Technical Field
[0001] This utility model relates to the field of sheet metal bending technology, specifically to a precision sheet metal bending springback compensation and positioning device. Background Technology
[0002] In the industrial manufacturing sector, sheet metal parts are widely used in the automotive, electronics, and machinery industries due to their lightweight structure and good formability. Bending is one of the core processes in sheet metal forming, directly affecting the assembly accuracy and performance of the final product. Currently, sheet metal bending devices on the market mainly consist of support components, bending execution components, and positioning components. However, existing bending devices equipped with spring-type springback suppression components have significant technical limitations when dealing with sheet metal parts of different materials or thicknesses: the compensation force of their springback suppression components is mostly fixed and cannot be adaptively adjusted according to the material characteristics or thickness specifications of the sheet metal parts. When processing highly elastic materials or thicker sheet metal parts, the fixed compensation force is insufficient to offset large springback angle deviations, causing the final bending angle of the sheet metal parts to exceed the tolerance range; while when processing low-elastic materials or thinner sheet metal parts, excessive compensation force can easily cause deformation or surface damage at the bending point of the sheet metal parts, making it impossible to achieve precise springback compensation control. This severely restricts the device's adaptability to processing sheet metal parts of various specifications and materials, making it difficult to meet the mass production needs of high-precision sheet metal parts. Therefore, there is an urgent need for a precision sheet metal bending springback compensation positioning device that can solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Please see Figure 1-7 This utility model provides a technical solution: a precision sheet metal bending springback compensation positioning device, comprising: a base plate 1, which is set on the ground; a support plate 2, which is installed on the base plate 1; and a top plate 3, the top of which is installed on the support plate 2. Before the device is operated, the base plate 1 is first placed firmly on the ground, then the support plate 2 is precisely installed in the preset position of the base plate 1, and finally the top plate 3 is assembled on the top of the support plate 2. The three together form the basic frame of the device, providing stable support for the subsequent installation and operation of each component, thereby ensuring the overall structural stability of the device and greatly improving the device's anti-shaking ability during subsequent processing, avoiding the impact of unstable frame on processing accuracy.
[0019] A bending assembly is mounted on the top plate 3 and is used to bend sheet metal parts at a preset angle. The bending assembly includes a hydraulic cylinder 4 mounted on the top of the top plate 3. The output end of the hydraulic cylinder 4 extends to the bottom of the top plate 3 and is fixedly connected to a bending die 5. When the bending assembly is working, the hydraulic cylinder 4 is activated, and the hydraulic power is output to push its output end downward, which drives the bending die 5 to move downward synchronously. After the bending die 5 contacts the sheet metal part, it bends the sheet metal part according to the preset trajectory, so that the sheet metal part forms the required angle. This achieves the effect of strong bending through hydraulic power, thereby greatly improving the bending force and bending speed of the bending assembly and meeting the bending requirements of sheet metal parts of different thicknesses. The clamping assembly 6 is mounted on the support plate 2 and is used to position and clamp the sheet metal part during the bending process to prevent it from shifting. After the sheet metal part is placed in the working area of the device, the clamping assembly 6 starts to operate. Its internal drive structure drives the clamping components to move closer to the sheet metal part until the sheet metal part is firmly fixed in the preset position. It maintains a stable clamping force throughout the bending process, thereby achieving the effect of effectively positioning and clamping the sheet metal part. This greatly improves the stability of the sheet metal part during the bending process and avoids the decrease in bending accuracy caused by the sheet metal part shifting. The lifting component 7 is mounted on the clamping component 6 and is used to adjust the height of the springback compensation component 8 according to the thickness of the sheet metal part and the bending requirements, so that the springback compensation component 8 is precisely aligned with the bending area of the sheet metal part. When it is necessary to adjust the height of the springback compensation component 8 according to the thickness of the sheet metal part and the bending requirements, the lifting component 7 receives a control signal and starts the internal drive mechanism to move