Description

Technical Field

[0001] This invention relates to the field of powder metallurgy technology, and in particular to a matching feeding device for inter-furnace turnover. Background Technology

[0002] In the field of metal powder injection molding, after the metal powder particles and binder are mixed to form a preform, it must be degreased in a degreasing furnace before it can be transferred to the sintering furnace for the next process. After injection molding, the preform formed from the mixture of metal powder particles and binder must be degreased in a specialized degreasing furnace (oxalic acid catalytic degreasing furnace or thermal degreasing furnace) before it can be transferred to the sintering furnace for high-temperature sintering. Traditional preform transfer processes are fragmented, involving numerous physical transfer steps, requiring significant manpower and time, and carrying the risk of preform falling and being damaged. For example, operators must first open the degreasing furnace door or sintering furnace door, remove the preform racks one by one, place them on the transfer tool, transport them to the sintering furnace, and then remove and load them into the sintering furnace one by one.

[0003] Therefore, how to provide a matching feeding device for the turnover between furnace bodies to improve the transfer efficiency of material plates between furnace bodies, the docking efficiency of material plates and furnace bodies, and reduce the loss rate of material plates during the transfer process is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to address the deficiencies and shortcomings of the prior art by providing a matching feeding device for the transfer between furnace bodies, thereby improving the transfer efficiency of material plates between furnace bodies, the docking efficiency between material plates and furnace bodies, and reducing the loss rate of material plates during the transfer process.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a feeding device for inter-furnace turnover. The feeding device includes a material cart and a material box slidably connected to the material cart. The bottom of the material box is provided with a sliding part. The cross-sectional dimension of the end face of the material box facing the degreasing furnace opening is smaller than the size of the degreasing furnace opening. The sliding part is used to slide on a slide rail inside the degreasing furnace. Multiple placement spaces are arranged from top to bottom inside the material box. The placement spaces are used to place material plates. The placement spaces correspond one-to-one with multiple storage spaces arranged in a sealed box inside the sintering furnace.

[0006] In one embodiment, the supporting feeding device includes a first locking assembly for locking the material box onto the material cart. The first locking assembly includes a first locking part and a second locking part. The first locking part is disposed on the material box, and the second locking part is disposed on the material cart. The first locking part and the second locking part are detachably connected.

[0007] In one embodiment, the supporting feeding device further includes a second locking assembly for locking the material box onto the degreasing furnace. The second locking assembly includes a third locking part and a fourth locking part. The third locking part is disposed on the material box, and the fourth locking part is disposed on the furnace body of the degreasing furnace. The third locking part and the fourth locking part are detachably connected.

[0008] In one embodiment, the supporting feeding device further includes a first guiding and positioning component, which includes a first guide member and a second guide member. The first guide member is provided on both sides of the material cart, and the second guide member is provided on both sides of the degreasing furnace at the positions of the first guide members. The first guide member and its corresponding second guide member slide and guide each other.

[0009] In one embodiment, the first guide member is a guide rod, the second guide member is a guide plate, the guide rods on both sides are located between the guide plates on both sides, and the guide rods slide in contact with the end faces of the guide plates near the guide rods.

[0010] In one embodiment, a guide roller is provided at one end of the guide rod near the degreasing furnace body, and the guide rod slides in cooperation with the guide plate through the guide roller.

[0011] In one embodiment, the supporting feeding device further includes a second guiding and positioning component, which includes a support frame and a V-shaped roller fixed on the support frame. The support frame is fixed on the material cart, and the V-shaped roller is connected to the cylinder positioning device of the sintering furnace. The second guiding and positioning component also includes a frame notch for embedding the support frame and the V-shaped roller, which is provided on the degreasing furnace.

[0012] In one embodiment, the material cart includes a movable body, an adjustment device, and a placement platform. The adjustment device is disposed between the movable body and the placement platform and is used to adjust the relative distance between the movable body and the placement platform.

[0013] In one embodiment, limit bars are provided on both sides of the sliding part corresponding to the slide rail. The limit bars are used to restrict the sliding part on the slide rail, and the distance between the two limit bars near the degreasing furnace opening gradually increases.

