Description

Technical Field

[0001] The invention relates to the technical field of workpiece bending, and more specifically to a copper sheet bending tool. Background Art

[0002] In switch products, it is often necessary to use Figure 3 In the copper sheet shown, two sides of the copper sheet (1) are bounded by a bending line (12), and two pairs of symmetrical bending edges (11) are extended. Both pairs of bending edges (11) need to be bent vertically upward. This copper sheet with a bend is much more expensive than an unfolded copper sheet without a bend. However, before assembly, an operator is required to bend the part to be bent upward for the unfolded copper sheet without a bend. When bending, the operator manually bends the copper sheet along the bending line, and the folded product has poor consistency. In addition, because the copper sheet is very thin, the bending defect rate is high, and the product processing time is also relatively long. Utility Model Content

The two sides of the copper sheet are bounded by a bending line, and two pairs of symmetrical bending edges are extended. The copper sheet is also provided with perforations. The tool includes: a pressure plate and a bottom plate that are arranged in conjunction with each other. The pressure plate presses the copper sheet against the bottom plate along the bending line, and the side edges of the pressure plate and the bottom plate extend from the bending edges on both sides of the copper sheet.

[0006] Furthermore, two sides of the bottom plate are rotatably connected with bending rocker arms through a pin shaft pair, and the bending rocker arms correspond to the two pairs of bending edges one by one and are arranged in coordination.

[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] A copper sheet bending tool of this embodiment is applied to the bending of an existing copper sheet 1, such as Figure 3 , 4 As shown, the two sides of the copper sheet 1 are bounded by the bending line 12, extending into two symmetrical pairs, a total of four bending edges 11, and the copper sheet 1 is also provided with two through holes 13, an arc hole and a square opening.

[0027] like Figure 1 , 2 As shown, the tooling includes: a pressure plate 2 and a bottom plate 3 that are arranged in coordination, the pressure plate 2 presses the copper sheet 1 on the bottom plate 3 along the bending line 12, and the bending edges 11 on both sides of the copper sheet 1 extend from the side edges of the pressure plate 2 and the bottom plate 3.

[0028] To further explain how to achieve accurate and positioned clamping:

[0029] The pressing plate 2 and the bottom plate 3 are respectively provided with a limiting hole 21 and a positioning boss 33 that match the position of the through hole 13 .

[0030] The pressing plate 2 and the bottom plate 3 are also provided with positioning holes and positioning pins 35 for cooperating in pressing and positioning.

[0031] In order to achieve stable clamping: the positioning boss 33 is provided with a vertical threaded hole 331 , and through the cooperation between the screw and the threaded hole 331 , the pressing plate 2 presses the copper sheet 1 onto the bottom plate 3 along the bending line 12 .

[0032] In order to achieve accurate, labor-saving and consistent clamping: the two sides of the bottom plate 3 are rotatably connected with bending rocker arms 32 through a pin shaft pair 34, and the bending rocker arms 32 correspond to the two pairs of bending edges 11 one by one and are arranged in coordination.

[0033] In specific operations,

[0034] 1. Place the copper sheet 1 to be bent on the assembled tooling. The bottom plate 3 and the bending rocker arm 32 are assembled together through the pin shaft pair 34. The positioning boss 33 on the tooling is set according to the size of the matching perforation 13. Just align the copper sheet 1 and place it on.

[0035] 2. After the copper sheet 1 is placed, the pressing plate 2 is assembled. During assembly, the positioning pin holes on the pressing plate 2 need to be aligned with the positioning pins 35 on the bottom plate, and then the bottom plate 3 and the pressing plate 2 are locked with the screws locked in the threaded holes 331. At the same time, the copper sheet 1 is pressed to prevent the copper sheet from shifting during bending, resulting in the production of defective and substandard products.

[0036] 3. Fold the rotating rocker arm 32 upward, bend the two pairs of bent edges 11 vertically upward, remove the locking screws locked by the threaded holes 331 after the bending is completed, remove the pressing plate 2, and remove the bent copper sheet 1.
