Description

Technical Field

[0001] The utility model relates to a cold heading machine, in particular to a double-head cold heading machine. Background Art

[0002] In the manufacturing process of circular rigging, cylindrical blanks need to be roughened at both ends, resulting in diameters slightly larger than the center. To achieve this, a cold forging machine is used to roughen only one end of the blank, and then a punch press is used to roughen the other end. This process is complex and expensive.

[0003] The cold heading machine currently on the market consists of a frame, drive mechanism, mold, feed mechanism, shearing mechanism, transfer mechanism, and punching die mechanism. The drive mechanism primarily consists of a motor, reduction gear, and crankshaft. The punching die mechanism primarily consists of a connecting rod and a ram. The mold is mounted on the frame, with the ram slidingly cooperating with the frame. The drive mechanism drives the ram to slide on the frame. The feed mechanism delivers the straightened, circular steel wire to a designated shearing mechanism station. The shearing mechanism cuts the wire into cylindrical blanks. The transfer mechanism transfers the blanks between the movable and static molds. The punching die mechanism pushes the blanks into the mold and roughens one end of the blank, creating a one-die, two-punch cold heading machine. This cold heading machine structure only roughens one end of the blank. To roughen both ends, a punch press is required to roughen the other end, preventing the goal of roughing both ends directly using the cold heading machine. Utility Model Content
