Benefits of technology

[0017] 1. This continuous chip removal mechanism for punching conductive busbars injects air into an air compressor tank via an air compressor pump, compressing and pressurizing the air. Under the pressure of the air, the conical sealing plug presses against the guide cone surface, thereby sealing the top of the exhaust nozzle. This seals the airflow before punching, achieving pressurization. When the cutter body punches open the copper busbar, the top head pushes upward, causing the conical sealing plug to open upward, allowing the high-pressure airflow to rush out. The high-pressure airflow impacts the dislodged chips downward, causing the chips to be blown downward from inside the punching discharge hole. This eliminates the need for the cutter body to completely pass through the discharge hole, reducing the need to increase the punching stroke of the cutter body and reducing wear. At the same time, the high-pressure airflow can quickly flush out the chips, preventing them from getting stuck in gaps and improving the punching discharge effect.

[0002] In the field of electrical equipment manufacturing, busbars, as key conductive components, have a direct impact on the stability and safety of electrical systems due to their processing quality. Drilling is an essential step in the production and processing of busbars. However, drilling generates a large amount of metal debris. If this debris is not removed in time, it will not only adhere to the surface of the busbar, affecting subsequent processing accuracy and product quality, but may also enter the transmission components of the processing equipment, accelerating equipment wear and even causing equipment failure.

[0031] The following steps are required when using this conductive busbar drilling and continuous chip removal mechanism:

[0032] 1) Air is injected into the air compression tank 11 by the air compressor pump 12, which compresses and pressurizes the air. Under the pressure of the air, the conical sealing plug 174 can press against the guide cone surface 173, thereby sealing the top of the exhaust nozzle 172.

[0033] 2) Then the copper busbar is inserted into the top surface of the punching die 3, and the punching tool holder 9 is pushed down by the hydraulic push rod 7, so that the punching tool assembly 17 punches holes on the copper busbar downwards, and the punching fragments are guided into the punching discharge hole 5.

[0034] 3) When the cutter body 171 punches open the copper busbar, the top head 175 can be pushed upward, which pushes the conical sealing plug 174 upward, thereby allowing the high-pressure airflow to rush out, and the debris that is knocked off is impacted downward by the high-pressure airflow, causing the debris to be blown downward from the inside of the punching discharge hole 5.

[0035] 4) The discharge ramp 16 can make the washed-down debris slide to one side, which facilitates the collection of debris.

[0036] In summary, this utility model injects air into the air compression tank 11 through the air compressor pump 12, thereby compressing and pressurizing the air. Under the pressure of the air, the conical sealing plug 174 can press against the guide cone surface 173, thus sealing the top of the exhaust nozzle 172. This seals the airflow before punching, achieving pressurization. Then, when the cutter body 171 punches open the copper busbar, the top head 175 can be pushed upward, causing the conical sealing plug 174 to be pushed upward, thereby allowing the high-pressure airflow to rush out. The debris that is knocked off is impacted downward by the high-pressure airflow, causing the debris to be blown downward from inside the punching discharge hole 5. The cutter body 171 does not need to completely pass through the discharge hole 5, and there is no need to increase the punching stroke of the cutter body 171, reducing wear. At the same time, the high-pressure airflow can quickly flush out the debris, preventing it from getting stuck in the gaps and improving the punching discharge effect. The discharge ramp plate 16 can make the knocked-off debris slide to one side, which is convenient for the concentrated collection of debris.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
