AI Technical Summary
Existing technologies cannot effectively bend specially designed pins, especially in the manufacturing process of electronic components with tight spatial structures, where standard tooling cannot achieve uniform bending of pins.
The device employs a coaxial double-arm bending mechanism for the insert. The first and second rotating arms drive the bending die to rotate, achieving uniform bending of the insert. The second rotating cylinder and the first rotating arm push the bending die to ensure that the insert is subjected to uniform force on both sides, achieving high consistency and protecting the product from defects.
This achieves uniform bending of the pins, improves operational convenience, ensures bending consistency and product quality, and avoids the occurrence of defects.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of bending mechanism, and in particular relates to a double-arm bending mechanism with a pin coaxial. Background Technology
[0002] Magnetizing current refers to a current that produces a magnetic effect in a substance. When a substance is subjected to a magnetic field, electrons inside atoms or molecules move, thereby generating a loop current, which further forms a magnetic field. This current is called magnetizing current. In the production of sockets for electronic components, a coaxial double-arm bending mechanism for pins may be used. A coaxial double-arm bending mechanism for pins is a device used to bend pins. It is commonly used in the manufacturing and assembly of electronic components. However, due to the special dimensions and compact spatial structure of the pins, it is impossible to bend the pins using standard tooling. Therefore, we propose a coaxial double-arm bending mechanism for pins. Utility Model Content
[0003] This utility model provides a coaxial double-arm bending mechanism for inserts. After the first and second rotating arms drive the bending die to rotate, the first and second rotating arms drive the bending die to bend the insert, improving the convenience of bending the insert for the operator.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a coaxial double-arm bending mechanism for inserts, comprising a base plate, wherein upper and lower frame positioning plates are mounted in the middle of the base plate, and curved foot cylinder mounting plates are symmetrically arranged on both sides of the upper and lower frame positioning plates and fixed to the sides of the base plate. The two sets of curved foot cylinder mounting plates are movably connected to curved foot connecting pieces on opposite sides. Upper and lower cylinder mounting plates are mounted at the top of the upper and lower frame positioning plates, and mounting connecting pieces are movably connected in the middle of the upper and lower cylinder mounting plates. A second slider mounting plate is attached to the surface of the mounting connecting piece, and a second slider is mounted on the surface of the second slider mounting plate. The second slider is slidably connected to a first curved foot slider mounting plate, and the first curved foot slider mounting plate is mounted on the frame positioning plate. On the lower upright plate, the end of the bent foot connector is attached to a first bent foot slider mounting plate, and a first slider is mounted on the side of the first bent foot slider mounting plate near the surface of the base plate. The first slider is slidably connected to another slide rail mounted on the base plate. A square skeleton positioning component is mounted on the surface of the second slider mounting plate, and skeleton pin positioning molds are mounted on both sides of the square skeleton positioning component through skeleton pins. A first cylinder mounting plate and a second cylinder mounting plate mounted on the base plate are attached to the upper and lower upright plates of the skeleton positioning plate, respectively. A second rotary cylinder is mounted on the surface of both the first cylinder mounting plate and the second cylinder mounting plate, and a first rotating arm and a second rotating arm are mounted on the output end of the second rotary cylinder, respectively. A bent foot mold is fixed at the end of both the first rotating arm and the second rotating arm.
[0005] Furthermore, each of the curved foot cylinder mounting plates is equipped with a movable cylinder. One end of each movable cylinder is equipped with left and right cylinder limit bolts, and the other end of each movable cylinder is equipped with a curved foot connector via the left and right cylinder limit bolts.
[0006] Furthermore, upper and lower cylinders are mounted on the surface of the upper and lower cylinder mounting plate, upper and lower cylinder limit bolts are mounted on the surface of the upper and lower cylinders, and mounting connectors are mounted on the ends of the upper and lower cylinders through floating joints.
[0007] The beneficial effects of this utility model are:
[0008] This coaxial double-arm bending mechanism for inserts is equipped with a second rotary cylinder, a second rotating arm, a first rotating arm, and a bending die. The second rotary cylinder drives the second and first rotating arms to rotate, which in turn pushes the bending die, causing the bending die to bend the insert. This ensures that the insert is subjected to uniform force on both sides, resulting in high bending consistency and achieving standard dimensions. It also protects the product from defects during bending. Attached Figure Description
