Description

Technical Field

[0002] Titanium alloy injection molding is an advanced manufacturing process. It mixes titanium alloy powder with a binder and then performs injection molding. After degreasing and sintering, high-precision and high-strength titanium alloy parts are finally obtained. Among them, the titanium alloy powder billet is sintered in a sintering furnace, which can enable the billet to obtain the required physical and mechanical properties, such as hardness, strength, toughness, etc., thereby meeting the wide application needs of titanium alloy products.

[0003] When using the existing sintering furnace, the object frame containing the blanks is placed on the surface of the receiving plate, and then the receiving plate is placed in the sintering furnace to sinter the blanks. If the blanks are placed too densely, some blanks may be heated unevenly, thereby affecting the sintering effect. Therefore, in order to obtain a better sintering effect for the blanks, the blanks usually need to be placed separately. In some cases, the blanks to be sintered are spherical. In the prior art, when the spherical blanks are placed in the sintering furnace, the blanks are prone to rolling under the action of external force. When the spherical blanks roll, the blanks may fit together, thereby affecting the sintering effect.

The metal injection molding vacuum sintering furnace is provided with a threaded rod, a motor and a sliding rod, which can smoothly transport the workpiece to the inside of the vacuum sintering furnace body, so that the workpiece will not shake during transportation, thereby not changing the position of the workpiece, and thus not affecting the quality of the workpiece.

[0005] However, the above technical solution has the following defects: (1) The blanks are sintered by placing an object frame containing the blanks on the surface of a receiving plate, and then placing the receiving plate into a sintering furnace. If the blanks are placed too densely, some of the blanks may be heated unevenly, thereby affecting the sintering effect. Therefore, in order to obtain a better sintering effect, the blanks are usually placed separately. In some cases, the blanks to be sintered are spherical. In the above technical solution, when the spherical blanks are placed into the sintering furnace, the blanks are prone to rolling under the action of external force.

For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0032] As an improvement, Figure 1-Figure 8 As shown, the preferred embodiments of the present application are: A continuous sintering furnace for titanium alloy injection molding, comprising a sintering furnace body 1, a sliding plate 2 is slidably connected to one side of the inner cavity of the sintering furnace body 1, a support plate 23 is fixedly connected to the middle of both sides of the front and rear ends of the upper end surface of the sliding plate 2, a rotating frame 26 is rotatably arranged on one side of the upper end of the support plate 23, a receiving plate 3 is rotatably arranged in the middle of the rotating frame 26, and a plurality of downward pressing positioning mechanisms for placing spherical blanks are arranged on the receiving plate 3; The downward pressure positioning mechanism includes a plurality of placement seats 35 fixedly connected to the receiving plate 3, a plurality of positioning rods 39 are rotatably arranged on the placement seats 35, one end of the positioning rod 39 is fixedly connected to a guide column 40, a fixing rod 37 is fixedly connected to the middle of the lower end of the inner cavity of the placement seat 35, the fixing rod 37 is plugged and slidably connected to the pressure rod 36, a sliding sleeve 38 is sleeved and fixedly connected to the lower side of the pressure rod 36, a plurality of groove blocks 41 are fixedly connected around the outer circle of the sliding sleeve 38, and the guide column 40 is inserted into the groove of the groove block 41 and is slidably connected thereto.

[0033] Specifically, when the existing sintering furnace is in use, the object frame containing the blanks is placed on the surface of the receiving plate 3, and then the receiving plate 3 is placed in the sintering furnace to sinter the blanks. If the blanks are placed too densely, some blanks may be heated unevenly, thereby affecting the sintering effect. Therefore, in order to obtain a better sintering effect, the blanks need to be placed separately. In some cases, the blanks to be sintered are spherical. In the prior art, when the spherical blanks are placed in the sintering furnace, the blanks are prone to rolling under the action of external force. When the spherical blanks roll, the blanks may fit together, thereby affecting the sintering effect.

[0034] Therefore, in order to solve the above-mentioned problem, when this embodiment is used, the spherical blank to be sintered is placed on the upper end of the placement seat 35, and when the bottom of the spherical blank contacts the pressure rod 36, it will drive the pressure rod 36 to slide downward.

[0040] A worm wheel 24 is fixedly connected to one end of the front side of the rotating frame 26 . The worm wheel 24 is rotatably arranged on the front side support plate 23 . A worm 25 is rotatably arranged on the upper end of the front side support plate 23 . The worm 25 and the worm wheel 24 are meshed with each other.

