AI Technical Summary
In the existing resonant rod processing device, negative pressure adsorption is easily formed at the connection between the punch and the resonant rod during the stretching process, making it difficult to pull the resonant rod out of the punch. In addition, the punch does not limit the bottom of the resonant rod, which can easily cause bottom deformation and affect the quality of the finished product.
A resonant rod processing and stretching device was designed. The pressure plate and the shaping plate contact the upper and lower ends of the resonant rod respectively. The shaping plate limits the bottom of the resonant rod. After stamping, the shaping plate and the connecting plate are separated by nuts and threads to avoid negative pressure adsorption. At the same time, lubricating oil is used to reduce friction.
This improved the ease of material handling, prevented deformation of the bottom of the resonant rod, ensured processing results, and enhanced the ease of use and processing quality of the device.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of resonant rod processing technology, specifically relating to a resonant rod processing and stretching device. Background Technology
[0002] A resonant rod is an essential component used in aerospace, broadcasting, and communication base station equipment. Also known as a vibrator, reflector rod, resonant oscillator, or resonant column, a patent document with authorization announcement number CN 219357559 U discloses a stretching mold for a resonant rod. The mold includes a base plate, with two columns fixedly mounted on the top of the base plate. A lower mold is fixedly mounted on the top of the two columns. Hydraulic push rods are fixedly mounted on the top of the base plate and on both sides of the columns. A horizontal plate is fixedly mounted on the output end of the two hydraulic push rods, and an upper mold is fixedly mounted on the bottom of the horizontal plate. In this stretching mold, lubricating oil is added to the oil tank via an oil filler. When the hydraulic push rods are operated using a controller for stretching operations, the controller delays opening the filling valve, allowing the lubricating oil in the oil tank to enter the cavity through the filling pipe and seep into the workpiece through the oil seepage hole. This lubricates the workpiece and mold surfaces, effectively preventing scratches on the product surface and "adhesion nodules" on the mold surface.
[0003] Although the above-mentioned device reduces the friction between the mold and the workpiece by adding lubricant during use, the lubricant present in the cavity between the punch and the resonant rod during the stretching process can easily create a negative pressure at the connection between the punch and the resonant rod, causing the resonant rod to be attracted to the punch. When the punch moves up later, it can easily move the resonant rod along with it, making it difficult to pull the resonant rod out of the punch. Furthermore, the punch does not limit the bottom of the resonant rod during the stamping process. When the punch applies pressure downward from inside the resonant rod, it can easily cause the bottom of the resonant rod to deform and form an arc surface, thus affecting the quality of the finished resonant rod. Utility Model Content
[0004] The purpose of this invention is to provide a resonant rod processing and stretching device, which can assist workers in removing the processed resonant rod, improve the convenience of the device, and also shape and limit the bottom of the resonant rod to avoid deformation of the bottom of the resonant rod affecting the processing effect.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A resonant rod processing and stretching device includes a base, the upper surface of which is fixedly connected to the bottom end of a placement frame and a fixing frame. The upper end of the placement frame is provided with a placement hole, and the resonant rod body is sleeved in the placement hole.
[0007] The bottom of the upper end of the resonant rod body overlaps with the upper surface of the placement frame, the top of the upper end of the resonant rod body overlaps with the bottom surfaces of the two pressure plates, and the bottom surface of the resonant rod body overlaps with the upper surface of the shaping plate.
[0008] The opposite ends of the two pressure plates are rotatably connected to the upper optical shafts of the two screws via rolling bearings, and the two screws are threadedly connected to the two threaded holes respectively.
[0009] The two threaded holes are respectively opened at the bottom ends of the two fixing plates, and the top ends of the two fixing plates are fixedly connected to the upper end of the placement frame.
[0010] The shaping plate is simultaneously sleeved with two through slots, which are respectively opened on the left and right sides of the placement frame. The left and right ends of the shaping plate are respectively fixedly connected to the bottom ends of two connecting rods.
