Description

TECHNICAL FIELD

[0001] The utility model relates to bar bending processing technical field especially, a simple and easy bending bar tool. BACKGROUND

[0002] The simple and easy bending bar tool is a tool used for bending and forming metal bars in manual or small-scale mechanical processing. This kind of tool is usually designed simply and is easy to operate, which is suitable for small-batch production or maintenance scenes that do not require extremely high precision but require rapid forming.

[0003] At present, most simple and easy bending bar tools adopt the form of manual bending machines. When using these manual bending machines, the operator needs to fix the metal bar with one hand and operate the bending tool with the other hand. This way has a high requirement for the coordination of the operator's hands, and the operation process is relatively complicated and time-consuming. In addition, during the bending process, due to human factors such as hand shaking or uneven force, the bending position and angle may deviate, thereby affecting the quality of the final product. More importantly, such operation also has certain safety risks, especially during rapid bending, which may cause safety accidents. SUMMARY

Detailed Implementation

[0019] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0020] Example: A simple tooling for bending bar stock, such as Figures 1-4 As shown, the device includes a base 1, a rotating disk 7, a fixed column 8, a positioning column 9, a limiting plate 22, a power assembly, and a clamping assembly. The rotating disk 7 is rotatably connected to the top left of the base 1. The fixed column 8 is connected to the top center of the rotating disk 7. Multiple second mounting holes 10 are provided on the front side of the top of the rotating disk 7. The positioning column 9 is fixed to one of the second mounting holes 10 by bolts. The gap between the fixed column 8 and the positioning column 9 is used for the bar to pass through. The rotation of both can bend one end of the bar. The limiting plate 22 is installed on the top of the base 1 at the right side of the fixed column 8. The limiting plate 22 and the front wall of the fixed column 8 are on the same straight line to ensure that the bar can accurately abut against the fixed column 8 when it is limited on the limiting plate 22. First mounting holes 2 are provided at the four corners of the top of the base 1 to facilitate fixing the device to the workbench with bolts. A clamping assembly for clamping the bar is provided on the front side of the top of the base 1. A power assembly for providing rotational power to the rotating disk 7 is provided inside the base 1.

[0021] like Figures 2-3 As shown, the power assembly includes a gear 3, a rack 4, and a first electric push rod 6. The first electric push rod 6 is bolted to the front side of the base 1. The rack 4 located inside the base 1 is connected to the telescopic rod of the first electric push rod 6. The bottom of the rotating disk 7 passes through the base 1 and is connected to the gear 3. The gear 3 meshes with the rack 4 to drive the rotating disk 7 to rotate.

[0022] like Figure 4 As shown, the clamping assembly includes a second electric push rod 12, a clamping plate 14, and a spring 15. The second electric push rod 12 is bolted to the top left front side of the base 1. The clamping plate 14 for clamping the bar is slidably connected to the telescopic rod of the second electric push rod 12. Two springs 15 are connected between the clamping plate 14 and the telescopic rod of the second electric push rod 12.

[0023] like Figure 1 and Figure 4As shown, it also includes a scale line 11, a top plate 17, a positioning plate 18, a guide rod 19, a screw 20, and a knob 21. The positioning plate 18 is welded to the top right side of the base 1. The guide rod 19 is symmetrically slidably connected to the positioning plate 18. The top plate 17, which is used to hold the right end of the bar, is connected between the left sides of the guide rod 19. The screw 20 is threadedly connected to the middle of the positioning plate 18. The left end of the screw 20 is rotatably connected to the top plate 17. The knob 21 is welded to the right end of the screw 20. The scale line 11 is provided on the front side of the top of the base 1. The starting position of the scale line 11 is on the left side of the positioning plate 18, which can indicate the distance between the top plate 17 and the positioning plate 18, so as to adjust the position of the bar on the base 1 according to the required bending length and position of the bar.

[0024] When performing bar bending, first determine the dimensions, bending angle, and diameter of the bar to be bent. Then, design the specific dimensions and structure of the tooling based on these parameters. When adjusting the diameter, the positioning post 9 is fixed to the second mounting hole 10 by bolts. There are multiple second mounting holes 10, and the position of the positioning post 9 can be adjusted according to the diameter of the bar to ensure that the distance between the fixing post 8 and the positioning post 9 can accommodate the bar.

[0025] Then, adjust the left and right positions of the top plate 17 according to the length and position of the bent bar. When placing the bar, ensure that the right end of the bar abuts against the top plate 17, and the left end of the bar passes through the gap between the fixed post 8 and the positioning post 9. The entire bar is limited by the positioning plate 22. In this way, the top plate 17 can play a positioning role each time the same batch of bars is placed. When adjusting the position of the top plate 17, turn the knob 21 in the forward or reverse direction to drive the screw 20 to rotate and move to the left or right, so as to drive the top plate 17 and the guide rod 19 to move synchronously. The scale line 11 serves as a reference, making the adjustment more precise.

[0026] Next, adjust the first electric push rod 6 according to the bending angle. The first electric push rod 6 is connected to an external controller, which can control the extension length of the telescopic rod of the first electric push rod 6 to adjust the rotation angle of the rotary disk 7. After adjusting all the components of the tooling, the bar can be placed on the base 1, with its right end abutting against the top plate 17, its left end limited between the fixed post 8 and the positioning post 9, and its rear and top limited by the limiting plate 22. Start the second electric push rod 12. The extension rod of the second electric push rod 12 extends and drives the clamping plate 14 to move backward, clamping the bar through the clamping plate 14. The spring 15 plays a buffering role and provides a certain clamping force. After fixing, start the first electric push rod 6. The telescopic rod extends according to the set parameters, driving the rack 4 to move to the left, which in turn drives the gear 3 and the rotating disk 7 to rotate, thereby driving the fixed column 8 and the positioning column 9 to rotate. These components then bend the left end of the bar stock. The bar stock is fixed by the limiting plate 22 and the clamping plate 14, ensuring stability during the bending process. After bending is complete, the first electric push rod 6 pauses. Then, the operator controls the telescopic rod of the second electric push rod 12 to shorten and reset, driving the clamping plate 14 to move forward and reset. The spring 15 rebounds and resets, releasing the clamping plate 14 from the bar stock, allowing it to be unloaded. The operator then controls the telescopic rod of the first electric push rod 6 to shorten and reset, moving the rack 4 back to its original position, causing the gear 3, rotating disk 7, fixed column 8, and positioning column 9 to reverse and reset. This process can be repeated to bend other bar stock.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
