Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sheet metal processing, in particular to a multi-directional sheet metal processing positioning device. BACKGROUND

[0002] At present, sheet metal bending processing is mostly manually operated by placing the sheet metal on a platform, controlling the down pressure of the attached blade through a controller, and manually adjusting the position of the sheet metal frequently. The operation of the controller requires certain programming, and manual operation is time-consuming, costly, and dangerous. Moreover, the positioning precision of the sheet metal bending cannot be guaranteed. After the sheet metal bending is completed, the sheet metal needs to be removed and positioned at the next processing station before subsequent processing can be carried out, which is time-consuming and troublesome. Moreover, the irregularly shaped sheet metal after bending cannot be positioned at multiple angles, resulting in serious internal relative displacement during sheet metal processing, which can cause damage to the bending part and processing misalignment. SUMMARY

[0003] The present application aims to solve the problems of traditional sheet metal bending processing, which requires a controller to control the attached blade in combination with manual frequent position adjustment of the sheet metal, certain programming of the controller operation, time-consuming and costly manual operation, dangerous operation, and inability to guarantee the positioning precision of the sheet metal bending. After the sheet metal bending is completed, the sheet metal needs to be removed and positioned at the next processing station before subsequent processing can be carried out, which is time-consuming and troublesome. Moreover, there is no multi-angle positioning device for irregularly shaped sheet metal after bending, resulting in serious internal relative displacement during sheet metal processing, which can cause damage to the bending part and processing misalignment. The present application provides a multi-directional sheet metal processing positioning device.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a multi-directional sheet metal processing positioning device, comprising a device base, a clamping device, and a plurality of bending devices. The clamping device comprises a clamping base, a rotating beam hinged to the clamping base, a clamping structure fixed to the lower right end of the rotating beam, and a pressure plate provided at the left end of the rotating beam. A clamping plate is provided in the clamping structure. The clamping plate is slidably connected in the corresponding arc-shaped sliding groove through a plurality of telescopic sleeve structures. A reset elastic member is provided in the telescopic sleeve structure. A second telescopic rod is provided on the bending device, and the movable end of the second telescopic rod is provided with a pressure plate.

[0005] Further description of the above technical scheme:

[0006] The clamping device and the bending device are fixed to the device base by fasteners. The plurality of bending devices are staggered according to the relative positions and bending angles of different bending surfaces in the sheet metal product design.

[0007] Further description of the above technical scheme:

[0008] The clamping structure includes a structural shell, a movable cavity inside the structural shell, a base plate connected to the movable cavity via a first telescopic rod, and an equally spaced arc-shaped groove on the base plate, with limiting baffles on both sides of the arc-shaped groove.

[0009] As a further description of the above technical solution:

[0010] The telescopic sleeve structure includes a telescopic tube and a sleeve. A slider is provided at one end of the telescopic tube, and the slider is slidably connected in an arc-shaped groove. A limiting block is provided at the other end of the telescopic tube opposite to the slider and is connected in the sleeve. A sealing plate corresponding to the limiting block is provided at the end of the sleeve near the slider.

[0011] As a further description of the above technical solution:

[0012] One end of the reset elastic element is fixed to the clamping plate, while the other end is fixed to the limiting block.

[0013] As a further description of the above technical solution:

[0014] The bending device includes a U-shaped support, a J-shaped rotating rod hinged to the right end of the U-shaped support, and connecting side plates hinged to both sides of the bending point of the J-shaped rotating rod. The other end of the connecting side plate relative to the J-shaped rotating rod is hinged to the right end of the second telescopic rod, and the second telescopic rod is threaded in the limiting sleeve at the left end of the U-shaped support.

[0015] As a further description of the above technical solution:

[0016] The device also has a handle on its base.

