[0002] Tungsten-copper alloy is a composite material made by mixing tungsten and copper powders, pressing them into shape under high temperature and pressure, and finally sintering them. Due to its high density, good electrical conductivity, and high melting point, it is widely used in high-tech fields.

[0003] For related technologies, please refer to the Chinese patent with announcement number CN217465353U, which discloses a tungsten alloy sintering furnace with good temperature uniformity, including a heating tube, the four corners of the lower surface of the heating tube are fixedly connected to support legs, and slide grooves are provided on the left and right sides of the lower interior of the heating tube. A slide rod is provided inside the slide groove, and a placement tube is fixedly connected to one side of the slide rod. A second handle is fixedly connected to the middle of the front of the placement tube. A sealing mechanism is provided above the placement tube, and a stirring mechanism is provided inside the placement tube. The stirring mechanism includes a motor. The device is driven by a motor provided on the back of the heating tube, and the motor drives a rotating rod to rotate. The rotating rod passes through the middle of the back of the heating tube. The motor drives a stirring plate to rotate inside the heating tube through the rotating rod, stirring the tungsten alloy parts inside the heating tube, thereby achieving the effect of making the sintering furnace evenly heated during the heat treatment of the tungsten alloy.

[0004] Regarding the above-mentioned related technologies, after the tungsten-copper alloy parts are sintered, they need to be removed from the storage cylinder for dissolution or cold working. Because the parts are at a high temperature after sintering, workers need to use tools such as clamps to move and place the parts. When sintering parts in large quantities, batch removal and placement of parts takes a long time, making it inconvenient to remove the tungsten-copper alloy parts after sintering.

When the rotating motor drives the placement rack to rotate, the placement rack drives the corresponding placement cylinder to move through the support rod. In the initial state, the push rod is away from the placement cylinder under the action of the control member, and then the arc block 1 and the arc block 2 are driven to approach each other and engage with each other through the connecting rod. The tungsten-copper alloy is located in the gap between the arc block 1 and the arc block 2, so that when the placement cylinder moves, the tungsten-copper alloy is driven to move, and then the position of the tungsten-copper alloy is adjusted during sintering of the sintering cylinder. After sintering is completed, the sealing door is driven away from the sintering cylinder by the driving member. When the sealing door moves, the placement rack and all the placement cylinders are moved out of the sintering cylinder, and the placement rack is driven to rotate. When the placement cylinder moves to the lower end of the placement rack, the push rod is driven to approach the placement cylinder by the pushing member, so that the push rod drives the arc block 1 and the arc block 2 away from each other through the connecting rod, and then the tungsten-copper alloy is separated from the placement cylinder under the action of gravity, which is conducive to improving the convenience of taking out the tungsten-copper alloy.

[0009] Optionally, the driving component includes a moving motor, a driving screw, a moving block and a support frame.

Under the limiting action of the support frame, when the moving motor drives the driving screw, the driving screw moving block drives the sealing door to move, and then drives the placement rack to move through the sealing door, thereby improving the convenience of moving the sealing door and the moving rack.

[0011] Optionally, two parallel positioning rods are fixed to the lower end of the sealing door, the positioning rods are arranged along the length direction of the placement rack, and the sintering cylinder is provided with movable grooves adapted to the positioning rods along the length direction. The positioning rods are inserted into the corresponding movable grooves and are slidingly connected to the sintering cylinder. The sintering cylinder is rotatably connected to a number of support wheels along the length direction of the movable grooves, and the support wheels are rollingly connected to the positioning rods.

[0012] By adopting the above technical solution, the closing door drives the positioning rod to move when it moves, and the sintering cylinder supports the positioning rod through the moving groove and the supporting wheel, which is beneficial to improving the movement stability of the closing door and the moving frame.

[0014] By adopting the above technical solution, when the placement rack is located in the sintering cylinder, the connecting ring is sleeved on the outside of the rotating ring. When the placement rack drives the connecting ring to rotate, the rotating ring rotates with the connecting ring under the support of the positioning column, which is beneficial to improving the rotation stability of the placement rack.

[0015] Optionally, the swivel is fixedly connected to a plurality of guide blocks along the circumferential direction, and a plurality of slots adapted to the guide blocks are provided on the inner side of the connecting ring.

[0016] By adopting the above technical solution, when the guide block is inserted into the slot, the connecting ring limits the rotating ring through the cooperation between the guide block and the slot, which is beneficial to improving the connection stability between the connecting ring and the rotating ring.

