Abstract: A core wire processing system includes a frame and an electrochemical corrosion section arranged on the frame, wherein the electrochemical corrosion section comprises a core wire corrosion device and the electrochemical corrosion section comprises an electrolytic tank, a cathode, and anodes; the cathode is connected to a negative pole of a DC power supply, and the anodes is connected to a positive pole of the DC power supply; an outer contour of the cathode is designed according to a design size of a core wire, and the anodes comprises a plurality of core wires; electrodes are placed in the electrolytic tank, with the cathode located above the anodes, and are not in direct contact each other; and inside the electrolytic tank is filled electrolyte.

Abstract: A frame fork for a bicycle includes a main tube, two support tubes, a fork head including a bracing tube and two legs integrally formed together, and a sleeve including a sleeve body and two limbs integrally formed together. A center hole is formed in the sleeve body. The bracing tube passes through the center hole of the sleeve body and the lower end of the main tube. The sleeve body embraces the lower end of the main tube. Each leg of the fork head and a respective limb of the sleeve are force fitted into each upper end of the support tube.
