Technical Field

The invention relates to a sheet metal processing production device, in particular to a sheet material exchange device and a sheet material exchange method based on a sheet material warehouse.

Background

The sheet metal processing or other fields that involve panel storage and circulation, need 2 vertical edges of panel and other equipment or the relative position of device to keep fixed a certain time, take the sheet metal processing industry as an example, sheet metal is placed on the mesa of numerical control punch press and is used for punching a hole, processing such as side cut, have 2 or more clamps on the numerical control punch press and be used for pressing from both sides tight panel, the perpendicular face of this clamp is used for the spacing of one limit of panel simultaneously, another limit (this limit is perpendicular with the limit of being held) of panel is spacing by the fender finger (backing pin) of lathe. Thus, for each sheet to be processed, the two edges on which the sheet is positioned are fixed relative to the table of the machine, so that each sheet has a consistent reference relative to the machine.

The modern industry is about to enter the 4.0 era, china also proposes the strategy of manufacturing 2025 in china, taking the sheet metal working industry as an example, the traditional production mode is being replaced by the numerical control production mode, and the numerical control punch press and the laser cutting machine are necessary production equipment of the modern sheet metal factory. When the plate to be processed is placed on the table top of the machine tool, the machine tool automatically processes according to a pre-programmed program. At the present stage, most of numerical control punching machines and laser cutting machines adopt manual feeding, so that the labor intensity of operators is high, the production efficiency is low, and the maximization of the equipment capacity is not facilitated.

The development trend of sheet metal products is various types and small batch, and the competition among sheet metal factories is the competition of production efficiency to a great extent, and the conventional manual feeding mode is still unavailable, so that the sheet metal machining industry has very urgent requirements on an automatic feeding and discharging device for sheets; although some imported high-end machine tools are provided with automatic loading and unloading devices, the automatic loading and unloading devices are special for special machines and are expensive; at present, the automatic plate feeding and discharging device developed by a third party is difficult to accurately feed plates to a specific machining position of a machine tool at one time, and the specific process is that after a sucking disc of the feeding and discharging device puts the plates on a tray on the table top of the machine tool, the plates are manually pushed to the positions of a clamp and a stop finger to be correctly positioned, because the plates on the tray are inclined, and the feeding and discharging device does not have the plate correcting function; therefore, if the existing automatic loading and unloading device does not have manual intervention, the scrapping of partial parts or whole plates or even the separation of the plates from the clamp in the machining process can possibly cause the damage of a machine tool, and the automatic loading and unloading device cannot realize the real automatic loading.
