Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, and more specifically, to a rotary clamping device for profile processing. Background Technology

[0002] As a key piece of equipment in the bending process of metal profiles, the profile bending machine plays an irreplaceable role in high-end manufacturing fields such as aerospace, automobile manufacturing, and rail transportation. By applying axial tension and bending moment to the profile, it enables the profile to bend precisely under tension, meeting the forming requirements of complex components. It is a core piece of equipment for ensuring the accuracy and quality of profile processing.

[0003] However, when performing small-radius bending operations on profile bending machines, the bending location of the profile is simultaneously subjected to axial and circumferential tensile forces, causing a sharp reduction in the profile wall thickness. Existing bending machines lack any protective structures at the bending location. This lack of protection makes the excessively thinned outer arc area prone to localized deformation or wrinkling defects under tensile force. This not only prevents the processed profile from meeting assembly and usage requirements but also severely impacts the forming accuracy, mechanical properties, and service life of the processed parts. Especially in fields with extremely high safety requirements, such as aerospace and automotive, this hazard could lead to serious safety consequences. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies in the prior art and provide a rotary clamping device for profile processing. When the profile bending machine performs small-radius bending on the profile, the rotary clamping device can protect the profile to prevent the profile cross-section from deforming or to prevent the profile from wrinkling, thereby achieving high-precision and high-reliability forming of small-radius bending of the profile.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a rotary clamping device for profile processing, characterized in that: the rotary clamping device is disposed on a work platform, the work platform including a platform frame and a mold core disposed on the platform frame; the rotary clamping device includes a rotating component, a clamping component for clamping the profile to the mold core, and a rotary driving component for driving the rotating component to rotate; the clamping component is disposed on the rotating component, and its clamping surface faces the mold core; the rotating component is rotatably disposed on the platform frame, and the rotary driving component is connected to the rotating component.

[0006] When the clamping assembly presses the profile against the mold core, the rotary drive component drives the rotary assembly to rotate synchronously with the bending of the profile, so that the clamping assembly always fits against the supporting profile.

[0007] In the above solution, the rotary clamping device of this utility model rotates synchronously with the bending of the profile, ensuring that the clamping component remains in contact with and supports the profile until the small-radius bending of the profile is completed. Since the profile experiences significant cross-sectional shrinkage and deformation during small-radius bending, the rotary clamping device needs to protect the profile throughout this bending process, preventing cross-sectional deformation and wrinkling. The rotary clamping device matches the outer arc shape of the profile and moves synchronously with the bending point, supporting the profile and preventing shrinkage, deformation, or wrinkling.

[0008] The rotating assembly includes a rotating base module and a rotating clamping seat; the rotating base module is connected to the mold core, and the rotating clamping seat is rotatably connected to the rotating base module; the clamping assembly is disposed on the rotating clamping seat, and the rotating drive component is connected to the rotating clamping seat to drive the rotating clamping seat and the clamping assembly to rotate.

[0009] The rotating base module includes a rotating base, a fixed shaft, and a rotating sleeve; the rotating base is connected to the mold core through the fixed shaft, and the rotating clamping seat is connected to the fixed shaft through the rotating sleeve.

[0010] The clamping assembly includes a clamping drive component, a guide slider, and a clamping plate. The clamping plate is disposed on the guide slider, with its clamping surface facing the mold core. The guide slider is slidably connected to the rotating component and connected to the clamping drive component. The clamping drive component drives the clamping plate on the guide slider to clamp the profile.

[0011] The fastening plate is a fastening adhesive plate. This design effectively protects the profile and prevents it from being scratched or worn during bending processes.

[0012] The rotary clamping device also includes a clamping mechanism for clamping and positioning the profile; the clamping mechanism is mounted on the mold core. Before bending the profile, the clamping mechanism can clamp and position the profile on the mold core, and then the profile can be bent to a small radius.

