1results about How to "Control up and down movement" patented technology

This utility model relates to the technical field of wire-filling devices, and discloses a high-efficiency carbon brush wire-filling device, including a mounting plate and a cylinder. The cylinder is equipped with a wire-filling mechanism for continuous wire filling. The wire-filling mechanism includes a striking piston rod, which is slidably connected to the cylinder. The cylinder has an upper air inlet, and an upper connecting pipe for connecting to an air injection device is installed on the upper air inlet. An upper solenoid valve for controlling the air intake and exhaust is installed on the upper connecting pipe. In this utility model, the air supply in and out of the cylinder is controlled by the upper and lower solenoid valves, thereby controlling the up-and-down movement of the striking piston rod. Simultaneously, the pressure inside the cylinder can be adjusted to control the impact force of the striking piston rod, thus controlling the striking force of the striking piston rod. This reduces the likelihood of carbon brush cracking and increases pull-out force.
