Description

Technical Field

[0001] The utility model relates to the technical field of NdFeB strong magnetic production tools, in particular to a tool for NdFeB strong magnetic production. Background Art

[0002] NdFeB can be divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and corrosion-resistant. Jigs are a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. They are mainly used as a tool to assist in controlling position or movement. Jigs are used to produce strong NdFeB magnets.

[0003] The utility model with the existing authorization announcement number CN219649700U discloses a tooling jig for electromagnetic pure iron parts, including a base, a top mold and a side clamp assembly. A cavity is arranged between the base and the top mold, and a plurality of electromagnetic pure iron parts can be accommodated side by side in the cavity. The side clamp assembly includes a first side clamp, a second side clamp and an adjusting screw. The first side clamp and the second side clamp are both provided with a clamping portion extending toward the cavity. The adjusting screw passes through the first side clamp and the base in turn and is threadedly connected to the second side clamp.

[0004] By adopting the above technical scheme, the non-processing area of ​​the electromagnetic pure iron piece is fitted and clamped by the base and the top mold to increase the pressure area of ​​the electromagnetic pure iron piece and reduce the possibility of deformation. At the same time, multiple electromagnetic pure iron pieces can be placed in the cavity at one time, which is conducive to batch processing. Secondly, the two sides of the electromagnetic pure iron piece are clamped by the first side clamp and the second side clamp to increase the stability of the clamping. The tightness of the clamping of the first side clamp and the second side clamp can be adjusted by rotating the adjusting screw. However, in the above technical scheme, when the jig is used to clamp the workpiece for processing, a part of the workpiece is blocked by the jig and cannot be processed, and the workpiece needs to be turned over manually, which wastes manpower.
