Description

A feeding auxiliary mechanism of a CNC shearing machine

technical field

The application relates to the field of numerical control shearing machine equipment, in particular to a feeding auxiliary mechanism of a numerical control shearing machine.

Background technique

CNC plate shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. It uses the moving upper blade and the fixed lower blade to apply shear force to the metal plate through the gap between the blades, so that the plate is pressed according to the desired Dimensional fracture separation required.

The steel plates are usually stacked on the wooden floor for storage. When feeding the shearing machine, the workers will first use the transport vehicle to put the wooden floor containing the steel plate on the side of the shearing machine, and then use the suction cup mechanism to Pick up the topmost steel plate. The reason why the wooden floor and the steel plate should be operated together is because the gap between the steel plate and the wooden floor is too small, it is difficult for the fork of the transport truck to be inserted between the steel plate and the wooden floor, and it is difficult to remove the steel plate from the wooden floor. After the suction cup mechanism fixes a piece of steel plate, it moves to the top of the shearing machine and then descends. When the steel plate touches the surface of the shearing machine, the suction cup mechanism releases the steel plate to complete the feeding of the steel plate once.

However, this feeding method requires the suction cup mechanism to have strong and stable adsorption to the steel plate, and the adsorption capacity will be affected by the surface cleanliness of the steel plate and the suction cup mechanism, but the steel plate is easy to be stained with dirt such as oil or steel chips. Dirt will adhere to the suction cup mechanism after contact with the suction cup mechanism, thereby affecting the adsorption capacity of the suction cup mechanism to the steel plate. Therefore, the suction cup mechanism needs to be cleaned frequently, and the maintenance cost is high.
