Abstract
Description
Technical Field
[0001] This utility model relates to the field of microwave and radio frequency circuit technology, and more specifically, it relates to a shaping fixture for cutting microwave absorbing materials to the size and shape. Background Technology
[0002] As microwave components develop towards miniaturization and high integration, their production tasks are increasingly characterized by short cycles and large batches. Microwave components need to have absorbing materials bonded inside to filter out clutter signals. Due to the limitations of the internal cavity structure, not only the main body of the component but also the inner cover plate needs to have absorbing materials bonded. The bonding position and size of the absorbing materials vary, so the required size and shape of the absorbing materials also vary.
[0003] Microwave absorbing material cutting involves cutting materials of different sizes and shapes from a single sheet of material measuring 305mm × 305mm × 1mm. Cutting methods are mainly divided into automatic cutting machines and manual cutting. Automatic cutting machines are expensive, while manual cutting helps reduce manufacturing costs. However, current manual cutting relies primarily on experience to estimate the approximate shape and size of the absorbing material from the sheet, followed by precise cutting to match the microwave components. This method has the following problems: First, the operational precision is low, resulting in inconsistent sizes and irregular shapes of the cut absorbing materials; second, the operational efficiency is low, as each cut requires first approximate sizes and shapes from a large sheet and then multiple cuts to meet precision requirements, impacting production progress; third, there is significant material waste, with substantial amounts of absorbing material wasted from cutting from large sheets.
[0004] Therefore, this application provides a shaping fixture for cutting the size and shape of microwave absorbing materials, thus solving the above-mentioned problems. Utility Model Content

[0028] Please see Figure 1 As shown, Figure 1 This is a structural diagram of a shaping fixture for cutting microwave absorbing materials to different sizes and shapes, provided in an embodiment of this application. The shaping fixture includes: a base 1 with a groove on its surface for fixing the microwave absorbing material; a shaping fixture main board 2 with multiple wire cutting grooves on its surface for cutting microwave absorbing materials of different sizes and shapes; and an auxiliary positioning handle 3 connected to the shaping fixture main board 2 for fixing the main board 2.
[0029] Specifically, the shaping fixture may include: a shaping fixture main board 2, two auxiliary positioning handles 3, and a base 1; the shaping fixture main board 2 has multiple wire cutting grooves, which are the cutting grooves for cutting the microwave absorbing material; the shaping fixture main board 2 is installed and fastened to the two auxiliary positioning handles 3, which provide a gripping part for manual operation; the groove on the upper part of the base 1 is used to place the whole sheet of microwave absorbing material to prevent the microwave absorbing material from moving during cutting.
[0030] During operation: Place a whole sheet of absorbing material in the groove of the shaping fixture base 1 for fixation; connect the shaping fixture main board 2 and the auxiliary positioning handle 3, and place them above the absorbing material; according to the required size of the absorbing material, use a scalpel to cut absorbing materials of different sizes and shapes through the wire cutting groove on the shaping fixture, and the cut absorbing materials can be pasted into the groove of the inner cover plate according to their size.
[0031] The improvement of this application is that it has a groove to prevent the absorbing material from moving during the cutting process; and it has a wire cutting groove to prevent the blade from slipping during the cutting process.
[0032] Please see Figure 2 As shown, Figure 2 This is a schematic diagram of the base 1 provided in an embodiment of this application. Figure 2 (a) is a front view of base 1. Figure 2 (b) is a side view of base 1. In one possible implementation, the size of the groove is adapted to the size of the absorbing material. Specifically, considering that the size of a whole sheet of absorbing material is typically 305mm × 305mm × 1mm, the length * width * height of the groove on the surface of base 1 can be set to 310mm * 310mm * 1mm, with a 2.5mm allowance on each side to accommodate dimensional errors of the whole sheet of absorbing material. The groove effectively fixes the whole sheet of absorbing material, preventing it from moving during cutting.
[0033] Please see Figure 3 As shown, Figure 3 This is a schematic diagram of the shaping fixture motherboard 2 provided in an embodiment of this application.

Specifically, a total of 6 through holes can be machined on the surface of the fixing area (counter-drilled holes are machined on the bottom surface), and two auxiliary positioning handles 3 are connected by 6 cross-slot countersunk screws. The triangular arrangement of through holes provides greater stability when connecting the auxiliary positioning handles 3.
[0038] Furthermore, the cutting area is evenly provided with multiple through holes for upgrading the fixture.
