[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Traditional clamping and heat preservation devices often have complex clamping structures, high manufacturing and maintenance costs, and large size. Moreover, the limited space inside the vacuum induction melting furnace means that the entire device is located inside the furnace, which is not conducive to equipment layout.
[0024] In view of this, the present invention provides a clamping and heat preservation device for the membrane shell of a vacuum induction melting furnace. Through the cooperation of the cylinder, connecting plate, horizontal column, first T-shaped column, connecting plate, first sliding groove, second sliding groove, second T-shaped column and clamping shell, the membrane shell is clamped and heat-preserved. At the same time, it is easy to maintain, with a reasonable structural design, convenient installation and simple maintenance. It solves the problems of traditional clamping and heat preservation devices, which are mostly complex clamping structures, have high manufacturing and maintenance costs, large size, and limited space inside the vacuum induction melting furnace, resulting in the entire device being inside the furnace body, which is not conducive to equipment layout.
[0025] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.
[0026] Example 1, by Figure 1-4 As can be seen, the vacuum induction melting furnace film-coating and heat-preserving device in this case includes a vacuum furnace 1, a furnace cover 2 fixedly connected to the top of the vacuum furnace 1, a connecting plate 12 provided inside the vacuum furnace 1, a first sliding groove 14 and a second sliding groove 15 respectively opened on the surface of the connecting plate 12, a first T-shaped column 11 slidably engaged with the inner wall of the first sliding groove 14, and a clamping shell 17 rotatably connected to the outer wall of the first T-shaped column 11 through a bearing, wherein there are two clamping shells 17, and the tops of the two clamping shells 17 are attached to the connecting plate 12. At the bottom, the inner wall of each clamping housing 17 is provided with heat-insulating filler 18. A second T-shaped post 16 is fixedly connected to the top of the clamping housing 17 away from the first T-shaped post 11. The outer wall of the second T-shaped post 16 is slidably engaged with the inner wall of the second sliding groove 15. The clamping housing 17 has a semi-circular structure. The two clamping housings 17 are combined to form a circular clamping mechanism. There are two second T-shaped posts 16, which are respectively set on the clamping housing 17. The second sliding groove 15 is an arc-shaped groove to restrict the second T-shaped posts 16 from moving in a curved path.
[0027] In the specific implementation process, it is worth noting that the vacuum furnace 1 and the furnace cover 2 can be connected by bolts, which facilitates the disassembly and assembly of the furnace cover 2 by the staff. A sealing gasket can be set between the vacuum furnace 1 and the furnace cover 2. The sealing gasket is made of high-temperature resistant material, and the specific material is selected according to the actual situation. The staff opens the furnace cover 2, inserts the protective film shell into the interior of the vacuum furnace 1, and inserts the protective film shell into the through hole on the surface of the connecting plate 12. After that, the first T-shaped column 11 moves and slides in the first sliding groove 14. The first T-shaped column 11 moves the clamping housings 17 on both sides, which in turn moves the second T-shaped column 16. The second T-shaped column 16 slides in the second slide groove 15. Finally, the clamping housings 17 on both sides move the internal insulation filler 18 to clamp the column. After this is completed, the first T-shaped column 11 stops moving, and the insulation filler 18 blocks the gap between the clamping housing 17 and the insulation shell to prevent heat leakage. The insulation filler 18 is made of aluminum silicate fiber, which clamps and insulates the insulation shell.
[0028] Furthermore, a horizontal column 8 is fixedly connected to the lower outer wall of the first T-shaped column 11, and a connecting plate 7 is fixedly connected to the end of the horizontal column 8. A cylinder 5 is fixedly connected to the side wall of the connecting plate 7 by bolts, and the end of the cylinder 5 extends to the outside of the vacuum furnace 1.