[0011] The upper ends of the two connecting rods are respectively fitted into two sleeve holes, both of which are opened in the connecting plate. The upper end of each connecting rod is provided with a threaded groove and threadedly connected to a nut.
[0012] The left and right ends of the connecting plate are fixedly connected to the upper ends of the two electric push rods, and the bottom ends of the two electric push rods are fixedly connected to the base.
[0013] An oil storage tank is fixedly installed at the upper end of the fixed frame. The bottom surface of the oil storage tank is fixedly connected to the upper end of the connecting hose. A valve is installed on the upper side of the connecting hose.
[0014] The bottom end of the connecting hose is fixedly connected to the upper end of the punch and communicates with the oil storage chamber, which is located inside the punch. The upper end of the punch is fixedly connected to the middle of the connecting plate.
[0015] The punch has multiple oil seepage holes on its outer side that communicate with the oil storage cavity, and the punch is sleeved inside the resonant rod body.
[0016] The technical effects achieved by this utility model are as follows:
[0017] This invention uses a pressure plate and a shaping plate that contact the upper and lower ends of the resonant rod body, respectively. During the punching and stretching process of the resonant rod body, the shaping plate can be used to limit and shape the bottom of the resonant rod body by contacting the bottom of the resonant rod body. This avoids the formation of an arc surface at the bottom of the resonant rod body during the punching and stretching process, which would affect the processing effect. After processing, when the punch moves up and detaches from the resonant rod body, the nut is removed from the connecting rod, allowing the shaping plate to separate from the connecting plate. At this time, the pressure plate is used to press and fix the resonant rod body, thus avoiding the formation of negative pressure adsorption between the punch and the resonant rod body, which would make separation difficult. This improves the convenience of material handling in this device. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figure 1-4 As shown, a resonant rod processing and stretching device includes a base 1. The upper surface of the base 1 is fixedly connected to the bottom end of both the placement frame 2 and the fixing frame 7. The upper end of the placement frame 2 is provided with a placement hole 16, and the resonant rod body 4 is sleeved inside the placement hole 16.
[0026] The bottom of the upper end of the resonant rod body 4 overlaps with the upper surface of the placement frame 2, the top of the upper end of the resonant rod body 4 overlaps with the bottom surfaces of the two pressure plates 18, and the bottom surface of the resonant rod body 4 overlaps with the upper surface of the shaping plate 3.
[0027] Furthermore, the opposite ends of the two pressure plates 18 are rotatably connected to the upper optical shafts of the two screws 14 via rolling bearings. The two screws 14 are threadedly connected to the two threaded holes 15. When using this device to punch and stretch the resonant rod body 4, the user can place the raw material on the upper end of the placement rack 2 and make the stretching part correspond to the placement hole 16. At this time, the user can rotate the screw 14 to make the screw 14 descend along the threaded hole 15 and restrict the position of the pressure plate 18 so that the pressure plate 18 corresponds to the resonant rod body 4. When the pressure plate 18 presses the resonant rod body 4 tightly, the screw 14 is stopped from rotating, thereby avoiding the formation of negative pressure adsorption between the punch 21 and the resonant rod body 4, which makes separation difficult, thus improving the convenience of material handling of this device.
[0028] Furthermore, two threaded holes 15 are respectively opened at the bottom ends of the two fixing plates 17, and the top ends of the two fixing plates 17 are fixedly connected to the upper end of the placement frame 2.
[0029] Furthermore, the shaping plate 3 is simultaneously sleeved with two through slots 12, which are respectively opened on the left and right sides of the placement frame 2. The left and right ends of the shaping plate 3 are respectively fixedly connected to the bottom ends of two connecting rods 5.
