Description
Technical Field
[0001] This utility model relates to the field of machining technology, specifically to a synchronous floating mechanism for a 180-degree reverse-folding part. Background Technology
[0002] In precision stamping and bending processes, traditional mold designs present numerous problems for machining 180-degree inverted parts, affecting machining accuracy and production efficiency. In existing technologies, the structure of the inverted part and the material feeding device are often out of sync, leading to unstable positioning during feeding and impacting part accuracy and consistency. Because the material strip is easily affected by external forces during transport, especially during inverted forming, if the material feeding mechanism cannot maintain good coordination with the forming component, it may cause part misalignment, deformation, or even scrap.
[0003] Furthermore, due to the limitations of traditional stamping die structures, scratches or damage may occur on the surface of parts during processing due to friction, extrusion, and other factors, affecting the product's appearance quality. For certain parts with high requirements for surface finish, such as metal casings for electronic products and precision mechanical parts, such surface defects can seriously affect product performance and market competitiveness. Traditional reverse-folding processing methods often rely on complex die structures and manual adjustments to synchronize material flow, which not only increases production costs but also reduces production efficiency, making it difficult to meet the demands of modern manufacturing for efficient and precise machining. Utility Model Content

The implementation methods of this utility model will now be described based on its overall structure.
[0033] This utility model discloses a synchronous floating mechanism for a 180-degree inverted bending part. The unprocessed part 11 undergoes three inverted bending processes to achieve the final 180-degree inverted bending: the first bend is 90 degrees, the second bend is a further 45-degree bend, and the third completes the 180-degree inverted bending. The floating mechanism must maintain the position of the part 11 throughout these three actions to prevent springback and deformation. This utility model demonstrates the floating mechanism for the third bending step.
[0034] In existing floating mechanisms, the floating plate 3 and the molding component move independently, which may cause the material placed on the molding component to shift, resulting in uneven floating force, which in turn leads to unstable molding and increases the probability of material deformation or even scrap.
[0035] like Figures 1 to 6 As shown, this utility model discloses a synchronous floating mechanism for 180-degree reverse folding of parts, used to reverse fold and form the parts 11 to be processed attached to the material strip 1, including:
[0036] Template 2 below;
[0037] The floating plate 3 is movably installed on the lower template 2 and can move up and down;
[0038] The molding component 4 is movably mounted on the lower template 2 relative to the floating material plate 3, and the molding component 4 is capable of moving toward or away from the floating material plate 3;
[0039] The floating plate 3 also includes a conveying section 31 for placing the material strip 1, and the conveying section 31 is located at one end of the floating plate 3 near the forming component 4;
[0040] The feeding section 31 is equipped with a first forming section 32, and the forming assembly 4 is equipped with a second forming section 41 that matches the first forming section 32. The second forming section 41 is located below the first forming section 32, thereby folding the part 11 in reverse to form it.
[0041] With the above structure, the floating plate 3 moves up and down relative to the lower template 2. A conveying section 31 is provided at the end of the floating plate 3 facing the forming component 4. The material strip 1 is placed on the conveying section 31. Under the action of the upper mold (not shown), the floating plate 3 moves downward. At this time, the forming component 4 moves towards the floating plate 3. The first forming part 32 and the second forming part 41 press the part 11 located on the conveying section 31, folding it back into shape. The upper mold moves upward, and the floating plate 3 moves upward relative to the lower template 2, simultaneously driving the material strip 1 upward as well. The floating plate 3 and the first forming part 32 move up and down synchronously, serving both as a forming tool and a floating tool. After one part 11 is folded back, the material strip 1 is moved, so that the next part 11 to be formed is located on the first forming part 32 of the conveying section 31 and then folded back into shape by the forming component 4.
[0042] Specifically, a first forming part 32 is installed on the feeding section 31, and a second forming part 41 is installed on the forming assembly 4 opposite to the first forming part 32. The floating plate 3 moves downwards, and after the first forming part 32 and the second forming part 41 are at the same horizontal height, the forming assembly 4 drives the second forming part 41 to move towards the first forming part 32, performing a second bend on the zero-level part that has completed the first two bending steps, completing a 180-degree reverse bending forming. At least one part 11 to be formed is placed on the first forming part 32 at a time, and the second forming part 41 is located below the first forming part 32. During forming, the first forming part 32 and the second forming part 41 overlap vertically. When forming the part 11, there is a gap between the first forming part 32 and the second forming part 41 that can accommodate the thickness of the part 11 to prevent damage to the surface of the part 11. After forming is completed, the forming assembly 4 drives the second forming part 41 to move away from the feeding section 31, and the floating plate 3 and the first forming part 32 move upwards synchronously, completing the floating process. After a part 11 is folded back and formed, the next part 11 to be formed is placed on the first forming part 32, and the folding and forming process is repeated.
