Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window fixing plate processing technology, and more specifically, to a shearing device for producing door and window fixing plates. Background Technology
[0002] Door and window fixing plates are metal fittings used to secure doors and windows. They are usually made of thin steel plates and are long strips or L-shaped. The function of door and window fixing plates is to firmly connect doors and windows to the wall, ensuring the stability and safety of the doors and windows. Door and window fixing plates are generally installed around the door and window and fixed to the wall with expansion bolts or self-tapping screws. During the installation of doors and windows, fixing plates can adjust the position of the doors and windows and ensure the verticality and horizontality of the doors and windows.
[0003] A shearing device for producing door and window fasteners is a specialized piece of equipment used to cut metal sheets to produce door and window fasteners. It typically uses a cylinder to drive a cutting blade downwards to cut the door and window fasteners to meet the production requirements of different specifications.
[0004] However, existing shearing devices often have poor support at the cut point when shearing door and window fixing plates. Since door and window fixing plates are made of thin steel plates with high flexibility, the cylinder is prone to deformation or bending at the cut point during the cutting process, which causes many inconveniences in later use. Furthermore, when the cutting blade cuts the fixing plate for a long time, certain impurities often adhere to the outer wall of the cutting blade. The accumulation of these impurities can easily affect the sharpness of the cutting blade, which in turn affects the shearing and causes many inconveniences in practical use.
[0005] Moreover, the existing cutting blade is a very important component in the shearing device, and it is also a consumable item. Personnel often need to replace the cutting blade. However, replacing the existing cutting blade is very inconvenient, requiring personnel to use professional tools to disassemble and install it. The overall replacement process is extremely cumbersome, which undoubtedly affects the replacement efficiency of personnel.
[0006] In view of this, we propose a shearing device for the production of door and window fixing pieces. Utility Model Content

[0013] Preferably, the outer walls at both ends of the descending plate are provided with connecting cylinders, and a reset spring is provided inside the multiple connecting cylinders. The end of the reset spring is provided with a limit post. The bottom of the descending plate is provided with a snap-fit groove that matches the snap-fit plate. The inner wall of the snap-fit groove is provided with a limit groove and a guide groove.
[0014] Preferably, a cutting blade is provided at the bottom of the snap-fit plate, and guide blocks matching the guide groove are provided on the outer walls of both sides of the snap-fit plate.
[0015] Preferably, the snap-fit plate has a cavity inside, and a plurality of the cavities are provided with a second reset spring on the inner wall, and the ends of the plurality of second reset springs are connected to a limiting block that matches the limiting groove.
[0016] Preferably, the two ends of the snap-fit plate are also threaded with threaded rods, and the ends of the multiple threaded rods are connected to limit rods.

[0018] 3. Beneficial effects
[0019] Compared to existing technologies, the advantages of this invention are as follows: When shearing door and window fixing plates, multiple electric push rods can first drive the lower pressure plate downwards. The lower pressure plate then presses and limits the top cutting area of the door and window fixing plate, while the sides of the fixing plate are limited by limiting baffles. This more comprehensively reduces the offset of the door and window fixing plates during the shearing process. Furthermore, the lower pressure plate can better limit the cutting area, thus reducing excessive bending at the cutting edge due to excessive impact when the cylinder drives the cutting blade downwards. Additionally, during the upward movement of the cutting blade, multiple brushes can clean the outer wall of the cutting blade. The dust pump transfers impurities to the collection box, reducing the impact of impurities on the outer wall of the cutting blade and thus its cutting sharpness. When the cutting blade needs to be replaced, multiple limit posts can be pressed first, and the return spring will retract them into the connecting cylinder. Then, the limit rod can be rotated to restore the elliptical protrusion at the end of the threaded rod to a vertical state, thereby releasing the pressure on the limit block. At this time, the multiple limit blocks can be retracted by the return spring, and the snap plate carrying the cutting blade can be easily removed. The installation is carried out by reversing the operation. The overall replacement method is simpler and more convenient, reducing the labor intensity caused by personnel using tools to replace the blade. Attached Figure Description

