Description

Metal plate cutting device {Apparatus for cutting metal plate}

The present invention relates to a metal plate cutting apparatus, and more particularly, to a metal plate cutting apparatus for cutting a metal plate to a predetermined size.

In general, a single molded product is manufactured through a molding operation through a press, and the press operation is a mechanical device that forms or cuts a steel plate by inserting a steel plate as a processing material between the upper and lower molds. The iron plate was put between the upper and lower molds by hand and operated by pressing, but this is a work that workers avoid as well as productivity due to the high risk of industrial accidents. The press processing operation is being automated by using a supply device that supplies the material iron plate.

In recent years, an automatic manufacturing system using a multi-axis driven robot has been developed and used in the work site. In order to handle the difference in the various shapes of each component part and each component part supplied from various paths in the previous process, each component A plurality of robots corresponding to the parts will be installed.

In particular, in order to automatically load and unload the material in the press, a material conveying device for adsorbing and transferring the material loaded on the table is installed in a robot installed on one side of the press.

The material transfer device is provided with a plurality of adsorption means for adsorbing the material by vacuum, and the adsorption position of the adsorption means is also changed according to the size and shape of the material.

Accordingly, the conventional technology has the inconvenience of having to manually adjust the center of the adsorption means by the operator according to the size and shape of the material, and since it is done manually, it is not possible to accurately adjust the adsorption means to the center of the material. Accordingly, there was a problem in that the material could not be accurately transferred to the position of the next process, resulting in a defect. In addition, there is a problem in that production efficiency is deteriorated as the press forming operation is stopped entirely due to the manual center adjustment operation and production is stopped.

In addition, when a plurality of materials are adsorbed at the same time when a material is adsorbed, one sheet is not automatically separated, so there is a hassle of removing the material into a separate place and separating the material individually.
