Description

Technical Field

[0001] This invention relates to the field of target production technology, and in particular to an auxiliary device and packaging method for encapsulation. Background Technology

[0002] High-melting-point metal targets are generally produced using hot isostatic pressing (HIP). This requires first creating a sealed casing containing metal powder and then subjecting it to vacuum treatment. The sealed casing containing the metal powder is then placed in a HIP apparatus for hot isostatic pressing, causing the metal powder inside to become a dense solid. This dense solid can then be machined to obtain the target material of the required size. The process of creating the sealed casing containing the metal powder is as follows: first, the metal powder is loaded into… Figure 8 In the sleeve 4 shown, a powder filling tube 5 is provided at the top of the sleeve 4 (the powder filling tube 5 is welded to the sleeve 4, and the two are airtight; the material of the powder filling tube 5 is generally Q235 or titanium, etc.). Powder is filled into the sleeve 4 through the powder filling tube 5. After filling, under the action of gravity and tapping, there is no powder in the powder filling tube 5. Then, a rubber tube is used to cover the outside of the top of the powder filling tube 5 (vacuum silicone grease can be applied to the outside of the top of the powder filling tube 5, which improves the reliability of the seal and the lubrication, making it easier to cover the outside of the rubber tube; then, a hose clamp can be used to fix the two to prevent the rubber tube from falling off). The other end of the rubber tube is connected to a vacuum pump to evacuate the sleeve 4. After the vacuum is completed, the powder filling tube 5 needs to be sealed so that the vacuum inside the sleeve 4 will not be broken after the rubber tube is removed. Summary of the Invention

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

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an auxiliary device for packaging, including a bracket, an anvil board is provided on the upper part of one side of the bracket, and a movable frame is also included. The movable frame includes a base plate, and arm plates are provided on both sides of the base plate. The two arm plates are respectively located on both sides of the anvil board and slidably connected to the bracket. The base plate is located on the side of the bracket away from the anvil board. A through threaded hole is provided on the base plate, and a screw is connected to the threaded hole. A first insertion hole and a second insertion hole are provided on both arm plates. The height of the first insertion hole is higher than the height of the second insertion hole. The first insertion hole and the second insertion hole are located on the side of the bracket where the anvil board is provided. The device also includes a clamping plate for inserting into the two first insertion holes or the two second insertion holes.

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

[0006] To further optimize this technical solution, the two sides of the clamping plate in the thickness direction are parallel to each other and the two sides respectively contact the two sides of the first insertion hole or the two sides of the second insertion hole. The upper and lower sides of the clamping plate are provided with shrinkage portions.

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

[0008] The method for encapsulating a package using the aforementioned auxiliary device includes the following steps:

[0009] S1. After softening the powder filling tube with a flame, stick it to the side of the cutting board away from the support. 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 flattened portion at the same height as the top of the first insertion hole with a flame. Then insert the clamp into the first insertion hole on both arm plates. Turn the screw so that the clamp is against the side of the flattened portion away from the anvil. Then bend the portion of the flattened portion above the clamp downwards so that the angle between the upper and lower parts of the flattened portion is less than 90°. Then remove the clamp. Finally, use a hammer to strike the section of the flattened portion below the bending point in the direction where the flattened portion was originally located below the bending point. The lower fold is formed, and a section of the upper part of the lower fold is attached to the flattened part that was originally located below the bending point; then the part of the lower fold that is at the same height as the bottom of the second insertion hole is softened by flame; then the clamp is inserted into the second insertion hole on the two arm plates; then the screw is turned so that the clamp is attached to the side of the lower fold away from the anvil; then the part of the lower fold located below the clamp is bent upward to form the upper fold; then the clamp is pulled out; then a hammer is used to strike a section of the lower part of the upper fold so that it is attached to the side of the lower fold away from the anvil.