[0014] In one embodiment, the inner wall of the material bin is provided with multiple U-shaped shelf groups spaced apart from top to bottom, and the internal space of the U-shaped shelf groups and the space between adjacent U-shaped shelf groups are all placement spaces. The present invention achieves the following technical effects compared to the prior art: In this invention, the cross-sectional dimension of the end face of the material box facing the degreasing furnace opening is smaller than the size of the degreasing furnace opening, facilitating the material box's entry into the degreasing furnace. A cart containing material plates, positioned in its placement space, travels to the degreasing furnace opening, pushes the material box, and slides its sliding part into the furnace's internal track, allowing the material box to enter the degreasing furnace. This enables the material plates and material box to circulate between the cart and the degreasing furnace. After degreasing, the material box slides out from the furnace's internal track onto the cart via the sliding part. The cart then travels to the sintering furnace opening. At this point, the placement space within the cart corresponds one-to-one with the storage space within the sintering furnace's sealed box. Material plates from the cart's placement space can be placed one-to-one into the storage space within the sealed box, enabling the degreased material plates to circulate between the material box and the sealed box. Compared to traditional material plate transfer methods, the use of the feeding device in the degreasing and sintering processes improves the transfer efficiency of material plates between furnace bodies, the docking efficiency between material plates and the furnace body, and reduces the material plate loss rate during transfer.

Detailed Implementation

[0017] 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.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-7 As shown, the present invention provides a supporting feeding device for the turnover between furnace bodies. The feeding device includes a material cart 300 and a material box 200 slidably connected to the material cart 300. A sliding part 230 is provided at the bottom of the material box 200. The cross-sectional dimension of the end face of the material box 200 facing the furnace opening of the degreasing furnace 100 is smaller than the dimension of the furnace opening of the degreasing furnace 100. The sliding part 230 is used to slide on the slide rail 110 inside the degreasing furnace 100. Multiple placement spaces are arranged from top to bottom inside the material box 200. The placement spaces are used to place material plates. The placement spaces correspond one-to-one with the multiple storage spaces arranged in the sealed box inside the sintering furnace.

[0020] Understandably, the cross-sectional dimension of the end face of the material box 200 facing the furnace opening of the degreasing furnace 100 is smaller than the size of the furnace opening of the degreasing furnace 100, which facilitates the material box 200 entering the degreasing furnace 100. The material cart 300, which holds the material plates in its placement space, moves to the opening of the degreasing furnace 100 and pushes the material box 200. The sliding part 230 slides into the furnace track 370, and the material box 200 enters the degreasing furnace 100, realizing the turnover of the material plates and the material box 200 between the material cart 300 and the degreasing furnace 100. After degreasing, the material box 200 slides out from the furnace track 370 onto the material cart 300 through the sliding part 230. The material cart 300 moves to the sintering furnace opening. At this time, the placement space inside the material cart 300 corresponds one-to-one with the storage space inside the sintering furnace sealed box. The material plates in the placement space inside the material cart 300 can be placed one-to-one into the storage space inside the sealed box, realizing the turnover of the degreased material plates between the material box 200 and the sealed box. In the degreasing and sintering processes, the feeding device can improve the transfer efficiency of the material plates between the furnace bodies and the docking efficiency between the material plates and the furnace body, and reduce the loss rate of the material plates during the transfer process compared with the traditional material plate transfer method.

[0021] It should be noted that the material plate includes the raw material and the plate that supports the raw material; both the material cart 300 and the material box 200 can be equipped with pushers to facilitate the pushing of the material cart 300 and the material box 200; in order to ensure that the material cart 300 can be accurately connected with the degreasing furnace 100 and the sintering furnace, the height of the material cart 300, the degreasing furnace 100 and the sintering furnace need to be adjusted in advance so that the material cart 300 can be aligned with the degreasing furnace 100 and the sintering furnace; the material cart 300 is equipped with a track 370 that is adapted to the sliding part 230 to realize the sliding connection between the material box 200 and the material cart 300; a first baffle 111 is provided at the end of the slide rail away from the furnace opening of the degreasing furnace 100 to prevent the material cart 300 from continuing to move along the slide rail.

[0022] In one specific embodiment, the supporting feeding device includes a first locking component, which is used to lock the material box 200 onto the material cart 300. The first locking component includes a first locking part and a second locking part. The first locking part is disposed on the material box 200, and the second locking part is disposed on the material cart 300. The first locking part and the second locking part are detachably connected.

[0023] Understandably, the detachable connection between the first and second locking parts allows the material box 200 to be locked and unlocked on the material cart 300, preventing the material box 200 from swaying back and forth on the material cart 300 and causing damage to the material plate due to vibration. The first locking part can be a locking hole 210, and the second locking part can be a first pin assembly 310. The first pin assembly 310 is inserted into the locking hole 210 to lock the position of the material box 200; when the position is unlocked, the first pin assembly 310 is pulled out of the locking hole 210.

[0024] In one specific embodiment, the supporting feeding device further includes a second locking component, which is used to lock the material box 200 on the degreasing furnace 100. The second locking component includes a third locking part and a fourth locking part. The third locking part is disposed on the material box 200, and the fourth locking part is disposed on the furnace body of the degreasing furnace 100. The third locking part and the fourth locking part are detachably connected.

