Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically a multi-functional sheet metal bending machine with safety protection function. Background Technology

[0002] Protecting sheet metal bending machines is primarily to ensure the safety of operators and prevent accidental injuries during machine operation. Simultaneously, protection can reduce equipment damage caused by misoperation or malfunction, ensuring production efficiency and product quality, thereby guaranteeing the safety, efficiency, and stability of the entire bending process.

[0003] Existing sheet metal bending machines have significant shortcomings in their safety design. Their safety measures mainly focus on the bending process, using movable guardrails or covers to prevent operators' hands or other body parts from accidentally entering the bending area and thus avoiding injury. However, this design neglects the safety needs of the equipment when it is not in use. When the bending machine is in standby or ready state, its sharp blades and potentially moving parts still pose a threat to nearby personnel. Therefore, we propose a multi-functional sheet metal bending machine with safety protection functions. Utility Model Content

[0004] One of the technical problems this application aims to solve is that protection is only provided during the bending process, and not when the object is not bent.

[0005] To address the aforementioned technical problems, this application provides a multi-functional sheet metal bending machine with safety protection functions, including a base, and further comprising:

[0006] A base frame is provided on top of a base. A curved groove is provided on the top of the base frame. A top frame is provided on the top of the base frame. A cutter head is provided at the bottom of the top frame. The cutter head cooperates with the curved groove to perform bending.

[0007] A frame is provided on top of the base. One side of the top frame is slidably connected to the frame. A hydraulic cylinder is provided inside the frame. The drive end of the hydraulic cylinder is welded to the top frame and is used to drive the top frame to descend and bend.

[0008] The protective unit is respectively installed outside the base frame. The protective unit is provided with a first toothed plate, a second toothed plate and a protective plate. The first toothed plate and the second toothed plate are linked to drive the protective plate to rise and fall, thereby providing shielding and protection.

[0009] In some embodiments, the protective unit includes a first limiting plate disposed on the outer side of the base frame, a first toothed plate slidably connected to the inner side of the first limiting plate, the top end of the first toothed plate being fixedly connected to the outer side of the top frame, a second limiting plate being fixedly connected to the outer side of the base frame, a second toothed plate slidably connected to the inner side of the second limiting plate, the first toothed plate and the second toothed plate being disposed opposite to each other, a protective plate being fixedly connected to the top end of the second toothed plate, the first limiting plate, the first toothed plate, the second limiting plate and the second toothed plate being configured as two sets, the two sets being disposed opposite to each other, the protective plate being disposed between the two second toothed plates, and a connector being disposed between the first toothed plate and the second toothed plate for connecting the first toothed plate and the second toothed plate.

[0010] In some embodiments, the connector includes a fixed frame disposed on the outside of the base frame, and a gear is rotatably connected inside the fixed frame. The gear meshes with a first toothed plate and a second toothed plate respectively. The connector is configured in two sets, which are respectively disposed on both sides of the base frame.

[0011] In some embodiments, a locking unit is provided at the bottom of the base frame for driving the locking block to rise and fall and triggering a touch switch, thereby locking the gear and stopping the descent of the top frame.

[0012] In some embodiments, the locking unit includes a locking member disposed on the outside of the base frame for locking the gear, and a driving member is disposed at the bottom of the base frame for driving the lifting rod to rise and fall and triggering a touch switch, thereby locking the gear and stopping the top frame from descending.

[0013] In some embodiments, the locking element includes a lifting rod disposed on the outside of the base frame, the lifting rod being slidably connected to the outside of the fixed frame, a connecting block being fixedly connected to the top of the lifting rod, and a plurality of locking blocks being disposed at the bottom of the connecting block.

[0014] In some embodiments, the driving component includes a first rotating shaft rotatably connected to the bottom end of the lifting rod, a support frame is provided on the top of the base, a connecting rod is rotatably connected to the top of the support frame, one end of the connecting rod is rotatably connected to the first rotating shaft, a foot pedal is provided on the top of the base, a telescopic rod is provided at the bottom of the foot pedal, four positioning rods are provided at the bottom of the foot pedal, all four positioning rods are inserted into the base, a second rotating shaft is provided on the outer side of the base, the outer end of the second rotating shaft is rotatably connected to the other end of the connecting rod, and a touch switch is provided on the top of the base for stopping the descent of the top frame. The first rotating shaft, support frame, connecting rod and second rotating shaft are configured as two sets, which are arranged opposite to each other on both sides of the foot pedal.

