Description

Technical Field

[0001] The utility model relates to the technical field of antenna processing equipment, in particular to an antenna bending device. Background Art

[0002] like Figure 1 As shown, existing V-shaped antennas generally consist of two symmetrically arranged connecting plates, an antenna mounting plate located at the top of the two connecting plates, and a vibrator located on either side of the connecting plates. The antenna mounting plates are wide at the sides and narrow in the middle, with the top of the connecting plates connecting to the middle of the mounting plates. The bottom of the antenna mounting plate can be designed to be V-shaped. In actual production, the connecting plates, antenna mounting plates, and vibrator are all formed from sheet metal. A bending device is then used to bend the two connecting plates, which were originally aligned, to create an inverted V-shape for the antenna.

[0003] Chinese patent publication CN205110456U discloses a downward bending machine that includes an inverted U-shaped bending die. Using this die, combined with a supporting pressure block, the antenna connection plate can be bent into an inverted V shape. However, the antenna can be pulled along by the die during the downward bending process, potentially causing the antenna to fail to meet design requirements.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0036] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0037] See also Figures 3 to 8 The utility model provides an antenna bending device, which can be used to bend an antenna with a vibrator 3 so that the antenna forms an inverted V shape. The device specifically includes a frame 4, a support rod 5, a bending mold 6, a first cylinder 7, a second cylinder 8 and a pressing plate 9.

[0038] The support rod 5 is horizontally arranged on the front side of the frame 4, and the support rod 5 is perpendicular to the length direction of the antenna to be bent (i.e., the antenna that has not been bent yet) in the horizontal direction. During actual operation, the mounting plate of the antenna is supported by the support rod 5. The bending mold 6 is movably arranged above the support rod 5, and a notch 601 is formed upward at its bottom, that is, the bending mold 6 as a whole is in an inverted U shape. When the bending mold 6 moves downward, the bottoms of both sides can contact the connecting plates 2 on both sides of the antenna mounting plate 1, so that the bending mold 6 is squeezed downward, causing the transition area where the connecting plate 2 is connected to the mounting plate to be squeezed and deformed, and the two connecting plates 2 can form an inverted V shape.

[0039] The first cylinder 7 is fixed to the frame 4 and has a telescopic rod that can extend downward. The telescopic rod is connected to the top of the bending die 6, thereby driving the bending die 6 to move up and down. The second cylinder 8 is fixed to the frame 4 and also has a telescopic rod. The telescopic rod of the second cylinder 8 is downwardly connected to the pressing plate 9. The pressing plate 9 is parallel to the horizontal plane. When the bending die 6 moves downward to prepare to bend the antenna connecting plate 2, the telescopic rod of the second cylinder 8 drives the pressing plate 9 to move downward. Before the bottom of the bending die 6 contacts the antenna connecting plate 2, the pressing plate 9 contacts the antenna mounting plate 1 to press the antenna mounting plate 1 tightly. When the bending die 6 continues to move downward to bend the antenna connecting plate 2, it can ensure that the entire antenna will not move, so that the antenna can still meet the design requirements after bending.

[0040] It is understandable that in order for the pressing plate 9 and the bending die 6 to cooperate with each other to complete the bending of the antenna, when the bending die 6 bends the connecting plate 2 of the antenna, the front portion of the pressing plate 9 should be located in the notch 601 .

[0041] like Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, a positioning groove 501 is formed on the upper portion of the support rod 5 for positioning the antenna mounting plate 1. The positioning groove 501 is used to position the V-shaped portion of the antenna mounting plate, so that the antenna to be bent can be quickly placed on the support rod 5, thereby improving antenna processing efficiency.

[0042] like Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the positioning groove 501 is a V-shaped positioning groove 501, whose shape can adapt to the shape of the antenna mounting plate 1. A stopper 10 is provided in the positioning groove 501 and fixed therein. When the antenna mounting plate 1 is placed on the support rod 5, the front end of the V-shaped portion of the antenna mounting plate 1 abuts the stopper 10, thereby limiting the movement of the antenna mounting plate 1 toward the rear of the rack 4.

