Technical Field

[0001] The utility model relates to the technical field of wire cutting devices, in particular to a wire cutting device for antenna production. Background Art

[0002] Antennas are the main media for transmitting and receiving electromagnetic waves. They transform guided waves propagating on transmission lines into electromagnetic waves propagating in unbounded media, or perform the opposite transformation. They are often used in engineering systems such as communications, broadcasting, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy. Antennas need to be cut during production.

[0025] In this embodiment, in order to automatically fix the antenna during the wire cutting process, the antenna body 8 is placed on the top of the two rotating wheels 7 during wire cutting, so that the antenna body 8 is at the top of the trapezoidal block 4 and contacts the trapezoidal block 4. When the hydraulic cylinder 9 is started, the hydraulic cylinder 9 causes the push rod 10 to move downward, and the push rod 10 moves through the cutter mounting seat 11 to move the cutter 12 downward. At the same time, when the push rod 10 moves, the wire cutting and pressing unit is moved synchronously through the connecting plate 13. When the anti-slip pad 18 contacts the antenna body 8, the pressing plate 17 stops moving to pre-fix the antenna body 8. At this time, the connecting plate 13 continues to move downward, and the pressure on the antenna body 8 increases, and the antenna body 8 is gradually pressed. Then the cutter 12 contacts the antenna body 8 to cut the antenna body 8, so that the antenna is automatically fixed during the wire cutting process, the time for fixing the antenna body 8 during wire cutting is reduced, and the wire cutting efficiency is improved.

[0026] Among them, in order to achieve the purpose of pressing the antenna body 8 when cutting the wire, the present device adopts the following technical solutions: the wire cutting and pressing unit includes a connecting rod 14, the top and bottom of the connecting rod 14 are respectively fixed with an anti-slip baffle 15 and a pressing plate 17, the outside of the connecting rod 14 is sleeved with a spring 16, and the bottom of the pressing plate 17 is fixed with an anti-slip pad 18, the connecting rod 14 passes through the connecting plate 13 and is slidably connected to the connecting plate 13, the top of the spring 16 is fixedly connected to the connecting plate 13, and the bottom of the spring 16 is fixedly connected to the pressing plate 17, when the connecting plate 13 moves downward, the connecting rod 14, the anti-slip baffle 15, the spring 16, the pressing plate 17, and the anti-slip pad 18 move synchronously, when the anti-slip pad 18 contacts the antenna body 8, the pressing plate 17 stops moving, and the antenna body 8 is pre-fixed, at this time the connecting plate 13 continues to move downward, so that the spring 16 contracts, the pressure on the antenna body 8 increases, and the antenna body 8 is gradually compressed;

[0027] In order to achieve the purpose of supporting the antenna body 8 and preventing the antenna body 8 from deflecting, the device adopts the following technical solution: the rotating wheel 7 is arranged inside the bracket 6 and connected to the bracket 6 through a bearing, the antenna body 8 is arranged on the top of the two rotating wheels 7 and is slidably connected to the two rotating wheels 7, and the antenna body 8 is placed on the top of the two rotating wheels 7 when cutting the wire, so that the antenna body 8 is at the top of the trapezoidal block 4, so that the antenna body 8 can only move on the top of the rotating wheel 7 when moving, so that the antenna body 8 is below the cutter 12, preventing the antenna body 8 and the cutter 12 from being misaligned;

[0028] Among them, in order to prevent the antenna body 8 from being incompletely cut, the present device adopts the following technical solution: the push rod 10 passes through the top of the top plate 3 and is slidably connected to the top of the top plate 3, the width of the groove 5 is greater than the thickness of the cutter 12, and the groove 5 allows the cutter 12 to be lower than the surface of the connecting rod 14, so that the cutter 12 can completely cut the antenna body 8.

[0029] The use process of the utility model is as follows: when using the utility model, the hydraulic cylinder 9 is connected with the hydraulic device to provide power for the support 6 to work. When cutting the wire, the antenna body 8 is placed on the top of the two rotating wheels 7, so that the antenna body 8 is at the top of the trapezoidal block 4 and contacts the trapezoidal block 4. When the hydraulic cylinder 9 is started, the hydraulic cylinder 9 makes the push rod 10 move downward, and the push rod 10 moves through the cutter mounting seat 11 to make the cutter 12 move downward. At the same time, when the push rod 10 moves, the connecting rod 14, the anti-slip baffle 15, the spring 16, the pressure plate 17, and the anti-skid pad 18 move synchronously through the connecting plate 13. When the anti-skid pad 18 is moved, the connecting rod 14, the anti-slip baffle 15, the spring 16, the pressure plate 17, and the anti-skid pad 18 move synchronously. When the pad 18 contacts the antenna body 8, the pressure plate 17 stops moving and the antenna body 8 is pre-fixed. At this time, the connecting plate 13 continues to move downward, so that the spring 16 contracts, the pressure on the antenna body 8 increases, and the antenna body 8 is gradually compressed. Then the cutter 12 contacts the antenna body 8 to cut the antenna body 8. The groove 5 allows the cutter 12 to be lower than the surface of the connecting rod 14, so that the cutter 12 can completely cut the antenna body 8, so as to automatically fix the antenna during the wire cutting process, reduce the time for fixing the antenna body 8 during wire cutting, and improve the wire cutting efficiency.