[0013] The clamping mechanism includes a clamping mounting base, a clamping drive component, a rotating arm module, and a clamping plate; the clamping mounting base is disposed on the mold core; the clamping drive component is hinged to the clamping mounting base; the rotating arm module is hinged to the clamping drive component; the clamping plate is disposed on one end of the rotating arm module, and the other end of the rotating arm module is hinged to the clamping mounting base; during operation, the clamping drive component drives the rotating arm module to rotate, causing the clamping plate to clamp and position the profile to the outside of the mold core.

[0014] The rotating arm module includes a rotating arm and a hinge seat; the hinge seat is connected to the rotating arm and hinged to the clamping drive component; the clamping plate is disposed on one end of the rotating arm, and the other end of the rotating arm is hinged to the clamping mounting seat.

[0015] The clamping plate is a clamping rubber plate. This design effectively protects the profile and prevents it from being scratched or worn during bending.

[0016] The rotary clamping device of this utility model is used as follows: After the first arc bending is performed by the bending machine, the clamping drive component of the clamping mechanism drives the rotating arm to rotate, so that the clamping plate clamps and positions the profile to the outside of the mold core. After positioning, the close-fitting drive component drives the close-fitting rubber plate on the guide slider to press the profile to the mold core. The bending machine performs the second arc (small radius) bending. The rotary drive component drives the rotary clamping seat and the close-fitting rubber plate to rotate, so that the close-fitting rubber plate of the rotary clamping device keeps in contact with and supports the profile until the small radius bending of the profile is completed, and finally the bending and forming of the profile is achieved.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects: When the profile bending machine performs small radius bending on the profile, the rotary pressing device of the present invention can protect the profile to prevent the profile cross-section from deforming or to prevent the profile from wrinkling, thereby achieving high precision and high reliability forming of small radius bending of the profile.

The rotating assembly is rotatably mounted on the platform frame 5, and the rotary drive component is connected to the rotating assembly. When the clamping assembly clamps the profile 2 against the mold core 1, the rotary drive component 4.6 drives the rotating assembly to rotate synchronously with the bending of the profile 2, ensuring that the clamping assembly remains in contact with and supports the profile 2.

[0024] Specifically, the rotating assembly includes a rotating base 4.1, a rotating clamping seat 4.2, a fixed shaft, and a rotating sleeve.

The pressing drive component 4.3 drives the pressing adhesive plate 4.5 on the guide slider 4.4 to press the profile 2.

[0025] The rotary drive component 4.6 is connected to the rotary clamping seat 4.2, enabling the rotary clamping seat 4.6 and the clamping assembly's adhesive plate 4.5 to rotate.

[0026] The rotary clamping device 4 of this utility model also includes a clamping mechanism 6 for clamping and positioning the profile 2, which is disposed on the mold core 1. Before bending the profile, the clamping mechanism 6 can clamp and position the profile 2 on the mold core 1, and then the profile 2 can be bent to a small radius.

[0027] Specifically, the clamping mechanism 6 includes a clamping mounting base 6.1, a clamping drive component 6.2, a hinge shaft seat 6.3, a rotating arm 6.4, and a clamping rubber plate 6.5.

The hinge shaft seat 6.3 is connected to the rotating arm 6.4 and hinged to the clamping drive component 6.2. The clamping rubber plate 6.5 is mounted on one end of the rotating arm 6.4, and the other end of the rotating arm 6.4 is hinged to the clamping mounting base 6.1. During operation, the clamping drive component 6.2 drives the rotating arm 6.4 to rotate, causing the clamping rubber plate 6.5 to clamp and position the profile 2 to the outside of the mold core 1.

[0028] The rotary pressing device of this utility model is used as follows: After the first arc bending is performed by the bending machine 3, the pressing drive component 6.2 of the pressing mechanism 6 drives the rotating arm 6.4 to rotate, so that the pressing rubber plate 6.5 presses and positions the profile 2 to the outside of the mold core 1. After positioning, the close-fitting drive component 4.3 drives the close-fitting rubber plate 4.5 on the guide slider 4.4 to press the profile 2 to the mold core 1. The bending machine 3 performs the second arc (small radius) bending.
