Description

Technical Field

[0001] The utility model relates to the field of pin shaft production, in particular to a cutting device for pin shaft production. Background Art

[0002] Thin pins can be used for hinge connections, while thick pins can be used for articulation of large machinery. They have a wide range of applications. When producing thinner pins, the process usually uses a punch to shear the blank rod. The cross-section after cutting by punching is very uneven, and multiple steps are required for subsequent trimming. When producing thicker pins, most of them are turned on a lathe and then replaced with a cutting knife for cutting. When the pin is cut on a lathe, as the cutting knife gradually extends, the radius of the uncut part of the pin decreases sharply, and its linear speed also decreases rapidly. Finally, the center point of the pin cutting position is mostly not cut by the cutting knife, but the radius is too small and is broken by the cutting knife. This will form a raised defect at the center of the cut surface of the pin, which also requires additional trimming. Compared with the patent with application number 201920243475.1, a pin cutting device is disclosed. This patent uses stamping to cut the pin, which cannot avoid the above problems, and can only cut and process one pin at a time, with low cutting efficiency and poor cutting effect. Utility Model Content

[0003] In order to overcome the deficiencies in the background technology, the utility model discloses a cutting device for pin shaft production. The utility model drives the rotating head and the blank rod fixed in the rotating head to revolve through a first turntable. At the same time, since the small gear on the rotating head is engaged with the stationary large gear, the blank rod will also rotate. The linear speeds of the blank rod's rotation and revolution are the same in the outer direction and will be superimposed. When the cutting knife is cutting, the problem of insufficient linear speed and inability to cut will not occur. Twelve blank rods can be fixed and processed at the same time through no less than twelve rotating heads and stable heads, with high cutting efficiency and high cutting quality.