[0017] Optionally, the control member includes a driving disk, a plurality of connecting rods and a plurality of elastic members, the elastic members corresponding to the support rods one-to-one for driving the push rods close to the placement cylinder, the plurality of connecting rods are evenly arranged along the circumference of the placement frame, and all push rods arranged along the axis direction of the support frame and in the same straight line correspond to the same connecting rod, the connecting rod is located at the end of the push rod away from the placement cylinder and contacts the push rod, the placement frame is fixedly connected to a positioning disk on the side close to the sealing door, the positioning disk is provided with an avoidance groove along the diameter direction, the driving disk is located between the sealing door and the positioning disk, and is slidingly connected to the sealing door along the axial direction, the sealing door is provided with a moving member for driving the driving disk to move, the positioning disk is located between all the connecting rods, and the width of the arc-shaped protrusion is smaller than the gap between two adjacent connecting rods.

[0018] By adopting the above technical solution, in the initial state, the driving disc is located near the sealing door. At this time, the driving disc and the connecting rod do not contact each other. The push rod is away from the placement cylinder under the action of the elastic member, so that the arc block 1 and the arc block 2 remain engaged. When it is necessary to separate the arc block 1 and the arc block 2, the driving disc is driven close to the positioning disc by the moving member. When the driving disc is between all the connecting rods, the placement rack is driven to rotate by the rotating motor. When the placement rack rotates, the connecting rod is driven to move circumferentially along the driving disc through the positioning disc. When the connecting rod collides with the arc protrusion along the driving disc, it moves away from the positioning disc axis along the avoidance groove under the guiding action of the arc protrusion. When the connecting rod moves, it pushes the corresponding push rod close to the placement cylinder, thereby driving the arc block 1 and the arc block 2 away from each other, thereby realizing the material removal of tungsten-copper alloy.

[0019] Optionally, the drive disk is provided with several mounting grooves along the circumference, and the arc-shaped protrusion is fixedly connected to a mounting block adapted to the mounting groove. The mounting block is inserted into the mounting groove and fits against the inner wall of the mounting groove.

[0024] 1. When sintering tungsten-copper alloy, the placement rack is located in the sintering cylinder, and the sealing door is driven by the driving member to seal the opening. When the rotating motor drives the placement rack to rotate, the placement rack drives the corresponding placement cylinder to move through the support rod. In the initial state, the push rod is away from the placement cylinder under the action of the control member, and then drives the arc block 1 and the arc block 2 to approach each other and engage with each other through the connecting rod. The tungsten-copper alloy is located in the gap between the arc block 1 and the arc block 2, so that when the placement cylinder moves, the tungsten-copper alloy moves, and then the position of the tungsten-copper alloy is adjusted during sintering of the sintering cylinder. After sintering is completed, the sealing door is driven away from the sintering cylinder by the driving member.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a tungsten-copper alloy sintering device.

[0035] Example:

[0036] Reference Figure 1 and Figure 2 A tungsten-copper alloy sintering device includes a sintering cylinder 1 with a rack 2 disposed therein. One end of the sintering cylinder 1 is open, and the rack 2 is provided with a sealing door 21 adapted to fit within the opening. The sealing door 21 is rotatably connected to the rack 2, and movement of the sealing door 21 drives the rack 2. The sintering cylinder 1 is provided with a drive element for driving the rack 2 and the sealing door 21.

[0037] Reference Figure 2 and Figure 3 The driving part includes a moving motor 31, a driving screw 32, a moving block 33 and a support frame 34. The support frame 34 is arranged along the axis of the sintering cylinder 1 and is fixed to the upper end of the sintering cylinder 1. Support legs 341 are fixedly connected to both ends of the support frame 34. The support legs 341 are arranged perpendicular to the support frame 34 and are used to support the support frame 34 and the sintering cylinder 1. A guide rail 342 is fixed to the lower end of the support frame 34 along the length direction. A guide wheel 25 adapted to the guide rail 342 is installed at the upper end of the sealing door 21. The guide wheel 25 is connected to the guide rail 342 in a rolling manner along the length direction. The support frame 34 guides the sealing door 21 through the cooperation between the guide rail 342 and the guide wheel 25, so that the sealing door 21 moves along the length direction of the guide rail 342.

