[0020] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Figure 1 This paper shows a schematic diagram of the structure of the fire door sheet metal bending and cutting integrated machine 10 according to one or more embodiments of this application, combined with... Figure 1 The integrated machine 10 provided in this application belongs to the intelligent manufacturing equipment industry. It is used for bending and cutting sheet metal. The integrated machine 10 includes a feeding assembly 100, a cutting assembly 200 and a bending assembly 300 connected in sequence along a first direction. The feeding assembly 100 is used to transport sheet metal to the cutting assembly 200 and the bending assembly 300. The cutting assembly 200 includes a plurality of cutters 211, which can be switched to act on the sheet metal to cut the sheet metal into panels that meet the requirements. The bending assembly 300 includes a support mold 330 and a forming mold 340 that can move relative to each other. The support mold 330 is used to support the panel and the forming mold 340 presses the panel to form a fire door.

[0022] When processing sheet metal using the fire door sheet metal bending and cutting integrated machine 10 provided in this application, the unformed sheet metal is first placed on the feeding assembly 100, which then conveys the sheet metal to the cutting assembly 200 and the bending assembly 300. A suitable cutting tool is selected to cut the sheet metal, forming a panel on the bending assembly 300. The panel, located on the supporting mold 330, is then pressed by the forming mold 340, thus forming the fire door. The fire door sheet metal bending and cutting integrated machine 10 provided in this application can continuously process and form sheet metal, reducing the space occupied during production. The process connections are simple, improving production efficiency, reducing labor costs, and ensuring product quality.

[0023] For ease of description, the length direction of the integrated machine 10 is defined as the first direction, that is, the conveying direction of the sheet metal is defined as the first direction, and the width direction of the integrated machine 10 is defined as the second direction. The specific details of the integrated machine 10 will now be further described with reference to the accompanying drawings.

[0024] Figure 2 It shows Figure 1 A schematic diagram of the feeding assembly 100. (Combined with...) Figure 1 as well as Figure 2In some embodiments, the feeding assembly 100 includes a feeding frame 110 and a plurality of conveying rollers 120. A feeding frame 111 is provided on the top of the feeding frame 110, and the plurality of conveying rollers 120 are rotatably connected to the feeding frame 111. The plurality of conveying rollers 120 are sequentially arranged in the feeding frame 111 along a first direction. Unformed sheet metal is placed in the feeding frame 111 and travels on the plurality of conveying rollers 120, thereby conveying the unformed sheet metal sequentially to the cutting assembly 200 and the bending assembly 300.

[0025] Combination Figure 1 as well as Figure 2 In some embodiments, the feed frame 110 further includes first legs 112, and multiple first legs 112 are respectively disposed on both sides of the bottom of the feed frame 111 in a second direction, so that the feed frame 111 has a certain height, which facilitates the setting of the cutting component 200 and the bending component 300.

[0026] Combination Figure 1 as well as Figure 2 In some embodiments, the feeding assembly 100 further includes a first motor 130, a support base 140, and a feeding roller 150. The first motor 130 and the support roller are disposed opposite each other on both sides of the feeding frame 111 along a second direction. The first motor 130 has a rotatable output section, and the feeding roller 150 has a first end and a second end. The first end of the feeding roller 150 is connected to the output section of the first motor 130, and the second end of the feeding roller 150 is rotatably connected to the support base 140. That is, driven by the first motor 130, the feeding roller 150 can rotate, and the unformed sheet metal is clamped between the feeding roller 150 and the conveying roller 120. The feeding roller 150 drives the unformed sheet metal to move along the first direction on multiple conveying rollers 120. At the same time, the feeding roller 150 can also position the unformed sheet metal, which facilitates the cutting assembly 200 to cut the sheet metal.

