Problems solved by technology

[0002] Iron core riveting is usually done manually. The rivets placed in the punching sheet are flanged and riveted by beating with a hammer. The riveting of multiple rivets can only be done one by one. This method is dangerous and has low operating efficiency and low riveting pressure. Uniform; the improved air pressure gun riveting method also needs to rivet multiple rivets one by one, and the above problems still inevitably exist

Abstract

The invention relates to an oil press, in particular to an automatic iron-core riveting machine. A stand-column-type hydraulic machine is adopted, and a plurality of rivets put into punching pieces can be once riveted on a mold. According to the iron-core riveting machine, a hydraulic oil cylinder serves as power for iron core riveting, and an upper mold body is connected with the hydraulic oil cylinder. A lower mold body is arranged on a hydraulic working table and provided with a punching-piece laminating core mold, and a positioning key is arranged on the core mold and used for positioning the stacked punching pieces so that it can be guaranteed that the location degrees of the punching pieces are coincident. The riveting force can be adjusted through a remote pressure regulating valve, and the pressure value is visibly displayed through a pressure meter installed on an electric control cabinet. A jacking oil cylinder is arranged below the table top of the hydraulic working table, a riveted iron core can be ejected out of a mold core upwards through ejector rods, and the iron core can be conveniently taken out. A grating switch is arranged on the hydraulic working table; in the riveting process, if one hand carelessly enters a riveting area, a safe grating detects the hand, interlocking stopping is achieved, and personal safety is protected.

Description

technical field [0001] The invention relates to a hydraulic press, in particular to an iron core automatic riveting press. technical background [0002] Iron core riveting is usually done manually. The rivets placed in the punching sheet are flanged and riveted by beating with a hammer. The riveting of multiple rivets can only be done one by one. This method is dangerous and has low operating efficiency and low riveting pressure. Uniformity; the improved air gun riveting method also needs to rivet multiple rivets one by one, and the above problems still inevitably exist. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned process, the present invention provides an automatic riveting forming machine for iron core, which adopts a column type hydraulic press, and can complete the riveting and pressing of multiple rivets put into the punching sheet on the mold at one time. [0004] The iron core riveting is powered by a hydraulic cy...