[0041] A gear 30 is fixedly connected to the middle part of the lower end of the receiving plate 3, and the gear 30 is rotatably set on the rotating frame 26. A connecting plate 22 is fixedly connected to one side of the lower end surface of the blanking frame 4, and a sliding rod 28 is slidably connected to one side of the lower end of the connecting plate 22. A rack 29 is fixedly connected to the right end of the sliding rod 28, and the tooth block on the rack 29 is meshed with the gear 30. An electric push rod 27 is fixedly connected to one side of the left end surface of the connecting plate 22, and the piston end of the electric push rod 27 is fixedly connected to one side of the left end of the rack 29.

[0042] One end of the lifting plate 19 is threadedly connected to a threaded rod 3 17, both ends of the threaded rod 3 17 are rotatably set on the sintering furnace body 1, one side of the upper end of the sintering furnace body 1 is fixedly connected to a motor 2 16, the output end of the motor 2 16 is fixedly connected to the upper end of the threaded rod 3 17, one side of the left end face of the lifting plate 19 is fixedly connected to an electric push rod 3 20, and the piston end of the electric push rod 3 20 is fixedly connected to one side of the left end face of the unloading frame 4.

[0043] A sliding column 32 is slidably connected to one side of the left end of the blanking frame 4, a connecting rod 1 33 is rotatably provided at one end of the sliding column 32, and a connecting rod 2 34 is rotatably provided at one end of the connecting rod 1 33; a motor 31 is fixedly connected to one side of the left end of the blanking frame 4, and the output end of the motor 31 is fixedly connected to one end of the connecting rod 2 34.

[0044] Specifically, in the above embodiment, when manually placing multiple spherical blanks on the placement seat 35, it is time-consuming and laborious, which increases the labor intensity of the workers. Therefore, in order to avoid this problem, this embodiment is used for the same batch of spherical blanks with the same specifications, and the spherical blanks to be sintered are poured into the blanking frame 4 at one time. Moreover, since the blanks have been degreased before sintering, the degreased blanks have higher hardness and stability. Therefore, after the blanks are placed in the blanking frame 4, they will not become loose due to collision; then, according to the size of the blanks, the electric push rod 5 is used to drive the baffle 6 to move in the blanking frame 4 slides on one side, and under the cooperation of the material unloading frame 4 and the baffle 1 6, openings of different sizes are formed at the bottom of the material unloading frame 4, and this opening can only allow one billet to pass through, and then the motor 4 43 is used to drive the bidirectional threaded rod 42 to rotate, so that the adjustment plates 10 on both sides slide in different directions at the same time to adjust the distance between the two adjustment plates 10, so that the distance between the two adjustment plates 10 can only accommodate one billet. At this time, the billet will be arranged in the channel formed by the two adjustment plates 10 and the material unloading frame 4, and will be blocked by the baffle 29. Moreover, when the sliding plate 2 is outside the sintering furnace body 1, the gear 30 is in meshing state with the rack 29, and the electric push Rod four 27 drives rack 29 to move horizontally, so that gear 30 and receiving plate 3 rotate synchronously. When receiving plate 3 rotates, placement seat 35 will also rotate, and placement seat 35 will align with the end of the lower side of blanking frame 4. Then, according to the position of the gap between the two rightmost blanks, motor one 8 is used to drive threaded rod one 7 to rotate, so that adjustment frame 11 moves, so that spacer 14 is aligned with this gap, and electric push rod two 13 is used to drive spacer 14 to move, so that spacer 14 is inserted into the gap between the two blanks, so that the two blanks can be separated, and then motor five 44 is used to drive threaded rod two 15 to rotate, so that baffle two 9 slides downward until the blank can continue to slide downward. It will fall onto the placement seat 35 and be positioned by multiple positioning rods 39, then the baffle plate 2 9 and the spacer 14 are reset, and the above operations are repeated, multiple blanks can be placed on the placement seat 35 by intermittent rotation of the receiving plate 3 and intermittent dropping of the blanks from the bottom of the unloading frame 4, thereby realizing continuous and automatic placement of blanks of different sizes, eliminating the process of manually placing the blanks on the placement seat 35 one by one, which is more time-saving and labor-saving and reduces the labor intensity of workers. Then, the electric push rod 3 20 is used to drive the unloading frame 4 to move to the left, so that some structures such as the rack 29 will not affect the process of the sliding plate 2 entering the sintering furnace body 1.

