Description

Technical Field

[0001] The present invention relates to the technical field of target material production, and in particular to an auxiliary device for sheath packaging and a packaging method. Background Art

[0002] High melting point metal targets are generally produced by hot isostatic pressing, which requires first making a sealed package filled with metal powder and evacuating it. Then the sealed package filled with metal powder is placed in a hot isostatic pressing device for hot isostatic pressing to make the metal powder in the package become a dense solid. Then the dense solid can be machined to obtain a target of the required size. The process of making a sealed package filled with metal powder is as follows: first put the metal powder into Figure 8 In the bag 4 shown in the figure, a powder filling tube 5 is provided on the top of the bag 4 (the powder filling tube 5 is welded on the bag 4, and there is no air leakage between the two, and the material of the powder filling tube 5 is generally Q235 or titanium, etc.), and the powder is loaded into the bag 4 through the powder filling tube 5. After the loading is completed, there is no powder in the powder filling tube 5 under the action of gravity and knocking; then a rubber tube is sleeved on the outside of the top of the powder filling tube 5 (the outside of the top of the powder filling tube 5 can be coated with vacuum silicone grease, which not only improves the reliability of the seal, but also improves the lubricity, making it easier to sleeve the rubber tube on the outside, and then the two can be fixed with a throat clamp to prevent the rubber tube from falling), and the other end of the rubber tube is connected to a vacuum pumping device to vacuum the bag 4; after the vacuum pumping is completed, the powder filling tube 5 needs to be packaged so that after the rubber tube is removed, the vacuum in the bag 4 will not be destroyed. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an auxiliary device for encapsulation and a packaging method for the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: an auxiliary device for wrapping packaging, including a bracket, a chopping board is arranged on the upper part of one side of the bracket, and also includes a movable frame, the movable frame includes a base plate, arm plates are arranged on both sides of the base plate, the two arm plates are respectively located on both sides of the chopping board and are slidably connected with the bracket, the base plate is located on the side of the bracket away from the chopping board, a through threaded hole is arranged on the base plate, a screw is connected to the threaded hole, a first socket and a second socket are arranged on the two arm plates, the height of the first socket is higher than the height of the second socket, the first socket and the second socket are located on the side of the bracket where the chopping board is arranged, and also includes a clamping plate for inserting into the two first sockets or the two second sockets.

[0005] To further optimize the technical solution, the cross-sections of the first jack and the second jack are rectangular.

[0006] To further optimize the technical solution, the two sides of the splint in the thickness direction are parallel to each other and are in contact with the two sides of the first plug hole or the two sides of the second plug hole respectively, and contraction parts are provided on both sides of the upper and lower parts of the splint.

[0007] To further optimize the technical solution, the second socket is located on a side of the first socket away from the bracket.

[0008] The method for packaging a package using the auxiliary device comprises the following steps:

[0009] S1. Soften the powder filling tube with flame and stick it on the side of the cutting board away from the bracket. Then use a hammer to flatten and compact the middle part of the powder filling tube to form a flattened part.

[0010] S2. Soften the part of the flattened portion at the same height as the top of the first insertion hole with a flame, then insert the splint into the first insertion hole on the two arm plates, and then rotate the screw rod so that the splint is attached to the side of the flattened portion away from the chopping board, and then bend the part of the flattened portion located above the splint downward so that the angle between the upper and lower parts of the flattened portion is less than 90°, and then pull out the splint, and then use a hammer to knock a section of the flattened portion that is bent down below the bending point in the direction of the flattened portion originally located below the bending point. The lower folding part is formed, and a section of the upper part of the lower folding part is attached to the flattened part originally located below the bending point; then the part of the lower folding part at the same height as the bottom of the second insertion hole is softened with a flame, and then the clamping plate is inserted into the second insertion holes of the two arm plates, and then the screw is rotated so that the clamping plate is attached to the side of the lower folding part away from the cutting board, and then the part of the lower folding part located below the clamping plate is bent upward to form an upper folding part, and then the clamping plate is pulled out, and then a section of the lower part of the upper folding part is knocked with a hammer to fit with the side of the lower folding part away from the cutting board;

[0011] S3. Then, use a neutral flame to burn the upper folding part from one side in the width direction of the upper folding part, and align the center of the flame with the middle in the thickness direction of the upper folding part. After this side of the upper folding part is burned and melted, most of the melted molten liquid will fall down under the action of gravity, so that this side of the upper folding part is disconnected from the burning point, and a small part of the melted molten liquid remains at the disconnection point at the top of the upper folding part. Then, gradually move the flame to the other side until the upper folding part is completely burned off. When the flame is removed, the molten liquid remaining at the disconnection point at the top of the upper folding part will solidify and weld the two sides of the place together to form a seal.