the springback compensation component 8 vertically until the springback compensation component 8 is completely aligned with the bending area of the sheet metal part. This achieves the function of precisely adjusting the height of the springback compensation component 8, thereby greatly improving the correspondence accuracy between the springback compensation component 8 and the bending area of the sheet metal part and ensuring the springback compensation effect. Springback compensation component 8 is mounted on lifting component 7. It is used to apply a preset pressure to the bent part of the sheet metal part after bending to counteract the springback angle deviation caused by the material properties of the sheet metal part. After the bending operation of the sheet metal part is completed, the springback compensation component 8 immediately activates, and its internal elastic component releases pressure, applying a preset pressure to the bent part of the sheet metal part. This pressure continues for a period of time to counteract the springback trend of the sheet metal part, thereby achieving the effect of counteracting the springback angle deviation of the sheet metal part. This greatly improves the final angle accuracy of the sheet metal part after bending and reduces product defects caused by springback. The elastic adjustment component 9 is mounted on the springback compensation component 8 and is used to adjust the amount of elastic compensation applied by the springback compensation component 8 according to the springback characteristics of sheet metal parts of different materials and thicknesses. When processing sheet metal parts of different materials or thicknesses, the operator can adjust the control component of the elastic adjustment component 9 to change the state of its internal transmission structure, thereby adjusting the compression or tension of the elastic component inside the springback compensation component 8, thus changing the amount of elastic compensation. This achieves the function of adjusting the amount of elastic compensation according to the characteristics of the sheet metal parts, thereby greatly improving the adaptability of the device to sheet metal parts of different specifications and expanding the application range of the device. Furthermore, the clamping assembly 6 includes an adjusting plate 601 installed on the inner wall of the support plate 2. Adjusting grooves 603 are provided on both sides of the top of the adjusting plate 601. A first motor 602 is installed on one side of the adjusting plate 601. A rotating shaft 604 is fixedly connected to the output end of the first motor 602. The other end of the rotating shaft 604 extends into the interior of the adjusting plate 601 and is fixedly connected to a drive gear 605. Sliding toothed plates 606 are meshed on both the upper and lower sides of the drive gear 605. Connecting plates 607 are fixedly connected to opposite sides of the two sliding toothed plates 606. The top of the connecting plate 607 extends to the adjusting plate 601 through the adjusting grooves 603. A clamping plate 701 is fixedly connected above the clamping assembly 6. When the clamping assembly 6 is working, the first motor 602 starts and drives the rotating shaft 604 to rotate. The rotating shaft 604 drives the drive gear 605 to rotate inside the adjusting plate 601. The drive gear 605 drives the sliding toothed plates 606 meshing on the upper and lower sides to move relative to each other. The sliding toothed plates 606 drive the clamping plate 701 to move along the adjusting groove 603 through the connecting plate 607. Finally, the clamping plate 701 clamps the sheet metal part, thereby achieving the effect of precise clamping through mechanical transmission. This greatly improves the clamping efficiency and uniformity of clamping force of the clamping assembly 6, and avoids uneven force on the sheet metal part. Furthermore, the lifting assembly 7 includes a lifting groove 702 formed on one side of the clamping plate 701 and a second motor 703 mounted on the top of the clamping plate 701. The output end of the second motor 703 extends into the interior of the lifting groove 702 and is fixedly connected to a lead screw 704. A lead screw nut 705 is slidably connected to the outer surface of the lead screw 704, and a mounting plate 706 is fixedly connected to one side of the lead screw nut 705. When the lifting assembly 7 adjusts its height, the second motor 703 starts, driving the lead screw 704 to rotate within the lifting groove 702. The lead screw 704 drives the lead screw nut 705 on its outer surface to move axially along the lead screw 704. The lead screw nut 705 drives the mounting plate 706 to rise and fall synchronously. The mounting plate 706 then drives the springback compensation assembly 8 to adjust its height, thereby achieving a smooth lifting effect through lead screw transmission. This greatly improves the accuracy and stability of the height adjustment of the lifting assembly 7 and ensures the precise alignment of the springback compensation assembly 8. Furthermore, the springback compensation component 8 includes a slide rod 801 fixedly mounted at the bottom of the mounting plate 706. A slider 803 and a compensation pressure plate 802 are