Embodiment 1

[0020] The vibration mode of the traditional actuator is axial vibration, and the vibration direction is along the axial direction of the extension shaft, which is suitable for the part where the normal line of the surface of the processing part is not shielded. The head cannot be touched and is no longer applicable. This embodiment proposes a micro-cold forging device with swing vibration. The hammering direction of the impact head is along the radial direction of the extension axis, which expands the application range of the micro-cold forging device.

[0021] Such as figure 1 As shown, the oscillating surface micro cold forging device involved in this embodiment includes: a permanent magnet 7 and a yoke 8 as a magnetic field generating device, a limiting device and a rotor, wherein: the magnetic field generating device and the limiting device are both connected to the frame Fixed, a return torsion spring 10 as a reset device is arranged between the rotor with the coil 5 and...

Abstract

The invention discloses a swing type surface microscopic cold forging device, which comprises a magnetic field generation device, a limiting device and a rotor, wherein a reset device is arranged between the rotor with a coil and a rack, the magnetic field generation device, the rotor and a workpiece to be processed are sequentially arranged, current is introduced into the coil on the rotor, and the current interacts with a magnetic field generated by the magnetic field generation device to generate ampere force, so that the rotor rotates and acts on the workpiece to be processed to realize processing. The limiting device is used for rapidly changing the impact speed direction, so that energy loss is reduced, the impact frequency is improved, the hammering direction of the impact head is perpendicular to the extending shaft direction, and the application range of the microscopic cold forging device is expanded.

Description

technical field [0001] The invention relates to a technology in the field of cold forging, in particular to a swinging surface micro cold forging device. Background technique [0002] The need to improve the surface integrity and enhance the functional performance of manufactured components has become a driving force in the development of new production methods and high-performance manufacturing technologies. Surface micro-cold forging technology is a new type of surface treatment technology. Compared with shot peening and other similar technologies, it can ensure that the impact strength of the entire processing area is uniform, and does not require special equipment, and can be directly installed on the machine tool as a tool , complete its machining without changing the workpiece clamping. The existing technology of micro-cold forging through electromagnetic field, but the vibration mode of the actuator is axial vibration, and the vibration direction is mostly along the ...
