[CN 201820938779.5] Intelligent Direct Drive Electromagnetic Forging Hammer
[CN 201820938779.5] Intelligent Direct Drive Electromagnetic Forging Hammer Title: Intelligent Direct Drive Electromagnetic Forging Hammer Application Number: CN 201820938779.5 Applicant: Guo Xiaohong Application Date: 2018-6-15 Patent Type: Utility Model The utility model relates to the field of forging technology, specifically an intelligent direct drive electromagnetic forging hammer, including a frame, the upper part of the frame is connected with an upper beam, the inner side of the frame is provided with an upper die and a lower die, the inner cavity of the upper beam, and a cylindrical linear motor, the cylindrical linear motor includes a motor housing, a cylindrical stator and a cylindrical mover. The stator includes several sequentially connected stator units. The stator unit includes an iron core and a coil winding. The iron core is circular and the coil winding is arranged on the inner side of the circular ring. The coil winding is connected to the power supply; the mover includes a mover screw, a permanent magnet, a bead sleeve, and a set sleeve. The permanent magnet is an annular structure with a threaded inner ring, the permanent magnet is installed on the mover screw, the tail of the permanent magnet is provided with a ball guide sleeve, and the tail is axially locked by a set sleeve. The utility model directly generates thrust without any replacement device, and its movement can be without mechanical contact, so that the transmission parts are not worn, thereby greatly reducing the mechanical loss.
