Description

Technical Field

[0001] This utility model relates to the field of nickel sheet bending technology, specifically a nickel sheet bending tool. Background Technology

[0002] In the manufacturing process of soft copper busbars, some models require nickel plating on both sides of the welding area, and the length of the upper and lower nickel plating layers must be consistent to ensure good conductivity, welding reliability, and consistent appearance. Currently, conventional processing methods typically involve clamping two independent nickel sheets onto the upper and lower surfaces of the soft copper busbar before welding. This process suffers from difficulties in clamping and positioning, poor nickel sheet alignment accuracy, and difficulty in effectively ensuring the consistency of the upper and lower nickel plating lengths. Furthermore, the sectional operation is cumbersome, with large repeated positioning errors, resulting in low overall processing efficiency and insufficient product quality stability. Therefore, a nickel sheet bending fixture is proposed. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4In this embodiment of the utility model, a nickel sheet bending fixture includes a fixed base 1 and a limiting slide 2. The fixed base 1 has a bending groove 101. There are two limiting slides 2, which are set on the fixed base 1 and a gap is reserved between the two limiting slides 2. The gap coincides with the bending groove 101. Each of the two limiting slides 2 is equipped with a limiting slider 4 for limiting the position of the nickel sheet. A pressing head 8 for pressing and bending the nickel sheet is set above the bending groove 101.

[0016] Specifically, the upper surface of the fixed base 1 has a square groove that runs through the front and rear ends, and the bending groove 101 is located in the middle of the square groove. The two limiting slides 2 are located inside the square groove and can move within the square groove. The distance between the two limiting slides 2 is adapted to the end of the pressing head 8, so that the nickel sheet laid flat on the limiting slide 2 can be bent. The limiting slider 4 can restrict the nickel sheet in three directions to ensure that it will not deviate during the bending process and ensure that the length of the nickel sheet on both sides is basically the same after bending.

[0017] Please see Figure 2 and Figure 4 In one embodiment, preferably, the bottom of the fixed base 1 is provided with a hollow groove 102, the hollow groove 102 is provided with an elastic component 7 inside, and the hollow groove 102 is connected to the bending groove 101. Furthermore, the hollow groove 102 is configured to provide a hidden placement space for the elastic component 7, and also to reserve space for the downward pressing of the nickel sheet, so as to ensure that the nickel sheet can be pressed down smoothly.

[0018] Please see Figure 2 In one embodiment, preferably, the elastic component 7 includes a base plate 71 installed inside the hollow groove 102. A spring 72 is installed on the base plate 71, and a spring-loaded pin 73 is installed at the end of the spring 72 away from the base plate 71. Further, in the initial state, the top of the spring-loaded pin 73 is in close contact with the upper wall of the hollow groove 102. When the pressing head 8 presses down, it causes the nickel sheet to bend. As the pressing head 8 continues to press down, the spring-loaded pin 73 also moves down. After the nickel sheet is bent, the pressing head 8 moves back up. At this time, the bent nickel sheet resets the position of the spring-loaded pin 73 under the elastic force of the spring 72, causing the bent nickel sheet to move up synchronously, which is convenient for the staff to pick up later.

[0019] Please see Figure 1In one embodiment, preferably, the limiting slide 2 is provided with a plurality of limiting grooves 201, and limiting bolts 3 are installed inside the limiting grooves 201. The limiting bolts 3 pass through the limiting slide 2 and are connected to the fixed base 1. Furthermore, the side wall where the two limiting slides 2 are connected is set to an arc shape, which can reduce the wear on the nickel sheet during the bending process compared with the right angle side. In addition, the limiting grooves 201 are two layers of grooves with different inner diameters. The vertical movement of the limiting slide 2 can be restricted by the cooperation of the limiting bolts 3 and the limiting grooves 201.

[0020] Please see Figure 1 In one embodiment, preferably, the fixed base 1 is equipped with an adjusting bolt 6 that is rotatably connected to the limiting slide 2. Furthermore, by rotating the adjusting bolt 6, the limiting slide 2 can be moved horizontally to adjust the distance between the two limiting slides 2, and the moving direction of the limiting slide 2 is consistent with the length direction of the limiting groove 201.

[0021] Please see Figure 1 In one embodiment, preferably, the limiting slider 4 is provided with an adjustment groove 401, and a fastening bolt 5 connected to the limiting slide 2 is installed in the adjustment groove 401. Furthermore, the position of the limiting slider 4 on the limiting slide 2 can be adjusted, thereby limiting and fixing nickel sheets of different sizes.

[0022] Please see Figure 1 In one embodiment, preferably, the limiting slider 4 is an L-shaped structure. Furthermore, the L-shaped structure can limit the nickel sheet in two directions, so only two limiting sliders 4 are needed to effectively fix the flat nickel sheet.

[0023] Please see Figure 1 In one embodiment, preferably, a protective sleeve 9 is installed on the top of the lower pressure head 8, and a mold handle 10 is installed inside the protective sleeve 9. Furthermore, the mold handle 10 can be replaced according to different pressure devices.

[0024] Working principle and usage process of this utility model: First, place the cut nickel sheets of equal length and thickness (0.1mm) on the limiting slide 2, and rotate the adjusting bolt 6 to adjust the spacing of the limiting slide 2 so that it matches the end of the pressing head 8. Then, adjust the position of the upper limit slider 4 of the limiting slide 2 so that the three sides of the nickel sheet are restricted by the limiting slider 4. Then, rotate the fastening bolt 5 to fix its position, and at the same time, align the transverse center line of the nickel sheet with the bending groove 101 on the fixed base 1. Then, the pressing head 8 presses down, causing the nickel sheet to move downward. Under the restriction of the two limiting slides 2, the nickel sheet is bent and formed. At the same time, the spring pin 73 also moves downward. At this time, the spring 72 is compressed. When the pressing head 8 returns to its original position, the spring pin 73 returns to its original position under the action of the spring 72. At this time, the nickel sheet is ejected, making it easy for the staff to remove it. It is then used to completely adhere to the top and bottom surfaces after being combined with the copper foil, ensuring that the nickel sheet on the bottom side does not fall off or leak during the welding process, and ensuring that the length of the nickel sheets on both sides is basically the same.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
