Description

Technical Field

[0002] With the development of industrial technology, the modern communication industry has become more and more perfect. Communication equipment requires a lot of beading during production and installation. Beading is a material cut from sheet metal. In the past, metal beading needed to be impacted multiple times during stamping, and each impact required positioning. This operation was more troublesome, wasted manpower and material resources, and increased processing costs.

[0003] For example, a punching device for microwave antenna beading disclosed in Patent No. 201911205507.X includes a supporting lower plate, a supporting upper plate arranged parallel and spaced above the supporting lower plate, and a plurality of punching mechanisms spaced apart on the supporting upper plate; the gap between the supporting lower plate and the supporting upper plate forms a positioning area for the beading to be placed and positioned; any punching mechanism includes a hydraulic cylinder fixed to the supporting upper plate and a punch fixed to the piston rod of the hydraulic cylinder, and a through hole for the punch to extend into the positioning area is opened at a position corresponding to any punching mechanism on the supporting upper plate;

[0004] The device also has the following defects when in use. First, the device needs to process multiple steps when processing sheet metal strips. Each processing step requires moving a workstation, which also requires back and forth positioning. This processing operation increases the processing cost. Second, there will be tiny flanges on the edges of the sheet metal material that are impacted. These tiny flanges affect the outline of the sheet metal material, which causes interference between the sheet metal blocks during installation. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and provide a punching device and punching process for microwave antenna strips. When the device is in use, the winding roller and the feeding roller to be processed are respectively placed on the extended shaft seat.

Then the hydraulic press drives the pressure platform to move downward to start the impact operation. When the pressure platform passes through the inner ring of the mold ring, the pressure platform and the delay ring are staggered by a small distance. After the reset spring is fully compressed, the delay ring impacts the sheet metal again, allowing the sheet metal to press out a ring-shaped material, thereby realizing automatic impact of the ring material.

A winding roller is rotatably installed between a group of extension shaft seats at the left end, and a feeding roller is rotatably installed between the extension shaft seats at the right end. The sheet metal is pulled out from the feeding roller and connected to the winding roller.

[0014] Furthermore, the grinding and chamfering mechanism includes a docking shaft seat, a filling notch matching the docking shaft seat is provided on the grinding table, an arch bridge is rotatably installed on one side of the docking shaft seat, and a grinding motor is provided at the end of the arch bridge, a grinding block is installed at the output end of the grinding motor, a grinding annular groove is provided on the outside of the grinding block, and the bottom end of the arch bridge is installed on the output end of the lifting motor.

[0015] Further, as follows,

[0016] S1. Place the winding roller and feeding roller to be processed on the extended shaft seat respectively. When the feeding motor drives the winding roller to rotate, the sheet metal material is pushed forward step by step. Then, the hydraulic press drives the pressure platform to move downward to start the impact operation. When the pressure platform passes through the inner ring of the mold ring, the pressure platform and the delay ring are staggered a short distance from each other. After the return spring is fully compressed, the delay ring impacts the sheet metal again, forcing the sheet metal into a ring-shaped material, realizing automatic impact of the ring material. If punching is required in the replacement material, install the impact head at the bottom of the delay ring according to the location of the hole, and then replace the mold ring with the docking hole.

[0017] S2. When the mold ring is once again pushed up by the strong spring, the carrier motor drives the rack to move via the positioning gear. The conveyor plate slides back and forth along the inside of the clamping frame with the rack. When the electromagnet reaches above the ring material, the lifting cylinder contracts and drives the clamping frame downward a short distance, allowing the electromagnet to fit over the ring material and attract it. The zigzag rod extracts the ring material and pushes it onto the grinding table for the next step of processing. This achieves the function of automatically changing the workstation, eliminating the need to manually move the metal ring.

At this time, the grinding motor drives the grinding block to rotate and grind the edges and corners of the metal ring. The positioning motor drives the driven turntable to rotate through the driving turntable and the acceleration belt. The positioning turntable rotates with the driven turntable. After the positioning turntable and the metal ring rotate one circle, the burrs and fins of the metal ring are polished away, achieving the purpose of polishing the flanging of sheet metal cutting.