[0045] However, when multiple blanks are in the blanking frame 4, the bottom opening of the blanking frame 4 may be blocked, thereby affecting the normal sliding of the blanks. Therefore, in order to avoid this situation, after the blanks are added to the blanking frame 4, the motor 31 is turned on to drive the connecting rod 2 34 to rotate, and the sliding column 32 is made to slide back and forth horizontally with the cooperation of the connecting rod 1 33. When the sliding column 32 slides horizontally, the blanks in the blanking frame 4 can be pushed, so that the blanks are always in a shaking state, thereby avoiding the situation where the bottom opening of the blanking frame 4 is blocked by the blanks, thereby affecting the normal sliding of the blanks.

[0046] Since the sintering process is a prior art, it will not be described in detail. When the blanks are sintered, the furnace door of the sintering furnace body 1 is opened, the sliding plate 2 is taken out from the sintering furnace body 1, and then the container for collecting the blanks is placed on the upper end of the sliding plate 2, and the worm gear 24 and the receiving plate 3 are rotated by rotating the worm 25, so that the receiving plate 3 can be turned over, and the blanks on the placement seat 35 will fall into the receiving container under the action of gravity, thereby realizing the collection of the blanks; and in some cases, the blanks need to be collected in batches to ensure that each receiving container has an appropriate amount of blanks for subsequent transportation, storage and other operations, and when all the blanks are dumped into the receiving container at one time, it is not conducive to the batching of the blanks, and it is also more laborious to manually put the blanks into the receiving container and distribute the quantity, which increases the labor intensity of the workers. Therefore, in order to solve the above problem, when the sliding plate 2 is removed from the sintering furnace body 1, the blanks are placed in the receiving container. After being moved out of the furnace body 1, the motor 2 16 is used to drive the threaded rod 3 17 to rotate, so that the material discharging frame 4 is lowered, and the electric push rod 3 20 is used to drive the material discharging frame 4 to move horizontally, so that the material discharging frame 4 is under the receiving plate 3. At this time, the receiving plate 3 is turned over again, and the blanks will fall into the material discharging frame 4 again, and the blanks will be arranged in the channel on the lower side of the material discharging frame 4. At this time, according to the number of blanks that need to be collected at one time, the position of the partition 14 is adjusted again to align it with the gap between two adjacent blanks, and the partition 14 is inserted into the gap again, and the containing container is placed at the end of the lower side of the adjusting plate 10. At this time, the baffle 2 9 is driven to descend again, and the blanks on the right side of the partition 14 will fall into the containing container, and the blanks on the left side of the partition 14 will be blocked. Then repeat the above operation, and different numbers of blanks can be dropped into the containing container according to actual needs, so as to facilitate subsequent transportation, storage and other operations of the blanks.

