[0032] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0033] Please refer to Figures 1 to 5 , this application provides a copper bar bending tooling, which includes a base 1, a fixing station 2, a twisting member 3, a processing station 4, and a bending station 5. Among them, the fixing station 2 is arranged on the base 1 and is used for positioning the copper bar to be bent. The twisting member 3 is used to drive the copper bar positioned by the fixing station 2 to twist to generate a bend. A clamping groove 31 is arranged on the twisting member 3, and at least part of the copper bar can be clamped into the clamping groove 31. The processing station 4 is arranged on the base 1 and is used to cooperate with the twisting member 3 to twist the copper bar. The bending station 5 is arranged between the fixing station 2 and the processing station 4.

[0034] When processing a copper bar, first place the copper bar on the base 1. When placing, one end of the copper bar is placed on the fixing station 2, and the position to be twisted and bent corresponds to the bending station 5, and the copper bar on the rear side (the side away from the fixing station 2) of the position to be twisted and bent is clamped into the clamping groove 31 on the twisting member 3. Then manually turn the twisting member 3 to cooperate with the fixing station 2 to apply a twisting force to the copper bar, and the part of the copper bar in the bending station 5 is twisted and bent after twisting. From the above structure and the copper bar processing process, it can be seen that the entire tooling structure is simple, the manufacturing cost is low, and the manufacturing cycle is fast; moreover, by manually turning the twisting member 3 to realize the rotary bending of the hard copper bar, all dimensional data tend to be stable, and the product consistency can be guaranteed.

[0035] Specifically, the twisting member 3 includes a twisting head 32 and a twisting arm 33. Among them, the twisting arm 33 is connected to the twisting head 32, and the clamping groove 31 is arranged on the twisting head 32. By turning the twisting arm 33 to drive the twisting head 32 to drive the copper bar to twist, the operation is more convenient and labor-saving.

[0036] Furthermore, the processing station 4 includes a processing seat 41 and a slot 42 provided on the processing seat 41. The slot 42 is used to place the twisting head 32, and the twisting head 32 and the slot 42 are rotationally matched. When the twisting arm 33 is pulled, the twisting head 32 can rotate relative to the slot 42, thereby driving the copper bar to twist. The slot 42 limits the position of the twisting head 32 to prevent the twisting head 32 from being offset in the process of twisting the copper bar, thereby ensuring the consistency of the bending of the copper bar obtained by processing and improving product quality.

[0037] Preferably, the inner wall of the slot 42 is a curved surface structure, and the outer wall of the twisting head 32 is a curved surface structure. The curved surfaces cooperate with each other, so that the twisting head 32 rotates more smoothly relative to the slot 42.

[0038] In one embodiment, the processing station 4 further includes a rotating shaft 43 and a pressing piece 44. The rotating shaft 43 is disposed on the processing seat 41, and the pressing piece 44 is connected to the rotating shaft 43 and can rotate relative to the rotating shaft 43 around the axis of the rotating shaft 43.

[0039] It is understandable that during the circumferential rotation of the pressing piece 44 relative to the rotating shaft 43, a part of the pressing piece 44 will rotate to the upper position of the slot 42, thereby limiting the position of the twisting head 32 placed in the slot 42, effectively preventing the twisting head 32 from falling out of the slot 42 during the rotation relative to the slot 42, and reducing the failure rate. When the pressing piece 44 rotates to a position away from the slot 42, the twisting head 32 can be taken out of the slot 42, which will not affect the assembly of the copper bar and the slot 31 on the twisting head 32.

[0040] Exemplarily, the rotating shaft 43 is a bolt, a screw, etc. The pressing piece 44 is configured as a block structure.

[0041] Further, the twisting arm 33 includes a twisting block 331 and an extension rod 332. The twisting block 331 is connected to the twisting head 32, and the extension rod 332 is arranged on a side of the twisting block 331 away from the twisting head 32.

[0042] In this way, the extension rod 332 increases the length of the force arm, and when driving the twisting head 32 to rotate and twist the copper bar, a lever-like principle is realized, thereby saving more effort in operation.

[0043] Furthermore, a notch groove 45 is provided on the processing seat 41 at a position corresponding to the twisting block 331 to ensure that the existence of the processing seat 41 will not block the turning of the twisting arm 33, thereby increasing the twisting range of the copper bar.

[0044] Specifically, the fixed station 2 includes a fixed base 21, a fixed block 22, a moving block 23 and a locking member 24. Among them, the fixed base 21 and the fixed block 22 are both fixed on the fixed base 21, and the moving block 23 is slidably arranged on the fixed base 21. A fixing groove 25 is provided between the fixed block 22 and the moving block 23. The locking member 24 is arranged on the fixed base 21 and is used to position the moving block 23 on the fixed base 21.

[0045] Understandably, during processing, the end of the copper bar is placed in the fixing groove 25. The moving block 23 moves closer to the fixed block 22, and the position of the moving block 23 is fixed by the locking member 24, thereby clamping the copper bar. The sliding direction of the moving block 23 is the width direction of the fixing groove 25. That is, the moving block 23 can move closer to or away from the fixed base 21, thereby changing the width of the fixing groove 25 to adapt to copper bars of different thicknesses.

[0046] Furthermore, a first screw hole 211 is provided on the fixed base 21, and the first screw hole 211 penetrates the fixed base 21 along the moving direction of the moving block 23. A second screw hole 231 is provided on the moving block 23, and the second screw hole 231 is arranged on the side of the moving block 23 away from the fixed block 22. The locking member 24 is provided with a threaded section, and the threaded section is screwed with the first screw hole 211 and the second screw hole 231.

[0047] When the locking member 24 rotates, through the threaded cooperation of the threaded section with the first screw hole 211 and the second screw hole 231, the locking member 24 can move relative to the fixed base 21 in a direction closer to or away from the moving block 23, thereby pushing the moving block 23 to move in a direction closer to or away from the fixed block 22, so as to adjust the position of the moving block 23. The overall structure is simple, the operation is convenient, and the positioning is firm.

[0048] Exemplarily, the locking member 24 can be a bolt.

[0049] In an embodiment, the fixed station 2 further includes a connecting member 26. The fixed block 22 and the fixed base 21 are fixedly connected to the base 1 through the connecting member 26. Thus, the detachable connection of the fixed block 22 and the fixed base 21 relative to the base 1 is realized, which is convenient for replacing the fixed block 22 of different sizes, so as to adapt to the processing of different copper bars.

[0050] Exemplarily, the connecting member 26 can be a bolt, a screw, etc. The fixation of two components, namely the fixed block 22 and the fixed base 21, is realized through one connecting member 26, and the structure is simpler.

[0051] Furthermore, there is a spacing between the above-mentioned fixed base 21 and the processing base 41. A bending station 5 is formed by enclosing the side wall of the fixed base 21, the side wall of the processing base 41 and the upper surface of the base 1. Thus, the copper bar located at this position will be suspended, making it easier to achieve a twist and bend.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
