A method and device for synchronous feeding and feeding of a whole roll of thin plate coil barrel

Abstract

The invention relates to a method and device for synchronously supplying and feeding entire rolls of sheet coil stock through transverse and longitudinal rolls. The method for synchronously supplying and feeding entire rolls of sheet coils through the transverse and longitudinal rolls comprises the following steps: unfolding a coil stock, guiding and turning over a sheet material strip, and enabling the transverse and the longitudinal rolls of the sheet material strip to feed synchronously; the device for synchronously supplying and feeding entire rolls of the sheet coil stock through the transverse and longitudinal rolls comprises an uncoiler, the coil stock unfolding direction of the uncoiler is matched with the feeding end of a lower material supporting frame, the upper part of the discharging end of the lower material supporting frame is perpendicular to the lower material supporting frame and is correspondingly provided with the feeding end of an upper material supporting frame, an upper material supporting transverse feed motion system is arranged at the material discharging end of the upper material supporting frame, a front feeding device is arranged at the feeding end of the lower material supporting frame, a rear feeding device is arranged at the discharging end of the upper material supporting frame, and the front feeding device and the rear feeding device are synchronous. The problems of proximity switch damage and rub cut part scrapping caused due to that a material supplying device gives relatively slow responds to signals of a proximity switch or material supplying errors of the material supplying device are relatively great, and the proximity switch is in touch with unfolded material rolls, can be solved.

Description

technical field

[0001] The invention relates to a method and a device for synchronously feeding and feeding whole rolls of veneer rolls. Background technique

[0002] At present, when a production enterprise uses coil material as a raw material for stamping machine parts, after purchasing coil material with a standard width (that is, the width of the plate directly rolled by the rolling equipment, for cold-rolled silicon steel coil material, usually not exceeding 1300mm), according to The size and shape of the parts to be stamped are nested. After determining the layout plan according to the principle of improving raw material utilization and improving production efficiency, the coil material should be cut into suitable strips, which is the traditional cutting process. The strips that have been opened are manually sent to the bottom of the punching machine for stamping. If the amount used by the production company is large enough, he can customize coils with a width suitab...
