Description

Cutting device and relay production line Technical Field The invention relates to the technical field of relay production apparatuses, in particular to a cutting device and a relay production line. Background The relay generally comprises a housing, a frame body assembled in the housing, a magnetic circuit part, a contact part and the like, wherein the magnetic circuit part comprises a coil, a coil frame, an iron core, a yoke iron and an armature iron, and the contact part comprises a movable spring part and a static spring part. In order to facilitate the installation of the magnetic circuit part, a positioning block which is matched with the frame body is arranged on the yoke, and a positioning hole is formed in the frame body. In order to facilitate the positioning block to be inserted into the positioning hole, the positioning block and the positioning hole are in clearance fit, so that the positioning block is required to be deformed to be clamped in the positioning hole in order to enable the yoke to be tightly installed on the frame body. Disclosure of Invention In order to solve at least one of the problems of the prior art, according to one aspect of the present invention, there is provided a cutting device for cutting a yoke in a magnetic circuit portion so that the yoke is deformed and mounted on a frame, the yoke having a positioning block penetrating through the frame, the cutting device comprising a frame, a cutting mechanism mounted on the frame for applying a cutting force to the positioning block so that the positioning block can be clamped to the frame after being deformed, a first driving mechanism mounted on the frame for driving the cutting mechanism to move in a vertical direction so that the cutting mechanism applies a cutting force to the positioning block, a pressing mechanism mounted on the frame and arranged opposite to each other for applying a pressing force in a direction opposite to the yoke and the frame when the cutting mechanism applies a cutting force to the positioning block.