[0012] Compared with the prior art, the present invention has the following advantages: 1. A chopping board is arranged on the bracket, which is convenient for flattening the middle part of the powder filling tube to form a flattened part. A screw is threadedly connected to the base plate of the movable frame slidably connected to the bracket. After the clamp is inserted into the first insertion hole or the second insertion hole, tightening the screw can make the clamp stick to one side of the flattened part, so as to facilitate bending the flattened part. After the clamp is pulled out from the first insertion hole or the second insertion hole, the movable frame can be conveniently pushed so that the arm plate does not protrude from the chopping board, so as not to hinder the powder filling tube from being flattened with a hammer; 2. When the packaging sleeve is packaged, a lower folding part and an upper folding part are formed, so that the length of the flattened part left on the sleeve in the vertical direction is greatly reduced when the total length is long, and the top of the upper folding part forms a seal, which greatly improves the reliability of the seal.

The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0023] Example 1

[0024] Combination Figure 1-3 As shown, an auxiliary device for encapsulation includes a bracket 1, an anvil 11 is arranged on the upper part of one side of the bracket 1, and the side of the anvil 11 away from the bracket 1 is preferably perpendicular to the horizontal plane, and also includes a movable frame 3, the movable frame 3 includes a base plate 32, and arm plates 31 are arranged on both sides of the base plate 32, and the two arm plates 31 are respectively located on both sides of the anvil 11 and are slidably connected to the bracket 1, and two penetrating guide channels can be arranged on the bracket 1, and the two arm plates 31 are respectively slidably connected to the two guide channels, the base plate 32 is located on the side of the bracket 1 away from the anvil 11, and a penetrating threaded hole is arranged on the base plate 32, and the threaded hole is connected to a screw rod 2, and the screw rod 2 can be rotated to make it located on the base plate 32 close to the bracket 1 The length of one side changes, and the two arm plates 31 are both provided with a first socket 311 and a second socket 312. The height of the first socket 311 is higher than the height of the second socket 312. The first socket 311 and the second socket 312 are located on the side of the bracket 1 where the chopping board 11 is provided, and also include a clamp 33 for inserting into the two first sockets 311 or the two second sockets 312. The clamp 33 can be inserted into the two first sockets 311. After the clamp 33 is pulled out from the first socket 311, it can be inserted into the two second sockets 312, and the clamp 33 can also be placed aside. It is best that the clamp 33 cannot move up, down, left, and right relative to the first socket 311 or the second socket 312.

[0025] Furthermore, the cross-sections of the first plug hole 311 and the second plug hole 312 are rectangular.

[0026] Furthermore, the two sides of the clamp plate 33 in the thickness direction are parallel to each other and are in contact with the two sides of the first socket 311 or the two sides of the second socket 312 respectively. Contraction portions 331 are provided on both sides of the upper and lower portions of the clamp plate 33 so that a larger angle can be bent when the flattened portion 51 is bent.

[0027] Furthermore, the second insertion hole 312 is located on a side of the first insertion hole 311 away from the bracket 1 , and the distance between the second insertion hole 312 and the first insertion hole 311 is preferably not less than the sum of the thicknesses of the lower folded portion 511 and the upper folded portion 512 .

[0028] Example 2

[0029] Combination Figure 1-8 As shown, the method for packaging the package using the auxiliary device in Example 1 includes the following steps:

[0030] S1. Soften the powder filling tube 5 with a flame (oxyacetylene flame can be used) (for Q235 material, it should be burned red and then continue to burn until it is somewhat close to white, and the temperature at this time is above 1100°C), and then stick it to the side of the anvil 11 away from the bracket 1, and then use a hammer to flatten and pound the middle part of the powder filling tube 5 to form a flattened part 51. The powder filling tube 5 is a round tube, and the flattened part 51 formed after being flattened forms two layers in the middle, and the positions of the edges of the two sides of the two layers are combined together. After pounding, the two layers are tightly combined together, and basically achieve sealing;