slidably connected to the outer surface of the slide rod 801. A compensation spring 804 is sleeved on the outer surface of the slide rod 801 between the slider 803 and the compensation pressure plate 802. After the sheet metal part is bent, the compensation spring 804 releases its elastic potential energy, pushing the compensation pressure plate 802 to move along the slide rod 801 toward the bent part of the sheet metal part. At the same time, the slider 803 remains relatively stable on the slide rod 801, providing support for the compensation spring 804. This allows the compensation pressure plate 802 to continuously apply pressure to the bent part, thereby achieving the function of springback compensation through spring force. This greatly improves the timeliness of springback compensation and the stability of pressure, effectively offsetting the springback deviation of the sheet metal part. Furthermore, the elastic adjustment component 9 includes a fixed cylinder 901 fixedly mounted on the top of the mounting plate 706. A turntable 902 is rotatably mounted on the top of the fixed cylinder 901. An external threaded rod 903 is fixedly connected to the bottom of the turntable 902. An internal threaded sleeve 904 is slidably connected to the bottom of the external threaded rod 903 through a limiting mechanism. The bottom of the internal threaded sleeve 904 extends to the bottom of the mounting plate 706 and is fixedly connected to the slider 803. When adjusting the elastic compensation amount, the operator rotates the turntable 902, causing the external threaded rod 903 to rotate inside the fixed cylinder 901. The external threaded rod 903 drives the internal threaded sleeve 904 to move axially. The internal threaded sleeve 904 causes the slider 803 to slide along the slide bar 801, changing the compression amount of the compensation spring 804. This achieves the effect of adjusting the spring compression amount through threaded transmission, thereby greatly improving the accuracy and convenience of elastic compensation amount adjustment and adapting to the rebound characteristics of different sheet metal parts. Furthermore, the limiting mechanism includes limiting grooves 905 formed on both sides of the inner wall of the fixed cylinder 901. A limiting plate 906 is slidably connected inside the limiting grooves 905, and the other side of the limiting plate 906 is fixedly connected to the internal threaded sleeve 904. During the operation of the elastic adjustment component 9, when the internal threaded sleeve 904 moves, it drives the limiting plate 906 to slide along the limiting grooves 905. The limiting grooves 905 restrict the rotation of the limiting plate 906, thereby preventing the internal threaded sleeve 904 from rotating synchronously with the external threaded rod 903, ensuring that the internal threaded sleeve 904 only moves axially, thus achieving the function of limiting the rotation direction of the internal threaded sleeve 904, thereby greatly improving the transmission stability and adjustment accuracy of the elastic adjustment component 9, and avoiding jamming during the adjustment process. Furthermore, a baffle is fixedly connected to the bottom of the slide bar 801 to prevent the compensation plate 802 from detaching. When the rebound compensation assembly 8 is working, the compensation plate 802 moves along the slide bar 801. When the compensation plate 802 moves to the bottom of the slide bar 801, the baffle blocks the compensation plate 802 from moving further downward, thus preventing the compensation plate 802 from detaching from the slide bar 801. This achieves the function of preventing the compensation plate 802 from detaching from the slide bar 801, thereby greatly improving the reliability of the rebound compensation assembly 8 and avoiding device failure due to component detachment. Furthermore, a silicone buffer layer is fixedly connected to the bottom of the side of the compensating pressure plate 802 away from the slide bar 801; when the compensating pressure plate 802 applies pressure to the bending part of the sheet metal part, the silicone buffer layer directly contacts the surface of the sheet metal part, relieving the rigid collision between the compensating pressure plate 802 and the sheet metal part, reducing friction and compression on the surface of the sheet metal part, thereby achieving the function of protecting the surface of the sheet metal part, and thus greatly improving the appearance quality of the sheet metal part and avoiding defects such as scratches and indentations. Furthermore, an anti-slip pad is fixedly connected to the outer surface of the turntable 902, and the outer surface of the anti-slip pad has anti-slip texture. When the operator rotates the turntable 902 to adjust the elastic compensation amount, the hand comes into contact with the anti-slip pad on the outer surface of the turntable 902. The anti-slip texture increases the friction between the hand and the anti-slip pad, preventing the hand from slipping during rotation. This increases the friction between the hand and the turntable 902, thereby greatly improving the stability and convenience of the operator when adjusting the turntable 902 and avoiding the impact of slippage on adjustment efficiency.