[0015] This utility model has at least the following beneficial effects:

[0016] By setting up a protective unit, the protective plate can rise to open up space while the cutter head descends, making bending easier. Once the cutter head rises, the protective plate will descend simultaneously to prevent accidents caused by accidentally putting a hand between the cutter head and the groove when bending is not being performed.

[0017] By setting a locking unit, the top frame and cutter head will only descend when the foot pedal is continuously pressed. Once the foot pedal is released, the locking block will immediately descend and lock the gear. At the same time, the touch switch will be released, the hydraulic cylinder will stop immediately, and the top frame will stop descending immediately. In this way, bending can only be performed by concentrating on pressing the foot pedal, avoiding accidents caused by the cutter head descending simultaneously due to lack of concentration during bending. In addition, if a bending error occurs, the foot pedal can be released immediately to stop bending.

[0018] In summary, by setting up protective and locking units, two functions of protection can be provided to protect the equipment both when it is not bent and when it is bending, thus preventing accidents caused by equipment malfunctions. Attached Figure Description

[0025] 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. Example 1

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A multi-functional sheet metal bending machine with safety protection function includes a base 1, a base frame 2, a frame 3, and a protective unit 4. The base frame 2 is located on top of the base 1, and a bending groove 21 is provided on the top of the base frame 2. A top frame 22 is provided on the top of the base frame 2, and a cutter head 23 is provided at the bottom of the top frame 22. The cutter head 23 cooperates with the bending groove 21 to perform bending. The frame 3 is located on top of the base 1, and one side of the top frame 22 is slidably connected to the frame 3. A hydraulic cylinder 31 is provided inside the frame 3, and the driving end of the hydraulic cylinder 31 is welded to the top frame 22 to drive the top frame 22 to descend for bending. The protective unit 4 is located outside the base frame 2. The protective unit 4 is provided with a first toothed plate 42, a second toothed plate 44, and a protective plate 45. The first toothed plate 42 and the second toothed plate 44 are linked to drive the protective plate 45 to rise and fall, thereby providing shielding protection.

[0028] The protective unit 4 includes a first limiting plate 41 disposed on the outside of the base frame 2. A first toothed plate 42 is slidably connected to the inside of the first limiting plate 41. The top end of the first toothed plate 42 is fixedly connected to the outside of the top frame 22. A second limiting plate 43 is fixedly connected to the outside of the base frame 2. A second toothed plate 44 is slidably connected to the inside of the second limiting plate 43. The first toothed plate 42 and the second toothed plate 44 are arranged opposite to each other. A protective plate 45 is fixedly connected to the top end of the second toothed plate 44. The first limiting plate 41, the first toothed plate 42, the second limiting plate 43, and the second toothed plate 44 are set as two sets, which are arranged opposite to each other. The protective plate 45 is disposed between the two second toothed plates 44. As the cutter head 23 continues to descend and the protective plate 45 continues to rise, the cutter head 23 and the groove 21 will eventually engage to bend the workpiece, while the protective plate 45 rises to its limit, and vice versa.

[0029] The connector 46 includes a fixed frame 461 disposed on the outside of the base frame 2. A gear 462 is rotatably connected inside the fixed frame 461. The gear 462 meshes with the first toothed plate 42 and the second toothed plate 44 respectively. The connector 46 is configured in two sets, which are respectively disposed on both sides of the base frame 2. The fixed frame 461 is fixedly connected to the outside of the base frame 2 through a fixed connection, which facilitates disassembly.