[0031] S2. Soften the part on the flattening portion 51 at the same height as the top of the first insertion hole 311 with a flame, and then insert the clamping plate 33 into the first insertion hole 311 on the two arm plates 31. In order to prevent the movable frame 3 from interfering with the hammer to flatten the powder filling tube 5 in step S1, the end of the movable frame 3 provided with the first insertion hole 311 can be pushed toward the direction of the bracket 1 so that the arm plate 31 does not protrude from the anvil 11. Before inserting the clamping plate 33 into the first insertion hole 311, it is necessary to push the base plate 32 toward the direction of the bracket 1 so that the first insertion hole 311 is located on the side of the flattening portion 51 away from the anvil 11, and then rotate the screw 2 ( Figure 1 After the left end of the middle screw 2 is pressed against the bracket 1 and continues to rotate, the clamp 33 can be moved toward the direction close to the chopping board 11), so that the clamp 33 is attached to the side of the flattening portion 51 away from the chopping board 11, and then the flattening portion 51 located above the clamp 33 is bent downward, so that the angle between the upper and lower parts of the flattening portion 51 is less than 90°, and then the clamp 33 is pulled out (the screw 2 can be loosened first), and after the clamp 33 is pulled out, the movable frame 3 can be moved to Figure 1 The left end of the screw rod 2 leaves the bracket 1 for a certain distance, and then a hammer is used to knock a section of the flattened portion 51 below the bending point in the direction of the flattened portion 51 originally located below the bending point to form a lower folded portion 511, and a section of the upper part of the lower folded portion 511 is attached to the flattened portion 51 originally located below the bending point (due to the obstruction of the sleeve 4, the part of the lower folded portion 511 away from its top will be bent to a certain extent); then the part on the lower folded portion 511 at the same height as the bottom of the second insertion hole 312 is softened with a flame, and then the clamping plate 33 is inserted into the second insertion hole 312 on the two arm plates 31 (when the second insertion hole 312 is located on the side of the first insertion hole 311 away from the bracket 1 and the distance between the two is not less than the sum of the thicknesses of the lower folded portion 511 and the upper folded portion 512, there is no need to continue loosening the screw rod 2, and only needs to move the movable frame 3 to Figure 1The left side of the second insertion hole 312 can be pushed to the left side of the lower folding part 511, which is more convenient. Otherwise, the left end of the screw rod 2 will hit the bracket 1 before the second insertion hole 312 reaches the left side of the lower folding part 511), and then the screw rod 2 is rotated to make the clamping plate 33 stick to the side of the lower folding part 511 away from the anvil board 11, and then the part of the lower folding part 511 located below the clamping plate 33 is bent upward to form the upper folding part 512, and then the clamping plate 33 is pulled out, and then a section of the lower part of the upper folding part 512 is knocked with a hammer to make it fit with the side of the lower folding part 511 away from the anvil board 11. The fitting does not mean that they are combined together but are close to each other, or in other words, they are in contact. After the lower folding part 511 and the upper folding part 512 are formed, the flattened part 51 is folded, and it is generally believed that the sealing performance of the bending part is better because the outer side of the bending part is The inner side of the stretching is compressed, resulting in pressure between the two; it should be noted that when the flattening portion 51 is bent, the rubber tube is always sleeved on the end of the powder filling tube 5 to prevent the vacuum in the sheath 4 from being destroyed, and the other end of the rubber tube can be always connected to the vacuum equipment (the rubber tube should be relatively long, and its length should be much greater than the distance between the sheath 4 and the vacuum equipment), but this method is inconvenient, so the rubber tube can be designed into two sections, and the two sections are connected by a stainless steel tube, and the two ends of the stainless steel tube are respectively inserted into one end of the two sections. Before the bending and flattening portion 51, a section of the rubber tube connected to the powder filling tube 5 can be clamped with a specially designed clamp to seal the middle part, and then it can be pulled off the stainless steel tube. This section of the rubber tube can be shorter so that it will not be too much of a hindrance when the flattening portion 51 is bent.

[0032] S3, then use a neutral flame (oxyacetylene flame can be used, here use a neutral flame, not an oxidizing flame for cutting) to burn the upper folding portion 512 from one side in the width direction of the upper folding portion 512, and the burning position is selected at a certain distance above the lower folding portion 511 (generally about 20-30 mm above the lower folding portion 511), and the center of the flame is aligned with the middle of the thickness direction of the upper folding portion 512 (i.e., the middle of the two layers mentioned in step S1), so that the same positions of the two layers of the flattened portion 51 are melted at the same time (one layer will not be melted while the other layer is not melted, and the positions of the two layers melted at any point are not melted at the same time). The upper folding portion 512 is placed at substantially the same height, making it easier to weld together to form the seal 513 described later). After this side of the upper folding portion 512 is burned and melted, most of the melted liquid will fall down under the action of gravity, so that this side of the upper folding portion 512 is disconnected from the burning point, and a small amount of melted liquid remains at the disconnection point at the top of the upper folding portion 512. Then, the flame is gradually moved to the other side until the upper folding portion 512 is completely burned off. When the flame is removed, the melt remaining at the disconnection point at the top of the upper folding portion 512 will solidify and weld the two layers together to form the seal 513, and the packaging of the package 4 is completed. The seal 513 greatly improves the reliability of the seal.

[0033] The existence of the lower folded portion 511 and the upper folded portion 512 reduces the length of the flattened portion 51 remaining on the sheath 4 in the vertical direction a lot when the total length is long (the longer the total length, the higher the sealing reliability). Therefore, hot isostatic pressing equipment with a smaller high-pressure vessel height can be used during hot isostatic pressing.

[0034] It should be understood that the present application is not limited to the precise structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
