Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically to an angle adjustment tool for bending and forming copper strips. Background Technology

[0002] In the bending and forming process of copper strip, traditional tooling often suffers from problems such as inconvenient angle adjustment and poor adaptability, making it difficult to quickly adapt to the processing requirements of copper strips of different thicknesses. Existing equipment usually relies on a fixed roller structure, lacking a flexible and adjustable clamping and guiding mechanism, resulting in low bending accuracy and cumbersome operation. In addition, conventional push bending methods are mostly manual or mechanically forced forming, which can easily cause damage to the surface of the copper strip or uneven deformation. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed and easy-to-use angle adjustment tool for bending and forming copper strips, which can effectively solve the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it comprises a tooling plate, support blocks, and support rods, wherein support blocks are fixed at the four corners of the bottom wall of the tooling plate, and support rods are fixed on the upper surface of the tooling plate; it also comprises: Fixed rollers, there are several fixed rollers, and they are equidistantly screwed onto the upper side of the tooling plate through bearings. Each fixed roller is provided with a corresponding movable roller on its rear side. Several movable rollers are equidistantly screwed onto a sliding plate through bearings. The sliding plate is slidably set in a groove on the upper surface of the tooling plate. Two adjusting screws are symmetrically connected to the sliding plate by threads. The adjusting screws are screwed into the tooling plate by bearings. The two adjusting screws are connected by a synchronous pulley transmission assembly. One end of one of the adjusting screws is connected to an adjusting motor that is fixedly connected to the side wall of the tooling plate. A push rod is provided on one side above the tooling plate. The lower side of the push rod is slidably provided on the surface of the tooling plate via an arc-shaped slider. A connecting rod is fixed on the inner wall of the arc-shaped slider. The other end of the connecting rod is screwed to the center of the arc-shaped groove on the tooling plate via a shaft. The shaft is connected to the tooling plate via a torsion spring. A pushing mechanism is provided inside the tooling plate and is connected to the arc-shaped slider; According to the above technical solution, based on the thickness of the copper strip, the adjusting motor is started, which drives the adjusting screw connected to it to rotate. This adjusting screw drives another adjusting screw to rotate through the synchronous wheel transmission assembly. The two adjusting screws drive the movable roller to move through the sliding plate until the front and rear fixed rollers and the movable roller clamp the copper strip, which facilitates the guidance of the copper strip. After the copper strip is moved to the appropriate position, the pushing mechanism pushes the arc-shaped slider. The arc-shaped slider moves in the arc-shaped groove with the shaft at the end of the connecting rod as the axis, thereby pushing the copper strip to achieve the bending effect.

[0005] As a further improvement of this utility model, several fixed rollers are connected by a synchronous wheel transmission assembly, and a drive motor is connected to the bottom of one of the fixed rollers. The drive motor is embedded and fixed in the tooling plate. With the above technical solution, when pushing the copper strip, the drive motor is started, and the drive motor drives the fixed roller connected to it to rotate. The fixed roller drives another fixed roller to rotate through the synchronous gear transmission assembly, thereby facilitating the movement of the copper strip.

[0006] As a further improvement of this utility model, the driving mechanism includes: A drive motor is embedded and fixed in the tooling plate, and a drive disk is fixed on the output shaft of the drive motor. The drive disk is movably disposed in the tooling plate. The movable rod is movably inserted into the push plate, and a toggle plate is fixed at the upper end of the movable rod. The toggle plate is movably disposed in the tooling plate. The fixed rod is fixed to the bottom wall of the arc-shaped slider. The fixed rod is engaged with the actuating plate. One side of the actuating plate abuts against the limit frame. The horizontal plate on the upper side of the limit frame is movably disposed in the arc-shaped groove on the upper surface of the tooling plate. The horizontal plate of the limit frame is engaged with the inner wall of the arc-shaped groove through threads. A stop spring is fixed to the bottom wall of the movable rod, and the lower end of the stop spring is fixed to the inner bottom wall of the push plate. Using the above technical solution, the limiting frame is moved to a suitable position according to the required bending angle and positioned by bolts. Then, the push motor is started, which drives the push disk to rotate. The push disk drives the movable rod and the actuating plate to rotate. When the actuating plate abuts against the fixed rod, the fixed rod drives the arc-shaped slider to move. When the arc-shaped slider moves to the point where the actuating plate abuts against the limiting frame, the inclined surface on the bottom wall of the limiting frame abuts against the actuating plate, causing the actuating plate and the movable rod to move downward and compress the contact spring, thereby releasing the contact with the fixed rod. After releasing, the elastic force of the torsion spring on the shaft at the end of the connecting rod drives the arc-shaped slider to return to its original position, making it easy to bend again next time.