[0030] In use, the hydraulic cylinder 31 drives the top frame 22 to descend, which in turn drives the cutter head 23 to descend. At the same time, the descent of the top frame 22 causes the first toothed plate 42 to descend through the limit of the first limiting plate 41, which in turn drives the gear 462 to rotate. The gear 462 then drives the second toothed plate 44 to rise in the opposite direction, thereby driving the protective plate 45 to rise. At this time, the workpiece can be inserted between the cutter head 23 and the curved groove 21. As the cutter head 23 continues to descend and the protective plate 45 continues to rise, the cutter head 23 and the curved groove 21 will eventually fit together to bend the workpiece, and the protective plate 45 will rise to its limit. Conversely, when the top frame 22 rises back to its original position, the protective plate 45 will descend accordingly, which can cover the cutter head 23 and the curved groove 21 to prevent the hand from reaching in and causing an accident. Example 2

[0031] Please see Figure 4 This utility model provides a technical solution:

[0032] Unlike Embodiment 1, the bottom of the base frame 2 is provided with a locking unit 5, which is used to drive the locking block 513 to rise and fall and trigger the touch switch 528, thereby locking the gear 462 and stopping the descent of the top frame 22.

[0033] The locking unit 5 includes a locking member 51 disposed on the outside of the base frame 2 for locking the gear 462. The locking member 51 includes a lifting rod 511 disposed on the outside of the base frame 2. The lifting rod 511 is slidably connected to the outside of the fixed frame 461. A connecting block 512 is fixedly connected to the top of the lifting rod 511. Multiple locking blocks 513 are disposed at the bottom of the connecting block 512. The locking blocks 513 are made of hard rubber to avoid hard contact with the gear 462 and damage to the gear 462. At the same time, the hard rubber can effectively block the rotation of the gear 462.

[0034] A drive unit 52 is provided at the bottom of the base frame 2 to drive the lifting rod 511 to rise and fall and to trigger the touch switch 528, thereby locking the gear 462 and stopping the top frame 22 from descending. The drive unit 52 includes a first rotating shaft 521 rotatably connected to the bottom end of the lifting rod 511. A support frame 522 is provided at the top of the base 1. A connecting rod 523 is rotatably connected to the top of the support frame 522. One end of the connecting rod 523 is rotatably connected to the first rotating shaft 521. A foot pedal 524 is provided at the top of the base 1. A telescopic rod 525 is provided at the bottom of the foot pedal 524. Four positioning rods 526 are provided at the bottom of the foot pedal 524. All four positioning rods 526 are inserted into the base 1. The outer side of the base 1 is provided with A second rotating shaft 527 is provided, the outer end of which is rotatably connected to the other end of the connecting rod 523. A touch switch 528 is provided on the top of the base 1 to stop the descent of the top frame 22. The first rotating shaft 521, the support frame 522, the connecting rod 523 and the second rotating shaft 527 are set in two sets, which are arranged opposite each other on both sides of the foot pedal 524. It should be noted that both ends of the connecting rod 523 can be extended and retracted, and can extend and retract accordingly with the rotation of the first rotating shaft 521 and the second rotating shaft 527 to avoid breakage. In addition, the telescopic rod 525 provides elasticity for the foot pedal 524 to return to its original position. The telescopic rod 525 is provided with a damping structure, which is existing technology and will not be described in detail here.

[0035] Before bending, the foot pedal 524 needs to be pressed down, causing it to descend. This descent of the foot pedal 524 lowers the second rotating shaft 527, which in turn rotates the connecting rod 523. The connecting rod 523 then rotates the first rotating shaft 521, which in turn raises the lifting rod 511. This causes the connecting block 512 and multiple locking blocks 513 to rise synchronously, disengaging the locking blocks 513 from the gear 462, allowing the gear 462 to rotate. Simultaneously, the descent of the foot pedal 524 triggers an actuation mechanism. Switch 528 is activated, and hydraulic cylinder 31 is driven only when switch 528 is triggered. This ensures two safety measures are in place, allowing the top frame 22 to descend and the protective plate 45 to rise. Once foot pedal 524 is released, locking block 513 will immediately descend and lock gear 462. At the same time, when switch 528 is released, hydraulic cylinder 31 will immediately stop, and the top frame 22 will immediately stop descending. Thus, bending can only be performed by concentrating on stepping on foot pedal 524, preventing accidents caused by carelessness leading to hands reaching in and the blade 23 descending simultaneously.
