Soft magnet equal-length shearing device

Abstract

The invention discloses a soft magnet equal-length shearing device. The soft magnet equal-length shearing device comprises a first supporting plate and a cutting assembly; the cutting assembly comprises a third rotating shaft, a driving part is connected to the third rotating shaft, a cutting driving arm is connected to the side wall of the third rotating shaft, a second fixing block fixedly connected with the first supporting plate is arranged below the cutting driving arm, a cavity is formed in the second fixing block, a first through opening communicating with the cavity is formed in the upper portion of the middle of the second fixing block, a second through opening communicating with the cavity is formed in the lower portion of the middle of the second fixing block, and a soft magnet can penetrate through the second through opening; and a first connecting block is arranged in the cavity, a first moving block is connected to the upper end of the first connecting block, a cutter is connected to the middle of the lower end face of the first connecting block, first elastic springs are arranged on the two sides of the cutter, and the first connecting block is connected with the inner bottom wall of the cavity through the first elastic springs. According to the shearing device, the shearing length of the soft magnet body can be adjusted, and equal-length shearing treatment is achieved.

Description

technical field [0001] The invention relates to the technical field of soft magnet processing in door curtains, in particular to a soft magnet equal-length shearing device. Background technique [0002] Soft magnets are soft magnets with small coercivity and easy magnetization and demagnetization. The so-called soft means that it is easy to magnetize, and it is "soft" magnetically. In general, soft magnets also exhibit the normal properties of permanent magnets. But when the ordinary permanent magnet is very close to the tapered tip of the soft magnet, the direction of the magnetic moment of the soft magnet changes, and the repulsive force between the two suddenly turns into an attractive force. [0003] There are soft magnets on the door curtains used in daily life. In the production process of the door curtains, the rolled soft magnets need to be transported and cut, and then installed on the door curtains. During the cutting process of the soft magnets, now The isometr...

Problems solved by technology

[0003] There are soft magnets on the door curtains used in daily life. In the production process of the door curtains, the rolled soft magnets need to be transported and cut, and then installed on the door curtains. During the cutting process of the soft magnets, now Some soft magnets are still cut with scissors or semi-automatic mechanical cutting by workers. In addition, when cutting with equal length, the adjustment of the cutting length cannot be realized.
