Description

Technical Field

[0001] The utility model relates to the technical field of copper bar processing, in particular to a high-efficiency punching machine for copper bar processing. Background Art

[0002] Copper busbars are very important conductive products in the electrical industry. They can carry current and are not only used as the main trunk line for transmitting electrical energy within electrical switching equipment, but are also often used in scenarios such as equipotential connection in grounding systems.

[0003] Copper busbars have high mechanical strength and are not only easy to process but also have strong conductivity. The cost of copper busbars is much lower than precious metals with higher conductivity such as gold and silver, and their conductivity is much stronger than low-cost conductive metals such as aluminum and steel.

[0004] Copper busbars are widely used in the field of new energy vehicles. With the rapid development of the new energy vehicle industry, the processing of copper busbars has become more and more efficient and precise. Punching is a very important step in the processing of copper busbars. At present, the copper busbar processing punching machine has a large weight at the bottom, which causes great damage to the device during the lifting process. Repeated falling and impact and lifting often lead to problems such as short service life of the equipment. In addition, since the punching position is often located in the center of the copper busbar, the force at the center can easily cause the two sides of the copper busbar to warp up, affecting the accuracy of the copper busbar.

[0005] In order to solve the above problems, we made improvements and proposed an efficient punching machine for copper bar processing. Utility Model Content

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-3 As shown, a high-efficiency punching machine for copper bar processing includes a stable base 1, a stable bracket 2 and a recovery basket 17 are fixedly installed on the upper surface of the stable base 1, a fixed plate 9 is fixedly installed on the top of the stable bracket 2, sliding columns 3 are fixedly installed on both sides of the upper surface of the fixed plate 9, a slider 10 and a spring 12 are installed inside the sliding column 3, a top column 4 is fixedly installed on the top of the sliding column 3, a connecting shaft 6 and a transmission member 8 are rotatably installed between the top columns, and a mounting plate 13 and a punching assembly 14 are installed below the transmission member 8.

[0022] A reinforcing rib 16 is fixedly installed between the stabilizing bracket 2 and the fixing plate 9 to improve the stability of the punching machine during punching. A plurality of truncated cone-shaped through holes 18 are provided on the fixing plate 9. The diameter of the top of the through hole 18 is consistent with the punching assembly 14. The residual material after punching falls along the through hole 18 into the recovery basket 17 below.

[0023] The spring 12 is fixedly mounted on the inner bottom surface of the sliding column 3, and the end of the spring 12 is fixedly connected to the lower surface of the slider 10. The outer surface of the slider 10 is provided with edges and corners that match the inner surface of the sliding column 3 to prevent the slider 10 from shifting during continuous sliding. The slider 10 is slidably connected to the inner surface of the sliding column 3. When the slider 10 moves upward, the spring 12 provides it with a rebound force to reduce the pulling force during lifting.

[0024] A sliding groove is provided on the outer surface of the sliding column 3, and a connecting plate 11 is fixedly connected between the two sliding blocks 10. The lower surface of the connecting plate 11 is fixedly connected to the upper surface of the mounting plate 13, and the punching assembly 14 is fixedly connected to the lower surface of the mounting plate 13. The number and position of the punching assembly 14 correspond one-to-one to the through hole 18. When the punching assembly 14 falls, it will pass through the through hole 18 and impact the copper busbar placed on the mounting plate 13 to form a hole.

[0025] The bottom of the transmission member 8 is hinged to the connecting plate 11, and the top two sides of the transmission member 8 are rotatably connected with the first cams 7 respectively. The upper outer sides of the two first cams 7 are coaxially fixedly connected to the connecting shaft 6, and the connecting shaft 6 is rotatably connected to the top column 4. A servo motor 5 is fixedly installed on the outer surface of the top column 4. The rotating shaft of the servo motor 5 is coaxially fixedly connected to the connecting shaft 6. When the servo motor 5 drives the connecting shaft 6 to rotate, it also drives the first cam 7 to rotate. When the first cam 7 rotates, it will drive the transmission member 8 to move up and down, and at the same time pull the lower punching assembly 14 up and down continuously. When moving downward, since the mounting plate 13 and the punching assembly 14 themselves have a certain gravity, they can impact downward to make the punching assembly 14 punch holes in the copper bar. When moving upward, the elastic force of the spring 12 reduces the burden of the upward pulling force.

[0026] A limit piece 15 is fixedly installed on the upper surface of the fixed plate 9, and a second cam 19 is rotatably installed on the upper surface of the fixed plate 9. A connecting rod 21 is hinged on the upper surface of the second cam 19, and a push plate 20 is hinged on the end of the connecting rod 21. The push plate 20 is slidably connected to the inner surface of the limit piece 15. When the second cam 19 rotates, it drives the push plate 20 to move back and forth along the limit piece 15, pushing the punched copper bar forward, so that the operator or the feeding component of the next step can take it away.

[0027] A rotating motor is fixedly mounted on the lower surface of the fixing plate 9, and the rotating shaft of the rotating motor is coaxially fixedly connected with the rotating shaft of the second cam 19.

[0028] Working principle: This kind of copper bar processing high-efficiency punching machine, when in use, uses the loading component of the front process to insert the copper bar to be punched from the side between the fixed plate 9 and the limiter 15, and the servo motor 5 drives the connecting shaft 6 to rotate while driving the first cam 7 to rotate. When the first cam 7 rotates, it will drive the transmission member 8 to move up and down, and at the same time pull the lower punching component 14 up and down continuously. When moving downward, due to the certain gravity of the mounting plate 13 and the punching component 14 themselves, the punching component 14 can impact downward to punch holes in the copper bar. When moving upward, the elastic force of the spring 12 reduces the burden of the upward pulling force, and the residual material after punching falls along the through hole 18 to the recovery basket 17 below for unified recovery. The second cam 19 rotates to drive the push plate 20 to move back and forth along the limiter 15, and push the punched copper bar forward, so that the operator or the feeding component of the next process can take it away.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
