Description

Technical Field

[0001] The utility model belongs to the technical field of copper busbar processing, and particularly relates to a copper busbar forming device. Background Art

[0002] Copper busbars, as a crucial conductive material, are widely used in the power, electrical, and electronics industries due to their excellent conductivity, corrosion resistance, and mechanical strength. Z-shaped copper busbars, in particular, are critical connectors in the manufacturing of power equipment such as large transformers, switchgear, and busbars. Their quality and production efficiency directly impact the overall product performance and market competitiveness. However, traditional copper busbar bending processes, which primarily rely on manual or semi-automatic equipment, present numerous shortcomings.

[0003] First, manual bending is labor-intensive, inefficient, and difficult to achieve with guaranteed accuracy and consistency. Due to varying operator skill levels and fatigue levels, deviations in bending angle and shape often occur, impacting reliability during subsequent assembly and operation. Furthermore, manual bending can easily scratch and deform the copper busbar surface, reducing product quality.

[0004] Secondly, although semi-automatic bending equipment has improved production efficiency to a certain extent, it still has many limitations. For example, there are problems such as complex equipment structure, large floor space, and high maintenance costs. Utility Model Content

[0005] In view of the above problems, the purpose of the present invention is to provide a copper busbar forming device to solve the problems of the existing bending equipment used for copper busbar bending and forming, such as complex structure, large floor space and high maintenance cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a copper busbar forming device, comprising a support frame, side frames are installed at both ends of the support frame, a driving gear is rotatably installed on the support frame, the rotating shaft of the driving gear is connected to one end of the handle, the driving gear is meshed with the driven gear 1 and the driven gear 2 on both sides, the driven gear 1 and the driven gear 2 are respectively rotatably sleeved on two positioning pins, the positioning pins are installed on the support frame, a rotating groove is opened through the support frame, a bending rod is slidably inserted in the rotating groove, and the bending rod is installed on the driven gear 1 and the driven gear 2.

[0007] The beneficial effects of the utility model are as follows: two sets of gear transmission are adopted, and the one-time Z-shaped bending of the copper bar sheet can be achieved through simple handle operation; and the device has a compact structure and is easy to operate, which not only improves production efficiency, but also ensures high precision and consistency of bending, and effectively reduces labor intensity and equipment maintenance costs.

[0008] In order to quickly and easily bend the copper busbar;

[0009] As a further improvement of the above technical solution: the specifications of the driven gear 1 and the driven gear 2 are the same, and the gear transmission structure composed of the driving gear, the driven gear 1 and the driven gear 2 is a speed increasing mechanism.

[0010] The beneficial effect of this improvement is that the operator only needs to rotate the handle within a relatively small range to rotate the driven gear 1 and the driven gear 2 90 degrees, thereby quickly processing a Z-shaped copper busbar.

[0011] In order to effectively improve the compactness of the device;

[0012] As a further improvement of the above technical solution: one end of the handle is a screw structure, and an internal threaded hole structure for threaded connection with the handle is provided through the side surface of the rotating shaft of the driving gear.

[0013] The beneficial effect of this improvement is that the handle can be easily removed from the driving gear, thereby effectively reducing the size of the device and making it easier to carry and use the device.

[0014] In order to ensure the stability of the device;

[0015] As a further improvement of the above technical solution: the side bracket is an angle steel structure, and a through hole structure for inserting bolts is provided on the flange of the side bracket parallel to the upper and lower end surfaces of the support frame.

[0016] The beneficial effect of this improvement is that the side bracket can be stably fixed to the support surface by bolts, thereby ensuring the stability of the device during use.

[0017] In order to conveniently use this device for bending operations;

[0018] As a further improvement of the above technical solution: the bottom surface of the driving gear is eccentrically connected to one end of a return spring, and the other end of the return spring is connected to a support frame.

[0019] The beneficial effect of this improvement is that when the driving gear rotates to perform the bending operation, the reset spring is stretched to generate elastic energy storage. After the bending is completed, the reset spring releases the elastic potential energy, driving the driving gear to quickly reset, making it convenient for personnel to perform the next bending operation.