[0027] Figure 3 An assembly diagram of the first motor 130 is shown. Figure 4 An assembly diagram of the support base 140 is shown. (Combined with...) Figures 1-4To accommodate the conveying of sheet metal of different thicknesses, in some embodiments, a first seat 160 and a second seat 170 are respectively provided on both sides of the feeding frame 111 along the second direction. The first seat 160 is provided with a first slide groove 161 extending vertically, and the second seat 170 is provided with a second slide groove 171 extending vertically. The first motor 130 is adapted to slide vertically within the first slide groove 161, and the support seat 140 is adapted to slide vertically within the second slide groove 171. The feeding assembly 100 also includes a first elastic element 181 and a second elastic element 182. The first elastic element 181 is vertically disposed between the first seat 160 and the first motor 130. The second elastic element 182 is vertically disposed between the second seat 170 and the support seat 140. In specific implementation, both the first seat 160 and the second seat 170 are U-shaped with the opening 372 facing downwards. The cavities inside are respectively configured as the first slide groove 161 and the second slide groove 171. A first telescopic rod 191 is provided between the top surface of the first motor 130 and the middle part of the first seat 160. A first elastic element 181 is sleeved on the first telescopic rod 191. A second telescopic rod 192 is provided between the top surface of the support seat 140 and the middle part of the second seat 170. A second elastic element 182 is sleeved on the second telescopic rod 192. When the sheet metal is not clamped between the feed roller 150 and the conveying roller 120, the first elastic element 181 and the second elastic element 182 are in a naturally deformed state. The first motor 130 is located at the bottom of the first chute 161, and the support seat 140 is located at the bottom of the second chute 171. When conveying the sheet metal, the sheet metal passes between the feed roller 150 and the conveying roller 120. With the support of the sheet metal, the feed roller 150 is raised, and correspondingly the first motor 130 and the support seat 140 are also raised synchronously. The first telescopic rod 191 and the second telescopic rod 192 are shortened and compressed, and the first elastic element 181 and the second elastic element 182 are compressed. The first elastic element 181 applies a downward force to the motor, and the second elastic element 182 applies a downward force to the support seat 140, thereby causing the feed roller 150 connected between the first motor 130 and the support seat 140 to act on the sheet metal to drive the sheet metal forward.

[0028] It should be noted that in some embodiments, only one conveyor roller 120 may be provided, and this conveyor roller 120 is located at the end of the feed frame 111 away from the cutting assembly 200. In other embodiments, multiple conveyor rollers 120 may be provided at intervals along the first direction, and this application does not limit this.

[0029] Figure 5 A schematic diagram of the cutting assembly 200 is shown, combined with Figure 5In some embodiments, the cutting assembly 200 includes a support frame 220, a first lifting mechanism 230, a cutter assembly 210, and a positioning assembly 240. The support frame 220 has a first platform 221 and a second platform 222, with the second platform 222 disposed on the first platform 221. The first lifting mechanism 230 is connected to the support frame 220 and has a telescopic portion that reciprocates vertically. The second platform 222 is connected to the telescopic portion. The cutter assembly 210 is connected to the bottom surface of the second platform 222 and includes a plurality of cutters 211. The positioning assembly 240 is connected to the second platform 222 and is disposed on the side of the cutter assembly 210 facing the feeding assembly 100. After the sheet metal is conveyed to a set length by the feeding assembly 100, the feeding assembly 100 is stopped. The first lifting mechanism 230 drives the second platform 222 to move down, and the positioning assembly 240 abuts against the sheet metal to fix at least a part of the sheet metal on the first platform 221. The sheet metal is then cut by the corresponding cutter 211 to form the panel to be formed.

[0030] Combination Figure 5 In some embodiments, the top surfaces of the first platform 221 and the plurality of conveying rollers 120 are located on the same plane to ensure that the sheet metal can be smoothly conveyed to the cutting assembly 200 and the bending assembly 300. The support frame 220 is provided with a channel extending along a first direction. The bottom surface of the channel is configured as the first platform 221. The first lifting mechanism 230 can be a hydraulic cylinder connected to the top surface of the channel. A second platform 222 is connected to the piston rod of the hydraulic cylinder. Driven by the hydraulic cylinder, the second platform 222 rises and falls within the channel, simultaneously driving the positioning assembly and the cutting assembly 210 to rise and fall. To ensure the lifting direction of the second platform 222, first guide grooves 223 are provided on both sides of the channel in a second direction. The two ends of the second platform 222 are slidably disposed within the first guide grooves 223, thereby guiding the lifting direction of the second platform 222 and ensuring its proper lifting direction.