[0047] The working principle of the present application is as follows: for the same batch of billets with the same specifications, the spherical billets to be sintered are poured into the blanking frame 4 at one time, and because the billets have been degreased before sintering, the degreased billets have higher hardness and stability, so after the billets are placed in the blanking frame 4, they will not become loose due to collision; then, according to the size of the billets, the electric push rod 5 is used to drive the baffle 6 to slide on one side of the blanking frame 4, and with the cooperation of the blanking frame 4 and the baffle 6, openings of different sizes are formed at the bottom of the blanking frame 4, and this opening can only allow one billet to pass through at a time, and then the motor 43 is used to drive the bidirectional threaded rod 42 to rotate, so that the adjustment plates 10 on both sides are moved at the same time. The two adjusting plates 10 are slid in different directions at the same time to adjust the spacing between the two adjusting plates 10 so that the spacing between the two adjusting plates 10 can only accommodate one blank. At this time, the blanks are arranged in the channel formed by the two adjusting plates 10 and the blanking frame 4 and are blocked by the baffle 29. Moreover, when the sliding plate 2 is outside the sintering furnace body 1, the gear 30 is meshed with the rack 29, and the rack 29 is driven to move horizontally by the electric push rod 27 to make the gear 30 and the receiving plate 3 rotate synchronously. When the receiving plate 3 rotates, the placement seat 35 will also rotate, and the placement seat 35 will be aligned with the end of the lower side of the blanking frame 4. Then, according to the position of the gap between the two blanks on the far right, the motor 8 is used to drive the threaded rod 7 to rotate so that the adjusting frame 1 1 is moved to align the spacer 14 with the gap, and the electric push rod 2 13 is used to drive the spacer 14 to move so that the spacer 14 is inserted into the gap between the two blanks, so that the two blanks can be separated, and then the motor 5 44 is used to drive the threaded rod 2 15 to rotate, so that the baffle 2 9 slides downward until the blank can continue to slide downward, and the blank will fall onto the placement seat 35 and be positioned by multiple positioning rods 39, and then the baffle 2 9 and the spacer 14 are reset, and the above operation is repeated, and multiple blanks can be placed on the placement seat 35 by the intermittent rotation of the receiving plate 3 and the intermittent falling of the blanks from the bottom of the blanking frame 4. When the bottom of the spherical blank contacts the pressing rod 36, it will drive the pressing rod 36 to slide downward. When sliding downward, the sliding sleeve 38 and the groove block 41 will be synchronously lowered, so that the guide column 40 slides in the groove block 41, and the multiple positioning rods 39 rotate simultaneously until the end of the positioning rod 39 contacts the surface of the blank, thereby achieving the separation and positioning effect of the sintered spherical blanks to be sintered, thereby avoiding the situation where the blanks roll in the sintering furnace and the blanks are attached to each other, affecting the sintering effect, and eliminating the process of manually placing the blanks on the placement seat 35 in turn, which is more time-saving and labor-saving, and reduces the labor intensity of workers. Then, the electric push rod 20 is used to drive the unloading frame 4 to move to the left, so that the rack 29 and other partial structures will not affect the process of the sliding plate 2 entering the sintering furnace body 1;However, when multiple blanks are in the blanking frame 4, the bottom opening of the blanking frame 4 may be blocked, thereby affecting the normal sliding of the blanks. Therefore, in order to avoid this situation, after the blanks are added to the blanking frame 4, the motor 31 is turned on to drive the connecting rod 2 34 to rotate, and the sliding column 32 is made to slide back and forth horizontally with the cooperation of the connecting rod 1 33. When the sliding column 32 slides horizontally, the blanks in the blanking frame 4 can be pushed, so that the blanks are always in a shaking state, thereby avoiding the situation that the blanks block the bottom opening of the blanking frame 4, thereby affecting the normal sliding of the blanks; since the sintering process is an existing The technology is not described in detail. When the sintering of the blank is completed, the furnace door of the sintering furnace body 1 is opened, the sliding plate 2 is taken out of the sintering furnace body 1, and then the container for collecting the blank is placed on the upper end of the sliding plate 2. By rotating the worm 25, the worm wheel 24 and the receiving plate 3 are rotated, so that the receiving plate 3 can be turned over, and the blank on the placement seat 35 will fall into the receiving container under the action of gravity, thereby realizing the collection of the blank; and in some cases, the blank needs to be collected in batches to ensure that each receiving container has an appropriate amount of blanks for subsequent transportation, storage and other operations, and when all When the blanks are poured into the holding container at one time, it is not conducive to batching the blanks. It is also laborious to manually put the blanks into the holding container and distribute the quantity, which increases the labor intensity of the workers. Therefore, in order to solve the above problem, after the sliding plate 2 is moved out of the sintering furnace body 1, the motor 2 16 is used to drive the threaded rod 3 17 to rotate, so that the unloading frame 4 is lowered, and the electric push rod 3 20 is used to drive the unloading frame 4 to move horizontally, so that the unloading frame 4 is under the receiving plate 3. At this time, the receiving plate 3 is turned over again, and the blanks will fall into the unloading frame 4 again, and the blanks are arranged in At the channel below the unloading frame 4, at this time, according to the number of blanks to be collected at one time, adjust the position of the spacer 14 again to align it with the gap between two adjacent blanks, and insert the spacer 14 into the gap again, and place the container at the end of the lower side of the adjustment plate 10. At this time, drive the baffle 2 9 down again, and the blanks on the right side of the spacer 14 will fall into the container, and the blanks on the left side of the spacer 14 will be blocked, and then repeat the above operation, and different numbers of blanks can be dropped into the container according to actual needs, so as to facilitate the subsequent transportation and storage of the blanks. ;
