Technical Field

[0001] This utility model relates to the technical field of sealing and air extraction devices, and in particular to a sealing and air extraction device for vacuum-rolled metal composite plates. Background Technology

[0002] Vacuum-sealed gas extraction device for multi-layer metal composite plate rolling is a core auxiliary equipment used in the multi-layer metal plate composite rolling process. It eliminates interlayer gas by creating a sealed cavity around the laminated plates and drawing a vacuum, thereby improving the bonding strength of the composite interface. This device typically consists of a sealing mechanism, extraction pipelines, a vacuum pump unit, and a control system. It must maintain a stable vacuum environment during the high-temperature, high-pressure rolling process, and its sealing performance directly affects the finished product quality and production efficiency of the composite plate.

[0003] Existing metal composite plate sealing and evacuation devices typically serve to evacuate vacuum chambers used in vacuum stacking. However, in actual use, the disassembly and assembly of the evacuation device and the vacuum chamber are relatively inconvenient, and the sealing performance at the disassembly and assembly ends is not good after installation, resulting in relatively insufficient airtightness and poor ease of use and performance. Therefore, we propose a vacuum stacking metal composite plate sealing and evacuation device to solve the above problems. Utility Model Content

[0028] The beneficial effects of this solution are as follows: The sealing mounting frame 21 on the sealing closure plate 2 can block and seal the disassembly and assembly holes on the vacuum stacking box wall 1, resulting in good sealing performance. The connection between the vacuum stacking box wall 1 and the sealing closure plate 2 is provided with a corresponding sealing mounting component 4, which can provide secondary sealing while facilitating disassembly and assembly. The vacuum extraction end 3 is installed and fixed on the sealing closure plate 2 and can be connected to the sealing mounting pipe 6. The vacuum extraction component 5 can perform vacuum extraction operations. The sealing mounting pipe 6 and the vacuum extraction end 3 can be sealed and fixed by the sealing fixing component 7, resulting in good tightness of the connection end. The two ends of the sealing fixing component 7 are connected by two auxiliary sealing sleeves 8 for auxiliary sealing, which further improves the airtightness of the installation. While maintaining airtightness, disassembly and assembly are simple and convenient, making the disassembly and assembly of the airtight equipment of the device relatively simple and convenient. It also has a double airtight sealing capability, excellent airtightness, and is not easy to leak.

[0029] Furthermore, a sealing mounting frame 21 is provided on the side of the sealing closure plate 2 away from the vacuum pumping end 3. The sealing mounting frame 21 is inserted into and press-fitted into the interior of the vacuum stacking box wall 1. The interior of the sealing mounting frame 21 is hollow.

[0030] Specifically, the disassembly and assembly holes on the wall 1 of the vacuum stacking box can be blocked and closed by the sealing and closing plate 2, and sealed and closed by the sealing and mounting frame 21 on the sealing and closing plate 2. The interior of the sealing and mounting frame 21 is hollow, with good air permeability and excellent adaptability.

[0031] Furthermore, the sealing installation assembly 4 includes a fitting mounting base 41, a matching sealing plate 42, a fixed lock cylinder 43, and a fixed latch 44. The fitting mounting base 41 is fixedly installed on the side of the vacuum stacking box wall 1 near the sealing closure plate 2. The matching sealing plate 42 is fixedly installed at the edge of the sealing closure plate 2 and is sealed and engaged with the fitting mounting base 41. Two fixed lock cylinders 43 are hingedly installed on the front and rear sides of the matching sealing plate 42 and are correspondingly installed on the vacuum stacking box wall 1. Two fixed latches 44 are respectively fastened and fixed to the two fixed lock cylinders 43.

[0032] Specifically, when the sealing closure plate 2 is installed on the vacuum stacking box wall 1, the matching sealing plate 42 provided at the edge of the sealing closure plate 2 can be attached to and sealed to the fitting mounting seat 41 on the vacuum stacking box wall 1. The matching sealing plate 42 is attached to and sealed to the fitting mounting seat 41, which plays a double sealing role and has excellent air tightness. The matching sealing plate 42 is hung on the fixed lock core 43 by the fixed buckle 44 on both sides, and is stably and conveniently installed on the vacuum stacking box wall 1, maintaining air tightness while being simple and convenient to disassemble and assemble.

[0033] Furthermore, the vacuum pumping assembly 5 is a vacuum pumping pump body.

[0035] Furthermore, the sealing and fixing assembly 7 includes a sealing sleeve tube 71 and an auxiliary threaded sleeve 72. One end of the sealing sleeve tube 71 is fixedly installed inside the sealing installation tube 6, and the other end of the sealing sleeve tube 71 is sealed and sleeved inside the tube body of the vacuum pumping end 3. The auxiliary threaded sleeve 72 is rotatably connected to the middle of the sealing sleeve tube 71, and the sealing sleeve tube 71 is threaded and sleeved on the outside of the vacuum pumping end 3.

[0036] Specifically, the sealing and fixing assembly 7 includes a sealing sleeve 71 and an auxiliary threaded sleeve 72. One end of the sealing sleeve 71 is fixed to the inside of the sealing installation tube 6. When the sealing installation tube 6 and the vacuum pumping end 3 are installed and fixed, the other end of the sealing sleeve 71 can be sealed and inserted into the vacuum pumping end 3, and then the auxiliary threaded sleeve 72 is threaded and fixed to the vacuum pumping end 3 to complete the sealing and fixing, which improves the airtightness of the connection between the sealing installation tube 6 and the vacuum pumping end 3. Both the sealing installation tube 6 and the vacuum pumping end 3 are provided with auxiliary sealing sleeves 8, and the two auxiliary sealing sleeves 8 are installed outside the auxiliary threaded sleeve 72 to play a secondary sealing and protection role, with excellent anti-loosening and airtight sealing capabilities.