[0017] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. This sheet metal processing positioning device clamps one end of the sheet metal using a clamping device, and then the first bending point is bent by the abutment and compression of two adjacent bending devices. Simultaneously, due to the flexible and automatic angle adjustment of the clamping device, it automatically adjusts according to changes in the sheet metal's angle, ensuring stable clamping and positioning at one end of the sheet metal. The bending devices can then be driven sequentially from near to far to perform bending processing on the sheet metal. After bending, the sheet metal is in a multi-directional fixed state, eliminating the need to remove it. Subsequent processing steps such as grinding, drilling, and welding can continue. This eliminates the need for sheet metal removal, transfer, and subsequent positioning operations, making the operation simple and time-saving. The sheet metal bending operation is simple, the bending process is seamless, and the precision meets requirements. Unlike traditional sheet metal bending processes, it eliminates the need for frequent position adjustments, which are time-consuming and result in lower sheet metal precision.

[0019] 2. By adjusting the extension and retraction of the first telescopic rod, the telescopic tubes and sleeves at different positions, in conjunction with the reset elastic element, achieve stepped length adjustment of the telescopic sleeve structure. The slider of the telescopic tube and the arc-shaped groove are angled to better accommodate changes in the sheet metal angle, ensuring stable positioning of the sheet metal by the clamping device. By rotating the J-shaped rotary rod, the bending device can be switched from a relaxed state to a locked state. Adjacent bending devices interlock and press the two sides of the sheet metal to form the shape. The structure is simple and the operation is convenient. 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.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0034] Please see Figures 1-9This invention provides a technical solution: a multi-directional sheet metal processing positioning device, including a device base 1, a clamping device 2, and multiple bending devices 3. The clamping device 2 includes a clamping base 21, a rotating beam 22 hinged to the clamping base 21, a clamping structure 23 fixed to the lower right end of the rotating beam 22, and a pressure plate 24 disposed at the left end of the rotating beam 22. A clamping plate 236 is disposed within the clamping structure. The clamping plate 236 is slidably connected to a corresponding arc-shaped slide groove 233 through multiple sets of telescopic sleeve structures. A reset elastic element 237 is disposed within the telescopic sleeve structure. A second telescopic rod 34 is disposed on the bending device 3. A pressure plate 35 is disposed at the movable end of the second telescopic rod 34. This sheet metal processing positioning device clamps one end of the sheet metal through the clamping device, and then through two adjacent... The pressing and squeezing of the bending device causes the first bending point to bend and form. At the same time, due to the flexible and automatic angle adjustment of the clamping device, it automatically adjusts according to the angle change of the sheet metal, so that the clamping and positioning of one end of the sheet metal is stable. Then, the bending device can be driven sequentially from near to far to bend the sheet metal. After the sheet metal is bent, the sheet metal is in a multi-directional fixed state. There is no need to remove the sheet metal, and subsequent processing steps such as grinding, drilling, and welding can continue. This eliminates the need for sheet metal removal and transfer, as well as the sheet metal positioning operation for subsequent processing steps. The operation is simple and time-saving. The sheet metal bending operation is simple, the bending and forming is completed in one go, and the accuracy meets the requirements. Unlike traditional sheet metal bending processing, there is no need for frequent position adjustments of the sheet metal, which is time-consuming and has low sheet metal precision.

[0035] Both the clamping device 2 and the bending device 3 are fixed to the device base 1 by fasteners. Multiple bending devices 3 are staggered according to the relative positions and bending angles of different bending surfaces in the sheet metal finished product design, so that the sheet metal bending effect is optimal and meets the sheet metal processing requirements.

[0036] The clamping structure 23 includes a structural shell, a movable cavity is provided inside the structural shell, a base plate 232 is connected to the movable cavity through a first telescopic rod 231, and an arc-shaped sliding groove 233 is provided on the base plate 232 at equal intervals. Limiting baffles are provided on both sides of the arc-shaped sliding groove 233, so that the angle adjustment of the clamping structure is smoother and more stable.

[0037] The telescopic sleeve structure includes a telescopic tube 234 and a sleeve 235. A slider is provided at one end of the telescopic tube 234, and the slider is slidably connected in the arc-shaped groove 233. A limiting block 238 is provided at the other end of the telescopic tube 234 opposite to the slider and is connected in series in the sleeve 235. A sealing plate 239 corresponding to the limiting block 238 is provided at the end of the sleeve 235 near the slider, so that the length adjustment of the abutment structure in the clamping structure is more stable and faster.