[0038] Reference Figure 2 and Figure 3The movable block 33 is slidably connected to the guide rail 342 along its length. The support frame 34 limits the movable block 33 via the guide rail 342. The sealing door 21 is fixedly connected to the movable block 33. When the movable block 33 moves, the sealing door 21 moves. The drive screw 32 is arranged along the length of the guide rail 342 and passes through the movable block 33 and is threadedly connected to the movable block 33. Under the limit of the guide rail 342, the drive screw 32 rotates and drives the movable block 33 along the guide rail 342. The movable motor 31 is fixed to one end of the support frame 34. The output end of the movable motor 31 is coaxially fixed with the drive screw 32. When the movable motor 31 is in operation, it drives the drive screw 32 to rotate.

[0039] Reference Figure 3 and Figure 4 , two mutually parallel positioning rods 26 are fixed at the lower end of the sealing door 21, and the two positioning rods 26 are parallel to the guide rail 342. The sintering cylinder 1 is provided with a movable groove 11 adapted to the positioning rod 26 along the length direction, and the positioning rod 26 is inserted into the corresponding movable groove 11 and is slidably connected to the sintering cylinder 1. When the sealing door 21 moves, it drives the positioning rod 26 to move. The positioning rod 26 cooperates with the sintering cylinder 1 to support the sealing door 21, thereby improving the movement stability of the sealing door 21 and the placement rack 2. The sintering cylinder 1 is rotatably connected to a number of support wheels 12 along the length direction of the movable groove 11. When the positioning rod 26 moves, it is rolled and connected to the support wheel 12 in the corresponding limit groove. The provision of the support wheel 12 is conducive to reducing the friction between the positioning rod 26 and the sintering cylinder 1.

[0040] Reference Figure 3 and Figure 5 The placement rack 2 is circumferentially provided with a plurality of placement tubes 23. These tubes 23 include arc-shaped blocks 1 231 and 232, each of which is hollow on the side adjacent to the other. The placement rack 2 is circumferentially fixed with a plurality of support rods 24 corresponding to the placement tubes 23. The arc-shaped blocks 1 231 and 232 of the same placement tube 23 are hingedly connected to the support rods 24. Movement of the support rods 24 drives the corresponding arc-shaped blocks 1 231 and 232 to move. A push rod 241 is slidably connected to the support rods 24 along their length, and the sealing door 21 is provided with a control member for driving the push rod 241 to move. A connecting rod 242 is provided between the arc block 1 231 and the arc block 2 232 and the support rod 24. One end of the connecting rod 242 is hinged to the push rod 241, and the other end is hinged to the corresponding arc block 1 231 or the arc block 2 232. When the push rod 241 moves along the axial direction, the arc block 1 231 and the arc block 2 232 are driven to move closer to or away from each other through the connecting rod 242.

[0041] Reference Figure 3 and Figure 5The control component includes a driving disk 41, a plurality of connecting rods 42 and a plurality of elastic components 43. The elastic component 43 is a spring. One end of the spring is fixedly connected to the support rod 24, and the other end is fixedly connected to the push rod 241. The elastic component 43 drives the push rod 241 away from the placement tube 23. At this time, the arc block 1 231 and the arc block 2 232 are close to each other. When it is necessary to store tungsten-copper alloy in the placement tube 23, the push rod 241 is moved toward the placement tube 23, so that the push rod 241 drives the arc block 1 231 and the arc block 2 232 to separate from each other through the connecting rod 242.

[0042] Reference Figure 3 and Figure 5 All the connecting rods 42 are evenly arranged along the circumference of the placement rack 2 and are parallel to the placement rack 2. All the push rods 241 arranged along the axis direction of the placement rack 2 and located in the same straight line correspond to one connecting rod 42. The connecting rod 42 is located at the end of the push rod 241 away from the placement tube 23. When the connecting rod 42 moves in the direction away from the placement rack 2, it pushes all the push rods 241 in contact with it to approach the corresponding placement tube 23.

[0043] Reference Figure 3 and Figure 5 Positioning plates 28 are fixedly connected to both ends of the placement rack 2 along its length. These plates have diametrically defined escape slots 281 corresponding to the linkage rods 42. The linkage rods 42 pass through the corresponding escape slots 281 and slide along the length of the escape slots 281 to the positioning plates 28. The placement rack 2 and the positioning plates 28 cooperate to support the linkage rods 42. The drive plate 41 is located between the sealing door 21 and the positioning plates 28 and is slidably connected to the sealing door 21 along its axis. The sealing door 21 is equipped with a moving member for driving the drive plate 41.

