Description

Technical Field

[0001] The utility model relates to the technical field of metal slitting, in particular to a two-stage metal slitting multiple shear machine. Background Technique

[0002] During the processing of transformer cores, in order to prevent the cores from generating heat and wasting a large amount of electric energy, silicon steel sheets are used for pressing. Silicon steel is steel doped with a small amount of silicon, and its resistivity is larger than that of ordinary steel. Making the silicon steel into thin sheets is to cut off the path of eddy current by means of the insulating paint between the sheets, so that the eddy current is restricted within the narrow thin sheets, further increasing the resistance and reducing the eddy current. Before forming, the silicon steel sheets are steel strips. A metal slitting multiple shear machine is used to slit the steel strips, and the slit silicon steel is wound and packed and sent to a stamping device to be stamped into the required core shape.

[0003] At present, the cutting knives of the metal slitting multiple shear machines on the market are all installed on a slitting shaft. When slitting the steel strip, the cutting knife contacts the steel strip to complete the cutting. In this way, the cutting efficiency is low. At the same time, in order to facilitate replacement, the existing cutting knives are detachably installed on the slitting shaft. In order not to disassemble the slitting shaft during the installation process, the cutting knives are all set in a semicircular shape. However, this design will cause damage to the steel strip during the cutting process. In addition, the slitting shaft of the existing metal slitting multiple shear machine is a single shaft, and the feed distance between the cutting knives is large, resulting in a high defective rate of the cut products. For this reason, the inventor designed a two-stage metal slitting multiple shear machine. Content of the Utility Model
