Description

Technical Field

[0001] This utility model relates to the field of curtain wall edge strip processing technology, specifically a sheet metal punching device for curtain wall edge strip processing. Background Technology

[0002] As an important component of building curtain wall systems, the processing precision of curtain wall edge strips directly affects the installation quality and overall aesthetics of the curtain wall. In the processing of curtain wall edge strips, punching is a key process, used for subsequent connection or functional realization.

[0003] Referring to the patent document: Patent Publication No. CN110978091A, Patent Publication Date 2020-04-10, a sheet metal punching industrial processing device is provided, belonging to the technical field of sheet metal processing equipment. It includes a support frame, a drainage structure, and a limiting structure. By setting up the punching structure, a moving motor drives gears, and with the cooperation of a rack and pinion, a sliding buckle slides along a sliding guide rail, enabling the cutting blade to move and cut, ensuring the completeness of the cut, avoiding secondary punching, ensuring a uniform cut surface, and achieving better cutting results. Simultaneously, with the cooperation of a cylinder, it can cut sheets of different thicknesses to different depths. By setting up the limiting structure, the sheet metal is placed between two "L"-shaped support plates, and is squeezed and positioned by lead screws on both sides. Then, with the rotation of the positioning bolts, the sheet metal is positioned vertically, enabling multi-directional clamping and positioning of the sheet metal, while preventing the sheet metal from splintering or shifting, ensuring the sheet metal remains stable during the punching process and guaranteeing accurate cutting.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: Currently, when punching curtain wall edge strip panels, the panels are usually conveyed by grippers or conveyor belts, passing intermittently through the lower part of the punching equipment for punching. However, because traditional punching equipment does not have limiting devices on both sides of the panel during punching, the panels on both sides are prone to vibration under impact, resulting in burrs and local deformation at the edges of the panel during punching, requiring subsequent secondary processing.

[0005] Therefore, this utility model provides a sheet metal punching device for processing curtain wall edge strips. Utility Model Content

[0006] In order to solve the problems in the existing curtain wall edge strip punching process, such as the lack of effective instantaneous limiting devices on both sides of the punching equipment, which causes the sheet metal to vibrate under impact, resulting in burrs and deformation at the punched edges; the purpose of this utility model is to provide a sheet metal punching device for curtain wall edge strip processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal punching device for processing curtain wall edge strips, comprising a base, characterized in that: a punching device is fixedly installed at the center of the top of the base, and two sets of symmetrically distributed limiting mechanisms are provided at the top of the base for limiting the punched curtain wall edge strip sheet metal, the limiting mechanisms comprising: The control assembly includes two adjusting frames fixedly mounted on the top of the base. Rotating shafts are rotatably mounted on both sides of each adjusting frame. A drive assembly is located at the top of one of the rotating shafts. Transmission bevel gears are fixedly mounted on the lower parts of multiple rotating shafts. Support rollers are rotatably mounted on the lower parts of both adjusting frames. Support bevel gears are fixedly mounted on both ends of the two support rollers. Multiple transmission bevel gears mesh with the support bevel gears. Lifting plates are located on the upper parts of both adjusting frames. Limiting rollers are rotatably mounted on the lower parts of both lifting plates. Limiting bevel gears are fixedly mounted on both ends of the two limiting rollers. Active bevel gears are rotatably mounted on the lower parts of both sides of the two lifting plates. A rotating shaft slides through the middle of the active bevel gear, and the active bevel gear meshes with the limiting bevel gear. An adjustment component, located on the upper part of the lifting plate, is used to adjust the height of the limit roller.

[0008] Preferably, the adjustment assembly includes multiple limiting springs fixedly installed on the top of the lifting plate, and the tops of the multiple limiting springs are all fixedly installed on the lower middle surface of the adjustment frame.

[0009] Preferably, the drive assembly includes a drive motor fixedly mounted on one side of the top of the adjustment frame, wherein the top of one of the rotating shafts is fixedly mounted on the drive end of the drive motor, and the two rotating shafts are connected by a synchronous belt drive.

[0010] Preferably, two symmetrically distributed drive blocks are fixedly installed on the outer surface of each of the plurality of rotating shafts, and the plurality of drive blocks are slidably engaged in the middle of the active bevel gear.

