A new type of steel pressing device

Abstract

The invention discloses a novel steel pressing device, which includes a base, a pressing plate for pressing steel, a rotating device for rotating the pressing plate, and a lifting device for lifting the pressing plate; the lifting device includes a lifting device vertically arranged on the base mechanism and a first controller connected with the control of the lifting mechanism; the swing cylinder is arranged on the lifting rod of the lifting mechanism; the rotating device includes a swing cylinder and a second controller connected with the control of the swing cylinder, and the output shaft of the swing cylinder Parallel to the section steel along the horizontal direction; the pressing plate is fixed on the output shaft of the swing cylinder, the length direction of the pressing plate is perpendicular to the output shaft of the swing cylinder, and the swing cylinder drives the pressing plate to rotate in a vertical plane; the present invention Through the cooperation of the cylinder and the rotation in the steel pressing device, when the pressing plate is needed, move the pressing plate to the profiled steel to press the profiled steel to ensure that when the profiled steel and the electromagnet of the palletizer are separated, the profiled steel will not move with the electromagnet; when the pressing plate is not needed, move the The platen moves back to the standby position.

Description

technical field [0001] The invention relates to a novel steel pressing device. Background technique [0002] In the domestic small profile production line, the section steel will be slowly sent to the finished product collection system after being cut to length or cold sawed, and a series of work processes such as palletizing, packaging (bundling), and weighing will be carried out. In order to make the production process and rhythm of continuous rolling more orderly, reduce labor costs, and improve the packaging quality of finished products. In the past, palletizing was mostly manual work, which had the disadvantages of poor packaging quality, low production efficiency, high labor intensity, and high labor costs. Now, in order to adapt to the production process and rhythm of continuous rolling, reduce labor costs and improve the packaging quality of finished products. After being promoted, steel mills began to gradually use automated profile palletizers. [0003] The actio...

Problems solved by technology

[0004] In the above process, the electromagnet of the palletizer puts the section steel on the finished product platform, and then loses power. At this time, the time when the electromagnet of the palletizer loses power is very critical. If the power is lost too early, that is, the section steel has not been placed on the finished platform. When the palletizer electromagnet has lost power and lost its magnetic force when it is on the shelf, the profile will fall on the finished platform, and there will be impact between the profiled steel and the platform or the profiled steel that has been coded on the platform, and displacement will occur, and the profiled steel will no longer Falling in the specified position, causing palletizing failure

If the electromagnet of the palletizing machine loses power too late, when the electromagnet of the palletizing machine puts the profile steel on the finished product stand, it still does not lose power. At this time, the profile steel will still be adsorbed on the electromagnet when it should be separated, and the profile steel The electromagnet of the palletizer moves upwards until the electromagnet loses power, and the profiled steel will fall on the finished product platform under the action of gravity, resulting in palletizing failure

In addition, due to the hysteresis effect of the electromagnet, the magnetic force will not disappear completely synchronously after power failure, and there will be a short retention period, which will also cause the same palletizing failure accident as power failure too late

[0005] It can be seen that the electromagnet of the palletizing machine loses power too early or too late and the existence of the hysteresis effect will cause palletizing failure, but the power-off time is completely consistent with the palletizing action, and it is difficult to ensure an accurate time point.
