Description

Technical Field

[0001] This invention specifically relates to a copper-aluminum composite strip continuous winding equipment and continuous winding production method, and pertains to the field of copper-aluminum composite strip production technology. Background Technology

[0002] See attached document Figure 1 Most existing copper-aluminum composite strips are produced using a solid-liquid composite method. This method involves coating copper strip 1 onto semi-solidified molten aluminum 2, and then rolling the strip with rolls 4 to bond the copper and aluminum together. The main drawback of the solid-liquid composite method is that it cannot be used continuously. This is because while molten aluminum can be continuously produced, the length of the copper strip is limited. When the copper strip is almost used up, the machine needs to be stopped to replenish it with new strip.

[0003] See attached document Figure 2 Because copper is difficult to solder, the current method for splicing copper strips involves drilling holes in two copper strips 1 and then using multiple studs 3 to connect the two strips together. Currently, splicing copper strips requires manual work by workers, which is not only time-consuming and labor-intensive but also significantly delays production. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention discloses a copper-aluminum composite strip continuous winding equipment and continuous winding production method, which is mainly used to solve the problems of time-consuming and labor-intensive copper strip splicing and production delay in the prior art.

[0005] The present invention adopts the following technical solution: A copper-aluminum composite strip continuous winding equipment and continuous winding production method are disclosed, comprising a continuous winding device for connecting two copper strips together by means of climbing nails. The continuous winding device mainly consists of a frame, a lifting slider, a bending slider, and a top pressure block. The frame has a horizontally arranged platform and a vertically arranged column, with a groove provided on the platform. The lifting slider can slide up and down along the column under the push of power, and multiple pairs of electric drills are installed on the lifting slider. The bending slider is located in the groove and can slide left and right under the push of power. The top pressure block is located above the platform and can move up and down under the push of power. When changing rolls, the top pressure block presses the ends of the two copper strips tightly onto the table. Then, the lifting slider moves upward, allowing multiple pairs of electric drills to drill holes in the ends of the two copper strips simultaneously. Then, the climbing nail is placed into the drilled holes, and the two copper strips are connected together by bending the climbing nail through the bending slider, thus realizing the continuous production of copper-aluminum composite strips.

[0006] Further improve the technical solution: A hydraulic cylinder is installed between the platform and the lifting slider, and the hydraulic cylinder is used to push the lifting slider to slide up and down along the column.

[0007] Further improve the technical solution: A bending cylinder is installed between the platform and the bending slider. The bending cylinder is used to push the bending slider to bend the climbing nail.

[0008] Further improve the technical solution: The top pressure block is connected to the top pressure cylinder, and the top pressure cylinder is used to push the top pressure block downward to press the climbing nail.

[0009] Further improve the technical solution: a through groove is provided on the top pressure block to avoid the drill bit.

[0010] Further improvements to the technical solution include a pair of drums and a pair of rollers set on one side of the platform, with the drums and rollers positioned above and below the platform.

[0011] After implementing the above technical solution, the beneficial effects of the present invention compared with the prior art are as follows: The continuous winding equipment of the present invention can replace manual labor to automatically connect two copper strips, which not only saves time and labor, but also reduces production costs.

[0012] The continuous winding production method of the present invention does not require intermediate shutdowns, enabling continuous production of copper-aluminum composite strips, which not only improves production efficiency but also reduces energy consumption caused by downtime.

[0023] A continuous winding device and method for copper-aluminum composite strip are disclosed, relating to the field of copper-aluminum composite strip production technology. It is mainly used to connect two copper strips together via climbing studs, thereby enabling continuous production of copper-aluminum composite strips. The composition and working principle of this invention are described in detail below.

[0024] See attached document Figure 3-5 The continuous winding equipment 7 mainly consists of a frame 71, a lifting slider 72, a bending slider 75, and a top pressure block 77. The frame 71 has a horizontally arranged platform 711 and four vertically arranged columns 712. Three pairs of sliding grooves are provided on the platform 711.

[0025] A pair of drums 6 and a pair of rollers 5 are arranged on the left side of the frame 71, with the drums 6 and rollers 5 positioned vertically relative to the frame 711. Copper strip 1 is wound on the drums 6. When the copper strip on one drum is almost used up, it is removed from the drum, and the end of the copper strip is placed on the frame 711. Then, the head end of the copper strip on the other drum is also placed on the frame 711, aligned with the end of the previous copper strip 1. A pair of rollers 5 are arranged on the right side of the frame 71, their function being to clamp the copper strip 1, causing it to enter the roll gap at an angle while taut. Because the previous copper strip 1 has a relatively large reserved length, the two copper strips 1 can be spliced ​​without stopping the machine.

[0026] The lifting slider 72 is slidably mounted on four columns 712. Three pairs of electric drills 73 are mounted on the lifting slider 72, with the drill bits of the drills 73 pointing upwards. The distance between each pair of drills 73 is equal to the length of the climbing nail 3, ensuring that the climbing nail 3 can be smoothly placed into the drill hole. A hydraulic cylinder 74 is installed between the platform 71 and the lifting slider 72. The function of the hydraulic cylinder 74 is to push the lifting slider 72 to slide up and down along the columns 712, thereby drilling holes in the two copper strips 1.

[0027] The bending slider 75 is slidably disposed in the groove. A bending cylinder 76 is disposed between the platform 711 and the bending slider 75. The function of the bending cylinder 76 is to push the bending slider 75 to bend the climbing nail 3.

[0028] The pressure block 77 is positioned above the table 711, and a through groove is provided on the pressure block 77 to avoid the drill bit. The pressure block 77 is connected to the pressure cylinder 78, which presses the copper strip 1 or the climbing nail 3 downward.

[0029] See attached document Figure 6 When drilling, first place the seams of the two copper strips 1 at the front and back between the three pairs of electric drills 73, then push the top pressure block 77 downward through the top pressure cylinder 78 to press the copper strip 1 onto the table 711, and then push the lifting slider 72 upward through the hydraulic cylinder 74, while simultaneously turning on the electric drills 73 to drill holes in the two copper strips 1 at the front and back.

[0030] See attached document Figure 7 After drilling, lower the lifting slider 72 and raise the top pressure block 77 to make room, and then put the climbing nail 3 into the drilled hole.

[0031] See attached document Figure 8 First, the top-pressing cylinder 78 pushes the top-pressing block 77 downward, pressing the climbing nail 3 onto the platform 711. Then, the bending cylinder 76 pushes the bending slider 75 horizontally to bend the climbing nail 3, thereby connecting the front and rear copper strips 1 together. Finally, the top-pressing block 77 is moved upward to complete the connection of the front and rear copper strips 1.

[0032] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this invention should be included within the scope of protection of this invention.