[0031] Combination Figure 5In some embodiments, the positioning component 240 includes a first rod 241, a second rod 242, and a third elastic member 243. The first rod 241 is connected to the bottom surface of the second platform 222; the top end of the second rod 242 is retractably inserted into the bottom of the first rod 241; the third elastic member 243 is sleeved around the periphery of the first rod 241 and the second rod 242; the top end of the third elastic member 243 is connected to the top surface of the second platform 222 or the first rod 241; and the bottom end of the third elastic member 243 is connected to the second rod 242. When the second platform 222 is driven to descend using the first lifting mechanism 230 to position the sheet metal, the second rod 242 abuts against the top surface of the sheet metal, controlling the first lifting mechanism 230 to continue operating. The second rod 242 moves inward toward the first rod 241 to the corresponding stroke, simultaneously compressing the third elastic member 243. That is, the second rod 242 is in elastic contact with the sheet metal, avoiding contact disruption and potential loss of the sheet metal. For example, multiple positioning components 240 are provided, and the multiple positioning components 240 are spaced apart along the second direction on the bottom surface of the second platform 222. In other configurations, the multiple positioning components 240 may also be arranged in an array on the bottom surface of the second platform 222, and this application does not limit this.

[0032] Figure 6 A schematic diagram of the cutter assembly 210 is shown. (Combined with...) Figure 6 In some embodiments, the cutter assembly 210 further includes a cutter frame 212 and a second lifting mechanism 214. The cutter frame 212 is connected to the bottom surface of the second platform 222. Multiple conveying channels 213 are spaced apart along a first direction at the bottom of the cutter frame 212. The second lifting mechanism 214, the cutter 211, and the conveying channels 213 are arranged in a one-to-one correspondence. The second lifting mechanism 214 is connected to the cutter frame 212 and has a telescopic portion that reciprocates vertically. The cutter 211 is connected to the output portion of the second lifting mechanism 214 so that it passes through the corresponding conveying channel 213 under the drive of the second lifting mechanism 214. When cutting sheet metal of different compositions, a corresponding cutter 211 can be used to cut it, ensuring cutting quality and efficiency. For example, the second lifting mechanism 214 can adopt a ball screw structure to have strong and stable driving force and precision, ensuring cutting quality. To ensure the lifting direction of the cutter 211, the cutter frame 212 is provided with second guide grooves 215 on both sides in the second direction. The two ends of the cutter 211 are respectively slidably disposed in the second guide grooves 215, thereby guiding the lifting direction of the cutter 211 and thus ensuring the lifting direction of the cutter 211.

[0033] Combination Figure 1In some embodiments, the bending assembly 300 includes a worktable 310 and a press 320. A support mold 330 is connected to the top surface of the worktable 310. The press 320 has an output section that reciprocates vertically. A forming mold 340 is located above the support mold 330 and connected to the output section of the press 320. After the sheet metal is cut into panels using a cutting assembly, the panels are positioned on the support mold 330. Subsequently, the press 320 is started, and the press 320 drives the forming mold 340 to press the panels onto them, thereby forming the panels into fire doors.

[0034] Combination Figure 1 In some embodiments, the height of the workbench 310 is slightly lower than that of the first platform 221. When the forming mold 340 is assembled on the workbench 310, the top surface of the forming mold 340 and the top surface of the first platform 221 are at the same height to facilitate the conveying of the sheet metal. In addition, the bending assembly 300 also includes second legs 313. Multiple second legs are respectively disposed on both sides of the bottom of the workbench 310 in a second direction, so that the bottom of the workbench 310 has a receiving space, and the base of the press 320 is disposed in the receiving space at the bottom of the workbench 310.

[0035] In some embodiments, the top surface of the supporting mold 330 has a closed forming groove, and the bottom surface of the forming mold 340 has a forming protrusion. When the panel is positioned on the top surface of the supporting mold 330, the press 320 is started, and the press 320 drives the forming mold 340 to press onto the panel. The forming protrusion embeds part of the panel into the forming groove, thereby forming the panel into a fire door. In other embodiments, the supporting mold 330 and the forming mold 340 may be provided according to the shape of the fire door, and this application does not limit this.

[0036] In the actual production of fire doors, different shapes of fire doors require different support molds 330 and forming molds 340. The long mold replacement time is a particularly prominent issue, severely restricting further improvements in production efficiency. Currently, most molds and the main equipment body use a rigid connection structure. When processing fire doors of different specifications and models, operators must first use special tools to disassemble the fixing bolts, positioning pins, and other components of the original mold, then precisely align and re-tighten the new mold. This entire process often takes 2-4 hours. During this period, the equipment is completely shut down and cannot perform any processing operations. For multi-variety, small-batch production orders, frequent mold replacements significantly shorten the effective operating time of the equipment, disrupt the production cycle, reduce overall production efficiency, and increase manual debugging costs. Furthermore, the lengthy mold replacement process demands a high level of skill from operators. Insufficient alignment accuracy during debugging may affect the processing quality of subsequent workpieces, leading to product scrap. Based on this, this application further improves the bending component 300.