[0025] Understandably, the detachable connection between the third and fourth locking parts allows the material box 200 to be locked and unlocked on the degreasing furnace 100, preventing the material box 200 from detaching from the degreasing furnace 100. The third locking part can be a locking hole 210, and the fourth locking part can be a second pin assembly 120. Inserting the second pin assembly 120 into the locking hole 210 locks the material box 200 in position; when unlocking the position, the second pin assembly 120 is pulled out of the locking hole 210.

[0026] It should be noted that when both the first locking part and the third locking part are locking holes 210, the same locking hole 210 can simultaneously serve as both the first locking part and the third locking part. The second pin assembly 120 has the same structure as the first pin assembly 310. The second pin assembly 120 includes a base 121, a limiting protrusion 123, a pin rod 122, and a handle 124. There is a gap between the base 121 and the locking hole 210. The handle 124 is fixed to the pin rod 122, and the limiting protrusion 123 is fixed to the base 121. The limiting protrusion 123 cooperates with the handle 124 on the pin rod 122 to limit the sliding stroke of the pin rod 122 and provide two distinct physical positions for the pin rod 122: locked and unlocked. When the handle 124 drives the pin rod 122 to slide to a specific position, it will be locked by the limiting protrusion 123.

[0027] In use: The operator holds the handle 124 and pushes the pin 122 toward the material box 200, so that the conical head of the pin 122 is inserted into the locking hole 210. After the pin 122 is inserted into place, the groove on the pin 122 is engaged with the limiting protrusion 123 on the base 121 by rotating the handle 124 or by pushing and pulling directly. At this time, the pin 122 is fixed and cannot be retracted, i.e., it is in a locked state. When separation is required, the operator reverses the operation of the handle 124 to disengage the handle 124 of the pin 122 from the limiting protrusion 123, and then pulls the pin 122 out of the locking hole 210, so that the material box 200 can be removed.

[0028] In one specific embodiment, the supporting feeding device further includes a first guiding and positioning component, which includes a first guiding member and a second guiding member. The first guiding member is provided on both sides of the material cart 300, and the second guiding member is provided on both sides of the degreasing furnace 100 at the positions corresponding to the first guiding members. The first guiding member and its corresponding second guiding member slide and guide each other.

[0029] Understandably, the first guide member and its corresponding second guide member slide together to guide and restrict the movement direction and trajectory of the material cart 300, so that the material cart 300 and the degreasing furnace 100 can be accurately docked, and the material box 200 can slide directly from the material cart 300 into the degreasing furnace 100.

[0030] It should be noted that the material cart 300 needs to be equipped with a braking function in order to prevent the material cart 300 from sliding.

[0031] In one specific embodiment, the first guide member is a guide rod 320, the second guide member is a guide plate 130, and the two guide rods 320 are located between the two guide plates 130. The guide rods 320 and the end faces of the guide plates 130 near the guide rods 320 are in sliding engagement.

[0032] Understandably, the guide rod 320 and the guide plate 130 slide against each other at the end face near the guide rod 320. The guide plates 130 on both sides restrict the movement direction and trajectory of the guide rods 320 on both sides. The material cart 300 moves along the direction of the degreasing furnace 100, so that the material cart 300 and the degreasing furnace 100 can be accurately docked. The guide plate 130 can be an L-shaped plate, with the shorter plate fixed on the degreasing furnace 100 and the wider end face of the longer plate slidingly engaging with the guide rod 320 for guidance; the guide plate 130 can also be a long plate, with one end embedded in the degreasing furnace 100 and the other end protruding from the degreasing furnace 100, and the end face of the guide plate 130 near the guide rod 320 slidingly engaging with the guide rod 320 for guidance.

[0033] It should be noted that the first guide component can also be a guide post, and the second guide component can also be a guide sleeve. The guide post is inserted into the guide sleeve and slides with the guide sleeve to guide and limit the movement direction and trajectory of the material cart 300, so that the material cart 300 and the degreasing furnace 100 can be accurately docked.

[0034] In one specific embodiment, a guide roller 340 is provided at one end of the guide rod 320 near the furnace body of the degreasing furnace 100, and the guide rod 320 slides in cooperation with the guide plate 130 through the guide roller 340.

