Description

Technical Field

[0001] The utility model relates to the technical field of crank production equipment, in particular to a crank forging and extrusion tooling. Background Art

[0002] The crank is a bicycle accessory. A loose crank will often make a clicking sound. When checking the crank problem, first turn the crank to a horizontal position, press down on both sides of the crank with force, then turn the crank 180 degrees, and repeat the same action. If the crank shakes, the crank fixing bolt should be tightened. The crank of a new bicycle should be checked frequently.

[0003] In the existing crank production process, the bar material is first heated to the process temperature, and then the blank is formed into a cylindrical shape, and then the mold is used for one-time molding. After that, the molded product is finished and trimmed, and finally heat treated. It is inconvenient to load the material and it is not convenient to position the raw material on the mold to a suitable position during loading. At the same time, a large amount of dust and slag will be generated during extrusion. Therefore, a crank forging extrusion tooling is proposed to solve the above problems. Utility Model Content