[0037] Figure 7 A schematic diagram of the structural layout of the workbench 310 is shown. (Combined with...) Figure 1 as well as Figure 7 In some embodiments, the bending assembly 300 further includes a first limiting member 350 and two second limiting members 360. The first limiting member 350 is disposed on the worktable 310 and located on the side of the supporting mold 330 away from the feeding assembly 100, so as to limit the supporting mold 330 in the first direction. Two second limiting members 360 are disposed opposite each other along the second direction, and the two second limiting members 360 are respectively disposed on both sides of the supporting mold 330 in the second direction. The first limiting member 350, the two second limiting members 360 and the support frame 220 enclose a positioning frame adapted to the supporting mold 330, and the supporting mold 330 is positioned within the positioning frame.

[0038] Combination Figure 1 as well as Figure 7 To facilitate the assembly and disassembly of the support mold 330 on the worktable 310, in some embodiments, the first limiting member 350 can reciprocate along a first direction, with one end of the support mold 330 in the first direction abutting against the cutting assembly 200, and the other end of the support mold 330 in the first direction abutting against the first limiting member 350; the second limiting member 360 is vertically connected to the worktable 310, with both sides of the support mold 330 in the second direction abutting against the two second limiting members 360 respectively. When it is necessary to remove the support mold 330 from the worktable 310, the first limiting member 350 is controlled to move away from the support mold 330, and the two second limiting members 360 are recessed into the top surface of the worktable 310, thereby allowing the support mold 330 to be unlocked from the top surface of the worktable 310, and the support mold 330 can be removed from the worktable 310 by means of a lifting device or other mechanism.

[0039] Combination Figure 7In some embodiments, the first limiting member 350 includes a second motor 351, a first screw 352, a slider 353, and a first limiting block 354. The first motor 351 is connected to the worktable 310, and the first screw 352 is drivenly connected to the output of the drive motor. The first screw 352 is rotatably disposed in a third slide groove 311 opened on the top surface of the worktable 310, and the third slide groove 311 extends along a first direction. The slider 353 is threadedly connected to the first screw 352 and is slidably disposed in the first slide groove 351. In the middle, the first limiting block 354 and the slider 353 are connected. Under the drive of the second motor 351, the first limiting block 354 is reciprocated along the first direction and is disposed on the worktable 310.

The second screw 362 is disposed vertically in the fourth slide groove 312 and is rotatably connected to the worktable 310. The second screw 362 and the third motor 361 are connected by transmission. The second limiting block 363 is disposed vertically in the fourth slide groove 312, and at least a portion of the second limiting block 363 protrudes from the top surface of the worktable 310. By controlling the rotation of the third motor 361, the third motor 361 drives the second screw 362 to rotate, which in turn drives the second limiting block 363 to move in the fourth slide groove 312, so that the second limiting block 363 protrudes from the top surface of the worktable 310 to limit the displacement of the support mold 330 in the second direction; or, it is recessed into the top surface of the worktable 310 to release the restriction of the support mold 330 in the second direction, so as to facilitate the disassembly of the support mold 330.

[0042] Combination Figure 8In some embodiments, a third motor 361 is connected to the bottom of a fourth groove 312. The output shaft of the third motor 361 is connected to a drive wheel 364. A gear ring 365 is connected to the circumferential surface of the second screw 362. The gear ring 365 meshes with the drive wheel 364 so that the drive wheel 364 rotates synchronously under the drive of the third motor 361, thereby driving the gear ring 365 and the second screw 362 to rotate.

