In the embodiment of fig. 6 and 7, the present invention is schematically illustrated when the two side lifting devices 200 are out of sync and the two side rail feeding device 300 is out of sync.
When any one of the above conditions occurs, the length and angle of the cross rod 500 need to be adjusted to a certain extent, at this time, the change of the length of the cross rod 500 mainly depends on the cross rod length adjusting device 401 on one side or two sides, and the cross rod length adjusting device 401 passively slides in a telescopic manner along the guiding direction of the following device 400 under the corresponding guiding action, so as to protect the cross rod from being obviously stretched or compressed; when the lifting devices 200 at two sides are asynchronous, the lifting devices are mainly realized by carrying out certain rotation adjustment on the cross rod 500 around the mandrel of the adjusting device 406 along the forward direction or the reverse direction of the rotation direction 003; when the two-side feeding devices 300 are asynchronous, a certain rotation adjustment is mainly performed by virtue of the forward direction or the reverse direction of the cross rod 500 around the mandrel of the adjusting device 406 along the rotation direction 004; when the two-sided lift device 100 and the cross beam feed device 300 are out of synchronization at the same time, the cross beam 500 is rotationally adjusted about its respective rotational spindles about the adjustment device 405 and the adjustment device 406. The rotation angle is maintained within a set range as the crossbar 500 rotates about the adjustment means 405 and 406, such as: 7 deg..
Fig. 9 is a schematic view of a crossbar rotation according to the present invention.
Fig. 10 is an enlarged schematic view of section II of fig. 9 in accordance with the present invention. In the embodiment shown in fig. 9 and 10, when the upper die and the lower die have a certain angle, the device can timely adjust the gesture of the cross rod 500 entering the die area according to the opening angle of the die, so that the minimum slide block opening height of the press is fully utilized, the matching time of the carrying device and the press is shortened, and the production beat of the stamping equipment is improved.
Fig. 11a-e are schematic illustrations of the gestures of the present invention at run-time for each key point.
FIG. 11a shows the zero position of the handling device, which is the initial position of the handling device when in operation, and is also the holding position when the handling device is out of operation;
FIG. 11b shows the handling device in a pick-up point waiting position, in which the cross bar 500 is waiting to enter the press mold area, in which the handling device is waiting for the press ram to open a certain opening height, allowing the cross bar 500 to enter the mold area;
fig. 11c shows the pick-up point position of the handling device, when the crossbar 500 is directly above the plate-shaped element for gripping the plate-shaped element. In the process of moving from the material taking waiting point to the material taking point, the cross bar 500 can be adjusted by a certain angle according to the opening angle of the die;
fig. 11d shows the position of the loading waiting point of the handling device, where the cross bar 500 carries the plate-shaped element waiting in this position for the opening of the following press ram by a certain height, allowing the cross bar to carry the plate-shaped element into the mould zone. In the process that the carrying device moves from the material taking point position to the material discharging waiting point position, the cross bar 500 carries the plate-shaped part to carry out corresponding angle adjustment in the process so as to keep the cross bar 500 in a horizontal state;
fig. 11e shows the position of the discharge point of the handling device, where the cross bar 500 carries the plate-shaped element to the discharge point. In the process of moving from the material discharging waiting point position to the material taking point position, the cross rod 500 can be adjusted by a certain angle according to the opening angle of the die, after the plate-shaped part is placed at the material discharging point by the carrying device, if the carrying device continues to carry the plate-shaped part, the carrying device moves to the material taking point waiting position, otherwise, the carrying device moves to the zero point position, and in the operation process, the angle of the cross rod 500 is adjusted to the horizontal position.
In a particularly preferred manner, two or more sets of such plate-shaped part handling devices constitute a plate-shaped part handling system of an automated stamping line.
The invention also provides a method for grabbing plate-shaped parts in the upper press die area or the upper station by utilizing the carrying device of the stamping line press or the multi-station press and carrying the plate-shaped parts to the lower press die area or the lower station, which comprises the following steps:

2) Lifting the lowering of the case 200 to lower the height of the cross bar 500;
3) The adsorption device on the cross bar 500 adsorbs the plate-shaped parts;
4) Lifting the lifting bin 200 to move the cross bar 500 away from the lower die area of the upper press;
5) The cross beam 300 moves along the axial direction thereof, so that the cross beam 500 and the plate-shaped part move into the lower molding press mold area;
6) Lifting the case 200 down to lower the height of the cross bar 500 while the adsorption device 501 releases the plate-shaped parts;
7) Lifting the lifting bin 200 to move the cross bar 500 away from the lower die area of the progressive press;
8) The cross beam 300 moves in its axial direction into the upper press waiting position.
