Silicon steel sheet welding with punching device

Abstract

The invention discloses a poking-type sheet sorting device for coiled silicon steel sheet welding, which comprises a down pressing mechanism, a middle positioning mechanism and an up poking mechanismarranged sequentially from top to bottom, wherein the middle positioning mechanism comprises a coiled silicon steel sheet lamination seat for laminating coiled silicon steel sheets; the up poking mechanism comprises an ejecting rod and a punching driving device for driving the ejecting rod to act; the down pressing mechanism comprises a pressing rod and a down pressing driving device for driving the pressing rod to act; the coiled silicon steel sheet lamination seat is provided with a through hole for enabling the ejecting rod to pass through, the pressing rod is internally provided with an inner hole for enabling the ejecting rod to extend inside, and the pressing rod is fixed with or integrally provided with a ring cover abutting against the coiled silicon steel sheet; the ejecting rod ejects in the inner hole of the pressing rod under driving of the punching driving device and simultaneously drives the coiled silicon steel sheets to be bent and upwrapped, the pressing rod downwardlypresses and abuts against the coiled silicon steel sheets under driving of the down pressing driving device, and thus, the coiled silicon steel sheets fall and are sorted to be flattened. Unlike a mode of totally sheet pressing from top to bottom in the case of sheet sorting by a conventional fixture, the device has a mode of poking from bottom to top and down pressing, and excellent sheet sorting effects are taken.

Description

technical field [0001] The invention relates to a chip unscrambling device for silicon steel sheet welding, in particular to a poking type chip unscrambling device for silicon steel sheet welding. Background technique [0002] In order to reduce hysteresis loss and eddy current loss and prevent overheating during operation to reduce performance or even burn out, the stator core of the motor in the known technology is usually laminated with silicon steel sheets and then pressed or welded. Especially for a type of motor used in new energy vehicles and EMUs, the diameter is usually 120mm~1m, and the height is 45mm~1m. Obviously, the above-mentioned silicon steel laminated motor stator must be used to reduce magnetic loss. [0003] When the conventional technology produces the above-mentioned silicon steel sheet stator, the sheets are mainly sorted manually, which is slow, inefficient, and the uniformity of the sheets is poor, and the silicon steel sheets are arched and uneven. ...

AI Technical Summary

Problems solved by technology

Although it is much less labor-intensive than manual stacking, there are still some problems in the actual implementation of this type of film unscrambling fixture and its film unscrambling mode. The most important thing is that the silicon steel sheet is greatly distorted and deformed on the column, and the internal stress is not easy to release, resulting in silicon steel sheets. It is not easy to stick flat between the steel sheets, so the effect of the existing sheet unscrambling fixture is still not good
