Structure and continuous stamping and automatic overlapping and assembling method of silicon steel sheets of transformer iron core of welding machine

Abstract

The invention provides a structure and a continuous stamping and automatic overlapping and assembling method of silicon steel sheets of a transformer iron core of a welding machine. During a high-speed continuous stamping process of strip-shaped raw materials of the silicon steel sheets, two silicon steel sheets are simultaneously stamped in each time, and the silicon steel sheets which are stamped in each time can be automatically overlapped together with silicon steel sheets which are already stamped, and the silicon steel sheets can exit until certain thickness is achieved. The automatic overlapping of the silicon steel sheets is realized as multiple bulges are designed on the surfaces of the silicon steel sheets and the pressure action during the stamping process is utilized at the same time, steel sheet iron cores which are subjected to high-speed stamping and overlapped together can exit from a die when the certain thickness is achieved, the continuous stamping and automatic overlapping and assembling method aims at realizing the automatic overlapping of processed silicon steel sheets, and thus a manual sheet overlapping mode in a general processing method can be omitted. The structure and the continuous stamping and automatic overlapping and assembling method, which are disclosed by the invention, have the characteristic of efficient and quick processing, and the production cost of parts is reduced.
