Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, and in particular to a metal sheet bending auxiliary device with automatic positioning. Background Technology

[0002] Sheet bending is a metal processing technique that refers to the process of bending metal sheets into shape according to a predetermined angle using a special bending machine or bending die. This processing method is widely used in the manufacture of metal structural parts, such as chassis, cabinets, metal furniture, and architectural decorative parts. Sheet bending can achieve the processing of various geometric shapes, including right-angle bending and arc bending.

[0003] When bending metal sheets, a bending machine is required. To use the machine, the sheet is placed on a mold inside the bending machine, and then the bending blade inside the machine presses down, causing the sheet to engage with the groove in the mold, thus completing the bending of the sheet.

[0004] When bending existing sheet materials, it is necessary to plan the bending points in advance and then use a positioning component to align the bending points with the mold to ensure accurate bending. However, when bending sheet materials, it is usually necessary to repeatedly bend the same side of the sheet material. Since existing positioning components are usually at a fixed angle, the already bent, inclined part of the sheet material cannot properly engage with the positioning component during a second bend, which affects the bending effect and makes it inconvenient to use.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present utility model. This embodiment provides a metal plate bending auxiliary device with automatic positioning, including a mold 1, a fixing box 2 installed below the mold 1, a positioning component 3 inside the fixing box 2, and an tilting component 4 on the upper surface of the fixing box 2.

[0030] The positioning component 3 includes a bidirectional threaded rod 302 movably connected inside the fixed box 2. Two threaded sleeves 303 are engaged with the outer surface of the bidirectional threaded rod 302. An mounting block 301 is installed on the outer surface of the threaded sleeves 303. A rotating rod 306 is hinged to the side of the mounting block 301. A connecting block 307 is hinged to the end of the rotating rod 306 away from the mounting block 301.

[0031] Specifically, a worm gear 305 is installed on the outer surface of one end of the bidirectional threaded rod 302, and a worm 304 is movably connected inside the fixed box 2. The worm 304 is meshed with the worm gear 305. A motor is installed inside the fixed box 2, and the output end of the motor is connected to one end of the worm 304 for transmission. Through the unidirectional transmission characteristics of the worm gear 305 and the worm 304, the tilting component 4 is prevented from shifting.

[0032] Specifically, the upper surface of the fixed box 2 is provided with a sliding groove that cooperates with the connecting block 307. The sliding groove is used to limit the stable movement of the connecting block 307 and prevent the moving block from being misaligned.

[0033] Furthermore, a slider is provided on the lower surface of the mounting block 301, and a slide rail that cooperates with the slider is installed at the bottom of the inner cavity of the fixed box 2. By setting the moving block and the slide groove, and cooperating with the slider and the slide rail, the mounting block 301 is limited to prevent rotation, so that the limiting sleeve cannot rotate. This ensures that the rotation of the bidirectional threaded rod 302 can steadily drive the threaded sleeve 303 to move. The motor drives the bidirectional threaded rod 302 to rotate through the cooperation of the worm 304 and the worm wheel 305. This drives the mounting block 301 to move towards each other on the outer surface of the bidirectional threaded rod 302 through the threaded sleeve 303, thereby driving the rotating rod 306 to rotate. When the rotating rod 306 rotates, it drives the connecting block 307 to move away from the mold 1, thereby driving the moving plate 405 to move. After the moving plate 405 drives the abutment plate 401 to the designated position, the motor stops, thereby limiting the fixed position of the abutment plate 401.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The tilting component 4 includes a movable plate 405 fixedly installed on the top of the connecting block 307. Two fixing blocks 406 are installed on the upper surface of the movable plate 405. Fixing pins 407 are movably connected to the adjacent sides of the two fixing blocks 406. An abutment plate 401 is fixedly installed between the two fixing pins 407. A movable disk 409 is provided inside the fixing block 406. A compression spring 411 is installed on the side of the movable disk 409 away from the abutment plate 401. Ratchets 408 are installed on the adjacent surfaces of the movable disk 409 and the fixing pins 407.

[0036] Specifically, a support rod 402 is hinged to the side of the abutment plate 401 away from the mold 1. A U-shaped plate 403 is hinged to the bottom end of the support rod 402. A limiting groove for sliding the U-shaped plate 403 is provided on the upper surface of the moving plate 405. A compression spring 404 is installed between the U-shaped plate 403 and the inner wall of the limiting groove away from the mold 1. A slide rail is also provided at the bottom of the inner cavity of the limiting groove. A slider that cooperates with the slide rail is installed on the lower surface of the U-shaped plate 403, so that the U-shaped plate 403 can slide in the limiting groove. The U-shaped plate 403 is positioned to move towards the mold 1, thereby maintaining the auxiliary support of the support rod 402 on the abutment plate 401. When the U-shaped plate 403 slides in the limiting groove to the side close to the mold 1, the abutment plate 401 can remain vertical. The rotation lock of the fixing pin 407 is achieved through the cooperation of the two ratchet wheels 408. When bending, the side of the abutment plate 401 close to the mold 1 will be squeezed by the plate material, so there is no need to consider the auxiliary support of the side of the abutment plate 401 close to the mold 1.

