[0002] In electrical equipment, copper busbars serve as crucial conductive connectors, widely used in devices such as steering motors. This design utilizes a tool for bending three types of ring-shaped and three types of L-shaped copper busbars. This simple bending tool provides numerous advantages for positioning the busbars. It ensures precise positioning during the bending process, improving bending accuracy and consistency. This prevents scrap caused by misalignment, improves work efficiency, and provides reliable quality assurance for busbar processing.

[0003] In the existing technology, some simple bending tooling is often used.

When producing samples, traditional bending tooling is often more complicated in design and has cumbersome operating steps, requiring the operator to have a certain level of technical skills. Therefore, a simple bending tool is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3The utility model provides an embodiment: a simple bending tool, including an upper bending cover plate 1, which is an important component of the entire simple bending tool. It is usually made of high-strength metal material with a certain thickness and rigidity. The right side of the upper bending cover plate 1 is slidably connected with a positioning block 2, which is in the shape of a rectangular parallelepiped. At the same time, the positioning block 2 can provide a fulcrum for subsequent workpieces. A limiting groove 11 is provided inside the positioning block 2, which can limit subsequent workpieces. The right side of the upper bending cover plate 1 is threadedly connected with a locking nut 3, which can limit the positioning block 2 through the locking nut 3. The internal thread of the positioning block 2 is connected with a positioning screw 4, which can be extended and retracted inside the positioning block 2 through the positioning screw 4. The external thread of the positioning screw 4 is connected with a nut 16, and the external thread of the positioning screw 4 is connected with a nut 16. The threaded connection is provided with nut 2 5, and the right side of nut 16 fits with the left side of nut 2 5. The nut 2 5 and the nut 16 cooperate with each other to enable the positioning screw 4 to be tightened by nut 2 5 and nut 16. The left side of nut 16 fits with the right side of the positioning block 2. The nut 16 can achieve the effect of mutual tightening with the positioning block 2. The internal sliding connection of the upper bending cover 1 is provided with an annular bending pressing block 6, through which the annular copper bar can be bent. The internal sliding connection of the upper bending cover 1 is provided with an L-shaped bending pressing block 7, and the L-shaped bending pressing block 7 can process the long copper bar into an L shape.

[0032] Reference Figure 1 and Figure 4 The inner sliding connection of the upper bending cover plate 1 is provided with a positioning component for convenient processing of subsequent workpieces. The positioning component includes two positioning pins 10. The outer sliding connection of the positioning pins 10 is connected to the inner part of the upper bending cover plate 1. The positioning pins 10 can slide in the upper bending cover plate 1 and the subsequent workpiece to prevent deviation during processing. The outer bottom end of the positioning pin 10 is slidably connected to the lower bending cover plate 12. The positioning pins 10 can slide inside the lower bending cover plate 12, and the bottom of the upper bending cover plate 1 is fitted with the top of the lower bending cover plate 12, so that the upper bending cover plate 1 and the lower bending cover plate 12 can be connected to each other to prevent separation during processing. The top of the lower bending cover plate 12 is fixedly connected to the limiting block 13, and the annular copper bar can be positioned by the limiting block 13;

[0033] An L-shaped groove 14 is provided on the top of the lower bending cover 12. The L-shaped groove 14 can be used to put the copper busbar and then bend it. The bottom of the annular bending block 6 slides inside the L-shaped groove 14. The bottom end of the L-shaped bending block 7 is slidably connected to the inside of the L-shaped groove 14. The annular bending block 6 and the L-shaped bending block 7 can be used to bend the copper busbar inside the L-shaped groove 14 through a manual press. The operator will measure the size after bending and fine-tune the subsequent workpiece according to the measurement results to ensure that the bending accuracy of each L-shaped copper busbar meets the requirements. The top left side of 12 is fixedly connected with a clamping block 15, which can be engaged with the upper bending cover plate 1 through the clamping block 15. The inner top of the upper bending cover plate 1 is threadedly connected with a locking screw 1 8, and the inner top of the upper bending cover plate 1 is threadedly connected with a locking screw 2 9. The outer bottom end of the locking screw 1 8 is threadedly connected to the inside of the lower bending cover plate 12, and the outer bottom end of the locking screw 2 9 is threadedly connected to the inside of the lower bending cover plate 12. Through the cooperation of the locking screw 1 8 and the locking screw 2 9, the operator can adjust it to a loose state and easily perform bending. After bending is completed, the copper busbar can be directly poured out and then a new copper busbar can be inserted, avoiding the tedious process of repeated assembly, thereby significantly improving production efficiency;

[0034] The outer part of the locking nut 3 is slidably connected to the inside of the limiting groove 11. The locking nut 3 can slide inside the limiting groove 11, so that the limiting groove 11 can be limited, so that the positioning block 2 can move downward, and the left side of the positioning screw 4 contacts the right side of the lower bending cover 12. When the positioning block 2 descends, the positioning screw 4 can be driven to descend, and at the same time, the positioning screw 4 can be extended to achieve the effect of positioning the lower bending cover 12.

[0035] Working principle: When the copper busbar needs to be processed, first loosen the nut 2 5 and the nut 1 16 to loosen the positioning block 2. When the positioning block 2 is loosened, it will slide down. The locking nut 3 can achieve the limiting effect. When the positioning block 2 falls to the required position, the locking nut 3 is twisted to make one end of the positioning block 2 contact. The positioning block 2 is positioned once when it falls. The positioning screw 4 can be driven to fall when the positioning block 2 falls. The threaded connection of the positioning screw 4 can move inside the positioning block 2, so that the positioning block 2 can resist the L-shaped groove 14. At the same time, the positioning screw 4 and the positioning block 2 are fastened to each other by tightening the nut 2 5 and the nut 16.

[0036] When the copper busbar is inside the L-shaped groove 14, the L-shaped bending block 7 is squeezed by a manual press. When the copper busbar is squeezed, it is bent to easily achieve a 90° bending angle. This design not only simplifies the operating steps, but also improves the repeatability and consistency of the bending. At the same time, through the locking screw 1 8 and the locking screw 2 9, the operator can adjust it to a loose state and easily bend it. After the bending is completed, the copper busbar can be directly poured out and then a new copper busbar can be inserted, avoiding the tedious process of repeated assembly. Secondly, the upper bending cover plate 1 and the lower bending cover plate 12 can be connected and installed with each other through two positioning pins 10 to prevent position displacement during processing.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
