Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing equipment, specifically to an aluminum strip bending device for automotive connecting parts. Background Technology

[0002] Current aluminum strip bending devices for automotive connectors primarily function to bend aluminum strips into specific angles or shapes according to the size requirements of the parts. They are widely used in the processing of automotive electrical connections, chassis components, and other parts. Their basic structure typically includes a frame, positioning mechanism, bending actuator, and power system. CNC-driven devices, due to their high degree of automation and stable bending accuracy, have become the mainstream choice for mass production. Manual or simple hydraulic devices, on the other hand, are often used for small-batch, multi-specification flexible processing scenarios due to their low cost and compact structure.

[0003] In existing devices, the positioning components of most devices are fixed structures. When the aluminum busbar specifications change, it is necessary to disassemble and replace the positioning blocks or adjust multiple components. This is not only cumbersome and inefficient, but also prone to bending accuracy deviations due to adjustment errors. Furthermore, some devices lack anti-deformation structures for the aluminum busbar, making it susceptible to warping at both ends during bending due to uneven stress. This requires additional manual correction, increasing processing steps and time costs. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum strip bending device for automotive connecting parts, in order to solve the problems mentioned in the background art. Most devices have fixed positioning components, and when the aluminum strip specifications are changed, it is necessary to disassemble and replace the positioning block or adjust multiple parts. This is not only cumbersome and inefficient, but also prone to bending accuracy deviation due to adjustment errors. In addition, some devices lack aluminum strip anti-deformation structure, and the two ends of the aluminum strip are prone to warping due to uneven force during the bending process, requiring additional manual correction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum strip bending device for automotive connecting parts, including a positioning base, which provides a supporting foundation for the entire device, a worktable is horizontally arranged at the top of the positioning base, and an aluminum strip support platform is engaged at the top of the worktable, the aluminum strip support platform being used to support the aluminum strip to be bent; A lifting column is vertically installed at the top corner of the positioning base, and an upper mold connecting block is connected to the top of the output end of the lifting column. The upper mold connecting block is arranged parallel above the aluminum strip support platform, and a positioning slide is provided on the upper surface of the aluminum strip support platform along the length direction. The positioning slide is slidably connected to the aluminum strip limit frame. The aluminum row limiting frame is fixed to the surface of the aluminum row bearing platform by bolts, and the positioning frame is engaged with the aluminum row limiting frame. The surface of the aluminum row limiting frame is provided with bending grooves. The bottom end of the upper mold connecting block is provided with aluminum row pressure plates at equal intervals, and the aluminum row pressure plates are threadedly connected to the bottom end of the upper mold connecting block by positioning bolts.

[0006] Using the above technical solution, the positioning slide bar, together with the sliding aluminum strip limit frame, can adjust the limit position without disassembling and replacing the positioning block. The positioning frame and bending groove assist in positioning and improve bending accuracy. The U-shaped aluminum strip pressure plate is fixed by the positioning bolt, which can stably press the aluminum strip and prevent local stress concentration.

[0007] Preferably, the positioning base has a cavity inside, and auxiliary hydraulic columns are installed at equal intervals inside the cavity of the positioning base, and infrared distance detectors are symmetrically arranged on opposite sides of the upper end of the positioning base.

[0008] Using the above technical solution, the auxiliary hydraulic column in the positioning base can provide stable support for the aluminum strip support platform, and the symmetrically arranged infrared distance detectors can monitor the position of the upper mold components in real time, avoid the risk of collision or accidental contact in advance, and improve operational safety.

[0009] Preferably, the output end of the auxiliary hydraulic column is connected to the bottom end of the aluminum busbar support platform, and the top surface of the aluminum busbar support platform is flush with the top surface of the workbench.

[0010] By adopting the above technical solution, the auxiliary hydraulic column is directly connected to the aluminum busbar support platform, which can accurately maintain the platform and the worktable at the same level, ensuring that the aluminum busbar is subjected to uniform force when bending and reducing bending deviation caused by the tilt of the support platform.

[0011] Preferably, the aluminum strip limiting frame has side protective strips that are snapped onto both sides, and the side protective strips are designed with an inclined structure.

[0012] Using the above technical solution, the inclined side guard strips on both sides of the aluminum row limit frame can effectively block the splashing of metal debris generated by bending, protect the device components from wear, and prevent debris from scratching the operator.

[0013] Preferably, the aluminum strip pressure plate and the aluminum strip limiting frame are arranged in parallel vertically, and the aluminum strip pressure plate is configured with a U-shaped structure, and a protective plate is snapped onto the surface of the aluminum strip pressure plate.

[0014] By adopting the above technical solution, the aluminum strip pressure plate and the aluminum strip limiting frame are aligned vertically to ensure accurate pressing position. The U-shaped structure and the protective plate work together to not only conform to the shape of the aluminum strip to distribute pressure, but also prevent the surface of the aluminum strip from being crushed and reduce the risk of deformation.

[0015] Preferably, the protective plate has grooves evenly spaced on its surface to protect the aluminum strip and surrounding components during bending.