[0043] Combination Figure 8 In some embodiments, the second limiting member 360 further includes a third telescopic rod 366 and a fourth elastic member 367. The third telescopic rod 366 is arranged vertically, with its bottom end connected to the bottom of the fourth sliding groove 312 and its top end connected to the second limiting block 363. The fourth elastic member 367 is sleeved on the third telescopic rod 366, with its bottom end connected to the bottom of the fourth sliding groove 312 and its top end connected to the second limiting block 363. When the third motor 361 drives the second limiting block 363 to reciprocate in the fourth sliding groove 312, the third telescopic rod 366 extends and retracts synchronously to guide the movement of the second limiting block 363, and the fourth elastic member 367 deforms synchronously. Exemplarily, two third telescopic rods 366 are provided, and the two third telescopic rods 366 are arranged opposite each other on both sides of the second screw 362 along a first direction. In other configurations, each side of the top surface of the worktable 310 in the second direction may also be provided with multiple second limiting members 360 to limit the displacement of the supporting mold 330 in the second direction. Figure 9 A schematic diagram showing the arrangement of the support platform 370 of the bending assembly 300 is provided. Figure 10 It shows Figure 9 Another structural diagram from the perspective of Figure 11 It shows Figure 9 The explosion diagram, combined with Figures 9-11 In some embodiments, the bending assembly 300 further includes a support platform 370, which is disposed above the worktable 310. The support platform 370 is connected to the output section of the press 320. The support platform 370 has a built-in receiving cavity 371, and an opening 372 is provided at the bottom of the support platform 370. A forming mold 340 is disposed within the receiving cavity 371, and the bottom of the forming mold 340 protrudes from the opening 372. Under the action of the press 320, the support platform 370 moves synchronously with the output section of the press 320. Correspondingly, the forming mold 340 also moves synchronously. The press 320 drives the forming mold 340 to press onto the panel, so that the panel is formed into a fire door.

[0044] Combination Figures 9-11In some embodiments, to facilitate the assembly and disassembly of the molding die 340, a fifth sliding groove 373 is provided at the bottom of the support platform 370. The molding die 340 can be vertically movably disposed within the receiving cavity 371. An opening 372 protrudes from the bottom of the molding die 340, and the fifth sliding groove 373 is disposed opposite to each other on both sides of the opening 372 along the second direction. In addition, a disassembly channel 374 is provided on the side of the worktable 310 along the second direction. The second limiting block 363 and the fifth sliding groove 373 are provided in a one-to-one correspondence. The second limiting block 363 can pass through the corresponding fifth sliding groove 373 to lift the molding die 340. After the molding die 340 is lifted, it is pulled out of the receiving cavity 371 through the disassembly channel 374. In practice, when disassembling the molding mold 340, the press 320 drives the support platform 370 to move down to the top surface of the worktable 310, and controls the third motor 361 to start. The third motor 361 drives the second limit block 363 to rise through the second screw 362. The second limit block 363 passes through the corresponding fifth slide groove 373 to lift the molding mold 340, so that the molding mold 340 is at the same height as the disassembly channel 374. The operator can use external tools to pull the molding mold 340 out through the disassembly channel 374, which is convenient, quick and easy.

[0045] Combination Figure 9 as well as Figure 10 In some embodiments, the bending assembly 300 also includes a fourth telescopic rod 380. The fourth telescopic rod 380 is connected between the same corner of the support platform 370 and the worktable 310. During the process of the press 320 driving the support platform 370 to rise and fall, the fourth telescopic rod 380 rises and falls synchronously to ensure the rising and falling direction of the support platform 370 and the forming mold 340 located in the support platform 370.

[0046] Combination Figures 9-11 In some embodiments, since the forming mold 340 moves vertically within the receiving cavity 371 of the support platform 370, it is necessary to lock the forming mold 340 within the support platform 370 to ensure forming quality. Based on this, the bending assembly 300 of this application further includes a locking member 390, which includes a locking screw 391 and a cam 392. The locking screw 391 is threadedly connected to the support platform 370 and is located above the forming mold 340. The cam 392 is connected to the locking screw 391 and is placed within the receiving cavity 371. The cam 392 can rotate to the top surface of the forming mold 340 to press against the forming mold 340, thereby locking the forming mold 340 within the support platform 370; alternatively, the cam 392 can be separated and rotated onto the forming mold 340 to unlock the forming mold 340.

[0047] Combination Figures 9-11In some embodiments, to ensure the locking effect of the molding die 340, a locking groove 375 is provided on the top surface of the molding die 340. A cam 392 and a locking groove 375 are correspondingly provided. The cam 392 can rotate into or out of the corresponding locking groove 375. When the cam 392 rotates into the locking groove 375, the cam 392 presses against the molding die 340, locking the molding die 340 within the support platform 370. When the cam 392 rotates out of the corresponding locking groove 375, the cam 392 separates from the molding die 340, thus unlocking the molding die 340.

[0048] Combination Figures 9-11 In some embodiments, the locking screw 391 extends along a second direction and has an operating end protruding from the support platform 370, allowing operators to operate the locking screw 391 using a wrench or similar component. Additionally, multiple locking screws 391 may be provided. In other configurations, the locking screw 391 may also extend along a first direction; this application does not impose any limitations on this.