[0011] Preferably, each of the two adjustment frames has two symmetrically distributed moving slots in the middle, and the two lifting plates are slidably locked in the middle of the moving slots on both sides.

[0012] Preferably, multiple telescopic rods are fixedly installed at equal intervals in the middle of both adjustment frames, the drive ends of the multiple telescopic rods are fixedly installed in the middle of the top of the lifting plate, and multiple limit springs are sleeved on the outside of the telescopic rods.

[0013] Beneficial effects This utility model provides a sheet metal punching device for processing curtain wall edge strips. Compared with the prior art, it has the following advantages: 1. This application drives the rotating shaft to rotate via a drive motor, which in turn drives the transmission bevel gear and the active bevel gear to rotate, thereby driving the support roller and the limit roller to rotate relative to each other. This allows the sheet metal to be stably and automatically transported to the designated station during the stamping interval. At the same time, even if the drive stops during the instant the stamping equipment is in operation, the upper and lower rollers can still effectively suppress the vibration and displacement of the sheet metal caused by the stamping impact by their clamping action, ensuring the continuity of the punching process. On the other hand, it significantly improves the punching positioning accuracy and reduces the generation of burrs and deformation in the punched parts.

[0014] 2. This application uses a limiting spring that is pressed when the sheet material is fed in, causing the lifting plate and limiting roller to move upward, thereby automatically adjusting the clamping gap to match the sheet material thickness. This ensures that the limiting roller can always apply a uniform and vertical clamping force to the sheet material, which not only avoids overpressure damage to the sheet material surface, but also maintains a stable limit during the stamping process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a sheet metal punching device for processing curtain wall edge strips, including a base 1. The upper part of the base 1 has multiple guide grooves for convenient fixing and installing a punching device 11. The punching device 11 is fixedly installed at the top center of the base 1. The curtain wall edge strip sheet to be punched is conveyed by an existing conveyor belt or intermittently moving grippers, arranged on both sides of the punching device 11 for conveying and unloading, respectively. The top of the base 1 has two sets of symmetrically distributed limiting mechanisms 2 for limiting the punched curtain wall edge strip sheet. The limiting mechanism 2 includes: The control assembly 21 includes two adjusting frames 219 fixedly mounted on the top of the base 1. A rotating shaft 213 is rotatably mounted on both sides of each adjusting frame 219. A drive assembly is located at the top of one of the rotating shafts 213. A transmission bevel gear 212 is fixedly mounted on the lower part of each of the multiple rotating shafts 213. A support roller 211 is rotatably mounted on the lower part of each of the two adjusting frames 219. Support bevel gears 2111 are fixedly mounted on both ends of each of the two support rollers 211. The multiple transmission bevel gears 212 mesh with the support bevel gears 2111. When the rotating shaft 213 rotates, it drives the lower transmission bevel gears 212 to rotate, causing the meshing support bevel gears 2111 to rotate, thereby enabling the lower support rollers 211 to rotate. A lifting plate 214 is located on the upper part of each of the two adjusting frames 219. A limit roller 215 is rotatably mounted on the lower part of each of the two lifting plates 214. The limit rollers 215 and the outer surfaces of the support rollers 211 are fitted with... Equipped with a wear-resistant rubber layer, it ensures smooth conveying of the sheet material and avoids scratching the surface of the sheet material. Both ends of the two limiting rollers 215 are fixedly installed with limiting bevel gears 216, and the lower sides of the two lifting plates 214 are rotatably installed with driving bevel gears 217. The rotating shaft 213 slides through the middle of the driving bevel gear 217. The driving bevel gear 217 and the limiting bevel gear 216 are meshed and connected to each other. The driving bevel gear 217 rotates synchronously under the rotation of the rotating shaft 213. Since the driving bevel gear 217 and the transmission bevel gear 212 are symmetrically arranged, the rotation of the driving bevel gear 217 and the meshing transmission with the limiting bevel gear 216 can make the limiting rollers 215 and the support rollers 211 rotate relative to each other. This can limit the conveying of the sheet material passing through the middle, and avoid the problem of burrs on the stamped parts caused by the impact force generated during the stamping process, which would cause the ends of the sheet material on both sides of the stamping equipment 11 to shake. Adjustment component 22 is located on the upper part of lifting plate 214 and is used to adjust the height of limit roller 215.