[0037] Specifically, a connecting shaft 410 is installed on the side of the movable disk 409 away from the abutment plate 401. The end of the connecting shaft 410 away from the abutment plate 401 passes through the outer surface of the fixing block 406 and is fitted with a fixing disk. The fixing disk pulls the connecting shaft 410, thereby moving the movable disk 409, which in turn causes the two ratchet wheels 408 to separate, unlocking the fixing pin 407 and facilitating the rotation of the abutment plate 401.

[0038] Specifically, the outer surface of the movable disk 409 is provided with a limiting protrusion, and the interior of the fixing block 406 is provided with a keyway that mates with the limiting protrusion. Through the engagement of the limiting protrusion and the keyway, the movable disk 409 is prevented from rotating, thereby preventing the ratchet 408 on the outer surface of the movable disk 409 from rotating. This prevents the fixing pin 407 from driving the two ratchet 408 to rotate, thus affecting the rotation angle limit of the abutment plate 401. Pulling the pull plates on both sides, the movable disk 409 is driven through the connecting shaft 410. 09 moves, thereby causing the ratchet 408 on the outer surface of the moving disk 409 to separate from the ratchet 408 on the outer surface of the fixing pin 407, thereby unlocking the fixing pin 407 and allowing the abutment plate 401 to rotate. After the abutment plate 401 is rotated to the designated position, the pull plate is released. Under the reset action of the compression spring 411, the ratchet 408 on the outer surface of the moving disk 409 engages with the ratchet 408 on the outer surface of the fixing pin 407, thereby locking the rotation angle of the abutment plate 401.

[0039] Furthermore, the ratchet 408 uses an end-face ratchet 408, and the two ratchet 408 cooperate to lock the rotation direction of the abutment plate 401 away from the mold 1, thereby achieving a limit. When the abutment plate 401 rotates towards the mold 1, the support rod 402 drives the U-shaped plate 403 to slide in the limiting groove on the upper surface of the moving plate 405 to the side closer to the mold 1, thereby limiting the rotation angle of the abutment plate 401 towards the mold 1, which can only rotate to a vertical state at most, preventing the abutment plate 401 from tilting towards the mold 1. The lower surface of the moving plate 405 is provided with a pulley, and the upper surface of the fixed box 2 is provided with a sliding groove, so that when the rotating plate rotates and drives the connecting block 307 to move, it can smoothly drive the moving plate 405 to slide.

[0040] Working principle: When bending a metal sheet, the positioning component 3 is adjusted according to the required bending position, and the motor is started. The motor, through the cooperation of the worm gear 304 and worm wheel 305, drives the bidirectional threaded rod 302 to rotate. This, in turn, drives the mounting block 301 to move towards each other on the outer surface of the bidirectional threaded rod 302 via the threaded sleeve 303. This, in turn, drives the rotating rod 306 to rotate. When the rotating rod 306 rotates, it drives the connecting block 307 to move away from the mold 1, which in turn drives the moving plate 405 to move. After the moving plate 405 moves the abutment plate 401 to the designated position, the motor stops, thus fixing the position of the abutment plate 401. This ensures that during bending, the sheet metal abuts against the outer surface of the abutment plate 401, thereby positioning the designated bending part of the sheet metal. Align the position with the groove of mold 1, and then adjust the angle of the abutment plate 401 according to the bending requirements. Pull the pull plates on both sides, thereby driving the moving plate 409 to move through the connecting shaft 410. This causes the ratchet 408 on the outer surface of the moving plate 409 to separate from the ratchet 408 on the outer surface of the fixing pin 407, thereby unlocking the fixing pin 407 and allowing the abutment plate 401 to rotate. After rotating the abutment plate 401 to the designated position, release the pull plate. Under the reset action of the compression spring 411, the ratchet 408 on the outer surface of the moving plate 409 engages with the ratchet 408 on the outer surface of the fixing pin 407, thereby locking the rotation angle of the abutment plate 401. This facilitates the abutment and limit of the inclined plate surface, and finally completes the bending of the plate.
