotating cylinder 71 are symmetrically provided with through grooves. Mesh partitions 72 are symmetrically inserted into both sides of the inner cavity of the vertical rotating cylinder 71 through through slots. When either side of the mesh partitions 72 on both sides of the vertical rotating cylinder 71 is aligned with the outside of the filling box 61 through the rotating slot, the air inside the heat insulation shell 11 can dissipate heat to the outside of the heat insulation shell 11 through the docking slot 63 at the top. If the mesh partitions 72 are misaligned with the rotating slots, the rotating slots at this point are blocked. The inner filter plate 73 is located in the middle of the inner cavity of the vertical rotating cylinder 71 to filter the passing air.

[0032] When the outer casing 33 moves, the side-push pressure plates 42 located on both sides of the heat conduction frame 41 also control the pressure inside the compression connecting sleeve 43 and use the traction of the card holder slide plate 44 to drive the middle docking shell 51 to slide back and forth at a uniform speed along the inner wall of the card holder slide plate 44. This ensures that the flame of the flame nozzle 34 can completely cover the outer surface of the docking shell 51 through the groove of the heat conduction frame 41, thereby ensuring that the docking shell 51 is heated evenly.

[0033] During heat treatment inside the heat insulation shell 11, high pressure is generated due to high temperature. During prolonged operation, periodic pressure reduction is necessary to prevent production accidents. When the temperature control chip 65 inside the filling box 61 reaches its pressure threshold, the internal control board 64 is activated. The motor inside the internal control board 64 controls the deflection of the rotating drum 7, ensuring that the mesh partitions 72 of the vertical rotating drum 71 are aligned with the external slots of the filling box 61. At this point, the filling box 61 is in a pass-through state, allowing the high-temperature, high-pressure gas inside the heat insulation shell 11 to pass through the filling box 61. 1. The mating groove 63 of the temperature-sensing top plate 62 and the connecting groove on the top of the heat insulation shell 11 exchange heat with the outside, thereby achieving a pressure reduction effect. When the pressure is controlled, the inner control plate 64 can adjust the number of connecting drums 7 that block the slots of the filling box 61 by twisting the connecting drums 7, thereby achieving different pressure reduction effects of the pressure relief component 6. It can also completely block the filling box 61 in all vertical drum shell parts, so that the heat insulation shell 11 achieves a near-sealed effect, thereby improving the internal heat preservation effect and achieving the purpose of rapid heating.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
