Problems solved by technology

[0007] 2. The structure is relatively complex, the failure rate is high, and maintenance is difficult
There are too many rotating and moving parts, and the piston rings, copper tiles, and bearings are all vulnerable parts. After a period of use, the piston rings will leak and the hammer will be weak.
[0008] 3. No energy saving
Due to the high power of the motor, it is difficult to start. When the hammer head does not need to move, the motor must also run idle.
[0009] 4. The number of hammer blows is not adjustable
[0010] 5. High cost

Abstract

The invention relates to an electric direct driving type impact forging hammer and belongs to the technical field of forging equipment. The electric direct driving type impact forging hammer is an impact forging hammer driven by a linear electric motor and is characterized in that the hammer head of the electric direct driving type impact forging hammer is directly driven by a three-phase alternated current linear electric motor, and the three-phase alternated current linear electric motor can be applied to a maglev train and the take-off of an aircraft carrier airplane and can directly convert electric energy into mechanical energy in the form of linear motion without a middle switching mechanism. The electric direct driving type impact forging hammer has the advantages of simple structure, small mechanical abrasion, low failure rate, small maintenance work load, durability, and the like. No middle switching process is adopted, the hammer head is directly driven by a three-phase alternated current linear electric motor, the three-phase alternated current linear electric motor is powered off when the hammer head has no action, the energy-saving efficiency is high and the noise is low. With a compact structure and a more scientific and reasonable driving principle, the electric direct driving type impact forging hammer is an ideal updated product of a traditional air hammer.

Description

technical field [0001] The invention relates to an electric direct-driven impact forging hammer, which belongs to the technical field of forging equipment and is an impact forging hammer driven by a linear motor. Compared with the existing air hammer, it has the advantages of simple structure, advanced driving mechanism and low failure rate, and can be widely used in equipment manufacturing, machining and other industries. Background technique [0002] Forging is a pressure processing method that applies an external force to a metal blank to cause plastic deformation to obtain a mechanical part blank with a certain size, shape and internal organization requirements. It is a commonly used forming process in mechanical manufacturing. [0003] Large-scale forgings are mainly completed by large-scale forging equipment such as hydraulic presses and hydraulic presses, and small and medium-sized forgings are mainly completed by steam hammers, splint hammers and air hammers. Due to...