[0029] In the specific implementation process, it is worth noting that the cylinder 5 is model SU50. The first T-shaped column 11 and the horizontal column 8 can be connected by bolts. The first T-shaped column 11 can be disassembled. After the protective film shell is inserted into the through hole on the surface of the connecting plate 12, the operator starts the cylinder 5. The cylinder 5 extends and drives the connecting plate 7 to move. The connecting plate 7 drives the horizontal column 8 to move. The horizontal column 8 then drives the first T-shaped column 11 to move. After clamping is completed, the operator stops the cylinder 5. When it is necessary to release the clamping, the cylinder 5 retracts, so that the clamping shells 17 on both sides move away from each other, releasing the clamping of the protective film shell, and realizing the movement of the first T-shaped column 11 driven by the cylinder 5.
[0030] Furthermore, a slider 9 is fixedly connected to the lower part of the horizontal column 8, and a slide rod 10 is slidably engaged with the inner wall of the slider 9. The end of the slide rod 10 is fixedly connected to the bottom of the inner wall of the vacuum furnace 1.
[0031] In the specific implementation process, it is worth noting that when the horizontal column 8 moves, the horizontal column 8 drives the slider 9 to move, and the slider 9 moves on the slide bar 10, thereby improving the stability of the movement of the horizontal column 8.
[0032] Furthermore, a curved plate 3 is fixedly connected to the side wall of the vacuum furnace 1, and a reinforcing plate 4 is fixedly connected between the curved plate 3 and the vacuum furnace 1. The end of the cylinder 5 is fixedly connected to the outer wall of the curved plate 3 by bolts.
[0033] In the specific implementation process, it is worth noting that while the curved plate 3 provides the mounting base for the cylinder 5, the reinforcing plate 4 can be arranged in a stable structure such as a triangle, which can increase the contact area between the curved plate 3 and the vacuum furnace 1 and improve the strength of the curved plate 3.
[0034] Furthermore, a sealing ring 6 is fixed to the side wall of the vacuum furnace 1, and the inner wall of the sealing ring 6 is attached to the outer wall of the output end of the cylinder 5.
[0035] In the specific implementation process, it is worth noting that the sealing ring 6 improves the sealing performance between the vacuum furnace 1 and the cylinder 5, which can effectively prevent gas leakage in the vacuum furnace 1 and ensure a stable vacuum environment. The sealing ring 6 is made of high-temperature resistant material, specifically fluororubber.
[0036] Example 2, by Figure 1 , 3 As can be seen from points 4, 5 and 6, the top of the clamping shell 17 is provided with a groove 21, the top of the thermal insulation filler 18 is provided with a recess 22, and the outer walls of the groove 21 and the recess 22 are respectively connected to insert blocks 20.
[0037] In the specific implementation process, it is worth noting that when the performance of the insulation filler 18 deteriorates after a period of use, the staff will disassemble the clamping shell 17, and then use external tools to remove the insert 20 from the recess 22. Finally, the staff will remove the insulation filler 18 inside the clamping shell 17, put the new insulation filler 18 into the inside of the clamping shell 17, and then re-insert the insert 20 into the inner wall of the groove 21 and the recess 22 in sequence to fix the new insulation filler 18, so as to facilitate the staff to replace the insulation filler 18.
[0038] Furthermore, vertical grooves 19 are respectively provided on the front and back of the clamping housing 17;
[0039] In the specific implementation process, it is worth noting that after the insert 20 is removed from the recess 22, the staff can insert an external tool into the interior of the vertical groove 19 and push the tool to push the degraded insulation filler 18 out of the clamping housing 17, so as to facilitate the staff to remove the degraded insulation filler 18.
[0040] Furthermore, a support column 13 is bolted to the bottom of the inner wall of the vacuum furnace 1, and the top of the support column 13 is bolted to the bottom of the connecting plate 12.
[0041] In the specific implementation process, it is worth noting that the support column 13 supports the connecting plate 12, thereby improving the stability of the clamping housing 17 during operation.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