[0035] Understandably, the sliding engagement between the guide roller 340 and the guide plate 130 changes the friction mode from surface contact sliding friction to point or line contact rolling friction, reducing the coefficient of friction and making the pushing action under long distance and heavy load easy and smooth. The guide rollers 340 on both sides can also correct deviation. Even if the moving trajectory of the material cart 300 deviates slightly from the preset moving trajectory, the sliding engagement between the guide roller 340 and the guide plate 130 forces the end of the guide rod 320 to move along the path determined by the guide plate 130, ensuring the accuracy of the pushing endpoint.

[0036] In one specific embodiment, the supporting feeding device further includes a second guide and positioning component, which includes a support frame 330 and a V-shaped roller 321 fixed on the support frame 330. The support frame 330 is fixed on the material cart 300, and the V-shaped roller 321 is connected to the cylinder positioning device of the sintering furnace. The second guide and positioning component also includes a frame notch 140 for embedding the support frame 330 and the V-shaped roller 321. The frame notch 140 is provided on the degreasing furnace 100.

[0037] Understandably, the V-shaped roller 321 is connected to the cylinder positioning device of the sintering furnace. The cylinder positioning device includes a cylinder drive and a retractable V-shaped positioning block. When the material cart 300 is connected to the sintering furnace, the V-shaped positioning block locks the V-shaped roller 321 to achieve position locking. The frame notch 140 on the degreasing furnace 100 is embedded in the support frame 330 and the V-shaped roller 321 to prevent the second guide positioning component from restricting the movement distance of the material cart 300 and affecting the connection between the material cart 300, which is equipped with the second guide positioning component, and the degreasing furnace 100.

[0038] In one specific embodiment, the material cart 300 includes a movable cart body 350, an adjustment device 360, and a storage platform. The adjustment device 360 ​​is disposed between the movable cart body 350 and the storage platform, and is used to adjust the relative distance between the movable cart body 350 and the storage platform.

[0039] Understandably, a track 370 adapted to the sliding part 230 is set on the placement platform, and the adjustment device 360 ​​adjusts the relative distance between the movable vehicle body 350 and the placement platform so that the track 370 and the slide 110 are on the same horizontal plane and the track 370 and the slide 110 are horizontally connected, which facilitates the sliding of the material box 200 between the material cart 300 and the degreasing furnace 100.

[0040] It should be noted that the adjusting device 360 ​​can be an adjusting screw, one end of which is threadedly connected to the movable car body 350, and the other end of which is rotatably connected to the storage platform. The adjusting screw converts the rotational motion of the screw into linear lifting motion through the threaded joint, adjusting the height between the movable car body 350 and the storage platform. The adjusting device 360 ​​can also be an electric push rod or a servo electric cylinder, and is located at the four corners of the movable car body 350. The storage platform can be omitted, that is, the material cart 300 includes the movable car body 350, the adjusting device 360, and the sliding... The track 370 adapted to part 230 has an adjustment device 360 ​​positioned between the movable car body 350 and the track 370. The adjustment device 360 ​​is used to adjust the relative distance between the movable car body 350 and the track 370, allowing the track 370 to dock with the slide rail 110, facilitating the sliding of the material box 200 between the material cart 300 and the degreasing furnace 100. A second baffle 371 is provided at the end of the track 370 away from the second guide positioning component to prevent the material cart 300 from continuing to move along the track 370. A slide rail support 372 connects the two tracks 370 to improve structural stability. The movable car body 350 needs to have a braking function to facilitate stopping the movable car body 350 at a specific position, such as the position docked with the degreasing furnace 100 or the position docked with the sintering furnace.

[0041] In one specific embodiment, limit bars 112 are provided on both sides of the slide 110 corresponding to the sliding part 230. The limit bars 112 are used to restrict the sliding part 230 on the slide 110, and the distance between the two limit bars 112 near the furnace opening of the degreasing furnace 100 gradually increases.

[0042] Understandably, by using the appropriate gap between the limiting baffles 112 on both sides and the sliding part 230, the lateral swing freedom of the material box 200 is eliminated, allowing the material box 200 to slide smoothly along a fixed trajectory, reducing the probability of the material box 200 tipping over and the possibility of inertial impact on the material plate. At the entrance, the distance between the two limiting baffles 112 gradually increases to form a funnel shape. The sliding part 230 first contacts the inclined limiting baffles 112 at the funnel shape. Under the continued forward thrust, the component force of the inclined surface will gradually push the material box 200 back or guide it onto the preset movement trajectory of the slide rail 110, achieving smooth entry into the rail.

[0043] In one specific embodiment, the inner wall of the material box 200 is provided with multiple U-shaped shelf groups at intervals from top to bottom, and the internal space of the U-shaped shelf group and the space between adjacent U-shaped shelf groups are all placement spaces.