[0043] When the front end of the V-shaped part of the antenna mounting plate 1 abuts against the limit block 10, the area to be bent on the antenna connecting plate 2 is just below the bottom of both sides of the bending mold 6, so that the antenna can still meet the design requirements after bending.

[0044] like Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, a reinforcing plate 11 is connected to the bottom of the support rod 5, and the other side of the reinforcing plate 11 is connected to the frame 4, thereby increasing the structural strength of the support rod 5, so that the support rod 5 has a high load-bearing capacity, and when the pressure plate 9 acts on the support rod 5, the support rod 5 is not easy to break.

[0045] like Figure 8 As shown, in a preferred embodiment of the present invention, the first cylinder body 7 and the second cylinder body 8 are both air cylinders, and are each connected to a gas branch pipe 12. Furthermore, the two gas branch pipes 12 are commonly connected to a gas main pipe 14, which is connected to a solenoid valve 15. The solenoid valve 15 is electrically connected to a foot switch 16. The foot switch 16 can be connected to the coil assembly of the solenoid valve 15. When the foot switch 16 is stepped on, current flows through the switch to the coil of the solenoid valve 15, activating the solenoid valve 15, thereby allowing the compressed air in the compressed air storage tank to pass through the gas main pipe 14 and then be diverted to the two cylinder bodies via the gas branch pipe 12.

[0046] In this embodiment, the opening of the solenoid valve 15 is controlled by a foot switch 16. Compared with the use of other switches, there is no need for manual operation by the operator. The operator's hands are used to hold and place the antenna. During the production operation, the operator is not easily distracted and the safety hazard is small.

[0047] Of course, the first cylinder body 7 and the second cylinder body 8 may also be hydraulic cylinders.

[0048] like Figure 3 and Figure 6 As shown, in a preferred embodiment of the present invention, the frame 4 includes a workbench 41, a vertical plate 42 vertically mounted on the workbench 41, and a horizontal plate 43 perpendicularly connected to the front of the vertical plate 42. The first cylinder 7 and the second cylinder 8 are detachably mounted on the horizontal plate 43. The vertical plate 42 is provided with a waist-shaped hole 421, which allows the gas branch pipe 12 to pass through. The waist-shaped hole 421 can restrain the gas branch pipe 12. When compressed air flows at high speed in the gas branch pipe 12, the gas branch pipe 12 has a small amplitude of vibration, which does not pose a safety hazard.

[0049] like Figure 8 As shown, in a preferred embodiment of the present invention, the gas branch pipe 12 is connected to a flow control valve 13. The flow control valve 13 can adjust the flow of compressed air in the gas branch pipe 12, thereby controlling the stroke of the telescopic rod of the first cylinder 7 and the telescopic rod of the second cylinder 8, so that the pressing plate 9 can contact and press the antenna mounting plate 1 before the bottom of the bending die 6 contacts the antenna connecting plate 2.

[0050] like Figure 6 and Figure 7As shown, in a preferred embodiment of the present invention, a guide rod 17 is vertically disposed above the pressing plate 9. The guide rod 17 is vertically and movably disposed through the horizontal plate 43. The number of guide rods 17 is not limited to one. The guide rod 17 guides the pressing plate 9, ensuring that the pressing plate 9 remains parallel to the horizontal plane during its vertical movement. When the pressing plate 9 is parallel to the horizontal plane, the pressing plate 9 can firmly press the antenna mounting plate 1.

[0051] like Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, the bottoms of the first cylinder 7 and the second cylinder 8 are connected with support columns 18. There are preferably four support columns 18 at the bottom of each cylinder, and the support columns 18 are located at the four corners of the bottom of the cylinder to ensure that the first cylinder 7 and the second cylinder 8 can be stably supported.

[0052] The support column 18 is inserted through the transverse plate 43 and is sleeved with a nut 19; the nut 19 is located below the transverse plate 43 and is used to securely connect the support column 18 to the transverse plate 43, thereby enabling the installation of the first cylinder body 7 and the second cylinder body 8. When the first cylinder body 7 and the second cylinder body 8 need to be removed from the frame 4, the nut 19 is loosened and the support column 18 is moved upward and out of the transverse plate 43, thereby facilitating the installation and removal of the first cylinder body 7 and the second cylinder body 8.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