[0034] Specifically, a drive motor 230 is provided on the side wall of the lower pressure plate 220, and the output ends of multiple drive motors 230 are connected to drive rollers 240 to facilitate the conveying of the fixed plate.
[0035] In some embodiments, a distance sensor may be provided on one side of the outer wall of the pressure plate 220 to facilitate the fixed-length cutting of the fixing plate.
[0036] Furthermore, the lower pressure plate 220 is provided with a dust collection box 250, and the side walls of the multiple dust collection boxes 250 are provided with dust collection ports 260. The multiple dust collection boxes 250 are also provided with brushes 270.
[0037] In some embodiments, the brush 270 is tilted downwards to facilitate cleaning during the upward movement of the cutting blade 332 without affecting its shearing action.
[0038] Furthermore, the outer walls of both ends of the descending plate 320 are provided with connecting cylinders 321, and multiple connecting cylinders 321 are provided with reset springs 322. The end of the reset springs 322 is provided with limit posts 323. The bottom of the descending plate 320 is provided with a snap-fit groove 324 that matches the snap-fit plate 330. The inner wall of the snap-fit groove 324 is provided with a limit groove and a guide groove.
[0039] In some embodiments, the limiting post 323 is used to limit the limiting rod 372 to prevent the threaded rod 370 from shifting or loosening.
[0040] Furthermore, the bottom of the snap-fit plate 330 is provided with a cutting blade 332, and the outer walls on both sides of the snap-fit plate 330 are provided with guide blocks 331 that match the guide groove, so as to facilitate the snap-fit plate 330 to be guided and snapped.
[0041] It is worth noting that the snap-fit plate 330 has a cavity 340 inside, and multiple cavity 340s are provided with reset springs 360 on their inner walls. The ends of multiple reset springs 360 are connected to limit blocks 350 that match the limit grooves.
[0042] It is worth noting that the two ends of the snap-fit plate 330 are also threaded with threaded rods 370. The ends of the multiple threaded rods 370 are connected to limit rods 372. The outer wall of the limit rods 372 is provided with limit holes that match the limit posts 323. The ends of the multiple threaded rods 370 extend into the cavity 340 and are connected to elliptical protrusions 371, which facilitates more convenient limiting and releasing of the snap-fit plate 330.
[0043] In addition, a vacuum pump 410 is installed on the top of the collection box 400. The output end of the vacuum pump 410 is connected to a vacuum hose. The ends of multiple vacuum hoses are connected to the side walls of multiple vacuum boxes 250. A sliding door 420 is connected to the front outer wall of the collection box 400 by a pin.

[0045] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.
[0046] Working principle: When shearing door and window fixing plates, multiple electric push rods 210 first drive the lower pressure plate 220 to descend. The lower pressure plate 220 presses and limits the top cutting point of the door and window fixing plate, while the sides of the door and window fixing plate are limited by the limiting baffles 140. This more comprehensively reduces the deviation of the door and window fixing plate during the shearing process. Moreover, the lower pressure plate 220 can also better limit the cutting point, thereby reducing the excessive bending of the cutting edge caused by excessive impact when the cylinder 310 drives the cutting blade 332 to descend and cut. Secondly, during the rising process of the cutting blade 332, multiple brushes 270 can also clean the outer wall of the cutting blade 332, and the dust pump 410 removes impurities. The blade is transferred to the collection box 400 to reduce the adhesion of impurities on the outer wall of the cutting blade 332, which affects its cutting sharpness. When the cutting blade 332 needs to be replaced, multiple limiting posts 323 can be pressed first, and the return spring 322 will retract into the connecting cylinder 321. Then, the limiting rod 372 can be rotated to make the elliptical protrusion 371 at the end of the threaded rod 370 return to a vertical state, thereby releasing the pressure on the limiting block 350. At this time, the multiple limiting blocks 350 can be driven by the return spring 360 to retract two of the limiting blocks 350. Then, the snap plate 330 carrying the cutting blade 332 can be easily taken out. The installation is carried out by reversing the operation. The overall replacement method is simpler and more convenient, reducing the labor intensity caused by personnel using tools to replace the blade.
