Example six

The method for feeding and stamping the plate by using the device in the fourth embodiment comprises the following steps:

(1) Preparing, opening a cabinet door, shaking a motor handle to enable the height of a workbench to be consistent with the height of a table top of a punching machine, enabling a plate to be positioned on a discharging plate, enabling a vacuum chuck to be positioned above the plate, enabling a positioning part to be positioned at the front end of a material conveying plate slightly, enabling a positioning part to be positioned at the right end of an upper clamping plate, enabling a fourth cylinder to drive a telescopic rod to shrink, enabling a spring to be compressed, and enabling a second positioning linear displacement structure to drive a second positioning linear to displace to the right end of the material conveying plate;

(2) Taking materials, driving a vacuum chuck to descend by a third air cylinder, sucking a plate on a lower discharging plate by a vacuum generator through negative pressure for the vacuum chuck, driving the plate to ascend by the third air cylinder, driving the plate to translate to a material conveying plate by a second air cylinder, driving the plate to descend by the third air cylinder, placing the plate on the material conveying plate by the vacuum generator through positive pressure for the vacuum chuck, and resetting the vacuum chuck;

(3) Positioning, wherein the fourth cylinder does not apply power, and the spring drives the second positioning line to displace towards the side of the first positioning line due to elastic resilience, so that two side walls of the plate are clung to the roller of the second positioning line and the clamping groove of the first positioning line;

(4) Pushing, namely driving the positioning pin to push the plate to move backwards and enter the guide mechanism by the linear screw module, and driving the positioning piece to move towards the side of the support column (the support column at the rearmost end of the left side of the lower clamping plate) by the fifth cylinder when the end part of the plate penetrates out of the guide mechanism, so that two side walls of the plate are clung to the positioning piece and the support column;

(5) At the moment, the plate is pushed to the punching machine, the screw rod linear module drives the positioning to slightly push the plate to move backwards for a fixed distance after the punching machine punches once, the screw rod linear module drives the positioning to slightly reset and the second positioning line displacement structure drives the second positioning line to reset when the plate completely breaks away from the lower clamping plate and the fifth cylinder drives the positioning piece to reset when the plate and the rest of the plate on the material conveying plate completely enter the guiding mechanism;

(6) When the plate waste is pushed to the traction mechanism, the plate waste firstly passes through the limiting shaft, then the lower pressing cylinder drives the upper pressing roller to contact the plate waste downwards, the plate waste is clamped by the upper pressing roller and the lower pressing roller, the servo motor drives the lower pressing roller to rotate, the plate waste is pulled to move backwards for a fixed distance, and the subsequent stamping process is completed by matching with the punch press until the stamping action of the whole plate is completed;

(7) Repeating the steps (2) (3) (4) (5) (6).

The existing equipment 1 is a famous worker intelligent sheet material automatic feeding machine, and the minimum thickness of the applicable plate is 2mm; under the applicable thickness, the waste material rate of 20% -25% can be generated, and the shutdown phenomenon caused by faults such as stamping tilting and the like exists, so that the equipment is rarely used in actual production.

The existing equipment 2 is a Ke Bote stamping feeder, the minimum thickness of a suitable plate is 1mm, and the existing equipment is industrial equipment with the best automatic stamping effect of the sliding bearing plate at present, but stamping waste is required to be of a frame structure, and production proves that if the existing equipment is of a line structure, defects such as incapability of traction, stamping tilting and the like can be caused. The invention is compared with the above, and the invention progress is reflected through production verification.

The reject rate was calculated as the reject upper surface area/slide bearing plate upper surface area x 100%.