[0030] Furthermore, the upper ends of the two connecting rods 5 are respectively fitted into the two sleeve holes 22, both of which are opened in the connecting plate 8. The upper end of each connecting rod 5 is provided with a threaded groove and threadedly connected to the nut 19. After the resonant rod body 4 is fixed by the pressure plate 18, the electric push rod 6 is controlled to retract, causing the connecting plate 8 and the punch 21 to descend. When the bottom end of the punch 21 contacts the inside of the resonant rod body 4, the retraction of the electric push rod 6 is stopped. Then, the shaping plate 3 contacts the bottom of the resonant rod body 4, and the connecting rod 5 is passed through the sleeve hole 22. Then, the nut 19 is threadedly connected to the threaded groove at the upper end of the connecting rod 5, and the nut 19 is rotated to make the shaping plate 3 and the bottom of the resonant rod body 4 in tight contact, limiting and shaping the bottom of the resonant rod body 4, thereby avoiding the formation of an arc surface at the bottom of the resonant rod body 4 during the punching and stretching process of the punch 21, which would affect the processing effect.
[0031] Furthermore, the left and right ends of the connecting plate 8 are fixedly connected to the upper ends of the two electric push rods 6 respectively, and the bottom ends of the two electric push rods 6 are fixedly connected to the base 1.
[0032] Furthermore, an oil storage tank 11 is fixedly installed at the upper end of the fixed frame 7. The bottom surface of the oil storage tank 11 is fixedly connected to the upper end of the connecting hose 9. A valve 10 is installed on the upper side of the connecting hose 9. During the processing, the valve 10 is opened so that the lubricating oil in the oil storage tank 11 flows into the oil storage chamber 13 through the connecting hose 9. The lubricating oil in the oil storage chamber 13 flows into the interior of the resonant rod body 4 through the oil seepage hole 20, thereby reducing the friction between the punch 21 and the resonant rod body 4, avoiding scratches inside the workpiece and improving the processing effect.
[0033] Furthermore, the bottom end of the connecting hose 9 is fixedly connected to the upper end of the punch 21 and communicates with the oil storage chamber 13, which is located inside the punch 21. The upper end of the punch 21 is fixedly connected to the middle of the connecting plate 8.
[0034] Furthermore, the outer side of the punch 21 is provided with multiple oil seepage holes 20 that communicate with the oil storage cavity 13, and the punch 21 is sleeved inside the resonant rod body 4.
[0035] The working principle of this utility model is as follows: When using this device to press and stretch the resonant rod body 4, the user can place the raw material on the upper end of the placement rack 2 and make the stretching part correspond to the placement hole 16. At this time, the user can rotate the screw 14 to make the screw 14 descend along the threaded hole 15 and restrict the position of the pressure plate 18 so that the pressure plate 18 corresponds to the resonant rod body 4. When the pressure plate 18 presses the resonant rod body 4 tightly, stop rotating the screw 14. Then the user controls the electric push rod 6 to retract so that the connecting plate 8 and the punch 21 descend. When the bottom end of the punch 21 contacts the inside of the resonant rod body 4, stop the electric push rod 6 to retract. Then the shaping plate 3 contacts the bottom of the resonant rod body 4 and the connecting rod 5 passes through the sleeve hole 22. Then the nut 19 is threadedly connected to the upper threaded groove of the connecting rod 5, and the nut 19 is rotated so that the shaping plate 3 is in close contact with the bottom of the resonant rod body 4.
[0036] Then, control the electric push rod 6 to retract, causing the punch 21 to descend and punch and stretch the resonant rod body 4. At the same time, open the valve 10 to allow the lubricating oil in the oil tank 11 to flow into the oil storage chamber 13 through the connecting hose 9. The lubricating oil in the oil storage chamber 13 flows into the interior of the resonant rod body 4 through the oil seepage hole 20. After the punching is completed, stop the electric push rod 6 from retracting and rotate the nut 19 in the opposite direction to remove the nut 19 from the upper end of the connecting rod 5, so that the shaping plate 3 is separated from the connecting plate 8. Then, control the electric push rod 6 to extend and drive the punch 21 to move upward and separate from the resonant rod body 4. Then, rotate the screw 14 in the opposite direction to make the pressure plate 18 separate from the resonant rod body 4, and rotate the pressure plate 18 to make the pressure plate 18 deviate from the resonant rod body 4. The resonant rod body 4 can then be taken out from the placement hole 16.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
