Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a traceless bending device. Background Art

[0002] As industrial technology continues to rapidly advance, manufacturing processes in various fields are constantly reaching new heights. Against this backdrop, manufacturers are increasingly demanding the appearance of stamped parts. Precision and integrity are directly related to the stability and reliability of equipment operation. During the bending process, bending scratches are not allowed.

[0003] Because once there is a bending scratch, the appearance of the parts will lose its smooth and flat visual effect, and defects such as scratches and rubbing marks will appear, which will damage the overall appearance of the product and reduce market competitiveness. Functional parts may cause stress concentration and dimensional deviation in the scratched area, which will bury the hidden danger of failure in subsequent use and affect the normal operation of the equipment. Therefore, in order to meet customers' high-quality requirements for stamping parts, it is urgent to find effective methods in the actual operation process of stamping and bending to ensure the processing quality of stamping parts and meet the current market and production needs. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model proposes a traceless bending device which avoids friction between the punch and the product during the bending process and eliminates the problem of bending scratches.

[0005] In order to solve the above technical problems, the technical solution proposed by the present invention is: a markless bending device, comprising:

[0006] The bottom plate is the bottom support of the entire device; it avoids shaking and displacement caused by unstable foundation during bending operation, which can greatly reduce the risk of workpiece being scratched by device shaking, lays a solid foundation for precise and seamless bending, and ensures overall stable operation.

[0007] The floating plate is horizontally arranged above the base plate, and four guide pillars are symmetrically provided on the upper surface of the base plate, and the guide pillars are plugged into the holes under the floating plate; springs are sleeved on the outer sides of the guide pillars; support blocks are fixed on both sides of the upper surface of the base plate, and holes are provided on the floating plate for the support blocks to pass through; the floating plate is precisely guided by the guide pillars, so that it can only be stably lifted and lowered in a predetermined direction, and cooperates with the sleeved springs to effectively buffer the impact force during bending, and avoid rigid impact from scratching the workpiece.

[0008] The fixed block is fixed in the middle of the floating plate and has empty slots on both sides. A pendulum block is arranged in the empty slot to rotate through a fixed pin. The pendulum block and the support block are connected by a tension spring to ensure that the overall force is uniform and symmetrical.

[0009] The workpiece is placed on two pendulum blocks.

[0010] Furthermore, the guide posts are arranged at the four corners of the bottom plate, effectively resisting multi-directional forces, reducing shaking and deviation, minimizing the risk of workpiece scratches caused by abnormal floating plates, and ensuring reliable and seamless bending.

[0011] Furthermore, two tension springs are attached to the same position on the pendulum block. This double tension ensures greater stability and reliability. Compared to a single tension spring, it can more firmly position the pendulum block during complex bending processes.

[0012] Furthermore, the support block is provided with two knobs for the tension spring to connect to. The double knobs provide redundancy, and even if one of them fails, the tension spring connection can still be maintained, ensuring stable operation of the device and continuous support for seamless bending.

[0013] Compared with the existing technology, the advantages of the present invention are: this markless bending device has a unique advantage in avoiding the problem of bending scratches. First, the structural design is exquisite. The bottom plate serves as a stable foundation. It is equipped with four corner guide columns and springs. When the punch is pressed and the floating plate is raised and lowered, it can effectively buffer the rigid impact, resolve the excess vertical force, prevent the vibration of the device from being transmitted to the product, and avoid scratches caused by the punch and the product due to shaking collision. Second, the pendulum block works in coordination with the tension spring and the support block. The double configuration of the tension spring strengthens the tension stability. The double convex button ensures a reliable connection. The pendulum block fits tightly to the product and flexibly swings to adjust its posture as the bending process progresses. It accurately disperses the bending force, stabilizes the product from the side, and eliminates scratches caused by uneven force and local extrusion. Furthermore, the workpiece is steadily held and positioned by the pendulum block throughout the entire process. When the punch is pressed down, the pendulum block adaptively deforms and cleverly guides the product to bend, so that there is no direct hard friction or scratches between the product and the punch, ensuring a markless surface and comprehensively guaranteeing the product's appearance and precision.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Combined with attachment Figure 1 To the attached Figure 5 , a markless bending device, comprising:

[0022] The bottom plate is the bottom support of the entire device; it avoids shaking and displacement caused by unstable foundation during bending operation, which can greatly reduce the risk of workpiece being scratched by device shaking, lays a solid foundation for precise and seamless bending, and ensures overall stable operation.

[0023] The floating plate is horizontally arranged above the base plate, and four guide pillars are symmetrically provided on the upper surface of the base plate, and the guide pillars are plugged into the holes under the floating plate; springs are sleeved on the outer sides of the guide pillars; support blocks are fixed on both sides of the upper surface of the base plate, and holes are provided on the floating plate for the support blocks to pass through; the floating plate is precisely guided by the guide pillars, so that it can only be stably lifted and lowered in a predetermined direction, and cooperates with the sleeved springs to effectively buffer the impact force during bending, and avoid rigid impact from scratching the workpiece.

[0024] The fixed block is fixed in the middle of the floating plate and has empty slots on both sides. A pendulum block is arranged in the empty slot to rotate through a fixed pin. The pendulum block and the support block are connected by a tension spring to ensure that the overall force is uniform and symmetrical.

[0025] The workpiece is placed on two pendulum blocks.

[0026] The guide pillars are arranged at the four corners above the base plate. They can effectively resist multi-directional forces, reduce shaking and offset, minimize the hidden dangers of workpiece scratches caused by abnormal floating plates, and ensure reliable implementation of seamless bending. There are two tension springs on the same side, and the two tension springs are connected to the same position on the pendulum block. Double tension ensures greater stability and reliability. Compared with a single tension spring, it can more firmly position the pendulum block during complex bending processes. Two convex buttons for connecting the tension springs are provided on the support block. The double convex buttons have redundancy. Even if one of them has an abnormality, the tension spring connection can still be maintained, ensuring stable operation of the device and continuously assisting in seamless bending.

[0027] Working principle: Place the markless bending device stably on a stable workbench, check the base plate 1, guide column 3, spring 4, support block 5, tension spring 9 and pendulum block 8 and other components to ensure that all components are intact, firmly connected and operate smoothly.

[0028] Place the workpiece to be bent gently on the two pendulum blocks 8. Under the action of the tension spring 9, the pendulum blocks 8 fit tightly to both sides of the bottom of the workpiece, firmly lift and accurately position it, disperse the gravity of the workpiece, and avoid initial damage.

[0029] When the external bending force is activated, pressure is transmitted to the floating plate 2, which descends steadily along the four corner guide posts 3. Springs 4 on the guide posts 3 cushion the impact. Simultaneously, under the influence of the support block 5, the pendulum block 8 swings upward about the fixed pin. During this swing, the stamped part deforms as the pendulum block 8 moves, ultimately achieving the bending effect.

[0030] After the bending is completed, the punch is withdrawn, the floating plate 2 is reset with the help of the spring 4, and the pendulum block 8 returns to its position under the action of the tension spring 9. Carefully remove the workpiece, check that there is no scratch and the accuracy meets the standard, then you can continue the operation or transfer to the next process.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meaning of the above terms in the present invention can be understood according to specific circumstances.

[0032] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