[0043] In this embodiment, the float plate 3 is connected to the lower template 2 via a nitrogen spring 33, allowing it to move up and down in a direction perpendicular to the lower template 2. The nitrogen spring 33, as an elastic support element, can be compressed under force and automatically reset after the external force is released, thus giving the float plate 3 buffering and rebound capabilities, thereby improving the stability of the float mechanism. Furthermore, the float plate 3 can be flexibly adjusted according to the pressure changes of the nitrogen spring 33, enabling it to adapt to material strips 1 of different thicknesses and improving the versatility of the equipment.
[0044] In this embodiment, the feeding unit 31 further includes a guide groove 311 and a guide ruler 312. The guide groove 311 provides a defined movement trajectory for the material belt 1, ensuring that it is conveyed along a fixed path. The guide ruler 312 is adjacent to the guide groove 311 and is mounted on the floating plate 3. The projection of the guide ruler 312 on the horizontal plane can cover the guide groove 311, further assisting in the precise positioning and guidance of the material belt 1. The guide groove 311 provides a fixed movement channel for the material belt 1, enabling it to maintain stable linear movement and avoiding the impact of deviation or twisting on the processing effect. The guide ruler 312 can enhance the constraint force of the material belt 1, ensuring that it is always in the correct position during bending, reducing dimensional errors or scrap caused by inaccurate feeding.
[0045] In this embodiment, the floating plate 3 is also provided with a limiting part 34 for accommodating the folded part 11. The limiting part 34 is adjacent to the conveying part 31 and faces the side of the conveying part 31 in the direction of material conveyor belt 1 movement. The limiting part 34 is used to accommodate the completed 180°...
[0046] After being folded and formed, the part 11 is effectively positioned to prevent it from shifting or bouncing due to inertia or impact during subsequent processing. The limiting part 34 can accurately match the shape and size of the folded part 11, keeping it stably in the predetermined position, thereby positioning the entire material strip 1, improving the processing efficiency of the part 11, and reducing processing errors.
[0047] In this embodiment, a guide post 35 is also connected between the float plate 3 and the lower template 2, so that the float plate 3 can remain stable during up and down movement and move along the trajectory of the guide post 35 along its length. The guide post 35 enables the float plate 3 and the lower template 2 to form a sliding fit relationship, thereby ensuring that the float plate 3 will not tilt or deviate when subjected to force.
[0048] In this embodiment, the structure has a movable groove 5 on the lower template 2 for the forming component 4 to move back and forth, allowing the forming component 4 to move along a fixed trajectory. The forming component 4 includes a cylinder 42 installed in the movable groove 5, a pressure block 43 fixedly connected to the movable end of the cylinder 42, and a second forming part 41 installed on the side of the pressure block 43 facing the feeding part 31. Driven by the cylinder 42, the pressure block 43 can move back and forth in the movable groove 5, allowing the second forming part 41 to cooperate with the first forming part 32 to complete the 180-degree reverse bending forming of the part 11. The cylinder 42 driving method in the movable groove 5 is more efficient and controllable than traditional mechanical driving, making the forming action more stable, reducing the damage to the part 11 caused by impact force, and improving the bending quality. In addition, the fixed connection between the pressure block 43 and the cylinder 42 ensures that the forming component is subjected to uniform force, reducing the deformation of the part 11 caused by uneven force, improving the forming consistency, and making the production efficiency higher.
[0049] In this embodiment, the end of the second forming part 41 is provided with a rounded corner structure, which can improve the bending quality, reduce damage to the part 11, and extend the service life of the mold. The rounded corner structure can effectively reduce stress concentration during the bending process, avoid breakage or damage to the part 11 due to sharp corners or poor transition, and improve the bending quality and consistency of the part 11. When the rounded corner structure contacts the part 11 on the material strip 1, it can reduce friction and scratching, reduce the risk of surface damage to the part 11, and ensure the surface finish of the part 11 after bending. In addition, the rounded corner can also reduce the wear of the second forming part 41 itself, avoid damage to the second forming part 41 due to long-term contact between the sharp edge and the part 11, increase its service life, and reduce maintenance costs.
[0050] In this embodiment, the forming component 4 also includes a guide block 44. The bottom sides of the pressure block 43 have outwardly protruding protrusions 431. The guide block 44 is installed on both sides of the movable groove 5 and located above the protrusions 431, forming a limiting structure together with the protrusions 431. This improves the stability of the forming component 4's movement and enhances its bending accuracy. The limiting structure formed by the guide block 44 and the protrusions 431 effectively constrains the movement trajectory of the pressure block 43, ensuring that it does not deviate or wobble during forward and backward movement, making the forming action more accurate, thereby improving bending accuracy and the consistency of the parts 11. Simultaneously, the limiting structure also prevents the pressure block 43 from jamming or misaligning during operation, making the forming process smoother, improving the efficiency of automated production, and thus enhancing processing accuracy, equipment lifespan, and production efficiency.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