[0016] By adopting the above technical solution, the grooves on the surface of the protective plate can be adapted to the contour of the aluminum strip, enhancing the fit with the aluminum strip, further balancing the bending pressure, preventing local depressions in the aluminum strip due to uneven surface stress, and protecting the structure of the pressure plate itself.

[0017] Preferably, the infrared distance detector's monitoring end faces the bottom of the upper module connecting block.

[0018] With the above technical solution, the infrared distance detector monitoring end faces the bottom of the upper mold connecting block, which can directly monitor the distance between the upper mold and the aluminum strip, ensuring that protection is quickly triggered in case of abnormality, and avoiding excessive compression of the aluminum strip or damage to components.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the aluminum strip bending device for automotive connecting parts: 1. The aluminum strip limiter can slide along the positioning slide bar set along the length of the aluminum strip support platform to adjust its position without disassembling or replacing the positioning block. The position of the limiter can be fixed by bolts, which greatly simplifies the changeover operation process. At the same time, the positioning frame that is interlocked between the aluminum strip limiters can help limit the bending section of the aluminum strip. It can also achieve pre-positioning with the bending groove on the surface of the limiter, avoiding the error caused by multiple adjustments. This effectively improves the changeover efficiency while ensuring the bending positioning accuracy of aluminum strips of different specifications. 2. The aluminum strip pressure plate at the bottom of the upper mold connecting block has a U-shaped structure and is aligned parallel to the aluminum strip limit frame. It can stably press the aluminum strip and distribute the pressure before bending, avoiding localized stress concentration on the aluminum strip. The protective plate that is snapped onto the surface of the aluminum strip pressure plate adapts to the shape of the aluminum strip through surface grooves, further conforming to the surface of the aluminum strip to maintain force balance. At the same time, the auxiliary hydraulic column in the positioning base cavity is connected to the bottom of the aluminum strip support platform, which can stably support the support platform and keep it flush with the worktable, ensuring that the aluminum strip is subjected to uniform force when bending, effectively preventing warping at both ends of the aluminum strip due to uneven force, eliminating the need for additional manual correction and reducing subsequent processing costs. 3. The infrared distance detectors symmetrically arranged on the upper end of the positioning base face the bottom of the upper mold connecting block, which can monitor the distance between the upper mold component and the aluminum strip in real time. In case of abnormality, the protection mechanism can be triggered in time to avoid the risk of component collision or accidental contact by personnel. The side protective strips of the inclined structure on both sides of the aluminum strip limit frame can block the debris generated during bending and reduce component wear. In addition, the positioning base provides stable support, and the lifting column drives the upper mold connecting block. The overall structure has strong synergy, which not only ensures operational safety but also improves the long-term stability of the device and extends its service life. Attached Figure Description

Infrared distance detectors 14 are symmetrically installed on both sides of the upper end of the positioning base 1, ensuring that their monitoring ends face the bottom end of the upper mold connecting block 10. The aluminum strip limit frame 6 is fixed to the surface of the aluminum strip support platform 3 by bolts, and the positioning frame 7 is engaged between the aluminum strip limit frames 6. The surface of the aluminum strip limit frame 6 is provided with bending grooves.

[0025] Working principle: When using the aluminum strip bending device for automotive connecting parts, the positioning base 1 is used as a support, and the aluminum strip support platform 3 is installed on the worktable 2 at the top.

The positioning frame 7 is engaged between the aluminum strip limit frames 6, and the bending groove on the surface of the aluminum strip limit frame 6 is used for the pre-positioning of the aluminum strip bending to prevent the aluminum strip from shifting horizontally. The lifting column 9 at the top corner of the positioning base 1 is activated, and its output end drives the upper mold connecting block 10 to move down, so that the aluminum strip pressure plate 11 installed at the bottom end of the upper mold connecting block 10 through the positioning bolt 12 is aligned vertically with the aluminum strip limit frame 6, forming a U-shaped structure to press the aluminum strip. The lifting column 9 continues to drive the upper mold connecting block 10 to move down, and the aluminum strip pressure plate 11 cooperates with the bending groove of the aluminum strip limit frame 6 to bend the aluminum strip. If the height needs to be adjusted, the auxiliary hydraulic column 4 in the cavity of the positioning base 1 pushes the aluminum strip support platform 3 to rise and fall, assisting in completing the bending. During bending, the inclined structure side guard strips 8 on both sides of the aluminum strip limit frame 6 block debris; the guard plate 13 that is engaged with the surface of the aluminum strip pressure plate 11 protects the aluminum strip and surrounding components through the groove; the infrared distance detector 14 at the upper end of the positioning base 1 monitors the distance in real time with the monitoring end facing the bottom end of the upper mold connecting block 10, and triggers protection when abnormal. After bending, the lifting column 9 drives the upper mold connecting block 10 and the aluminum strip pressure plate 11 to move up and reset; loosen the bolts of the aluminum strip limit frame 6, move the aluminum strip limit frame 6 and the positioning frame 7 along the positioning slide bar 5, and take out the bent aluminum strip, which increases the overall practicality.
