Description

[0001] High-efficient press system [0002]

The present invention relates to a high-efficiency press system, and more particularly to a high-efficiency press system in which a press material is supplied and conveyed on both sides (or both sides or left and right sides) of a large press, (2-way) simultaneous press to achieve high-efficiency press work more than twice.

Generally, a press for press-forming a metal product or a metal part with an upper and a lower mold includes a carrying-in step of putting a material into a press mold before and after molding, a molding step of press-molding the material carried in the mold, The material is adsorbed to the periphery of a press (press line) or the press process (press line) since the carry-out process of discharging the discharged material from the mold and the transporting process of transferring the taken out material to the mold of the next forming process are carried out. , A press material transfer system or device is installed and used.

On the other hand, when the size of the press-formed material is small and the weight is light, it is possible to achieve the carry-in and carry-out, transfer and discharge of the material depending on the number of workers (hand work), but many workers are required, In addition, productivity is greatly reduced and there is a risk of safety accidents. In some cases, high-cost multi-jointed robots achieve material carry-in, carry-out, transfer, and discharge.

The articulated robot has a structure in which the arm is long and the working radius is large and the installation space between the presses is very large and the moving movement line of the material between the pressing processes is long. Thus, the speed and productivity are poor, There is a problem that profitability is lowered.

In addition, there is a problem in that, if the material to be transported needs to be reversed or rotated according to the working environment or material change, it can not be dealt with quickly, and there is a problem in that it is required to be used one by one with an arm having a length corresponding to the installation condition.

Further, in the case of a press for simultaneously molding a material carried in a plurality of upper and lower dies, means or apparatus for efficiently transferring the press-formed materials to a die of a post-process (a succeeding die or a rear die) (Line), and there is a problem in that the material transfer efficiency is low and the productivity of the press is inferior due to the one-way press method in which the material is fed and transferred while being press-formed and then discharged in the other direction of the press process .