[0038] One end of the reset elastic element 237 is fixed to the clamping plate 236 and the other end is fixed to the limiting block 238, making the telescopic sleeve structure extend and retract more quickly and stably.

[0039] The bending device 3 includes a U-shaped support 31, a J-shaped rotating rod 32 hinged to the right end of the U-shaped support 31, and connecting side plates 33 hinged to both sides of the bending point of the J-shaped rotating rod 32. The other end of the connecting side plate 33 relative to the J-shaped rotating rod 32 is hinged to the right end of the second telescopic rod 34. The second telescopic rod 34 is threaded in the limiting sleeve at the left end of the U-shaped support 31, which makes the transition between the relaxed state and the locked state of the bending device faster, and facilitates sheet metal bending processing and removal.

[0040] The device base 1 is also equipped with a handle 4 to facilitate the movement of the device.

[0041] The working principle of a multi-directional sheet metal processing positioning device in this embodiment includes: In use, firstly, the pressure plate 24 is pressed down, causing the rotating beam 22 to rotate along the clamping base 21, and its left end to lift the clamping structure 23, placing the sheet metal in the gap between the clamping plates 236. Then, the first telescopic rod 231 is extended, causing the clamping plates 236 to clamp and position one end of the sheet metal. At this time, the clamping structure 23 is in use state one (e.g., ...). Figure 5 Holding the J-shaped rotating rod 32 of the bending device 3, rotate it to the lower right of the U-shaped support 31, causing the connecting side plate 33 to fit onto the hinge at the right end of the U-shaped support 31. The second telescopic rod 34 is pulled to the right, locking the structure and allowing the bending device 3 to change from its initial state (e.g., ...) to its current state. Figure 8 Switch to usage state two (e.g.) Figure 9 The second telescopic rods 34 on the two bending devices 3 near the clamping device 2 extend by a predetermined amount to complete the first bending point. Simultaneously, the sheet metal orientation changes. The extension amount of the first telescopic rod 231 is adjusted, and the telescopic tube 234 and sleeve 235, in conjunction with the reset elastic element 237, adjust the length of the telescopic sleeve structure. The slider of the telescopic tube 234 and the arc-shaped groove 233 are angled to better accommodate changes in the sheet metal angle, ensuring stable positioning of the sheet metal by the clamping device 2. This is the second usage state of the clamping structure 23 (e.g., ...). Figure 6 Once the sheet metal is positioned at one end, the second telescopic rod 34 on the bending device 3, from near to far, can be activated sequentially to drive the pressure plate 35 to press and squeeze the sheet metal, bending it into shape. After that, since the sheet metal is completely fixed at this point, there is no need to remove it, and subsequent processing steps such as grinding, drilling, and welding can continue.

[0042] In summary, due to the adoption of the above technical solution, the multi-directional sheet metal processing positioning device of this embodiment has the following advantages compared with the prior art:

[0043] 1. This sheet metal processing positioning device clamps one end of the sheet metal using a clamping device, and then the first bending point is bent by the abutment and compression of two adjacent bending devices. Simultaneously, due to the flexible and automatic angle adjustment of the clamping device, it automatically adjusts according to changes in the sheet metal's angle, ensuring stable clamping and positioning at one end of the sheet metal. The bending devices can then be driven sequentially from near to far to perform bending processing on the sheet metal. After bending, the sheet metal is in a multi-directional fixed state, eliminating the need to remove it. Subsequent processing steps such as grinding, drilling, and welding can continue. This eliminates the need for sheet metal removal, transfer, and subsequent positioning operations, making the operation simple and time-saving. The sheet metal bending operation is simple, the bending process is seamless, and the precision meets requirements. Unlike traditional sheet metal bending processes, it eliminates the need for frequent position adjustments, which are time-consuming and result in lower sheet metal precision.
