AI Technical Summary

Technical Problem

The width of traditional strip-shaped permanent magnetic chucks cannot be further reduced, which affects the efficiency of side processing of long strip materials. In particular, during machine tool processing, the machine needs to be stopped for adjustment, and it cannot adapt to narrow strip materials.

Method used

It adopts a single-row magnetic block design, which generates magnetism through a row of magnetic steel and reversely set coils. Combined with the pole core and magnetic isolation filler, it can achieve effective adsorption and release of narrow strip materials.

Benefits of technology

The width of the electro-permanent magnetic chuck is effectively reduced, which avoids the problem of affecting processing efficiency due to excessive width and realizes stable adsorption and release of narrow strip materials.

Abstract

The utility model discloses a single-row strip-shaped electro-permanent magnetic chuck, which comprises an electro-permanent magnetic chuck body and a cover plate, the electro-permanent magnetic chuck body comprises a shell, reversible magnetic steel, a coil, a pole core, permanent magnetic steel and a magnetism isolating filler, the coil is wound around the reversible magnetic steel, the permanent magnetic steel is distributed around the pole core, and the reversible magnetic steel is wound around the shell. The pole core is used for leading out magnetism generated by the reversible magnetic steel to the cover plate, the reversible magnetic steel is arranged in a single-row strip shape, magnetism is generated only through a row of magnetic blocks, and in one scheme, two adjacent magnetic steel coils are oppositely arranged, namely, two adjacent magnetic steel coils generate opposite magnetic poles and then respectively cover half areas, and the opposite magnetism is led out through the pole blocks. According to the other scheme, magnetic poles can be generated in the two directions of the coil, the coil is vertically placed, magnetism at the two ends is led out through the magnetic conductive material, in this way, the corresponding magnetic adsorption effect can be achieved through the single-row magnetic blocks, and the width of the electro-permanent magnetic chuck can be further reduced through the scheme.