[0023] The adjustment assembly 22 includes multiple limit springs 221 fixedly installed on the top of the lifting plate 214. The tops of the multiple limit springs 221 are all fixedly installed on the lower middle surface of the adjustment frame 219. By setting the limit springs 221, the height of the limit roller 215 can be adaptively adjusted according to the thickness of the plate, thereby adapting to the limit conveying of plates of different thicknesses.

[0024] The drive assembly includes a drive motor 218 fixedly mounted on one side of the top of the adjustment frame 219. The top of one of the rotating shafts 213 is fixedly mounted on the drive end of the drive motor 218. The two rotating shafts 213 are connected by a synchronous belt drive. The drive motor 218 can be a Delta servo motor ECMA series model ECMA-C20807RS. By rotating the drive motor 218, one of the rotating shafts 213 can be rotated. By driving the synchronous belt, the two rotating shafts 213 located on the same side can be rotated synchronously and intermittently.

[0025] Two symmetrically distributed drive blocks 2131 are fixedly installed on the outer surface of multiple rotating shafts 213. The drive blocks 2131 are slidably locked in the middle of the active bevel gear 217. By locking the drive blocks 2131 in the middle of the active bevel gear 217, it is ensured that the active bevel gear 217 can rotate synchronously with the rotating shaft 213 and slide along the axial direction of the rotating shaft 213.

[0026] Two symmetrically distributed moving slots 2141 are provided in the middle of each of the two adjusting frames 219. The two sides of the two lifting plates 214 are slidably locked in the middle of the moving slots 2141. The moving slots 2141 can guide the lifting and lowering movement of the lifting plates 214, thereby ensuring the stability of the lifting process of the lifting plates 214.

[0027] Multiple telescopic rods 222 are fixedly installed at equal intervals in the middle of the two adjusting frames 219. The driving ends of the multiple telescopic rods 222 are fixedly installed at the top center of the lifting plate 214. Multiple limiting springs 221 are sleeved on the outside of the telescopic rods 222. The telescopic rods 222 limit the extension and retraction direction of the limiting springs 221, preventing the limiting springs 221 from shifting laterally. This ensures the stability of the limiting rollers 215 in limiting the plate material when they move up and down.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the curtain wall edge strip material to be punched enters from one side of the punching equipment 11 and enters the clamping area formed by the support roller 211 and the limiting roller 215 on the same adjusting frame 219. The insertion of the material will push up the limiting roller 215. The limiting roller 215 compresses the upper limiting spring 221 through the lifting plate 214. Under the continuous pressure provided by the limiting spring 221, the limiting roller 215 and the lower support roller 211 work together to press the material tightly in the middle, so as to avoid the curtain wall edge strip material from shaking up and down on both sides during the punching process, which would easily cause burrs to be generated during punching. When step-feeding of the sheet material is required, the drive motor 218 starts, driving the connected rotating shaft 213 to rotate. This rotating shaft 213 drives another rotating shaft 213 on the same side to rotate synchronously via a synchronous belt. This causes the transmission bevel gear 212 at its lower part to rotate, driving the support bevel gear 2111 that meshes with it to rotate, thereby driving the lower support roller 211 to rotate. At the same time, the drive block 2131 on the rotating shaft 213 drives the active bevel gear 217 to rotate synchronously. The active bevel gear 217 then drives the limiting bevel gear 216 that meshes with it, ultimately causing the limiting roller 215 to rotate in the opposite direction to the support roller 211. Under the relative rotation of the upper and lower rollers, The sheet metal clamped in the middle is precisely and smoothly conveyed to one side. After the conveying is completed, the drive motor 218 stops, and the device enters the stamping preparation state. At the moment when the stamping equipment 11 performs the punching operation, a huge impact force and vibration will be generated. At this time, although the drive motor 218 stops and the sheet metal is no longer actively conveyed, the limit roller 215 and support roller 211 pressed by the limit spring 221 still firmly clamp the sheet metal located on both sides of the stamping point from the upper and lower sides. This effectively suppresses the vibration or displacement of the sheet metal caused by the stamping impact, ensures the positioning accuracy of the sheet metal at the moment of stamping, and reduces the risk of defects such as burrs and deformation in the punched parts.