[0044] Understandably, a U-shaped shelf assembly consists of two U-shaped frames 220 with opposite openings arranged symmetrically. Multiple such U-shaped shelf assemblies are arranged at intervals from top to bottom on the inner wall of the material box 200, forming a vertical load-bearing array. The internal space of the U-shaped shelf assembly and the space between adjacent U-shaped shelf assemblies constitute the placement space. Compared with L-shaped frames, the U-shaped frame 220 is more labor-saving and material-saving.

[0045] The process flow of the feeding device between the degreasing furnace 100 and the sintering furnace: S1. Preliminary preparation: Adjust the center height of the degreasing furnace 100 and the sintering furnace to be consistent by adjusting the support feet at the bottom of the degreasing furnace 100 and the sintering furnace. The height of the material cart 300 is designed according to the center height of the degreasing furnace 100 and the sintering furnace, and the height is finely adjusted by adjusting device 360. S2. Loading of billet: The material cart 300 with empty material box 200 is braked and parked in the designated position. The locking hole 210 cooperates with the first pin assembly 310 to lock the material cart 300 in the fixed position. The material plate carrying the billet is inserted into the placement space formed by multiple U-shaped shelf groups of the material box 200 in sequence. S3. Feeding device positioning and docking with degreasing furnace 100: Push or pull the material cart 300 towards the furnace opening of degreasing furnace 100, so that the guide rods 320 on both sides of the material cart 300 are located between the guide plates 130 on both sides of degreasing furnace 100. Continue to push or pull the material cart 300 towards the furnace opening of degreasing furnace 100. The guide rods 320 and the guide plates 130 slide against the end face of the guide rods 320. The guide rollers 340 slide against the guide plates 130. When the material cart 300 moves to the track 370 and slides docks, brake and stop moving the material cart 300. At this time, the support frame 330 and the V-shaped rollers 321 are embedded in the frame notch 140. S4. Material box 200 is fed into degreasing furnace 100: the locking hole 210 and the first pin assembly 310 are released, and the material box 200 is pushed towards the furnace opening of degreasing furnace 100. Under the guidance of the limit stop bar 112, the material box 200 slides smoothly into degreasing furnace 100 until the material box 200 abuts against the first baffle 111. The material box 200 reaches the predetermined degreasing station. The third locking part and the second pin assembly 120 cooperate to lock the material cart 300 at the degreasing station. S5. Material box 200 removal and receiving: After sintering, release the locking of the third locking part and the second pin assembly 120, push the material box 200 onto the material cart 300 in the direction of the material cart 300, and lock the material cart 300 in the fixed position of the material cart 300 by the locking hole 210 and the first pin assembly 310. S6. Feeding device positioning and docking with sintering furnace: push or pull the material cart 300 towards the furnace opening of the sintering furnace, the V-shaped roller 321 docks with the cylinder positioning device of the sintering furnace, and brake to stop the moving material cart 300. S7. Transferring the material plate to the sintering furnace: After the sealing is completed, the outer door of the sintering furnace is opened, the locking hole 210 and the first pin assembly 310 are released, and the material box 200 is pushed towards the furnace opening. When the distance between the material box 200 and the sealing box is sufficient to transfer the material plate, the material box 200 is stopped. Another first pin assembly 310 (the first pin assembly 310 closer to the sintering furnace) cooperates with the locking hole 210 to lock the material cart 300 in the fixed position. The operator uses tools to smoothly slide the material plate in the placement space of the material box 200 into the corresponding placement space in the sealing box of the sintering furnace. After the material plate is transferred, the outer door of the sintering furnace is closed and sintering is carried out.

[0046] S8. Material box 200 removal and transfer unloading: The staff uses tools to smoothly slide the material plate in the storage space of the sealed box into the corresponding placement space in the material box 200. After the material plate is transferred, the locking hole 210 and the first pin assembly 310 are released, and the material box 200 is pushed away from the sintering furnace opening. When the material box 200 comes into contact with the second baffle 371, the movement of the material box 200 is stopped. The locking hole 210 and the first pin assembly 310 cooperate to lock the material cart 300 in the fixed position of the material cart 300. Push or pull the material cart 300 to the unloading position, and take out the material plates one by one from the placement space formed by the multiple U-shaped shelf groups of the material box 200 for product unloading and inspection.

[0047] S9. Post-processing preparation: Clean and inspect 200 material bins and 300 material carts.

[0048] This invention solves the problem of inaccurate docking between furnace bodies. The feeding device participates in the loading-degreasing-transfer-sintering-unloading process, which improves the transfer efficiency of the material plate between the furnace bodies and the docking efficiency between the material plate and the furnace body, and reduces the loss rate of the material plate during the transfer process.

[0049] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