[0011] S3. Then, use a neutral flame to burn the upper fold from one side in the width direction of the upper fold, with the center of the flame aligned with the middle in the thickness direction of the upper fold. After this side of the upper fold is melted, most of the melted liquid will fall under the action of gravity, causing this side of the upper fold to break off from the burning point. A small portion of the melted liquid will remain at the break at the top of the upper fold. Then, gradually move the flame to the other side until the upper fold is completely burned off. When the flame is removed, the melt remaining at the break at the top of the upper fold will solidify and weld the two sides together to form a seal.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The support is provided with an anvil, which makes it easy to flatten the middle part of the powder filling tube to form a flattened part. The movable frame, which is slidably connected to the support, has a screw threaded on its base plate. After the clamp is inserted into the first or second insertion hole, tightening the screw can make the clamp stick to one side of the flattened part, thereby making it easy to bend the flattened part. After the clamp is pulled out from the first or second insertion hole, the movable frame can be easily pushed so that the arm plate does not protrude from the anvil, thus not hindering the use of a hammer to flatten the powder filling tube; 2. When sealing the sleeve, a lower fold and an upper fold are formed, which greatly reduces the length of the flattened part left on the sleeve in the vertical direction when the total length is long. The top of the upper fold forms a seal, which greatly improves the reliability of the seal. Attached Figure Description

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0023] Example 1

[0024] Combination Figure 1-3 As shown, an auxiliary device for packaging includes a support 1. An anvil 11 is disposed on the upper part of one side of the support 1. The side of the anvil 11 away from the support 1 is preferably perpendicular to the horizontal plane. The device also includes a movable frame 3, which includes a base plate 32. Arm plates 31 are disposed on both sides of the base plate 32. The two arm plates 31 are located on opposite sides of the anvil 11 and are slidably connected to the support 1. Two through-hole guide channels can be provided on the support 1, and the two arm plates 31 are slidably connected to the two guide channels. The base plate 32 is located on the side of the support 1 away from the anvil 11. A through-hole threaded hole is provided on the base plate 32, and a screw 2 is connected to the threaded hole. Rotating the screw 2 allows it to be positioned closer to the support 1 on the base plate 32. The length of one side changes. Both arm plates 31 are provided with a first insertion hole 311 and a second insertion hole 312. The height of the first insertion hole 311 is higher than the height of the second insertion hole 312. The first insertion hole 311 and the second insertion hole 312 are located on the side of the bracket 1 where the anvil 11 is provided. It also includes a clamping plate 33 for inserting into the two first insertion holes 311 or the two second insertion holes 312. The clamping plate 33 can be inserted into the two first insertion holes 311. After the clamping plate 33 is pulled out from the first insertion hole 311, it can be inserted into the two second insertion holes 312. The clamping plate 33 can also be placed aside. It is best that the clamping plate 33 cannot move up, down or left and right relative to the first insertion hole 311 or the second insertion hole 312.

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

[0026] Furthermore, the two sides of the clamping plate 33 in the thickness direction are parallel to each other and the two sides respectively contact the two sides of the first insertion hole 311 or the two sides of the second insertion hole 312. The upper and lower sides of the clamping plate 33 are provided with contraction portions 331, so that a larger bending angle can be achieved when bending and flattening the portion 51.

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

[0028] Example 2

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

[0030] S1. Soften the powder filling tube 5 with a flame (oxy-acetylene flame can be used) (for Q235 material, it should be heated until it is red-hot and then continued to be heated until it is almost white, at a temperature above 1100℃). Then stick it to the side of the cutting board 11 away from the support 1. Then use a hammer to flatten and compact the middle part of the powder filling tube 5 to form a flattened part 51. The powder filling tube 5 is a round tube. After being flattened, the flattened part 51 formed has two layers in the middle. The two edges of the two layers are joined together. After being compacted, the two layers are tightly joined together, which basically achieves a seal.