[0020] In order to avoid structural interference between the bending rod and the support frame during the rotation process;

[0021] As a further improvement of the above technical solution: the rotation groove is an arc-shaped groove structure, and the axis of the rotation groove is collinear with the axis of the positioning pin.

[0022] The beneficial effect of this improvement is that during the rotation of the driven gear 1 and the driven gear 2, the bending rod can move smoothly and synchronously in the rotation groove to perform stable bending work.

[0023] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-3 shows: a copper bar forming device, including a support frame 1, with side brackets 3 installed at both ends of the support frame 1, a driving gear 4 is rotatably installed on the support frame 1, the rotating shaft of the driving gear 4 is connected to one end of the handle 5, the driving gear 4 is meshed with the driven gear 1 6 and the driven gear 2 7 on both sides, the driven gear 1 6 and the driven gear 2 7 are respectively rotatably sleeved on two positioning pins 8, the positioning pins 8 are installed on the support frame 1, and a rotation groove 11 is opened through the support frame 1, and a bending rod 10 is slidably inserted in the rotation groove 11, and the bending rod 10 is installed on the driven gear 1 Two sets of gear transmission are used on the gear 1 6 and the driven gear 2 7, and the one-time Z-bending of the copper bar sheet can be achieved by simple handle operation; and the device has a compact structure and is easy to operate, which not only improves the production efficiency, but also ensures high precision and consistency of bending, effectively reduces the labor intensity and equipment maintenance cost, the specifications of the driven gear 1 6 and the driven gear 2 7 are the same, and the gear transmission structure composed of the driving gear 4 and the driven gear 1 6 and the driven gear 2 7 is a speed-increasing mechanism, and the operator only needs to turn the handle 5 within a small range to make the driven gear 1 6 and the driven gear 2 7 rotates 90 degrees to quickly process the Z-shaped copper bar 2. One end of the handle 5 is a screw structure. The side of the rotating shaft of the driving gear 4 is provided with an internal threaded hole structure for threaded connection of the handle 5. The handle 5 can be easily removed from the driving gear 4, thereby effectively reducing the volume of the device and facilitating the portability of the device. The side bracket 3 is an angle steel structure. The flanges of the side bracket 3 parallel to the upper and lower end surfaces of the support frame 1 are provided with a through-hole structure for inserting bolts. The side bracket 3 can be stably fixed to the support surface by bolts, thereby ensuring the stability of the device. The driving gear 4 The bottom surface is eccentrically connected to one end of the return spring 9, and the other end of the return spring 9 is connected to the support frame 1. When the driving gear 4 rotates to perform the bending operation, the return spring 9 is stretched to generate elastic energy storage. After the bending is completed, the return spring 9 releases the elastic potential energy, driving the driving gear 4 to quickly reset, making it convenient for personnel to perform the next bending operation. The rotating groove 11 is an arc groove structure, and the axis of the rotating groove 11 is collinear with the axis of the positioning pin 8. During the rotation of the driven gear 1 6 and the driven gear 2 7, the bending rod 10 can move smoothly and synchronously in the rotating groove 11 to perform stable bending work.

[0031] The working principle of this technical solution is as follows: when in use, first try to fix the side bracket 3 on a stable support surface with bolts, then thread the handle 5 to the rotating shaft of the driving gear 4, and then place the square plate-shaped copper bar 2 between the two sets of positioning pins 8 and the bending rod 10, so that the two ends of the copper bar 2 are against the side surfaces of the side bracket 3, and rotate the driving gear 4 by the handle 5. The driving gear 4 engages and drives the driven gear 1 6 and the driven gear 2 7 on both sides to rotate, and the driven gear 1 6 and the driven gear 2 7 drive the bending rod 10 to rotate around the axis of the positioning pin 8, thereby quickly bending the copper bar 2 into a Z-shaped copper bar shape at one time. After bending, the processed copper bar 2 is taken out upward, and the driving gear 4 is quickly reset under the drive of the reset spring 9.
