Description

Technical Field

[0001] The utility model relates to the technical field of semi-hollow cold heading machines, in particular to a semi-hollow cold heading machine with a shearing system. Background Art

[0002] Cold heading machine is a special equipment mainly for upsetting, which is specially used for batch production of nuts, bolts and other fasteners. The cold heading process is based on the theory of metal plastic deformation. A certain pressure is applied to the metal blank at room temperature to make it plastically deform in the die cavity and form it into a specified shape and size. At present, the shearing system of the semi-hollow cold heading machine mostly uses a hydraulic rod to drive the shearing knife seat to move, and uses the strength of the shearing knife seat to shear the material. However, the material cannot be clamped and positioned during shearing, because the shearing knife seat will have a large impact force when it moves and shears, which is easy to cause material splashing. Therefore, we propose a semi-hollow cold heading machine with a shearing system. Utility Model Content