[0019] Beneficial effects of the present invention:

[0020] First, when the device is in use, the winding roller and feeding roller to be processed are placed on the extended shaft seat respectively. When the feeding motor drives the winding roller to rotate, the sheet metal material is pushed forward step by step, and then the hydraulic press drives the pressure platform to move downward to start the impact operation. When the pressure platform passes through the inner ring of the mold ring, the pressure platform and the delay ring are staggered from each other by a small distance. After the reset spring is fully compressed, the delay ring impacts the sheet metal again, allowing the sheet metal to press out a ring-shaped material, realizing automatic impact of the ring material. If it is necessary to punch a hole in the replacement material, install the impact head at the bottom end of the delay ring according to the position of the hole, and then replace the mold ring with a docking hole.

[0021] Secondly, when the mold ring is bounced up again by the strong spring, the carrying motor drives the rack to move through the positioning gear, and the conveying plate slides back and forth on the inside of the clamping frame with the rack. When the electromagnet reaches the top of the ring material, the lifting cylinder contracts and drives the clamping frame to move down a short distance so that the electromagnet fits on the ring material and absorbs the ring material. After the bending rod extracts the ring material, it pushes the material to the grinding table for the next processing, realizing the function of automatic station change, and there is no need to manually move the metal ring.

[0022] Third, after the ring-shaped material is placed on the positioning turntable, the lifting motor drives the arch bridge to twist and stand upright. At this time, the grinding motor drives the grinding block to rotate and grind the edges and corners of the metal ring. The positioning motor drives the driven turntable to rotate through the driving turntable and the acceleration belt. The positioning turntable rotates with the driven turntable. After the positioning turntable and the metal ring rotate one circle, the burrs and fins of the metal ring are polished away, achieving the purpose of polishing the flanging of sheet metal cutting.

7. The punching process of the punching device for microwave antenna strip according to claim 6, characterized in that: As follows: S1. Place the winding roller (202) and feeding roller (204) to be processed on the extension shaft seat (201) respectively, and the feeding motor (203) drives the winding roller (202) to rotate to push the sheet metal material forward step by step, and then the hydraulic press (101) drives the pressure platform (102) to move downward to start the impact operation. When the pressure platform (102) passes through the inner ring of the mold ring (701), the pressure platform (102) and the delay ring (103) are staggered by a small distance. After the return spring (104) is fully compressed, the delay ring (103) impacts the sheet metal again, so that the sheet metal is pressed out of a ring-shaped material, realizing automatic impact of the ring material. If it is necessary to punch a hole in the replacement material, an impact head is installed at the bottom end of the delay ring (103) according to the position of the hole, and then the mold ring (701) with a docking hole is replaced; S2. When the mold ring (701) is once again bounced up by the strong spring (702), the carrying motor (503) drives the rack (401) to move through the positioning gear (504), and the conveying plate (4) slides back and forth on the inner side of the clamping frame (5) along with the rack (401). When the electromagnet (403) reaches above the annular material, the lifting cylinder (303) contracts and drives the clamping frame (5) to move down a short distance so that the electromagnet (403) fits on the annular material and absorbs the annular material. After the bending rod (402) extracts the annular material, it pushes the material onto the grinding table (6) for the next processing, realizing the function of automatically changing the workstation, without the need to manually move the metal ring to the workstation; S3. After the ring-shaped material is placed on the positioning turntable (8), the lifting motor (904) drives the arch bridge (901) to twist and stand upright. At this time, the grinding motor (902) drives the grinding block (903) to rotate and grind the edges and corners of the metal ring. The positioning motor (10) drives the driven turntable (1002) to rotate through the driving turntable (1001) and the acceleration belt (1003). The positioning turntable (8) rotates together with the driven turntable (1002). After the positioning turntable (8) and the metal ring rotate one circle, the burrs and flash of the metal ring are completely ground away, achieving the purpose of grinding the flanging of the sheet metal cutting.