[0044] Reference Figure 3 and Figure 6 The movable member includes a guide rod 51 and a movable lead screw 52. The guide rod 51 is arranged parallel to the placement rack 2 and is fixedly connected to the side of the sealing door 21 near the sintering cylinder 1. All guide rods 51 pass through the drive disk 41 and are slidably connected to the drive disk 41. The sealing door 21 guides and limits the drive disk 41 through the guide rods 51. The movable lead screw 52 is parallel to the guide rod 51 and passes through the sealing door 21 and is threadedly connected to the sealing door 21. When the movable lead screw 52 is rotated, the movable lead screw 52 moves along its own axis. One end of the movable lead screw 52 is rotatably connected to the drive disk 41, so that when the movable lead screw 52 rotates, it pushes the drive disk 41 toward or away from the positioning disk 28.

[0045] Reference Figure 2 and Figure 3The placement rack 2 is rotatably connected to the sealing door 21. A rotating motor 22 is fixed to the side of the sealing door 21 facing away from the sintering cylinder 1. A gear set is provided between the rotating motor 22 and the placement rack 2. When the rotating motor 22 is in operation, it drives the placement rack 2 to move through the gear set, which in turn drives the placement rack 2 to move all the placement cylinders 23. During the sintering process, the rotating motor 22 drives all the placement cylinders 23 to move, thereby adjusting the position of the tungsten-copper alloy and improving sintering uniformity.

[0046] Reference Figure 2 and Figure 3 The end of the placement rack 2 away from the sealing door 21 is fixedly connected to a connecting ring 27, and a positioning column 13 is fixedly connected to the sintering cylinder 1. The outer side of the positioning column 13 is rotatably connected to a rotating ring 14. During sintering, the connecting ring 27 is sleeved on the outer side of the rotating ring 14 and contacts the rotating ring 14. The support column supports the connecting ring 27 through the rotating ring 14. When the placement rack 2 drives the connecting ring 27 to rotate, the rotating ring 14 rotates with the connecting ring 27 under the support of the positioning column 13, which is beneficial to improve the rotation stability of the placement rack 2.

[0047] Reference Figure 2 and Figure 3 The swivel 14 is fixedly connected to a plurality of evenly spaced guide blocks 141 along its circumference. A slot 271 is defined on the inside of the connecting ring 27, which fits the guide blocks 141. The cross-sectional area of the guide blocks 141 along the axis of the connecting ring 27 gradually decreases as the swivel 14 points toward the sealing door 21. When the guide blocks 141 are inserted into the slots 271, the connecting ring 27 restrains the swivel 14 through the cooperation between the guide blocks 141 and the slots 271, thereby improving the stability of the connection between the connecting ring 27 and the swivel 14.

[0048] Reference Figure 2 and Figure 6 When sintering is completed, the placement rack 2 is removed from the sintering cylinder 1 by the driving member, and the movable screw 52 is rotated so that the movable screw 52 drives the driving disk 41 to approach the positioning disk 28. The driving disk 41 is provided with arc-shaped protrusions 411 along its circumference. The driving disk 41 is also provided with a plurality of mounting grooves 412 along its circumference. The arc-shaped protrusions 411 are fixed with mounting blocks 413. The mounting blocks 413 are inserted into the mounting grooves 412 and fit against the inner wall of the mounting grooves 412.

[0049] Reference Figure 2 and Figure 6 The mounting block 413 is provided with a fixing bolt 414, which passes through the mounting block 413 and is threadedly connected to the driving disk 41. Under the connection between the mounting slot 412 and the fixing bolt 414, when the driving disk 41 moves, the mounting block 413 is driven to move. Furthermore, the mounting block 413 can be installed in different mounting slots 412, thereby facilitating the adjustment of the position of the arc-shaped protrusion 411.

[0050] The implementation principle of a tungsten-copper alloy sintering device in an embodiment of the present application is as follows: the tungsten-copper alloy is located in the placement tube 23. When the tungsten-copper alloy needs to be taken out in batches, the placement rack 2 and all the placement tubes 23 are moved out of the sintering tube 1 through the driving member. When the push rod 241 moves, it drives the connecting rod 242 to move, so that the connecting rod 242 pushes the arc block 1 231 and the arc block 232 to separate from each other, so that the tungsten-copper alloy in the placement tube 23 is separated from the placement tube 23 under the action of gravity, which makes it more convenient to remove the tungsten-copper alloy in batches.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