[0020] Working Principle: In manufacturing fields where high precision bending of sheet metal parts is required, such as automotive body frames and precision housings for electronic devices, this precision sheet metal bending springback compensation positioning device can achieve precise bending and springback control of sheet metal parts. Its specific working principle is as follows: First, the device is fixed to the ground by the base plate 1 to form a stable foundation. The support plate 2 is installed on the top of the base plate 1, and the top plate 3 is further installed on the top of the support plate 2. The three together form a stable working frame, providing reliable support for all subsequent processing steps and effectively avoiding the impact of frame shaking on accuracy during processing. Next, the sheet metal part to be processed is placed in the working area of the device, and then the first motor 602 is started, which drives the rotating shaft 604 to rotate. This causes the rotating shaft 604 to drive the drive gear 605 to rotate. Since the drive gear 605 meshes with the sliding tooth plates 606 on the upper and lower sides at the same time, it can simultaneously drive the two sets of sliding tooth plates 606 to move relative to each other along the inside of the adjusting plate 601. This causes the sliding tooth plates 606 to drive the clamping plate 701 to move synchronously along the adjusting groove 603 on the top of the adjusting plate 601 through the connecting plate 607. Finally, the sheet metal part can be quickly and firmly clamped. The synchronous movement of the clamping plate 701 can ensure that the sheet metal part is subjected to uniform force, completely preventing the sheet metal part from shifting during subsequent bending, and providing a basic guarantee for bending accuracy. Subsequently, based on the actual thickness of the sheet metal part to be processed and the preset bending requirements, the second motor 703 is started, which drives the lead screw 704 to rotate. This causes the lead screw 704 to drive the lead screw nut 705 on its outer surface to move along the axial direction of the lead screw 704. In turn, the lead screw nut 705 drives the mounting plate 706 fixed thereto to rise and fall synchronously. When the mounting plate 706 rises and falls, it will drive the springback compensation component 8 at the bottom to adjust its height until the springback compensation component 8 is precisely aligned with the bending area of the sheet metal part. This avoids the failure of springback control due to the deviation of the compensation position and greatly improves the pertinence of springback compensation. Subsequently, the bending assembly is activated to bend the sheet metal part: the hydraulic cylinder 4 at the top of the top plate 3 outputs power, pushing the bending die 5, which extends to the bottom of the top plate 3, to move downwards, and performing a pre-set angle bending process on the sheet metal part that has been clamped and positioned. Since the clamping assembly 6 has previously achieved stable positioning of the sheet metal part, the sheet metal part remains stable and without displacement during the bending process, ensuring that the initial bending angle meets the processing standards, and at this time the compensation spring 804 is in a compressed state.After the sheet metal part is bent, the compensation spring 804 located between the slider 803 and the compensation pressure plate 802 releases its elastic potential energy, pushing the compensation pressure plate 802 to apply a preset pressure to the bent part of the sheet metal part. This pressure can be directly applied to the bent part of the sheet metal part, effectively offsetting the springback angle deviation caused by the elastic properties of the sheet metal part itself, and significantly improving the final angle accuracy of the sheet metal part after bending. At the same time, the silicone buffer layer at the bottom of the side of the compensation pressure plate 802 away from the slide bar 801 can prevent the pressure plate from directly and rigidly contacting the surface of the sheet metal part, preventing scratches on the surface of the sheet metal part and ensuring its appearance quality. The baffle at the bottom of the slide bar 801 can limit the movement range of the compensation pressure plate 802, preventing it from detaching from the slide bar 801 and ensuring the stable operation of the springback compensation component 8. Furthermore, for sheet metal parts of different materials or thicknesses, the springback compensation amount can be adjusted through the elastic adjustment component 9. During adjustment, the operator first rotates the turntable 902, which drives the bottom external thread rod 903 to rotate. During the rotation of the external thread rod 903, the limiting mechanism formed by the limiting groove 905 on the inner wall of the fixed cylinder 901 and the limiting plate 906 can prevent the internal thread sleeve 904 from rotating synchronously with the external thread rod 903, so that the internal thread sleeve 904 only moves up and down along the axial direction. The internal thread sleeve 904 drives the slider 803 fixed to it to slide along the slide rod 801, thereby changing the compression of the compensation spring 804, realizing the precise adjustment of the elastic compensation amount applied by the springback compensation component 8, so that the device can be adapted to the processing of sheet metal parts of various specifications and materials, greatly improving the versatility and applicability of the device.