[0031] S2. Soften the flattened portion 51, which is at the same height as the top of the first insertion hole 311, with a flame. Then insert the clamping plate 33 into the first insertion holes 311 on the two arm plates 31. To prevent the moving frame 3 from obstructing the hammering of the powder filling tube 5 in step S1, the end of the moving frame 3 with the first insertion hole 311 can be pushed towards the support 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, the base plate 32 needs to be pushed towards the support 1 so that the first insertion hole 311 is located on the side of the flattened portion 51 away from the anvil 11. Then rotate the screw 2 ( Figure 1 After the left end of the screw 2 rests on the bracket 1, continued rotation can move the clamp 33 closer to the cutting board 11, so that the clamp 33 is attached to the side of the flattened part 51 away from the cutting board 11. Then, bend the part of the flattened part 51 above the clamp 33 downwards, so that the angle between the upper and lower parts of the flattened part 51 is less than 90°. Then pull out the clamp 33 (the screw 2 can be loosened a little first). After pulling out the clamp 33, the movable frame 3 can be moved towards... Figure 1 Push the right side of the screw 2 a certain distance (at this time, the left end of the screw 2 leaves the bracket 1), and then use a hammer to strike a section of the flattened part 51 below the bending point in the direction of the flattened part 51 that was originally located below the bending point to form a lower fold 511. The upper part of the lower fold 511 is attached to the flattened part 51 that was originally located below the bending point (due to the obstruction of the sleeve 4, the part of the lower fold 511 away from its top will bend to a certain extent). Then, the part of the lower fold 511 that is at the same height as the bottom of the second insertion hole 312 is softened by flame. Then, insert the clamp 33 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 thickness of the lower fold 511 and the upper fold 512, there is no need to continue to loosen the screw 2. Just move the moving frame 3 towards Figure 1Pushing the left side of the screw 2 will position the second insertion hole 312 to the left of the lower fold 511, which is more convenient. Otherwise, the left end of the screw 2 will hit the bracket 1 before the second insertion hole 312 reaches the left side of the lower fold 511. Then, rotate the screw 2 so that the clamp 33 is attached to the side of the lower fold 511 away from the anvil 11. Then, bend the part of the lower fold 511 below the clamp 33 upward to form the upper fold 512. After that, pull out the clamp 33 and use a hammer to strike the lower part of the upper fold 512 to make it fit together with the side of the lower fold 511 away from the anvil 11. The fitting is not a complete joining but rather a close contact. After the lower fold 511 and the upper fold 512 are formed, the flattened part 51 is folded. It is generally believed that the sealing at the bend is better because the outside of the bend is... The compression of the inner side during stretching creates pressure between the two. It should be noted that when bending and flattening part 51, the rubber tube is always fitted over the end of the powder filling tube 5 to prevent the vacuum inside the sleeve 4 from being broken. The other end of the rubber tube can be connected to the vacuuming equipment (the rubber tube should be relatively long, and its length should be much greater than the distance between the sleeve 4 and the vacuuming equipment). However, this method is inconvenient. Therefore, the rubber tube can be designed into two sections, which are connected by a stainless steel tube. The two ends of the stainless steel tube are inserted into one end of each of the two sections. Before bending and flattening part 51, the section of rubber tube connected to the powder filling tube 5 can be clamped with a specially designed clamp to seal the middle, and then it can be pulled off the stainless steel tube. This section of rubber tube can be relatively short so that it will not be too obstructive when bending and flattening part 51.

[0032] S3. Next, use a neutral flame (an oxyacetylene flame can be used, but a neutral flame is used here instead of the oxidizing flame used for cutting) to scorch the upper fold 512 from one side of its width direction. The scorching position is selected at a certain distance above the lower fold 511 (generally about 20-30 mm above the lower fold 511). The center of the flame is aligned with the middle of the upper fold 512 in its thickness direction (i.e., the middle of the two layers mentioned in step S1), so that the same positions of the two layers of the flattened part 51 melt at approximately the same time (it will not be that one layer melts while the other layer has not yet melted, and the melting position of the two layers at any point is...). (By placing the components at roughly the same height, making the subsequent welding to form the seal 513 easier), after melting this side of the upper fold 512, most of the molten material will fall under the influence of gravity, causing this side of the upper fold 512 to break off from the burning point. A small portion of the molten material remains at the break at the top of the upper fold 512. Then, the flame is gradually moved to the other side until the upper fold 512 is completely burned off. After the flame is removed, the molten material remaining at the break at the top of the upper fold 512 will solidify, welding the two layers together to form the seal 513. The encapsulation of the sleeve 4 is complete. The seal 513 significantly improves the reliability of the seal.

[0033] The presence of the lower fold 511 and the upper fold 512 reduces the length of the flattened portion 51 remaining on the sleeve 4 in the vertical direction when the total length is relatively long (the longer the total length, the higher the reliability of the seal). Therefore, a hot isostatic pressing device with a smaller height can be used in hot isostatic pressing.

[0034] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
