Abstract
The invention relates to the technical field of forging, in particular to an intelligent direct drive electromagnetic forging hammer. The intelligent direct drive electromagnetic forging hammer comprises a rack, an upper cross beam is connected to the upper portion of the rack, an upper mold and a lower mold are arranged on the inner side of the rack, a cylindrical linear motor is arranged in an inner cavity of the upper cross beam, and comprises a motor shell, a cylindrical stator, and a cylindrical rotor, the stator comprises multiple stator units connected in sequence, each stator unit comprises an iron core and a coil winding, the iron cores are annular, the coil windings are arranged on the inner sides of the annular shapes, and are connected with a power source, each rotor comprisesa rotor screw, a permanent magnet, a ball sleeve and a set sleeve, the permanent magnets are of annular structures with the inner rings provided with threads, the permanent magnets are arranged on therotor screws, the ball guide sleeves are arranged on the tails of the permanent magnets, and the tails are axially locked through the set sleeves. Thrust is directly generated without any replacing device, in the moving process, no mechanical contact can be achieved, transmission parts are not worn, and mechanical losses are greatly reduced.
Description
Technical field [0001] The invention relates to the technical field of forging, in particular to an intelligent direct-drive electromagnetic forging hammer. Background technique [0002] The forging hammer is a forging machine that uses a transmission mechanism to move the falling part and accumulate kinetic energy, which is applied to the forging in a very short time to obtain plastic deformation energy and complete various forging processes. The falling part includes piston, hammer rod, and hammer head. , Upper anvil or upper module. Forging hammers have always played an important role in the forging industry. [0003] Although the emergence of other forging equipment, such as hydraulic presses and mechanical presses, has replaced part of the work of forging hammers to a certain extent, until now, forging hammers, especially die forging hammers, are still used in the forging industry of various countries. Dominates, most die forgings are produced on hammers. [0004] The air ham...