[0007] As a further improvement of this utility model, an annular slide rail is fixed on the lower surface of the push plate, and the annular slide rail is slidably disposed in an annular groove on the bottom wall of the tooling plate; this can increase the stability of the push plate when it rotates.

[0008] As a further improvement of this utility model, a limit ring is sleeved and fixed at the lower end of the movable rod, and the limit ring is slidably arranged in the cylindrical groove in the push plate; The above technical solution can limit the movement of the lever, preventing the lever and the actuating plate from moving out of the push plate.

[0009] As a further improvement of this utility model, a rubber pad is fixed inside the arc-shaped groove, and the bolts on the limiting frame are set to abut against the rubber pad; this can better limit the positioning of the limiting frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The angle adjustment tool for bending and forming copper strip described in this utility model can realize the precise adjustment of the clamping distance of copper strip, adapt to materials of different thicknesses, improve bending accuracy and operational flexibility, and has the advantages of reasonable design and low manufacturing cost.

[0018] Example 1:

[0019] like Figures 1-5 As shown, this embodiment includes a tooling plate 1, support blocks 2, and support rods 3. Support blocks 2 are welded and fixed to the four corners of the bottom wall of the tooling plate 1, and support rods 3 are welded and fixed to the upper surface of the tooling plate 1. It also includes: Fixed rollers 4, several of which are equidistantly screwed onto the upper side of the tooling plate 1 via bearings.

The sliding plate 6 is slidably positioned within a groove on the upper surface of the tooling plate 1. The fixed rollers 4 are connected to each other via a synchronous pulley transmission assembly. A drive motor 13 is connected to the bottom of the right-side fixed roller 4. The drive motor 13 is embedded and fixed within the tooling plate 1. When the copper strip is pushed, the drive motor 13 is activated, causing the connected fixed roller 4 to rotate. This fixed roller 4, through the synchronous pulley transmission assembly, drives the other fixed rollers 4 to rotate, thus facilitating the movement of the copper strip. Adjusting screw 7, there are two adjusting screws 7, which are symmetrically connected to the sliding plate 6 by threads. The adjusting screw 7 is screwed into the tooling plate 1 by bearings. The two adjusting screws 7 are connected by a synchronous wheel transmission assembly. The rear end of the right adjusting screw 7 is connected to an adjusting motor 8 that is fixedly connected to the side wall of the tooling plate 1. Push rod 9 is located on one side above tooling plate 1. The lower side of push rod 9 is slidably disposed on an arc-shaped groove on the upper surface of tooling plate 1 via an arc-shaped slider 10. A connecting rod 11 is welded and fixed on the inner wall of the arc-shaped slider 10. The other end of the connecting rod 11 is screwed to the center of the arc-shaped groove on tooling plate 1 via a shaft. The shaft is connected to tooling plate 1 via a torsion spring. The pushing mechanism 12 is disposed in the tooling plate 1 and is connected to the arc-shaped slider 10.

