Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, specifically to a processing device for opening and lifting rings of fire extinguishers. Background Technology

[0002] With the continuous improvement of fire safety awareness, fire extinguishers, as essential emergency fire-fighting equipment, have seen a continuous increase in market demand. In the production process of the fire extinguisher's opening ring, steel wire cutting is the core processing step. The cutting quality directly determines the dimensional consistency and assembly compatibility of the ring, thus affecting the safety of the fire extinguisher. Therefore, a high-efficiency fire extinguisher opening ring processing device is needed to cut the raw steel wire for the ring.

[0003] However, existing processing equipment mostly uses a single-state control for guiding and fixing the raw steel wire of the lifting ring during use, which is not convenient for flexible switching between guiding and conveying and locking and fixing. This can cause the steel wire to move around easily when it is cut, making it difficult to provide a reliable positioning basis for cutting. Summary of the Invention

[0004] The purpose of this invention is to provide a processing device for opening and lifting rings of fire extinguishers. By setting up a state switching unit, it solves the problem that existing processing devices mostly control the guidance and fixing of the lifting ring raw material steel wire in a single state during use, which is not convenient to achieve flexible switching between guiding and conveying and locking and fixing. This will cause the steel wire to move around easily when cutting, making it difficult to provide a reliable positioning basis for cutting.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a processing device for the opening and lifting ring of a fire extinguisher, comprising a frame and a rectangular groove formed within the frame, and further comprising: a cutting section disposed on the frame; two state switching sections, which are mirror images of each other mounted on the frame; an adjusting section disposed on the inner wall of the rectangular groove; a fixing section disposed on the frame; the state switching section includes an adjusting assembly disposed on the frame; and an elastic assembly mounted on the frame; the adjusting assembly includes a fixing plate disposed on the frame, with two connecting blocks fixedly connected to the front side of the fixing plate, two spring dampers fixedly connected to the front side of each of the two connecting blocks, and two friction blocks fixedly connected to the front side of each of the two spring dampers, with a friction ring disposed in front of each of the two friction blocks, and the two friction blocks respectively fitting with the two friction rings.

[0006] Furthermore, the elastic component includes two spring dampers II fixedly connected to the front side of the fixed plate, and a U-shaped frame fixedly connected to the front side of the two spring dampers II. A rotating shaft I is rotatably connected to the U-shaped frame, and guide rollers are fixedly connected to the outer walls of the two rotating shafts I. The tops of the two rotating shafts I rotatably extend outside the U-shaped frame, and the outer walls of the two rotating shafts I are respectively fixedly connected to the inner walls of the two friction rings.

[0007] Furthermore, the cutting section includes a bracket fixedly connected to the top of the frame, a hydraulic cylinder fixedly connected to the bracket, the output shaft of the hydraulic cylinder being slidably connected to the bracket, a blade holder fixedly connected to the output shaft of the hydraulic cylinder, and a guide member provided on the blade holder; the bracket is located to the right of the state switching section, the guide member includes two guide rods fixedly connected to the blade holder, and a cutting blade is installed at the bottom of the blade holder; both guide rods slide through the bracket, and the cutting blade is located above the two guide rods.

[0008] Furthermore, the adjustment unit includes a drive assembly disposed on the inner wall of the rectangular groove; and a transmission assembly mounted on the frame. The drive assembly includes two support blocks fixedly connected to the inner wall of the rectangular groove, with a motor fixedly connected to the right side of the right support block, and a worm gear rotatably passing through the two support blocks; the output shaft of the motor is fixedly connected to the worm gear via a coupling.

[0009] Furthermore, the transmission assembly includes two rotating shafts rotatably connected to the inner wall of the rectangular groove. Worm gears are fixedly connected to the outer walls of both rotating shafts, and connecting rods are fixedly connected to the outer walls of both rotating shafts. Each connecting rod has a sliding groove, and a cylindrical slider is provided on the inner wall of each sliding groove. The inner walls of the two sliding grooves slide in contact with the outer walls of the two cylindrical sliders, respectively. A sliding element is provided at the top of each cylindrical slider. Both worm gears mesh with worms. The sliding element includes square sliding plates fixedly connected to the tops of the two cylindrical sliders, with the bottoms of the two square sliding plates slidably connected to the frame. The tops of the two square sliding plates are fixedly connected to the fixing plates of the two state switching parts, respectively, and slidably connected to the U-shaped frames of the two state switching parts.

