Description

Technical Field

[0001] This utility model relates to the field of dual-mode ceramic filter production technology, specifically to a dual-mode ceramic dielectric heat-shrink pressing tool. Background Technology

[0002] As the demands on communication products become increasingly stringent, dual-mode ceramic filters have successfully replaced traditional LC filter networks due to their stable performance requiring no adjustment and low cost. They possess high Q values, meaning excellent frequency response, along with good phase characteristics, compact size, and high signal-to-noise ratio, all of which have secured their important position in the communication market.

[0003] Currently, the traditional mechanical pressing process uses pressure to directly press the ceramic medium into the metal sleeve. Since the pressing between the ceramic and the metal sleeve is an interference fit, the high brittleness of the ceramic and the uneven temperature in the sintering furnace during the pressing process will make the sample surface rough, making it difficult to prepare ceramic media with precise shape tolerances. This leads to a series of problems such as ceramic medium breakage, edge collapse, and sleeve deformation during the pressing process. Utility Model Content

[0004] The purpose of this invention is to provide a dual-mode ceramic medium heat fitting tooling to solve the problem that the existing technology of directly using mechanical pressing easily leads to a low pressing pass rate.

[0021] As a preferred embodiment of the above technical solution, a hollow ring is fixedly connected to the end of the gooseneck tube away from the hollow cylinder, and a nozzle is fixedly connected to the inner wall of the hollow ring.

[0022] Through the above technical solution, by combining the fan, gooseneck tube, hollow ring and nozzle, airflow can be delivered to the surface of the metal sleeve to remove heat and improve the cooling rate.

[0023] As a preferred embodiment of the above technical solution, a copper pipe is fixedly connected between the top and bottom of the inner wall of the hollow cylinder, heat exchange fins are fixedly sleeved on the outer wall of the copper pipe, a second gate valve is fixedly connected to the top of the hollow cylinder, and a first gate valve is fixedly connected to the bottom of the hollow cylinder.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] like Figures 1-5 As shown, this utility model provides a technical solution: a dual-mode ceramic dielectric heat fitting tooling, comprising:

[0035] Workbench 1;

[0036] Positioning mechanism 2 is fixedly installed on the top of workbench 1. Positioning mechanism 2 is used to position the ceramic medium and the metal sleeve.

[0037] The pressing mechanism 3 is fixedly installed on the top of the workbench 1 and is used to press down the ceramic medium.

[0038] Cooling mechanism 4 is fixedly installed on the side of workbench 1 and is used to cool the metal sleeve.

[0039] As one implementation method in this embodiment, such as Figure 2 As shown, the positioning mechanism 2 includes a fixed block 21, which is fixedly installed on the top of the workbench 1. A track rod 22 is fixedly installed on the inner side of the fixed block 21. A movable seat 23 is slidably connected to the outer wall of the track rod 22. A fixing bolt 24 is threadedly connected to the front of the movable seat 23. The threaded end of the fixing bolt 24 is movably connected to the outer wall of the track rod 22. A positioning seat 25 is fixedly installed on the top of the movable seat 23. A threaded hole is opened on the top of the positioning seat 25. A threaded component 26 is detachably connected to the inner cavity of the threaded hole. A positioning block 27 is fixedly connected to the top of the threaded component 26. The preheated metal sleeve is placed on the outside of the positioning block 27, and the ceramic medium can be clamped on the top of the metal sleeve, completing the positioning work. Then, it can proceed... The positioning block 27 is threaded to the top of the positioning seat 25 via a threaded part 26 for easy operation. The operator can replace the positioning block 27 with different specifications to suit different specifications of ceramic media and metal sleeves. The top of the positioning seat 25 is provided with two positioning blocks 27 of different specifications. When the moving seat 23 is slid to the leftmost position on the track rod 22, the positioning block 27 on the right can be used for the pressing work. When the moving seat 23 is slid to the rightmost position on the track rod 22, the positioning block 27 on the left can be used for the pressing work. After the track rod 22 is slid into place, the fixing bolt 24 is tightened so that its threaded end fits against the outer wall of the track rod 22, thus completing the positioning of the positioning seat 25.

[0040] As one implementation method in this embodiment, such as Figure 3 As shown, the crimping mechanism 3 includes a stand 31, which is fixedly installed on the top of the workbench 1. A table plate 32 is fixedly installed on the front of the stand 31. A lead screw 33 is threadedly connected to the inner wall of the table plate 32. A pressure block 34 is rotatably connected to the bottom of the lead screw 33. A rotating wheel 35 is fixedly connected to the top of the lead screw 33. Manually rotating the rotating wheel 35 can drive the lead screw 33 to rotate on the table plate 32, thereby causing the lead screw 33 to move downward as a whole, and simultaneously driving the pressure block 34 to move downward. The pressure block 34 presses down on the ceramic medium, causing it to be stuck inside the metal sleeve.

[0041] As one implementation method in this embodiment, such as Figure 4 , Figure 5As shown, the cooling mechanism 4 includes a support sleeve 41, which is fixedly installed on the left side of the workbench 1. A hollow cylinder 42 is fixedly installed on the inner wall of the support sleeve 41. A fan 43 is fixedly connected to the bottom of the hollow cylinder 42, and a gooseneck tube 44 is fixedly connected to the top of the fan 43. A hollow ring 45 is fixedly connected to the end of the gooseneck tube 44 away from the hollow cylinder 42. A nozzle 46 is fixedly connected to the inner wall of the hollow ring 45. A copper tube 47 is fixedly connected between the top and bottom of the inner wall of the hollow cylinder 42. A heat exchange fin 48 is fixedly sleeved on the outer wall of the copper tube 47. A second gate valve 491 is fixedly connected to the top of the hollow cylinder 42, and a first gate valve 49 is fixedly connected to the bottom of the hollow cylinder 42. The gooseneck tube 44 is an existing structure. By bending it, the position of the hollow ring 45 can be flexibly adjusted, placing the hollow ring 45 on the outside of the metal sleeve. After the crimping work is completed, the fan 43 is controlled to work, which can absorb air and then transport it through the copper pipe 47 and gooseneck pipe 44 into the hollow ring 45. The air is then output from the nozzle 46 to the surface of the metal sleeve to cool the metal sleeve and improve production efficiency. If it is necessary to increase the cooling rate, the second gate valve 491 above can be opened to add low-temperature water into the inner cavity of the hollow cylinder 42. The low-temperature water can use the copper pipe 47 and heat exchange fins 48 to cool the flowing air inside the copper pipe 47, further improving the cooling effect. The first gate valve 49 is controlled to open, and the water that has been warmed up can be discharged.

[0042] Working principle: First, the metal sleeve is preheated. The preheated metal sleeve is then placed on the outside of the positioning block 27. The ceramic medium can then be clamped on the top of the metal sleeve to complete the positioning work. Then, the rotating wheel 35 is rotated, causing the lead screw 33 to move downward as a whole. The pressure block 34 presses down on the ceramic medium, clamping it inside the metal sleeve. The hollow ring 45 is pre-adjusted to the outside of the metal sleeve. After the pressing work is completed, the fan 43 is controlled to work, and air is output from the nozzle 46 to quickly cool the metal sleeve.

[0043] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