[0020] Example 2:

[0021] See Figure 1 , Figure 4-5 As shown, based on Embodiment 1, the pushing mechanism 12 includes: A drive motor 12-1 is embedded and fixed inside the tooling plate 1. A drive disk 12-2 is fixed on the output shaft of the drive motor 12-1 and is movably disposed inside the tooling plate 1. An annular slide rail 14 is welded and fixed on the lower surface of the drive disk 12-2 and is slidably disposed in an annular groove on the bottom wall of the tooling plate 1. This can increase the stability of the drive disk 12-2 when it rotates. The movable rod 12-3 is movably inserted into the push plate 12-2. The upper end of the movable rod 12-3 is fixed with a toggle plate 12-4, which is movably disposed within the tooling plate 1. The lower end of the movable rod 12-3 is fitted with and welded with a limit ring 15, which is slidably disposed in a cylindrical groove within the push plate 12-2. This limit ring 15 can limit the movable rod 12-3 and prevent the movable rod 12-3 and the toggle plate 12-4 from moving out of the push plate 12-2. A fixing rod 12-5 is welded and fixed to the bottom wall of the arc-shaped slider 10. The fixing rod 12-5 is engaged with the actuating plate 12-4. One side of the actuating plate 12-4 abuts against the limiting frame 12-6. The horizontal plate on the upper side of the limiting frame 12-6 is movably disposed in the arc-shaped groove on the upper surface of the tooling plate 1, and the horizontal plate of the limiting frame 12-6 is engaged with the inner wall of the arc-shaped groove through threads. A rubber pad 16 is fixed in the arc-shaped groove, and the bolts on the limiting frame 12-6 abut against the rubber pad 16, which can better limit the positioning of the limiting frame 12-6. The contact spring 12-7 is welded and fixed to the bottom wall of the movable rod 12-3, and the lower end of the contact spring 12-7 is welded and fixed to the inner bottom wall of the push plate 12-2.

[0022] When using this invention, the adjusting motor 8 is started according to the thickness of the copper strip. The adjusting motor 8 drives the adjusting screw 7 connected to it to rotate. This adjusting screw 7 drives another adjusting screw 7 to rotate through the synchronous pulley transmission assembly. The two adjusting screws 7 drive the movable roller 5 to move through the sliding plate 6 until the front and rear fixed rollers 4 and the movable roller 5 clamp the copper strip, which facilitates the guidance of the copper strip. After the copper strip is moved to a suitable position, the limiting frame 12-6 is moved to a suitable position according to the required bending angle and positioned by bolts. Then, the push motor 12-1 is started. The push motor 12-1 drives the push plate 12-2 to rotate. The push plate 12-2 drives the movable rod 12-3 and the actuating plate 12-4 to rotate. When the actuating plate 12-4 abuts against the fixed rod 12-5, the fixed rod 12-5 drives the arc-shaped slider 10 to move. The arc-shaped slider 10 moves in the arc-shaped groove with the shaft at the end of the connecting rod 11 as the axis, thereby pushing the copper strip to achieve the bending effect. When the arc-shaped slider 10 moves to the point where the actuating plate 12-4 abuts against the limiting frame 12-6, the inclined surface on the bottom wall of the limiting frame 12-6 abuts against the actuating plate 12-4, causing the actuating plate 12-4 and the movable rod 12-3 to move downward and compress the contact spring 12-7, thereby releasing the contact with the fixed rod 12-5. After releasing, the arc-shaped slider 10 is reset by the elastic force of the torsion spring on the shaft at the end of the connecting rod 11, making it easy to bend again next time.

[0023] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. The synchronous lead screw mechanism driven by the motor can precisely adjust the spacing of the movable rollers 5 to adapt to copper strips of different thicknesses, achieve stable clamping and reliable guidance, and improve processing adaptability; 2. The drive motor 13 drives 4 sets of fixed rollers to rotate synchronously, realizing automatic feeding of copper strip and seamlessly connecting with the bending station, effectively improving the overall production efficiency; 3. The movable and locking mechanical limit frame 12-6 can accurately set and control the end point of the stroke of the actuating plate 12-4, thereby ensuring the accuracy and consistency of the copper strip bending angle. 4. The torsion spring force is used to make the push rod 9 component automatically and quickly reset after completing a single bend, preparing for the next bend action, thus realizing rapid and continuous cyclic production.

[0024] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features.