[0010] Furthermore, the fixing part includes a plurality of spring dampers three fixedly connected to the inner wall of the top of the rectangular groove, and two pressure plates are fixedly connected to the bottom of the plurality of spring dampers three; the two pressure plates are mirror images of each other.

[0011] The present invention has the following beneficial effects: This invention, by setting up a state switching unit, allows the guide roller to rotate freely during the wire conveying stage. This, combined with the spring damper of the elastic component, enables centered guidance and smooth conveying of wires of various diameters. When entering the cutting stage, the spring damper of the adjusting component pushes the friction block against the friction ring, locking the rotating shaft through friction. This switches the guide roller from a rotating state to a locked state, fixing the wire and preventing displacement during cutting. This ensures smooth conveying and provides a reliable positioning basis for cutting. (2) By setting an adjustment part, the motor drives the worm gear to mesh with the worm wheel, and through the transmission cooperation of the rotating shaft, connecting rod, cylindrical slider and square slide plate, the two state switching parts are synchronously approached or separated. The distance between the state switching parts is adjusted by electric synchronous transmission, ensuring the stable guidance of the two rollers for various specifications of steel wire and enhancing the versatility of the device. (3) By setting a fixing part, the spring damper drives two mirror pressure plates to press down, pre-tightening the steel wire before the cutting knife moves, and pre-fixing the steel wire a second time during the cutting stage, forming a double fixation with the locking clamp of the state switching part, effectively preventing the steel wire from moving or shifting, further improving the accuracy of the cutting position, avoiding dimensional deviation caused by steel wire displacement, and ensuring the finished product qualification rate of the fire extinguisher opening ring.

[0012] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-8 As shown, the present invention is a processing device for opening and lifting rings of fire extinguishers, including a frame 111 and a rectangular groove 112 formed within the frame 111, and further including: a cutting part 1, which is disposed on the frame 111; two state switching parts 2, which are mirror images of each other mounted on the frame 111; an adjusting part 3, which is disposed on the inner wall of the rectangular groove 112; and a fixing part 4, which is disposed on the frame 111. The cutting part 1 includes a bracket fixedly connected to the top of the frame 111. 113, a hydraulic cylinder 114 is fixedly connected to the bracket 113, the output shaft of the hydraulic cylinder 114 is slidably connected to the bracket 113, and a knife holder 115 is fixedly connected to the output shaft of the hydraulic cylinder 114. A guide is provided on the knife holder 115. The bracket 113 is located to the right of the state switching part 2. The guide includes two guide rods 116 fixedly connected to the knife holder 115. A cutting knife 117 is installed at the bottom of the knife holder 115. Both guide rods 116 slide through the bracket 113, and the cutting knife 117 is located above the two guide rods 116.

[0018] The state switching unit 2 includes an adjustment component 21, which is mounted on the frame 111; and an elastic component 22, which is also mounted on the frame 111. The adjustment component 21 includes a fixed plate 211 mounted on the frame 111. Two connecting blocks 212 are fixedly connected to the front side of the fixed plate 211. Two spring dampers 213 are fixedly connected to the front side of each connecting block 212. Two friction blocks 214 are fixedly connected to the front side of each spring damper 213. A friction ring 215 is provided in front of each friction block 214. The two friction blocks 214 are respectively adapted to the two friction rings 215. The elastic component 22 includes a fixed plate 211 mounted on the frame 111. Two spring dampers 221 are fixedly connected to the front side of the fixed plate 211. A U-shaped frame 222 is fixedly connected to the front side of the two spring dampers 221. A rotating shaft 223 is rotatably connected to the U-shaped frame 222. Guide rollers 224 are fixedly connected to the outer walls of the two rotating shafts 223. The tops of the two rotating shafts 223 extend rotatably to the outside of the U-shaped frame 222. The outer walls of the two rotating shafts 223 are fixedly connected to the inner walls of the two friction rings 215 respectively. By setting the state switching part 2, the rollers can be switched from the rotating state to the locked state to fix the steel wire and prevent displacement during cutting. This ensures smooth conveying and provides a reliable positioning basis for cutting.

