Description

Technical Field

[0001] The utility model relates to the technical field of copper electrode processing, in particular to a feeding and transmission device used for wire cutting processing of copper electrodes. Background Art

[0002] Wire EDM is the accumulation of free positive ions and electrons in the field, which quickly forms an ionized conductive channel. At this stage, a current is formed between the two plates. This causes countless collisions between particles, forming a plasma zone, which quickly rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some materials on the surfaces of the two conductors. At the same time, due to the vaporization of the electrode and the electrolyte, a bubble is formed, and its pressure rises regularly until it is very high. Then the current is interrupted, the temperature suddenly drops, causing the bubble to explode inward, and the power generated throws the molten material out of the crater, and then the corroded material re-condenses into small spheres in the dielectric fluid and is discharged by the dielectric fluid. Then, through the monitoring and control of NC control, the servo mechanism is executed to make this discharge phenomenon uniform. When copper electrodes are processed, wire cutting is required.

[0003] At present, when copper electrodes are processed by traditional wire cutting on the market, they are usually fixed and embedded in the die for processing. However, during on-site processing, the electrodes are inserted into the die one by one, and then pulled out one by one after processing, which is very labor-intensive and time-consuming. In actual use, a robotic arm and a material distribution conveyor belt are used to process the copper electrodes through a program. Because the clamping head on the robotic arm needs to be used frequently, the probability of damage to the clamping head on the robotic arm increases. The clamping head on most robotic arms is fixedly connected to the robotic arm by a variety of bolts, so that the clamping head and the robotic arm need to be disassembled by a variety of tools, which makes it inconvenient to separate the clamping head from the robotic arm.