[0019] The adjustment unit 3 includes a drive assembly 31, which is disposed on the inner wall of the rectangular groove 112; and a transmission assembly 32, which is mounted on the frame 111. The drive assembly 31 includes two support blocks 311 fixedly connected to the inner wall of the rectangular groove 112. A motor 312 is fixedly connected to the right side of the support block 311 located on the right side. A worm gear 314 rotatably passes through the two support blocks 311. The output shaft of the motor 312 is fixedly connected to the worm gear 314 via a coupling. The transmission assembly 32 includes two rotating shafts 321 rotatably connected to the inner wall of the rectangular groove 112. A worm wheel 322 is fixedly connected to the outer wall of each of the two rotating shafts 321. A connecting rod 323 is fixedly connected to the outer wall of each of the two rotating shafts 321. A sliding groove 324 is provided on each of the two connecting rods 323. The inner walls of the grooves 324 are each provided with cylindrical sliders 325. The inner walls of the two grooves 324 slide in contact with the outer walls of the two cylindrical sliders 325 respectively. The tops of the two cylindrical sliders 325 are provided with sliding members. The two worm gears 322 are meshed with the worm 314. The sliding members include square slide plates 326 that are fixedly connected to the tops of the two cylindrical sliders 325 respectively. The bottoms of the two square slide plates 326 are slidably connected to the frame 111. The tops of the two square slide plates 326 are fixedly connected to the fixing plates 211 of the two state switching parts 2 respectively. The tops of the two square slide plates 326 are slidably connected to the U-shaped frames 222 of the two state switching parts 2 respectively. By setting the adjustment part 3, the roller spacing can be adjusted to ensure stable guidance of various specifications of steel wire by the two rollers and enhance the versatility of the device.

[0020] The fixing part 4 includes several spring dampers 3 411 fixedly connected to the inner wall of the top of the rectangular groove 112. The bottom of the several spring dampers 3 411 is fixedly connected to two pressure plates 412. The two pressure plates 412 are mirror images of each other. By setting the fixing part 4, a double fixing is formed with the locking clamp of the state switching part 2, which effectively prevents the steel wire from moving or shifting, further improves the accuracy of the cutting position, and ensures the finished product qualification rate of the fire extinguisher opening lifting ring.

[0021] In use, first adjust the distance between the two state switching sections 2 according to the wire specifications, then insert the raw wire. The wire passes between the guide rollers 224 of the two state switching sections 2. Start the motor 312, and its output shaft drives the worm gear 314 to rotate through the coupling. The worm gear 314 meshes with and drives the two worm wheels 322 to rotate synchronously, which in turn drives the two rotating shafts 321 to rotate. The rotating shafts 321 drive the connecting rod 323 to swing. The sliding groove 324 of the connecting rod 323 slides with the cylindrical slider 325, pushing the two square sliding plates 3. 26 are moved away from each other on the frame 111, causing the two state switching parts 2 to separate synchronously; if the gap needs to be reduced, the control motor 312 is reversed, and similarly, the above transmission structure drives the two square slide plates 326 to move closer to each other until they match the diameter of the steel wire. The guide rollers 224 on both sides clamp the steel wire. At this time, the spring damper 221 of the elastic component 22 and the spring damper 213 of the adjustment component 21 are both in a state of no elasticity. The steel wire is centered and guided by the elasticity of the guide rollers 224 and the spring damper 221. After the steel wire is conveyed to the designated position by the external conveying mechanism, the motor 312 is started. The two square slide plates 326 continue to move closer to each other, driving the state switching part 2 to further clamp the steel wire. At this time, the second spring damper 221 and the first spring damper 213 are compressed to generate elastic force. The first spring damper 213 pushes the friction block 214 to abut against the friction ring 215. The friction force prevents the first rotating shaft 223 from rotating, thereby locking the guide roller 224 and fixing the steel wire to prevent displacement during cutting. Finally, the hydraulic cylinder 114 on the top support 113 of the frame 111 is activated, and its output shaft pushes the cutter holder 115 downward. The spring damper 411 drives the two mirror-mounted pressure plates 412 to press down, initially fixing the steel wire on the frame 111. The two guide rods 116 on the cutter holder 115 provide guidance for the cutter holder 115 to ensure that the cutter holder 115 moves smoothly. The cutting blade 117 at the bottom of the cutter holder 115 cuts the fixed steel wire, thereby completing the cutting process of the raw steel wire for a single pull ring.

[0022] It should be noted that the control of the hydraulic cylinder 114 and the motor 312 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.
